Abstract

This study aims to test or examine the effect of the use of virtual laboratories using the Guided Discovery Learning model on students' conceptual understanding abilities in static electricity material. This type of research is a quasi-experimental study with a nonequivalent control group research design. The population in this study were all students of class XII of SMAN 1 Monta. The sampling technique used in this study was purposive sampling with class XII MIPA 2 consisting of 28 students as the experimental class and class XII MIPA 1 consisting of 28 students as the control class. Before and after the treatment, both classes were given a conceptual understanding ability test in the form of essay questions that had previously been tested for their feasibility with validity, reliability, difficulty level of questions, and discriminatory power. The results of the initial test (Pretest) and final test (Posttest) of conceptual understanding ability were analyzed for homogeneity and normality to conduct a hypothesis test. The analysis of the hypothesis test using the t-test obtained a t_count of 3.49 and a t_table of 2.00. Thus, the calculated t_value is greater than the t_table, so H_0 is rejected and H_a is accepted, so it can be concluded that there is an influence of the use of virtual laboratories using the Guided Discovery Learning model on students' conceptual understanding abilities in static electricity material.

Abstract

Field practicum skills are a cornerstone of the professional competence of prospective biology teachers, yet their long-term developmental dynamics remain underexplored. This study aims to map the profile of field practicum abilities among Biology Education students at the Mataram University over a five-year period (2020-2024). Using a longitudinal quantitative approach, data were collected from 120 students through a structured, expert-validated questionnaire and analyzed using descriptive statistics and the non-parametric Kruskal-Wallis and Dunn's tests. The results indicate significant fluctuations in competency achievement: the highest average was in 2022 (79.28; SD=3.13) and the lowest in 2023 (65.93; SD=0.78). The Kruskal-Wallis test confirmed significant differences between years (χ² = 80.67; p < 0.05), with specific year pairs (e.g., 2022 vs. 2023) showing marked disparities. These findings reveal that field practicum ability is highly susceptible to curricular factors, institutional policies, and external disruptions such as extreme weather. The implication is that the development of prospective science teachers requires a learning ecosystem that is adaptive, evidence-based, and capable of proactively responding to environmental uncertainty.

Abstract

Science Process Skills (SPS) is an essential foundation in physics learning that requires the identification of students' initial profiles to ensure the development of appropriate teaching materials. However, this identification is often overlooked. Furthermore, the integration of the local environmental context and the STEM (Science, Technology, Engineering, and Mathematics) approach has the potential to be a relevant framework for improving scientific skills and environmental awareness. This study aims to identify students' SPS profiles as an empirical basis for developing an ecotourism-STEM-based physics e-module. The method used is a quantitative descriptive study with a survey technique. The research subjects consisted of 176 10th-grade students from SMAN 2 Mataram City and 38 students from SMAN 10 Mataram City who were selected purposively based on access to local ecotourism potential. The SPS test instrument was developed based on six main indicators, namely observation, classification, interpretation, prediction, experimental planning, and communication. Data were analyzed descriptively to map students' SPS profiles. The identification results show that students' SPS profiles are in the medium to low category with significant variability. The average SPS score at SMAN 2 Mataram City reached 38.52 (medium category) with a range of 3–68, while at SMAN 10 Mataram City the average score was 25.00 (low category) with a range of 3–75. The dimensions of experimental planning and data interpretation were the aspects with the lowest achievements, indicating that physics learning is still verification and procedural. This study concludes that identifying the SPS profile is a crucial stage in developing teaching materials that are adaptive to student needs. These findings form the basis for the development of an ecotourism-STEM integrated physics e-module designed to develop science process skills in a targeted manner while instilling environmental awareness through a contextual local context.
