O raciocínio hipotético-dedutivo e a experimentação investigativa no Clube de Ciências Prof. Dr. Cristovam W. P. Diniz

Abstract

The present study aims to analyze how Science Club participants develop the Steps and the Reasoning Pattern if / and / then / and or but / therefore proposed by Lawson, based on the Investigative Teaching Sequence on geometry with a group of children from 6th year of Elementary School in a Science Club. For this, we used the theoretical framework of Hypothetical-Deductive Reasoning and the Sequence of Investigative Teaching in Experimental Activities as a basis. This study has characteristics of Participant Research with a qualitative approach, the research locus was the Science Club Prof. Dr. Cristovam W. P. Diniz, the execution of the Experimental Activity took place between September 14 and 21, 2019, with the collaboration of three Teachers-Monitors and eight students. We used video recording, photography, audios and field notes as data constitution instruments, with subsequent transcriptions of the subjects' speeches, the aforementioned Pattern of Reasoning and the Steps that guide scientific research. In the results, we noticed that the groups developed the Steps and the Reasoning Pattern in their speeches, starting with the intriguing observations and ending with the conclusion of the problem, therefore. Thus, the results demonstrate the presence of Steps and the Reasoning Pattern in the students' speeches during the Investigative Teaching Sequence, pointing to the development of Hypothetical-Deductive Reasoning. Therefore, we conclude that the Reasoning Pattern proposed by Lawson is of great relevance to encourage students to produce their own knowledge from a problem to be solved.
