Abstract

This research aimed at the following objectives: (1) to design and develop a learning media set on sound waves and light using a smartphone sensor as a measuring tool based on the engineering design process for STEM education learning management; (2) to evaluate the efficiency of the learning media set on sound waves and light using a smartphone sensor as a measuring tool based on the engineering design process for STEM education learning management; and (3) to trial and evaluate the use of the learning media set on sound waves and light using a smartphone sensor as a measuring tool based on the engineering design process for STEM education learning management. The population and samples used in the trial use of the learning media set were 1) 4 physics teachers from School A and 4 from School B; 2) 12 student teachers; and 3) 50 high school students from School A and 45 from School B. The research instruments consisted of the learning media set on sound waves and light using a smartphone sensor as a measuring tool based on the engineering design process for STEM education learning management, the teacher’s manual and learning activity record sheets for the learning media set, the learning media set efficiency evaluation form, and the learning achievement test. The statistics used in the research were mean, standard deviation, t-test, and the normalized gain.

The research found that: 1) Learning media set on sound waves and light using Smartphone sensors as measuring tools according to the engineering design process for organizing learning according to STEM education guidelines which developed in this research can be used to measure various variables and parameters that need to be studied with accuracy and precision. 2) The results of evaluating the effectiveness of the learning media set on sound waves and light using Smartphone sensors as measurement tools according to the engineering design process for organizing learning according to the STEM education approach, found that, it was appropriate at a high level, consisting of essential content/learning content, and methods for measuring and evaluating learning outcomes with target groups and is most appropriate, consisting of learning objectives Learning activities with competency-based learning. The Learning equipment set and manual and learning activities. The total average evaluation score was 4.55, and the standard deviation was 0.512, which is in the highest quality criteria. 3) Learning achievement of organizing learning with learning media sets on sound waves and light. For learning management according to the STEM approach, after class was significantly higher than before class at the .05 level. The normalized gain for the physics content teachers at School A had higher (<g> = 0.73, <g> = 0.81) than physics content teacher of School B (<g> = 0.67, <g> = 0.79). Student teachers had normalized gain on the light topic (<g> = 0.68) than the sound wave topic (<g> = 0.67), and students of School A had higher normalized gain (<g> = 0.68, <g> = 0.66) than students of School B (<g> = 0.61, <g> = 0.59), respectively.
