Abstract

A high-quality assessment instrument is one that provides data that reflects actual conditions, is consistent and reliable, demonstrates varying levels of difficulty, and has a good discrimination index. Therefore, this study aims to test the validity, reliability, difficulty level, and analytical power of the items used to assess students' critical thinking skills. This study is descriptive and evaluative. The subjects were 31 11th-grade students at SMA Negeri 2 Painan. The data collection method used was a test. The study results indicated that for Grade XI, 17 test items were deemed valid, whereas 1 item was invalid. The reliability coefficient for Grade XI was 0.877, demonstrating that the test instrument is reliable. Regarding difficulty level, all 18 items were classified as difficult. In terms of discrimination power, 5 items fell into the poor category, while 13 items were categorized as fair. Based on the analysis of physics test items on the topic of fluids for the 2024/2025 academic year at SMA Negeri 2 Painan, it was concluded that the 11th-grade test items were valid and reliable. This indicates that the test items can be used as an evaluation tool.

Abstract

The objective of this community service activity is to equip productive-age women with the necessary skills to package food, obtain PIRT (household food industry) licenses, develop product branding, and market traditional food by utilizing social media, websites, and e-commerce platforms integrated with online tour packages. This initiative indirectly contributes to improving the economic welfare of women in Batu Bulek and preserving the region’s traditional food. The skill development program for productive-age women groups in Nagari Batu Bulek in marketing traditional food integrated with online tourism packages was carried out through several stages, namely the preliminary stage, preparation, and implementation. The results showed an increase in participants’ understanding with an N-gain score of 0.36, which falls into the medium category. This activity also received positive responses from the participants, as indicated by the satisfaction survey with an average score of 93.7. Through this training program, productive-age women in Nagari Batu Bulek gained knowledge and skills in food packaging and product branding.

Abstract

Education for Sustainable Development (ESD) aims to develop competencies that empower individuals to reflect on their own actions while considering their social, cultural, economic, and environmental impacts, both present and future, from local and global perspectives. The integration of ESD concepts into assessment instruments has become an urgent necessity to foster learners’ critical awareness of sustainability issues. Authentic assessment is often positioned as a magical solution in education, implemented to address various complex problems. This activity aims to Building Teacher Capacity in Designing Digital Authentic Assessments Oriented toward Education for Sustainable Development (ESD). This community service activity in the form of mentoring uses a method that consists of several stages. The first stage is the preparation stage, the second stage is the guided and independent activity stage, and the third stage is monitoring. This activity received a positive response from the participants, namely the teachers of MAN 2 Bukittinggi, with more than half of the participants stating that the training was interesting, beneficial, and effective.

Abstract

Higher education is expected to equip students with Higher Order Thinking Skills (HOTS); however, assessment practices in physics laboratory learning still often emphasize procedural performance. This study aims to analyze assessment needs and to develop and conduct content validation of a HOTS-oriented performance assessment for physics laboratory learning in higher education to support Sustainable Development Goal 4 (Quality Education). This study employed a research and development (R&D) approach using the ADDIE model, limited to the Analyze, Design, and Develop stages. The participants were 49 undergraduate physics students selected using purposive sampling and laboratory assistants involved in practicum activities. Data were collected through essay tests, practicum module analysis, interviews, and observations, and analyzed using descriptive quantitative and qualitative methods. Content validity was evaluated through expert judgment using Aiken’s V index. The results showed that existing assessments had not optimally measured HOTS, particularly evaluating (C5) and creating (C6). Therefore, a HOTS-oriented performance assessment integrating C4, C5, and C6 was developed, consisting of performance tasks, scoring rubrics, observation sheets, and self- and peer-assessment instruments. The content validation results indicated high validity with an Aiken’s V value of 0.89. These findings provide a validated conceptual foundation for further implementation and evaluation to support SDG 4 in higher education.
