Mobile Learning Media Based on Science, Technology, and Society (STS) to Improve Science Literacy for V Grade SD Students

Abstract

This study aimed to analyze the need, feasibility, and effectiveness of mobile learning media based on Science, Technology, and Society (STS) in improving scientific literacy in fifth grade elementary school students. This study used research and development procedures that refer to the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research design used was "Quasi Experimental Nonequivalent Control Group Design" with research subjects at SDN Jombang as the experimental class and SDN Ngombol as the control class, totaling 56 students. The research instruments used were observation sheets, interview sheets, expert validation test sheets, written tests (pretest and posttest), and questionnaire sheets (questionnaire). The results showed that the media-based mobile learning (STS) was needed by students in learning. The feasibility of the media, according to the media expert validator, was declared very valid with an average percentage of validity reaching 95.54%, material expert validator 96.68% with very valid criteria. Meanwhile, the teacher's response regarding the practicality of the media obtained a score of 97.73%, with very practical criteria. Students' responses regarding the practicality of the media obtained a score of 89.74% with very practical criteria. The effectiveness of STS-based mobile learning media according to the calculation of the increase in scientific literacy of students in the experimental class was 42.27%, from an average score of 57.15 to 81.31 in the very good category. Meanwhile, the control class increased by 37.56%, from an average score of 52.80 to 72.63.) in the good category. Keywords: Mobile Learning, STS, Science Literacy.
