Abstract

This research uses the research and development (R&D) method with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The e-booklet product developed has special characteristics because it integrates a project-based learning approach with ESD values, thereby encouraging students to think critically and creatively and to be aware of environmental and sustainability issues. The analysis stage includes needs analysis through surveys and interviews, curriculum analysis, and student characteristics analysis. Design stage with product prototyping. Three experts (1 material expert, 1 media expert, and 1 linguist) carry out the development stage by validating the product. The results of expert validation showed high eligibility rates: 94.5% for linguists, 90% for material experts, and 88% for design experts. Meanwhile, the results of the practicality test received scores of 91% from lecturers and 94.75% from students, both of which are in the very practical category. Thus, this project's ESD e-booklet can serve as a context-based learning resource that supports the implementation of sustainable development-oriented education (ESD) in higher education.

Abstract

This study aims to develop and evaluate the effectiveness of a project-based digital portfolio, BioPorta, as an assessment and learning medium in the Medicinal Plants course for biology students. The research employed a research and development (R&D) approach using the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. The product was validated by media and material experts, achieving high validity scores of 86.06% and 94%, respectively. Practical testing showed positive results, with scores of 90% from lecturers, 77.06% from small group trials, and 86.18% from field tests. The effectiveness test using N-gain analysis indicated a significant improvement in student learning outcomes, with a score of 0.805 in the experimental class compared to 0.225 in the control class. These findings demonstrate that BioPorta is a valid, practical, and effective tool for enhancing student competence, engagement, and learning outcomes through project-based digital learning.

Abstract

The ability to think critically is a key competency required of students in the 21st century, particularly in science education. This study aimed to develop and empirically evaluate a critical thinking skills assessment instrument for Grade 11 senior high school students in biology learning. The instrument was developed using the ADDIE development model, encompassing the analysis, design, development, implementation, and evaluation stages. Empirical testing was conducted during the implementation stage with Grade 11 senior high school students in Jambi City. Item analysis was performed to examine content validity, empirical validity, reliability, item difficulty, and discrimination indices. Empirical data were analyzed using ANATES version 4.0.9. The results indicated that 22 out of 56 items met the predefined validation criteria, demonstrating acceptable levels of item difficulty and discrimination power. The reliability coefficient of the finalized instrument was 0.68, which is considered acceptable for an exploratory educational assessment instrument. These findings suggest that the developed instrument possesses adequate psychometric properties for measuring students’ critical thinking skills in biology learning and can support future instructional evaluation and research within similar educational contexts.
