Development and Effectiveness of Multiple Pulley Experiment Using Block Toys in Lower Secondary School Science Learning

Abstract

The purpose of this study was to facilitate experiments using multiple pulleys and to measure the effect of utilizing block toys in lower secondary school science learning. As a result of using block toys, the strings did not come off the moving pulleys, and various patterns of experiments using multiple pulleys could be easily conducted. In addition, the new system using block toys can be manufactured at a lower cost than conventional pulleys, making it easier to obtain and adopt into science classes. As for the effect of the experiment, in the case of complex patterns with multiple dynamic pulleys and strings connected to the pulleys, the students’ understanding of how to identify the dynamic pulley, as well as how the magnitude of force and the distance to pull the string change, was deepened in comparison to the baseline case without using the dynamic pulley system with the block toys.
