The method used is a mixed method research with a sequential explanatory design. In this research, 6 research subjects were taken based on the level of SRL in class VIII A students of SMP Negeri 1 Tayu, Pati Regency for the academic year 2022/2023. The results showed that (1) the CPS learning model was effective on students' mathematical creative thinking abilities, and (2) research subjects with high SRL categories were able to meet all indicators of mathematical creative thinking ability, namely fluency, flexibility, originality, and elaboration; research subjects with moderate SRL category only met three indicators of mathematical creative thinking ability, namely fluency, originality, and elaboration; research subjects with low SRL category can’t meet all indicators of mathematical creative thinking ability. Recommendations to students with low levels of SRL can’t meet all indicators of mathematical creative thinking ability by giving assignments independently and doing peer teaching.</em></p>2022-12-31T00:00:00+00:00Copyright (c) 2022 De Fermat : Jurnal Pendidikan Matematikahttp://jurnal.pmat.uniba-bpn.ac.id/index.php/DEFERMAT/article/view/284ANALYSIS OF THE THOUGHT PROCESS OF STUDENTS WITH ANXIETY ABOUT HOTS MATH PROBLEMS BASED ON MASON'S WORK PHASE2022-11-10T12:12:41+00:00Suci Wulandarisuci.w@adzkia.ac.idSri Novia Martinsrinovia91@fmipa.unp.ac.idWiddya Rahmalinawiddyarahmalina@adzkia.ac.id<p><em>This research was motivated by the anxiety of students of mathematics education study program towards HOTS mathematics problems. This anxiety affected the quality of their thought processes. Therefore, the purpose of this study was to analyze the thought processes of students with anxiety feeling about HOTS math problems based on Mason's work phases, namely entry, attack, and review. This research was a qualitative descriptive research. The datas in this study were obtained from mathematics anxiety questionnaire, HOTS mathematics test and interviews. Based on the analysis of the data collected, it could be concluded that students with high levels of anxiety fulfill the phase “entry“ only on aspect “want”, the phase “attack” was only in the aspect ”try”, but did not meet the phase “review”. Students with moderate levels of anxiety met the phase “entry” at aspect “know”, “want” and “introduce”, phase “attack” on the aspect “try” and “maybe”, but did not meet the phase “review”. Students with low anxiety levels met the phase “entry” at aspect “know”, “want” and “introduce”, the phase “attack” on the aspects “try”, “maybe” and “introduce”, but also does not meet the phase “review”.</em></p>2022-12-31T00:00:00+00:00Copyright (c) 2022 De Fermat : Jurnal Pendidikan Matematikahttp://jurnal.pmat.uniba-bpn.ac.id/index.php/DEFERMAT/article/view/275THE INFLUENCE OF PERCEPTIONS OF SELF-DISCIPLINE ON STUDENT MATHEMATICS LEARNING OUTCOMES2022-08-01T10:55:55+00:00Besse Intan Permatasaribesse.intan@uniba-bpn.ac.idTri Hariyati Nur Indah Saritri.hariyati.nis@uniba-bpn.ac.id<p><em>The purpose of this study was to determine whether the perception of self-discipline has an influence on students' mathematics learning outcomes. This is cross sectional survey research with quantitative approach. The research sample was randomly selected from the population (N = 64) and 55 students were chosen based on the Isaac & Michael table. Questionnaires were used to collect data on perception of self-discipline and passed the validity test and reliability test (Cronbach's Alpha coefficient = 0.71; considered as high reliability). Whereas, the data of mathematics learning outcomes were obtained from daily mathematics exams. Simple linear regression statistical analysis was used to proceed the data and the result showed that 7 students had perception of self-discipline in low category, 35 students in medium category, and 13 students in high category. Also, the perception of self-discipline has a positive linear relationship with mathematics learning outcomes and contributes 31.8% of the variance of mathematics learning outcomes (R = 0.564; R2 = 0.318; </em>β<sub>1</sub><em> = 1.679; p < 0.05).

Learning is done by utilizing digital-based learning applications that can have a fun effect on students. Learning media that are often used in digital-based learning processes usually use the Kahoot! and Quizizz platforms. The purpose of writing this article is to explain the role of educational games Kahoot! and Quizizz in supporting mathematics learning which can later be used by teachers in the classroom learning so that learning is more varied, less boring, and more fun for students. The writing of this article uses a literature study method by reviewing journals related to Kahoot! and Quizizz. The results of the study show that there are several benefits of using Kahoot! and Quizizz, namely: increasing student learning outcomes, accelerating understanding of the material, increasing students' motivation and independence, increasing thinking and learning abilities, students having a positive attitude in learning, students being more active in learning, learning is more fun and less boring and increases interest in learning.</em></p> <p><em> </em></p> <p> </p>2022-12-31T00:00:00+00:00Copyright (c) 2022 De Fermat : Jurnal Pendidikan Matematikahttp://jurnal.pmat.uniba-bpn.ac.id/index.php/DEFERMAT/article/view/84DEVELOPMENT OF SOCIAL ARITHMETIC TEACHING MATERIALS TO IMPROVE UNDERSTANDING OF MATHEMATICAL CONCEPTS OF JUNIOR HIGH SCHOOL STUDENTS2020-08-12T00:43:30+00:00Pujia Siti Balkistpujiabalkist@ummi.ac.idHamidah Suryani Lukmanhamidahsuryani@ummi.ac.idNita Andrianinitaandriani63@gmail.com<p><em>This study aims to determine the validity of animation-based teaching material of social arithmetic topic animation-based teaching material of social arithmetic to improve students' understanding of mathematical concepts.

Metacognition ability in solving the problem in question is the awareness of thinking by involving the planning process, monitoring/monitoring process and evaluation process at Polya's steps, namely the stages of understanding the problem, planning, completing and re-examination. This study uses a descriptive approach. This research was conducted at SMK Negeri 3 Sukabumi with subjects from class XII Catering 4 consisting of three students as representatives of the high, medium and low problem solving groups. Data collection using test and interview methods. The test instruments used are three explanations of problem solving material limits on algebraic functions. The data analysis process in this study includes data reduction, data presentation and conclusion drawing. Based on the results of data analysis, it was found that the dominant metacognitive ability possessed by high subjects was the process of planning, monitoring and evaluation at the stage of understanding and planning for completion. Meanwhile, the metacognitive abilities of the moderate and low groups were dominantly not seen as complete and fulfilled in every step of problem solving. The metacognition level of the high group students was at the level of strategic use, the middle group students was at the level of aware use and the low group students was at the level of tacit use.</em></p>2022-12-31T00:00:00+00:00Copyright (c) 2022 De Fermat : Jurnal Pendidikan Matematika
