Development of Biology Laboratory Equipment Work Instructions Using QR Codes as a Learning Resource for Biology Education Students

2026-01-22T22:20:01+00:00

This study aims to develop an E-atlas of laboratory equipment operation instructions, utilizing QR codes as a learning resource for biology education students. The objective is to enhance students' understanding of laboratory procedures through a mobile learning medium that integrates images, descriptions, and videos. The product was developed using the 4D model and tested for both validity and practicality. Data were collected through observations, interviews, and questionnaires involving experts, lecturers, and students. The analysis covered problem identification, student needs, curriculum alignment, and lecturer requirements. The product was designed using Canva Pro and Flip PDF Professional, ensuring compatibility with both computer and smartphone platforms. The validation results indicated very high validity, with 100% from material and media experts, and 92.5% from language experts. Practicality trials with biology education students yielded a score of 88.78%, while lecturer assessments showed a score of 96.42%. These findings demonstrate that the QR code-based electronic atlas is a valid, practical, and effective learning resource for biology laboratory activities.

Development of Interactive Website-Based Learning Media with the Assistance of Educandy on the Periodic Table of Elements Material

2026-03-16T05:29:21+00:00

ABSTRACT

Learning the periodic table of elements is often perceived as difficult because it involves abstract concepts, symbolic representations, and multiple relationships among elements that students must understand. This study aimed to develop interactive web-based learning media for periodic table material by integrating the Carrd platform with Educandy and to examine its validity and feasibility at the development stage. The study employed a Research and Development approach using the ADDIE model up to the development phase. The product was validated by five expert validators consisting of lecturers and chemistry teachers, and its feasibility was tested with 15 tenth-grade students at SMAN 1 Banjaran. The validation results showed an average score of 0.85, which was categorized as very high. Across aspects, the scores included software engineering (0.864), visual communication (0.872), functionality (0.810), learning achievement (0.883), media quality and relevance (0.790), interactivity (1.000), ease of understanding (0.830), learning guidance (0.830), and concept and theory accuracy (0.776). The feasibility test produced an average percentage of 89.13%, indicating that the media was feasible for limited use. Qualitative feedback from validators suggested improving the interface, adding supporting images, and refining several presentation elements. These findings indicate that the developed Carrd–Educandy-based learning media is valid and feasible as a learning support medium for periodic table material at the development stage.

Development and Feasibility of BIOSTACKO, a Game-Based Biology Learning Media Integrating Religious Values for Biodiversity in Senior High School

2026-03-16T05:23:16+00:00

This study aimed to develop BIOSTACKO, a game-based biology learning media integrating religious values for biodiversity material in senior high school, and to determine its feasibility and practicality. The study employed a Research and Development (R&D) approach using the 4D model, which includes define, design, develop, and limited disseminate stages. The product was validated by a material expert, a media expert, and a religious expert, and its practicality was assessed through responses from one biology teacher and students in a limited classroom trial. The validation results showed that BIOSTACKO obtained scores of 97% from the material expert, 88% from the media expert, and 95% from the religious expert, indicating that the product was highly feasible. The practicality test showed scores of 98% from the teacher and 92% from students, indicating that the media was highly practical for classroom use. These findings suggest that BIOSTACKO is a feasible and practical alternative learning media for biodiversity material that may support student engagement, conceptual understanding, and the integration of religious values in biology learning.

Validity and Feasibility of Interactive Multimedia on Sublimation Topics Oriented toward Chemical Literacy

2026-04-06T17:10:06+00:00

ABSTRACT

Sublimation is one of the chemistry topics that is often perceived as difficult because it is commonly taught as an abstract concept and is not sufficiently connected to real-life technological applications. This study aimed to develop interactive multimedia on sublimation topics oriented toward chemical literacy and to examine its validity and initial feasibility. The study employed a Design-Based Research approach using the ADDIE model and was limited to the analysis, design, and development stages. The product was developed using Articulate Storyline 3 and was designed to integrate four aspects of chemical literacy: chemical concepts, chemical contexts, chemical processes, and scientific attitudes. Data were collected through validation and feasibility questionnaires. Validation was conducted by material and media expert lecturers, while the limited feasibility test involved 15 Chemistry Education students who had completed the Organic Chemistry I course. The validation results showed that the developed multimedia was valid, with an average r-count value of 0.81 across the learning, chemical literacy-oriented material substance, and display and software aspects. The limited feasibility test showed an average percentage of 91%, indicating that the multimedia was highly feasible for initial use in learning. These findings suggest that the developed interactive multimedia has adequate validity and initial feasibility as a learning medium for sublimation topics oriented toward chemical literacy. Further studies are needed to examine its effectiveness in improving learning outcomes and chemical literacy skills.

The Effectiveness of Using STEM (Science, Technology, Engineering, Mathematics) Approach-Based LKPD on the Science Process Skills of Grade X Students in Bacteria Material

2026-04-06T17:08:08+00:00

The teaching materials on bacteria presented at the senior high school level are still abstract and require scientific activities, but there are not many student worksheets that guide students in developing scientific process skills as one of the 21st century skills. This study aims to determine the effectiveness of using STEM (Science, Technology, Engineering, Mathematics) approach-based worksheets in improving the scientific process skills of grade X students on the subject of bacteria. The research was conducted at SMAN 26 Bandung using a quantitative method with a non-equivalent control group quasi-experimental design. Data were collected through pre-tests and post-tests and analysed using normality tests, homogeneity tests, N-Gain tests, and independent sample t-tests. The results showed that the N-Gain score for the experimental class was 0.6041 (moderate category), higher than that of the control class, which was 0.0435 (low category). The average post-test score of the experimental class (79.52) was also higher than that of the control class (76.26). The conclusion of the study shows that STEM-based worksheets are very suitable as a learning medium and have a significant effect on improving students' science process skills in the subject of bacteria.
