Guía de experiencias prácticas para el aprendizaje teórico-práctico sobre compuestos de interés biológico en 3º de BGU, U.E. Roberto Rodas.

Abstract

Practical experiences are necessary to develop in individuals capabilities and skills oriented towards scientific thinking, as demanded by society. This has presented challenges at the Roberto Rodas Educational Unit, especially in Chemistry, due to the theoretical approach given to it, without considering it a science that requires experimental demonstrations. The objective of the research was to develop theoretical-practical learning of Chemistry to understand fundamental concepts about compounds of biological interest through a guide of practical experiences in the Third Year of the Unified General Baccalaureate of the Roberto Rodas Educational Unit. It was developed under a socio-critical paradigm and a mixed (qualitative-quantitative) and quasi-experimental approach, in which two groups were considered: one control and one experimental, in which the dependent variable was evaluated in a similar way, being experimental to which practical experiences were applied. Data is obtained based on techniques and instruments, such as survey, interview guide, pretest, posttest and observation guides. With the data obtained, the methodology used and the reasons why experiments were not carried out were diagnosed. The implementation of the proposal has contributed to an improvement in the academic performance of students. The use of the guide is pertinent, as it facilitates the development of experimental practices, being a more attractive and striking methodology for learning.
