The research showed that the INoSIT model student worksheets fell into valid and reliable categories. For the limited and extensive trials, the n-gain <g> analysis results on measures of science literacy, like being able to explain scientific phenomena, were 0.632 and 0.712, respectively. This means that they were in the moderate to high category. Furthermore, regarding evaluating and designing scientific inquiries, the average normalized gain was 0.541–0.580, indicating an intermediate category. Similarly, on the indicators of interpreting data and scientific evidence, the average normalized gain was 0,510-0,572, indicating a moderate category. Based on this data, the INoSIT model student worksheets were considered practical and effective in improving the scientific literacy competence of junior high school students
