Abstract

Practicum is a process to gain meaningful learning experience through hands-on and hands-on activities. Factors that cause constraints in biology practicum include incomplete tools, unavailable materials, and unavailability of practicum guides. The practicum guides circulating in schools also have various problems. Therefore, it is necessary to reconstruct the practicum guide and the existence of tools and materials that can be an alternative or solution that can overcome problems in the practicum of catalase enzyme. This research uses a qualitative descriptive method with the ANCORB flow (Analysis-Test-Reconstruction-Test). The samples used were five pieces of catalase enzyme practicum guides (LKS) from various sources with sampling techniques in purposive sampling. The analysis showed that the average LKS of catalase enzyme had a fairly good score but still needed LKS reconstruction that could measure the work of catalase enzyme quantitatively accompanied by alternative tools and materials in catalase enzyme practicum. The alternative tools that can be used are tools assembled using a syringe and a three-way stopcock. At the same time, alternative materials that can be used are water with acidic and alkaline pH, lime, lime water and clothes bleach as a substitute for hydrogen peroxide

Abstract

This study identifies the values embedded in the local wisdom of the Jolotundo Temple’s Ruwat Petirtaan tradition and integrates them into biology learning within the Merdeka curriculum. A descriptive qualitative method was employed, using interviews and observations, and analyzed through triangulation and inductive approaches with an emphasis on meaning over generalization. Findings indicate that the tradition embodies gratitude for the abundance of water and natural resources across the preparation, implementation, and closing stages. It functions as a form of environmental conservation. This local wisdom can be integrated into Phase E Biology content, particularly biodiversity and conservation, ecosystems, and environmental change. The results serve as a reference for developing teaching materials, modules, student worksheets, project assignments, and assessment items, while also encouraging the incorporating of local wisdom into policies, conservation programs, and educational practices that are contextual, participatory, and sustainable. The implication is that cross-stakeholder commitment through school–community collaboration and continuous evaluation is required to ensure tangible impacts on learning, environmental stewardship, and the strengthening of cultural identity.

Abstract

Understanding students’ mental models is essential to identify conceptual and representational challenges in learning intricate biological processes such as photosynthesis. This study explores senior high school students’ mental models of photosynthesis using a five-tier open-ended diagnostic test that integrates conceptual and visual understanding. A qualitative case study was conducted with 27 students in Bandung, Indonesia. The results revealed that only 22.8% of students demonstrated scientific understanding of the light reaction, and just 16.0% did so for the dark reaction. The majority of students exhibited initial or synthetic models, indicating fragmented knowledge, misconceptions, and difficulties in depicting key photosynthesis processes. Visualization results further highlighted students’ limited ability to construct accurate scientific representations, especially for the dark reaction. These findings suggest a need for model-based teaching strategies, multimodal representations, and formative assessments to enhance students’ conceptual and visual understanding of photosynthesis.
