Abstract

Vectors in kinematics are rarely highlighted in high school. Even though vectors are the language used by physicists. This study aims to determine the validity and reliability of the test instrument developed and to explore the ability of vectors in kinematics of high school students. The method used in this research is research and development of the 4D model. The developed test instrument for vectors in kinematics is in the form of multiple choice with an arrow direction accompanied by a command to describe the vector and explain the reason for choosing the vector direction. The test instrument covers one- and two-dimensional kinematics topics by highlighting the concepts of velocity and acceleration. Two-dimensional kinematics is divided into constant velocity and increasing velocity. This test instrument consists of thirteen questions with an average point-biserial coefficient of 0.493 and KR-20 of 0.784. Then, this test instrument was used to measure the vector ability in kinematics of high school students with a sample size of sixty-seven students. It was found that most high school students had difficulty in acceleration as two-dimensional vector, acceleration as one-dimensional vector, and velocity as one-dimensional vector with few obstacles. Learning with the method of integrating vectors in kinematics has the possibility to solve this problem.

Abstract

The importance of developing critical thinking skills (CTS) is claimed as a major education purpose.  Recently, enhanced learning has been conducted to promote students' CTS through study on certain topics (specific domains). Based on the numerous studies on CTS, there is a need for an assessment instrument to test students' CTS.  This research aims to develop an instrument of CTC on mechanical wave topics for senior high school students. The instrument consists of seven essay items and one forced-choice item, tested to 45 students of class XI high school in Malang. The validity test obtained an excellent Cronbach alpha coefficient of ? = 0.717. There was also an inter-rater test for the scoring guideline reliability using the intraclass correlation coefficient (ICC) with high reliability results (? = 0.909). The results of this study indicate that the instrument is qualified to be used to measure students' CTS on mechanical wave topics.

Abstract

This research explores the influence of using open-ended worksheets in interactive demonstration learning on students' understanding of harmonic motion and scientific reasoning. It is a quasi-experimental study with a pretest-posttest control group design. Data were obtained from conceptual understanding and scientific reasoning tests and analyzed using parametric and non-parametric tests. The results show that open-ended worksheets enhance students' concept comprehension and scientific reasoning. There was a significant difference in conceptual understanding between the two classes. However, there was no difference in scientific reasoning. These findings hold valuable implications for improving learning with open-ended worksheets and interactive demonstration models.

Abstract

This study investigated the effectiveness of integrating the 9E Learning Cycle Model with STEM approaches to enhance students' Science Process Skills (SPS) in static fluid concepts. The research employed a mixed-methods embedded experimental design with 32 senior high school students. Quantitative data were collected through pre- and post-tests, while qualitative data were gathered via observations and interviews. Results showed significant improvements across all SPS components, with N-gain values ranging from 0.63 to 0.64, indicating medium gains. Students demonstrated enhanced abilities in observing, classifying, measuring, inferring, predicting, and communicating scientific concepts. The integrated approach facilitated practical application of knowledge, as evidenced by students' work on flood-resistant garage prototypes and wave-powered electricity generators. Qualitative findings revealed increased student engagement and improved problem-solving skills. The study concludes that the integration of the 9E Learning Cycle Model with STEM approaches offers an effective framework for enhancing students' science process skills and their ability to apply these skills to real-world problems. These recommendations aim to provide a more comprehensive understanding of the approach's potential in science education across various domains and student populations

Abstract

Future challenges for learning require students to not only master concepts, but also develop thinking skills, one of which is problem solving skills. The aim of this study was to identify the effect of Experiential Learning with STEM-Computational thinking (STEM-CT) approach on students' problem solving skills. This research falls under a quasy experiment type with pretest-posttest control group design involving  60 students in 11th grade, especially on static fluid topic. The author collected quantitative data through pre-test and post-test, to assess the difference in students' problem solving skills between the experimental and control groups. Data analysis was carried out using parametric statistics, namely independent sample t-test, and obtained sig. 2 tailed of 0.001 which meets p < 0.05, so it can be concluded that there are differences in problem solving skills between the control class and the experimental class, after being given different treatments. The average N-Gain scores of the experimental class is also higher than control class. It indicates the effect of experiential learning with STEM-CT approach on students' problem solving skills. In the future, more in-depth research is needed related to the effect of experiential learning on various other thinking skills, especially in physics learning.

Abstract

This study aims to explore students' scientific explanation skills through the implementation of the Problem-Based Learning (PBL) model assisted by PhET simulations on the topic of dynamic fluids among high school students. The research employed a mixed-method approach with an explanatory model involving 58 eleventh-grade students. Data were collected through tests and interviews. Quantitative data were analyzed using a paired sample t-test, N-gain calculation, and effect size, while qualitative data were analyzed through data collection, reduction, coding, and drawing conclusions.The analysis results showed that the scientific explanation skills of students in the experimental class increased significantly compared to the control class. The paired sample t-test results indicated a significant difference between the experimental and control classes, and the N-gain score of 0.4096 indicated a moderate improvement. More students in the experimental class were categorized as fully supported, while the control class was dominated by students in the invalid category. The implementation of PBL assisted by PhET simulations proved effective in enhancing students' abilities to construct claims, provide evidence, and present logical scientific reasoning. In this study, the integration of PBL and interactive technology in science learning is suggested as a means to improve students' scientific explanation skills.
