Abstract
Diffraction grating innovative media (DIAGRAM) is a physics experimental tool that can be implemented in the learning of diffraction grating material. This research endeavored to analyze conceptual understanding of students on diffraction grating material after using the diffraction grating innovative media (DIAGRAM). Pre-experimental design was used as the method in this research with one-group pretest-posttest as the design and 10 female students and 1 male students from three schools in Indonesia participated. Starting from interpretation test using multiple choices test consisting of 8 questions, the stage then carried out learning activity utilizing the DIAGRAM and given a posttest in the end of the class. At the last data had been analyzing by N-Gain. The come about of this consider were gotten by increment of students in moderate category. To sum up, diffraction grating innovative media (DIAGRAM) can make enhancement of conceptual understanding of senior high school students in diffraction grating material.
