Influence of a motion sensor on the understanding of graphs Jeanne Kriek

Abstract

Various technological tools have been used for improving science teaching and learning, but using it in a productive manner to improve the quality of learning is not easy. The aim of this study was to determine the influence of the go motion on the understanding of kinematic graphs by firstly evaluating the materials to establish if it is suitable for technology-supported inquiry activities and secondly determine if the frequent graphing misconceptions has been addressed. A single instructional experience utilizing the research-based tutorial materials is superior to a traditional quantitative laboratory experience for conceptual understanding and because this study was done during one lab session the third goal of this study was to find out if one lab can make a difference. The activities were evaluated using the Learning-for-Use (LfU) model and TUG-K was used as pre and post test. The class average increased with 13%. Data from the completed worksheets of the activities as well as the reasoning on the pre- and post tests were analysed to alleviate the confusion or conceptual understanding of the slope and height of lines, the areas under graphed curves and the symbolic representation of information.
