Abstract

Effective collaboration in mathematics learning is essential for developing students' critical thinking and problem-solving skills; however, identifying patterns that lead to successful group collaboration remains challenging. This study aims explicitly to identify and classify the patterns of student group assignment completion in the Logic and Sets course using the Naïve Bayes algorithm. Survey data from 65 mathematics education students were analyzed using a quantitative approach and machine learning techniques. Attributes such as group size, task completion time, participation, contribution strategies, and communication effectiveness were collected via structured questionnaires. Data analysis involved preprocessing, model training using Naïve Bayes, and validation through accuracy and posterior probability analysis. Results indicated that the Naïve Bayes model accurately distinguished groups with very good (A) and fairly good (B) performance, achieving 84.62% accuracy. Groups achieving an A grade typically featured balanced participation and open communication strategies, whereas groups graded B exhibited uneven participation and passive members. This research significantly contributes by demonstrating how data-driven predictive analytics can support instructors in monitoring and enhancing collaborative learning processes in mathematics courses. Future research could further refine predictive accuracy by incorporating additional factors such as leadership style and collaborative technologies, potentially integrating the model into learning management systems for real-time evaluation and intervention.

Abstract

This study was conducted to improve the mastery of student concepts on calculus materials using Quantum Learning method, this research is motivated because the learning of calculus has not seen any mastery of concept implemented during learning. Therefore formulated problems in this research is how the implementation of learning calculus by using the method of Quantum Learning, and how to increase the mastery of concepts on learning calculus mathematics by applying the method of Quantum Learning. The purpose of this study is to determine the ability to understand mathematical concepts of students who obtain learning Quantum Learning and students who obtain conventional learning. The type of research is a quasi-experiment with the design is Posttest-Only Design. The sample in this research is a student of 3rd semester of Muhammadiyah Metro University. The technique of data collecting using ability comprehension test of mathematical concept and hypothesis test using t-test. From the result of hypothesis test using t test that is tct = 4,136 and ttable = 2,035 which show at significant level α = 0,05 yield tcount> ttable and states that H0 is rejected means ability of comprehension mathematical concept of a student who gets learning of Quantum Learning is higher than student Who acquired conventional learning.

Abstract

The ability to think critically is one of the abilities that must be possessed by students in facing the rapid development of the times. Students' critical thinking skills can be developed through Socratic questions. This research is to find out 1) the types of Socratic questions used in learning and 2) whether Socratic questions can optimize students' critical thinking skills. The method used is a qualitative and quantitative approach with a pretest-posttest one group design. The research subjects were mathematics education students who attended linear algebra courses at Muhammadiyah Metro University. Data collection was carried out through observation and tests with descriptive qualitative and quantitative data analysis techniques. Socratic questions asked by lecturers in learning linear algebra include questions of clarification, investigative assumptions, reasons, investigative evidence, and beliefs. Socrates' questions can stimulate students' critical thinking activities to strengthen their understanding of concepts. Students' critical thinking skills increased in the medium category. The types of Socratic questions used in learning are distinguished based on three stages, namely in the introduction stage, the types of questions asked by the lecturer are clarification questions. At the core stage, Socratic questions include questions of clarification, investigative assumptions, evidence/reasons, and beliefs. And in the concluding stage, Socrates' question is a clarifying question. Socratic questions used in learning can optimize students' critical thinking skills. The results of this study are expected to be a reference for lecturers in applying Socratic questions in learning, especially in linear algebra courses.

Abstract

The purpose of this study is to evaluate the effectiveness of the Geogebra app in facilitating the discovery learning paradigm in mathematics instruction for junior high school pupils. The experimental technique is used for the investigation. Using Simple Random Sampling, 17 students from the eighth grade boys' class and 20 students from the eighth grade girls' class served as the experimental and control groups, respectively. The assessment tool used is an essay-based exam. Observation, interviews, documentation, and testing are all methods of data gathering, and a t-test is used for data analysis. The study found that compared to traditional learning models, the discovery learning model with the use of the Geogebra app had an effect size of 2.143>2.030, indicating a relationship between the two. This is due to the fact that students are motivated to actively participate in problem-solving via the exploration of their own talents, investigation of the issue, and eventual solution, all of which are supported by the discovery learning paradigm and made possible by the Geogebra program. It follows that Geogebra's discovery learning methodology affects Sunan Ampel Punggur Middle School students' performance in the classroom

Abstract

Children with autism often face challenges in recognizing and controlling their own bodies, a condition referred to as body awareness. Deficits in body awareness can significantly affect motor skills, nonverbal communication, and social interaction. Despite the importance of this developmental domain, interactive training media tailored to the sensory and cognitive needs of children with autism remain limited. This study aims to develop an Android-based application to enhance body awareness in children with autism through the integration of music, video, and mirror game activities. The research utilized the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model. Instruments included expert validation questionnaires for both content and media, as well as user response surveys and comprehension tests administered to 30 children with autism in Metro City. Validation results indicated high feasibility, with ratings of 88.75% from media design experts and 90.00% from content experts. Effectiveness testing revealed a statistically significant improvement in body awareness, with a 20-point gain between pre-test and post-test scores (t = 13.70; p < 0.001; 95% CI: 16.70–23.30). These results suggest that the developed application is a practical, engaging, and effective tool for supporting body awareness development in children with autism, and it may serve as a valuable resource for educators, therapists, and parents.
