Abstract

This research was motivated by the low mathematical communication skills of class VIII students. The aim of the research is to analyze the effectiveness of implementing the Discovery Learning model on students' mathematical communication skills, by comparing the experimental class that uses the Discovery Learning model and the control class that uses conventional learning. This research method is quasi-experimental with a pretest-posttest design in two groups (Pretest-Posttest Control Group Design). The research subjects consisted of students from class VIII-A as the control class and VIII-B as the experimental class, each numbering 25 people at SMP Negeri 2 Takokak. The data collection technique uses instruments to test students' mathematical communication skills on the System of Linear Equations in Two Variables (SPLDV). Students' mathematical communication ability tests were given twice at pretest and posttest. Data processing and analysis uses the Microsoft Excel 2021 application and SPSS 25 software. The results of the research show that the effectiveness of students' mathematical communication skills who learn through the Discovery Learning model is better than conventional learning.

Abstract

The research aims to investigate the achievement of students' mathematical representation abilities in the material of flat-sided space after receiving a problem-based learning model. This study employs a quasi-experimental method with a non-equivalent control group design, as there is no randomization of samples in both classes. The population consists of eighth-grade students at SMP Dharma Kartini, with the research sample being class VIII-A as the control group and class VIII-B as the experimental group, each consisting of 35 students. The instruments and learning tools used include pretest and posttest questions, as well as LKPD containing material on flat-sided space and the stages of the PBL model. The obtained data will be processed using statistical tests through a two-sample independent t-test, preceded by a normality test and followed by the Mann-Whitney test. The results of the study interpret that there is a difference in the achievement of students' mathematical representation abilities after the PBL model is applied to the flat-sided space material.

Abstract

This study aims to observe the process of students' critical mathematic alabilities in the context of their initial mathematical knowledge. The research utilized a qualitative approach with a descriptive method. The research was conducted at SMP Negeri 7 Cimahi with a sample of 34 students from class VIII-E. The results show that students with good initial mathematical abilities demonstrate better critical thinking skills compared to students with lower initial abilities. High-category students are able to provide detailed answers, supported by appropriate evidence and conclusions, despite minor errors. Medium-category students can answer correctly and provide sufficient reasons and evidence, although sometimes imprecise. Low-category students can provide correct answers but lack supporting evidence and reasons. These findings indicate a positive correlation between initial mathematical abilities and critical mathematical thinking skills. Therefore, improving students' critical mathematical thinking skills requires efforts to enhance their initial mathematical abilities through adaptive and effective teaching methods.

Abstract

This study seeks to investigate the mathematical connectivity of students with field-dependent (FD) and field-independent (FI) cognitive styles in the context of solving Pythagorean puzzles. The research participants were two students from MTs Al Hidayah Karang Ploso, who had studied the Pythagorean theorem. Research data were acquired via interviews, cognitive style assessments, and the examination of mathematical connectivity skills. The veracity of the data was assessed through triangulation following the presentation and analysis of the summarized data. The instruments employed comprise the Group Embedded Figure Test for evaluating cognitive style and a mathematical connection ability assessment featuring three Pythagorean problems. The results indicated that the S-FI cognitive style effectively linked mathematical principles to real-world difficulties and situations. Conversely, S-FD cognitive type could only establish a restricted connection between mathematical concepts. The superior mathematical connection ability of the S-FI cognitive style compared to the S-FD cognitive style underscores the need of considering cognitive type in mathematics education.

Abstract

The Semiotic process (construction of sign meaning) is very closely related to mathematics which consists of signs or symbols. This research aims to explore students' semiotic processes in constructing the meaning of symbols in whole numbers. This research is a qualitative descriptive research using a semiotic approach. The subjects in this research were selected using purposive sampling (purposeful sampling). The subjects in this research were 32 elementary school students. Based on this research, 5 types of semiotic construction patterns were obtained with each subject grouped based on its semiotic construction, namely 1) strong semiotic construction, 2) weak semiosis construction, 3) True-False semiotic construction, 4) False-True semiotic construction, and 5) False-False semiotic construction. The semiosis construction process is a determining factor in students understanding the signs of operations in integers.
