Penerapan Pembelajaran Matematika Realistik Berbantuan GeoGebra untuk Meningkatkan Kemampuan Komunikasi Matematis Siswa SMP

The research was taken because the fact shows that the mathematical communication skill in Indonesia is weak. Models and approaches which are used in learning process being one of the factors that supports the success of mathematical learning. The purpose of this study is to analyze the mathematical communication skill of students in Junior High School by using Realistic Mathematics Education with GeoGebra. This study used a quasi-experiment method. It was held in a Junior High School in Lembang, Bandung. The result of this study showed that mathematical communication of students who learned mathematics using Realistic Mathematics Education with GeoGebra are better than students who learned mathematics using Realistic Mathematics Education with no GeoGebra. The result also indicated that there are positive responses from students toward Realistic Mathematics Education with GeoGebra

Confirmatory factor analysis sosiomathematics norm among junior high school student

The purpose of this study was to confirm the factors that influence the sociomathematics norm. The method used in this research is the ex post facto. The subjects in this study were seventh-grade junior high school students in the city of Yogyakarta, Indonesia (264 students) taken by cluster random sampling. The instrument used was a sociomathematics norm observation sheet consisting of four factors are (1) the experience of mathematics, (2) the explanation of the mathematics, (3) mathematical differences, (4) mathematical communication. Data analysis using structural equation models with the Confirmatory Factors Analysis. The results showed that the modified path analysis obtained goodness of fit mostly in the fit category, so overall the sample covariance matrix is the same as the estimated covariance matrix

Visual Thinking Skills in Solving Geometry Problems Based on Learning Style: a Grounded Theory Study

This study seeks to determine students' visual thinking skills in solving geometric problems based on learning style inventory. The qualitative approach with the grounded theory research method was used. The research participants consisted of 61 students who were given a learning style inventory questionnaire, and 4 students were selected from each learning style category, namely converger, diverger, assimilator, and accommodator. Data collection techniques included learning style questionnaires and task-based interviews. The findings indicated that assimilator and converger students had good visual thinking skills in solving geometric problems and could explain logically every step they used while accommodator students had problems explaining logically at the planning and implementation stages of problem-solving. Meanwhile, diverger students could visualize the problem only at the stage of understanding the problem. At the next stages, they had difficulty in explaining logically, and the problem-solving process was not appropriate

Bibliometric Analysis of Mathematics Reflective Thinking Based on Scopus Database

Reflective thinking is one of the most crucial abilities in learning mathematics. This study aims to reveal bibliometric analysis, including mapping a general overview and exploring research opportunities on ‘mathematics reflective thinking’, has never been carried out before. The articles were derived from Publish or Perish (PoP) software using the Scopus database. A total of 173 articles were found since the beginning of the study on mathematics reflective thinking published until November 2021. After managing the database, this study classified and visualized it by network, overlay, and density visualizations using VOSviewer software. Overall, this review provides an appropriate reference for further research on the study of 'mathematics reflective thinking’

Democratization and the Diffusion of Shari'a Law: Comparative Insights from Indonesia

The democratization of politics has been accompanied by a rise of Islamic laws in many Muslim-majority countries. Despite a growing interest in the phenomenon, the Islamization of politics in democratizing Muslim-majority countries is rarely understood as a process that unfolds across space and time. Based on an original dataset established during years of field research in Indonesia, this article analyzes the spread of shari’a regulations across the world’s largest Muslim-majority democracy since 1998. The article shows that shari’a regulations in Indonesia diffused unevenly across space and time. Explanations put forward in the literature on the diffusion of morality policies in other countries such as geographic proximity, institutions, intergovernmental relations and economic conditions did not explain the patterns in the diffusion of shari’a regulations in Indonesia well. Instead, shari’a regulations in Indonesia were most likely to spread across jurisdictions where local Islamist groups situated outside the party system had an established presence. In short, the Islamization of politics was highly contingent on local conditions. Future research will need to pay more attention to local Islamist activists and networks situated outside formal politics as potential causes for the diffusion of shari’a law in democratizing Muslim-majority countries
