Connecting the Hands-on to the Minds-On: A Video Case Analysis of South African Physical Sciences Lessons for Student Thinking

Abstract

Background:In South Africa, there is a strong curriculum imperative for school science teachers to not only involve learners in practical inquiry activities but also to support students in making a connection between the construction of substantive scientific knowledge to these activities. The research reported in this article investigated the extent to which South African teachers at historically disadvantaged township schools engaged students in the construction of science ideas in inquiry lessons.Materials and methods:To this end, video transcripts of thirty two lessons were analysed and coded using a framework of student thinking lens developed by the Biological Sciences Curriculum Study (BSCS) for the Science Teachers Learning from Lesson Analysis (STeLLA) project. The trends on the teaching features are explicated in the presentation of an in-depth analysis of a chemistry lesson.Results:The findings on the analysis of the thirty two lessons reveal that these teaching features are poorly manifested in the lessons, and it is concluded that teachers only weakly make visible student thinking in inquiry lessons.Conclusions:This research suggests the need for a re-alignment of inquiry-based science education with the development of science ideas.
