Abstract

This research aimed to investigate the implementation of Case-Based Learning (CBL) with a contextual approach to enhance students’ problem-solving skills in dynamic fluids. The study employed a pre-experimental design with a one-group pretest-posttest, involving 33 eleventh-grade students from a senior high school in Bandung. A 20-item essay test assessed five aspects of problem-solving skills based on Heller’s (1992) framework: visualize the problem, physics description, plan a solution, execute the plan and check and evaluate. Data analysis included N-gain, Wilcoxon signed-rank test, and effect size (Cohen’s d). Results indicated that students’ problem-solving skills improved moderately across all aspects, with an average N-gain of 0.5. The Wilcoxon test revealed a significant increase in posttest scores (p < 0.05), and the effect size was very high (d = 2.6), indicating a strong impact of the intervention. These findings demonstrate that the implementation of CBL with a contextual approach is effective in enhancing students’ problem-solving skills, fostering deeper understanding, and promoting active engagement in learning dynamic fluids.

Abstract

Ionic thermoelectric (i-TE) materials have the potential to be applied to devices for converting low-temperature heat energy into electricity. In this study, an I-TE cell made of PVA/glycerin/H3PO4 was synthesized using Al and Cu electrodes. The general objective of this study is to investigate how symmetrical electrode configurations (Al-Al, Cu-Cu) and asymmetrical configurations (Al-Cu) affect the thermoelectric performance of PVA/glycerin/H₃PO₄ polymer electrolyte cells, including potential difference, Seebeck coefficient, and power factor. The results of this study show that the PVA/glycerin/H₃PO₄ sample with asymmetric electrodes produces a higher potential difference than the sample with symmetric electrodes. The highest potential difference in the sample with asymmetric electrodes is 0.97 V. Meanwhile, the highest potential difference produced by the sample with symmetrical Al electrodes was 0.15 V. However, the highest increase in potential difference with respect to temperature gradient was observed in the PVA/glycerin sample with symmetrical Al electrodes. This was based on the Seebeck coefficient value produced by the sample, which was 16 mV/K. This is followed by the sample with an asymmetric electrode, and the lowest is the sample with a symmetric Cu electrode. The power factor of the sample increases with increasing temperature and follows the pattern of increasing ionic conductivity. In addition, the power factor is also influenced by the Seebeck coefficient value of the sample. In this study, samples with symmetrical Al electrodes showed the highest PF values, with a maximum value at a temperature of 65 °C. These findings indicate that polymer electrolyte cells based on PVA/glycerin/H₃PO₄ with Al and Cu electrodes have the potential for use in i-TE devices to convert low-quality thermal energy into electricity.

Abstract

The understanding of the physics concept of viscosity is often hindered by its abstract nature and the limited availability of experimental tools in schools, leading to theoretical and suboptimal learning. Therefore, an innovative learning package needs to be developed to address these issues. This study aimed to develop this learning package and to test whether the resulting product is valid, practical, and effective for enhancing student's conceptual understanding. This study is a research and development adapting the procedural framework of the ADDIE model. The process involved 11th-grade SAINTEK students at SMAN 11 Mataram as trial subjects, with feasibility data collected through expert validation sheets, response questionnaires, and pretest-posttest questions for quantitative analysis. The data analysis indicated that the developed learning package consisting of an Arduino Nano-based viscometer, a teaching module, a student worksheet, and a test instrument achieved a very valid rating (average >89%), a very practical rating (92.00%), and was sufficiently effective with an average N-Gain score of 0.51 (medium category). Based on these results, it is concluded that the developed learning package is valid, practical, and sufficiently effective to be used for enhancing students' understanding of physics concepts.

Abstract

The demands of formative assessment in the kurikulum merdeka should ideally be able to diagnose students’ conceptual patterns in depth. However, common assessment practices are still limited to instruments that only measure correct or incorrect answers, so they cannot reveal conceptual understanding. The gap between these demands and reality has led to the development of more targeted instruments, especially for complex thermodynamics material. This study aims to develop a formative assessment instrument in the form of a misconception check to analyze high school students’ conceptions of thermodynamics. The method used is quantitative with an instrument development approach based on the Mardapi model. The developed instrument is a formative assessment tool in the form of a misconception check with a multiple-choice format, with answer options designed to represent various categories of conceptions. The instrument was tested on 262 students from three high schools, and its validity was evaluated through content validity, construct validity, and readability tests. After a series of evaluations, it was found that 3 items were invalid and were eliminated, leaving 33 items that were suitable for use. This instrument has a unidimensionality value of 21%, an average Aiken's V coefficient of 0.96, and reliability of 0.92. The results of the study indicate that the developed formative misconception check assessment instrument is feasible and effective for analyzing the conceptions held by high school students on thermodynamics material. Therefore, this instrument can help teachers specifically analyze students' conceptions and design targeted learning.

Abstract

This study aims to determine the effect of the Project Based Learning (PjBL) model on the physics learning outcomes of eleventh-grade students on the topic of dynamic fluids. This research employed a quasi-experimental method with a pretest–posttest control group design. The population consisted of all eleventh-grade students of SMAN 2 Praya, totaling 170 students across five classes. The sample was selected using cluster random sampling and consisted of class XI-5 as the experimental class, which received the PjBL treatment, and class XI-3 as the control group, which received conventional instruction, with 34 students in each group. Cognitive learning outcomes were assessed using a multiple-choice test consisting of 20 validated and reliable items, while affective and psychomotor outcomes were measured using observation sheets. The hypothesis tested concerned the influence of the PjBL model on students’ physics learning outcomes. Data analysis began with prerequisite tests (normality and homogeneity). Since the data were not homogeneous and not normally distributed, the Mann–Whitney test was used for hypothesis testing. In addition, the N-Gain test was conducted to determine the improvement in learning outcomes. The Mann–Whitney test produced a significance value of <0.001, which is lower than 0.05, indicating that H₀ was rejected and Hₐ was accepted. The N-Gain results showed that the experimental group achieved a high category, while the control group fell into the low category. These findings indicate that the Project Based Learning (PjBL) model has a significant effect on students’ physics learning outcomes.

Abstract

This study aims to analyze the impact of the implementation of PhET simulation-assisted deep learning on students' problem-solving skills by considering their level of learning motivation. The research method used a quasi-experimental design with a 2x2 factorial model. The research subjects involved two classes: an experimental class that received PhET simulation-assisted deep learning treatment and a control class that received conventional learning. The research instruments included a problem-solving skills test in the form of essay questions and a validated learning motivation questionnaire. Data analysis was conducted using a two-way ANOVA test to examine the effect of learning methods, motivation levels, and their interaction on problem-solving skills. The results showed that PhET simulation-assisted deep learning significantly improved problem-solving skills compared to conventional learning. Students with high learning motivation achieved better problem-solving scores than students with low motivation, both in the experimental and control groups. In addition, there was a significant interaction between learning methods and learning motivation, where students with high motivation who participated in deep learning showed the highest improvement in problem-solving skills. These findings confirm that PhET simulation-assisted deep learning is effective for developing critical thinking and problem-solving skills, especially in students with high learning motivation. The implications of this research encourage educators to integrate in-depth learning and technology-based interactive media in the science learning process, as well as pay attention to strategies for increasing learning motivation as an important factor in achieving optimal learning outcomes.

Abstract

The city of Bengkulu is the capital of Bengkulu Province, which is the main center for government, health, and education activities. As the capital city, infrastructure development is important due to its proximity to the subduction zone. This study analyzes how the Tino Galo hospital building responds to seismic performance. The study began with a comprehensive field survey to collect geological information at the study site. Referring to various earthquake events at the study site, it is known that earthquakes triggered by subduction are the dominant type of earthquake that occurs. The seismic response of the soil was then evaluated to identify soil movement characteristics, including important parameters such as peak ground acceleration (PGA), spectral response acceleration, and amplification factor. The next step was to simulate earthquake wave propagation using three-dimensional modeling with the Finite Element Method (FEM) to assess the structural response of the building to earthquake shocks. The analysis results show that after evaluation using time history data from both earthquake waves, the building structure elements are in a safe condition. These findings imply that the current structural design can effectively withstand and distribute earthquake loads, so that no dimensional changes or additional reinforcement are required for the Hospital Building. This study recommends the continued application of a combined soil response and structural dynamics analysis method for buildings in earthquake-prone zones, as well as the need to utilise a broader range of earthquake data to improve the accuracy of seismic performance evaluations and support the development of future risk mitigation strategies.

Abstract

In this paper, we present a step-by-step description of a student project that illustrates the application of Lagrangian and Hamiltonian mechanics to a two-degree-of-freedom system. As part of the project, students explored both formalisms' peculiarities, identified conservation laws, and calculated integrals of motion. Students gained valuable experience by working with different approaches and observing the consistency with which they achieved equivalent results. The study has been fulfilled with a single cohort of fourteen undergraduate students. Each student received an individual version of the project with different initial conditions. Students uploaded the completed projects in a form of a brief report to a learning platform Moodle. The next stage was the teacher’s review of the project and its evaluation. An evaluation was conducted for each of the three parts of the project, described in detail in the paper. After that, an individual meeting was held with each student to clarify the evaluation result. As part of this meeting, the student was surveyed about what was the most difficult and whether the result matched the expectations. Analysis of the assessment data showed a 20% improvement in conceptual understanding and demonstrated that all students could successfully apply both Lagrangian and Hamiltonian approaches to the physical system being modelled.

Abstract

This study analyzes the creative thinking abilities of Grade 11 students at SMAN 14 Gowa on the topic of dynamic fluids. The researchers employed a quantitative descriptive design using a survey method. The study involved 82 students selected through purposive sampling. The researchers collected data using five validated open-ended questions, each representing an indicator of creative thinking ability: fluency, flexibility, originality, and elaboration. The results indicated that, overall, students’ creative thinking ability was categorized as fairly creative, with an average interval score of 14.7. Among the indicators, fluency showed the highest achievement (62.20%), classified as high, followed by flexibility (59%), elaboration (56%), and originality (52%), all of which fell into the moderate category. These findings suggest that students demonstrate strength in generating multiple ideas; however, further instructional support is needed to enhance their ability to produce original ideas and to develop and explain ideas systematically.
