Active teaching strategies for introducing radioanalytical techniques in analytical chemistry master degree. ⁴⁰K determination in Bananas

Radioanalytical techniques are singular spectroscopic techniques briefly or not at all presented in the analytical instrumentation courses. The use of active teaching techniques could contribute to amend this situation by motivating students to take these radiochemical courses where these active techniques are used. Therefore, the objective of this article is to present two strategies for radioanalytical techniques teaching. The first one, flipped classroom, introduces an article reading using a guide for teaching the radioanalytical techniques. The second strategy, case study, uses the determination of ⁴⁰K in bananas by its different emissions, for teaching the different aspects of the subject. (author)
