Its pretty easy to criticise, so instead I will discuss the steps I would take to a student CS principles from my own experiences. I find graphs to be fundamental, so I would start the student out with them. 1. Teach the student basic concepts in graph theory such as nodes, edges, walks, paths, cycles, and structures such as trees, and linked lists. 2. Introduce the student to syntax trees as a means of representing mathematical equations, and the representation of them used in Lisp: (+ (* a x x) (* b x) c). 3. Describe dataflow graphs to the student. For example, loops are cycles in the dataflow graph, and infinite loops occur when the cycle is endless.
