Abstract

The aim of this research is to develop an assessment instrument for problem-based Phase B science learning that is valid, practical and effective for measuring the critical and creative thinking abilities of students in elementary schools. This type of research is Research and Development (R&D), with development design referring to Borg & Gall theory. The population in this study was class IV students at SDN 4 Bumi Waras Bandar Lampung. Data collection tools use valid and reliable test instruments. The final average validation results from material experts, evaluation experts and language experts obtained a score of 87.75% with very valid criteria. The test results for the educator practitioners were 83% and the students were 82% with very practical criteria. The data analysis technique uses the One-Sample Z-Test to determine the correctness of the results of the assessment scores with a significance level of 95% (α 0.05), with a significance value of 0.023 obtained, indicating that the sig. value < 0.05 means H0 is rejected and H1 is accepted, so Effective assessment instrument for measuring students' critical and creative thinking abilities in elementary schools. Based on this research, it can be concluded that the assessment instruments for problem-based science learning are valid, practical and effective for measuring the critical and creative thinking abilities of students in elementary schools.

Abstract

Elementary science learning requires contextual materials that help students understand scientific processes and develop environmental responsibility. Preliminary analysis showed that grade IV IPAS worksheets still focused on routine exercises, terminology recognition, and teacher-centered activities, with limited investigation, field observation, and local wisdom integration. This gap makes local wisdom-based worksheets necessary because they connect environmental change concepts with students’ cultural and daily experiences. This study aimed to develop and examine the validity, practicality, and effectiveness of local wisdom-based IPAS worksheets for improving students’ understanding of the nature of science and environmental awareness. The study used a Research and Development design with the 4D model: define, design, develop, and disseminate. The main field trial involved 29 fourth-grade students at SD Xaverius 3 Bandar Lampung. Data were collected using expert validation sheets, teacher and student practicality questionnaires, pretest-posttest tests, and instruments measuring Nature of Science understanding and environmental awareness. The worksheet was highly valid, with an average expert validation score of 97.22%. Practicality reached 96.0% from teachers and 90.8% from students. The overall pretest mean increased from 47.8 to a posttest mean of 85.0, with a mean N-Gain of 0.71 in the high category. The N-Gain reached 76.7% for Nature of Science and 81.5% for environmental awareness. Right-tailed t-tests showed significant results for Nature of Science (t = 6.116, p = 0.000) and environmental awareness (t = 8.938, p = 0.000). The worksheet is valid, practical, and effective for supporting contextual IPAS learning and strengthening scientific literacy and environmental responsibility in elementary schools.

Abstract

This study examines the effect of agency conflict on risk-taking behavior in the Indonesian banking industry and evaluates the role of the Risk Committee as an internal governance mechanism. Three structural attributes of the Risk Committee—independence, expertise, and meeting frequency—are assessed as moderating variables that may strengthen internal oversight over managerial decision-making. Using panel data from conventional banks in Indonesia for the 2017–2023 period, the results show that agency conflict positively and significantly increases risk-taking behavior, indicating potential managerial opportunism arising from misaligned principal–agent interests. Among the moderating variables, Risk Committee expertise proves the most effective in weakening the influence of agency conflict, while meeting frequency also demonstrates a significant moderating effect. Conversely, committee independence does not exhibit a statistically significant moderating role. Overall, the findings underscore the importance of substantive governance quality—particularly professional competence and supervisory intensity—in mitigating the adverse effects of agency conflicts. These insights offer relevant implications for regulators and stakeholders.
