 11.45, so let's begin. Good morning, good evening, and good afternoon, depending upon which time zone you're joining us from. Welcome to this webinar being organized jointly by the Water Channel and IIT Delft. We have been organizing these webinars as a way of reaching out to former students of IIT, but also to the water sector at large. Through the webinars we share from time to time the latest in water management research and education that is coming out of IIT and indeed from the Water Channel. The webinars are free to attend and open to all. We see some value in keeping these webinars open. We think that by engaging in a certain amount of sharing and exchange as opposed to buying and selling the whole water sector benefits in a way which also benefits us as individual professionals and as organizations. We are happy to have at the webinar today someone who has been spearheading the idea of openness in water education and in data-driven water management at large. He is Hans van der Quest, senior lecturer at the Department of Water Resource and Ecosystems at IIT. As a teacher, Hans champions and promotes the use of open source tools for teaching and learning. As a specialist and in remote sensing and GIS, he keeps promoting and developing tools and data sets that are open and accessible to a wide range of people who work in the water sectors, students, teachers, water managers, farmers, government organizations and so on. The latest in this endeavor is a book called QGIS for Hydrological Applications which he has co-written with Kurt Menke. I hope I pronounce Kurt's name right and it is a book I would really recommend to all of us gathered here in this webinar and I will just share the link to the book in this chat box. This is an Amazon but this is a link on Amazon but the book is also available on several other platforms. So with that brief but hopefully sufficient introduction, I would like to hand things over to Hans himself. We look forward to hearing from him and learning about various opportunities for open source learning in water management that are out there but hopefully also to understand a bit how does the open source ecosystem work? What incentives do creators of open source material have? I'm sorry is the audio clear? Can everybody hear me? Okay, okay so I'll just go ahead. So I was saying in course of the webinar we also hope to understand a bit how the open source ecosystem works. What incentives do creators of open source teaching and learning material have to keep creating such material? If there is a business model underlying open source processes and so is open source really the future of learning? Before that I would like to point out some housekeeping stuff. We would like to keep this webinar interactive so we invite you to keep sharing questions and comments that come to your mind during the webinar. You can do that in the chat box here that you can see. We will keep collecting your questions and comments and discuss them during the Q&A session which will follow Hans's main presentation. So without further ado I would like to hand things over to Hans. Hans please take it away. So welcome everybody. I think the introduction by Abraham was okay. I will add a few more things during the presentation. You've seen these poll questions on your screen so if you haven't answered them yet please go ahead. We use that also to summarize in the end a bit the findings. Okay so welcome all especially our alumni. I've seen a lot of familiar names around. Great that you can attend and I hope these slides will help you to discuss with me at the end the things related to open education. We need to distinguish a bit that open source is used mainly for source code so open source software. I had already a previous webinar on open data so in that case we call it open data or open access and this one is about open education for water professionals and I made this presentation together with Raquel Dos Santos and Jepke Koster who both work in the Education Bureau and help me with gathering statistics and advising on the presentation. Now open education we have heard about a lot of terminology in the last few years like MOOCs, open courseware, e-learning and yeah what does it mean and why are we doing it. So I would like to pose a first question to you all like if you are a developer of courses why would you do what is the most important objective you want to achieve with e-learning? Still take a minute and you think about if you yourself can distribute educational materials why would you choose for e-learning what is the most important objective for you. I see there reach more people from far away places that's a good one to learn at our pace and suitabilities I think that's also a very good one cost effective yeah could be see a few more affordability for students yeah especially if it's about open education access ideas at the global level yeah fantastic okay see the answer still coming in very good we will report those after this webinar together with the video but let's have a look at what others came up with in during workshops that we had at IHC Delft so I'm also coordinating e-learning with our partners so if you're interested in that you can also contact me it's funded by the DHC2 program and these things came up with our meetings with for example WaterNet increasing the impact by training more people on water related topics improve the cost effectiveness also mentioned by US participants here to reduce the needs for students to travel between different hosting universities that happens of course a lot in our work especially if you work in a network facilitate the sharing of educational materials between the partners also very important the sharing component also use it to update existing curricula I'm going to talk a lot about that how you do that in a proper way in developing new innovative curricula and attract more participants in that way organize professional short course in an online format so you can offer them much more often than you do with the face-to-face courses and there's also a quality control that you can do in another way which needs to be developed for online it's always used as an excuse not to do it but I think it's there's also arguments to do it and improve the quality control with different e-learning approaches very important for you as alumni is with e-learning we can also support more the lifelong learning after graduation with IHE it doesn't stop science develops insights in the world develop and it's good if we keep in touch with each other and facilitate lifelong learning through online participation and it's green also very important these days I personally want to fly less for my work and I see that e-learning is a nice opportunity for me to organize trainings in any place in the world without flying and I think it's very important also for IHE to reduce our CO2 footprint and in these days we can even add to that today it came out in the news that 290 million school children are kept home because of corona what if the schools and the facilities were there for for e-learning then this time would not get lost and you can use it even as opportunity to learn new things through the internet so a lot of advantages of doing that here at IHE Delft we have different modalities for e-learning we have professional diploma courses that can also be used in so-called blended learning mode so you have face-to-face which is then mixed with online components and available on our website as online courses there's also online courses at the master level which can also be used for lifelong learning we are thinking more to moving to shorter courses instead of the full five ECTS ones that also reduces the price but we also think that there is a more interest in shorter components and I would be glad also to hear that from you in the discussion so you can make some remarks on that in the chat window for these you pay a tuition fee for these first two and we target their professionals which already have a bachelor level and are proficient in English we also test that then there are MOOCs there's open course where open educational resources and webinars like that like these that are offered for free where MOOCs we could offer also a small fee for a certificate if you want a certificate so there are different open modalities available so we had a nice MOOC from AFRI Alliance I'll come back to that later we had webinars several ones like these here you see an example in cooperation with Australian Water School where we all were in different parts of the world and we have open educational resources such as my YouTube channel on GIS for example but what does open really mean well there's a clear definition of open that's also used for open source software or open data so here this the definition talks about data but you can imagine also other kind of resources a piece of data is open not only if everybody is free to use it but also reuse it and redistribute it and there can only be two restrictions to that that is to attribute to the source so if I put my materials as open courseware on the web then and you want to reuse it then you need to attribute you need to say that it comes from from Hans van der Krust from IHE Delft and another restriction you could put on that is share a like which means that everybody who derives things from this as also to put an open license on it and share it in the open way then there are several licenses you can put on your open courseware or on your courseware in general and these are the completely open licenses it's a very boring topic so I'm not going to spend too much time on this we call this also copy left as a contrast with copyright and I think it's very important that you know that these ones are the real open licenses but in general we use different ones also at IHE Delft we don't use the real open license but we use the Creative Commons non-commercial license CC by NC also this presentation is licensed CC by NC and this means that everybody in the world can use these materials for free but you're not allowed to make your own business out of that so that means that universities abroad are free to use my materials I don't have a problem it's always good to ask but if you are going to give paid courses commercially then yeah then we have a problem so it's very important that if you develop course materials that you license it in a proper way and that you know why you put a certain license on that and of course we want to spread knowledge but we don't want to build the business too much in for others without getting revenues ourselves so then we have the traditional course development at IHE where we start with our MSE module so the lecturers here develop lots of course materials for master modules that are taught here at IHE Delft face-to-face and then some of these courses become available as short courses that you can join here at IHE also and sometimes we get specific requests to make courses for customers that can be government or private sector there's also subsidies for example from NAFIC to do that and then we sell parts of those existing modules as tailor-made trainings that's the traditional way it has some disadvantages and the first disadvantage is that teaching materials are mostly developed with subsidies because our education part receives a lot of subsidy money and that part doesn't have many requirements to innovate so there's no drive to innovate I put it very black and white of course it's up to the lecturer to innovate or not but given the money that comes in for this there's no real drive to innovate also the scholarships that many of our participants receive are not really an incentive to be competitive with the market the self-players are more driving the the competitiveness and that's increasing with the years but the scholarships aren't really doing that and by packaging your modules also as short courses that externals can follow you break the learning curve because each time you get external participants and you need to start over again with teaching the basics unless you put a requirement there to follow prep courses we do have requirements to follow the courses but it's very hard to test it so there's a nice opportunity for e-learning to introduce their prep courses then we got into this era where we need to do everything online and we see it in the strategies but nobody really has a great vision on why should we do it so I call this spaghetti and this means that yeah well we start from our msc modules and we open parts online and we produce different online stuff and all these arrows can be connected in a random way but there's no real strategy behind this even not a business model which is very important if we want to do it so therefore this first question that I ask you why should we do this and that's very important so now for something completely different if you know Monty python this comes of course from Monty python what if we want to redesign our education based on this new insights of e-learning and using the the technology that is available these days then we need to really look at different things that we know so where does the money enter the system and that is when we sell our tailor-made advice and training so here in the liaison office our colleague Mita is coordinating our tailor-made training and advice where companies government anybody can request specific trainings from our experts and are willing to pay for that and it's based on the market needs by definition which means that it gives us a billable time and a budget to develop the course materials and in that way also is an opportunity to innovate and be the state of the art so we should really use that to innovate in our teaching then what can we learn from the corporate sector well very strange picture here that I took in the supermarket some decades ago we only had a one type of peanut butter in the Netherlands was just made of peanut and some oil and maybe some sugar was added it was a very simple product but nowadays you can see so many flavors and so many brands and as you know this is the era of caramel sea salt so there's even caramel sea salt double roasted peanut butter available so basically we can learn a few things we can sell the same peanut butter with different labels for a different price and we can add value to the peanut butter we can add some cheap ingredients and basically double the price so that has to do with an economic principle that we need to know the value chain of our products and services so what is the value we're going to add and we can ask money for and where does our market want to pay for it so that's very important then what can we learn from online services that are available because going online with e-learning is very similar to online products that we use here you see the example from Dropbox it's also like Google Google Drive you can get the basic stuff for free and if you get convinced and really want to use extra features then you're going to pay so I'm a happy paid customer of Dropbox and I get all these extra features and I pay quite a nice fee every year for that and I'm willing to pay because I know what I get for that and I got teased by the basic product so that's what you can do that's what we call a freemium business model so there's a value chain but you start with a free product that could be our open education materials and then what can we learn from the open source business model which you might know I'm quite active in the QGIS community which is a beautiful community to to work with and the main thing is that we don't compete with the product itself so the product has a very high value so the QGIS software but it doesn't have a monetary value for us because everybody who works around in this community does a job with it so you either sell your services for people who need help with QGIS or you sell courses or even if you sell if you have free courses in it there can be revenues from that I'll come to that with the value chain and there are companies who want improvements they want maybe plugins developed so you can agree that that goes them back to the to the community and it becomes available for every user of QGIS so in that way we can improve the software increase the amount of users and build this very nice community where you can also become a part of so basically this means and now I'm going to disappoint a lot of our educators here in the virtual room sorry your educational material is very valuable but doesn't have monetary value but what we do sell is the experience so this is the good news you are the added value because you provide the experience as a known or renowned expert and the way you teach is added value so basically that becomes our value chain I'm going to present a nice case study and it's a nice coincidence that today also national water of Uganda is visiting us and they were a basis of this case study because in 2015 I was developing a tailor-made training for national water in Uganda in cooperation with FITAN's AVIDAS International and we agreed with all the stakeholders to publish the materials as open courseware on our open courseware website of IHE and they all agreed with that and that was great because that was the starting point for me to record all the lectures and put it on a youtube channel and embedded in eCampus that's our online platform based on Moodle also open source and also to record all the exercises and publish it there and then it gained momentum and here we are celebrating today our seven years of the open courseware website if you haven't looked at it please take a look it's on ocw.un-ihc.org we can also post it in the chat and at the end we will have a nice surprise for you there are some new courses to be announced but there you will also find this nice course that had to start with national water I hope many alumni from national water are also here so what's the benefit of that I could reuse those course materials so the origin is the tailor-made training and I could use it then back in our master modules and nowadays I use it as blended learning so we maximize the time in class on the exercises for the alumni you know there's always not enough time for for GIS classes and of course I'm passionate about it so I want to to teach you everything and now we found a way of combining this so we do teaching the theory by the videos that people can find on eCampus and we do the practice in class we do quizzes with Kahoot and in that way we build up a very nice class and I also reuse these materials in short courses or even in tailor-made trainings because and that's my advice if you want to go this way is make your things modular so you can for different customers package the different modules and it resulted in a few new products so there's an online course which is on QGIS that's a joint venture with Newland Geo information it's a paid course so next to the open courseware but then as an added value that you can receive the official QGIS certificate and you get support and there's this nice book that Abram already mentioned QGIS for hydrological applications by Kurt Menke and myself and that's also the same course materials but then yeah compiled in a very nice book with the latest updates in it so I can recommend that nice thing for you to know is that when you buy the book my share of the book goes to a fund here hosted here at IHE to support participants from the global south to join me in QGIS hack fest and in phosphor G events because we have a lack of especially female from the global south in this open source community got some remarks on social media that are only men from Europe of my age on the pictures so I really want to make a change in that so if you buy the book you really can help with filling my fund and see some IHE participants joining this and spread the word of the open source community in the rest of the world this brings me to probably the most important slide of this webinar where we where I worked out the value chain and what we see here is on the x-axis we see the price of a product we don't really need to define that further it can also be the income for the institute or the tuition fee or whatever and on the y-axis we see the number of participants and of course with open courseware or MOOCs open educational resources the number of participants is very high this is relative and because everybody can follow it for for free so the price is zero then the next step is with similar materials we can produce a book where people just pay a fixed amount but they don't get support they don't get face-to-face experience and they don't get certificate now some people want support and a certificate so they can go for the online course we are developing now also a new online course on the same as as the book so completely for QGIS for hydrological applications where you can get support and this official certificate will be ready in a few months hopefully then some people want face-to-face training and IHE experience come to Delft and I know the alumni now get a bit of a warm feeling and we also want that many people can do that but it comes at a cost so much less people can do that and you need probably also scholarships to do that so therefore we offer our face-to-face short courses here at IHE Delft it's the same material but then face-to-face then we come at the tailor-made trainings where we can give specific parts of those materials to our target group but also develop more materials so there's again what I said before where the innovation comes in and you develop the new innovative materials and then we can use the same stuff in our MSC so all these materials feedback and that makes this model a bit circular to to the different products and again it all starts with innovation and being cutting edge I try to renew all my materials every few months that's not for every topic of course the case but it's important that we are not teaching 20 years the same material so this brings me then to the freemium model that I use then for my GIS classes so if you can see in this table is that in all the modalities open courseware online course short course and tailor-made trainings the course materials are available there's no change there's even in the free products you get that because it has no monetary value then with the online course and the short course you get a tutor for tailor-made trainings you can even choose for tailor-made online trainings which would be a great modality that we don't see much yet but it's increasing the official QGIS certificate you can get that with the online course or the short course and you can opt for it in the tailor-made trainings well etc you can read this table and you see how this works and of course the tailor-made trainings are very flexible so the impact of this business model was that I got a few new customers so many people know me from the open materials from the youtube channel from social media and this brings nice customers and I'm very happy that van Oort one of the biggest dredging companies in the world wanted QGIS training also nice to know that they use QGIS they were silver sponsor also in that time and they're sponsoring now the Dutch the first Dutch hackfest that we have for QGIS in this month in a week so I helped them to develop QGIS course materials which was more targeting offshore and was really nice for me to develop that together with them and for the food and agricultural organization we organized trainings together with E-Leave on crop mapping for the MENA region using QGIS of course and we see a big increase in short course participants and self-payers my personal target was to beat of course the non-open source GIS course of my colleague and I'm happy to say that we easily reached that target now these webinars should also not be underestimated we see now 94 participants on the screen and that's very nice I recently had one in cooperation with the Australian Water School which was a very nice opportunity we talked about QGIS for hydrological applications and yeah there after the webinar they produced this nice map with where the participants who registered come from of course much less joined but still I think we had about four to five hundred participants but we see we really covered almost the whole globe and that's your market potential and if you could have this widespread with our courses then yeah we really can increase our impact so also very important to monitor that I'll come to that later let's talk a little bit about challenges we need to be aware about intellectual property rights and clauses in contracts or letters of agreements I hashed out here some experience that I had here and which undermines our business model because if you want to do this business model that I explained you also need to get agreements with your donors and customers on what you can do with the materials and if I want to have the CC buy and see license but allow IHE ourselves to still commercialize the products then the text that is here on the screen does not help and in fact we cannot use it ourselves so in summary this text says that everything we made for this customer becomes property of the customer so you lose your intellectual property other challenges of course your organization your colleagues need to be aware of the business model of a viable business model and of course we can have in the strategy that we need to do more online but the colleagues will not move if they don't know why we do this and what the business model is so it's an incentive for your colleagues to make more e-learning if they know why and transition always needs flexibility of the organization very important you will bump into a lot of probably rules and regulations that are not promoting e-learning but go against it we know from some of our cooperation projects that a certain percentage in some universities can only be online so normally these procedures are a bit outdated and we need 21st century procedures and rules investments needed to be ahead of the market that's important so if you feel that customers can steal your intellectual property if you want to develop your course materials then you better develop it before the customer can do that so you sell the product that was already done I did that for for QGIS with with the materials around the app the input app and the merchant plugin it's a very nice tool which uses your QGIS project you can make an app that you can use in the field all for free open source and we were the first ones of course developing the materials there and you can find it on GIS opencoursware.org where all the GIS opencoursware from IHE is hosted and we hope of course that customers want trainings in that and then we can sell the experience instead of the product another challenge is we do not do enough monitoring in evaluation to measure the impact of e-learning and to confirm the business model so it's very important to have a good framework for that in place and I'm going to show you a little bit about that and what is worrying me a lot and I hope some donors will watch this webinar or later on the video is come on this is a great opportunity we need not only the orange knowledge program where many people here got scholarships from to have face-to-face trainings but we need a green knowledge program and with little money we can support a lot of people who want to learn things especially from the global south the most emails I got from my online course was that it was too expensive but the rates are very cheap for for Europe and for United States for example but I can imagine that for the global south that's very very difficult so probably using different tariffs but also providing scholarships and I think even individuals who want to support or adopt a e-learning student can just make a contribution there because that's not expensive let's have a look at the monitoring and evaluation so as said we are running our IHE open courseware now for seven years and here we see the statistics for where our customers come from and who use the open courseware so the free materials and most come from Asia and Africa so that's nice that's also very much representative for our face-to-face classes that we give but although it's accessible for the whole world we see most participants come from those places this comes from google analytics and well as a GIS person I had to modify a little bit the map because it uses the mercator projection which gives a bit of a bias towards the countries that are close to the north and the south pole and we don't want that of course then these are the statistics for the last year for this year the last 365 days and very nice to monitor that and to find out what the peaks mean thanks to our colleague Yipke from the Education Bureau we find here two peaks and this first peak was generated by the AFRI Alliance MOOC where many hopefully of you already participated in and there's a second peak here that was when I had the webinar with the Australian Water School and this generated of course a big load on our open courseware website and we hope that many people who join these webinars follow these online courses and open courseware and this is a proof that yeah it's also really a good marketing tool because you get interest in this another important 21st century skill is to use social media and e-learning is very adapted to that so you can easily link your open educational resources so open educational resources are small products like a little video of a few minutes or very short yeah materials that you want to put out there on the internet you can easily embed that in your social media tweets or put it on instagram and then you can attract a lot of potential clients and of course you hope in your business model that people will not only use the free stuff but also go to the paid products because they get added value like support and the diploma and we should also realize and we see a lot of in the discussions here with lectures that yeah we don't realize that we are now teaching to the millennials and these millennials are very different than previous generations they are used to watch short videos their tension line is much lower than the 45 minutes that we have in class so maximum five minutes which is very hard for lecturers but you have to cut it in pieces and they watch it on their phone while they're multitasking with netflix and other activities so yeah we really should fit to that lifestyle and offer our course materials in that format and it's a great opportunity for us to publish these short videos on social media on twitter and linked in and youtube even has community channels so so use that then what's in it for you as a lecturer well you get a lot of dopamine from that so I am enough motivated to make more videos if I'm not too busy with my my regular job because you get a lot of compliments on internet on your on your products so people call it here a lifesaver or the best material they've seen well that's of course what you want that's also what your employer wants to see and you can tweet about it and you see that many people yeah respond to those tweets or like it and we can get all the metrics also from twitter and that encourages us to even promote it more and yeah for this webinar I for the Australian water school I made this little video with an overview of our course offerings especially the open ones and yeah more than five and a half thousand people viewed this post on linked in that's that's also very helpful I want to come to conclusions before we go to the discussions what is very important if you are at the the moment thinking of developing e-learning is that you need to define your objectives so what is the impact you want to achieve so why do you want to do this what are your target groups what is the efficiency that you want to achieve etc things that we discussed you have to define the value chain of your course materials products and services what do you want to give for free what do you want to have paid customers for are they willing to pay and how do your colleagues look at that you need to internalize that and you have to develop the business model really take time for that because you can only get your organization so far if the business model makes sense that also means that you need to establish a monitoring and evaluation framework to see if it really works like you think it works there is in this presentation a lot of assumptions from my side and yeah we just have to measure these things and learn from you if it if it works like that then you need to do marketing also don't underestimate that you need to work on change management you will meet a lot of resistance maybe in your organization that things are not up to date your protocols are not up to date and you need to work on that together and again scholarships are needed so my great request to donors who are watching this or private people who have have money to support students we need a green knowledge program where we can support many more participants to to follow these classes even for diploma online now the surprise of the day is because we celebrate the seven years open courseware at ihc delft if you would go now to the website we have a few new courses that i want to announce today there is a new one on irrigation management and development there's a new one on delta planning and management and there's one on experimental methods which is in spanish there's an e-book and english is also available so i hope this will be very useful for you and i hope you will follow us and you'll see the new things that are posted all the time and if you have ideas then we also like to hear that from you so that's also the the last question maybe abraham can can put that up before we start the discussion is yeah what would you like to see as open courseware on our platform with this final question i would like to open the the floor for a discussion there were already some questions posted here and i give the floor to abraham maybe you can moderate this thank you for your attention thank you so much hans for that great presentation um we are going to pivot to um questions and i'll put up the first question online here on the interface here which we received by email from banmali who asks that one shortcoming of conventional educational material is language and for those of whom english is not the first language we struggle to benefit from books papers and lectures in english excuse me well this problem persists with open education or is there greater possibility of multilingual higher education with open education processes and tools yeah thank you for this very nice question maybe some of you know that i i'm also specialized in the francophone part of the world and have been doing there a lot of project work we always tried to to ask donors to and programs there to convert our english materials to french there seems not to be much interest for that from that side but we still have to put on the pressure there but in e-learning especially there's an opportunity because you can run these in parallel in multiple languages well face to face you are bound to uh yeah the majority of the group that you have in the in the class so we are working on it and maybe a nice other uh surprise for you is that we are working currently on translating the qjs materials to french with an alumnus of us he is in algeria now working on that together with me so that will become available so there's also a role that you can take up there to if you think that your target group is interested in another language of the materials we have a dopc2 program of developing e-learning materials together with our partners so you could write a proposal i'm coordinating that part so you can contact me and then i can explain you how we can proceed um i will next put up a comment by brian reid who says let me increase the font size to a more readable level one challenge is pedagogy teaching science books are fine for facts and face to face is good for developing critical thinking e-learning is is is much harder to use for deep learning says brian reid how would you respond to that um yes that is indeed a case where we have to carefully look at in the design of our e-learning um in my observation it's not always the case it depends on how you do the e-learning so with the qjs class of this year we used blended learning again and i used the book in class and i found contrary to the expectations that critical thinking was not improved because people expect when there's a lecture in the room that they get instructions and therefore i'm thinking of moving it to completely e-learning with only some contact hours where we try to work on the critical thinking so basically people figure out themselves with the tools that are available online like google and like other like papers they can read about the topic to figure out themselves how things work and then we have face to face sessions which are not about instructions but about discussion and helping each other out when there's problems with the course materials in the e-learning platforms themselves you can introduce quizzes and also the way of doing dealing with the assignments can be different so i would say yeah in gis you still have to submit a map and an explanation of what we can see on the map and a discussion maybe a report so the different ways of mixing e-learning with the traditional ways but and there's also teamwork is possible in e-learning platforms but i agree this is something of concern for the quality but not necessary that e-learning per se reduces that critical thinking the next question is from Jean-Marc it comes from twitter he asks if open education is equivalent to online what would open education processes that are not online look like interesting question i have not thought about that in my definitions and what i know it's always online because people can easily access that probably if you provide free materials on a on a dvd or as a free book a hard copy then it becomes also open education so yeah not sure what this meant here or what thoughts are about that we hope that Jean-Marc responds to us with a follow-up in course of our discussion we look forward to that question from Ujwal is excuse me i have a cough hands for your online course what is the mode of interaction with the tutor yes that's a good one there's two sides to that an online course the participant wants support probably 24 hours per day when to contact the lecturer to have help on the other hand from the lecturers side we need to budget these things we need to deal in the organization that that there's a time writing for that that i achieve we write time so how much do you allocate for your support so from the lecturers point of view you want to keep it to a minimum without disturbing the learning process of the lecture so what we do is set up frequently asked questions or forum forum on the platforms where people can read previously asked questions most of the questions i receive for qgis in the online learning are questions that are already asked i would say 99.9 percent so the answer can be easily copied from previous emails or other resources um there are modes of operation where you use a virtual classroom i personally have not yet experienced with that but i like that if i'm going more maybe with the ids students to the learning experience where they do more online where we can have some moments in virtual classrooms to discuss things there are probably more possibilities but this is what what i know of sima inga from zambia is working in the water sector in the area of hydropower planning and also in the energy sector as renewable energy co-coordinator so her the question is do you have a schedule of online lectures that are planned already so that i can share it with my colleagues in my organization yes i g delft has a page on our website if you go to education and then you will find online courses and under that you find a list um with all the descriptions and when they take place for my qgis course it's a bit different it's not in that list for some procedural reasons that we hope to solve soon but um that one also is different in the sense that it has a continuous subscription so anytime you want to subscribe you stay two months in the system but it doesn't have a fixed start and end period because i think it makes sense also to have these things more flexible for our users um the next question is from brannis law who asks if there are any courses or books on qgis implementation for freshwater biodiversity research that's an interesting map yeah not that i know of uh i i since i published my book i got in touch with some other lecturers from other institutions who also got a lot of ideas of thematic qgis recipe books uh you can understand that such a book on qgis for hydrological applications is a niche you of course are all people from the water sector but many people in the world are not so more generic qgis books like the book from kurt menke himself discovered qgis has a much wider use but i'm i'm sure that there is interest in thematic books so if you have a good proposal for that or need help then uh yeah i can always be available to co-author or review or help you with it so the next one hans is a compliment and uh you mentioned that something that keeps you going something that keeps you sort of motivated to keep uploading stuff on youtube is uh is feedback in compliments and from du du ba who says uh he's a student in environmental modeling at cz u uh thanks for dr hans's tutorials he was able to perform one of the most important tasks of his thesis which is catchment delineation for hydrological modeling yeah thank you uh du du for your for your remark i i know you already also through twitter and your questions there and you will be coming here soon for an internship so we can collaborate further so this is a nice example of people who know me from uh the open course where i use the tutorials interact through social media and uh yeah then end up at ihc doing an internship for uh yeah learning more the next uh comment is from maria who says most online seminars are advertising for a specific project without critical pro and contra knowledge exchange often no neutral overview of different methods of practices as shown how can more knowledge exchange be promoted yeah that's a good one i uh i agree with you that this should be done more so online seminars should be a two way so always should include this part where we have uh question and discussion in in this format we uh we have half an hour for that i think that's a very decent and most often it's not the case uh so that should be always a part of it i think there should always be some uh some questions like we also did today where we interact with the audience uh during online seminars and webinars there's limited limited time for that but if you have more online courses with these virtual classrooms you can have more knowledge exchange you should also do more peer learning i also hope to learn from the participants of these webinars to get new ideas there are already some questions that i have never thought of that were ever asked so there's definitely space for that but we need to provide that space and be conscious about it uh the next question is a very specific one it's from Rehoboody who asks if there are any webinars around on pc raster i don't know if i pronounced that right yeah pc raster that's a that's a good one um today a new version of pc raster came out for 4.3.0 and i was immediately thinking if i wouldn't have had this webinar today i would have a new video on how to install it um webinars on that there is also a person who was here for an internship in summer and was working on with pc raster on the thesis and yesterday told me let's make a webinar on this so it will come uh we are working out the details so uh they will be there for sure i'm increasing also the video content on pc raster on my youtube channel so i'll keep you posted uh the next question is from Khalid i'll just increase the phone size of it so we can all read it Khalid asks Khalid is from the UAE national water center and he has a question about using satellite data and processing this data such as grace and grace fo it seems a lot of research recently focuses on using grace do you think there will be courses explaining the interactive use between grace and qgis well it's a it's a question of demand and supply here for economic principle so if you would look at questions asked in my youtube channel for example you will see that many people proposed to me to make courses on topics but yeah i also have a job and a life next to my youtube channel so we cannot offer all these things that are demanded and if you see the value chain curve that i showed you before it all starts with where the resources enter the system so if there is enough demand and then i can make it if it's a hobby and if i really feel like i can do that then i would do it myself so basically requests for certain things that's also in the open source world in general that's your least chance that these things happen your higher chances to engage start the project look for resources to gather and cooperate and then we can make this okay okay i think that that we have reached the end of the excuse me again we have reached the end of the questions and comments thanks a lot hans for your great presentation and thanks to all of you for joining in for and for your great questions and comments first of all thanks hans for pointing out that i made the mistake of using the terms open education and open source education interchangeably i understand now that open source pertains to code and we should be careful about which term to use where open source open data and open education i will not attempt to summarize the discussion here in real time but i would like to share with you that my takeaway is that the education sector or to put it more plainly the process of teaching and learning is set to change in profound ways in the coming years and it is great that some of the leading educational organizations such as it apart from several others do recognize this and are spearheading this change they're trying to be part of this change rather than resisting it and i think that's very important that institutions are doing it apart from highly motivated individuals such as hans and so thanks a lot this is perhaps a good point to mention that the next webinar will be on the topic of desalination and will take place in april or july and after that there'll also be a webinar in may so please follow the following links i will just put them up in the chat box to stay updated as the topics the speakers and the timings are finalized so and also on these links you will find a recording of the webinar from today this webinar it should be up at some point tomorrow at the latest and yeah thank you all for joining in thanks hans again thank you abram and also thanks to the whole team that made this possible including maria who invited all the alumni and jipka and rakel from the education bureau and wim glas for facilitation here thank you very much for the opportunity bye
