The present study investigated effective methods of teaching tool-using skills to junior high school students. Students participating in the study were having difficulty using tools. The relative effectiveness of 3 types of instruction for helping the students improve working skills was analyzed by a comparison of 3 groups of participants. In the first method, 21 students were told how to use the claws of a hammer, and given a demonstration. In the second method (22 students), charts and pictures illustrating the laws of leverage were explained simply, and a demonstration was given. The third method (21 students) included the second method plus immediately having the students practice pulling nails. When the 3 groups were compared, the results showed that participants in the third group improved their skills the most. This group was also able to transfer the skill to other tools that use the laws of leverage, such as a sheet metal cutter, even though the appearance of those tools is quite different from the tool the participants were trained on. The explanation of the laws of leverage was effective, but immediately allowing the students to work with actual tools was an even more effective method of instruction.
