 I am Guru Swamy Devanath, I work as associate professor at BVRT Hyderabad College of Engineering for Women, which is located at Hyderabad, India, and my talk is on effective teaching and learning methodologies by using open source. This is all about engineering education, especially, you know, I work in women's college, so my talk is about what are the effective teaching practices which we can do by open source. The majority of the speakers, they will be talking about different kinds of things, but I have gone through the list of speakers, but, you know, teaching methodologies by open source, I hope I am the one here. So, you know, if you go to Google and just search teaching and learning methodologies, you get n number of things. There are many methodologies to make the learning more effective. As the previous speaker said, as we are dealing with generation jet, so you know, I sometimes feel ADHD is present in them or so, something like that, you know, because you know, I was sharing with my cousin brother also, so they will be chatting from the town of the bench. So, I will be telling them hands on the bench when you listen to my lecture. So, they have to keep their hands like this, so listen to my lecture. So, that's what, you know, the Facebook, the WhatsApp, the Insta, what all, you know, there are many diversions from them. So, it's a challenge for the teacher nowadays, so how to make the class more effective, how to make the knowledge you know, imparted into their minds some or the other way. So, as the previous session, the question being asked are the students, are the kids do, do they want to go to engineering field? So, the answer was, majority of them do not want to go to engineering field. So, the same thing here, they are not interested to study engineering and, but still, you know, we have to motivate them to make it more effective. So, there are many technologies, there are many methodologies to be there. So, I have chosen a very primitive one or, you know, very, you know, everyone knows about it, which is called as mind mapping. So, mind mapping is the one which makes, you know, which, which works with the cognitive technologies of the human being and makes the things more clear. So, I have, of all the methodologies, I took mind mapping because it's most prominent. So, and why I have taken mind mapping because, so these are the advantages which I thought about it. So, it makes the learning more effective. It makes, you know, people remember it forever. So, it is a very clear, it gives the clear picture actually. And it gives an easy understanding of the concepts. There is no confusion or ambiguity when you go there. And also, you know, this mind mapping is in a pictorial form. It's not like word or text where, you know, you have to remember. And, you know, there is a strong impact whenever someone goes through a mind map. It's just like a, you know, how you pass through MRT. Like, my cousin was helping me how to go to MRT, whether it is blue color, red color, purple color, yellow color, something. Was not even looking at the words present there, whether it is a small words also. So, that's why the pictorial view are, you know, it's so colorful. And the other one is, they don't forget the knowledge. As the year passes by, they forget the subjects and the content in it. So, here, you know, we are, we want to retain the knowledge for a long time. So, this was helping me, many, you know, I felt this to be very interesting. So, here are a few pictures of my students who were doing mind mapping, but it is all in a manual way. You can see different pictures of the same concept. I teach electrical substitutes and electrical network TV. So, when I tell to them, I taught the subjects and I was giving an assignment. Like, you know, do mind mapping for what all you do. So, there is no uniform format. They just used to, you know, it's a free hand drawing. Like, they just used to draw like that. You can see different pictures of all the students and they feel happy for what all they have done. It's a partial learning. I felt like I can't say it, no for them. This is right or wrong. I can't say it to them because, you know, again, Gen Z actually, Generation Z. So, where they feel annoyed and they get disappointed and they say, I don't like your subject. I don't want to study it anymore. So, I say everything to be right, but I want to correct them in a better way. So, this is what, you know, this is what happened before I attended last year for 2017, for Asia Summit. So, you know, this is all the picture. You can see the total class has developed. You know, you can see how much happy they are. The total 66 students approximately have drawn their own mind maps and they want to showcase it. And it has proven to be prominent actually. I'll show the results also at the end of this session. And you know, this is all, you know, handmade drawing, you know, and there is no final judgment like this one is right and this one is wrong. So, I used to say everything is right though, you know, they didn't project it properly. I used to say it to be good, excellent, better, or something like that. So, I attended FOSS Asia 2007 and I thought as mind mapping is working very well with that subject and that students. So, can I use some open source technology with that. So, that was the small thought which I got in year 2017 when I attended exactly one year back of FOSS Asia. So, immediately I know it's a coincidence. So, our college, we have something which we are proud of that is called as Vedic Vishnu Educational Development and Innovation Center. So, where teachers are trained on different kinds of education technologies. So, we are being trained on scientific educational practices and where I was the trainer for many teachers in different learning methodologies and teaching methodologies including the working of the brain and all those things. So, we had a center. So, that center afforded training. It afforded training on using softwares that open source for, you know, mind mapping. So, this Vishnu Educational Development Center, it works with the faculty, it works with the students. It doesn't teach you anything about technology. It makes them things much effective. Suppose a person wants to pursue his research. It tells like how to do the research, what kind of peer review journals we have and you know how to start the research, what is the way to search in the internet and stuff. Along with that the students, it motivates, they are some personality development trainers who make the true students to set their goals and to be more motivated towards their life and you know plan their career. So, that's a kind of institute which is called as Veldip which is located in Hyderabad. So, we literally go one week there. We forward all our families and we keep on working 24 by 7. We work on projects. We learn new things. All the teachers there, you know the teaching has totally changed in India. It's not like chat and talk kind of thing. So, every in a one week class we have a session for activity. So, we don't want the students to get bored. Just like speaking, speaking and you know bombarding with information. So, these are all things which we learnt at Veldip at our college. So, finally these are the two open sources which I worked on. So, I was being trained on these two things. One is Explined and Freemind. They are completely open source software where you know you can develop mind map for any kind of things. So, you know I really worked like I was really working on it for days together and made many mind maps. So, if you go if you work with the syllabus here. So, this is what the university, our own university called Jawaharlal Nehru Technological University. I just took this picture from the syllabus copy. So, you know this is the subject which I am going to teach. If you look at the unit one Magnetic Substance. So, it is all in the centers which this generation students never are interested to read. So, this is all in this form. So, I may I use mind mapping. So, when I use mind mapping it is all into this form. So, might be this Magnetic Substance what that you have to read which which what is how they are being divided is the basic classification. And if you go more details how you are going to work on problems on it what kind at which particular part you get the problems. Which particular part you have the classification which particular part you have the differentiation between two components. These are the things which totally the theory part this is all in the form of a sentence which my students never want to look into. So, I made them into this. So, I can say that this is the you know a full-clutch model. So, with that you know that students can just go through each topic and find out whether he know the topic or not. And he practice the problems based on the topic or not. So, that is what this Magnetic Substance is a small topic. You can see the you can see this one it is hardly two lines in the syllabus described by the Java Learning to Technological University. But you go more in detail it has very much long to study very much huge concepts to study. And on top of it this is another subject which I worked on as you know this is called as Network 3D. And this one was developed by X-Mind Software. Where I have used different colors and you know different kinds of arrows it is not all in a straight line. So, that you know they just pass through it and understand it much better. This is what done by you know X-Mind Software. And here is another subject called Network 3D. And every electrical engineer fundamental unit is three phase circuits. All of us talk about phase and line, line and line, line and neutral kind of thing. So, this is a basic three phase circuits which is a foundation for electrical students. Unless they do not understand this subject they cannot pass through all the three years of their engineering. Because you know it all talks about voltages, line voltages, phase voltages, line current, phase current. The relationship between them what is the three phase power and all those things. So, this is all concept here. You can see hardly three to four lines is the syllabus described by J&JU. But this is the mind mapping which was developed by free mind. So, I developed free mind and every student you can see the subheadings also. So, whether it is what is the introduction, whether it is a balanced star connection, balanced delta connection. And the other part comes like unbalanced delta connection, unbalanced star connection with 3Y. So, what are the things he has to say unbalanced star connection with 4Y. What are the concept he has to say and after that what is how do I calculate the power in three phase system whether by 3 watt meter method, 2 watt meter method or by a single watt meter method. So, this makes the clear classification of the complete unit rather than just reading through the text and you know being doubtful whether I got the full subject or the concepts or not. So, that is what you know mind map has made things much easier. So, not only about TV. So, this is all I have just show you this for an example, but I have developed mind maps for all the 5 units. Every unit has 2 sub you know 2 sub parts. So, every part I have developed the mind map. Now, I will go this I felt this mind map to be interesting and immediately you know I have developed something for the lab also. So, lab you know the list of the experiment should be like this. So, after the list of experiment this is again electrical circuits lab and you know this is the procedure generally we have a manual for every experiment and in the manual it is all like substitute diagram table column aim operators again procedure. When a student comes to the lab we ask him what is the procedure. So, when he talks about the procedure he say connect dash for the substitute and he is he is not clear like what he has to be done. So, when this is a screen shot from the lab manual. So, these are there are two experiments each experiment first experiment has 5 step and the next experiment has 4 steps. So, I am talking about the first experiment this is how he has to do it is just a mind map where instead of going from one end to the other end it is just like you know what you have to do the superposition theorem first what is the set. So, if you want to send up something it is being not included in the box and I think for those actually. So, when I develop this people were telling like it looks like a flow chart, but it is not a flow chart there is no decision making here there is no start button stop button they are just series of you know steps which has to be done in the experiment. So, they just go through it it is not being one sentence complete they are just being instructions given here. So, you know this is the longest experiment I can tell you and after that there is another experiment called maximum power transfer theorem which is considered to be the difficult experiment in all the substitutes lab. So, it is being made simple like you know you do not have to go with all the steps and you know it is which is not clear just go to go through this mind map and you read the final conclusion like what you have to do. So, it is all about electrical substitutes lab and you know there is another lab called machines lab which is the hard for electrical engineering students. So, this is all the syllabus you know which we work with huge machines and you know it is terrific for the beginners. So, because you know the start of starts coming down currently and there will be noise like they will be shouting like anything. So, here these are the list of experiments which are prescribed by J.M. to you. I have just taken one example you know separation of losses separation of losses in a DC machine is the experiment. So, if you go with the procedure this is the kind of procedure we have. So, there are series of experiment. So, and you know this is the way you know the mind map has clearly explained like what it has to be done. So, this is this is what it has to be done I will just show you yeah I will just show you one video after theory. So, I have taken a feedback from one of my student like the what she wants to do. That is the audio come up. I will play it again. Yeah. Yeah. So, one of my student I asked her feedback about the theory network theory part like how did you feel about mind mapping. This is her response actually. I will play it. Can you hear it all of you. So, this is so this is one of my student you know after teaching her through mind maps. I was asking her what is your feedback how do you feel. So, she felt these in a way to methods you know help her in knowing the concepts. So, now I talk I was talking about electrical machines lab. So, this is the experiments which are prescribed by J.M. to you and you know when you provide them manual these are the steps which are given to them like they are continuous steps you know students never want to read huge sentences or lines you know they want something you know in a pictorial view or short sentences you know hardly. So, that you know when someone asks what is the procedure to do the experiment they can go through this and they can just tell out or whenever they perform the experiment they can happily tell out like this is the way we have to do the experiment. So, this is all done by the experience software. Yes, I will just play this one. Hi guys, previously we used to have many theories and procedures in our lab. So, yeah, yeah right this is what the thing you know after talking about this one you know about the lab I have a hint taken the feedback. So, the student responded in a better way and you know the students have responded in a better way you know they go for the examination, university examination and they take up the you know they do the extra examination. You know I taught it the question paper will be set by another one else and a paper evaluation will be done by someone else. So, no I don't know who has character my students paper. So, the subject which I taught is network theory you can see 66 students have attempted it and you know total 66 students have passed in it and have attained 100 percent result. So, because you know I felt you know this I asked them what is the thing you know because I provided you material I provided you videos I we solved problems in the class what made you more effective then they were telling the mind maps which you made which you showed us has shown has given has been more effective that's what the thing which they showed okay I'll show a small video okay I'll just show you another video actually. I have been taking feedback from many students actually so in order to know how people felt it. So, I was taking another girls video also so this is what you know finally yeah. So, this is how the mind mapping has been working more effective with the students. So, with that I want to say thank you to all of you. Thank you. Yes. Yes. Yes. Yeah, we can develop games of such kind but you know the total attention get diverted again in the class you know they don't concentrate on the technical part you know the game becomes more dominant than learning. Yeah. I was kind of thinking you could show the program since you go through the course you can show the places of the subject that you completed. Yes. Yes, it can be done once the course has been completed we can even do it. Yes. My impression is that it's good because you need to learn the material but they also need to learn the skill of being able to read a written procedure and follow it step by step. Yes. Depending where they go I mean they need to be able to learn that concentration and follow it. Yes, yes. You know it's all continuation to the previous speaker's question like generation you know G. So, you know they don't pay more attention to read the steps yeah the first step they read but when they come back to the third step they are not interested to go for the fourth or the fifth step actually. So, this is all if you can look at it it's all in the line might not be a complete sentence it's all like three fourth of a sentence which is colorful and which says go for the next one what should be done between the two steps. So, it's all making them more attractive kind of thing. So, just like passing the text like this is 1 2 3 4 5. So, we are not giving numbers we are telling like this is the heading and this is the these are the things which has to be there and what are the steps to be done one after the other that's how you know we are not making that you know reading have it totally zero we still have to make them to read or else it would be difficult for them to write a record or you know mark down in the observation notes. Yes, yeah when they draw their own mind map it's all like they have their own creativity. So, you know something might miss and they feel like that's the only right one. So, the teacher has to finally judge which is the best one. So, it's better the teacher write a mind map of his own and make like that is the standard one and he compare with other mind maps. Yes. Thank you all. Thank you very much.
