Python is the most popular intro language: But what about CS Principles?

Philip Guo did an analysis of what top CS departments teach in their introductory courses (see link below) and found that Python now tops Java.  MATLAB tops C and C++ (though not if these are combined), and Scheme and Scratch are near the bottom.

Philip’s analysis did include CS0 and CS1 courses, which points to a problem for adoption of CS Principles as an Advanced Placement exam.  Scratch is the only one of the popular CS Principles languages now used in the CSP Pilots that is also being used in CS departments.  Other CSP popular languages include App Inventor, Alice, Processing, JavaScript, and Snap!.  Those don’t appear in Philip’s results to any significant degree.

It’s reasonable to say that an AP will only succeed (e.g., students will take it) if they can get credit or placement for the exam in college or university.  Typically, colleges and universities give credit for courses that are currently taught.  Will we see colleges and universities start teaching CS Principles?  Will they give credit for a course that they don’t teach? For languages they don’t teach?  Maybe we’ll see more of an influx of CSP languages and courses into colleges and universities. I predict that we won’t.

Scratch is the only visual, blocks-based language that made this list. It’s one of the most popular languages of this genre, which include related projects such as Alice, App Inventor, Etoys, Kodu, StarLogo, and TouchDevelop. The creators of these sorts of languages focus mostly on K-12 education, which might explain why they haven’t gotten as much adoption at the university level.
