Abstract

This research aims to develop an interactive e-student worksheet on integers in the context of traditional South Sumatran games that is valid and practical. This research was carried out at SMP in Martapura class VII in the odd semester of the 2023/2024 academic year. This research uses a type of development research (Research and Development) using the ADDIE model but researchers only use three stages, namely Analysis, Design and Development. The validity of the interactive e-student worksheet is checked through 3 factors, namely construct, content and language contained in the validation sheet at the Expert Review stage and input or comments from the experimental results at the One to One stage. The practicality of interactive e-student worksheet is based on the results of questionnaire calculations given at the Small Group stage. The results of the research show that the development of interactive e-student worksheet has a validity of 95.3125% with very valid criteria and a practicality percentage of 86.25% which is classified as very practical

Abstract

Computational thinking is one of the most important skills in the 21st century; it is a thinking ability related to a set of mindsets that includes understanding problem-solving, reasoning at the level of abstraction, and developing problem-solving. This research is descriptive qualitative research that aims to determine the students' computational thinking ability and describe the computational thinking ability of 3 research subjects. The subjects of this study were 3 students selected from 28 students of class VII. The research instruments were test questions and interview guidelines. The results showed that out of 25 students, 14% were low-ability students, 75% were medium-ability students, and 11% were high-ability students. Students in class VII.1 were mostly able to fulfill the indicators of decomposition, pattern recognition, algorithmic thinking and abstraction, but only a few students who raised these indicators correctly

Abstract

This study aimed to describe the critical thinking processes of junior high school students in solving PISA-based algebra problems using the context of Palembang based on their prior ability levels. The study employed a qualitative descriptive approach with six students selected purposively and categorized into high, medium, and low ability groups. The instrument consisted of three PISA-type algebra problems. Data were analyzed based on mathematical critical thinking indicators, including interpretation, analysis, evaluation, inference, and explanation. The results showed that students with low ability only demonstrated the ability to understand problems, while students with medium ability reached the stages of analysis and reasoning but were not consistent in evaluation and conclusion. In contrast, high-ability students demonstrated all critical thinking indicators completely and systematically. Furthermore, higher cognitive levels of the problems affected students’ performance, where low and medium ability students showed a decline, while high-ability students remained consistent.
