The issue of didactical suitability in mathematics educational videos: experience of analysis with prospective primary school teachers.

Abstract

The number of educational videos available on the internet on the most varied topics is rapidly increasing. These include mathematics videos that cover virtually any type of curriculum content. However, their quality as a learning resource varies greatly. As a result, it is necessary to provide teachers with tools to enable them to analyse the appropriateness of using educational videos, considering the various aspects involved. This paper describes the design, implementation and results of an educational intervention with 93 prospective primary school teachers, focussed on developing their ability to analyse the educational suitability of videos about proportionality. Preliminary analysis of the video revealed significant errors and inaccuracies in the definitions, propositions, and procedures, as well as shortcomings and inaccuracies in the arguments, and so its level of epistemic suitability is rated as medium. However, the majority of the prospective teachers rated its degree of suitability as high in almost all components. Students regard studying didactic suitability and implementing it through components and indicators as positive, believing that this activity facilitates professional reflection. However, mastering this tool requires analysing a greater number and variety of videos and further collective discussion of the results of the analyses performed by the students.
