I believe that instilling the right frame of thinking is the sole purpose of teaching. This is the underlying tenet of the course Computational Thinking that I teach to the first year Freshmore students at Plaksha University. The course is designed around a set of broad frameworks underlying program design. The students are taught to think about program design through problems by illustrating how the design emerges from these frameworks. This is key to computational thinking. By learning to make the connections between problems and structures, students become better positioned to imagine the connections between newer problems and their underlying program structure.
Another feature that we introduced in this course is the element of posing a computational problem. This is a subtle aspect of computational thinking that is seldom touched upon. In the Computational Thinking course, we introduced a joint assignment with the Center for Thinking Language & Communication (CTLC) team. In this assignment, the students were asked to pick a theme and then identify a computational problem within the theme. An example of a theme is congestion, and a computational problem is traffic light management at an intersection. While traffic light management is not a trivial problem by itself, the students were required to pick a structure from the structures they had been introduced to. The idea of this exercise was to enable them to see the intricate connection between a construct or structure and the scope of the problem it could solve. It was to enable the students to appreciate where new computational constructs possibly arise from, the boundaries of what older constructs can solve, and what they cannot solve. It was in a way an exercise to appreciate the limits of what was taught in the class and what lies beyond, which I believe is true knowledge.
