Four-Tier Multirepresentation Diagnostic Test for Identifying Students’ Misconception on Uniform Circular Motion
type: item
description: This study aims to analyze students' misconceptions on the topic of uniform circular motion using a four-tier diagnostic test based on multi-representation. The use of a four-tier diagnostic test based on multi-representation is expected to be able to identify students' misconceptions more deeply because it not only analyzes students' answers and reasons, but also the level of students' beliefs in various forms of representation, namely macroscopic, microscopic, symbolic, and graphic. This study used a quantitative descriptive method involving 100 high school students’ who had studied the material of regular circular motion. Data were analyzed by grouping students' answers into five categories, namely scientific conception, misconception, lack of knowledge, false positive, and false negative. The results showed that the misconception category had the highest percentage of 37.17 percent, which indicates that students still have difficulty in connecting concepts to various forms of representation. Misconceptions were more common in macroscopic and symbolic representations, especially in understanding the direction of centripetal acceleration and the relationship between quantities in regular circular motion. These findings indicate that students' conceptual understanding has not been fully formed. Therefore, physics learning needs to integrate various forms of representation so that students' conceptual understanding becomes more comprehensive. However, this study is limited to descriptive analysis in one school so that the factors causing misconceptions have not been studied in depth.

Development of IoT-Based Smart Home Media for Junior High School Electricity Learning
type: item
description: The development of automation technology demands that science learning, particularly electricity topics at the junior high school level, be supported by media relevant to current technological advancements. This study aims to develop a smart home media as an enrichment teaching aid for electricity materials and to analyze its validity, practicality, and students’ responses. Unlike previous studies that mostly focused on static and conventional electrical circuit visualizations, the novelty of this research lies in the integration of dynamic electricity concepts with Internet of Things (IoT)-based automation systems and microcontrollers (Arduino), packaged contextually for junior high school students. This study employed a Research and Development (R&D) method using the ADDIE model. The validation results indicated that the media was categorized as highly valid, with percentages of 82 percent from media experts, 96 percent from material experts, and 81 percent from learning experts. The practicality assessment by teachers reached 73 percent and 80 percent, categorized as fairly practical, while students’ responses reached 87 percent, categorized as very attractive. The smart home media is feasible to be used as a supplementary enrichment tool to introduce modern technology applications to students. However, this study has limitations regarding the scope of the trial subjects, which was limited to one school, and the evaluation focus, which only reached the feasibility stage and has not yet empirically tested the effectiveness of the media on improving students’ cognitive learning outcomes on a broader scale.

The Influence of Learning Motivation on Students’ Science Process Skills in Physics Learning From a Gender Perspective
type: item
description: Physics learning emphasizes not only conceptual mastery but also the development of science process skills (SPS), which are essential for fostering critical, logical, and creative thinking. Previous studies have examined the influence of gender or motivation separately, but little attention has been given to their combined effect. This study aimed to investigate the influence of learning motivation and gender, both individually and interactively, on students’ SPS in physics learning. A quantitative survey with a comparative design was conducted involving 200 ninth-grade students (92 male and 110 female) at SMPN 4 Singkawang, selected using saturated sampling. Data were collected through a 22-item learning motivation questionnaire and a 10-item SPS test, and analyzed using two-way ANOVA after normality (Sig. = 0.200) and homogeneity (Sig. = 0.340) assumptions were met. The descriptive results showed a mean SPS score of 40.07 with a standard deviation of 13.47. The ANOVA results indicated that learning motivation (F = 1.866, Sig. = 0.137) and gender (F = 2.465, Sig. = 0.118) did not significantly affect SPS when considered separately. However, the interaction between motivation and gender was significant (F = 4.559, Sig. = 0.004), demonstrating that the combination of these variables influences students’ SPS outcomes. In conclusion, individual factors alone do not determine SPS, but their interplay shapes students’ scientific abilities. Therefore, instructional strategies in physics learning should integrate motivational and gender-responsive approaches to effectively enhance SPS.

Profiles of Students' Logical-Mathematical Reasoning in Statistical Physics Learning: Differentiated Learning and Computer Simulation Perspectives
type: item
description: This study aims to analyze the logical-mathematical thinking ability of prospective physics teacher students as a basis for designing learning strategies based on differentiated learning and computer simulation. The survey method involved 37 physics education study program students from one of the universities on the island of Timor. Data was collected through a logical thinking ability test covering five main types of reasoning: proportional, variable control, probability, correlation, and combinatorial. The analysis results showed that most students were at the level of transitional logical thinking (70 percent), while only 11 percent reached the formal level. The chi-squared test showed a significant relationship between the semester level and students' logical thinking ability. These results show the need for learning that supports the transition from concrete and transitional thinking to formal. Implementing computer simulation in statistical physics learning is recommended to improve students' logical-mathematical thinking skills, support the understanding of abstract concepts, and facilitate the success of complex physics learning.

Enhancing Students’ Concepts Mastery in Kinetic Theory of Gases Through the STEM-Discovery Learning Model
type: item
description: Students' difficulties with gas kinetic theory material have led to low mastery of physics concepts. Improving mastery of the concept of the kinetic theory of gases can be supported by using learning models. There have been many studies that prove that discovery learning can influence physics learning outcomes. However, this study uses a STEM approach integrated into a discovery learning model that acts as part of the inquiry level in physics classes Merdeka curriculum. This research aims to improve students' mastery of concepts in the kinetic theory of gases material through the STEM-discovery learning model. This research used a one-group pretest and posttest design on 30 students of class XI Merdeka 4 at SMAN 1 Dolopo. The instruments used are the RPP and five questions describing the concept mastery test. The data obtained was then analyzed using the normality test, difference test, N-gain, and effect size, and categorizing the students' concept mastery level for each question. The results of this research reveal that STEM-discovery learning is able to increase students' mastery of concepts in kinetic gas theory material. Interestingly, this research also found that students' correct conceptions have not been able to be stored in memory very well, so it is necessary to link kinetic gas theory material to other physics material that is still relevant so that students are motivated to remember and retain concepts.

Graphical Analyzer Test of Misconception of 45o Angle as Optimal Angle in Projectile Motion
type: item
description: Misconceptions still often occur when learning physics, especially in conducting research that is not consistently detailed in identifying an observation. In parabolic motion material, it is known that 45° is a special angle that produces the farthest distance. The misconception that 45° is the angle that produces the farthest distance has become a reference in learning in various educational institutions to date. The aim of this research is to identify and prove that the 45° angle is not an elevation angle that produces the farthest distance in a vacuum that ignores the initial position of the thrower. This research was conducted using PhET virtual laboratory media which was analyzed based on quantitative and qualitative methods. This study will test the elevation angle of 42° : 45° : 48° based on altitude 0 m : 1 m : 2 m. After the observational data has been obtained and proven by the existing equations, the research results will be analyzed based on the functional analyzer approach by making the equations into function graphs to make it easier for readers to read the existing data. In this study, it was found that the angle of 42° is the producer of the farthest distance and also gets a relatively faster travel time compared to the angle of 45° which we know so far as a special angle that produces the farthest distance in non-vacuum conditions.

The Effectiveness of Technology-Based PhET Simulation-Assisted PBL Models to Minimize Misconceptions of Force and Motion Material
type: item
description: This study aims to determine the effectiveness of the Problem-Based Learning (PBL) model assisted by PhET simulation in minimizing misconceptions and improving students' conceptual understanding of force and motion material. The study used a quantitative approach with a pre-experimental design in the form of one group pre-test – post-test. The subjects of the study were grade VII students of SMP Negeri 2 Gebog. The instruments used were diagnostic tests based on the Certainty of Response Index (CRI) to identify misconceptions and pre-test and post-test tests to measure conceptual understanding quantitatively. The results showed that there was a decrease in misconceptions by 9 percent after the implementation of learning, as well as an increase in conceptual understanding with an average N-Gain value of 0.422348 or 42.23 percent, which is included in the moderate category. The Moving Man PhET simulation allows students to explore the relationship between motion variables visually and interactively, thereby helping to improve understanding of abstract concepts such as position, velocity, and acceleration. PBL which begins with the use of contextual phenomena successfully builds students' cognitive involvement and encourages critical thinking processes. Based on these results, the PBL model assisted by PhET simulation is considered quite effective as an alternative technology-based learning to overcome misconceptions and strengthen conceptual understanding of motion and force material.

Analysis of Student Participation in STEM-Based Robotics Lessons Using Transcript-Based Lesson Analysis
type: item
description: This study aims to analyze student engagement in STEM-based robotics learning at SMP IT Nurul Ilmi, Jambi City. The research was conducted using the Lesson Study approach and the Transcript-Based Lesson Analysis (TBLA) technique to examine student engagement based on the following indicators: actively working on learning tasks, asking questions to teachers or peers, seeking information to solve problems, participating in group discussions, assessing acquired skills/results, practicing similar problem-solving, and applying learning outcomes to new tasks. Data were collected through observations, audio recordings, and transcript analysis using Excel, presented in percentage form. The results show that the most prominent indicator was active involvement in completing learning tasks (38 percent), while the lowest indicators were practicing similar problem-solving (2 percent) and seeking information to solve problems (0.13 percent). These findings indicate that STEM-based robotics learning can foster student participation in core activities but has not yet fully developed scientific skills that serve as an essential foundation in science learning, such as observing phenomena, formulating questions, seeking information, and re-examining concepts through similar problems. Therefore, the implementation of robotics learning in the context of science education needs to be designed to train students in independent exploration, critical thinking, and transferring knowledge to new situations in accordance with the characteristics of science learning to support 21st century skills.

Analysis of Rainfall Patterns in Papua Using The Empirical Orthogonal Function
type: item
description: Indonesia as a tropical maritime country, experiences dry and rainy seasons influenced by geographical location, topography, winds, and climate phenomena such as ENSO and IOD. Although extensive research on rainfall patterns in Indonesia exists, specific studies on Papua remain limited. This gap leads to insufficient understanding of Papua's rainfall characteristics and dynamics, including dominant patterns and variability factors. This study aims to analyze rainfall patterns in Papua using the Empirical Orthogonal Function (EOF) method to identify dominant patterns and key modes of variability systematically. The EOF method is applied to extract dominant patterns from complex datasets, enabling spatial and temporal analysis of rainfall variability in the region. Analyzing rainfall patterns in Papua (1981–2015) using EOF combined with Machine Learning reveals that average rainfall intensity in Papua ranges from 0–9 mm per month. The EOF analysis identifies three principal modes explaining 62.53 percent, 11.39 percent, and 7.01 percent of total variance, respectively. EOF1 indicates dominant positive anomalies, while EOF2 and EOF3 show mixed positive and negative anomalies. Furthermore, rainfall variability in Papua is significantly influenced by interactions between the Indian Ocean Dipole (IOD) and El Niño-Southern Oscillation (ENSO), where positive IOD and El Niño phases contribute to dry conditions and reduced rainfall, while negative IOD and La Niña phases lead to wet conditions and increased rainfall.

Profile of Celestial Object Identification Skills of Junior High School Students in Indonesia
type: item
description: The ability to identify celestial objects provides significant benefits for improving students' motivation, understanding of the subject matter, reasoning, and skills, yet this area remains underexplored by researchers. This study aims to describe the profile of junior high school students' ability to identify celestial objects in science learning, particularly in the Solar System topic, focusing on their experiences in recognizing the names of celestial objects at night. Using a qualitative approach, this research involved semi-structured interviews with three science teachers and a survey of 31 7th-grade students who had not been taught the Solar System topic. The research instruments included student characteristics, availability of learning resources, challenges faced by students, teaching methods, and responses to the idea of outdoor learning with the assistance of an Augmented Reality (AR) application. The results indicate that, generally, students are not yet able to identify celestial objects other than the Moon due to limited prior experience and knowledge. Although teachers have attempted to introduce identification methods through instructional videos and direct explanations, this method is considered less accurate due to discrepancies between classroom learning and field experiences. However, both teachers and students recognize that identifying celestial objects can enrich understanding of the subject matter, increase motivation, and stimulate gratitude for God's creation. The positive response to the idea of outdoor learning with an AR application indicates high interest from both teachers and students in this approach.
