Toward the use of Generative AI to develop Computational Thinking by supporting Problem Decomposition

We present a possible applications of generative AI to support a Computational Thinking approach to learn programming principles with a particular focus on problem decomposition. Our approach is based on a visual tool that guides students in decomposing a problem in smaller task, prompting ChatGPT on demand via predefined queries designed via a preliminary prompt engineering experimental phase. The tool also provides the possibility of prompting ChatGPT to generate code in a bottom-up manner, reusing functions generated in previous steps. We illustrate here the main ideas with the help of a case-study.
