A proposal for Inquiry-Based Teaching Sequence about momentum, its conservation and Newton's laws

Abstract

Aiming to contribute to the improvement of Physics teaching, which goes through a crisis reflected by very small demand for courses in exact Sciences, we propose an Inquiry-Based Teaching Sequence (IBTS) planned to develop argumentative situations, i.e., essential activities in the learning process. Initially we show the scientific argumentation, the specific characteristics (or dependent field) we intend to potentialize: seriation, sorting and organizing information, survey and hypotheses test, justification, explanation, prediction,    abduction,    deduction,    induction,    logical    and proportional reasoning. Then we discuss what constitutes such teaching proposal, involving the formulation of a problem and the elaboration of hypotheses from the conceptions of students to its resolution, coming to the verbal language passage for the Science one. Finally, we explain the sequence of activities. We focus on a subject rarely discussed in High School classes, which is the linear momentum  and  its  conservation,  and  based  on  this  study,  we introduce activities for Newton's laws teaching. We propose the use of inquiry experiments, issues and inquiry problems and texts during the classes.
