<![CDATA[An appropriate learning method can improve students’ learning achievement. The cooperative learning method encourages students to improve their mathematics learning achievement. Mathematics learning achievement is one indicator of achieving learning objectives. Mathematics is an important lesson to be learned and must be mastered by students. The purpose of this research was to analyze the effect size of the relationship between Cooperative learning method and mathematics learning achievement through meta-analysis quantitative research approach. In this research, the cooperative learning method serves as an independent variable, and mathematics learning achievement serves as the dependent variable. The data was obtained from the online database search results on Google Scholar in 2010-2020. The sample used was 16 research publications that have met the specified criteria. The data analysis technique used was the meta-analysis quantitative approach with correlation meta-analysis. The results showed that there was a positive and significant relationship (level of 5%) between the cooperative learning method and students’ mathematics learning achievement. The average effect size value was 0.15 in the range of 0.04 to 0.27 which was included in the low category. These results have proven the consistency of the findings of previous research. ]]>

<![CDATA[Students' low creative thinking skills and difficulty in drawing graphs from the given algebraic equations are the background of this study. The purpose of this study was to determine the mathematical creative thinking abilities between Android-based GeoGebra and ordinary learning. This study also investigated students’ responses to the application of Android-based GeoGebra. The research method used was quasi-experimental with a nonequivalent group pretest-posttest design. The instruments were a creative thinking test and a questionnaire. The subjects of this study were students of one of the junior high school in Cianjur selected by purposive sampling technique. The studied material was the quadratic equations as a part of algebra. The gain index data analysis technique used was the normality test and the Mann Whitney test while the questionnaire data responses were analyzed through the average percentage of students’ answers. As a result, the students' mathematical creative thinking ability with Android-based GeoGebra was better than ordinary learning. Also, the students provided positive responses to the application of Android-based GeoGebra.]]>

<![CDATA[ICT advancement can be utilized to improve the quality of education. In this globalization era, the millennial generation is demanded to be technology literate and fluent in English to compete in the global world considering that English has been established as an international language. Therefore, the integration of English into learning in the form of multimedia bilingual learning is needed. This study aimed to determine the feasibility, attractiveness, and effectiveness of bilingual learning multimedia on the integral application material for vocational schools. This research is research and development. Based on the results of validation and field trials, the developed bilingual mathematics learning media was in the feasible, interesting, and effective categories. The feasibility of the bilingual learning multimedia based on the material expert validation obtained an average of 4.6 and the media expert validation obtained an average of 4.9 which indicated that the developed product was in the feasible category. The attractiveness of bilingual mathematics learning multimedia based on students’ responses was 89% in the very interesting category. The effectiveness of the developed bilingual learning multimedia to improve students' mathematics learning outcomes was known based on the N-Gain value of 0.8 in the high category. ]]>

<![CDATA[Students often experience difficulties and errors in solving quadratic inequality problems. These difficulties and errors are not only caused by students’ ignorance or misconceptions, but also caused by epistemological obstacles. This study aimed to determine the epistemological obstacles faced by the junior high school students in quadratic inequality. This research was a qualitative research that involved 105 ninth-grade students at one of the junior high schools in Bandung, Indonesia. The data were collected through open-ended tasks and task-based interviews. The data were analyzed using the inductive coding process to classify students’ errors. The descriptive analysis was carried out to reveal students’ ways of understanding and ways of thinking behind each error to be compared with historical analysis. Based on the description of ways of understanding and ways of thinking and comparison with this historical phenomenon, the epistemological obstacles had be confirmed. The results showed that there were epistemological obstacles in quadratic inequalities. The epistemological obstacles consisted of students' quadratic equation knowledge acts and students' arithmetic knowledge acts. However, no epistemological obstacles were found in the development history of quadratic inequality. Students' epistemological obstacles were parallel to the historical phenomena of quadratic inequality. ]]>

<![CDATA[A radical class of rings is called a supernilpotent radicals if it is hereditary and it contains the class for some positive integer In this paper, we start by exploring the concept of Tychonoff space to build a supernilpotent radical. Let be a Tychonoff space that does not contain any isolated point. The set of all continuous real-valued functions defined on is a prime essential ring. Finally, we can show that the class of rings is a supernilpotent radical class containing the matrix ring . ]]>

<![CDATA[This study aimed to describe students' statistical literacy skills based on their reflective-impulsive cognitive style. This study employed descriptive exploratory research with the qualitative approach. The data collecting techniques used were tests, interviews, and field notes. The data analysis techniques employed were data reduction, data presentation, and drawing conclusions. This study discovered that students’ reflective and impulsive cognitive styles influence their statistical literacy skills such as the ability to construct or interpret information or statistical data, understand statistical concepts, and represent the statistical data in a different form. Students with the reflective cognitive style were different from students with the impulsive cognitive style on statistical literacy skills, especially in evaluating statistical information or arguments. Students with the reflective cognitive style tended to be more critical in evaluating statistical information or arguments by providing arguments based on the results of analytical calculations. Students with the impulsive cognitive style used analytical processes in drawing statistical conclusions. Students with the impulsive cognitive style lacked cognitive maturity and tended to use processes holistically rather than analytically in drawing statistical conclusions.]]>

<![CDATA[Mathematical creative thinking ability and self-efficacy are a combination of abilities students need to have when studying mathematics. Mathematical learning is expected to improve both abilities. However, teachers still use conventional learning such as direct teaching, which results in a low increase in students' mathematical creative thinking abilities and self-efficacy. So we need alternative student-centred learning and teachers as facilitators who provide scaffolding. The study was conducted to obtain a description of the discovery learning process with scaffolding which aims to improve the ability to think creatively and self-efficacy. Two quasi-experimental designs with three class groups were used: The Matching-only Pretest-posttest Control Group Design was used to measure mathematical creative thinking skills, and The Matching-only Posttest-only Control Group Design was used to measure the self-efficacy scale. Based on the results of one-way ANOVA, the mathematical creative thinking ability of students discovery learning with scaffolding is better than discovery learning and conventional learning. Likewise, this happens to 'self-efficacy, based on the one-way ANOVA that students' self-efficacy of discovery learning with scaffolding is better than discovery learning and conventional learning. The learning process of discovery learning with scaffolding has a positive impact on the improvement of mathematical creative thinking abilities and self-efficacy]]>
