Objective. Evaluate the General Physics courses (theory and laboratory) of the Science Teaching career with the university teaching staff, in the period from 2014 to 2019, to identify the strengths and weaknesses in the methodology and propose new educational strategies. Method. The research was conducted through a virtual survey with the LimeSurvey software to the teachers who have taught Physics courses for the Science Teaching career in the last five years; the survey was applied to the total population of 20 teachers, but only 12 of them answered it. The instrument was designed by the teaching staff working on the project to improve the laboratory manuals. The instrument analysis was carried out with the help of an Excel spreadsheet provided by the LimeSurvey software. The instrument was validated by IDESPO staff of the National University regarding the relevance of the content of the statements, the clarity of the questions, and the coherence with the objective of this study. Results. The structure and organization of the General Physics courses have a positive assessment by the teachers, who also showed a preference for the traditional lecturing; but even so, they are willing to train and learn new teaching strategies. Conclusions. The results of this investigation show that teachers are open to technological change and to working on the challenges that government policies have proposed.
El objetivo de esta investigación es explorar si existe una relación entre las ondas magnéticas de Rossby rápidas o lentas y ciertas observaciones de la actividad solar de largo y muy largo plazo (meses, años, décadas…). El artículo intenta mostrar si los periodos de esas ondas y sus características corresponden a los valores de duración los ciclos de Rieger, Haly, o bien cuasiperiodos de llamaradas y eyecciones de masa coronal. Se inicia con una revisión bibliográfica y un resumen de los resultados de una tesis doctoral que resuelve completamente el modelo matemático en cuestión, con las ecuaciones derivadas de ese trabajo previo, se calcula los periodos de las ondas que serán comparados con las observaciones. Estos resultados teóricos sugieren que cierta actividad solar podría deberse a las ondas magnéticas de Rossby, originadas en el interior del Sol, específicamente en la tacoclina. Las ondas lentas se proponen ligadas a las periodicidades de largo y muy largo plazo y las ondas rápidas de Rossby se asocian con periodicidades de unos años a meses. El estudio de estas perturbaciones de Rossby y sus propiedades, sin duda, va a ayudar a comprender el origen y las características del campo magnético del Sol.
