Identificação e descrição das dificuldades na aprendizagem de cinética Química: o caso da 12ª classe do ensino secundário geral 2

Abstract

The present work has as main objective to identify the main difficulties in the learning of Chemical Kinetics by students attending the 12th Class of the National Education System at Josina Machel secondary school. For this purpose a series of interviews was carried out on the basis of the questionnaires, aimed at Chemistry teachers and 12th grade students for the purpose of collecting information necessary for the compilation of the work. Analysis of the content of the interviews carried out with teachers and students demonstrates that the difficulties faced by teachers concern ׃ the lack of school laboratories in particular focus on natural science disciplines; to the advanced state of degradation of the few existing laboratories in the school concerned; the chronic problem of overcrowded classes, about 60 to 70 students in classrooms designed to accommodate 25 students; the lack of means didactic; indiscipline within students; the constant complaint that Chemistry programs for General Secondary Education are quite bulky and the burden hourly is quite reduced; also point out, the weak methodological preparation of some teachers in this work, among others. While some students complain and justify the difficulties due to the difficult structural conditions of the schools and the little or even lack of patience, vocation and willingness to teach on the part of some teachers, other students claim that chemistry classes in our schools are not contextualized, that is, it is not taught a Chemistry directed to the daily life, etc.
