Abstract
This study aims to investigate the effect of using the ^Go-Chemist!^ on students^ self-efficacy regarding chemistry and technology on the topic of hydrocarbons. This study used a quasi-experimental pretest-posttest design. The respondents were 72 students (25 boys and 47 girls) at a public high school in Jakarta, Indonesia. Students in the experimental group (n=36) were instructed to use the ^Go-Chemist!^ app and students in the control group (n=36) were taught using printed textbooks. All students in both groups completed the Self-Efficacy Scale towards Science and Technology (SESST) before and after the intervention to measure their level of self-efficacy on the topic of hydrocarbons. Independent and paired sample t-tests were used to analyze the difference and increase in scores between the experimental and control groups. The results showed that students in the experimental group were superior and there was a significant increase in the mean score compared to the control group in terms of self-efficacy. Based on the findings, we recommend teachers and students use the ^Go-Chemist!^ app to promote students^ self-efficacy toward chemistry and technology on the topic of hydrocarbons to a satisfactory level.
