Interactive multimedia sound and light waves integrated STEM to develop concept understanding and literacy skills of students

The rapid development of technology in the Industrial Revolution 4.0 has made it necessary for students to master technology and have data literacy and technology literacy skills. However, initial studies show that the data and technology literacy of grade XI high school students is still relatively low. This study aimed to investigate the effectiveness of STEM-integrated light and sound wave interactive multimedia in improving students' concept understanding and literacy skills. The type of research used was a pseudo-experiment with a posttest-only control group design. The subjects of this study were 70 grade XI pupils who were divided into experimental and control classes. The sampling used was cluster random sampling so as to obtain two sample groups with the same ability. The instruments used were written tests for knowledge aspects and performance assessments for data literacy and technology aspects. The collected data were analysed using independent sample t-test and z-test. The results of the analysis showed that the knowledge, data literacy, and technology literacy skills of the experimental class were higher than the control class. This can be proven from the t-test value on knowledge which is 4.696>1.995 respectively, t-test on data literacy which is 9.906>1.995, and z-test on technological literacy z=-7.22>1.96. The results of this study suggest that students' knowledge, data literacy, and technological literacy increase using STEM-integrated Physics interactive multimedia. Following up on the findings of this study, the use of STEM interactive multimedia should be optimized to develop students' data and technological literacy.
