O ensino de química: uma análise sobre a importância da experimentação nas aulas de química do ensino médio

Abstract

The following research shows an analysis about the value to introduce experimental chemical class joint of contente presentes into the classroom to create a connection with theory and practice, where the teacher can show the bond between study approached with a daily students class. The experimentation in the process of teaching-learning comes often used to show one science and/or chemistry less absent for who is learning, the practice classes works as visualization method and testify the theory and concepts as support for cheer up and excite the students turning something such attractive and which make more students cleaver in to the process of investigation. Heading this goal research, we aim for the main difficulties faced for the teacher in the execute process practice in their classroom, and also na outlook of students about the practice class of chemistry instruction. This research has explorer feature with emphasis on qualitative analysis. It was used as the methodology a quis for the students of a public high-school in Manaus, where was asked about their ideas about experimental class and leaving their opinion for those classes. Many schools presente a lack of solid place and materials for the experiments practice, by the way many teachers talk about the lack of time for for this kind of exercise and the crowded classroom. However, we can determine that for a good mode to get concentrate students to have a teaching process is because of effectiveness of experiments which can bring more easily to the classroom and reply at home, mainly in the application of experiments with low cost materials
