Abstract

Critical thinking is a process that involves thoroughly evaluating information to make sound decisions. This skill enables students to systematically analyze problems, address challenges in an organized manner, formulate issues, and develop effective solutions. According to PISA results, the average mathematics score of Indonesian students remains below the international average. One significant aspect of mathematics learning, particularly in the affective domain, is the habit of mind, which supports the achievement of education goals. This study aims to assess students’ critical thinking skills and describe the critical thinking processes of Islamic junior high school students in solving mathematical problems in relation to their habits of mind. A descriptive qualitative approach was employed. The subjects consisted of 48 eighth-grade students from an Islamic junior high school in Bandung, with the topic of relations and functions. Data were collected through critical thinking tests, habits of mind questionnaires, and interviews. The data were analyzed inductively to gain an in-depth understanding of students' critical thinking processes. The results showed that the average score of students’ critical thinking ability was 66%, which falls into the moderate category. Moreover, the critical thinking process in solving mathematical problems varied based on students' levels of habits of mind. Students with high levels of habits of mind. Students with high levels tended to demonstrate stronger critical thinking skills.

Abstract

This study investigates the impact of performance assessment tasks on mathematics learning outcomes, with particular attention to potential differences based on student gender. Employing a quasi-experimental design with non-equivalent control groups, 80 vocational pharmacy students in Bandung were divided evenly into experimental and control groups. The study aimed to evaluate whether performance assessment tasks improve mathematical knowledge, problem-solving strategies, communication skills, and attitudes toward mathematics, and whether effectiveness differs by gender. Data were collected through tests and questionnaires, then analyzed using descriptive and inferential statistics. Results showed that while the experimental group's scores improved compared to the control group, the difference was not statistically significant for either male or female students. The most notable finding was a strong association between attitudes toward mathematics and learning outcomes, particularly among female students (r=0.878, p<0.001). These results suggest that performance assessment tasks show promise as a learning strategy, though their effectiveness requires further validation. The findings highlight the critical importance of fostering positive student attitudes in mathematics instruction to enhance performance. Study limitations include the small sample size and short intervention period. The study underscores the need to design learning approaches that balance cognitive and affective aspects, particularly in vocational education contexts.

Abstract

This study aimed to develop and evaluate West Java tourism-based numeracy teaching materials designed to foster critical thinking among elementary school students. The study employed a Research and Development approach using the ADDIE model, comprising analysis, design, development, implementation, and evaluation. Needs analysis involved curriculum review, interviews, and questionnaires administered in three elementary schools. The product was developed for fourth- and fifth-grade students and consisted of a numeracy module, student worksheets, and a teacher guide integrating measurement, estimation, arithmetic operations, and simple data analysis with authentic contexts from Kawah Putih, Tangkuban Perahu, and Pangandaran Beach. Product validity was assessed by three experts in mathematics education, curriculum, and elementary education, while practicality was examined through teacher and student response questionnaires. A limited field trial involving 75 students used pre-test and post-test tasks to assess numeracy and critical thinking, supported by classroom observations. The expert validation yielded an overall mean score of 3.55 on a four-point scale, indicating that the materials were very valid. Teacher and student responses ranged from 85% to 90%, placing the materials in the very practical category. Post-test performance increased by 25% compared with pre-test performance, indicating meaningful gains in students’ numeracy achievement after using the materials. Students also demonstrated stronger abilities to identify relevant information, analyze quantitative relationships, evaluate solution strategies, and draw logical conclusions in contextual tourism problems. These findings indicate that the developed materials are valid, practical, and potentially effective for meaningful numeracy learning. Broader trials are recommended to examine their effectiveness across diverse elementary school contexts.

Abstract

Objective: This study aims to examine the effect of Digital Learning Management System (DLMS) implementation on educational efficiency and educational quality in educational institutions in Bandung City, Indonesia. The research is motivated by the growing need to evaluate DLMS not merely as a technological tool, but as a strategic educational management system that supports both operational efficiency and learning quality. Method: A quantitative explanatory research design was employed. Data were collected through a structured questionnaire administered to 210 educators and students who had actively used DLMS for at least one academic semester. The data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) to assess the measurement model (validity and reliability) and the structural model (hypothesis testing). Results: The results show that the measurement model demonstrates strong reliability and validity, with all constructs meeting the recommended thresholds for factor loadings, composite reliability, and average variance extracted. Structural model analysis reveals that DLMS implementation has a positive and significant effect on educational efficiency (β = 0.641, p < 0.001) and educational quality (β = 0.672, p < 0.001). These findings indicate that effective DLMS implementation enhances resource utilization, streamlines instructional and administrative processes, and improves learner engagement and instructional consistency. Novelty: This study offers novelty by integrating educational efficiency and educational quality within a single SEM-PLS analytical framework and by providing empirical evidence from an urban Indonesian context. Unlike prior studies that examine DLMS outcomes separately, this research positions DLMS as a strategic educational management system that simultaneously strengthens efficiency and quality in post-pandemic education.
