Which is a team member from our group that partners with schools and districts and press, to get communications out to parents and that is Dan. Dan are you there? There's Dan! And he's gonna help us out, try to answer our questions together. He's also going to be looking at the message boards on the various social media channels that this is being streamed out to. To try to surface up the questions that might be useful for as many people as possible. Just to get everyone up to speed on what this is, especially if this is your first time, Khan Academy is a not for profit with a mission of providing a free world-class education for anyone, anywhere. For many years we've been building resources for students both in the classroom and outside of the classroom. Resources for teachers inside the classroom. For parents so that they could learn all the core or most of the core academic skills from starting with Pre-K with Khan Academy Kids, going into elementary level Mathematics, English and Language Arts. We just launched some English and Language Arts content going into middle school then high school, Math, Science, Humanities. And even things like free SAT practice that we've partnered with the college board. And when the school closure situation became a reality, we realized it's our duty to step up even more. And so we've been trying to create more and more supports for teachers, parents, and students, to navigate this crisis. Last week we released things like daily schedules for students of different ages. But think about how can you put all of these resources from Khan Academy and resources from other players together into a very coherent schedule that can be something that bridges us until schools reopen. We've been doing webinars with teachers and parents to get them up and running. And we've been doing this. This live stream which we're calling a homeroom. Which is away for all of us really to feel connected, answer each other's questions. It's a way for us to get feedback and ideas from all of you. Actually we are now with our three kids at home and I told my wife some of the ideas about we just gotta stick through it. Well one of the home school parents told me that on our homeroom live stream. So it's just a way for all of us to feel connected in a time of social distancing. A little bit of community interstitial tissue as people work on their various, their various resources. And so with that I encourage you, students, parents and teachers, put your questions, your comments, your ideas on the message board below, wherever you're seeing this. Whether it is on Facebook. Whether it is on YouTube or Twitter. And we, Dan and I are going to get to 'em and try to answer them. And I'll start with a few quick ones. See this is from Sonya, "Sal will you be making anymore meditation videos, maybe one for parents and for teachers? I need these now more than ever. You could even read the phone book." Well that's very generous that you'd be willing to listen to me read the phone book. I think you would get tired of that. But no that's a good catalyst and I would love to do that. For those of y'all who don't know, I've gotten serious about meditation over the last couple of years and you know meditation can evoke different images in a lot of people's minds. A lot of people view it as a spiritual thing or a religious thing, but here we're just talking about it in the most general possible way which is just a tool kit to help for us to become aware of our thoughts to help still our minds. For coping with some of what many of us are going through right now. And you know the first meditations we put out this is actually only a few weeks ago. Were student meditations for dealing with things like stress and procrastination. Many of y'all know that stress and anxiety were already at record highs for a lot of especially high school and college students. Especially when it comes to test taking. And so we wanted to help with that. But this is a great idea Sonya. I think we'd wanna do that. Let's see. We have Leo, says the question, "In a unit test or course challenge, are they more difficult than other questions?" Good question, Leo. So today, the way Khan Academy works is, when you do an exercise, the exercise might ask you to do five questions, it's actually coming from a pool of 20 or 30 questions. And so and whether you're doing an exercise, a unit test, or a quiz, it's coming from various pools of questions. When you're doing unit tests you're doing multiple skills. So let's say a unit test has 15 questions in, or 10 questions in it, it will then be sampling from a pool of 300 questions. It is possible that you see questions that you have seen in the skill-focus practice or the quizzes, or if you're taking a core challenge, in the unit task, but it's unlikely, in fact, it's very unlikely that you're getting a complete repeats. And we've been doing a lot of analytics on this. We think that the units tasks and core challenge are actually very indicative of where you currently are in your journey. We are exploring things like making specialized unit tests and core challenges that can only be accessed in that way. But we're thinking about whether that will, whether that will actually be significantly better than what is there, but that's the current thing that you have. Questions from Dan, I think Dan's got some stuff to share with us. - Hi, thanks, Sal. So, we have a great question from Shala Karimi, apologies if I pronounce the name. "I (mumbles), do you have any recommendations on easy chapter books?" - I don't have recommendations on easy chapter books, but we have published resources in our daily schedules for students. So if you go to, you can just go to khanacademy.org, there's a link to access the daily schedules. If you're looking for easy chapter books, I'm assuming that this would be probably for elementary school aged students who you wanna get ramped up reading in chapter books. We have a link to a reading list from experts on this subject for different grade levels. And so I would got to that schedule, click on that reading list on the part where we talk about reading practice, and then you're gonna see a list of great easy chapter books. One thing I recently found out from another parent over the weekend, my wife told me about this, is that it sounds like Audible, that's the part of Amazon that has books on, I guess, audio, that they've opened up their kid section for free. So I would also look at the kid section on Audible. I think you'll get some really cool books that your children can fall asleep to, or might even be fun to, everyone sit around the couch and listen to it together. So those are my two starters to get you started on the chapter books. - Sal, I would add the team's actually putting together a reading list and hopefully, we're hoping to get that out next week as well, broken up by age group and everything, so. - Awesome, yeah, so you can use those resources we have linked to, obviously, Audible is audio versions of it, and as Dan just mentioned, we're gonna make even clearer reading lists by grade level in literally coming days. - Question, Sal, from Mathematics C, and this is really important one. "Why are getting questions wrong so important?" - So, getting questions wrong, and obviously, you don't wanna get a question wrong if you can get it right, it's not like that's gonna do you any good. But, a lot of times when you do anything in life, whether it's math or free throws, anything, when you fail, we oftentimes kind of beat up on ourselves, sometimes get discouraged, it hits our ego a little bit, our pride. I'm like, aw, maybe I don't need to do this thing, and you're oftentimes tempted to disengage. And the thing to remember is, that those times that you've failed, you're kind of discovering your edge. And it's when you operate in your edge that you're going to grow the most. And so there's even been research studies that when people fail at something, let's say a cognitive task like a math question, but then they reflect why they failed, why they got it wrong and how they could've done it differently, that's actually when you form (mumbles). Those of you who are familiar with things like weightlifting oftentimes you'll hear people say, oh, you should do some reps until failure. Failure is a good thing, it shows that you've had a real workout. Sometimes failure has been stigmatized because you're like, oh, if I fail a test, that's bad, I got an F, or if I got a bad grade, or if I get questions on a test, and then it reflects on me. And that's why at Khan Academy, I just described how our items are created. We wanna give you as many chances as possible to show that you can become proficient in a concept. And so, it's not that when you do it once, you got 80%, you got 20% wrong, all of a sudden you're just labeled 80% student forever. You can keep going at it. This idea generally speaking is called mastery learning, it predates Khan Academy. Many advocacy studies showing that it can accelerate folks' learning. It was just hard to implement, historically, if you didn't have some tools that can have almost an infinite number of questions give you immediate feedback, and be able to personalize the individual student's pace. But that's why failure, when you fail on a question that you can kind of engage in, you should reflect. That's when your brain growing the most, and you just have to reflect on why you got it wrong. And then you're gonna, you're gonna your growth will only accelerate. Dan, more questions? - Questions, yep, we have a question from Rebecca Dullah who ask, "Will there be more classes using Disney and Pixar resources?" They're one of the more popular ones on our site. - Yes, so for those of you who aren't aware of what Rebecca is referring to, we've had a partnership with Disney/Pixar, I think with launched it about five or six years ago where the Pixar team in particular said, hey, wouldn't it be cool if we could help expose students to how math, storytelling, and other things are part of the movie creating process. And so we have this thing on Khan Academy called Pixar in a Box. And you can view it as an enrichment, but you can see how coding, how math, how writing are essential for creating some of the movies that we all know and love today. Rebecca, to answer your question, so we have Pixar in a Box, we don't have any plans right now for any new content like that, but definitely, keep us posted. What are the things you like about Pixar in a Box? What are the things you want more of? And obviously, we can always consider possibilities. - So Sal, we have a question, it's pretty relevant with school closures happening all over the world. TJ (mumbles) asks, will Khan Academy try to accommodate other countries' different subjects? - So, great question, TJ. The simple answer is, yes, to a certain degree. I just had a interaction with our team in India. We actually have a decent size team, by our standards, about 14 people in India. And I was asking them how they're responding to school closures there. And they've been doing very similar things to what we've been doing in the U.S., publishing schedules, being able to do more supports for teacher, parents, and students. And so those are obviously linked into Khan Academy India. There's also a fully Spanish version of Khan Academy, es.khanacademy.org that is used in much of the Spanish speaking world. I think this is a good push. Everything is so fluid, for all I know, the team might have already done it, but a lot of the resources we have in English we wanna make sure that they're gonna be available in Spanish as well. So that will serve a lot of the Spanish speaking world. With the same in Brazilian Portuguese, we have a lot of usage in Brazil. We have 40 informal translation projects around the world in other languages. And so I look forward to coordinating with all of these, what we call, our language advocates and see how we can get similar resources in those geographies. They're gonna be, in certain languages, we only have things like math vocalized in other geographies like in Spanish speaking Latin America, we have much more localized. But that's a really good push, TJ. - Yeah, I would add that our content in Brazil is also standards aligned, it's aligned to the BNCC standards. So we're covered not just in the U.S. So Sal, we have a great question from Yen Bow who asks, this is gonna be a question that pops up frequently, "How can I not be distracted? What's the optimal amount of time to study for a given subject?" - That's a good question, and I'm always asking it myself. You know, there's an interesting, we had a researcher, I believe we published the video that came to our office about a year and a half ago. And she's pioneered something called the, which I, she spreads word about what's called the Pomodoro Technique. It's called that because it's based on a, it was started by someone using a timer in the shape of a Pomodoro tomato. And the Pomodoro Technique is, is give yourself a fixed amount of time, let's call it 20 minutes is what a lot of people talk about, and you get to set a timer, obviously, it doesn't have to be a timer in the shape of a Pomodoro tomato. But a timer, you can do it on your phone, you can do it on a computer for 20 minutes. And say, okay, for this 20 minutes, I am going to do focused work on whatever I need to work on. And then, after you're done, set the timer again for 10 or 15 minutes to give yourself a break. And actually force the break. Sometimes after 20 minutes you feel like, oh, I can keep going, I'm in the zone, so to speak. And obviously, if you're really in the zone, you don't need to stop, but by knowing that you have that break, it actually makes that 20 minutes a lot more focused, and a lot more productive. I know sometimes when I have large blocks of time and it's unstructured, I kind of can easily procrastinate, find things to delay with. But then all of a sudden if I say, oh wait, wait, I have a mtg in 30 minutes, let me finish this right before, then I can be very focused. So that's kind of in line of the Pomodoro Technique. I think on top of that, especially with things like school closures and social distancing, the more that you can find a dedicated part of a desk that you associate with doing work, you only do work there, ideally, if you have enough space, it's quiet, etc., that would be a great addition as well. But I think it's, make a list of the things you need to do, have a schedule, we've obviously published some schedules, adapt them to your needs, and then set that timer and say, okay, this is my moment, I'm gonna do this. When you do it, create a little check list. It'll get a little dopamine hit with the neurotransmitter that makes you happy when you get that sense of accomplishment. Then give yourself that break, that's important. Especially in times of social distancing, try to get a little physical exercise. If you can go outside, go outside. Go for your walk with the social distance norms. And then you come back and you'll be that much more energized to have another 20 minute session. - So Sal, we have a Math and Science teacher, Samir Mijar and he asks, "How can Khan Academy be helpful to me as I teach my students?" - Well, that's a big question, Samir. If we were talking pre Covid-19, and what I'm saying is still true with Covid-19, and hopefully post Covid-19, our whole focus was to support teachers like you. And every teacher we talk to talked about the scenario that they get students at a certain grade level, every student has different gaps. Some of them are ready for the material, some of them need to remediate the concepts from before grade level, some of them are ready to move ahead, and if you're just one teacher in a classroom of 25, 30, 35 students, it's very hard to address the particular needs of each of them. You know, and at school it's taught that differentiation is great a practice, but in practice, it's actually very hard to do it when you don't have proper supports. And so, at Khan Academy, one of our propositions or values to teachers are that we wanna be that teaching assistant for you. We want to help you differentiate. And so the way that this has worked in classrooms is that for 20% of class time at least, and we see lot of good advocacy studies around it, teachers have students working at their own time and pace on Khan Academy, and as they do so, teachers get data on what kids are working on, what are they mastered, what are they not, who's engaged, who's not? And that is actual data that teachers can use to break students out into more focus groups. If they see a bunch of students having trouble in negative numbers, okay, let me take those five aside, the other can continue to work. Then they go back in and continue working at their own pace. Let me now work with the kids who are having trouble with decimals. So that is the framework that we think could work very well in Math and Science class. If you're serving a group of students who have significant gaps, many of them are behind grade level. I've been talking about Tim Vanderberg a lot, who is a amazing teacher in Hesperia, California. Ninety percent of his students show up in his classroom below grade level. He actually does two things, he simultaneously works with the students to learn at their own time and pace at their grade level unit, and at the same time he tells all of his students, these are sixth grade students, to start as early as early-learning and a third grade math an arithmetic on Khan Academy and do that at their own time and pace as well so that they can fill in all these Swiss cheese gaps that might have accumulated over time. In this Covid-19 world, everything I just described is still operable, and those schedules we've published talk about how it could work for students of different age groups as they're now not being able to work from school. And as a teacher, I think, one of the powers is you can continue to monitor that data from your home, see what the students are working on, where they're strong, where they're not, what they need help in. And if you see that, wow, I still have five or six of my kids who are really struggling with this concept, then you could schedule a video conference with them. You could say, hey, why doesn't everyone come on, you know, if you're using some kind of a learning management system, say Google Classroom, you can see here's a link to Zoom for you five, I'm gonna assign this to you five students, please join me at 2pm Eastern time, making things up, we're gonna do a focus session on negative numbers 'cause I'm assuming you've already used, you've looked at the hints on Khan Academy, you've looked at the videos and you're still having trouble, I wanna work with you. And then you could schedule another for other kids. And then maybe you can have whole class video conferencing to say, okay, we'll see how everyone's working. What can I do, get feedback from some students to unblock them more. So I think that whole world of things are things that could be very powerful in this now distributive remote world that we find ourselves in. Other question- - Sal, we have a question. We have a question from Jaylon McCann, it's actually one that I wanna know too. "Do you have all the Black Hole Badges?" - It's amazing how much people are into Black Hole Badges. So simple answer is, for those of you who don't know what a Black Hole Badge is or don't even know about badging, we have badges on Khan Academy for various accomplishments. And the highest badge is a Black Hole Badge. And we always wanted to make that for really exceptional things. Now, one of the things that happened, this was about seven or eight years ago at Khan Academy, I would go and answer people's questions when they asked them in our discussion boards. And people didn't believe that it was me. And so we needed some way to give evidence to people that that account was actually my account. And so what we did was we gave me a Black Hole Badge called a This Is Sal Black Hole Badge. And I think then the engineer who did that, he just was trying to maybe butter me up and he gave me a couple of more Black Hole Badges. And so I am one of the few people who has a Black Hole Badge. I believe there are others and there's in different times in history different ways to address it, but given how many questions I get about Black Hole Badges from students, I do think all of us at Khan Academy have a duty to you to be clear about what it takes to achieve one and how you can get there 'cause it seems like that is motivating for a lot of folks. - Great, thanks Sal. We have a question from another teacher, Charlene Seuss, Our students at Khan Academy use MAPPERS for Math, love it, is there a plan for Khan Academy to do this with reading?" - That's a great question. So for those who all, who don't know what that is there's something called the MAP Growth Assessment that's taken by 20% of grades three through 8th students in the United States. And it measures student growth which is a really powerful thing. In fact, most of the advocacy studies that we use to measure Khan Academy advocacy, we use the MAP Growth Assessment. They're run by this non-profit called the NWEA. And they really are the gold standard in growth. And so the MAPPER was actually a very simple, it was actually a (mumbles) project from some of our team members a couple of years ago to be able to say, hey, if a student is scoring in this range on the MAP what might be appropriate for them to work on Khan Academy? Done since then is we've actually reached out to the NWEA and we formed a partnership with them. And what we're rolling out which is a more (mumbles) where it's actually integrated with the MAP Assessment. And that's something that we're doing with districts. And so for any of you teachers out there what happens is students take the MAP Assessment and it automatically populates personalized learning plans on Khan Academy, we call it the MAP Accelerator on Khan Academy. Teachers can adjust it. We really pride ourselves in our ability to give teachers (mumbles) 'cause they know the students best. But then students can work at their own time and pace. And then when they take the next MAP Assessment, the growth that's measured, we can then start to see, hopefully, associations between the time on Khan Academy and the growth on the MAP. So the MAP acts for placement on Khan Academy for personalization and then that work on Khan Academy we can see how much it drives student growth. And so that is something, this is a new muscle we're building for Khan Academy. We're doing it officially with the districts so if that's something of interest to folks, I encourage you to talk to your school principal, the district's superintendent and say, hey, we should think about doing this MAP Accelerator. And the reason why it's a district thing is there's technical things like rostering, and making sure that the student IDs all work throughout the district so that it syncs well with things like the MAP Assessment. The question is are we going to go into English and Language Arts? So the simple answer is, we don't have plans on MAPPERS to do that, but MAP Accelerator we do have plans and I hope that that will be available in the next several years to answer your question. Other questions. - So Sal we have one more question before we have to close out today. So this one's from Lucas Muldrop. What do you think Khan Academy's biggest weakness is right now? - Our biggest weakness. So I'm very aware, I could go through a huge list. I think there's a couple, we definitely have gaps in certain subjects and grades. And people on this that I've talked about we have Khan Academy Kids which is reading, writing, social (mumbles) learning and math. The core of math we have from Pre-K all the way through Calculus and Statistics. English and Language Arts is a new muscle that we are building. And there's only certain aspects of it that we can tackle with the modalities that have on Khan Academy. We have what's called the beta version which is almost a pre-release version of our English and Language Arts. It has reading comprehension passages, students can answer questions, but it still doesn't have all of the mastery of mechanics yet. Obviously, we haven't figured out ways to give students writing practice per se at those grade levels, so that's a gap. I think we need to figure out middle school Science. We have a gap there. I've recommended that a lot of middle school students can work on high school biology right now 'cause it's very relevant to the world and I think they have the background to do it, to start learning about viruses and RNA and DNA. And I think in high school we actually have many more subjects, Math, Science and Humanities. I think there's more to add. I think another gap that I think is super important is we are building tools that the students can learn at their own time and pace. We can give data to students, to parents and teachers. But we don't view that as a substitute for the live in-person interaction as you heard from the previous teacher's question, Samir's question. The ideal is that this is used in conjunction with a live teacher or a parent, or if a student is stuck, they can get motivated to keep engaging, power through those failures which are really powerful learning experiences. Teachers can take 'em into breakout sessions. And we were seeing a lot of success with that in physical classrooms during, you know, what you could call blended environments where kids are working on Khan Academy and they're able to get either peer to peer help or help from their teachers. I think in this time of school shutdowns and the Covid-19 situations, I think that in-person interaction is even more important because we're all socially distant, but obviously we can't be in the same room together. And so that's why in our calendar and on this live stream rather than saying, it'd be amazing if teachers and parents and students could create viewer conferencing sessions in parallel to the Khan Academy sessions to be able to do some of that live in-person interaction. So I think that's a weakness for Khan Academy. I think it can be complemented with other things. I think there's many other weakness I could get into the detail of the product. Our team here, we have a big list of stuff that we hope to tackle over the next few years. And actually that's a good segue for me to just kind of close out. In my closeout, first of all, thanks everyone for joining, as I said, in all of our live streams. I think this is now the 6th, 7th one that we've been doing. I hope you're finding this useful. I actually find this incredibly satisfying to stay connected with folks in a world where we are socially distanced and if this can help people feel more connected, that's a huge, huge thing. And we are doing everything on our side that's possible to be able to step up to this crisis. We're seeing our server cap... our load had up more than 2X. So things like our costs are going up, and I just wanna remind everyone we are a not for profit organization, we are funded through philanthropic donations. Many of the gaps, the weaknesses we just talked about on Khan Academy, these are things we would love to fill, but we need resources to do it. We need donations from folks across the board to make this a possibility. We've gotten incredible support from some corporate partners. If any of you are parents working, distribute it, try to get your corporations involved with us. Folks, Bank of America was the first to step up last weekend followed closely by AT&T, Google.org, and then most recently, well I'll announce it tomorrow. I'm not sure if it's public yet. But that's just kind of a, that's helping a lot and we need more corporations. But our costs, our servers were millions of dollars before the crisis and now they're going to be double that. On the order of it was $6,000,000 a year on just server costs alone much less we have a team of 200 folks who are helping develop the content, writing the software, partnering with school districts, etc. etc. So our costs are going up and this crisis and we need your help. We're running a significant deficit that we're not sure how long we can do it. So anyway, thanks everyone for being a part to this. I will also close out with stay safe, stay socially distanced, I'm gonna work on those meditation videos 'cause I think the most important thing is take care of yourself right now and then that's going to put you in a position where you can start thinking about how you can take of others. Thank you so much, thanks for joining.
