Resumo: |
This research correlate the chemistry of the daily life of the students, with the subjects and contents of the discipline of Chemistry of the second year High School at Cruz Alta, RS. The concepts of electrochemistry including redox potential, batteries, which are among the most difficult in student learning. In this work, we investigated the impact of contextualization, the use of experimental demonstration and discussion of relevant aspects as ways of arousing students' interest and favoring the learning of concepts of the content in question. The relevance of problematizing the different models and pedagogical epistemologies in the teaching of science is justified, since the conceptions of the educator and his praxis, involved in the teaching-learning process, are closely related to the quality of teaching and, consequently increasing the degree of understanding of the students. Thus, the research problem is presented: what are the effects of the use of different pedagogical models for teaching the concepts of chemical equilibrium and redox powers in the student learning process? In order to answer it, the general objective is to analyze the effects of two pedagogical models of teaching and evaluation on the content related to the chemical equilibrium and redox processes in batteries, regarding significant learning of students. With regard to the specific objectives: to provide an educational space/ time motivated by exchanges of knowledge, respect for students' previous knowledge and instigating the construction of knowledge in chemistry, based on scientific experiments. Based on a constructivist pedagogy, to produce an educational space/ time dense quantitatively in information of a theoretical nature, starting only with expository classes and with the use of lists to solve problems, based on a traditional pedagogy and To carry out a comparative analysis, with a qualitative and quantitative approach, in order to verify and understand the results, in students' learning, from the application of the different teaching models. The methodologies used as well as the methodological procedures characterize a qualitative and quantitative approach of the type of case study with the application of theoretical/ formal/ traditional evaluation and the resolution of a practical problem culminating in the elaboration by the students of a concrete and conceptual product about the subject. Data analysis was carried out comparatively between different teaching models, namely the traditional and the proposed in this work. All students said they liked the method and wanted to continue learning according to the same method in their school. |
