Como age a pressão atmosférica? Algumas situações-problema tendo como base a história da ciência e pesquisas na área

Abstract

The aim of this article is to present the results of a series of problem-situations on the subject "atmospheric pressure", which were answered by Physics teachers-to-be during their training program. Those activities, which could be developed with Elementary School Students and/or High School Students, have as their basis the active participation of the students in the learning process. The arrangements of the activities result from some data found through researches carried out on the subject, besides some occurrences in the History of Science and the activities have two main axis, which take as starting points some obstacles students have to overcome in order to understand some phenomena related to atmospheric pressure. In each activity, the main types of answers obtained from the Physics teachers-tobe are presented. From the results some strategies to be used by teachers, while developing the subject, are pointed out. (English) [ABSTRACT FROM AUTHOR]
