The Performance Of NGSS-Based Teaching Materials Integrated Game Discovery (BANDI) On Senior High School Students Scientific Literacy Skills

Abstract

Scientific literacy is an essential skill to meet 21st-century challenges, necessitating its facilitation in educational settings. At the senior high school level, scientific literacy can be enhanced through NGSS-based teaching materials integrated with game discovery (BANDI). This study aims to analyze BANDI's performance in facilitating students' scientific literacy improvement. The research adopts a quasi-experimental design with a Nonequivalent Pretest-Posttest Control Group. The sample comprises 50 class X IPA students from SMA 01 Labuhan Haji, selected through cluster random sampling. BANDI's performance is evaluated based on its practicality and effectiveness. Practicality data were collected through observations and questionnaires, while effectiveness was assessed using a scientific literacy test adapted from PISA. Practicality data were analyzed descriptively, while effectiveness data were analyzed using statistical tests, including homogeneity, normality, Mann-Whitney, and Independent T-test. Results indicate that BANDI's practicality was validated through high implementation ratings and positive responses from students and teachers (75%-96.88%, 81.86%, and 88.39%). Effectiveness was confirmed via N-Gain analysis, showing a moderate improvement in the experimental class (0.51). Hypothesis testing further demonstrated significant differences in scientific literacy outcomes between the experimental and control classes (p < 0.00), with the experimental class achieving a higher average score (63.87) than the control class (38.70). Therefore, BANDI is effective in improving scientific literacy in terms of both practicality and effectiveness.
