Most individuals do not understand creative mathematical thinking only as a cognitive factor, whereas creative mathematical thinking plays a role in affective factors. Self-regulated learning is considered an affective factor that influences mathematical creative thinking skill. The purpose of this study determines the effect of SRL on mathematical creative thinking skill and analyzes in detail the components of SRL at each level of creative mathematical thinking. This study uses an explanatory sequential combination research design. The study population was high school students at SMAN 3 Klaten. The sampling technique used in this study is simple random sampling. The research sample measured mathematical creative thinking ability ( Y ) as a dependent variable, and SRL consists of three components, namely metacognition ( X1 ), motivation ( X2 ), and behavioristic ( X3 ). At the same time, the research subject selection technique is purposive sampling. The researcher chose to divide students' mathematical creative thinking skills into three levels: high, medium, low, where in each level was selected three research subjects. SRL has a positive effect on the ability to think mathematically creative by 85.4%. Metacognitive has the strongest influence on mathematical creative thinking skills. The SRL component has a role in every aspect of creative mathematical thinking consisting of fluency, flexibility, elaboration, and originality. Therefore, for improving mathematical creative thinking skills, students should be given learning based on SRL.

ASPIRE model is an innovation in mathematics learning that is expected to develop mathematical creative thinking ability. The aspects of the ASPIRE model consists of analysis, scaffolding, project, investigation, reaction and evaluation. The research aims to describe the steps of the ASPIRE model. analysis is the stage where students are analyzed their abilities through filling out questionnaires or online tests so the teacher understands the ability of students and gives them treatment according to their abilities. Scaffolding stage is the provision of assistance, motivation, and direction to students in conducting learning activities. Project stage is implementing learning material in a project assignment. Investigation stage is the process of investigating the results of project tasks and communicating them so that they can be compared with the acquisition of others. Reaction stage is applying of problems related to the material in project task. Evaluation is the stage of testing the ability of students individually. The ASPIRE model is a combination of project-based learning models, problem-based learning, and investigative learning that all three learning models are considered capable of developing mathematical creative thinking ability.

The purpose of this study was to analyze the mathematical creative thinking ability test instrument in open-ended problems with ethnomathematic nuances. The aspects that must be possessed in a mathematical creative thinking ability test instrument consist of: fluency, flexibility, originality, and elaboration. These four aspects are contained in open-ended questions. Open-ended questions are questions that can be worked on with several answers or various settlement strategies. Ethnomatematics applied to open-ended questions is batik. Batik that has various styles should be able to explore the mathematical creative thinking ability. The method used to collect data on mathematical creative thinking ability is the essay test method which consists of 5 items. The data analysis technique used is qualitative and quantitative data analysis. Qualitative analysis was carried out by examining the validity of the content. Meanwhile, the quantitative analysis was carried out by using the classical test theory approach which the calculations were assisted by the Microsift Excell program.

Tujuan dari penelitian ini adalah untuk menganalisis pencapaian kemampuan pemecahan masalah matematis pada Pembelajaran Preprospec Berbantuan TIK. Metode kuantitatif adalah metode yang digunakan dalam penelitian ini. Adapun sampelnya diambil secara acak dari seluruh mahasiswa Program Studi Pendidikan Matematika Jurusan Matematika pada salah satu perguruan tinggi negeri di Semarang yang mengambil mata kuliah Kalkulus Integral. Hasil penelitian ini adalah (1) Pencapaian kemampuan pemecahan masalah matematis mahasiswa yang mendapatkan Pembelajaran Preprospec Berbantuan TIK secara keseluruhan dan untuk jenis kemampuan awal matematis sedang lebih baik daripada mahasiswa yang mendapatkan pembelajaran konvensional; (2) Pencapaian kemampuan pemecahan masalah matematis mahasiswa yang mendapatkan Pembelajaran Preprospec Berbantuan TIK untuk kemampuan awal matematis atas dan bawah setara dengan mahasiswa yang mendapatkan pembelajaran konvensional.
