Abstract

Students' level of creativity influences their creative thinking processes. Students with different levels of creativity tend to demonstrate variations in how they approach creative thinking. This study is a qualitative research with a descriptive approach, aiming to describe the creative thinking processes of junior high school students in solving open-ended mathematical problems. The subjects of this study consisted of three students: one with a highly creative thinking level, creative thinking level, and moderately creative thinking level. Data were collected through written tasks involving mathematical problem solving and follow-up interviews. The results revealed that the student with a highly creative thinking level demonstrated strong abilities in integrating various sources of information, generating ideas independently and flexibly, and producing accurate solutions. The student with a creative thinking level was able to construct and plan ideas effectively but tended to use familiar strategies without further exploration, resulting in correct yet less innovative solutions. Meanwhile, the student with a moderately creative thinking level was only able to generate a single, simple idea, used familiar strategies without systematic planning, and produced inaccurate solutions while lacking the ability to evaluate the outcomes effectively. The results of this study can be implemented in mathematics learning by providing students with opportunities to develop their creative ideas through open-ended problems, encouraging the exploration of various problem-solving strategies, and creating a learning environment that values original and flexible thinking processes.

Abstract

This study aimed to develop and evaluate Computer Science Unplugged (CS Unplugged)–based student worksheets to enhance second-grade students’ understanding of number concepts. This study employed a Research and Development approach using the ADDIE model and involved 26 second‑grade students in a limited practical trial. The developed worksheets were evaluated through expert validation, practicality testing based on teacher and student responses, and effectiveness testing using a one-group pretest–posttest design. The results indicated that the worksheets achieved a very high level of validity (media: 92.67%; content: 91.67%) and practicality (students: 91.38%; teacher: 90%). The effectiveness test showed a substantial improvement in students’ learning outcomes, with the mean score increasing from 67 in the pretest to 90.38 in the posttest, and an N-gain score of 0.73, categorized as high. These findings demonstrate that CS Unplugged–based worksheets are valid, practical, and effective for improving students’ understanding of number concepts while supporting the integration of computational thinking in elementary mathematics education.
