Abstract

Numeracy literacy is a critical competency in mathematics education, but students often have difficulty understanding the concept of fractions contextually. This study aims to develop Student Worksheets based on Contextual Teaching and Learning (CTL) to improve numeracy literacy in fractions at the junior high school level, emphasizing the integration of real-life contexts and curriculum relevance. This study uses the Design Research method with the Tessmer formative evaluation approach, involving 28 seventh grade students of MTs YPNH Tanah Abang, Palembang. The stages include needs analysis, prototype design, expert validation (materials and media), and gradual trials (one-to-one, small group, and field test). Data were collected through questionnaires, interviews, and learning outcome tests, analyzed qualitatively-quantitatively to assess the validity, practicality, and effectiveness of the student worksheets. The results of the study stated that the student worksheets were declared valid based on expert assessments and very practical according to student responses. The effectiveness of the student worksheets was proven by the average class value which was included in the "Very Good" category and the high percentage of learning completion. Analysis of students' answers showed an increase in students' ability to apply fraction concepts in authentic contexts, such as visual data analysis and predictions based on quantitative information. This study contributes to the selection of CTL-based student worksheets in improving students' numeracy literacy through real problems and empirically valid structured frameworks, in accordance with the principles of the Independent Curriculum.

Abstract

Critical thinking skills and sustainability awareness are essential competencies for addressing global challenges in the 21st century. However, students in Indonesia still demonstrate relatively low levels of both competencies. This study examines the effect of the Concept Attainment Model (CAM) based on Education for Sustainable Development (ESD) on the improvement of students’ critical thinking skills and sustainability awareness in ecosystem learning. A quasi-experimental design with a non-equivalent control group was employed, involving two tenth-grade classes at one public high school in East Lampung, Indonesia (experimental group, n = 28; control group, n = 29). Data were collected through pretests, posttests, and sustainability awareness questionnaires. Data were analyzed using normalized gain (N-gain), independent samples t-test, and effect size (Cohen’s d). Results showed that the experimental class achieved higher improvement in critical thinking skills than the control class, with moderate N-gain values (0.47 vs 0.37) and a large effect size (d = 1.12. Sustainability awareness improved more substantially in the experimental group than in the control group, with emotional awareness achieving a high N-gain (0.89 vs 0.52), behavioral and attitude awareness showing moderate improvement (0.61 vs 0.27), and sustainability practice awareness demonstrating lower but still higher gains in the experimental class (0.51 vs 0.31. These results indicate that the integration of CAM with ESD effectively enhances both cognitive and affective domains of learning. The study highlights the potential of this approach for fostering competencies that are critical to sustainable education and suggests its application across various subjects and educational levels.

Abstract

The integration of digital learning media in biology instruction is increasingly important for enhancing students’ higher-order thinking skills, particularly in topics that involve abstract concepts and complex terminology, such as plant reproductive systems. This study aimed to develop and evaluate the feasibility, practicality, and effectiveness of a crossword puzzle-based e-module using Eclipse Crossword to improve the critical thinking skills of Grade IX students at Madrasah Tsanawiyah Negeri 01 Bandar Lampung. Employing a Research and Development design adapted from Borg and Gall, the study involved expert validation, readability testing, student response analysis, and an effectiveness test using a pretest–posttest control group design. Data were collected through validation sheets, questionnaires, observation, documentation, and critical thinking tests, and were analyzed using percentage scores, N-Gain, paired sample t-test, and independent sample t-test. The results showed that the developed e-module was highly feasible, with validation scores of 89.3% from media experts and 91.7% from material experts. The readability test indicated that 90% of students perceived the module as clear, engaging, and easy to use. The effectiveness test demonstrated a significant improvement in students’ critical thinking skills, with the experimental class achieving a higher posttest mean score than the control class and a moderate N-Gain score of 0.4403, compared with 0.1371 in the control class. Students also responded positively to the module, indicating that it was interactive, challenging, and helpful for understanding biological concepts. These findings imply that Eclipse Crossword-based e-modules can serve as an innovative and practical digital learning medium to support critical thinking development in biology learning.
