Abstract

The background of this study is the unsatisfactory motivation of grade II students to learn mathematics, especially in addition and subtraction lessons. The use of dull and ineffective learning techniques contributes to students' low learning motivation. Therefore, the use of STAD type cooperative learning model is one of the solutions that can be used for second grade elementary school students. This study aims to determine the effect of the STAD type cooperative learning model on grade II students' learning motivation in addition and subtraction in mathematics. The approach used is a quantitative and quasi-experimental method. The population consisted of all SDN Tugu and SDN 1 Kalaparea; the sample consisted of 35 grade II SDN Tugu students as the experimental class and 29 students of grade II SDN 1 Kalaparea as the control class. These learners were selected using a purposive sampling technique. The data collection techniques were tests, questionnaires, observation, and documentation. The techniques used to analyze the data are validity test, reliability test, normality test, homogeneity test, and T-test. Based on the results of the research that has been done, it is concluded that using the STAD type cooperative learning model increases the motivation to learn mathematics in the material of addition and subtraction of standard-length units. This can be seen from the data analysis obtained, where the sig value (2-tailed) of 0.0001 is less than 0.05, meaning that the probability value of sig.

Abstract

By evaluating students’ performance in their mathematical communication skills and characterizing those skills in terms of their mathematical resilience, this study seeks to determine the efficacy of probing-prompting learning. A mixed method by using a sequential explanatory research design is employed. The study was conducted in two phases: first, quantitative data was collected and analyzed, then based on the findings of the quantitative data, qualitative data was collected and analyzed. The results of the research show that (1) the probing-prompting model with performance assessment is effective to improve students' mathematical communication skills and mathematical resilience and (2) based on the analysis of mathematical communication skills regarding students' mathematical resilience, it shows that students who have low stage of mathematical resilience are only able to express one indicator of mathematical communication skills, while students who have moderate and high stages of mathematical resilience are able to express five indicators of mathematical communication ability. The conclusion is probing-prompting learning with performance assessment can be used to improve students' mathematical communication skills and based on students’ mathematical resilience, students also have different levels of mathematical communication skills.

Abstract

Learning using technology can grow students' interest, one of which is augmented reality, which can attract students' interest in learning mathematics. This research explores AR forms and responses to students' interest in learning mathematics after using AR. The research method used is a systematic literature review. For this research, a synthesis of relevant studies was created through the PoP (Publish or Perish) application by searching for articles using Google Scholar. Based on the selection results obtained, 740 articles. Ten duplicate articles were found, 143 articles that did not contain any keywords, 561 articles that did not meet the researcher's criteria, and seven articles that did not answer the researcher's question, resulting in 19 basic studies published between 2013 and 2023. The research results provide information that there are forms of AR that can influence interest. Students learn mathematics, namely AR learning media in AR playing cards, 3-dimensional AR, AR text-to-speech applications, AR building space, learning media with magic books, AR and Flash Card applications, and other Android-based AR applications. Augmented Reality (AR) has a very positive impact on students learning mathematics. Thus, educators may consider additional training in the use of AR technology and develop learning strategies that include elements of AR to support the achievement of student mathematical learning objectives effectively.

Abstract

This research addresses the low critical mathematical thinking abilities of students when facing mathematical problem-solving challenges. The study aims to evaluate the impact of implementing various teaching approaches, including Contextual Teaching and Learning (CTL), Problem-Based Learning (PBL), and Direct Instruction (DI) models, on students' critical mathematical thinking abilities. Participants included 276 eighth-grade students from SMP La Tansa Mashiro 1, 2, and 3 in Lebak Banten during the academic year 2022/2023, divided into three classes. Samples were selected using simple random sampling, resulting in 94 students for CTL, 92 students for PBL, and 90 students for DI instructional models. Data collection involved self-efficacy questionnaires and critical mathematical thinking ability tests, analyzed using a two-way ANOVA. The findings suggest that implementing CTL and PBL models positively influences students' critical mathematical thinking abilities. Additionally, students' self-efficacy levels contribute significantly to their critical mathematical thinking abilities. Furthermore, a significant interaction was observed between the implementation of CTL, PBL, and DI models and students' efficacy levels, collectively influencing students' critical mathematical thinking abilities. These results emphasize the importance of employing active approaches, such as contextual, problem-based, and direct instructional methods, while also enhancing students' self-confidence to improve their critical mathematical thinking abilities. It is hoped that implementing these recommendations will enhance the effectiveness of mathematics learning and foster the development of students' critical thinking skills.
