This research and development use a 4D development model that consists of 4 stages: 1) Definition, 2) Design, 3) Development, 4) Disseminate. The media validity of the diagram board was assessed by the media, material and language experts, the result obtained from the experts is an average of 91.1% with highly valid criteria based on the pick-up data. For the practicality gained from student responses at the one-to-one stage the pupil obtains an average score of 85.3% with highly practical categories, small group responses obtaining an average rating of 90.2% with very valid categories and for the effectiveness obtained from the test results the pupils obtain an average grade of 86.67% with very high categories
