Abstract

Science education at the junior high school level requires an approach that maximally develops students' science process skills (SPS). One way to achieve this is by utilizing interactive learning media, such as virtual laboratories, combined with an inquiry-based learning model. This study aims to determine the effect of implementing an inquiry-based virtual laboratory on improving students' SPS. The method used in this study is pre-experimental with a one-group pretest-posttest design. The subjects in this study were 32 students from class VIII D at SMP Negeri 4 Yogyakarta. Data collection was carried out by administering a pretest before treatment and a posttest after treatment. The data obtained were analyzed using paired t-test and N-Gain test. The paired t-test results showed a significance value (2-tailed) = (0.00) < 0.05, indicating the effect of the treatment on students' SPS. The N-Gain result was 0.73 in the high category, so it can be concluded that applying virtual laboratory media with the inquiry-based learning model in the inclined plane topic can enhance students' SPS in science subjects.

Abstract

Purpose – This research aims to find out:  (1) the effectiveness of using mini solar panel props with guided inquiry models to improve students' science literacy, (2) whether there is a difference in the average score of significant improvement in students' science literacy before and after the implementation of mini solar panel props with guided inquiry models, (3) how much the effect size of using mini solar panel props with guided inquiry models to improve students' science literacy.Methodology – This is a pre-experimental study that used a one-group pretest-posttest design. The study population included all students in class VIII of a junior high school in Yogyakarta. The purposive sampling technique was used to select the sample, which included 31 students from class VIII B. The instrument used was a science literacy test, while data analysis was conducted using descriptive and inferential statistics.Findings – The results of the analysis concluded that 1) mini solar panel props with guided inquiry models effectively improve students' science literacy by 0.55 in the medium category, 2) there is a difference in the average score of significant improvement in students' science literacy before and after the implementation of mini solar panel props with guided inquiry models, 3) the implementation of mini solar panel props with guided inquiry models provides an effect size of 2.19 with a huge category on improving science literacy.Contribution - These findings are expected to improve science education by integrating mini solar panel props with guided inquiry models, making science learning more interesting, practical, and relevant to real-world applications.
