The research method used is a Research and Development (R & D). This research resulted in the kit and worksheet alternate light and optics to students of SMP/MTs. Developed experimental device has been tested for feasibility through empirical testing and validation. Data analysis techniques used in this study is a descriptive analysis, by calculate the index of each indicator instrument experiment. Instruments of analysis, indicated that the alternative kit with light and optical worksheet has been fit for use as a medium of learning that may show light symptoms.en-USExperimental device,the alternative light and optics kit,worksheets of light and opticsstudent Paper Post Degree
