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 article discusses the significance of numerical literacy in using appropriate models and media in mathematics education. The Systematic Literature Review (SLR) used in this article aims to analyze, identify, review, and interpret research on using models and learning media to improve students' numeracy literacy. This literature review involves three stages based on the PRISMA  (Preferred reporting Items for Systematics Review and Meta-Analyses) flow diagram, namely literature screening with 153 documents, the Eligibility stage resulting in 58 relevant documents, and the Qualification stage producing 42 documents meeting the inclusion criteria. The eligible documents were analyzed using thematic analysis, highlighting main themes related to learning models and instructional media in numeracy literacy based on a review of 36 articles.  The aftereffects of the examination demonstrate how proper models and learning media can upgrade understudies' numeracy proficiency abilities and assist them with applying numerical ideas in regular daily existence. The implementation of numeracy literacy can be done through case examples, problem-solving, and utilization of digital technology. Effective learning models for improving numeracy literacy include project-based learning, problem-based learning, Contextual Teaching Learning (CTL), Realistic Mathematics Education (RME), game-based learning, and Flipped Classroom. Several learning media can include instructional videos, software, cultural innovations, and numeracy literacy modules. These approaches can help students become more active and engaged in mathematics learning.

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.
