Abstract

Learning chemistry about hydrocarbon compounds presents significant challenges for teachers, as many of the concepts taught are abstract, involve many ideas that need to be memorized, and are imaginative. The problem faced by students is the limitation in visualizing the form of hydrocarbon compounds, so it is necessary to develop media to train their visual intelligence. This was revealed from interviews with chemistry teachers at high schools in Surabaya and a pre research survey of eleventh grade students, which showed that visual intelligence related to hydrocarbons is still relatively low, with an average ability of only 44 percent. One media that is suitable for the characteristics of learning in the 21st century is interactive video. Based on the things that have been explained, this research developed interactive video media that integrates visual intelligence training on hydrocarbon compounds, with the aim of describing the feasibility of the developed media. The research and development (R&D) method used was a 4D model, but was limited to 3 development stages. A limited trial was conducted involving 20 eleventh grade students. The average visual intelligence score increased from 48 in the pretest to 88 in the posttest. The Wilcoxon Signed Rank test showed a significance value of 0.000 with an effect size (r = 0.89), indicating a significant improvement. Therefore, the developed interactive video media, which combines molecular visualization and provides direct feedback, can effectively support the visual process in understanding abstract chemical concepts.

Abstract

Thermochemistry is considered difficult because students need to connect abstract concepts, experimental observations, and calculation procedures in one learning process. Therefore, structured learning support that provides learning targets, feedback, and reflection is needed. This study focused on describing how students’ thermochemistry learning outcomes increased after the use of assessment for learning-oriented student worksheets. A pre-experimental approach using a one-group pretest-posttest design was carried out, with 24 students of class XI-B at SMA 1 Muhammadiyah Taman as participants. The learning process was carried out over two meetings covering system and surroundings, exothermic and endothermic reactions, thermochemical equations, calorimetry, and heat calculation. Data were collected through pretest and posttest, observation sheets for teacher and student activity, and student response questionnaire. The data were analyzed using rate (percentage) analysis, a normality test, the Wilcoxon signed-rank test, and N-gain. The findings indicated that teacher activity reached 91.54% and student activity reached 89.69%, both in the very good category. Students’ mean score improved from 60.94 to 85.83, indicating that the difference between the pretest and posttest results was significant. The N-gain result was categorized as medium with a mean score of 0.63, whereas students’ responses were categorized as very good with a rate of 97.92%. These results show that assessment for learning-oriented student worksheets can enhance students’ thermochemistry learning outcomes
