Abstract

This study aims to investigate the impact of the STEM–Problem–Based Learning (PBL) model, combined with the OLabs virtual laboratory, on the computational thinking skills of eighth-grade students in science education. The research used a quasi-experimental pretest–posttest control group design with a population of all eighth-grade students at SMP Negeri 1 Sukoharjo in the 2024/2025 academic year. Cluster random sampling was applied, resulting in class VIII C as the experimental class and VIII B as the control class. Data were collected using a computational thinking skills test, and hypothesis testing was conducted through the Independent Sample T-Test at a 0.05 significance level. The results showed a significant effect of the STEM–PBL model, as indicated by a significance value of 0.001 < 0.05 and a higher score improvement in the experimental class. These findings confirm that integrating STEM–PBL with the OLabs virtual laboratory effectively improves students’ computational thinking skills. This study implies the importance of implementing STEM-based problem-solving and virtual experimentation to enhance students’ computational thinking in science learning.

Abstract

Background: The integration of biomechanics with digital motion-analysis technologies has introduced new approaches for examining movement efficiency, kinematic characteristics, and technical patterns in walking and running activities. Kinovea, as an accessible motion-analysis software, provides both visual and quantitative feedback. However, its application in supporting technique development among beginner athletes remains insufficiently explored. Aim: This study aims to describe the use of Kinovea in biomechanics training and examine its contribution to the awareness of kinematic characteristics and movement techniques among beginner athletes. Methods: A descriptive qualitative design involved 72 beginner athletes aged 18–25 years selected through purposive sampling. Data were collected over 16 weeks through interviews, field observations, and motion video recordings analyzed using Kinovea. Kinematic data focused on joint angles, stride behavior, and movement phases during walking, running, and the flight phase. Qualitative data were analyzed using content analysis with NVivo 12, while kinematic results were interpreted descriptively to identify performance patterns and areas for technical refinement. Result: Kinematic analysis showed coordinated joint-angle patterns across all phases. Walking analysis identified arm swing angles of 50.9°–58.8° and leg separation angles of 64.3°–67.2°, indicating a stable gait rhythm. The running analysis revealed knee angles of 68.8°–69.8° and elbow angles of 87.6°–89.1°, indicating efficient propulsive mechanics. The flight phase demonstrated knee angles of 81.2°–87.8° and elbow angles of 80.4°–88.3°, suggesting effective momentum use and postural stability. These measurements supported stride-efficiency assessment and technique evaluation. Qualitative findings revealed that Kinovea enabled athletes to interpret movement phases and identify technical inefficiencies through slow-motion and frame-by-frame visualization. Conclusion: Kinovea supports basic motion analysis by providing clear kinematic information and helping beginner athletes observe and refine their movement techniques. The findings also offer practical value for coaches by enabling more precise identification of inefficient patterns and guiding targeted corrections during early-stage training.

Abstract

Background: Environmental damage in Indonesia is worsening, as shown by the low Environmental Performance Index and limited public awareness, which reflect low student environmental literacy. The Culturally Responsive Transformative Teaching (CRTT) model provides a contextual approach by integrating cultural values to enhance knowledge, attitudes, and pro-environmental behaviors.Aims and scope of paper: This study aims to determine the effect of the Culturally Responsive Transformative Teaching (CRTT) model on science learning on the environmental literacy of 7th grade students.Methods: This study used a quasi-experimental method with a pretest-posttest control group design. The sampling technique was selected using cluster random sampling. The research instrument was the MSELS instrument adapted from Mc.Beth and Volk (2009) in the form of multiple-choice tests and questionnaires tailored to the 7th grade science material on ecology and biodiversity. The research sample used class 7 H as the control class with a discovery learning model consisting of 32 students and class 7I as the experimental class with a CRTT model consisting of 31 students.Result: The results showed that the CRTT model in science learning had an effect on the environmental literacy of 7th grade students with a significance value of 0.000 (0.000< 0.05).Conclusion: The study concludes that the CRTT model effectively enhances students’ environmental literacy in science learning, highlighting the need for cultural integration and further research across diverse contexts.

Abstract

Indigenous-based Experiential Learning (IbEL) model has been developed to promote pre-service science teachers' creative thinking skills. This model emphasizes a more holistic, community-based education grounded in Indigenous knowledge and cultural practices. This study aims to evaluate the effectiveness of the IbEL model in enhancing the pre-service science teachers' creative thinking skills. The study involved 29 participants who were randomly selected from a larger population. The participants were assessed using a pretest and posttest design to determine the changes in their creative thinking skills after being taught using the IbEL model. The study utilized a standardized evaluation instrument to measure creative thinking skills, including Fluency, Flexibility, Originality, Elaboration, Risk-Taking, Complexity, Curiosity, and Imagination. The data analysis method used was Rasch analysis with stacking and racking techniques. Using pretest and posttest evaluations, the researchers found a significant increase in creative thinking skills, with the Observation course showing a higher increase. The study highlights the importance of creativity in teaching and learning and how enhancing creative thinking skills can improve student achievement. The IbEL model encourages students to appreciate local knowledge and experience, context, and situation in learning, and direct experience, leading to more culturally sensitive research outcomes. The study contributes to the development of better learning models to enhance pre-service science teachers' creative thinking skills.
