Abstract

This study aimed to enhance biology students’ critical thinking skills through the development of STEM-based instructional materials for the Invertebrate Zoology course. Employing a design and development research approach using the ADDIE model, the study involved needs analysis, module development, expert validation, practicality testing, and effectiveness evaluation. The materials integrated STEM elements including ecological measurement tools, technological media, specimen preparation, and data analysis. Validation by experts yielded a 98% score, indicating high validity. Practicality tests showed increasing student satisfaction across individual (83.47%), small group (85.66%), and full-class trials (94.30%). The effectiveness was assessed using a one-group pretest-posttest design. The Wilcoxon Signed-Rank test revealed a statistically significant improvement in students’ critical thinking skills (p = 0.000). Posttest results showed that 66.67% of students reached the “very good” category and 33.33% were in the “good” category, with a mean score of 84%. Among Ennis' critical thinking indicators, “defining terms” had the highest score (95.24%), while “generalizing from evidence” scored the lowest (72.38%). These findings indicate that STEM-integrated teaching materials can effectively foster students’ higher-order thinking in biology education.

Abstract

Gastropods are a group of mollusks that play a crucial role in maintaining the balance of aquatic and terrestrial ecosystems through decomposition and as components of the food chain. This study aimed to analyze the diversity, abundance, dominance, and similarity of gastropod communities in the Rajolelo Grand Forest Park, Central Bengkulu. The study was conducted from November 2025 to January 2026 using the Visual Encounter Survey (VES) method combined with transects in two habitat types: an artificial lake and secondary forest. The data obtained were analyzed using the Shannon-Wiener diversity index, Simpson dominance index, relative abundance, and community similarity index. The results showed nine gastropod species from several families distributed across both study habitats. The artificial lake habitat had a higher number of individuals with certain species dominating, while the secondary forest habitat showed a more even community composition. These differences in community structure are related to habitat conditions, food source availability, and environmental factors such as temperature, pH, and humidity. In general, both habitats exhibit distinct yet complementary gastropod community characteristics in maintaining ecosystem balance in the Rajolelo Grand Forest Park area.

Abstract

Biology is a field of study that systematically examines natural phenomena. Biology learning is not only about conveying information in the form of facts and concepts, but also requires students to be involved in the discovery process, which requires critical thinking skills. However, low learning motivation is still an obstacle in the learning process. Various factors, such as monotonous teaching methods, a lack of interactive learning media, and the presentation of uninteresting materials, can reduce students' interest in learning actively. This low motivation has a direct impact on low student learning outcomes. Based on these problems, this study aims to determine the effect of using interactive media E-LKPD integrated with Wordwall on the learning motivation of high school students. This study uses a quantitative approach with a quasi-experimental design method, involving two classes XI, namely the experimental class using E-LKPD Wordwall media and the control class using conventional methods. The research instruments used were learning motivation questionnaires and documentation of learning outcomes. Data were analysed using the t-test. The results of the analysis showed a significant difference between the two groups. The significance value (2-tailed) of 0.000 indicates that the use of E-LKPD integrated with Wordwall has a significant effect on increasing student learning motivation. Thus, this interactive media can be an effective alternative in biology learning at the high school level.
