 Okay, so I also I've just been to make a video but my main message is the video should be Much low barrier everybody should do it all faculty should do it all students should do it And we shouldn't treat the video as like we always have to make a Hollywood star movie The video should be just like playing piano. We should always practice video This is because I think a video recording our student work is the best way to think to to see Their thought process I analyze the problem about my meaning in the home to find universal Tennessee I shut up. Okay, okay This is my main message. I Have taught I was trained about physics I thought in computer science and biology are missing my data science course So I in all my course I require students to use video for their to complete their assignment Either it's the genetics microbiology Computational biology data science Java Python algorithm. So I used to do this. I give a lecture Talk about principle. Oh, this is not moving. Oh I gave lecture talk about the principle then go over data analysis. This is me doing this But Isn't and then I thought if I ask the student to do this Maybe at least the student tutor will work better and that the other student look at a another student tutor It's become also more persuasive. So this is actually a student doing this This actually doing in class so most all my video are doing live But some of them But this one is recorded alive in class So I do this and this is student doing this and the effect The student connect much better to their peers than to my video and also the help student going over the process There are also many advantage of doing this especially with this online education when student finish it The homework if they have a problem, how do I help the student and the students can send me their video recording? And I look at the screen that the video I can Circle where the problem is and tell the student. That's your problem And this is another example. This is actually Java coding problem And I look at the video you found out. It's not about Java. It's actually about Windows Windows had problem. So yeah, it's a very effective way for me to solve the student problem especially with with Now with you might in my Current colleague many in the student actually have to work and they often have to take the class remotely And the common tool I use is the YouTube live stream. I know this is a if you Google Open source free screencast software. You will get the top 10 and plus many others. So And this just something I Can do this lie to show how easy it is. So this is often do this in class Like a new event and then we can just say In line now Okay, ready to go I block my camera. So you won't see me But you can actually I just share the screen share my entire deck screen Present to everyone. Oh, by the way, that's recursion. That's my my example to show student the recursion lens that Casting there. So and then if I turn back You can actually see that it is recording and those are some student examples this is the algorithm bucket sorting and this is the genetics and student working through the Pedigree explain the probability of a child having a disease And that's the well our data and as you are they show this. This is the UNIX Exercise student actually in this case using Xcd. San Diego high-performance computing class to I'll just This is Yeah, this is this actually down one with the still as a speleman and that's a golden cluster from San Diego. So This is probably my best word Opportunity, I think using video in data science education is a challenging and opportunity And I never had to do it and faculty PhD should also do it And we actually have a set of Data grant to support faculty to do this and this year we have two computing boot camp That's the link for application and I'll stop here. Thank you
