Hoe kunnen we je helpen?

Hi everyone!

I've just released a new course in our computing section: AP®︎ Computer Science Principles.

This review course includes 600+ practice questions, plus instructional articles and videos covering the topics of computers, the Internet, programming, algorithms, and data analysis.

Here are the highlights:

Mastery: You can repeat each exercise multiple times with new questions until you've mastered a concept, plus demonstrate your mastery with quizzes and unit tests.
Interactivity: Our instructional articles include interactive widgets for various concepts, like symmetric ciphers, public key encryption, and the traveling salesman problem.
Pseudocode practice: All the questions in the programming unit are written in AP CSP pseudocode, so that students preparing for the AP exam can practice transferring the programming skills they've learned into the pseudocode used by the exam.
Standards aligned: All articles and exercises are tagged with their relevant AP standards. You can search by AP standard in the Khan Academy search bar, and teachers can see the standards from the content assignment dashboard.
Teacher tools: Teachers can assign exercises, articles, or videos and track student completion. They can also preview all the questions in an exercise and drill down into a student’s report to see which questions they struggled with.

This course covers many topics that are new on Khan Academy, like internet protocols, cybersecurity, logic circuits, computer components, and file compression.

I will be adding an additional unit over the summer (on the Global impact of computing) plus iterating based on feedback from teachers and learners (like you!).

There's a lot to explore, whether or not you're in an AP CSP classroom. Hopefully you enjoy exploring the topics as much as I did!

The iOS and Android apps have generally not had the Computer Science courses, but this one is there in both apps.

@Regina Great question! I just checked, and the mobile app *does* show AP CSP. Some of the functionality doesn't work as well as it does on the desktop (namely, the embedded programs in the Programming unit), but it is all there!

Thank you so much for taking the time to create everything for this AP CSP Khan Academy Class. I had my students use it to review before the AP CSP Exam this year.

I would like to use the class for a summer assignment for next falls class. Do you have the approximate time it takes to complete each unit in the course? Any estimate would help. I'm not sure how many units I should have them do this summer. Thanks again, Steve

Hi Steve! By completing each unit, do you mean how long it would take for them to read the articles and do the exercises / master the unit? How much time will students have to spend? I think if I were to assign units over the summer, I'd assign Computers and maybe Internet (if enough time), given that CSP classes often spend lots of time on Programming (and that it's such a fun thing to learn in a classroom).

I'm also working on the Global Impact unit that will cover a range of interesting topics, but that won't be fully out until the end of June.

Pamela, yes on approximate time required to read the articles and doing the exercises. I want to use Khan for summer work, but I don't want them to spend too much time on the lessons. ( They need to enjoy their summers. :) )

I like your idea of assigning computers and maybe internet.

Thank you for spending the time on answering my questions and create these lessons! Steve

@Steve

Okay, I've put together back-of-the-napkin estimates in this spreadsheet:

https://docs.google.com/spreadsheets/d/1Wth9xMo5HIlVXnRwSXI4mONvm6sEUL-djSRiypj88X8/edit#gid=358108172

There are estimated unit totals in the first sheet and more details in other sheets. It's all very approximate, since there are a lot of factors at play (how much new material can a student learn before they need a break? how new are they to the topic? if they struggle and have no teacher/peers, how much does that increase the time it takes to get through a topic?).

Hopefully that helps you decide what to assign. Perhaps you can ask students to report approximately how long it took them. It'd also be interesting to have them reflect on what was the most new/interesting in the unit, and what they still have questions on.

I will have them try to log how long it takes them to complete the units I assign. Thank you so much for the spreadsheets with estimated times. This will most definitely help. Have a great summer. Steve
