Abstract:
The aim of the R & D research was to create the alternative experimental equipment
dynamic electricity which is able to use in physics learning process of junior high
school students grade IX. The experimental equipment dynamic electricity was
developed by researcher consist of the measurement of filament conductor obstacle,
the electricity projectboard structure, and the guidance book. The alternative
experiment equipment had been validated based on its construction, the content, and
the practical test. Based on the data analysis, the data showed the validation of the
experimental equipment was 86.75% and the guidance book was 87.5% and the
validation of its construction was 82.5% that showed high category. From the
practical test showed the high category and the percentage was 85% for the
experimental equipment and the guidance book is 85%, then this experimental
equipment is suitable to use in learning process at the junior high school.
