Hi John,
The Computational Thinking skills that are taught in these Wolfram U courses are different from those normally found in a computer science curriculum.
Computational thinking is a process in which you creatively apply a four-step problem-solving cycle to ideas, challenges and opportunities you encounter to develop and test solutions. The emphasis is learning how to take real-life situations and abstract—often to programs—so a computer can calculate the answer.

These courses teach Computational Thinking using the Wolfram Language, and you will learn elements of Wolfram Language as part of them. However, Computational Thinking itself is a process that can be applied using any language/software.
