Proposta de aplicação das tecnologias educacionais no desenvolvimento do tema: óxidos, propriedades físicas e químicas no ensino médio

Abstract

Worldwide, in a particular case in Mozambique, education is on the decline, with regard to respect to quality education. One of the questions most raised by society in general is how and where to find quality education. Having a well-educated society constitutes still a major concern and challenge for education today, as it involves many factors such as: material, human resources, means, among others, etc. The present work is part of one of the research areas of the Department of Chemistry, dedicated to the evaluation of teaching quality parameters. Throughout the study, we will focus mainly on the teaching means that can be used in class, starting with the assumption that their choice has a positive impact on the teaching-learning process. This work aims to propose the application of technologies activities in the development of the theme: oxide, physical and chemical properties in teaching (basic technical education) on the basis of appropriate teaching methods and means, such as preparation of lesson plans for teachers, adaptation of the ESG program for teaching medium and elaboration of didactic means (posters) and application of posters in the classroom. For confirmation of the efficiency of the proposal, two classes were chosen with a close pedagogical performance at the Commercial School of Maputo, that is, an experimental class (where the posters were used and the experiments were carried out) and another control group (where the poster was not used and the experiment was not carried out). For the accomplishment of this work, the following methods were used: qualitative, inductive and experimental method. Because methodologies used, the results obtained from the surveys and interviews with students and teachers, as well as those obtained in the experimental class, are satisfactory (with 42% of students with good pedagogical performance compared to the other class); show of it is clear that the use of educational technologies is of extreme importance in the PEA. Were qualitative, inductive and experimental methods were used as methodologies and the study, carried out in demonstrated that there is a possibility of using the proposed educational technologies, thus contributing to quality education
