Abstract

This study aims to develop and assess the feasibility level of Genially-based interactive learning media that integrates computational chemistry into chemical bonding materials. The media is designed to be able to display a more concrete visualization of molecular structures, so that it can help students understand abstract concepts. This research is included in the type of Research and Development (R&D) with reference to the ADDIE development model. The instruments used include media validation sheets and material validation sheets that are prepared based on the standards of the National Education Standards Agency (BSNP) and assessed by experts, as well as questionnaires to find out student responses. The results of the needs analysis at SMA Negeri 13 Medan show that the use of technology by teachers in learning is still not optimal, so students tend to feel less interested and have difficulty understanding the material. Based on these conditions, Genially learning media based on computational chemistry on chemical bonding materials was developed as a solution to support students' learning needs. The validation results showed that the developed media obtained an average feasibility percentage of 92% from media experts and 89% from material experts. Meanwhile, student response to this media reached an average of 87%. The final product of this research is in the form of interactive digital learning media. Thus, it can be concluded that Genially's learning media based on computational chemistry on chemical bonding materials is included in the category of being very feasible to be used in the learning process.

Abstract

This study was motivated by the low level of students’ motivation and learning outcomes in chemical bonding material at SMA Negeri 13 Medan, as indicated by low participation, limited conceptual understanding, and many students not achieving the minimum learning criteria. This study aimed to examine the effect of Genially-based computational chemistry media on students’ learning outcomes and to describe students’ learning motivation after its implementation. This research employed a quasi-experimental method with a pretest–posttest control group design. The sample consisted of 70 students, divided into an experimental class (n = 35) and a control class (n = 35). The experimental class was taught using Genially-based computational chemistry media integrated with discovery learning, while the control class used discovery learning without the media. The data were analyzed using N-gain and an independent sample t-test. The results showed that the experimental class achieved a higher increase in learning outcomes (N-gain = 0.72, high category) compared to the control class (N-gain = 0.63, medium category). The hypothesis test indicated a statistically significant difference between the two groups (t (68) = 3.74, p < 0.05). In addition, students’ learning motivation in the experimental class was categorized as high (81%). In conclusion, Genially-based computational chemistry media has a significant effect on improving students’ learning outcomes and positively contributes to students’ learning motivation. Therefore, this media can be used as an innovative alternative in chemistry learning, particularly for abstract topics such as chemical bonding.
