Abstract

In general, this research aims to produce a valid magnetic induction experimental device as a medium for learning physics in high school. The experimental device consists of experimental equipment and tool usage manual. In particular, this research aims to design, build, and validate devices for magnetic induction experiments on coiled wire as a physics learning media according to the research development steps. Three experts and two physics teachers as users have been involved to provide an assessment of the experimental devices that have been built. Assessment is carried out on the construction and content of the experimental device. The results of data analysis showed that every aspect of the assessment of the experimental tool was declared valid with a very good category (index validity 3.34) and the manual for using experimental tools was also declared valid with a very good category (index of validity 3.47). Thus, it can be said that the magnetic induction experimental device in circular wire is declared valid as a medium for physics learning.

Abstract

Science education must be involved in direct experience. Therefore, student must study with finding problem method  not talkative method. Education’s module about vibration and wave in curriculum demand, must be accomplish with experient. Unfortunately, this method are difficult to use because the lack of experient tools to produce measured standing waves like velocity, amplitude, period and frequency. The purpose of this research to develop vibration’s simulation experiement tool. This research are belong to developing research type, because it was used to producing some products, and testing the effectiveness of a product. The experiment was following ADDIE model steps, which were consist of 5 steps to follow such as analysis, design, development, implementation and evaluation. The experiment tools could be used after validated by the expert. After the validation finished, the tools can be tested in the field. The validation result from experiment tools and Student Worksheets already passed the validation from the experts. After tested in the student’s groups, the result were positive and fulfill the criteria practical from students view. Therefore, the tools can be used widely to see its effectiveness.
