Educational Technology: Crash Course Computer Science #39

Today we’re going to go a little meta and talk about how computer science can support learning with educational technology. We here at Crash Course are big fans of interactive in-class learning and hands-on experiences, but we also believe in the additive power of educational technology inside and outside the classroom from the Internet itself and Massive Open Online Courses, or MOOCs to AI driven intelligent tutoring systems and virtual reality.

[@flyingllama87]

I'd like either: a) Math crash course b) Music theory crash course c) MORE COMPUTER SCIENCE!!!

[@Richard_is_cool]

Music theory. Please, please, please. Also history of music.

[@Marinealver]

For math look up MYWhyU and all their courses on Algebra. Math is such a broad subject we could break it into Crash Course Algebra and Crash Course Calculus.

[@sety409]

Thank you guys. Its hard to put in words how much online education has helped me. It's like leaving the cave in Plato's allegory. I never had access to quality education and have been surrounded by violence and drug abuse for a big part of my life. It gets lonely at times because many assume scholarity is education and don't see the value in interdisciplinary learning. Despite that, my life has improved because of people like you and I now KNOW that it's within my hands to develop myself and enjoy every minute of life I have left. From the bottom of my cerebral concoction of neurotransmitters 😉 THANK YOU

[@rogeliobuy3741]

One of my favorite series from CrashCourse. Kudos for making it to 40 episodes guys, see you next week.

[@RajRoy-qn1uk]

Nice

[@morezco]

please have Carrie Anne present a continuation of this series!

[@grumblering555]

As a teacher who often wonders about these developments (and how I could integrate them into my teaching), I want to thank you for summarising the current research so elegantly!

[@thomasgabby6214]

Series finale next week? aww felt that this series had the potential to go on longer than the other series. oh well, been a good journey; hope the last episode goes out with a bang.

[@Alverant]

I do computer programming as a career and I think the series is about long enough. To go further it would have to get into more detail on a subject which goes against the idea behind CC (give an overall summary on a topic) which won't be as interesting to most people. Maybe they could add one or two more classes (like object-oriented programming), but then it would start to lose focus.

[@klumbdolt4636]

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

[@MakDemonik]

Noooo! I neeed MORE layers of abstraction!

[@akai_suika]

Rewatching this during this kind of world event adds a little flavor to the context.

[@michaelcain9324]

I never thought I’d enjoy computer stuff, but watching your series has made me excited to learn more. With this series, I watched each video twice. Some more than twice, if I wasn’t getting it. So far I’ve loved it. Will try some free code camp and code academy to learn some languages, watch that free Harvard intro to CS lecture series here on KZbin (it’s not opening up again to take on edX until next year) and then I think code academy’s Computer Science path. And then maybe full stack development through them or the Odin Project. It’s exciting.

[@BrandonAiton]

I don't want this series to ever end! Please come back with a season 2 lol

[@neildeora902]

this is the start of my journy to online education

[@j0a0m4]

Can't believe this course is ending! Amazing work so far, I loved it.

[@edibleapeman2]

Now I want a Crash Course Teaching.

[@ProfessorSyndicateFranklai]

I doubt one singular thing will revolutionize education, but things do change. A lot of teachers show their kids videos, slide show presentations, and websites instead of lecturing and writing on the board. I think education will change, but not in a heart-beat.

[@jasminebishop]

Big fan of Crash Course, especially the Computer Science series. I have been waiting for an Educational Technology video - thank you!

[@mohdshamsulhaq503]

carrie i have learned a lot from you... just love and thanx. For the wonderfull job you have done.. thank you thank you thanks a lot and lot. i have watched all videos of yours from abacus till robot... learned every bit from scratch. No doubt is in my mind . You have cleared all my doubt.. .thanx once again. Gain Knowledge . Be happy. God Bless You.

[@frencheneesz]

The Diamond Age is a fantastic book. Good mention!

[@JFMeakerII]

Wonderful series everyone, it was a lot of fun and I learned a ton.

[@kittfedoroff4495]

Series Finale??? NOOOOOOOOOOOOOOOOoooooooooooooooooooooooooooo!!! Thanks Ms Philbin for your informative, fun course. Cheerio!

[@z0m0]

I just found this course and caught up only for it to end in a few days. Thanks for the information though, it has been fun learning it all.

[@simonkraemer3725]

Next week the final episode? Time for a Math Crash Course! Please!

[@timetravellingturtle]

This will definetly help with my Computer Applications Project.

[@gardenhead92]

I think the SAT writing tidbit speaks more to the quality of the human graders than to the algorithms ;)

[@L4PointLinguist]

True. Also I suspect when we're talking about "just as accurately" we're talking about on a macro scale, not an individual scale. No algorithm truly understands English, so with machine grading we're seeing correlations, like maybe for example quality academic writing tends to have more clauses per sentence than poor writing. A program that doesn't even understand the writing, that just counts the number of clauses per sentence, is not going to grade correctly at all, but it happens to correlate with an accurate score about as often as a tired, biased, or poorly trained human does. Of course, the clause-counting app can go through tens of thousands of essays a minute and doesn't expect to be paid a salary, so testing institutions are strongly incentivized to go with their app. As long as your essay isn't one of them it makes an error on, there's nothing wrong with the testing institution following its incentives... ...until people start figuring out the algorithm and we get generations of students being trained to write to impress a computer that doesn't understand English instead of just doing quality writing in the first place.

[@barryfraser831]

we already do the last bit in school teachers know what the testers want and teach you how to do it in that way it would be no different with computers

[@L4PointLinguist]

The difference is that teachers teaching to what human raters want are still pushing students to use language to communicate with another human being. The "5-paragraph essay to appeal to a human SAT rater" might be a very limited genre of writing, but it is actually a form of writing. If teachers were to push students to write in a way that games an essay-rating algorithm that isn't part of a fully-sentient, language-capable strong AI, then communication wouldn't actually be happening. Arguably, language might not even be happening.

[@AmaroqStarwind]

When I was in high-school, I once wrote a paper about a new way to educate students by turning a curriculum into a sort of Roleplaying/Puzzle/Exploration game in terms of non-linear progression and teaching mechanics, only a bit more abstract. It was heavily inspired by my favorite MMO at the time, EVE Online. Unfortunately, I lost that paper a long time ago. You should look up the channel _Extra Credits,_ as well as the show _Digressing and Sidequesting_ (which is under the umbrella of The Game Theorists). The former is a channel dealing primarily with the principles of Game Design, but has an episode regarding "Gamifying Education" / "Gamification of Education". The latter, meanwhile, has an episode about Super Metroid, and how it is a shining example of how a well-designed game can effectively teach players through their design, and without using any words.

[@rcookie5128]

Good job CrashCourse team! :) had a blast watching this series and I'm excited for the final episode next week..

[@TheLanCave]

This was a particularly interesting video for me, as I'm learning html coding via online courses. I think Carrie Anne believes in me.

[@Kisuke323]

Thank you for advice! I've been looking for these two week and now, while procrastinating, I finally found them :)

[@NoahNobody]

Stackoverflow is a great example of a giant searchable FAQ for all of programming.

[@UFBMusic]

The Diamond Age is one of my favourite books!

[@Alverant]

It's been a great series! Let's hope for one more level of abstraction!

[@danhiebert0001]

Never been so saddened by the end of a series finale. Don't do it!!!!! Plzz

[@candraadiputra]

Best crash Course so far!, i Hope there will be Computer Science 2 with fokus on *Deep Technical Content* about Operating system, Programming language, database, AI, Cloud computing, AR and VR .

[@michaelmcginn3731]

See... google. this course give you a great foundation to formulate your search queries so you can deep dive into the subject matter your most interested in.

[@not_a_human_being]

Thank you for creating an amazing course! :)

[@EnginAtik]

This is a very well thought/made episode. Kudos!

[@Urbanfour]

You know what would be a good follow up series. CC Coding (programming), CC Networking, or CC Engineering

[@brianomahonyy]

If anybody is interested in a network-based (as opposed to broadcast) variant of the mooc they should check out the history of cMOOCs. cMOOCs or connectivist MOOC were actually the original model formulated by canadian educators and technologists like stephan downes and george siemens. It's based on quite a radical and emancipatory pedagogy and, for me, much more interesting than the later, broadcast model formulated by the ivy league/venture capital crowd

[@davidchidester5463]

I dealt with this type of tech in an accounting class. Wasn't very well developed. You had to put exact answers even if there was more than one way of entering your answer. These methods work well with scientific studies like algebra, but are total trash with fill in the blank type questions or essay answers.

[@gusutabopb]

"Series finale next week" :(

[@old-moose]

We shouldn't let our vision for the use of edtech be limited by the band wagon effect. I would like to see TOOCs (Tiny Open Online Coures) developed to help students in courses that are application or creative in focus so they can get personalized support from the teacher.

[@GuidoPerdomo]

I loved how Carrie said "Despacito"!!

[@annshevchenko7962]

She is sooo cuuute ))) Interstring and useful videos ))) THANKS A LOT

[@AnotherGradus]

_The Diamond Age: Or, A Young Lady's Illustrated Primer_ by Neal Stephenson is an excellent book. If you've watched all parts of this series, you should definitely read it!

[@brocksprogramming]

Way to go Carrie Anne!

[@jakebyday]

Please do something on quantum computing for your series finale!

[@subhroprivatesen4623]

Carrie Anne ma'am.. Your videos are remarkable..amazingly amazing ..the concept I gained from some videos really helped me to understand the basic fundamentals of a CPU. I had a request to you ma'am. If you could make a video about IBM's AP 101 and how it works ..and how it guided the space shuttles for reentry maneuvering TAEM .. If you please could make a video about it I will be grateful. I've searched our local library and the city library and also all over the internet.. Google ,KZbin and all but couldn't find a suitable concept or working procedure. I'm asking a lot I know. But ma'am I'm kinda counting on you. Place I'm from people don't usually feel interested in these. Thank you. I'll be grateful.

[@timothymclean]

You can get a head start on next week's topic by hitting some good futurist educational channels. Does anyone have some suggestions?

[@timothymclean]

I'll start with my suggestion of Isaac Arthur.

[@Viperzka]

Kurzgesagt

[@foxsmith770]

"Uploaded with new skills, directly into their brains." Isn't that like "The Matrix"?

[@Gold161803]

Fox Smith ..............I know kung fu.

[@michaelmcginn3731]

Exactly. See my previous comment on that

[@allertonoff4]

we believe .. likewise .. Bang ON there with you guy's .. developmental 'Conceptual Models' .. is where it's at ! A4

[@cadmium-ores]

*busts down the door* UPLOADING OUR BRAINS????? GET HYPED for both the episode and that actually happening

[@PetersonSilva]

Isn't duolingo an AI driven tutoring system like the one explored in the video? It felt like it merited mentioning :)

[@dlseller]

I hate that feeling when you suddenly realize you're at the end of a good series.

[@ChristopherHarris]

Great video! Thanks!

[@Karyotyping]

First thing that popped into my mind about next week's topic: That sounds like Neuromods from the game Prey!

[@donnminor9768]

There should be an episode about the blockchain

[@aloe.lavendar]

This is so relavent now!

[@armorsmith43]

I wish youtube had a setting where videos play at 90% speed.

[@armanke13]

Yea agree.. but if you on desktop there are chrome extensions youtube playback speed control and youtube speed changer for more speed option.

[@Richard_is_cool]

Does anyone know of any education software like the one described in this video, that would be online and free?

[@wifiindi232]

What app to creat animation and video like this...?

[@libummendaciumest3328]

Quick and dirty IQ test: average the speeds that you can watch CC and still understand. Example I could understand CC CS at 1.5 and 2(with cc). But CC Physics has me watching at 1. If I round my average speed to the closest speed on the youtube player, and multiply by 100: I have an IQ of 125. Look mum! I'm smart!

[@rdvankayahan9753]

Teşekkürler

[@happyfakeboulder644]

Seriously, no one in the comments brought up CGP Grey's "Digital Aristotle"?

[@armanke13]

Happy Fakeboulder. Thx for mention it, haven't know about it before.

[@TheMaplestrip]

Series finale!? :o :'(

[@tuhinshaikh96]

Its not other types vedio on cc which are compact

[@joseponce6250]

Really nice videos, great teacher!!!!!!!!!!!!!!!!!!!

[@theshyguitarist4536]

Series finale next week?! 😭

[@Grimlock1979]

Toilet paper should hang over. Just saying.

[@OldManFire]

the fact that cats disagree just proves even more that they are assholes

[@BTheBlindRef]

I know. I was waiting for her to circle that one and say "that way... that's the right way". I'm not even sure how it's a debate. It's superior in every single way!

[@sunbro9076]

That Raspberry Pi shirt though.

[@MakeMeThinkAgain]

Here's a problem for machine learning (or our AI overlords), If educational technology keeps getting better and better why is it that the average person doesn't seem to be any smarter?

[@KaletheQuick]

Amazing shirt

[@narutokunn]

No dont go

[@narutokunn]

Please dont go

[@bobfearnley5724]

Aww, this series is ending soon :(

[@ransom4734]

Can super computer of IBM get Hacked and start learning itself

[@Akashascosset]

They made it to 32 episodes, so I expected the finale to be either episode 63 or 127

[@danielmclaughlin5573]

Series finale?! NO!!!

[@londonnight937]

And yet, the majority of the world's education systems are stuck in the 1910's era, sometimes worse. This goes to show that its not enough to invent technology that brings the potential solution to a problem, you also have to implement the solution. I'm not sure why change is so slow, but this problem (education) is certainly slowing humanity's evolution overall.

[@saltyc3453]

Notifsquad

[@saltyc3453]

Edit-firsteh

[@ryandupuis5860]

same

[@angeldude101]

Only one episode on brain uploading? :( I can't wait for the real science behind Arik from the C1764 series on /r/hfy. Oh, and I guess it's the finale too.

[@stephans1990]

I love how I'm learning about taking your time to study subjects while I'm playing these video's at twice the normal speed XD

[@amedicabg]

The idea of uploading anything into our brain is quite a scary thought Ghost in the Shell anybody?

[@braalexghofficial8012]

CYBERSECURITY CRASH COURSE WILL BE APPRECIATED

[@DanThePropMan]

And yet somehow we got MyMathLab.

[@megakidicarus4647]

There is an explanation for it we just don't have all the details of the inner works of Pearson, until someone leaks this information I doubt we will.

[@davidchidester5463]

For real. Pearson is such a ridiculous company. New editions of all their texts almost every year. And very little learning actually happening because lots of teachers take a hands off approach because they assume MyLab will do their jobs for them.

[@yanaafanasyeva8894]

What's wrong with it?

[@oldcowbb]

this episode is supported by skillshare

[@12co3dy21]

Not complaining but why were most the pics that you showed, included Indian/ south Asian women?

[@victorcaicedo781]

I'd like learn programming language

[@nofacee94]

which language?

[@FalbertForester]

This series is a good start towards doing that. There are a number of good "how to learn programming" resources out there, and you can pick from a variety of computer languages to learn. In short, though, computer programming is: 1) recognizing the problem 2) breaking the solution to the problem down into small, simple steps 3) writing the code and combining the small steps 4) test, test, test, test, test, fixing the mistakes between each test.

[@NoahNobody]

PHP (7.2) or JavaScript

[@Grimlock1979]

PHP and Javascript are the top 2 horrible languages.

[@gosnooky]

Java. Just saying.

[@elektrikhd]

The video speed controls? Haha, nice try! Would be nice if they added something like...oh, that wasn't a joke.

[@ajaxkhan102]

Please do actual computer science video like the registry and RAM, CPU stuff..... That was way cooler than these history packed videos. I know this is crash course and it is going to end like this but hey those episodes were awesome.... Like if u agree

[@Viperzka]

Those topics were at the beginning of the course.

[@ajaxkhan102]

Don Reynolds yep I agree but somehow they were actual computer science.... They should be extended...

[@tomstieve]

Gangnam Style? Carrie Anne, we have to update your cultural references!

[@LLL124Original]

I order books easier than ever!

[@VideoBoxAhtishamdrosh]

What is Network

[@robbedemey]

Learning with videos at x0.75 speed? I'm learning at x2.5 (you will addapt very quickly to watching videos at high speeds), I can watch more then twice as much footage while the videos keep me engaged, because there is not time to drift away...

[@robbedemey]

Ofcourse, when I there is something I dont understand, or if I have to take note, I watch at slower speeds. But being able to rapidly go trough the non-information parts of every video is very handy.

[@johndoh1000]

ayyyy already watching at 2x speed

[@etothepii8885]

"So imagine our student is working on this algebra problem: 3x + 7 = 4. The correct next step to solve it is to subtract both sides by 7." This brings up a problem of educational software: subtracting by 7 is *not* the only next step. If a student approaches the problem differently, they could divide by 3, and that would be *just as valid* (not as efficient, but this is just a simple example.). If educational software is *too* pushy in its methods and doesn't allow enough freedom on the user's part, then it can actually be more of a hindrance to learning than a boon. My younger siblings have struggled with annoyingly specific and unclear software, so this issue goes hand-in-hand with the psychology of computing, and the considerations of usability. (Comment 129: breaking the computational symmetry of 2^7!)

[@darthteej1]

The only complaint I have with this entire series is that the tips in this EdTech episode for writing notes and following examples yourself would have been really useful earlier on!

[@w.e.4277]

Shhtudent?

[@qualquerum3158]

Portuguese subtitles

[@willoo2873]

Can I have Hank Green?

[@avi12]

2:31 Who else did it as the cursor clicked the 0.75 option?

[@dlseller]

Wasn't the first time Edison was wrong...or the last. Just ask Tesla.

[@cosmoruski2012]

Manfred Spitzer disagrees

[@wolfyeb]

I need John Green to replace OK Google. Someone get on this.

[@michaelmcginn3731]

Add celebrity voice packs to all these virtual voice assistants. Like your gps in the car.

[@tomscisci7331]

John Green, *where I can find crash course world history?* *"On youtube, Crash course or CC world history, is an one course of crash course channel. You will find on official crashceourse channel."*

[@susanthawarnapura]

aren't we discuss neural networks,machine learning...

[@Gold161803]

susantha warnapura 3blue1brown has a fantastic three-part series about neural networks

[@Viperzka]

It was covered four or five episodes ago.
