Abstract
This study is intended to explore the impact of using the ^Go-Chemist!^ app on students^ attitudes toward chemistry on colligative properties. This pretest-posttest quasi-experimental design study involved 70 twelfth-grade students at a public high school in Jakarta, Indonesia. One class was assigned randomly as a control group taught using printed books. Meanwhile, another class was assigned as an experimental group taught using the ^Go-Chemist!^ app. Students^ attitudes toward chemistry in both groups were then assessed before and after treatment using the Attitude Toward Chemistry Lessons Scale (ATCLS). To analyze the data, we employed independent and paired sample t-tests. The results of the analysis indicated that after the intervention, there was a significant difference in attitude scores between the two groups in favor of the experimental group. Students in the experimental group also showed a significant increase in mean scores from pretest to posttest. This reflected that the application of the ^Go-Chemist!^ app effectively increases students^ positive attitudes toward chemistry lessons on the topic of colligative properties. Due to its effectiveness in cultivating positive attitudes, the researchers then suggested to teachers take advantage of the ^Go-Chemist!^ app in chemistry learning.
