Abstract

In learning chemistry, especially regarding quantum numbers and electron configurations, learning difficulties are still encountered, resulting in low student learning outcomes. One of the factors contributing to this is the use of teaching materials that are less engaging and fail to facilitate students' understanding of concepts effectively. Digital-based student worksheets are an innovative alternative to learning because they can increase students' interaction, understanding of concepts, and critical thinking skills. This research aims to apply problem-solving-based digital student worksheets to improve students' critical thinking skills and learning outcomes. This research employs a quantitative approach with a quasi-experimental design, utilizing a post-test-only control group design. The research sample consisted of 72 class X students at SMA Negeri 5 Banda Aceh. The results showed that the use of digital student worksheets significantly increased students' critical thinking skills (average score of 86.96) and learning outcomes (average score of 85.3) compared to the control group (critical thinking score of 80.20 and learning outcomes of 80.33). Students demonstrated a positive response to the use of digital student worksheets, with an average questionnaire response value of 83.53. The conclusion of this study indicates that the use of digital student worksheets can enhance students' critical thinking skills and learning outcomes. The contribution of community service from this study is manifested in the provision of innovative teaching tools that teachers can adopt to improve collaborative learning and support the development of digital literacy in the school environment.

Abstract

Chemistry is often considered a difficult subject for learners due to its abstract concepts and complex terminology. This can lead to difficulties in understanding the material and a decrease in students' interest in studying chemistry. The aim of this research is to describe and explain the factors of difficulty understanding in solving chemistry material experienced by students. The research method used is descriptive qualitative. The results show that 62.3% of students experience slight difficulty and 37.7% experience moderate difficulty in understanding chemistry material. The interest in learning chemistry of class XII MIA students is categorized as sufficient with a percentage of 46.68%. Factors causing difficulties in understanding chemistry material include a lack of understanding of mathematical concepts, the predominance of lecture methods, limited learning media, and the suboptimal use of chemistry laboratories. The conclusion of this research provides an overview that the factors causing difficulties in understanding chemistry material affect students' interest in learning. Therefore, these findings can be used as evaluation material to improve the quality of chemistry education in schools.
