Abstract

Number sense is an essential primary mathematics material in elementary school that students must master. Learning media may be utilized in elementary schools' teaching and learning process to engage and inspire students to participate in learning activities, particularly mathematics. Therefore, the researchers designed an interactive game using Genially to improve students' number sense. The ADDIE development model was applied in the research and development procedure. In this research, the ADDIE development model began by analyzing problems related to the mathematics learning process in elementary schools, analyzing the environment and work situation, designing an interactive game, developing the game based on validation results from three media experts and two concept experts, and conducting a one-on-one trial. The product feasibility was tested on 46 students who were divided into two classes. Class B served as the experimental class, while Class A served as the control class. The interactive game's validation findings showed that the developed interactive learning media was practical and useful. As a result of the implementation, the experimental class students' grasp the material better than the control class.

Abstract

Reviewing lessons as a very important form of learning and very important role to impress students. The research method was adopted the ADDIE model design. This research was done at Balihan Senior High School, China. The population of this research are 43 students and using random sampling to selected a representative 5 students. The student statement result show that, a using Hawgent dynamic in the review lesson can improve student learning performance, very useful in the learning process and etc with statement average is 80.4% or good category. Based on validation results of the 3 aspects obtained an average percentage of 81.33% in a good category. Therefore, the review lesson of basic theorem vector plane using Hawgent dynamic mathematics software can be applied to the teaching process and can using this dynamic software to the review lesson another mathematics topics.

Abstract

Despite the increasing focus on creativity in mathematics education, research on the combined effects of cognitive style and gender on mathematical creative thinking in vocational high schools is still scarce, especially in Indonesia. This study investigated the influence of cognitive style and gender on the mathematics creative thinking of 60 eleventh-grade students in a vocational high school, classified as Field Independent (FI) or Field Dependent (FD) by the Group Embedded Figures Test (GEFT). Mathematical creativity, which includes fluency, flexibility, and originality, was assessed using an open-ended test that was verified by two experts in mathematics education and pilot-tested for reliability. Data were examined via two-way ANOVA. The findings indicated that FI students markedly surpassed their FD counterparts across genders (p < 0.001), although gender disparities were not statistically significant, although females exhibited a tendency for enhanced fluency and inventiveness, while males shown better flexibility. No notable interaction between cognitive style and gender was detected. These findings underscore the superiority of cognitive style over gender in influencing mathematical creativity in vocational environments and present the inaugural empirical evidence for this combination effect within the Indonesian context. They propose that vocational mathematics instruction must be cognitively adaptive providing structured scaffolding and collaborative methods for FD learners, and open-ended, self-directed tasks for FI learners to enhance creativity and problem-solving abilities pertinent to real-world vocational challenges.

Abstract

Student-oriented classroom is the fertile ground for students to develop core literacy of mathematics. The new curriculum standard emphasizes the teaching concept of "student-oriented". In the teaching activities, teachers should give full play to the subject status of students, return the classroom to students, so that students can better show themselves, so that they can master mathematical knowledge and develop the core literacy of mathematics subject naturally. However, at present, the classroom atmosphere of some middle school mathematics students' classroom reform pilot middle schools has not reached the ideal effect. There are some problems in the teaching classroom, such as ignoring students' main position, ignoring students' initiative in learning, and teachers' student-oriented concept is not thorough enough. This paper aims to develop students' core literacy. By studying the current situation of the mathematics students-based classroom in junior middle school and putting forward strategies to solve the problems, the teaching mode of the student-oriented classroom is improved.

Abstract

Mathematical abstraction is the basic idea of mathematics, which is an important foundation for the formation of rational thinking, reflects the essential characteristics of mathematics, and permeates its generation, development, and application. The latest version of the general high school mathematics curriculum standard lists mathematical abstraction as the primary core literacy of the discipline, and mathematical abstraction literacy has become the focus of educational research. A number of scholars have researched mathematical abstraction literacy in senior high schools in China in recent years, but there is no literature that summarizes and compiles this aspect. This paper employs the literature analysis method to review and sort out the relevant literature on mathematical abstraction literacy and draws the following conclusions: (1) Previous research on mathematical abstraction literacy mainly contains five aspects, which are the connotation of mathematical abstraction, the current status quo of the level, the evaluation method, the influencing factors, and the strategies for the cultivation. (2) There are generally more studies on the connotation of mathematical abstraction, the current status of the level, and the cultivation strategy. However, in terms of influencing factors, the views in the existing literature are scattered, and no major influencing factors have been found. (3) The research methods are relatively single, with literature analysis or discursive methods predominating, especially the analysis of the influencing factors is not systematic and objective enough, lacks quantitative research for empirical evidence, and lacks targeted and practical cultivation strategies

Abstract

Evidence-based research on the effect of Realistic Mathematical Education (RME) has been conducted. However, whether differences in the measured variables alter the studies' effect sizes have not been explored. To fill this gap, it is necessary to conduct a meta-analysis study that can summarize the evidence for the effect of RME and analyze how the differences in the measured variables are associated with the effect size (ES) of the study. The research sample is an individual study of the effect of RME on various mathematical abilities identified from the ERIC database, the Scopus database, and Google Scholar. Based on the inclusion requirements, 54 independent samples from 38 individual studies were included in the analysis with a total of 6140 students included. The estimation method uses a random-effect model, and the Comprehensive Meta-Analysis (CMA) software is used as a data processing tool. The results of the analysis showed that the ES of the study was 0.97. This shows that overall, the use of RME has a significant effect on students' mathematical abilities. The moderator analysis results explain that the differences in the measured variables moderate the implementation of RME. These findings contribute to the implementation of RME in classrooms and the further development of RME by considering the categories of abilities being measured.
