Abstract

This research is motivated by the importance of mathematical representation ability in mixed fraction material. This study aims to describe the mathematical representation ability of fourth grade students in mixed fraction material based on gender. The research used quantitative method. The sample in this study were fourth grade students with a total of 34 students consisting of 16 male students and 18 female students. Selection of research subjects based on purposive sampling. Data were obtained through tests conducted twice, namely pretest then given treatment (treatment) and posttest with validated test instruments to see students' mathematical representation skills which were then processed and analyzed to draw conclusions and teacher questionnaires to see teacher perceptions about this research. The results showed that the average value of students' mathematical representation ability in visual representation reached 65.2%, representation of mathematical equations or expressions reached 43.5% and representation of words or written text reached 41.2%. Based on gender, male students reached an average of 0.61 and female students reached 0.44. The results of this study indicate that the mathematical representation ability of mixed fractions of male students is faster to accept the material because male students pay more attention to the material when learning so that they understand more quickly while female students play more.

Abstract

The background of this research highlights that students often struggle to understand the place value of numbers, as each digit in a number represents a value based on its position. This challenge arises because the learning process lacks the use of engaging media and relies heavily on one-way interactions. To address this issue, a teaching approach that incorporates media and promotes active student involvement is required. This research implements the STAD-type cooperative learning model assisted by a stick box to enhance students' understanding of place value concepts. The study employs a quasi-experimental nonequivalent control group design method, with fifth-grade students from public elementary schools in North Sumedang District as the population. The primary research instrument is an essay test designed to measure conceptual understanding, supplemented by non-test instruments such as observations and questionnaires to collect additional data. The findings indicate that the STAD-type cooperative learning model assisted by a stick box significantly improves students' understanding of the place value concept, with a gain score of 0.746 categorized as high. In contrast, the conventional learning model resulted in a gain score of 0.178, categorized as low. Thus, it can be concluded that there is a significant difference in conceptual understanding of place value between students who learn using the STAD-type cooperative model with stick box assistance and those who engage in conventional learning methods.

Abstract

This research is motivated by the low mathematical conceptual understanding of fifth-grade students regarding data collection and presentation. The conventional, teacher-centered learning process is considered ineffective in fostering deep understanding. This study aims to determine the difference in the effect of the Problem-Based Learning (PBL) model and conventional learning on students' conceptual understanding. This study employed an experimental method with a non-equivalent control group design. The population comprised fifth-grade students in Sumedang Regency. Through purposive sampling, SDN Sindang II (n=31) was selected as the experimental class, and SDN Hariang (n=34) as the control class. The instruments used were tests and observations. Data analysis for the conceptual understanding test was conducted using inferential statistics to draw conclusions. The results showed that the experimental class's average score increased from 54 (pretest) to 67 (posttest) with an average N-Gain of 0.28. Meanwhile, the conventional learning class obtained an average pretest score of 62, increasing to 66 in the posttest, with an average N-Gain of 0.07. It is concluded that there is a significant difference in influence between the Problem-Based Learning model and conventional learning on students' conceptual understanding

Abstract

This research was motivated by the low level of students’ mathematical problem-solving abilities, particularly in the topic of standard units of length. The main objective of this study was to analyze the effect of the STAD learning model on the mathematical problem-solving abilities of third-grade elementary school students. This study employed a quantitative approach with a quasi-experimental design using a non-equivalent control group. The research population consisted of all third-grade students in Paseh District, while the sample included 30 third-grade students from SDN Paseh I as the experimental class and 33 third-grade students from SDN Cileuksa as the control class. Data were collected through mathematical problem-solving ability tests. The findings revealed that the implementation of the STAD model had a positive effect on students’ mathematical problem-solving abilities, as indicated by an average N-Gain score of 0.48 in the experimental class. Meanwhile, conventional learning also produced a positive effect, but with a lower average N-Gain score of 0.20 in the control class. Therefore, it can be concluded that the STAD learning model exerted a more significant effect, as reflected in the higher improvement of mathematical problem-solving abilities in the experimental class compared to conventional learning in the control class.

Abstract

This study was motivated by learning obstacles experienced by fifth-grade elementary students in understanding data representation using bar charts, particularly in determining scales and interpreting data. The study aimed to identify these obstacles and develop a didactical design based on Realistic Mathematics Education (RME) to reduce them. The research employed Didactical Design Research (DDR), consisting of prospective analysis, implementation, and retrospective analysis. Data were collected through diagnostic tests, observations, interviews, and analysis of students’ work. The findings indicate that the learning obstacles were epistemological and didactical in nature. The implementation of the RME-based didactical design improved student engagement and conceptual understanding of data representation, although learning outcomes varied due to differences in prior knowledge. This study recommends further research to apply similar didactical designs to other statistical topics and educational levels to enhance students’ numeracy literacy
