Development and Validation of the Force Diagrams Representation Test
Full text linkExperts and students frequently use force diagrams as a physics representation to understand the force concept. This study aims to develop and validate a force diagram representation test that physics teachers in senior high schools can use. Research and development is implemented in this study by following some steps: analyze, define, design, implement, and evaluate. The 225 senior high school students in Pontianak are involved in this study, from the pilot study to the testing on a large scale. Data analysis includes measuring content validity, reliability index, and parameters of the test using the Rasch model. The test consists of 25 items in a multiple-choice format that cover three contexts: horizontal plane, inclined plane, and hanging object, and covers three situations, including the object being at rest, moving with constant velocity, and moving with constant acceleration. The results show that the content validity test obtained a score of 0.95 for the very good category, and the readability index results obtained a score of 7.42, which means it is easily understood by high school students. Rasch analysis shows that a unidimensional percentage is 30.5%, which means the test is able to measure one ability, and item reliability is 0.98. All items fit the Rasch model and had varying item difficulties. This study indicates that the force diagram representation test (FDRT) can be used by teachers as one of the instruments to measure students’ understanding of force

Newtonian Yoyo (Lato-Lato) Phenomenon in Indonesia: An Innovative Resource for IGCSE Physics Teaching and Learning?
Full text linkThis paper aims to stimulate a teaching and learning reflection for Indonesian IGCSE physics classrooms through a recent booming and recreational game of Newtonian yoyo called lato-lato. As physics is one of the critical and complex subjects in secondary school, it establishes a struggle for students to comprehend the concept of physics. The 21st-century physics education learning aims to promote high-end reasoning and deep understanding. Contextual physic learning will support this mission to reach maximum attainment for students. Physics through contextual knowledge will be more feasible for students. The recent phenomenon of lato-lato encounters a new interest for students. Lato-lato as a demonstrator and contextual example will be a resourceful material for several concepts of Newtonian mechanics, for instance: collision and energy. In addition, lato-lato may provide an advanced idea of circular motion, momentum, and impulse, oscillation. Lato-lato involvement may bring a chance for IGCSE curriculum adjustment in mechanics topics to become a significant pre-learning process. By using the adjusted curriculum, students are more likely to reach their maximum attainment and conceptual understanding of mechanics because students feel interested and encouraged to learn through a problem-solving and real-world setup. Lato-lato (Newtonian Yoyo) phenomenon may solve students’ learning difficulties in IGCSE physics through a conceptual phenomenon

The Characterization of Wave Parameters in Laboratory Scale of Wave Simulator Using Video Tracking Analysis
Full text linkUnderstanding the wave parameters in the ocean wave phenomenon is necessary to learn and develop the potential of ocean wave energy. Therefore, this study created a simple laboratory-scale of wave simulator that was developed using an electric motor. The various wave parameters obtained by different treatments were carried out using variations in the angle of the wedge inclination and the rotational speed of the wave generator. In this system, two pulleys of different sizes were used, a large pulley with a diameter of 20 cm and a small pulley with a diameter varying between 1.25 cm and 1.98 cm. Changing the size of the pulleys uses the principle of axial rotational motion to produce different rotational speeds. Moreover, the video tracker analysis application was used to characterize the parameters of the waves generated in the simulator that has been designed. The parameters obtained include wave height, amplitude, frequency, wave period, wavelength, and wave propagation speed. In the examination and analysis that have been carried out, it has been found that increasing wave height and amplitude correlates with increasing the inclination of wedges. The frequency and speed of the waves are linearly related to changes in the rotation speed of the wave generator. For the characteristic wavelength, there is inverse relation to the rotational speed. Based on this study, the wave simulator system and video tracking analysis application can be used to increase the understanding of wave parameters. In addition, this research can also be used as preliminary research on developing a prototype for an ocean wave energy converter on the laboratory scale
