Didactic strategies for natural sciences learning in pandemic contexts: teacher case study from Antofagasta

Abstract

The present study describes and analyzes which where the main didactic strategies used by science teachers for natural sciences learning with the use of TIC tools in the online class modality. The research is presented as a case study, not experimental, with a non-probabilistic purposive sample. The subjects correspond to teachers who teach naturas sciences. The data was collected through a closed item survey with a Likert scale, previously validated by expert judges, and analyzing the data under the SPS program. Regarding the open question a qualitative analysis of documentary review is carried out and the relationship of TIC skills for learning is analyzed. The results indicate a frequent use of observation strategies by digital means and use of a slide presenter for online classes. On the other hand, a low use of experimentation and scientific inquiry strategies due to the complexity of access to resources for its execution. Regarding the classification of teaching strategies used and their relationship with TIC skills for students, all of them can be covered through digital media. The return to presentiality poses challenges to adress the use of key teaching strategies for understanding the great ideas of the natural sciences. The strategies of experimentation and scientific inquiry in the return of presentiality will be key to strengthening the learning of natural sciences through practical activities.
