Aproximación a las dificultades para la ejecución de trabajos prácticos de laboratorio de biología en educación media

Abstract

The practical laboratory works are key in the teaching and learning process of biological sciences and, consequently, research on this subject constitutes one of the most important lines in science didactics for a long time, so the aims of the present work is to determine the viability for the development of practical activities of biology in secondary education. To do this, an online survey was conducted with 24 practicing teachers. Detecting various reasons that make it difficult to carry out these activities, among which aspects related to the demotivation of students, lack of resources and adequate spaces to carry out experimental work, as well as very short class periods stand out. This leads to the belief that, for many teachers, practical laboratory work has taken a back seat and is no longer inclsed as a fundamental activity within work schedules. In adition, the use of telematics teaching is discussed in times of a COVID-19 pandemic, which allows us to mitigate the lack of traditional TPL, through the design of new teaching strategies.
