Pembelajaran yang dilakukan di perguruan tinggi menuntut mahasiswa memiliki kemampuan mengatur serta mengendalikan proses belajar secara mandiri. Telah banyak studi terkait self-regulated learning mendapatkan perhatian yang signifikan karena potensinya dalam mempengaruhi prestasi akademik mahasiswa, namun belum banyak penelitian yang memfokuskan self-regulated learning pada tingkat akademik. Penelitian ini bertujuan untuk mengetahui perbedaan self-regulated learning mahasiswa pendidikan matematika Universitas Muhammadiyah Prof DR HAMKA berdasarkan tingkat akademik. Sampel penelitian terdiri dari 71 mahasiswa yang terdiri dari berbagai tingkatan akademik. Self-regulated learning diukur menggunakan kuesioner dengan indikator personal function, behaviour function, dan environment function. Temuan penelitian yang didapat yaitu tidak terdapat perbedaan self-regulated learning mahasiswa pendidikan matematika berdasarkan tingkatan akademik. Berdasarkan hasil temuan ini menunjukan bahwa tingkat akademik tidak memberikan pengaruh terhadap self-regulated learning pada mahasiswa pendidikan matematika. Kata kunci: Self-regulated learning, Tingkat Akademik, Mahasiswa Pendidikan matematika Abstract: Learning conducted in higher education requires students to have the ability to organize and control the learning process independently. The concept that refers to a person's ability to organize, supervise, and control learning strategies for effective learning is called self-regulated learning. Many studies related to self-regulated learning have received significant attention because of its potential to affect student academic achievement, but not many studies have focused on self-regulated learning at the academic level. This study aims to determine the differences in self-regulated learning of mathematics education students at Prof DR HAMKA Muhammadiyah University based on academic level. The research sample consisted of 71 students from various academic levels. Self-regulated learning was measured using a questionnaire with indicators of personal function, behavior function, and environment function. The research findings obtained are that there are no differences in self-regulated learning of mathematics education students based on academic level. Based on these findings, it shows that academic level does not influence self-regulated learning in mathematics education students.

Algebraic reasoning skills are important for students to master, with algebraic reasoning students are able to solve everyday problems in algebraic form. Gender is one of the factors that differentiates students' reasoning abilities in solving math problems. This study aims to describe algebraic reasoning in terms of gender differences. This type of research is qualitative with research subjects of four students taken from 31 students, Middle School class VIII by selecting two female students and two male students based on the average score level of each gender in solving System of linear equations of two variables questions based on indicator of algebraic reasoning ability. Data collection techniques in this study were tests, interviews and documentation. The results of this study indicate that the algebraic reasoning of female subjects is higher than that of male subjects. Some of the factors for the low algebraic reasoning of the subject include: the subject is not careful and forgets the formulas that have been taught.

This research aims to determine whether there is a significant relationship between self-efficacy and mathematical problem solving abilities, as well as between learning motivation and mathematical problem solving abilities. Apart from that, this research also aims to find out whether there is a significant relationship between self-efficacy and learning motivation together with the mathematical problem solving abilities of class X students at SMAN 1 Tajurhalang on SPLTV material. This research uses a quantitative approach with correlational methods. The population in this study included all 360 class X students, with a sample of 199 students from six classes. Data collection was carried out through tests to measure mathematical problem solving abilities on SPLTV material, as well as questionnaires that measured students' levels of self-efficacy and learning motivation. The results of the analysis using the Pearson correlation coefficient and multiple correlation show that there is a significant relationship between self-efficacy and mathematical problem solving ability, with a value of r = 0.202 which is classified as a low relationship. Meanwhile, the relationship between learning motivation and mathematical problem solving ability obtained a value of r = 0.194, which is in the very low category. Further analysis also shows that together, self-efficacy and learning motivation have a significant relationship with mathematical problem solving abilities, with a value of r = 0.211 which is in the low relationship strength category.

Social connection requires each individual to have a strong understanding of the environment. Concept understanding can be improved through software. The goal of this research is to predict the effect of mathematics learning using Cabri 3D software. The dependent variable is the mathematics concept of understanding ability. The independent variable is the dummy variable that determines the type of the class. The value of the dummy variable for the class that applied the Problem-based Learning (PBL) assisted by Cabri 3D is 1 and the value of the dummy variable for class without Cabri 3D is 0. Students' mathematics ability was measured by a percentage or probability. The values of the mathematical concept understanding obtained by students were converted into probability values. After the data has been collected, probit regression analysis was used to see the probability of success of mathematical concepts understanding of those who were taught using PBL and those who were taught without using PBL without Cabri 3D. The results of data analysis showed that the types of classes significantly affect the mathematical concept of understanding ability. Thus, it can be concluded that learning with Cabri 3D can improve the mathematical concept of understanding ability.

Computational thinking ability is the ability to solve complex problems with algorithmic solutions based on computational aspects. Self efficacy is a belief in one's own abilities. The subjects in this study are class VIII-H students at SMPN 226 Jakarta as many as 34 students who will then be selected 3 students based on the categorization of self efficacy questionnaire (high, medium, and low) to be interviewed. A qualitative approach with a descriptive form was used with the aim of describing the ability of mathematical computational thinking in terms of self efficacy in class VIII students at SMPN 226 Jakarta. Data were collected from questionnaires, written description tests, and interview guidelines, then analyzed through data reduction, data presentation and conclusion drawing. The results showed that students in the high self efficacy category met four indicators, namely, decomposition, pattern recognition, abstraction, and algorithmic thinking. Students with moderate self efficacy fulfill three indicators, namely, decomposition, pattern recognition, and abstraction. Meanwhile, students with low self efficacy fulfill two indicators namely, decomposition, and pattern recognition. In addition, the results of this study indicate that the better the self efficacy in students, the better the mathematical computational thinking ability.
