  • - Hello everyone, it looks like we are live

  • and we're getting better at starting on time.

  • Thanks for joining us at our lot daily live stream

  • at our new time that we started yesterday

  • now today at 12 Pacific through Eastern

  • and many people are from joining from all over the world.

  • We're calling this a bit of a homeroom,

  • because obviously in this time of school closures

  • and social distancing, people can use

  • things like Khan Academy at their own time and pace,

  • but I think we all crave

  • a little bit of social connection

  • and a way to to realize that

  • what we're going through,

  • the whole world is going through

  • and as as troubling is the scenario we are in,

  • as a civilization there's the silver lining is

  • we I think in some strange way feel more connected

  • and one real you know humanity

  • is one group of people right now.

  • So just for those of you all this is the first time

  • that you're attending one of these live streams

  • with this home homeroom that we do every day,

  • it's really a catch-all for answering questions,

  • getting announcements out there.

  • Really just like homeroom in real classrooms.

  • And it's not just for students, it's for parents,

  • it's for teachers, it's for anyone else

  • who has questions of any form.

  • Just to get everyone up to speed

  • on what the resources that are already out there

  • from Khan Academy,

  • obviously for over a decade

  • we've been building resources

  • that start you as early as pre-k our Khan Academy kids app

  • the it's suitable for students as young as three

  • all the way up through the first grade,

  • Common Core Standards up through six year olds

  • and then on the main Khan Academy app or website

  • you can for sure get math from kindergarten

  • all the way through middle school,

  • high school and the core of college

  • and also sciences at the high school level,

  • some humanities at the high school level

  • and we just launched what we call a beta,

  • which is almost like a pre-release

  • of English and language arts for grades 2 through 8.

  • We also have free SAT practice which is a partnership

  • with a college board that's in reading,

  • math and writing.

  • And we also have topics like economics and others

  • that I mean I could I could keep going on about.

  • So those resources were always all there

  • but as soon as we realized

  • that the school closure situation was happening

  • a few weeks ago,

  • we we realized we have to step up more,

  • we have to provide more resources.

  • So that's when we started the livestreams,

  • we've been running teacher and parent webinars

  • to help teachers and parents understand

  • what resources there are and how to get started.

  • We have also published a schedule,

  • a little over a week ago

  • that for students of different age groups,

  • what could be an indicative schedule for them,

  • how you can structure their day

  • leveraging resources from Khan Academy

  • and other resources including

  • you know dance videos on YouTube for your PE

  • or you might want to go outside and run around

  • or there might be some form of reading lists.

  • This week some of you all realize

  • we just did it a couple hours ago.

  • We are also experimenting with doing academic webinars.

  • So a few hours ago we ran our first one

  • which was on algebra and we focused on the topic

  • of systems of equations

  • and we had great you know we had a thousand students

  • participating and we're taking the video

  • and we're gonna put it on our YouTube channel

  • and probably promote on social media as well.

  • So you'll at least see a recording of it

  • and I hope many of you have a chance

  • to join some of these future classes.

  • So with that one thing I want to say

  • you know where we're trying to put out

  • all of these resources, but one question

  • that we're getting from a lot of parents is,

  • they're just feeling a little bit overwhelmed right now,

  • how do they focus on things,

  • you know are they doing a disservice to their children

  • if if they don't have everything

  • all figured out just yet.

  • And the one thing I want to make very clear to you is

  • no one has it all figured out just yet.

  • Even in my own house you know

  • I've figured out some what for especially my older kids

  • but my five-year-old we're figuring it out

  • but it is getting day day by day better.

  • And so I think the important thing

  • to appreciate as a parent,

  • there's a lot of things going on right now,

  • you're working from home,

  • a lot of people in this situation

  • where even they might not be able to work now

  • and then you have to there's childcare as an issue.

  • And so keep it simple,

  • especially in the first week or two

  • it's not the end of the world,

  • if things are a little bit less structured,

  • if your kids if you're just having

  • quality time with your kids

  • or just whatever it takes to get through the day.

  • But I think as as we go on,

  • try to just make sure that the kids get

  • a little bit of a reading every day,

  • a little bit of math every day.

  • We have suggestions obviously Khan Academy as a resource

  • for both and there's reading lists

  • for the on the reading side of things,

  • you know if your kids are old enough

  • encourage them to journal.

  • And then over time you could try to layer on more things,

  • try to do more and more of the types of schedules

  • we've published, those schedules are not meant to be rigid.

  • They are meant to be evolving documents.

  • We are evolving them and you can adapt them

  • to your own needs.

  • But this session we wanna make it

  • as interactive as possible.

  • So I encourage everyone, if you're on Facebook,

  • YouTube, Twitter start putting your questions in

  • and we have a team of Khan Academy folks,

  • we're gonna be looking at them

  • and surfacing the questions,

  • it looks like a lot of people are thinking about.

  • I also wanna introduce my colleague Dan too,

  • who's kind of co-hosting this livestream today

  • and we're gonna actually this is fun

  • 'cause we figured out the technology

  • hopefully over the coming livestreams

  • we'll be able to bring different guests in

  • and people who can help out with this,

  • but Dan's gonna help he's in contact with the team

  • that is surfacing the questions.

  • So please please send send in your questions.

  • I'll start with one I see Stacy Wilber from facebook says,

  • can you please put in an adult program

  • so adults can get their diplomas please.

  • Stacy that's one of the dreams of Khan Academy.

  • We don't issue things like diplomas

  • but I do we do know a lot of stories

  • about especially adults leveraging Khan Academy

  • to prepare for things like their GED

  • or their you know whatever graduate

  • requirements for high school diplomas they might have.

  • So that's where we could support you right now.

  • But it is a dream to one day be able to connect

  • to work on Khan Academy

  • to you know real life economic or academic outcomes.

  • And Dan feel free to jump in.

  • I see another question from Facebook Shahla Karimi,

  • says Salaam, I have fifth grade first grade

  • and something younger daughters,

  • why when it's a little typo,

  • they are all acting out

  • and they are really emotional

  • since they are home due to virus.

  • How can I help them?

  • Well shala that's a great question.

  • I think right now there's probably

  • about a billion parents who are experiencing

  • some version of what you're experiencing including myself.

  • So I think the first thing to realize

  • is don't don't beat up on yourself

  • and think it's just like you're the only person

  • who maybe you know your kids are acting out.

  • And especially you know if they have to stay at home,

  • and they're not getting

  • as much social interaction as possible.

  • I'm not a child psychology expert,

  • I actually hope we can bring some in

  • into these livestreams, all I can tell you is

  • try to leverage things like video conferencing,

  • if you have access to it

  • so that they can connect with their friends.

  • We've been doing playdates at home,

  • obviously with my youngest who's five years old.

  • We've been moderating his his playdates

  • with some of his five-year-old friends

  • which can get a little chaotic

  • if you don't help them out a little bit,

  • we've been ensuring that you know

  • in this time of social distance

  • you can still take walks and still have exercise outside,

  • you just have to keep distance from other people.

  • But we're we're being quite religious

  • about making sure that we go outside

  • at least twice a day if we can even if it's raining.

  • We're getting the umbrellas out

  • and saying we're going for a walk.

  • 'Cause I think it's really valuable to get that.

  • And then I think what we're seeing in our own household

  • is still a little bit interesting sometimes

  • but just everyone is getting

  • a little bit used to this new normal

  • which is obviously suboptimal normal,

  • but I think things will get better.

  • We've had a homeschooling parent in the past say,

  • just try to stick with it,

  • it does get better, the kids will get used to it.

  • Obviously the suboptimal situation for everyone.

  • But the number one thing is also take care of yourself.

  • Don't get so overwhelmed.

  • 'Cause obviously the more as parents we get overwhelmed

  • and we'll snap at our children

  • and then everyone will get stressed out.

  • So the more that you can kind of keep calm,

  • whatever it does to get you know,

  • whatever you do in your life

  • to get to that meditative state,

  • give yourself some alone time

  • so that you'll have that emotional reserve

  • to to deal with where the kids might

  • the supports they might need.

  • Fazlu from YouTube, Faizal Kabirin

  • if I'm reading it correctly.

  • This is a crucial moment of coronavirus,

  • how can a student from Bangladesh

  • continue his studies online?

  • Okay, so it looks like Fazul is from Bangladesh.

  • Thanks for joining us, I think a little late there.

  • So you know depending on your level of hussle,

  • I think the the key is

  • is that you actually you could view

  • this as a glass-half-full scenario

  • where a lot of the demands on your time,

  • especially for younger students

  • they might have had a lot of social engagements

  • and other extracurricular activities or homework,

  • a lot of those have been loosened

  • and so a place that Khan Academy is a great place

  • to focus on those subjects

  • that you really wanna make sure

  • you have a strong foundation in,

  • the high school subjects, early college subjects,

  • biology, chemistry, physics, economics

  • there's other things off-site

  • you know if you've graduated outside of Khan Academy,

  • you can move on to things like MOOCs

  • and take more advanced courses at a university level.

  • I think it's a great time to take on projects

  • where it's one thing to learn a lot of academic things

  • but can you apply it, can you create

  • you know can you know create invent something

  • that can solve problems for folks right,

  • make a software application that can do something.

  • So I think there's a lot of opportunities

  • but I think that's the best way

  • to be constructively occupied right now.

  • And obviously there might be opportunities to volunteer

  • for people in your community

  • who might need help.

  • If you're a young person,

  • you are you should you have to

  • you should be still socially distanced

  • but you might be able to help older people

  • who might have trouble leaving their houses

  • and have to be even more social distance

  • you know with things like getting groceries,

  • or honestly just connecting with them.

  • You know keep distance and say hello

  • or send them a text message

  • or just make sure they feel socially connected.

  • - Couple questions that are related.

  • Questions from our students

  • currently needing help to schedule their study times.

  • So from YouTube Adnan APUs Kench Walla

  • as well as Sephripicin are asking

  • one how should they plan their study schedule

  • and two if you have any tricks

  • to organize their time.

  • - So you know I don't know what age group you're in

  • but one of the tricks is we have released these schedules

  • that I talked about,

  • if you just go to Khan Academy at all

  • you'll see several links that say,

  • daily schedules you click on that.

  • I'm assuming y'all are maybe high school aged students.

  • But there's their schedules essentially

  • for every age bucket high school, middle school,

  • elementary school and early learners.

  • That's a good starting point,

  • there's nothing rigid about those

  • you can copy and paste it and modify it to your own needs,

  • but what I would advise is

  • to have some form of a schedule

  • and make sure your schedule gives you time

  • to rest and relax.

  • I think you know there's two extremes

  • that people could fall into right now

  • and it's completely fine to not have

  • your act together in this first or second week,

  • but you know there could be the extreme

  • where there's no structure

  • and you're kind of just wandering through your days,

  • that doesn't feel healthy to me,

  • after many days or weeks of that,

  • you'll I think feel and a little bit more blah so to speak.

  • And then the other extreme we're like

  • oh I got a study you know 18 hours a day and all that

  • and that's going that is also unhealthy.

  • So what I recommend is you could use our schedules

  • or create your own but schedules that cover

  • all the important basics,

  • make sure there's time for gaps

  • don't just try to power through those gaps,

  • I think especially now we need those gaps

  • even more than ever and that try to you know get front-load

  • the work of your day,

  • that's actually you know how I try to do my life

  • and then by early afternoon

  • say okay I've done what I need to do to the day,

  • I can give myself a break

  • and I can you know entertain myself watch TV,

  • or work on a project that I really care about,

  • I can do a little bit of video conferencing with friends

  • and you know there's always this question

  • about FaceTime screen time

  • and I think there's good and there's bad screen time

  • and actually even with sometimes bad screen time is okay.

  • Now that we we're finding more time at home

  • but the good screen time is or the better screen time

  • is especially for an older student

  • is your time learning, your time creating, writing

  • coding and I think it's a valuable time

  • to get on a videoconference zoom

  • or a Google meet or hangout or Skype FaceTime with friends

  • and and I encourage you,

  • you know don't just try to go a little bit deeper,

  • talk to your friends about what

  • what are you really thinking about,

  • what are they stressed about,

  • what are they anxious about

  • and remind your friends that you're here to support them

  • 'cause I think we all need to hear that right now.

  • - Quick question for you,

  • it's related to our OSP product

  • we have a young YouTube person,

  • Sokina Benny, who wants to prepare for the SAT exam

  • and doesn't know how to start.

  • - Yeah kina well that we have a very good answer for,

  • for those of you who don't know College Board

  • who though the folks who administer the SAT

  • another nonprofit they reached out to us

  • about five or six years ago

  • and said we wanna address the inequity around test prep,

  • we wanna partner with Khan Academy

  • to make the world's best test prep

  • that happens to be free.

  • And so we launched that about five years ago

  • and it's being used by a majority of students

  • who take the SAT and it's in math, reading

  • and actually writing as well.

  • You can write things to SAT prompts and get feedback on it.

  • And so I think Nina was the name if I heard correctly,

  • but what I encourage you to do

  • is go to that official free SAT practice

  • on Khan Academy you can navigate on Khan Academy

  • or just do a web search SAT practice Khan Academy

  • you'll find it and you get started

  • and try to spend equal amounts of time in math,

  • reading, math and reading especially

  • and also time on writing.

  • What we've seen in the data

  • is the best practices for students are

  • make sure you are working on skills

  • that are pushing you forward

  • and you're not just trying to do easy things.

  • Oh there you go very good.

  • We're getting better at this technology all the time.

  • Try to peer you know follow the recommendations.

  • The recommendations we actually the software

  • in partnership with the SAT folks,

  • it knows which concepts are most important

  • for not just for the SAT but also for college readiness

  • and also it knows where your weak spots are.

  • So as you answer more and more questions,

  • it will know your strengths and your weaknesses.

  • And so it's trying to give you the suggestions

  • that are optimal for you to learn as much as possible.

  • If you've taken the PSAT,

  • you can actually link your PSAT scores with Khan Academy

  • and if you do that, your PSAT data

  • will inform the software even more

  • what your strengths and weaknesses are.

  • So I would go there and I know we have,

  • you know the next SCT administration got canceled

  • but it will come back I am sure at some point

  • and so I think this is a great opportunity

  • to spend some time every day.

  • We even have it in some of our schedules,

  • even if you're able to put

  • 30 or 40 minutes a day that's great.

  • And I would say at least once a week

  • try to take a full-length practice test.

  • We're seeing that is also a best practice

  • that helps a lot of students.

  • And when you take that practice test,

  • try to take it in as most realistic circumstances as you can

  • so yes, spend some time on our official SAT practice.

  • Let's see you have a question from Debby Charlton,

  • says thank you for all you have been doing

  • to help teachers to use Khan more during this time

  • as an ambassador I've been doing conference calls

  • to help teachers get set up and move forward,

  • the items created have been a huge help to many.

  • Oh well thanks Debbie for that comment.

  • For those of you know,

  • Debbie is a one of our teacher ambassadors.

  • We have a thousand teachers around the world

  • who are super users of Khan Academy

  • and our super teachers.

  • And they've been incredible mentors

  • for other teachers and other folks

  • to help them get started on Khan Academy

  • and thinking about how they can integrate

  • Khan Academy to their instructional practice

  • and especially in a time like this.

  • How they can integrate Khan Academy

  • into you know their virtualization plan so to speak.

  • So thank you Debbie for being an ambassador.

  • We really appreciate that.

  • You know a lot of what we do is informed by the teachers

  • on our Bachelor community.

  • Because we're trying we want to make sure

  • we have as much support for teachers as possible.

  • - So Sal our next question is fun from YouTube

  • by Prag Yamaha, her question is

  • hello how is it important to make notes

  • each time we watch a video?

  • - I think notes can be valuable.

  • I think the most important thing when you watch a video

  • is to try to do it in an active way.

  • So if the video is about to go through a worked example,

  • pause the video, try to solve it

  • at least attempt it yourself.

  • If the video is about to explain

  • the stages of mitosis for example if in your biology,

  • try to think about it yourself.

  • Say okay do what do I know about it,

  • what do I don't know about it.

  • So you get your brain primed.

  • Then on top of that I think it is useful

  • for a lot of folks to take notes.

  • It helps kind of multiple modalities to do that.

  • You know but for other people

  • it might be more useful to just really make sure

  • they're focused on what's being said.

  • I think sometimes notes can kind of be

  • kind of a blind process too.

  • So the more that you can take notes

  • but when you take the notes,

  • you're really processing.

  • So you're not just writing verbatim

  • or drawing verbatim.

  • You're looking at what's happening

  • and this is true whether it's a video or a classroom.

  • You're like okay now let me process that

  • and digest it in my own words,

  • I think that could be a lot more valuable.

  • The important thing is to really pay attention

  • and the beauty of videos is you can pause it

  • and say okay do I really get that,

  • how would I do it etc.

  • And then you can you can play

  • and see how the the Video Creator

  • has approached the concept.

  • - So on Facebook so we have RIA Bhatia

  • who's asking will Khan Academy be putting up

  • AP Computer Science a courses.

  • - The AP Computer Science, so we we have AP CS principles

  • that we already have it's you're probably aware of it.

  • We don't have AP Computer Science a yet

  • you know what I've told folks is

  • we're trying to add subjects as quickly as possible,

  • functionality as quickly as possible

  • but we are not for profit

  • that is philanthropically supported

  • and what a lot of folks

  • my wife was telling me last night

  • she's like Sal I don't think people realize

  • that Khan Academy is philanthropically supported,

  • Khan Academy is a large team

  • that that you know and even just our server cost.

  • So what I would say we want to be able to serve that

  • but we're gonna need a little bit more resources

  • and I'm not asking it from you Ria.

  • But I'm asking it from everyone listening.

  • The more support we have the more bandwidth we will have,

  • literally and figuratively

  • to be able to create more courses.

  • But I hope that over time we can fill out

  • more and more of these courses.

  • But AP CS principles is definitely a great place

  • to start if you haven't done so already

  • and also our programming platform

  • is a great way to learn.

  • It starts quite simple, it could be used

  • by an elementary school student

  • to kind of draw and make some animations,

  • but you can do some very sophisticated things

  • and things like object-oriented programming

  • and simulations you can go quite deep

  • on our computer programming platform as well.

  • - So Sal we have a question about AP exams

  • with the changes and how the exams gonna be

  • administered on YouTube of to cebra

  • asks should we study any differently

  • for the AP exams now that there are 45 minutes and online?

  • - What you know I I would still,

  • let's see the way I would approach it is

  • and on if if it's an AP exam that Khan Academy materials for

  • and we have chemistry, biology, physics, microeconomics,

  • macroeconomics, government and politics,

  • American history, CS principles

  • and obviously calculus and stats,

  • if it's one of those I would still try

  • to get mastery on Khan Academy,

  • you know a week or two before the AP exam

  • is as far as you can get.

  • And then a week or two before the exam,

  • I would look at old sample free response questions

  • and try to do as many of those as possible.

  • We have worked examples of many of those on Khan Academy

  • and many of those subjects

  • and so there I would give the same advice

  • that I've gave earlier as when the problem is presented,

  • pause it, try to solve it yourself

  • and then see how I or someone else

  • might have worked through that problem.

  • But I think if you do that

  • combination mastery on Khan Academy

  • and then you have a week or two

  • of really doing having a lot of experience

  • with the free response questions

  • and there's banks of those questions online.

  • Some of them and have solutions,

  • I think you're gonna be very well prepared

  • for I guess you know this new modality

  • that we might be seeing in a couple of in about a month.

  • - And so I would add to that,

  • um Adam on our content team and I

  • are working on how to put together a quick,

  • how to study for this,

  • based on the new information we have.

  • So that's a resource we're gonna try to get up

  • hopefully next week to the students.

  • - Yeah and I don't want to jump the gun

  • but you know I mentioned earlier

  • that you know we're exploring ways

  • to do academic webinars,

  • we just did one in algebra earlier

  • and so as we get closer to AP's

  • I hope that we we might be able

  • to explore some things there,

  • maybe do some office hours and things like that.

  • So let's see on Facebook Kristen Martinez,

  • their way to sign course challenges

  • to students as a teacher.

  • And I'll let the Khan Academy team

  • confirm what what I'm about to say

  • because I know some of the stuff is in flux.

  • You can assign obviously specific skills

  • on Khan Academy as a teacher

  • and parents can do this too.

  • You can essentially may become your students coach

  • by if they say add coach and enter your coach ID

  • and there's resources that explain how to do that.

  • But you can make assignments of specific skills

  • for specific videos, you can make assignments

  • on unit tests, you can make assignments for course mastery

  • so you could say hey I would like you to get 100% mastered

  • in biology by May 2nd, so you can do that

  • and I believe you can assign course,

  • it's definitely on our roadmap.

  • I don't know a Dan or someone from the team

  • can we confirm that we can

  • whether we can assign course challenges?

  • Well I'll wait for those those answers

  • once we once we can get confirmation.

  • But I do think course challenges are a great way

  • and I mean at minimum you could assign it

  • through something like an LMS

  • you know you can put a link to the course challenge.

  • But I do think they're a great place to start

  • especially if students already knows some of the material

  • and to understand where you are in the course

  • and they're also a great way you know

  • as the question about AP tests,

  • as you get closer and closer to the AP test,

  • I would take more and more course challenges as well.

  • 'Cause that makes sure that you are able to understand

  • what concept is applicable for a given item

  • without knowing what skill is from or what unit

  • and they're all mixed up.

  • So I would take course challenges

  • and I do a lot of free response for the AP students

  • to kind of prepare is it get closer.

  • - Yeah so Sal just an update on that one.

  • Currently you cannot assign course challenges

  • or spy review and course mastery unfortunately.

  • - Yeah you can't assign course mastery,

  • you can't assign spiral view

  • and yeah the spiral view

  • these distinct some mastery challenges

  • and those just show up

  • and then the course challenges

  • you could just send a link to your students

  • for them to get started on that.

  • But yeah unfortunately don't have that yet,

  • you know all of the other assignment

  • functionality that comes with it.

  • - Alright so we have a question from Facebook Chris.

  • Sorry um from Butarif Mohammed.

  • So how can I be a part of Khan Academy an educator?

  • - Well I think they you know we always have job postings out

  • so look at those but I think you know

  • in a general sense you know we are always

  • trying to connect with amazing educators.

  • So you should join our Facebook page,

  • our Facebook group for teachers called teach with Khan

  • and that you know obviously

  • stay involved in things like this,

  • I'm exploring other, we're exploring other projects

  • on how we might be able to leverage teacher volunteers

  • to help more students especially

  • in this time of school closures.

  • So we will be sure to keep people posted

  • on all of the above, alright.

  • So I could let's see ask another question here.

  • Someone said I added an hour to your daily schedule

  • for creative time where my kids have to create

  • rather than consume

  • their sewing doodling learning to juggle,

  • any other ideas for kids on what they can create?

  • So I that's a great idea that you added

  • that creative time you know in our V

  • and our first version of the schedules,

  • it was kind of implied

  • that could happen in the afternoons or the evening

  • but that's cool to kind of put it in the middle.

  • I do think for creative time

  • depending on what they're doing,

  • it is nice to have large blocks of time.

  • So 'cause you know you it just takes sometimes half an hour

  • just to get set up and then you might want

  • two, three hours to really create.

  • So encouraging people either do in the afternoon

  • or you can modify the schedule like that.

  • So beyond sewing doodling learning to juggle

  • I think there is there's a lot

  • you know drawing is great there's people on YouTube

  • who have these drawing tutorials,

  • you can ask them you know you can

  • storytelling is really incredible,

  • you can ask kids to come up

  • with a you know alternative reality of what's going on

  • or you know what would the world might look like

  • after through this crisis

  • or yeah there's just a lot of fun writing activities,

  • we've talked a little bit about coding

  • and this you know this is a great opportunity

  • for students to start exploring engineering things,

  • coding, making inventions.

  • I think social service can be creative.

  • You know what can especially kids do

  • for their community right now

  • I think this is actually a moment

  • where kids can step up to serve the elderly

  • especially with maybe helping them get groceries

  • or just giving them a source of connection

  • in this in this time of social distancing.

  • That can happen virtually or maybe just you know

  • waving to your your neighbor

  • or you know across the street and things like that.

  • So I think there's a lot of you know you can make videos,

  • you can make kind of Khan Academy style videos

  • explain things to your friends,

  • you can you know actually I played on the weekend

  • it was my family and another family,

  • we played this this this game called Pathfinder

  • it's kind of a new version of Dungeons and Dragons.

  • But that was it's very creative.

  • You go through these adventures together.

  • So I think there's all sorts of creative things

  • that you can obviously you know you can paint,

  • you can dance, you can choreograph,

  • there's there's a lot that can that can happen.

  • - So in closing just one more question from Facebook,

  • Josh Carroll asks, are there ways

  • to perhaps help parents teach math

  • in ways that show the applied side,

  • say show how to apply quadratic functions

  • to things like parabolic machine?

  • - Yeah I mean for that particular example,

  • if kids are curious you could actually

  • start going into the physics

  • which we have on Khan Academy

  • and if the students already know quadratics

  • and actually if they even know just

  • the basics of trigonometry which hopefully

  • they got from some of their geometry classes.

  • But you could even go over that with them.

  • They're ready to go into things like projectile motion,

  • two-dimensional projectile motion.

  • And you know one-dimensional projectile motion,

  • you actually don't need any trigonometry

  • you just need to know a little bit about quadratics

  • and so that's a very interesting application.

  • You can actually see how good your predictions hold up

  • or you can use the math to understand and go outside,

  • use a timer throw a ball in the air,

  • figure out how long it's in the air

  • and then based on that you can figure out

  • how high it went, which is kind of cool.

  • You can figure out how high a ball went

  • by timing it and then you could say

  • well how exact is it,

  • because in our equations we didn't have air resistance,

  • now we do and things like that.

  • But I think that's actually a lot of fun.

  • And then obviously you can do the same thing

  • with two dimensions.

  • You can figure out the angle by maybe where it lands

  • or how far it went based on measuring you know

  • there's all sorts of interesting things

  • you could do with that.

  • So physics is a great place to apply that type of thing.

  • You'll see a lot of that in economics as well,

  • and a lot of the basic algebra

  • actually you'll see in in chemistry as well

  • and actually some of the genetic stuff in biology.

  • So I think those are all really interesting.

  • They obviously exponential growth.

  • (laughing)

  • It's not hard to find videos

  • and we put a few on exponential growth

  • and how viruses spread

  • and how you can convert two days doubling

  • to what the factor is it's being multiplied

  • over any time period and exponential growth.

  • So I think you know if if there's a silver lining here,

  • everyone should get out of this crisis

  • learning about exponentiation.

  • And how to manipulate it and what its implications are.

  • So on that maybe not so uplifting note huh.

  • I just want to thank everyone thanks Dan

  • for helping me out, thanks for the entire team,

  • thanks for everyone who's joining,

  • we have some of these quick testimonials,

  • Schatzi Cunningham from Facebook

  • says my hope my homes loves Khan Academy,

  • we love you too.

  • We are actual home schoolers and we are subscribed

  • because you break things down clearly

  • so the youngest could even understand.

  • Well appreciate that Schatzi,

  • but you know we love feedback positive or negative,

  • we're always trying to get better.

  • And then you from YouTube,

  • we have Cory Geisler says thank you for all you do Sal

  • and I want to be clear it's much more than me,

  • Khan Academy is a team of over 200 people

  • and we have thousands of volunteers around the world.

  • You have helped me all year long,

  • it's not easy going back to college at 42 years old,

  • so thank you for all you do.

  • Well Cory we're about the same age

  • and yeah I could imagine you know

  • I have dreams every now that I'm going back to college

  • but I could understand.

  • (laughing)

  • But I'm a happy we kid we can support you

  • and I applaud you for going back

  • and always learning.

  • I think that's the biggest skill

  • of just continuous learning.

  • So you know thanks everyone in joining,

  • this is a great way to connect,

  • I feel more connected to you.

  • I hope we all feel more connected to each other.

  • All of humanity is going through this together

  • and I'm very confident we're going to get through this

  • and as we're going through this,

  • hopefully we build some empathy

  • and ways to connect with each other

  • that we can carry on once we get to some normalcy.

  • And I will remind everyone,

  • we are not-for-profit,

  • we are funded by a philanthropic donations.

  • I wanna thank some corporations

  • that have really stepped up recently

  • like Bank for America, 18 T Google org and Novartis now

  • to help support our response to the crisis,

  • our server costs are going to be 2/3 x

  • of what they normally will be

  • so with millions of dollars,

  • but we still need more help.

  • We're still running at a significant deficit.

  • It's not clear how long we can run like this.

  • So we need help we need donations from everyone,

  • even a two to three dollar donation

  • and these things add up

  • so that we can keep doing the Duke work we do,

  • we can keep the site performant,

  • we can keep serving folks

  • who might not be in the position to donate

  • and make sure we can support the billion of kids

  • around the world who are out of school

  • and the 50 million kids in the United States

  • who are out of school.

  • So thank you so much for joining

  • and I will see you tomorrow.

- Hello everyone, it looks like we are live
