The enzymatic determination of glucose in soft drinks, based on the glucose concentration measurement by means of the coupled reactions of glucose oxidase and peroxidase, has been implemented at the University of Malaga and optimized according to the Biochemistry and Chemistry undergraduate students' results and feedback throughout the last few…

This study concerns a framework for designing Teaching-Learning Sequences that aims to integrate the implementation of scientific practices in the context of daily problems. Said framework consists of three stages (formulation of the design principles, instructional design and design of the learning activities). It is based on four design…

This paper examines the process of high school students' planning investigations in the chemistry laboratory across two consecutive academic years in terms of their actions and their progress. The context is a set of five inquiry-based laboratory tasks in which participants (9th and 10th graders, 14-15 and 15-16 years of age) are required to plan…

This practical paper describes a novel fluorescence imaging experiment to study the three processes of photochemistry, fluorescence and thermal energy dissipation, which compete during the dissipation of excitation energy in photosynthesis. The technique represents a non-invasive tool for revealing and understanding the spatial heterogeneity in…
