Article Information Background: Understanding the relationship between students' thinking styles and their numeracy literacy, especially in solving Higher Order Thinking Skills (HOTS) questions, is essential in educational research. Aim: This study aims to explore how students' thinking styles influence their numeracy literacy in addressing HOTS-based questions. Method: A descriptive qualitative approach was employed in this research. The study involved eight students from Larangan 1 Public Middle School, selected through a thinking style questionnaire. Two students were chosen from each of the four identified thinking style categories. Data were collected using tests comprising two HOTS-based questions and interviews. Results: The findings indicate that students' numeracy literacy varies significantly according to their thinking styles when solving HOTS questions. Students identified as SK and SA exhibited higher numeracy literacy, effectively utilizing various symbols and numbers, analyzing tabular information, and interpreting these analyses to make decisions. In contrast, students labeled as RK were only able to fulfill two numeracy literacy indicators and struggled with information analysis. RA students faced challenges in correctly writing numbers or symbols, analyzing information, and articulating problem-solving processes and conclusions. The study also found that students who process information sequentially exhibited better numeracy literacy in solving HOTS-based questions. Conclusion: The study concludes that students' thinking styles play a crucial role in their numeracy literacy, particularly in solving HOTS-based mathematical problems. This insight underscores the importance of considering individual cognitive styles in educational strategies to enhance mathematical problem-solving skills.

This study aims to produce valid and practical digital-based LKPD on ecosystem material for junior high school students. This type of research is research and development. The media development design used is the 4-D (Four-D) model, namely define, design and development, and disseminate. However, this study was modified and limited to reaching the 3-D stage because the media developed was only to test the feasibility of the LKPD media. The subjects in this study were nine students of CLASS VII SMP. The instruments used include validation sheets and questionnaires. The study results show that the developed digital-based LKPD is valid as a student learning tool with an average percentage of 79.25%. The results of the student response questionnaire got 87.5% in the positive category. Using the developed LKPD can significantly increase students' interest in learning and improve learning outcomes.
