Identifying student and teacher difficulties in interpreting atomic spectra using a quantum model of emission and absorption of radiation

Our study sets out to identify the difficulties that high school students, teachers, and university students encounter when trying to explain atomic spectra. To do so, we identify the key concepts that any quantum model for the emission and absorption of electromagnetic radiation must include to account for the gas spectra and we then design two questionnaires, one for teachers and the other for students. By analyzing the responses, we conclude that (i) teachers lack a quantum model for the emission and absorption of electromagnetic radiation capable of explaining the spectra, (ii) teachers and students share the same difficulties, and (iii) these difficulties concern the model of the atom, the model of radiation, and the model of the interaction between them.

The Development of Coaching Knowledge

Coaches are known to fulfill many different roles including leader, psychologist, friend, teacher, personnel manager, administrator, fundraiser and role model. The papers presented in this special issue emphasize these different roles by highlighting how coaches learn and how they foster an optimal learning environment. In the first section of this discussion article, I will briefly summarize the main issues covered in the five target papers. I will then propose that the learning environment of coaches needs to be put into a larger conceptual framework that would allow one to account for the variability of experiences that coaches go through before becoming a coach. The third section of this paper will describe three different settings in which coaches learn their skills. Finally, I will offer some concluding remarks and briefly outline directions for future studies.
