Abstract

The engaging and personalized nature from short video makes it quickly popular, yet concerns persist about their potential to diminish critical thinking skills. This study investigates whether short videos with educational content can improve students' critical thinking skills. Using a quasi-experiment method, Thirty-three participants were divided into control and experimental groups, with critical thinking measured using the Holistic Critical Thinking Scoring Rubric (HCTSR) based on essay analysis in pretest and posttest. After administering educational short videos to the experimental group, the results showed that there was an increase in students' critical thinking skills, shown by the result of controlling the pretest variable through the ANCOVA test with a p-value of <0.001. The result highlights the potential of educational short videos as tools for fostering critical thinking by providing interventions which prioritize treatment fidelity through standardized protocols (SOPs) for content delivery, validating assessment tools, and structuring content design. Recommendations for future research include larger sample sizes, repeated data collection at strategic intervals, and rigorous validation of question complexity.

Abstract

The implementation of monotonous learning that lacks active student participation can contribute to the low critical thinking skills of students. This research aims to enhance students' critical thinking skills through the application of project-based learning (PjBL). The study evaluates the extent to which students' critical thinking skills can be improved through the implementation of PjBL. The research employs a Quasi-Experimental method. The study subjects consist of two groups: the experimental group, which utilizes the PjBL, and the control group, which follows a conventional model. Overall, after conducting prerequisite tests and hypothesis testing, a significant difference in critical thinking scores is observed between the experimental and control groups. Students are provided with the opportunity to exercise their critical thinking skills during the execution of project tasks. Consequently, it can be concluded that the PjBL model positively impacts the essential thinking abilities of 11th-grade machanical engineering students in creative products and entrepreneurship subject.

Abstract

This study aims to evaluate the performance of vertical-axis wind turbines (VAWTs) with three different configurations, including Savonius, Darrieus, and a Savonius-Darrieus hybrid wind turbine, using Computational Fluid Dynamics (CFD) simulations. The methodology involves 3D geometry modeling, simulation parameter setup, meshing, and post-simulation analysis using SolidWorks 2022 software. The simulation results indicate that the Savonius turbine achieves the highest power coefficient (Cp) and torque coefficient (Ct) among the three designs, with a maximum Cp value of 0.5 at a Tip-Speed Ratio (TSR) of 0.4. Conversely, the hybrid turbine demonstrates lower efficiency, although it theoretically offers potential for improving performance at low wind speeds. Pressure and flow velocity distributions reveal that the Savonius turbine maintains the most stable pressure pattern compared to the other configurations. These findings highlight the potential of the Savonius turbine as a small-scale renewable energy solution, particularly in urban areas with low wind speeds. Further research is recommended to optimize hybrid turbine designs using machine learning approaches and empirical validation through field experiments to support the achievement of Sustainable Development Goals (SDGs), particularly Goal 7, affordable and clean energy.
