Which cognitive action involves giving a practical exhibition as an explanation?

The cognitive action that involves giving a practical exhibition as an explanation is to demonstrate. This term signifies the act of showing how something works or explaining a concept through practical examples or activities. By demonstrating, one is able to effectively convey understanding through observable actions, thereby facilitating learning in a tangible way.

For instance, in a science class, a teacher might demonstrate a chemical reaction by mixing substances in front of the students, allowing them to observe the process and understand it better. This hands-on approach to learning is central to the concept of demonstration, as it combines theory with practice.

In the context of the other choices, determining refers to identifying or concluding something based on information or evidence. Devising involves creating or planning something, often focusing on formulating strategies or methods. Deriving focuses on obtaining or gaining something from a source, often through logical reasoning or calculation. While these actions may contribute to understanding, they do not encompass the practical exhibition aspect inherent in demonstrating.
