 Good morning everybody and welcome to this workshop. The coordinators would have received a mail from Dr. Mukta Atre saying that we have a brief formal inaugural function. We have requested Professor Sukhatme, our ex-director to kindly come and inaugurate the workshop. Our director Professor Devan Khakkar will also be joining and so will be several other important heads of academic units such as mechanical engineering department, computer science engineering and also the head of center for distance education program and the head of continuing education program. We will of course have some faculty members here. You will of course be seeing all of them. We will start this formal program at 9.30. We are at about 9.7. So, I will be starting this interaction with different centers. These are not necessarily in any order, but we have selected five institutions which represent five different states of the country and these five I will be coming to in the stated order starting sharp at 9.30 onwards. Please remember that 9.30 to 9.40 is when we would like this interaction to be seen by the participants of this inaugural function who would be assembled here at 9.30 because as you know we are doing this long distance and therefore speakers here will not ordinarily be able to see you although you are all attending from 31 different remote centers. So, let me just take the names of these five colleges. Please do not feel bad about this choice. This has been drawn almost like a lottery from amongst the available colleges belonging to different states and we have chosen five because that is exactly what we will have about 10 minutes time from 9.30. The modus operandi will be the same that I will be following while interacting with other centers will briefly I will name a center will briefly go over to that center will just say hello to the coordinator would like to see the glimpse of participants who have assembled there and then we will come back and go to another center. So, this is what we will do now starting another two minutes, but before that let me read out the least of names of colleges whom we will be contacting from 9.30 onwards. The first one is SVNIT Surat which is in the state of Gujarat. The second one is Cummins College in Pune which is in state of Maharashtra. The third one is JNTU at Hyderabad. So, JNTU at Hyderabad reprinting Andhra Pradesh. The fourth one is Annai University in Chennai reprinting Tamil Nadu and the fifth one is Amal Jyothi College representing Kerala. As I said these are random choices we have of course 31 remote centers. So, between now and 9.30 I would like to quickly go over to each remote center very very briefly just to ascertain that the connection is working fine that you are able to see me and listen to my voice and similarly we are able to see you and listen to your voice. The first center is NIT Tiruchira Palli. Coordinator NIT Tiruchir. Good morning. Can you hear my voice? Yes, yes. We can hear you loud and clear. I hope our audio is very good. Thank you. Thank you. Right. So, let us go to VNIT Nagpur. Good morning. VNIT Nagpur we can see you very clearly. Can you hear me? Yes. Wonderful. Professor Gokhale nice talking to you. Yes sir. Good morning. I came just last week and then this is the first official assignment and I am very glad that we are undertaking this particular exercise during the summer month. You know it is pretty hot over here. I know it is raining in Mumbai. Mumbai you know if you would be able to send us some rains you know it would be very helpful. Well, I do not know whether thermodynamics will directly help but we can request Professor Gayathunde to try that. Thank you so much Professor Gokhale for personally participating. We will go to GH Rajasthani College Nagpur. Yeah, good morning. I can hear you and I can also see you. Good morning sir. Thank you very much. The connection seems to be good. Are you able to receive our video well? Okay sir. Thank you sir. By the way I hope that all users are aware that in case of a problem they can send a chat message and we would be able to quickly correct situation if there is any problem. Let us go over to COEP sorry College of Engineering today. Yes, Dr. Puthervi, I can hear you loud and clear. You can see several participants there. Our director Dr. Sasarudhe wants to interact with you for a minute. Good morning to all of you and it is a welcome feature that all the faculty are going to be empowered in teaching of thermodynamics you know. That is a very difficult subject for students. Well, thank you Professor Sasarudhe for personally joining us and we are happy that COEP is continuing the relationship with IIT Bombay. Thank you so much. Let us try going over to Mefko Shleng Institute at Shivakashi. I would like you to confirm sir whether you can hear me and you can see me clearly over to you. Your voice and video are good sir. Thank you so much. I recall that last December when I had come to Shivakashi to give a keynote address this is precisely the hall where I had a cup of tea with your director and other dignitaries. Sweet memories of your place. Thank you sir for participating. Very good morning Professor. This is Dr. Balakrishnan, Principal for Kapko. So nice to talk to you. The audio and the video quality are good. Thank you Professor and thank you very much for personally participating. This encourages all the participants you know to put in their best. Thank you so much. As I would like to mention it to rest of colleague participants from other places that Amruta University has been a strong partner in this endeavor and in fact the application that we are using for the audio-video interaction the AVU application has been developed by a large and dedicated team working at Amruta under the leadership of Dr. Kamal Vizlani. So I am glad to go over to Amruta. Please confirm whether you can see us and hear us. Over to you Amruta. Good morning sir. We can hear as well as see you very well. Thank you very much. Thank you so much. Let me try Walton College strongly. I can see Walton College participants. Please confirm whether you can see us and hear us. We can see you and hear you very well. I would like to just say good morning to all the participants as well as the resource persons of this course. And this is a nice initiative taken by IIT to start a course on thermodynamics. Thank you very much. Over to you sir. Thank you. And thank you Professor for participating personally. Thank you so much. With this we will halt this interaction temporarily and start the formal function in a moment. Let me request Professor Sukhatme and Professor Khakkar our director to kindly come and take the seats here. I would also request Professor Gayatonday and Professor Bandarkar the teachers of this course to join them. We will continue our interaction very briefly with the five colleges which I mentioned earlier. We will go to the Cummings College at Pune. I can see participants from Cummings College and the dignitaries are watching you. Please confirm whether you can hear us and see us. Over to you Cummings College. Yes sir. I can hear you. Good morning sir. And good morning all the dignitaries on that ice. Over to you sir. Thank you so much. The next college we go to is JNTU Hyderabad. I can see participants from JNTU Hyderabad. Likewise we would like you to confirm whether you can see us and hear us. Over to you. Good morning sir. This is Brahmara along with the coordinator Professor Vijaykumari and about 50 participants. All of us wish you good morning sir. Over to you. Thank you so much. You have 60 participants. That's a large number. Thank you so much. We will now be going over to Anay University Chennai. We are able to hear you properly. The video is also very clear. Thank you. Over to you. Thank you so much. And last but not the least we go over to Amal Jyoti College Kerala. Yes. This is Fradu Jo's the principal of Amal Jyoti College of Engineering Kanyarapali, Kerala. And all of us are here. We have got 43 participants. And the audio as well as the video clarity is excellent. We can get you very well. We can also hear you, listen to you properly. And things are fine. I hope that you also can see us and listen to what we speak. And all of our best wishes. And we are extremely happy that we can interact with IIT Bombay. And thank you very much for having taken us as the participant. Over to you sir. Thank you father. Thank you for personally gracing the occasion. And yes I confirm that we can see you absolutely clearly and we can hear you absolutely clearly. In fact this is the very purpose of using this technology that we can actually participate as if you are attending the course from IIT Bombay itself except you do not have to physically move long distance. And over the next two weeks you and your participants will find that the interaction with the resource persons at IIT Bombay is as good as if you were personally attending it in IIT. Thank you so much. So let me start this function by formally welcoming the dignitaries Chief guest, Professor Sukhatme. Thank you so much for coming here sir. Our director, Professor Devan Khakkar. Thank you Devan. Thanks for coming. Professor Gayathonde who is agreed to conduct this program for us. Jointly with his colleague, Professor Bandarkar. Thank you so much for coming. Please be seated. We have other senior colleagues here. We have Professor Sanyal, head of the computer science department under whose ages we run this program. We have Professor Tembe, head of our center for distance engineering education program. Thank you so much. And we have Professor Kannan Maudgalyan who is the Institute coordinator for all the national mission projects at IIT Bombay. We have, thank you so much for coming. You see these four people that you see here are the people who coordinate almost all of our outreach program in one way or the other, barring of course the my head who coordinates all of us to deliver a proper program. Thank you so much for coming. Before handing over the proceedings to the chief guest and to Professor Khakkar, I would just like to mention that this workshop, these workshops under the national mission project have been a dream of IIT Bombay for several years. We started doing these distance education programs almost a decade ago, but we perfected the technique over the years. We did a sort of pilot project sponsored by TIFAC and subsequently we are doing this national mission project. This project envisages that a large number of teachers across the country should have the occasion to interact with faculty members from IIT Bombay on specific subjects and that is how we have started this. This particular workshop is being attended by 850 teachers all across the country. My dream is we should have 1000 plus teachers and we have another workshop on basic electronics which Professor Dinesh Sharma is going to conduct and his colleagues starting two weeks later. We have again another set of 850 teachers participating, sorry, or 1200 and 6. So, Dinesh Sharma by conducting a program two weeks later is able to get more teachers perhaps anywhere. So, we are very happy and we are particularly happy that both Professor Khakkar and Professor Sukhatme have agreed to come here and to encourage all of us, both the participants and the teaching faculty. So, without further ado, I would request my director, Professor Devan Khakkar to say a few words. Thank you, Professor Sukhatme. Distinguished colleagues in the audience and colleagues who are with us virtually. A very warm welcome to IIT Bombay and to this workshop on homodynamics which is traditionally a very difficult course. First of all, I want to start by expressing my appreciation for this great technology. You know, this allows so many of us to come together virtually and at a low cost and I mean low cost not in just in terms of the money required for travel, but also cost in terms of time, in terms of arranging for places to stay and so forth. This is really a wonderful technology. If Professor Fatah had to organize a workshop of 850 teachers at IIT Bombay, I know that that would take at least a year of preparation and a lot of effort on all sides including the participants to come all the way here, spend two weeks away from home and so forth. So this is really a wonderful technology and I think we must explore new ways to see how this type of connectivity, how this type of computer power can be used in a big way in education. We have a huge educational ecosystem. I was told that just in Maharashtra there are 112,000 students who have joined the engineering program. That is 112,000 students have joined the engineering program in Maharashtra alone and there may be 10 million or something in the whole country. So this is a very, very huge system and any initiative that we take will be meaningless unless it can be scaled up in a big way. And I think ICT is one means by which we can scale up to address issues that affect a very large population of students. I am very happy that IIT Bombay has Professor G. Fatah who has been a pioneer in developing techniques which allow the use of ICT in education. I feel more and more of us should be involved in this effort and I think that this workshop program has been a great success and I am sure that there will be other such programs that we can think of because such types of programs can have a major impact on the kind of education that we deliver to students across the country. I would also like to thank all my colleagues from IIT Bombay for this particular course, Dr. Daitone there and Dr. Thakur for actually participating in this intensive workshop. I know it takes a lot of their effort and everyone in IIT is, you know, occupied 100% of the time so I am very happy that they have taken time off to really participate in this very important activity. Also, this is the first time I think that we are I may be wrong in this but the first time that a non-computer science course that we are dealing with and I think that is also welcome and we are taking a course that is, as I said right in the start sort of considered a difficult course in engineering. Finally, let me say a couple of words about teaching because all of us over here, many of us are teachers. In my opinion, for academics, teaching is the most important activity and really I feel that in terms of the impact that we have on the overall system, teaching undergraduates is the most important activity because of several things. One is there are more of them, only a very small fraction of postgraduate I mean undergraduates go on for postgraduate studies so we have a huge number of undergraduates and so if you just look at what impact they have on the economy and on the society when they go out I think in terms of impact, certainly an undergraduate with a good education is a great asset to the society. The second thing is that the foundations of a person's knowledge are built at that level and really I think there should be great clarity and when we teach undergraduates and in a sense we should have the best teachers teaching the youngest students because if we can build very good foundations then the rest of it is easy. I think workshops such as the one being conducted are really something by which we can address how we teach the students, how we can do a good job of teaching and in many ways I feel that to be a competent teacher is quite straightforward. One is that one must have a thorough knowledge of the subject the second is of course to be able to organize the course third is to systematically deliver the material and finally to be able to communicate with the students and I think this is something that one can learn participating in such workshops is very useful and even within IIT we have been having a lot of discussion along these lines we have actually had a retreat for two days in which our faculty are discussing among themselves how we can do this more efficiently a senate has taken this up and we have had several reports and several resolutions on how these issues can be addressed. Of course the next level is to be a great teacher and that is something that I think once you reach this platform you can aspire to and there I believe that that is something beyond all this there is some magic in it because finally a great teacher will inspire the student to learn on his own because finally learning requires effort on the part of the student and if the teacher can essentially excite the student about what they are saying and inspire the student to put in efforts to learn I think that is really at another level and that is something to aspire towards so thank you very much Professor Fatak for inviting me and I wish the participants all the best in this workshop I hope you enjoy yourselves thank you. Thank you Prasak Akkar for those very wise words I would like all the participants to note that what our director said that teaching and particularly teaching at the undergraduate level needs to be taken very seriously you would have understood how seriously IIT Bombay itself takes this undergraduate teaching we do indeed have very senior people teaching undergraduate students particularly younger students. Anyway we will continue this interaction further over the next two weeks but now I will request the chief guest of the function to come and share his thoughts with you let me briefly add a few points about Professor Sukatme he was a faculty member a colleague for what over 40 years after he retired from IIT Bombay he was given the responsibility of chairing the Atomic Energy Regulatory Board he has been an avid researcher and a great teacher and a great institution builder and of course being a mechanical engineer thermodynamics is very close to his heart so that is why when Prasagayatunde and I were discussing this course ordinarily we do not have a formal inaugural function but this time we said we would like to invite Prasukatme and when I talked to him it so happened that he was free and in fact he was keen to come and talk to you so thank you very much Prasukatme for joining us I think people would like to hear you Good morning everybody Professor Khakar Professor Phatak Professor Gayatunde Professor Bandarkar Heads of Departments Colleagues Friends It is a great pleasure to be here this morning for the inauguration of this workshop on the teaching of thermodynamics and as Deepak said, Professor Phatak said the moment he asked me I said yes for the simple reason that I have taught thermodynamics for many years and so obviously any workshop on this subject is of interest to me Now, Professor Khakar alluded to the need for such programs we are reaching out today from here I have an audience of only say 20 or 30 people but I am reaching out to 7, 800 people who are going to take part in this course and that is the technology which is enabling it the distance education this distance education is being enabled earlier the old style we used to hold summer schools in Bombay IIT Bombay under the QIP program or various other programs sponsored by the ministry we would have about 30 people come here we would have a work you know month they would stay with us and we would lecture to them on some subject or the other and they would go back and carry some way in which they could improve on their teaching that is the best we could do today with these technologies suddenly one can reach out to 800 people and that is a very big thing Now, just to give you a magnitude of Professor Khakar mentioned the magnitudes today in India the admission capacity for engineering in the country is more than 6 lakhs all the seats are not getting filled and all have not been wisely created but that is another issue the point is at least 4 or 5 lakhs are getting filled every year and mechanical engineering is probably around 25 percent of that so we are talking of about 1 lakh students joining mechanical engineering every year across the country an average class is about 60 students sometimes more but 60 is the norm which we use in so many ways in creating capacity so if you divide 1 lakh by 60 you get an idea of the magnitude of the number of students who are going to be learning thermodynamics every year at some stage of that 4 years that they spend in their college or their institute you need let us say approximately at least 1000 teachers if not more for teaching the subject of thermodynamics every year so today when we reach out to about 800 we are contributing in a substantial way towards helping these teachers to improve their skills in teaching thermodynamics whereas if I follow the old technology and I can at most reach to 30 or 50 students right here who have to come all the way here it is going to take me 20 years to do that so you can see immediately the kind of impact that we are making what is even more important is that this particular session the 10 day the 2 week program is not just about delivering lectures from here but also has with it a content of tutorials and problem sessions and in order that those be conducted well at your centers coordinators of those centers have already come here in March and spend 2 weeks with us and that is what makes this a still stronger program in trying to convey thermodynamics thermodynamics cannot just be lecture it has to be finally solving problems in fact that is true of all engineering courses you can lecture and lecture but finally students have to solve problems that of interest from the engineering viewpoint so we believe that with such programs one will make a bigger impact and it is absolutely necessary because we have created the capacity we have the students they pay a lot of money they deserve the best education at the moment what we do is when we select teachers we say well he has got a first class he looks like a good boy or a good girl he is interested in teaching take him or her and beyond that we do nothing literally nothing we expect them to learn the art of teaching on their own from colleagues or by the experience of walking into a classroom and finding out that something went right or wrong that is really what is happening you learn fast of course when you face 60 bright students all over the country you better learn fast as you run away from the business and you say teaching is no good for me you know things like that so it is very important that we have more of such programs now let me revert a little to thermodynamics as I said it is a subject to my heart graduate thermodynamics for many years to mechanical engineering students and if anybody likes if I were to use one word to describe the subject I would say it is a beautiful subject that is the objective that I would use for describing a subject like thermodynamics it is a beautiful subject for many reasons one reason is it forms the core of what we call as an engineering science course in moving up from basic science to practical engineering subjects for a mechanical engineer if he has a good grounding in thermodynamics a good grounding in fluid mechanics a good grounding in solid mechanics and dynamics and a good grounding in let us say heat transfer to some extent you can expect that he can analyze problems whether they be in design whether they be in production or whether they be in controls whatever be the areas of application in which if he does not have that good grounding he is always going to be empirical in his outlook so a good grounding in basic engineering science is the basis for being able to analyze problems in your profession and speaking of mechanical engineering one could similarly list a set of subject in say electrodynamics or in electrical engineering or in computer science and so on so there is no difficulty but that is the point basic subject basic engineering science subject forms the core and helps us to analyze and synthesize problems of interest then of course if you are creative you can do something in that subject like build new technologies and so on but the ability to analyze comes from having a good grounding in the basic core engineering science subjects of your discipline and that is why thermodynamics is a beautiful subject but there is another reason why it is beautiful you are trying to describe nature in a set of laws and those laws look terribly simple but have evolved over were evolved over years and have stood the test of time to this day first the first and second law of thermodynamics and the zeroth law it precedes it are laws which describe nature and have now stood the test of time and they are very beautiful laws very simple this is our standard question when somebody comes for admission you say tell me the first law and somebody says people say it is conservation of energy somebody says work and heat you know things like that various descriptions but basically in simple terms what the first law is saying it does not matter whether it is a work interaction it does not matter whether it is a heat interaction if I have a system whether closed or open and energy is flowing in and energy is flowing out in the form of work and heat the algebraic sum of all that will be if it is in the steady state that is all that you are saying it does not matter what it is and the second law goes a step further and that is what makes it even more beautiful it says look that is fine as far what the first law says I have no objection but there is something more which nature as nature says I can convert all of work into heat that is what Joule did when he stirred water and heated it up but I cannot convert all of heat to work that is what the second law says it is a very beautiful and a powerful statement and then in order to explain it we have introduced the concept of entropy saying entropy is a measure of disorder work is more ordered heat is less ordered and that whenever a process takes place in which we go convert heat to work and get work we are introducing order locally but on the whole in the world as a whole we are increasing the measure of disorder that is the concept of entropy and it remains still a very important concept which has stood the test of time but really one does not know whether it is the only thing that the only way to describe what is really happening why should necessarily there be such a concept which says entropy goes on increasing is not clear but it stands the test of time so we say well fine let us stick to our concept of entropy accept that disorder is going on increasing somebody says to what extent can it increase I do not know that is what makes thermodynamics a beautiful subject there are things still which need exploring things of a philosophical nature which also need exploring but on the practical side as an engineer thermodynamics is much more all our problems of energy power plants everywhere are all problems in which we are analyzing energy and trying to get the best out of those power plants so that we can get as much work out of heat as possible we stop worrying at that point that we are increasing the overall disorder in the world and things like that it is happening let it happen right now I want work from that heat how efficiently can I do it and that is the last part of what we teach in engineering thermodynamics that is trying to see what are our power conversion cycles and what are our refrigeration cycles so as I said it is a very practical subject it is a philosophical subject and it is a subject in which you really understand that how well I have people have ended up describing what nature is given us and that is what I said a very interesting subject now let me come to the last part of what I want to talk about briefly and that is one can talk about a subject to a teacher and say look thermodynamics is this and this and this but if you want to be a teacher if you want to face a class of 60 every day finally you have to enjoy what you are doing the business of teaching is a difficult one people say I can teach fine everyone can teach but the business of doing good teaching is an art which you have to develop and cultivate over the years it never finishes even on the day of your retirement you cannot walk into a class and say I know everything about teaching there is no such thing you are all the time learning so teaching is something you have to enjoy that is the first thing I would say to all those who are listening to me across the country if you enjoy your job that is the first step towards doing it well the second thing which I want to talk about teaching and which is maybe old fashioned because I am getting old many people of course use modern technologies I am surrounded with gadgets just now as you can see monitors and things like that but ultimately in teaching a subject like engineering thermodynamics there is really no substitute for having finally a teacher with 60 students in front and having a blackboard and maybe chalks of 2 or 3 colors there is really no substitute for it you may have power point in which you may use for showing say there is a difficult sketch to draw or a difficult figure you do not want to take up the time to draw it on the board or it is difficult to draw you may use some projection technique where you have to show a video or some process taking place or something like that but when it say let us say comes to explaining or deriving a law there is very little that can substitute deriving it on the board with a chalk there is very little substitute for it and in that process students learn in a manner in which it stays imprinted on their mind suppose to come back again to thermodynamics I had to teach the first law and to derive an expression for the first law for an open system or a control volume whatever you call it and this will be done in this class when you go along you can straight away on a power point say this is the expression and say this stands for this first term stands for this second term stands for this third term and so on that is your expression nothing wrong you have stated on the board you will never do that on the board you will draw a system an open system let us say there is a fluid flowing into this space A B and you say this fluid is flowing in with a velocity V the area of this is A and then you ask somebody in the class what is the rate at which fluid is flowing in and the person will say rho A V say fine then you ask the next person but he has made some assumptions in saying rho A V what are those assumptions and maybe he will answer it maybe it does not matter you say well he has made two assumptions he has assumed that rho is a constant he has assumed that V is a constant across that area A I now say to you it is not a constant both are varying across that area A so what will be the expression he will immediately say if he knows a little bit of calculus he will say put an integral outside the integral dA that is the rate at which mass is flowing in through that area and now if you have said this in the class those students if they have got it will never ever forget it in their life if you write it on the board straight away rate at which flow is going in is rho A V dV and then you say if rho is a constant take it outside the integral they may or may not quite grasp the importance of what you have done so I am saying a board using a board well is an important part of teaching and that can only be done on a blackboard with this class which is interacting with you a little cannot interact too much otherwise you cannot cover too much material during your one hour so you need recourse to modern techniques I am not saying do not use power point some power point is needed from time to time some what you call projections of videos are needed from time to time but there is very little substitute for using a good using a board systematically by the way by systematic what do I mean let us say the board consists of three panels you start in the left hand panel go down straight finish that go to the next panel but do not erase the first one because there are students who may want to write something from it when you go to the second go to the third then go back again to the first and I learned this the hard way I can tell you after joining IIT Bombay when I attended after I joined in 65 we had a very senior professor in mechanical engineering professor and you know I he used to teach thermodynamics also incidentally and I said to him I would like to attend your class I hope you do not mind you said of course not please come and so I attended his class and the first thing that struck me immediately was how systematically I use the board he used the board because I appreciated that you would go down systematically the second thing which I appreciated about him was how many sketches he would draw on the board my teaching thermodynamics he said you have to picture the situation first you have to draw a sketch then only put down equation he did not believe much in equation being an old time person so later on the roles were reversed where I taught he transfer he attended my classes and he said fine whatever you teach is excellent but you know every time you draw an integral sign I am reminded of a snake that is all things like that so we were on in different let us say generations but the fact is I had I picked up that wisdom how to use a board by attending his class and I still remember that so the point I am trying to say basically is in this course we will cover of course thermodynamics very carefully the teachers are outstanding teachers who are going to be covering this course for you so you will get all the fundamentals but ultimately if you are going to face an audience of students develop a love for the students develop a love for teaching you will enjoy it the students will enjoy it and then teaching becomes a wonderful profession in which you are proud to be going out every day and saying I am doing something that is worthwhile for you for your students and for the nation so I thank you very much for inviting me this morning it's been a great pleasure and with these words let me say I have great pleasure in inaugurating this workshop on the teaching of thermodynamics thank you very much thank you Prasukatmay for those very encouraging and nice words in fact now I understand why many of your past students still remember you for thermodynamics I wish I was taught like that I studied thermodynamics at Indore and it never occurred to us at that time that it would be a beautiful subject but now I understand better I hope all of you heard him very carefully when he emphasized the importance of teaching and the systematic methodology that you must adapt I would like to add and all the participants and also to Prasukatmay that we indeed understood the fact that only power point is not going to be very useful so in all our long distance teaching programs we have a gadget which is an equivalent of a board which is this writing pack and in fact I believe Prasar Gaitonde rather prefers to use that than just the power points so do we in fact I was an avid user of power point but when I was teaching my programming course I found out that a pre-written program does not appeal to the students as much as development of that program so I learnt it from a colleague of mine Prasar Rana from Maths department was using a tablet PC to write and I have since adopted that and I find the teaching has become far more effective so I entirely agree with Prasukatmay that a teacher must use the conventional wisdom of interacting with students encouraging them to think and giving them picturizable visible sort of artifacts to think about and develop the derivations rather than show completely derived things I would also like you to remember the most important thing which he said is that if I want to be a good teacher I must enjoy teaching there is no substitute for doing anything well without enjoying it and I think that is the message that you will carry with you so thank you very much Prasukatmay for giving us these wise words I would also like to thank Professor Khakkar the director of IIT Bombay or for that matter director of any institution is an extremely busy person but you could see that he emphasized exactly the same point and he did mention that this kind of programs can reach out to large number of people which was endorsed also by Prasukatmay let me tell you that the first that we are doing would not have gotten off the ground if successive directors of the institution had not supported all our early experiments in fact when we started it I remember Prasukatmay was the director then and we had put some very costly visa equipment subsequently when Prasukatmay joined as the director he encouraged it and in fact extended our distance education program to a full-fledged center which my colleague Prasukatmay now leads Center for Distance Engineering Education Program so thank you very much Prasukatmay for joining us I will not thank Prasukatmay and Prasukatmay that is a job I would like to do the valedictory and in fact some of you at least the co-edators have interacted with both my colleagues here but let me tell you that in terms of being systematic and in terms of being passionate both of them are no less particularly Prasukatmay whom I know for well over 35 years incidentally he happens to be one of the favorite cellars of Prasukatmay so there is every reason to believe that he has imbibed the systematic development of courses and much of the passion for teaching from him I think we are in good hands let me also take this opportunity to thank several functionaries of the institution without which this kind of programs would not have happened the two most important people are the co-ordinators for our continuing education program Prasukatmay and co-ordinator for our Center for Distance Engineering let me tell you that the conventional wisdom in continuing education program is that you conduct workshops for 30 or 40 teachers and to endorse a conduct of 850 teachers program is not very simple or straightforward particularly when those teachers are not physically here but our CEP establishment went two steps forward to say this is perfectly fine they in fact help us conduct the co-ordinators workshops which have to be held specifically in IIT which as Prasukatmay said is a precursor to every such workshop that we do Prasukatmay of course makes all the facilities of the center available to us for all interaction in fact the hall from which this function is being conducted is the major seminar hall for Center for Distance Engineering Education program a project like this cannot be conducted because all projects sponsored projects of the government or any other agency project they are all conducted in IIT Bombay under the ages of a department this particular program is being conducted under the department of computer science engineering and let me tell you computer science department is currently undergoing a lot of problems our new building is not yet ready we are all working in a compressed mode making space available for any kind of activity is difficult the primary demands on the space are always from our research labs it is to the credit of my head Professor Sanyal and to all my colleagues in the department that in spite of the space crunch for last 2 years they have been very very considerate in giving last space for this mission project you might only see a few teachers talking to you but let me tell you that there are about 50 project engineers working on several technology developments like clicker or the AV related development and other things there are several managers and supports of which are working and is almost like a very large entity itself all of that entity can function very comfortably in the ages of CS department and I would like to thank Professor Sanyal and my colleagues for that I must also thank all the other faculty colleagues who have come here to grace this occasion I hope more of you would come forward in coming years to conduct these workshops I am taking the point made both by Professor Khakkar and Professor Sukhatmay that these programs indeed are able to help make an impact on the general teaching ethos of the engineering subjects in the country and I promise you sir that will continue this good work the government of India in fact wants to expand this to not just the core courses in engineering but even other elective courses and other things in specific areas which will probably appear in the next plan I would like to thank my own team members as I said there are 50 people the technical people are not here of course they are always in the background the technology that they develop they develop is what we and I use but they are led by my managers the video team is led by Mr. Sajjan Kumar Dixit then we have our three senior admin managers Dr. Mukta Atre most of the coordinators and in fact many of the participants would know because they would have interacted with her that is Mukta for you Mrs. Kalpana Kannan Kalpana is sitting at the other end yes so she is another manager and of course our finance minister Jaya she handles all the finances it is not easy to interact with 31 remote centers getting their functions settling their bills and in all the work that she and her colleagues do we are very able to help by an extremely efficient office of our dean RND Professor Rangan Banerjee unfortunately could not come here today I had invited him but I would like to express my thanks to him and his office for all the support that we get with this I would like to conclude this inaugural function I will personally be talking to you I have been kindly and graciously given a slot of half an hour by Professor Gayathound day on Saturday before lunch so this Saturday before lunch I will be engaging with you where I will tell you more about the spirit of this workshop and what we want how we want to take this further I just wanted to make one announcement I think Professor Gayathound has already put his first test on the Moodle so after the tea break this is the typical IIT style you are learning by solving problems so in the typical IIT style we will be doing that there is also an additional questionnaire you see we want to measure the effectiveness of this effort and this effectiveness can only be measured by seeing how much impact the teachers who participate in these workshops make on the learning of the students whom they teach later so this we have evolved a methodology and MTech student is working on that where we will begin by collecting feedback from the students whom we have taught in the past collecting feedback from you now collecting feedback from you after the workshop and collecting feedback from you and your students in the future so long run process we are just beginning to do that but the first feedback that we would like to collect is from the 850 participating teachers before they start the workshop to assess in their own mind what is the state of preparedness and what is the state of their experience in teaching this course so please remember that before the course becomes old just as you will answer professor Gayathondhe's technical quiz I would request you earnestly to answer those 9 questions it will not take more than 6 or 7 minutes that is in the moodle over and out thank you very much
