Abstract

The study was to create a problem using wordwall and to evaluate its impact on the learning achievement of class iii students in round numerical materials. The background of this study is based on the problem of students' low interest and motivation in following the traditional mathematical learning assessments through the issues written in the package book. These circumstances leave many students feeling bored, diminished in zeal, even resulting in a decline in their study. The methods used in the study are research and development (randd) with addie models, consisting of analysis, design, development, implementation, and evaluation. The subject of this study is 20 students from class iii at the islamic school tahfidz darul mujahideen n majidi. The instruments used include a validation sheet from materials and media experts, a teacher and student response questionnaires, and pre-test and post-test results. The results from research indicate that it was a very valid t-wall evaluation, with the validation score of materials by 96.92% and media experts by 90.6%. In terms of practicality, the teacher's response is very positive, reaching a percentage of 96%, while the students give a positive assessment of this media by a percentage of 90%. In terms of effectiveness, there is seen an average increase in students' grades from 50 on pre-test to 85 on post-test. N-gain value by 0.7 shows a high category, which means wordwall use has proved to be effective in improving learning. Thus, the study asserts that development on wordwall assessments can be an innovative alternative to improved learning assessments, especially in elementary school numerical multiplicity.

Abstract

This study aims to explore the phenomenon of time dilation based on the Special Theory of Relativity through the Walter Fendt Relativity Simulation. The main problem in this research is how the relative velocity of an object affects the difference in time rates between two observers in different reference frames. The research employs a virtual experimental method with a descriptive quantitative approach. Data were obtained from simulations with relative velocities of (v/c = 0.3, 0.6, 0.8, 0.9, and 0.95), which were then compared with theoretical calculations using Einstein’s time dilation equation. The results indicate that as the relative velocity increases, the time difference between the two observers becomes greater. The percentage of agreement between the simulation and theoretical results shows a very small deviation, indicating that the Walter Fendt simulation has good validity in representing the concept of time dilation. These findings suggest that virtual simulations are effective in enhancing the understanding of relativistic concepts in modern physics learning.

Abstract

The low accuracy and objectivity of manual evaluation of mathematics learning in higher education impacts the quality of student research. This study aims to develop an Artificial Intelligence (AI)-based evaluation model to improve the effectiveness of assessment and the quality of mathematics education research. The method used was Research and Development (R&D) with a modified Borg & Gall model, encompassing needs analysis, design, expert validation, and limited trials. The resulting model consists of four main components: Data Input, AI Processing, Assessment Output, and Feedback System, all connected through a feedback loop. Validation results showed a "very valid" validity level (average >3.6), while trials demonstrated a 25–30% increase in assessment consistency between lecturers. The AI system was also able to detect student conceptual errors quickly and accurately. The results confirm that this model is effective in improving the objectivity, efficiency, and quality of student research. The study recommends the development of a machine learning-based feedback loop and the integration of the model into the campus Learning Management System (LMS).

Abstract

The objective of this study is to determine the feasibility of a geometry teaching module design based on Realistic Mathematics Education (RME) to improve students' learning outcomes. It also aims to identify the improvement in elementary school students' geometry problem-solving skills through the implementation of the RME-based geometry teaching module. This research is a type of development research (Research and Development) using the 4D development model proposed by Thiagarajan. In this study, the researcher implemented the 4D development procedure only up to the third stage, namely development, since the focus of this study is solely on developing a problem-based module using the RME approach. The instruments used for data collection were questionnaires administered to expert validators, including subject matter experts and learning design experts. Based on the research results, the RME-based geometry teaching module design is considered highly feasible for improving the learning outcomes of fifth-grade students at SD Negeri 101797 Deli Tua. The geometry problem-solving skills of elementary school students showed a significant improvement through the implementation of the RME-based teaching module. The pre-test results before using the module showed an average student problem-solving score of 30.4. After using the teaching module design, the average score increased to 85.3. Therefore, the RME-based teaching module is highly recommended for enhancing students' problem-solving abilities in the topic of two-dimensional geometry.

Abstract

Differences in students’ learning styles often affect learning outcomes, particularly in abstract and conceptual subjects such as chemical bonding. This study aims to examine the influence of learning styles on the learning outcomes of Grade X students in the topic of chemical bonding. A comparative quantitative approach was employed using an ex post facto design. The sample consisted of 75 students selected through a saturated sampling technique. Data were collected through a learning style identification questionnaire and documentation of daily test scores. Data analysis was conducted using a One-Way ANOVA test followed by the Tukey HSD test. The results showed that learning styles had a significant effect on learning outcomes (p = 0.027), with students with an auditory learning style achieving the highest average scores. Significant differences were found between auditory and kinesthetic groups, as well as between visual and auditory groups. These findings emphasize the importance of aligning instructional strategies with students’ learning styles to enhance learning effectiveness. Observations also revealed that kinesthetic learners showed lower engagement, indicating the need for more active and exploratory learning approaches. This study recommends that teachers map students’ learning styles as a basis for designing responsive and adaptive instruction, especially for complex chemistry topics.

Abstract

The background of this study is the low level of student participation, critical thinking skills, and collaboration abilities, as well as suboptimal learning outcomes in IPAS, particularly in IPS material. This condition is caused by the dominance of one-way teaching methods, limited innovative learning models and media, and minimal opportunities for students to discuss, collaborate, and actively participate. To address these problems, the Problem Based Learning (PBL) model was implemented, combined with the GNM model (Group Investigation, Numbered Heads Together, and Mind Mapping) and the traditional game Cublak-Cublak Suweng. This study is a Classroom Action Research (CAR) conducted over three meetings with 20 fourth-grade students at SDN Simpang Empat, Banjar Regency, in the even semester of the 2023/2024 academic year. Data were collected in both qualitative and quantitative forms through observations of teacher activities, student activities, critical thinking skills, collaboration skills, and learning outcomes. The success criteria were set if at least 80% of students were categorized as “Very Active” and 80% achieved scores ?72. The results showed improvements from the first to the third meeting, where teacher and student activities reached the “Very Good” and “Very Active” categories, critical thinking and collaboration skills improved to “Very Skilled,” and the learning completeness reached 85%. Therefore, the implementation of PBL combined with GNM and traditional games has proven effective in enhancing the quality of IPAS learning
