TITLE: Let's Not Forget: CS 1 Is Hard For Most Students AUTHOR: Eugene Wallingford DATE: December 27, 2014 8:47 AM DESC: ----- BODY:

... software is hard. It's harder than
anything else I've ever had to do.
-- Donald Knuth

As students were leaving my final CS 1 lab session of the semester, I overheard two talking about their future plans. One student mentioned that he was changing his major to actuarial science. I thought, wow, that's a tough major. How is a student who is struggling with basic programming going to succeed there? When I checked on his grades, though, I found that he was doing fine in my course, about average. I also remembered that he had enjoyed best the programming exercises that computed terms of infinite arithmetic series and other crazy mathematical values that his classmates often found impenetrable. Maybe actuarial science, even with some hard math, will be a good fit for him. It really shouldn't surprise us that some students try computer science and decide to major in something else, even something that looks hard to most people. Teaching CS 1 again this semester after a long break reminded me just how much we expect from the students in our introductory course: In a single course, we expect students to perform tasks in all three of these modes, while mastering a heavy load of details. We expect them to learn by deduction, induction, and abduction, covering many abstract ideas and many concrete details. Many disciplines have challenging first courses, but CS 1 requires an unusual breadth of intellectual tools. Yes, we can improve our students' experience with careful pedagogy. Over the last few decades we've seen many strong efforts. And yes, we can help students through the process with structural support, emotional support, and empathy. In the end, though, we must keep this in mind: CS 1 is going to be a challenge for most students. For many, the rewards will be worth the struggle, but that doesn't mean it won't take work, patience, and persistence along the way -- by both the students and the teachers. -----
