Abstract

This research is motivated by the low critical thinking skills of students in chemistry learning. This is indicated by students who have not been trained in analyzing a problem and a lack of involvement, so that students are not motivated to learn. Students need effective teaching materials to be actively involved in analyzing problems and motivating learning, so that E-LKPD based on Socio-Scientific Issues is expected to be a learning innovation. This study aims to measure the effectiveness of E-LKPD based on Socio-Scientific Issues in acid-base learning on critical thinking and student learning motivation. E-LKPD is presented via the web Liveworksheets as an interactive medium. The type of research used is a quasi-experiment with a nonequivalent group pretest-posttest research design. The study was conducted in class XI IPA 8 and XI IPA 1 SMAN 4 Pekanbaru consisting of 90 students. Data analysis used the Normality test, t-test, and N-gain test. The results of the analysis for critical thinking obtained an N-gain of 0.6586 in the control class and 0.7509 in the experimental class. Meanwhile, for learning motivation, the N-gain obtained was 0.2537 in the control class and 0.4548 in the experimental class. Furthermore, the results of the t-test showed that there was a significant difference between critical thinking skills and learning motivation in the control class and the experimental class. Critical thinking skills and learning motivation have a positive relationship as evidenced by the sig. value < 0.05 with a Pearson correlation value of 0.419, thus E-LKPD based on Socio-Scientific Issues is effective in improving critical thinking skills and learning motivation in acid-base learning.

Abstract

Electronic Student Worksheets (e-Student Worksheets) include teaching materials that are intensively developed to facilitate their learning process. One website with many features that can be utilized to create E-Worksheet is Liveworksheets. This study aims to develop an E-Worksheet based on the Attention, Relevance, Confidence, and Satisfaction (ARCS) model on the subject of acid-base that is valid and knows the user response. The research method used is Research and Development (RD) with the 4-D development model. Research instruments in the form of validation sheets were given to 3 validators, and user response sheets were given to 2 chemistry teachers, 10 students from a Senior High School A in Pekanbaru, and 10 students from a Senior High School B in Pekanbaru, Indonesia. Material expert E-Worksheet validation obtained a total average score of 97.3% with valid criteria and media expert validation obtained a total average score of 100% with valid criteria. User response obtained results with an average score of 95.3% from teachers and students of 89% with very good criteria. From the research results, it can be concluded that the ARCS-based E-Worksheet using Liveworksheets on acid-base material can be used as teaching materials in the learning process.
