Evaluación del proceso enseñanza-aprendizaje de enlace químico mediado por un software de laboratorio en una institución educativa del municipio de la Paz-Cesar-Colombia

Abstract

The health emergency generated by the presence of the COVID 19, the lack of experimentation due to poor maintenance of chemistry laboratories in public schools, the low motivation shown by students in learning chemistry and the need for lifelong learning, take us to the need to innovate teaching practice. It is because of this, that the research objective was to evaluate the teaching-learning process of the chemical bond concept, using the Model Chemlab 2.5 laboratory simulator in tenth grade students at the Ciro Pupo Martínez school in the town La Paz, Cesar. The type of research is correlational and evaluative, with an exploratory and quasi-experimental quantitative approach since the sample was intentional. Two groups were formed, one control and another one experimental, two questionnaires were used for data collection: a knowledge test and a Likert-type questionnaire. As a result, it was established that there are statistically significant differences between the averages of the results of the knowledge and motivations test, against the approach to the chemical bond issue with the Mann-Whitney-Wilcoxon test, that is to say the alternative hypothesis was accepted. It is concluded that planning the pedagogical practice through a didactic sequence mediated by a Model Chemlab 2.5 laboratory simulator, substantially improves the teaching-learning process of a chemical bond, because it allows presenting the contents in an orderly, sequential manner prioritizing the activities and generating meaningful learning with the combination of cognitive, motivational, and attitudinal factors.
