Chemistry Acoustic (Chemcoustic): Android Based Application for Fun Chemistry Learning

Learning media are used to facilitate educational practices, both in terms of administration and as a tool in teaching and learning activities. Music and dynamic images are effective stimulants of the brain's work in developing eidetic intelligence, remembering visual information with high-level photographic accuracy. Making Chemcoustic application as audio visual media aims to develop students' learning abilities in understanding chemical concepts based on chemistry representations, by utilizing Android-based technology. The making of the application is carried out with the design stages of the application design in terms of the display, content, and lyrics of chemical songs, making music arrangements, song validation, application making, testing, and evaluation. The trial was conducted on 40 fresh graduated high school students using C1-C4 type test instruments in the form of pre-test and post-test. Based on the t-test quantitative analysis, the calculated t value is greater than the t table value, and the average gain score of the post-test (52.8975) is much greater than the average gain score pretest (15.68). Qualitative observation shows that learning using Chemcoustic applications is conducive, enthusiasm and activeness of students increases significantly. Chemcoutic application is effective as a medium of chemistry learning, as well as science learning that demands complex concepts with macroscopic, sub-microscopic, and symbolic representations.
