The Development of Sound Wave Audacity Base Learning Media Using Ethnoscience Approach of Amanuban Tribe to Improve Physics Teacher Candidates? Science Process Skill

This studi is aimed to developed teaching learning media of sound wave using valid, effective, and practical ethnoscience approach of Amanuban tribe. Research method used ADDIE approach R and D method. The implementation of teaching learning mediais done in limited scale try out to 27 student of Physics Education Program of STKIP SoE. Research design applied is one group pretest posttest design. The developed teaching learning media are students worksheet based ethnoscience approach of Amanuban tribe audacity and test of science process skill. The instrument use to collect the data are validation sheets, test of science process skill, and response questionnaire. The result of teaching learning media vallidation accomplish valid criterion in the aspects of organization, content, and language competence formula. The instrument of science process skill test is valid in content validity, performance validity, and construct validity aspects. The students positive response reaches 90 % so it is concluded that the teaching lerning media is practical in use. The result of paired t test gets t= 19, 082, pless than 0, 05 which means there is significant difference in students science process skill before and after the implementation of the media. The score of n-gain gets 0, 7 in high criterion. Therefore, teaching learning media of sound wave based on ethnoscience approach audacity is effective.
