The construction of physics laboratory i learning kits on sound velocity finding by resonance method

Abstract

The purpose of this research was to construct experimental learning kit on sound velocity finding by resonance method in order to use for a material in Physics Laboratory I. The instruments used in this study included : 1) an experimental learning kit on sound velocity finding by resonance method with the experimental manual and the record forms, 2) the pre-studying and the post-studying forms, and 3) the questionnaires about students satisfaction in using the kit. The samples consisted of 32 first year students studying in the faculty of Engineering and Architecture. The results showed that the post-test have the higher significant than the pre-test score at level of 0.05. It was found that the sound velocity from both the theoretical and the experimental framework did not significantly different at the level of 0.05. The end correction by experiment higher significant than by calculation at level of 0.01 and students were highly satisfied in using the invented kit.
