The Active methodology of peer instruction associated with videoanalysis of kinematics experiences as an introduction to teaching function

As a result of studies for interdisciplinary applications developed under a Master’s Degree in Science Teaching, with the aim of orienting teachers and undergraduate students in Physics, Mathematics and related fields for innovative practices next to the student body, this study deals with the teaching of functions in classes of 9th grade of Elementary School, involving Mathematics and Physics, from the quasi-experimental delimitation of time series. By means of the videoanalysis of small kinematics experiments carried out by the students, using the free software Tracker, questions were treated about related and quadratic functions, derived from these experiments and observations, with pre-tests and conceptual tests of six double classes, intercalating the accomplishment of the physical experiments and the application of the tests. The videoanalysis of the kinematics experiments, with conclusions reached by the students, entered as an introductory factor and basis of the functions theme. The pre and post-tests were mediated by the active methodology of Peer Instruction and the exchange of understandings and experiences between the participating groups made possible the evaluation and measurement of the study regarding its effectiveness. The treatment was applied in three classes of a school of the Foundation of support to the Technical School of Rio de Janeiro, totalizing the participation of 76 students. The results of this research, obtained in the development of the activities, studied by the statistical analysis of Hake’s normalized gain under the quasi-experimental design, indicate the possibility of using the proposed active methodology as potential mediator of the teaching-learning relationship in collaborative contexts
