Abstract

This research aims to determine the increase in mathematical understanding abilities in class II elementary school students through a problem based learning model assisted by articulate storyline media. The research method used is quasi-experimental research with a pre-test and post-test one group design research design. The research was aimed at class II students at SDN 066 Halimun, Bandung City. The population in this study was all class II students at SDN 066 Halimun. The research sample taken was class II-C as many as 20 people. The data collection techniques used in this research are mathematical ability description tests, observation and documentation. Researchers carried out data analysis by testing hypotheses using SPSS Statistics 26.0 for windows software. Based on the research results, an overview of the learning process using Articulate Storyline media with the problem based learning model is going well. From the results of the hypothesis test, it was concluded that there was a significant difference between the ability to understand mathematical concepts before and after using the problem based learning model assisted by articulate storyline media. There is an increase in students' mathematical understanding ability from the results of the normalized gain test, namely 0.45 with a moderate improvement category.

Abstract

This research aims to determine the increase in the ability to understand mathematical concepts in grade III elementary school students through the Team Games Tournament (TGT) learning model assisted by the PhET application and conventional learning models. The method used is a quasi-experimental design and a nonequivalent control group design. Participants in this research were 63 grade III elementary school students. Sampling in this study used a purposive sampling technique. Data collection techniques in this research are tests, observation, interviews, and documentation. The instrument used consists of a test of the ability to understand mathematical concepts in the form of a description and is stated to have met the requirements for content validity, construct validity, reliability, level of difficulty, and differentiation. The data analysis technique for hypothesis testing uses IBM SPSS Statistics 2.6 software, namely the normalized n-gain hypothesis test. Based on the research results, students' ability to understand mathematical concepts at SDN Pancasila Lembang experienced a significant increase after receiving learning using the Team Games Tournament (TGT) learning model assisted by the PhET application. This is proven by the results of the n-gain data test calculation, which is 0.36 in the medium category. The average posttest score obtained for the experimental class was 67.78 and the average posttest score obtained for the control class was 30.32. This means that the increase in understanding of mathematical concepts in the experimental class is higher compared to the control class. Therefore, it can be concluded that the Team Games Tournament (TGT) learning model assisted by the PhET application is recommended as an alternative learning model for improving students' ability to understand mathematical concepts in elementary school.

Abstract

This research aims to find learning obstacles students experienced during natural number multiplication lessons in third-grade elementary school. Learning obstacles were obtained from the Respondent Ability Test (RAT) analysis on students who had studied the lessons on multiplication of natural numbers. The method used in this research is a qualitative descriptive method. The subjects were respondents who participated in RAT, namely 22 third-grade elementary school students in Bandung, Indonesia. Data collection techniques use tests, interviews, and documentation. Data analysis techniques include data collection, reduction, display, and conclusion. Learning obstacles found in natural number multiplication lessons are categorized into three types, namely ontogenic, epistemological, and didactical obstacles. Ontogenic obstacles occur when there is a gap in the students' thinking when analyzing concrete to abstract concepts. Epistemological obstacles may occur if students need help to apply the concepts they have learned in the context of story problems. Didactical obstacles happen when the learning carried out by teachers is only procedural, so students only memorize each multiplication result. Therefore, it is essential to analyze these learning obstacles and find the causes as a reference in finding solutions to design future learning tools that prevent these learning obstacles from happening.

Abstract

This research is motivated by students' limited ability to understand mathematical concepts, the lack of diverse instructional media, the predominance of conventional teaching methods, and students' diminished motivation and interest in mathematics, particularly in solving word problems. This research aims to explore the learning process, student achievements, improvements, and the impact of implementing the Team Games Tournament (TGT) teaching approach supported with the PhET application on students' understanding of mathematical concepts in mathematics. A quasi-experimental method was employed with a nonequivalent control group design. Data collection methods included pretests (before instruction) and posttests (after instruction). Data analysis was carried out using normality, homogeneity, and hypothesis testing through t-tests and the Mann-Whitney U test. The findings reveal that the learning process when using the TGT teaching approach supported by the PhET application proceeded effectively. From the hypothesis testing results, analysis revealed a meaningful difference between the pre-test scores of the control and experimental classes, together with a substantial difference in post-test scores. This demonstrates that students' ability to comprehend mathematical concepts improved both before and after using the TGT teaching approach with PhET assistance. An effect size test showed a result that falls within the large category. Hence, the application of the TGT teaching approach, supported by the PhET application, positively influences students' ability to understand mathematical concepts.
