Abstract

Think Pair Square Style Cooperative Education encourages each student to become a proficient and independent learner. Given that this learning emphasizes 21st-century skills such as critical thinking, creativity, and teamwork. It was such as necessary to assess how effectively the application of this method enhances students' critical thinking abilities in the real world. The objective of this project is to improve student cooperation in cell biology classes by implementing a cooperative learning model similar to the Think Pair Square. The Classroom action research model was developed by Kemmis and McTaggar, which served as the framework for the procedure employed in this study. The outlines of the four stages of classroom action research are technique—planning, implementation, observation, and reflection. This instructional approach is seen to be beneficial as it enables students to share their thoughts and helps them see alternative problem-solving approaches. Students can seek explanations from other students to explain how to solve the problem if they are struggling with that. From the Data results, there were rising scores in the form of scoring that serve as evidence for this. Students' collaboration skills scored an average of 1.6 (level 1, or basic level) in the pre-cycle, 2 (level 2, or medium level), and 3.56 (level 3, or trained level) in cycle 2. Think Pair Square's implementation at SMA in Bandung could improve collaboration both within and outside of the classroom, foster more active dialogue and idea exchange, and promote student contact.

Abstract

Mathematical problem-solving ability is a fundamental competency in secondary mathematics education; however, many students continue to face significant challenges in mastering this skill. In response, various instructional strategies have been implemented, among which Problem-Based Learning (PBL) has received considerable attention. This study aims to systematically and quantitatively examine the effect of PBL on junior high school students’ mathematical problem-solving abilities through a meta-analytic approach. A total of 24 empirical studies published between 2013 and 2024 were rigorously selected based on predefined inclusion criteria. The meta-analysis results indicate that PBL has a large and statistically significant impact on improving students’ problem-solving skills, with a mean effect size of 0.89, which falls within the high category. Furthermore, the effectiveness of PBL was found to vary across moderator variables, including implementation duration, assessment instrument type, and grade level. These findings suggest that PBL is an effective instructional strategy for enhancing students' critical thinking and problem-solving capabilities. The study recommends broader and more systematic implementation of PBL in schools, as well as targeted teacher training to support its optimal integration into classroom practice.

Abstract

This article presents a conceptual review examining the potential of Sacha Inchi–based plant milk as an innovation in contextual learning to support scientific literacy and nutritional awareness. Drawing on pedagogical and educational technology perspectives, the review synthesizes literature on contextual learning, learning resources, scientific literacy, nutrition education, and food-based innovations. Scientific literacy is positioned as a conceptual construct that develops through learners’ engagement with meaningful real-life contexts rather than as a measurable instructional outcome. The synthesis highlights a pedagogical shift from content-centred learning to context-centred learning, in which every day phenomena function as learning resources that mediate conceptual understanding. Within this framework, Sacha Inchi–based plant milk is conceptualized as an authentic and interdisciplinary learning resource connecting science, nutrition, and sustainability. The review emphasizes the role of educational technology in organizing and integrating contextual learning resources through purposeful pedagogical design. Rather than evaluating instructional effectiveness, this article offers a theoretical framework to inform instructional design, curriculum development, and future research in contextual and technology-supported education.

Abstract

River water quality modeling needs appropriate and suitable coefficients especially in application for specific river like urban river. Aim: This study aims to determine the value of the coefficient with a short term duration and a variable test time span.  Several ways and methods of determining the rate of deoxygenation are developed according to the characteristics of the river and the environment. Modification method was applied in this research in which the test time span was unequal. The river chosen in this study is the Citepus River, Bandung, Indonesia representing an urban river in a tropical country. Methodology and Results: Sampling was carried out in the dry season. The laboratory analysis method used in determining the rate of deoxygenation uses the Slope Method of data from the short term incubation, which is ten days. The results showed that the Thomas Slope method's deoxygenation rate (K1) was 0.095 per day in the upstream segment, 0.917 per day in the middle segment, and 0.180 per day in the downstream segment. While the Ultimate BOD (La) value is 46.95 mg/l in the upstream segment, 38.70 mg/l in the middle segment, and 37.60 mg/l in the downstream segment. Conclusion, significance, and impact of study: The results of this study show that the value of the deoxygenation rate is similar to the theoretical surface water conditions. However, in the upstream segment, there is still a low deoxygenation rate value due to non-optimal activity of microorganisms. This findings will be very useful both in water quality modeling and river management.

Abstract

Nori is a seaweed-based food that is favored by the Indonesian people, but its availability is still limited. Meanwhile, the abundant production of land kale (Ipomoea reptans) as a local vegetable has not been optimally utilized, resulting in low economic value and its potential as a food source has not been maximized. One solution to overcome this problem is to use organic land kale as an alternative ingredient for making nori. Organic land kale is known to have good nutritional content and is commonly consumed by the community. This study aims to determine the level of acceptance of analog nori made from organic land kale as a healthy snack through organoleptic tests. The method used was an experiment with a completely randomized design (CRD), consisting of 24 samples, 6 treatments, and 4 repetitions. The treatment given was carrageenan concentration (0%, 0.6%, 0.8%, 1%, 1.2%, and 1.4%) Data were analyzed using the Friedman Test to assess panelists' preferences for taste, color, aroma, and texture parameters. It can be concluded that the results show the addition of carrageenan at 1% produces analog nori with the highest level of acceptance, so it is considered the most optimal formulation.
