Abstract

Mathematics remediation (MR) is crucial in higher education, serving as a cornerstone to prepare under-equipped students. However, numerous Mathematics Education students in one of the public universities in Indonesia have repeatedly failed in this program. Failure experiences have an essential role in pre-service mathematics teachers' personal and professional development. While some research has explored the students' failure experiences, a significant gap exists in exploring the perception of repeatedly failed students in MR. Our qualitative narrative case study delves into the perceptions of repeatedly failing students regarding the MR and their failures. Five themes emerged through analysis of reflective writing and interview data: perceptions of mathematics and its learning, perspectives on the MR program, attitudes toward failure, factors contributing to participant failures, and expectations for MR program development. This study provides valuable insights to enhance the effectiveness of MR, shedding light on the intricate dynamics surrounding students' experiences with the program.

Abstract

It is necessary to emphasize the ability to conceptual understanding of geometry (CUG) for each student to support the formation of mathematical competence. In forming, it is important to carry out a lesson by prioritizing interaction between students in conveying ideas known as sociomathematical norms. The construction CUG is very important for learning by prioritizing interaction between students in conveying ideas known as socimathematical norms. The aims of study to analyze the implementation of the discovery learning (DLM) in developing achievements of CUG based on aspects of socio mathematical norms in learning plane geometry. This study used a quasi-experimental method by following a nonequivalent control group design. The sample involved in this research was 70 students of the mathematics education study program. This study concludes: 1) Achievement of students' CUG by implementing DLM is better than achievement of students' CUG by applying the conventional model (CM). 2) there is are significant differences between the achievement of students' CUG using DLM and students applying CM based on the socio mathematical norm level; 3) there is an interaction effect between DLM and sociomathematical norm factors on achievement of students' CUG; 4) the contribution of DLM implementation to student CUG achievement includes: (a) Student Worksheets with DLM syntax make it easier for students to deepen geometry material; (b) a discussion process that gives rise to students' freedom of expression; (c) the diversity of alternative problem solving strengthens students in determining the best choice and analysis of problem solving; (d) classical presentation activities motivate students to understand the concepts in each lesson.

Abstract

This study aims to analyze students' cognitive processes through minimum competency assessment questions. This study uses a qualitative research approach with a descriptive method to describe the mental process of students using minimum competency assessment questions that are carried out at the beginning of learning. The results showed that 13 out of 22 students could use previous knowledge and explain how they used it to understand the text, 21 could identify important and relevant ideas, and as many as 9 students were able to make realistic inferences and cite supporting evidence. Most students cannot yet think mathematically and can solve the given problems. This study also found that as many as 19 students were able to define all vocabulary and be able to explain it. Eighteen participants could not understand the multimodal text, and showed that 11 students were quite able to show how to understand the text even though it was incomplete. Teachers can use this data for initial data as a reference for implementing learning strategies for future teaching.

Abstract

The aim of this research was to find out how prospective mathematics teachers can visualize the form of fractional division operations based on mathematical literacy skills. This research includes qualitative research with descriptive methods. This study was conducted on 3 students of the 3rd semester mathematics education program with high, medium and low mathematical ability with good communication skills. Researchers gave three questions on literacy tests. The tests given include problems related to division of integers by fractions, division of fractional numbers by integers and division of fractional numbers by fractional numbers. From the test results obtained, interviews were conducted of all three subjects. The results showed that all three subjects were able to understand and translate the questions and formulate what was asked of the questions. However all three subjects encountered constraints when trying to visualize the form of division of fractions by fractional numbers. They just memorize division formulas like “multiplying and inverting”. From the results of the data analysis, it can be concluded that the literacy ability of the subject in visualizing the form of the division operation is still classified as low.Keywords :  Mathematical Literacy, Visualizing, Divison of Fraction.

Abstract

Students' failure to grasp mathematical concepts can impede their mastery of learning standards, necessitating remedial efforts often constrained by time. Video-based remedial learning emerges as an innovative solution to enhance learning effectiveness. This study assessed the improvement in student outcomes following video-based remedial learning. Using an experimental pretest-posttest design, the study involved 100 Year 11 and 12 students from a public high school in Sukamakmur, Aceh Besar, Indonesia. Data analysis, via N-Gain score and t-tests, revealed three key findings: (1) a notable improvement in student outcomes after video-based remedial learning on trigonometric comparisons, (2) a greater enhancement in science classes compared to social studies classes, and (3) a higher increase in Year 12 compared to Year 11. The results affirm that video-based remedial learning positively impacts students' understanding of trigonometric functions

Abstract

Many ethnomathematical studies focus on Indonesian culture, particularly traditional dwellings, although research into the mathematical notions of the Tajug House is sparse. There has been no previous research that examines the Tajug House form the aspect of geometry. Tajug houses are becoming increasingly rare. Nowadays students are less familiar with traditional house types. As a result, this study investigates the mathematical principles found in traditional Tajug houses in Java, and how these notions might be integrated into educational curriculum to conserve cultural heritage while also improving mathematics learning. This study used an ethnographic approach, to investigates the Tajug House's design through a literature review, expert interviews, and observations. The data obtained were analyzed based on mathematical and Tajug House knowledge by author to see the existence of mathematical concepts in the tajug house. The findings reveal significant geometric concepts, including plane geometry (square, triangle, trapezoid), solid geometry (cuboid), and geometric transformations (reflection). Square found in the base of the house, triangle found in the side of the roof, and trapezoid found in the base of pillar. Cuboid found in the pillar. Reflection found in the base of the house. These results suggest that Tajug Houses can effectively become one of the learning media to geometry subject in schools, demonstrating practical ethnomathematics applications. The learning process can utilize the GeoGebra application. By linking cultural heritage with mathematical education, this research promotes a deeper understanding of both subjects. Future studies should evaluate the effectiveness of Tajug House-based learning in improving students' math comprehension and cultural appreciation.

Abstract

This research is motivated by the results of observations which show that the results of the three-dimensional daily assessments and end-of-semester assessments are still not optimal. This is influenced by several factors, especially the student's interest in learning in class. They still have difficulty visualizing the three dimensions so in calculating the questions given, they still experience difficulties completing them. Three-dimensional material requires a good understanding of the shapes of three-dimensional space and related concepts. Therefore, the Augmented Reality (AR) feature is needed in the Geogebra application. This research aims to analyze students' learning interests by using the Augmented Reality (AR) feature in the Geogebra application. This research used a qualitative approach where the research subjects were 61 students consisting of 33 students in class XII IPA 1 and 28 students in class XII IPS 1 at SMAIT Raudhatul Jannah Cilegon. The research results show that the presentation of each indicator on the student interest scale questionnaire has an average of 80.19%, which means that almost all students already have an interest in learning three-dimensional material using the Augmented Reality (AR) feature in the Geogebra application. It is hoped that other researchers can develop the results of this research, as well as improve the quality of learning, especially in mathematics learning with the help of the Geogebra application to increase insight.

Abstract

The critical problem in this research is the lack of instructional strategies that simultaneously enhance literacy and numeracy skills while addressing students' diverse learning needs. While the Problem Based Learning model fosters problem-solving, its implementation often overlooks individual differences, making its integration with differentiated instruction crucial and challenging. One of the mathematical skills that students must have is literacy numeracy skills. However, based on initial observations at one of the public senior high schools in Kuningan, students' literacy and numeracy abilities are still low. This study aims to examine the effectiveness of the Integrated Problem Based Learning Differentiated Instruction model in improving high school students’ literacy and numeracy skills. The research employed an experimental method with a one-group pre-test and post-test design involving 36 class XI students. Data were collected through literacy numeracy tests administered before and after the intervention. Data analysis was conducted using N-gain to measure the improvement in students' literacy numeracy ability. The research results were obtained from test results N-Gain, with scores of 0.56 (medium category) and an increase percentage of 56.05%. Students show better abilities in understanding, interpreting, and analyzing problem-based questions related to mathematical concepts
