In this study we analysed what computational thinking skills pupils used when programming a small robot to solve a given problem, a simple programming task in which pupils had to select codes and put them in the correct place. Computational thinking is the process of (re)formulating a problem so that it becomes possible to use computer technology…

Moving among levels of abstraction is an important skill in mathematics and computer science, and students show similar difficulties when applying abstraction in each discipline. While computer science educators have examined ways to explicitly teach students how to consciously navigate levels of abstraction, these ideas have not been explored in…
