O PAPEL DA EXPERIMENTAÇÃO NO ENSINO DE CIÊNCIAS E A SUA CONTRIBUIÇÃO PARA A APRENDIZAGEM SIGNIFICATIVA

Abstract

This work relates the application of a Unit of Teaching Potentially Significant for the teaching of the concept of Photosynthesis in two 6º-year classes of a state public school in the city of Cantagalo (PR), in 2016. This Teaching Unit was elaborated with base in the presuppositions of Significant Learning Theory. The instruments used to collect data were: the activities performed by the students, application of pre and post-test in two 6ºyear classes using simulators. For the analysis of the data, was adopted a qualitative in which the semi-qualitative scale was used and the numbers refer to the addition of the "crosses" obtained from the Likert scale. The methodological referential adopted in this study, was the qualitative approach, and the most recent exploratory and interpretative results. The analysis of the activities and the evaluation questionnaire of learning showed an increasing process of acquisition of knowledge by the students worked in the Teaching Unit. The results obtained in the post-test of evaluation of instructional resources indicated that the use of experiments, videos and computer simulations contributed to arouse the interest students for content approached in the Teaching Unit. In this way, the results demonstrated that the Unit of Teaching Potentially Significant elaborated with base on the presuppositions of the Significant Learning Theory to introduce the concepts of photosynthesis contributed to create a motivating and stimulating environment for the student. The concepts worked in the Teaching Unit allowed students to expand their previous knowledge dynamically, without compromising the consistency of scientific phenomena in between the pedagogical instruments.
