Research Project Title
Optical spectroscopy: a vertical path for conceptual learning
Research Project Description
A need in Physics Education Research concerning optical spectroscopy emerges from literature: there is a lack of coherent didactical proposals and only few systematic studies on learning processes have been conducted.
In the theoretical framework of the Model of Educational Reconstruction, a specific research started analyzing the educational significance of optical spectroscopy. Its main focuses are the interpretation of the link between spectral lines and discrete energy levels, students’ interpretative models and strategies and the role of processes and apparatuses. The main research questions are: which are students’ reasonings concerning the interpretation of spectra? Which role do students assign to diffraction? How to build a Teaching/Learning vertical path in terms of energy?
Intervention modules with secondary school students and university biotechnology students are developed through Design-Based Research. Data from tutorials, interviews and problem solving activities are analyzed using qualitative and quantitative methods. Results allow to gain competence on learning processes and offer guidelines for developing a vertical path proposal for overcoming the main conceptual knots through Inquiry-Based Learning environments integrated with ICT and experimental work. In parallel, a research-based prospective primary teacher education intervention module is carried out to point out the main open problems.
