OS DESAFIOS EM UMA ABORDAGEM TEÓRICO-EXPERIMENTAL NO ENSINO DE QUÍMICA EM EAD

Abstract

Teaching of chemistry is complex, as it presents concepts considered abstract, generating a greater difficulty in its understanding. Some difficulties in teaching are also related to external factors, such as gaps in cultural formation and intrinsic and extrinsic motivation. In this aspect, the teaching of chemistry is challenging due to the difficulty encountered by students in the process of knowledge appropriation, however, when seeking to relate such concepts to the experimental area, this experience gives the student a more comprehensive knowledge of the content and the laboratory environment, which, in turn, directly influences students' scientific and cultural background. Therefore, in search of forming critical, participative and socially capable citizens to overcome the daily challenges present in society, practical experience in chemistry is relevant to student education. The Federal Institute of Goiano, institution of application of the project, has 3 technical courses integrated to high school, in addition to undergraduate courses as a degree in chemistry, presenting an environment conducive to the development of this research, aiming to analyze the effectiveness of a demonstrative-experimental approach in teaching chemistry, identifying the main difficulties and facilities encountered by students in the process of learning the discipline. From the aforementioned courses, which are face-to-face and, due to the COVID-19 pandemic, were adapted to EAD, 4 2nd year classes were chosen, 2 from the technical course in agriculture integrated into high school and 2 from the technical course in an environment integrated to the environment. high school, in which activities were implemented with an experimental approach linked to the students' daily lives through digital platforms and an interactive virtual environment. At the end of the proposed practices, the impacts on students' teaching-learning were assessed through exercise questionnaires, research involving students through a questionnaire with objective questions and their participation. In this sense, this research dealt with aspects considered relevant to the teaching of chemistry, with the use of an experimental pedagogical mediation within the distance learning modality, approaching a new perspective with a focus on the current reality of the classes.
