This is a live stream that we started doing every day since school closure started happening 'cause we realize as a not for profit with a mission of free world class education for anyone anywhere, we have a role to step up. It's our duty to step up to support teachers, parents, and students as we all navigate through this crisis. And so we've been trying to put as many supports out as possible teacher webinars, parent webinars, (mumbles) class schedules, frameworks for learning plans for students, and also this homeroom. And this is a way to stay connected in times of social distancing and to just talk about interesting things. Many of which might be related to the crisis or whatever else is on folks' mind. I do like to remind folks as I just did, that we are not for profit and we can only exist through philanthropic donations. So if you're in a position to do so please think about donating, we were running at a deficit even before the crisis and now we're seeing about two and a half to three times the traffic we normally see, and you could imagine that plus all of the other programs and content we're trying to accelerate are only making our costs go up higher. I do wanna give a special thanks to several corporate partners that stepped up over the last couple of weeks when they realized how big the need was to support everyone on the education front for COVID. Special thanks to Bank of America, Google.org, Fastly, AT&T and Novartis. They've made a huge difference, but we still are running at a deficit. So any more help from either corporations or individuals is very, very much appreciated. So with that we'll get into the heart of this live stream and sometimes we have guests and sometimes we don't or I guess you could say today I am the guest. And so we could treat this livestream as really just a ask Sal anything so you can get on the Facebook and YouTube message boards and literally ask me anything and I have team members that are helping me surface interesting questions. But we also said that given that this is the end of Teacher Appreciation Week that we wanna make sure teachers feel supported especially as they're all trying to navigate this world of distance learning or making videos. And so I'm also happy to answer questions for teachers who are wondering what are tips we might have for making content, for making videos and what are the tools we have? So feel free to put those questions in. I already have a question from Facebook Jay is asking, "I must admit that I would be happy if I just knew the name of the tablet that Sal uses to present. That is the biggest challenge when teaching remotely. I cannot tell you how many times teachers have said, if only we had tablets like Sal uses." All right I will tell you the name of the tablet I actually have it right over here, and I'm not normally about product endorsement. So I'm not sure if this is the best tablet out there or what but it's definitely met my needs. So let's see this is the Intuos Pro Medium Pen Tablet. I think it costs 100 or $200, it looks like this, and it will come with a pen that... Whoops I'm pressing buttons on it, I hope (mumbles)... It comes with a pen that looks like this. This camera is kind of a reverse mode. So there you go. So that is the tablet and I think the cost really increases as you go from the small, to the medium, to the large. For many years at Khan Academy I had the small version, which was I think was $70, and you can go pretty far with that. So yeah hopefully that is useful and obviously this is useful. Tablets like this are useful for making Khan Academy style videos. And I actually use a tablet like that with a pen and I use Camtasia to record my screen and this is the microphone that I have. This is a Samson... And once again, I'm sure there's other good microphones let's see Samson CO3U, I just realized it wouldn't make do much good if I'm reading the model number when my mouth is on the other side of the microphone. But just with that and Camtasia you can make exactly the types of videos I make. And obviously, this is useful for all of y'all who are also doing live, Zoom or Google Hangout type sessions as well 'cause you can share your screen and then use your art program. Oh, and I use SketchBook Pro for the art program, but you could use others. I like to just use something that's quite responsive. Some of the art programs that get super fancy there's a little bit of a lag and that bothers me. So that's what I try to do, and I've been working with some teachers running some live sessions as well. And so I use the exact same tools for that where I can share my screen and share the art program. I will say a low tech hack for the live sessions, and actually in theory you could do this for your videos as well, is those those small whiteboards that we have students do their problem on, you can literally just have one of those and write with a with a marker. I've actually found that to be reasonably good especially for the kind of the live sessions when you're trying to work with students. So from YouTube Matthew Masters asks, "Sal, do you think there will always be a place for classroom learning or will online learning eventually become the standard?" Simple answer is yes I think there will always be a place for classroom learning, or I hope there will always be a place for classroom learning. Especially for students who haven't reached adulthood. So I would say for K through 12 for sure, because in theory yes students could learn a lot of the academic skills potentially on their own time and pace, on things like Khan Academy, and or you can have Zoom sessions and you can have this kind of distance type of learning, but that's only part of what really makes the school experience powerful. There is a whole other level of having incredible teacher mentors, being able to form bonds with them, being able to do extracurricular activities, all of the socialization that goes on in school, knowing how to work in groups, knowing when to communicate, when not to communicate, know how to get your point across. These are all super important skills that you'll never see on any standardized test, but we all know that they're very, very important for overall life and success. So, I've always said If I had to pick between an amazing teacher and amazing technology I would pick the amazing teacher every time and I would prefer to have that amazing teacher in person, so we should definitely strive for that. And I think I would want it for my own children and frankly all children. And so I think the interesting question over the COVID crisis is, how do we get as close to that as possible given the constraints that we have of social distancing? And then longer term, hopefully when we get out of this crisis sooner than later. How do we leverage the best of both worlds? So I think hopefully we're gonna go back to school, kids are gonna be to get that socialization, they're gonna be back in those classrooms with their amazing teachers, but then everyone has built a stronger muscle for sometimes maybe the distance learning does work maybe over summers, maybe over breaks, maybe after school. It doesn't have to just be between the teachers and the students, it could be older students and younger students or it could be the peers working together, so I think that would be a good takeaway from this whole process. I think higher education, there are some real questions. I loved my college experience, I loved sitting in the dorm and pontificating about philosophical questions and I met my wife and many of my best friends in college. So I definitely think that was a very valuable experience, but there's a lot of students who, there's huge trade offs. They need to help support their families, they might want you to start make money while they're in college, and so I think in cases like that when just you have more of adult learners, I think there will always be a place for the in person college experience. But I can imagine some adult learners decide that that's not for them and that they could still get their college degree and learn all the material, but do it at their own time and pace and be a little bit more flexible because maybe they hold a job or they have to support their family and things like that. So, my personal view is I hope we only double down on the physical experience but leverage some of the tools we're all exploring with a little bit more as well. So from Facebook, Jaya Gupta asks, "How can I become a good teacher? Because I'm teaching my students, but some students are not taking it seriously. Please tell me dear sir, what to do." Jaya, I won't pretend like I have all of the answers. And I in the Khan Academy journey I've done a certain flavor of teaching, but there's a whole other dimension of teaching which you and many other amazing teachers are doing on a day to day basis that I think I can learn a ton from y'all versus the other way around. My best advice, though, is try to make it as interactive as possible, and when you do that think about it. And this actually goes to the earlier question about in person versus digital. I think there'll always be a place for in person, but we should always be conscientious of what maybe digital, or online, or software, or videos could do. So, if you're just giving a lecture for 10 minutes straight in theory, that could happen over a video. And so if that could happen over video then maybe it should happen over video, but then that liberates you to do something else. And it's not like all of a sudden there's nothing to do, you could have a Socratic dialogue, you could have a simulation, you could have a project, you could put a problem up on the board that's a little bit more challenging and have the students struggle with it a little bit. Have them break into groups and try to come up with their own answers, and then present it and you're walking around nudging them, giving them a little hint for the ones that get stuck. So I think there's a huge opportunity for that classroom to just interact with more with each other. Those students that you might be describing whose eyes are glazed over a little bit, I generally think if you told that student, "Hey, pair up with the person next to you or form a group of three or four, here's a puzzle, here's an interesting challenge, here's a philosophical question."
