Abstract

The matter of algebraic form is crucial to study because the matter of the algebraical form is not only related to other mathematical matters but also related to everyday life, but there are still many students who have difficulty in communicating the explanation of the origin of the algebraic form. This is because the learning media used by the teacher is not interactive, so it affects the student's understanding and communication skills. For this reason, the study aims to cultivate the interest in learning and cultivate students' mathematical communication skills by developing algebraic learning media supported by a PowerPoint application. The method used in this research is research and development, with the development of a modified 4-D model in three stages namely determining, designing, and developing.  The tool used to measure the quality of the learning media is a validation questionnaire for measuring the validity and student response to strengthen practicality. The results of this study show that the quality of the learning media meets the valid criteria with an overall average score of 79% and From the test carried out against students obtained an average scoring of 76%. Thus, the development of algebra learning media supported by the PowerPoint application has good quality and can be used in mathematical learning.

Abstract

This research is motivated by the importance of students’ mathematical connection abilities and self-confidence in learning mathematics. Mathematical connection ability is an important factor in understanding mathematical concepts. The aim of this research is to analyze the level of students’ mathematical connection abilities and junior high school students’ self-confidence. The method used in this research is a descriptive-qualitative method. The research subjects were 37 students in class VIII-C of SMPN 3 Margahayu. The instruments used were four items of mathematical connection test material on the System of Two-Variable Linear Equations and non-tests of students’ confidence in learning mathematics. The results of the analysis show that the average score of all mathematical connection ability test questions in indicator 1 using relationships between mathematical topics is 5%, indicator 2 is understanding equivalent representations of the same concept (36%), indicator 3 uses mathematics in everyday life (52%), and indicator 4 uses mathematics in other subjects (27%). So the average is 30%. So the students’ mathematical connection ability is included in the low category. Most students are unable to solve problems with indicators using relationships between mathematical topics. This is shown by the results of the mathematical connection ability test; students did not connect optimally. But in learning mathematics, students already have good self-confidence.

Abstract

Students' understanding of linear equations with one variable is still low. Of the total number of students in the class, namely 32 students, only 10 students scored above the minimum completeness criteria (KKM) while the remaining 22 scored below the KKM. This research aims to determine the improvement of mathematical communication skills by using problem-based learning better than ordinary learning. Two classes, an experimental group, and a control group, were selected for this study. The researchers tested the technique because experimental research requires both groups to have the same skill level. The researcher used a test of students' mathematical communication skills as a research tool in this study. The average N-gain score for students who apply the problem-based learning model with regular learning is 0.71 (high category), higher than students who receive regular learning. of 0.10 (low category). Then the N-gain score normality test was carried out, the results obtained were 0.023 in the experimental class and 0.216 in the control class and the results obtained were not normally distributed. Then proceed with non-parametric tests, from the results of the Mann-Whitney U-Test obtained by Asymp. Sig (1-tailed) is 0.000 ˂ which indicates it is rejected, meaning that the increase in mathematical communication skills of experimental class students is significantly better than that of the control class. The PBL model improves students' mathematical communication by promoting critical thinking, collaborative work, and active problem-solving. It also allows students to understand the practical relevance of mathematical concepts in real-life situations.

Abstract

While mathematics is immensely imperative and regarded as a fundamental subject serving as one of the graduation requirements at every level of education in Indonesia, including vocational schools, adverse perceptions associated with it as a challenging subject are deeply ingrained in society, particularly among students. Despite there is a wealth of research exploring math anxiety and elf-regulated learning, a discernible gap exists in the literature, specifically within the Indonesian context, particularly among Vocational Students in the Bandung area. This research aims to explore the predictive relationship between math anxiety and students' self-regulated learning within the context of vocational education. Employing linear regression statistical analysis, and survey data collection method, this quantitative study involved 99 participants from two vocational schools in Bandung Regency. The results indicate a statistically significant impact of math anxiety on students' self-regulated learning. However, it's noteworthy that the degree of correlation is considered low. Furthermore, no significant differences were identified concerning variables such as age, sex, streaming, and class level. These findings contribute to the understanding of the dynamics between math anxiety and self-regulated learning, particularly within the context of vocational education in the Bandung region, and can serve as a valuable insight for future research in similar topics.

Abstract

This research is a qualitative descriptive study which aims to describe the problem solving process of a professional teacher in finding solutions to problems of the Problem With Contradiction Information type. This research involved 1 mathematics teacher who had a professional teacher education certificate and had taught for at least 5 years (S1) and 1 mathematics teacher who had taught for at least 5 years but did not yet have a professional teacher education certificate (S2) and 1 prospective teacher who was still carrying out studies. S1 and does not yet have a professional teacher education certificate (S3). Data collection was carried out by tests and interviews. The research results showed that only S3 carried out all the IDEAL problem solving indicators and was the only research subject who realized the existence of contradictions in the given problem. Meanwhile, S1 and S2 do not look back and learn. All subjects started solving the problem by reading and making propositions from the problem given. S3 stated that he read twice, namely reading in depth and reading quickly to review the known data. S1 experienced Pythagorean priming when implementing the Making a Drawing and Backwards strategy. Meanwhile, S2 in implementing the Backwards strategy often has to do some work in his working memory so there are several steps that are not written down. S2 is aware that there is unnecessary data but considers it an open ended question. Meanwhile, S3 succeeded in stating that the question contained elements of contradiction and could not be done in the anticipating outcome and looking back steps. If you want to become a good problem solver then spend most of your time identifying and understanding problems and then determining how to work. Good problem solvers are not in a hurry but are still effective in solving problems. You even need to consider whether the problem can be solved or not.
