Abstract

Low mathematical literacy among Indonesian students, as indicates by PISA results, highlights the need for innovative and contextual learning media that connect mathematics with real-life situations. This study aimed to develop and examine the feasility and praticality of E-Colands (Electronic Comic of Peatlands) as a mathematics learning medium for junior high school students in Central Kalimantan. The research employed a research and development method using the ADDIE model, limited to the Analysis, Design, Development, and Implementation stages. E-Colands was designed as a digital comic integrating matematical literacy tasks with peatland contexts encountered in students’ daily lives. Product feasibility was assesed through expert judgment by material and media experts using Likert-scale validition instruments. Practicality was evaluated through student response questionnaires administered to 75 students from grades VII, VIII, IX selected through purposive sampling. The results showed very high level feasibility, with validation scores of 91.25% form material experts and 89.29% from media experts. Students responses indicated good practicality, with an overall score of 80.49%, expecially in language clarity, media design, and ease of use. These findings suggest that E-Colands is a valid and practical learning medium to support contextual mathematics learning and enhance students’ mathematical literacy.

Abstract

This study aims to describe the improvement of mathematical creative thinking ability of seventh grade students through the application of an Open-Ended approach integrated with the Effective Questions strategy. The study focuses on four key indicators of creative thinking: fluency, flexibility, originality, and elaboration. A quasi-experimental method was employed in this research, using a pretest-posttest group design. A purposive sampling technique was used to select one experimental class and one control class. Data were obtained through creative thinking ability test and interviews which were then analyzed descriptively and statistically. Statistical analysis was performed through a one sample t-test and N-gain. The findings indicate that integration the Open-Ended approach with effective questions strategy significantly improves students’ creative mathematical thinking, with details that (1) fluency and elaboration indicators increased in the high category (0.91 and 0.81), and (2) flexibility and originality indicators increased in the moderate category (0.61 and 0.38).
