Abstract

The lack of teaching materials use, especially in viscosity topics, has decreased students' knowledge and analytical skills in measurement. The research aimed to design a Student Worksheet (LKPD) for viscosity topics to assist and train students in measuring the viscosity of fluids. The fluids used in the experiment were biosolar, dexlite, and pertamina dex, considering that these fuels are among the most significant commodities and widely used in Indonesia. Additionally, the viscosity of diesel fuel is an important property affecting combustion and engine injection. This research employed a quantitative method using laboratory experiments to measure the viscosity values of biosolar, dexlite, and pertamina dex using the falling-ball method. The research findings were utilized to develop the LKPD teaching materials. The results showed that the viscosity values of biosolar fuel, dexlite, and pertamina dex were 3.651 cP; 3.579 cP; and 3.004 cP; respectively. These results differed slightly from the literature but were still deemed suitable for the LKPD teaching material design. The title of the LKPD teaching material used was "Viscosity of Biosolar Fuel, Dexlite, and Pertamina Dex Using the Falling-Ball Measurement Technique," and it followed the format of a cover, usage instructions, summary of the material, laboratory assignments, and questions.

Abstract

The Learning Management System in science education has become crucial in modern educational settings. However, there is a lack of comprehensive resources to guide the implementation of hedonic and pragmatic qualities in UX. This study aims to identify emotional design factors and adopt an innovative perspective with a rhetorical approach to enhance the user experience.  This study adopts the Design-Based Research methodology using the UEQ questionnaire with 26 items, involving a total population of 122 students. Conducting research through a User Experience Questionnaire, rhetorical evaluation, and open-ended questions in three control groups, the physics learning experience through Moodle at the Sarjanawiyata Tamansiswa University was evaluated, specifically in the Physics Education study program. The research findings demonstrate that improving UX leads to higher user satisfaction. According to the results of the UEQ analysis, it is evident that attractiveness, clarity, and efficiency are rated above average. Meanwhile, aspects of dependability, stimulation, and novelty are assessed below average criteria. The study concludes that ethos, pathos, and logos are essential in embracing the pragmatic and hedonic aspects of UX.

Abstract

High-order thinking skills (HOTS) are part of 21st-century abilities. However, students still need help solving problems, especially in simple harmonic motion material, which several studies have proved to be relatively low in HOTS. Students' HOTS abilities will be trained with various learning strategies, such as a combination of teaching materials and learning models using technology. This study aims to develop an E-ILAU (Independent Learning Activity Unit Electronic) using PjBL (Project Learning)-STEM (Science, Technology, Engineering, Mathematics) integrated with TPACK (Technological Pedagogical Content Knowledge) to improve the HOTS of high school students on simple harmonic motion topics. This research and development adapts the ADDIE design with the Analysis, Design, Development, Implementation, and Evaluation stages. Data collection instruments and data analysis techniques in this study included a product validation questionnaire to determine product validity, an E-ILAU readability test questionnaire to determine product legibility before being tested, a learning implementation observation sheet to determine product practicality, and a topic of higher order thinking skills in Simple Harmonic Motion topics to find out the effectiveness of the product obtained from the pretest-posttest in terms of the results of the difference test, n-gain, and effect size. E-ILAU was implemented using a one-group pretest-posttest design. The results showed that the validity of E-ILAU was a very valid category, the readability of E-ILAU was outstanding, and the practicality of E-ILAU in learning was carried out by the lesson plan, which received a positive response from students. As well as the effectiveness of E-ILAU in the practical category of increasing higher-order thinking skills. The results showed that the PjBL-STEM-based E-ILAU integrated with TPACK was classified as valid, practical, and effective for improving the high-level thinking skills of high school students in Simple Harmonic Motion topics.

Abstract

The study aims to show that an inquiry-based approach develops pre-service teachers' experimental competency. The static-group pretest-posttest design, an experimental quantitative analysis method, has been utilized. The experimental group comprised 36 pre-service physics teachers, with 11 participants in the control group. Assessment of experimental competency levels included the PLIC test and an experimental competency test. The experimental competency of pre-service teachers is evaluated through video recordings, observations, learning products, and surveys conducted via Microsoft Teams. Following each experiment, pre-service teachers assess their achievement levels based on behavioral indicators in a rubric table, utilizing a 3-level behavior scale for self and peer assessment. Parametric and nonparametric tests were chosen for evaluating the research data after confirming normal distribution using the Kolmogorov-Smirnov and Shapiro-Wilk tests (in the case of SPSS 20.0). The article’s main findings determined that an inquiry-based laboratory organizational procedure for each experiment in the General Physics Laboratory course to develop pre-service teachers' competency included two stages (stage 1 with six steps and stage 2 with four steps) under the pre-service teachers’ active self-discovery to perform learning tasks with three open levels of experiments. Within the scope of this article, we have given an illustrative example of applying this procedure for the experiment “Investigate the properties of collisions on an air track and verify the law of linear momentum conservation” in the General Physics Laboratory course for the second-year pre-service physics teachers. Furthermore, based on the test results along with survey findings and spider diagram analysis showed that this procedure developed relatively stable most of the behavioral indicators except for two behavioral indicators such as “Proposing ideas to improve experimental instruments” and “Proposed measures to reduce error” of pre-service physics teachers.

Abstract

Not all teachers have the ability to develop diagnostic instruments for misconception. Meanwhile, there is an urgent need to diagnose student misconceptions. Therefore, this research aims to carry out the process of adapting misconception-diagnostic instruments to wave and vibration materials. This study used a cross-sectional quantitative survey method. The adaptation process was conducted with 306 state high school students taking wave and vibration classes. Respondents were selected using convenience sampling techniques. 4WADI (Four-tier Wave and vibration Diagnostic Instrument) was translated into Indonesian, consulted with language experts, and assessed by material and evaluation experts to produce an instrument appropriate to the Indonesian cultural context. Before the empirical test was carried out, I-4WADI (Indonesian et al. and vibration Diagnostic Instrument) was tested for readability on 35 students. As a result, the I-4WADI has excellent readability. The validation results of six experts were analyzed using the Aiken V technique. A total of 25 items were used for expert validation. Empirical validation data were analyzed using the Rasch model. Review empirical validation from the aspects of item fit and unidimensionality. The analysis results show that I-4WADI has good quality based on validity and reliability. The infit MnSq values ranged from 0.81 to 1.40, and the outfit MnSq values ranged from 0.71 to 1.36. The instrument reliability value is 0.98. So, I-4WADI can be applied to high school students in Indonesia. These findings have practical implications for teachers who wish to diagnose students' misconceptions about waves and vibration.

Abstract

This research delves into the approximate relationship between the energy function (E) and the Hubble function (H) within cosmological. Utilizing the Friedmann equation, it establishes a link between the universe's scale factor and the Hubble function. Through Taylor series approximation, the study derives an approximation of the energy function, under specific assumptions and approximations. Asymptotic analysis investigates the behavior of variables y and s, shedding light on function limits and behaviors. The study incorporates an interactive 3D scatter plot visualization to elucidate the relationship between cosmological parameters and physical systems, aiding in a comprehensive understanding of dynamics. Practical recommendations emphasize increasing data points for accuracy and validating with observational data, while theoretical suggestions advocate exploring higher-order terms and considering additional physical factors.
