El electrón ha de perder energía a medida que irradia radiación. Esto hará que orbite cada vez más cerca del núcleo, a mayor velocidad y por tanto con mayor frecuencia. El espectro emitido debería contener todas las frecuencias, y no es esto lo que se observa.

The effectiveness of the problem based teaching on the science learning has been highlighted by the didactic
research. This teaching model is characterized by organizing the units around problems and by proposing a research plan to find a solution which requires concepts and models to b...

Computational reproducibility is the ability to obtain identical results from the same data with the same computer code. It is a building block for transparent and cumulative science because it enables the originator and other researchers, on other computers and later in time, to reproduce and thus understand how results came about, while avoiding...

... This analysis covers the problems, hypotheses, ideas, and experimental research that make it possible to identify the key aspects and the main difficulties that historically the scientific community had to overcome in order to establish the scientific models that we set as learning objectives [ [45][46][47][48], among others]. With regard to the students' difficulties on the subject, a review of previous research has been conducted [49,50]. Moreover, preliminary research was conducted on the students' difficulties in relation to the objectives defined in the TLS [19]. ...
Research has highlighted difficulties experienced by students when studying quantum physics in introductory courses. In this paper, we present a teaching and learning sequence (TLS) aiming at introducing a quantum model of emission and absorption of radiation and we assess its impact on the students’ learning about atomic spectra. The TLS has been designed based on the contributions from physics education research and it was implemented among high school seniors. A detailed description of the TLS is also presented accompanied by a description of how it is implemented. Based on a pre- and post-assessment questionnaire and student interviews, we conclude that students are able to successfully use the models to reason about relevant phenomena.
