Enhancing conceptual understanding via Diffraction Grating Innovative Media (DIAGRAM)

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 analyse students’ conceptual understanding 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 which are in Banjaran, Pamarayan and Makassar participated. Starting from interpretation test using multiple choices test consisting of 8 questions and using google form, 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 analysed by N-Gain. The come about of this consider were gotten by students’ increment in high category which is 0,73. To sum up, diffraction grating innovative media (DIAGRAM) can make enhancement of senior high school students’ conceptual understanding in diffraction grating material.
