Utilização de Experimento de Química: Uma análise das atividades propostas por professores da rede pública de ensino.

Abstract

Experimentation in chemistry teaching exposes the importance of practical lessons and differentiated approach to assists in the learning process. The chemistry is present in daily life, experimental classes with differentiated approach to teaching is the bridge between prior and wisdom the scientific wisdom, demonstrating that chemistry is embedded in all our usual. This study aimed to examine in what way the trial is being inserted in the discipline of chemistry in high school and your relationship with the content covered during the school year. The present research consists of a field work, empirical data, descriptive, qualitative in nature, in which will be analysed the formation, characteristics of the school environment and the methodology of high school teachers, as the contribution of experimental lessons learning in teaching chemistry. The survey was developed in 5 schools in the public school system in the cities of Remígio, Areia and Arara located in the State of Paraíba. The target audience were 10 Chemistry teachers who teach in high school classes of regular public schools. The proposal if it worked in terms of experimentation teaching of chemistry, collecting data since the drafting of the proposed curriculum, your development and data collected through the questionnaire and comments. The use of the trial takes place in the context of interest, motivation, training and availability of resources, are using these skills to develop them. From the results it is possible to notice that the teachers reflected the importance of experimental practices. The training of teachers is limited, as it is only required for the position, few teachers have had a continuous formation, giving the training time and relevance of teaching. The characteristic of the school environment in which teachers use specific methodology, 70% of schools does not contain Chemical Lab, so classes are conducted in the classroom, containing numerous difficulties, such as lack of materials and motivation. Schools containing laboratory, teachers reported about the excessive amount of students and lack of aid to meet the need to monitor students. It is concluded that teachers face and try to meet the need of numerous impossibilities faced to perform experimental classes.
