Mathematics learning is always related to problems. Computational Thinking is a thought process that is needed in formulating a problem and its solution. Prospective mathematics teachers have the responsibility to equip themselves with various abilities including Computational Thinking which will become their provisions when they become teachers. As a first step to prepare strategies that can be used in improving and developing students 'computational thinking skills, it is necessary to know and first how the students' computational thinking skills. This type of research is descriptive qualitative. The research respondents were 10 students of UNDIKMA mathematics education. Respondent categories are students who have taken Graph courses. The technique of determining respondents is a random sampling method. The research data interview techniques were tests and interviews. The instruments used are two questions to solve math problems. The results shown in solving the first and second questions show that respondents are able to solve problems with the Computational Thinking component. begins with decomposition, abstraction, and algorithms. While the generalization component is not visible in the problem solving process, although there were some respondents who answered incorrectly. This is because the respondents do not understand the questions. Questions are only read once or twice so the information in the questions has not been properly implemented. Even the respondents only saw the simplest paths and ignored the winding paths in solving the second problem.

The low of student learning outcomes in mathematics subjects is caused by a lack of student involvement and the conventional methods used by the teacher. Therefore the need for creativity and mathematical habits of mind to be able to improve learning outcomes. To improve creativity and mathematical habits of mind, learning methods are needed that can stimulate student’s creativity and mathematical habits of mindwith Creative Problem Solving (CPS)models assisted by visual media. The aims of this study was to determine the increase in student’s creativity and mathematical habits of mindby applying CPS models assisted by visual media in grade X MA Al-Kautsar NW RebanBurung Academic Year 2018/2019. This type of research was classroom action research conducted in two cycles. In the first cycle obtained the level of creativity of students was 2.78, and for the percentage of students' mathematical habits of mind was 63.63%, and the percentage of classical completeness was 75%. While in the second cycle there was an increase in the level of student creativity to 3.07, and for the percentage of students mathematical habits of mind increased to 82.25%, the percentage of classical completeness reached 95% and had fulfilled the KKM.

This study aims to describe the ability of students to understand the concept of the Three Variable Linear Equation System (SPLTV) based on the APOS theory (Action, Process, Object and Schema) in students of MA Tarbiyatul Mustafid Batu Rimpang. This type of research is a qualitative descriptive study with 3 students subject taken from MA Tarbiyatul Mustafid Batu Rimpang students with high, medium and low ability categories. The results of the study show that highly capable subjects have an understanding of the stages of action, processes, objects and schemes. Subjects who are capable of having understanding at the stage of action, process, object and at the schematic stage students cannot design and complete the mathematical model they form. While low-ability subjects have an understanding of the stages of action, process, object but have not fully arrived at these stages because the subject made a mistake in the calculation process so that the solution given is wrong. The understanding possessed by students with moderate and low ability is the same at the scheme stage.

Type of this research is experimental research which aims to determine the effect of problem posing learning on mathematical communication of students prospective mathematics teacher at IKIP Mataram by calculus I module. This module developed by a problem posing approach that meets the criteria of being feasible, practical, and effective. The experimental design used was the type of Quasi Experimental Design and the design used was Nonequivalent Control Group Design. Data collection instruments included tests of mathematical communication skills, student response questionnaires, and lecturer response questionnaires. Based on the results of the hypothesis test analysis obtained a value with a significantlevel  or is . So that  it is rejected and accepted. So it can be concluded that Problem Posing Learning by using problem posing based I calculus module influences student mathematics communication and is effectively used in lectures

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran matematika realistik terhadap motivasi dan hasil belajar matematika siswa kelas III SDN 6 Cakranegara Tahun Pelajaran 2021/2022. Penelitian ini merupakan penelitian eksperimen jenis quasi experimental dengan tipe penilitan nonequivalent control group design. Populasi penelitian ini seluruh siswa kelas III SDN 6 Cakranegara dengan tehnik pengambilan sampel yaitu sampel jenuh.Teknik Pengumpulan data dalam penelitian ini adalah menggunakan lembar observasi keterlaksanaan pembelajaran, angket dan tes hasil belajar kognitif (post-test). Data hasil observasi keterlaksanaan pembelajaran menggunakan model matematika realistik dianalisis menggunakan analisis deskriptif, yaitu rata-rata keterlaksanaan pembelajaran yang dilaksanakan selama dua kali pertemuan mencapai 94,4% (Sangat Baik). Data hasil belajar dan angket yang sudah didapatkan kemudian dianalisis dengan menguji hipotesis, diperoleh t hitung motivasi sebesar 411,55 dan t hitung hasil belajar sebesar 5,71 dimana t tabel yaitu 1,676 dan dapat dinyatakan kedua t hitung > dari t tabel. Hal ini menunjukakan bahwa Ho ditolak dan Ha diterima, berarti Hipotesis dalam penelitian ini ada pengaruh model pembelajaran matematika terhadap motivasi dan hasil belajar matematika siswa kelas III SDN 6 Cakranegara tahun ajaran 2021/2022 diterima .
