Khan Academy Programming Curriculum (for CSHS)

An overview of how we teach computer programming on Khan Academy, both via curriculum and community, plus how classrooms use it and our future plans.
Presented at CS4HS@Cal conference.

1. Khan Academy Programming
   ! compsci-feedback@khanacademy.org
2. What we teach Languages Uses Java Python C++ Haskell JavaScript Ruby Scheme Games Animation Hardware Robotics Data Science Simulation Mobile Websites Lua No Installation Needed Shareable Fun for Anyone Gateway Drug
3. ACE editor JSHint ! BabyHint ! Loop Checker ProcessingJS How students program
4. Curriculum
5. What we cover Drawing Variables Animation Text Functions Logic Looping Arrays Objects
6. How we teach: “Talk-throughs” Uses same environment they program in Making passive instruction interactive! https://www.khanacademy.org/cs/programming/drawing-basics/p/intro-to-drawing
7. How we improve talk-throughs Analytics
8. How we improve talk-throughs BEFORE AFTER
9. How we assess learning: challenges staticTest StructuredJS Esprima
10. How we improve challenges Challenges Attempted: 244,168 ! Challenges Completed: 162,858 ! Challenge Completion Rate: 67% Overall Analytics
11. How we improve challenges Manual Feedback
12. Giving more opportunity for practice: Projects
13. (Upcoming) Project peer evaluation
14. Advanced curriculum Natural Simulations Games & Visualizations
15. Translated curriculum Mostly translated in Spanish, partially in Portuguese/Hebrew (talk-throughs are subtitled, not dubbed)
16. Community & Cult(ure)
17. Questions & Answers
18. Votes and Spin-offs!
19. The Hot Programs
20. The Characters Hopper (...is a HER!) Winston Oh Noes Guy, the Error Buddy
21. ...The Avatars!
22. Classroom Use
23. Self-paced + Paired projects https://www.khanacademy.org/coach-res/reference-for-coaches/teaching-computing/a/pair-programming-in-the-classroom
24. Monitoring progress https://www.khanacademy.org/coach-res/reference-for-coaches/teaching-computing/a/tracking-progress-of-programming-students
25. Case Study: Lowell Additional projects: TRON, Pong, Hangman, Book https://www.khanacademy.org/teaching-computing/a/programming-case-study-lowell-high-school “Now, I spend much of my time thinking about how to bring out the power of us all coming together in the same room to learn to program.”
26. Case Study: Thailand “What’s in the News” ! “Technology Spot” ! CryptoCat for Chat ! Additional projects: Rock-Paper-Lizard-Spock Caesar Cipher Encryption ! https://www.khanacademy.org/teaching-computing/a/programming-case-study-going-beyond-the-ka-curriculum
27. Increasing Diversity
28. Completion per gender For the first challenge: ! Of the people who start it, 34% are female 66% are male ! 86.2% of males complete it (20762/23940) 86.7 of females complete it (10770/12494). http://cs-blog.khanacademy.org/2014/03/challenge-completion-across-gender-and_4.html
29. DonorsChoose program khanacademy.org/donors-choose Teachers get $100 codes for each female student, and $500 if 4 complete Experiment groups: $500 code for 4 completing, $500 cash for 4 completing, $0 for 4 completing 1544 teachers signed up ~2000 females completed ~2000 males completed
30. The Hard Parts
31. Reducing cheating SELECT user_key.name, stashed_code, backup_timestamp from [UserScratchpad]! WHERE stashed_code CONTAINS '"Shawshank Redemption”,'! ORDER BY backup_timestamp DESC; 1) Disable copy/paste 2) De-index solutions
32. Moderating the community
33. Future Plans
34. Algorithms 101
35. More languages HTML/CSS ? Blockly?
