Hi all, I'm Fernando Alegre. I am working on developing curriculum for high school computer science courses. The first course I developed, called Introduction to Computational Thinking, has been running as a pilot in several high schools in Baton Rouge, Louisiana, for two years. The course uses Chris's CodeWorld platform, so that schools do not need to install anything. The course covers relatively little content in terms of computer science, but it is heavier on the math than other introductory courses, including Bootstrap. In the summer, I have a five-week all-day professional development program, where I have the teachers do all the activities in the course, so that they go from zero-knowledge in programming to being somewhat comfortable with teaching the course and helping students debug their code. I am also testing material for other courses with a couple of teachers and also directly with a small group of advanced students. I liked the CodeWorld environment so much that I decided I would try it with the advanced students, and the feedback I got has been very interesting. Apart from their dislike of the syntax and similar nuances, their main complaint is that functional programs are too dense, and that increases their cognitive load too much, so that, even though they can write the code, they do not enjoy doing it. I am struggling to find ways to make it more enjoyable for them, as it is really fun for me. I someone is interested, I can provide more details about all that. Regards, Fernando
