AbstrakTeori bilangan merupakan cabang matematika yang mempelajari sifat-sifat dan hubungan dari suatu bilangan bulat. Untuk dapat memahami materi teori bilangan dengan baik maka dibutuhkan kemampuan pemecahan masalah yang baik pula. Penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah matematika mahasiswa pada mata kuliah teori bilangan. Subjek penelitian yaitu 26 mahasiswa program studi pendidikan matematika, FKIP, Universitas Suryakancana tingkat I tahun ajaran 2017-2018. Data penelitian yang dikaji adalah lembar jawaban mahasiswa pada Ujian Tengah Semester tahun ajaran 2017-2018. Dengan metode deskriptif kuantitatif, didapatkan hasil secara umum yang menerangkan bahwa kemampuan pemecahan masalah mahasiswa program studi pendidikan matematika FKIP Universitas Suryakancana dapat dikategorikan “cukup” (64,62%). Lebih rinci, kemampuan mahasiswa dalam merencanakan penyelesaian masalah dapat dikategorikan “baik”, dengan persentase 74,62% namun sayangnya kemampuan dalam melakukan pengecekan kembali adalah yang paling lemah, dapat dikategorikan “kurang” dengan persentase 54,62%. Hal ini yang nantinya akan menjadi dasar evaluasi dalam perbaikan pembelajaran. College Students’ Problem-Solving Skills Analysis on Number Theory CourseAbstractNumber theory is a branch of mathematics that studies the properties and relationships between an integer.

Problem solving is a basic skill that should be possessed by students. Mathematical problem solving abilities play a role in solving every problem both other subjects and problems in everyday life. Through mathematical problem solving activities students are directed to build mathematical knowledge, think logically, systematically and measurably. The fact is that students' mathematical problem solving abilities are still low. The learning process that focuses on exercises that provide opportunities for students to develop mathematical problem solving skills to become a model for improvement in the learning process. The Missouri Mathematical Project learning model is an appropriate learning model to facilitate students in developing their thinking in solving mathematical problem solving problems. For this reason, this study aims to improve students' mathematical problem solving abilities through the application of the Missouri mathematical learning model. This type of research is a classroom action research (PTK). The research subjects were grade V students of MIS Al Firdausy Pematang Reba. The data collection technique used was a mathematical problem-solving ability test. The data analysis technique used is quantitative data analysis. Based on the results of the test of mathematical problem solving abilities, there was an increase in each cycle starting from the initial pre-action test, cycle I and cycle II. It can be concluded that there is an increase in students' mathematical problem solving abilities through the application of the Missouri mathematical learning model.

The purpose of this research was to find out how the stage of proofing the Stewart theorem was conducted by students of the Mathematics Education Department at Catholic Widya Mandala University of Madiun. This type of research is qualitative research with descriptive data analysis. The number of research subjects consisted of three students. This study describes the stage of proofing Stewart's theorem by students. The data collection process begins with the subject being asked to prove Stewart's theorem and write down the process of proving Stewart's theorem on the answer sheet provided. From the results of data collection, it was found that the verification process carried out by the three students used the direct verification method, there were some similarities between the three students in initiating the verification process, namely: drawing a high line on a triangle and using the pythagoras theorem to add information used in the verification process, to proving that Stewart's theorem required precision when describing an algebraic form and understanding of algebraic concepts from numbers, to prove Stewart's theorem needed time according to the speed of thinking that proves, to prove the Stewart theorem required problem solving skills, logical thinking, critical, analytical and systematic. Thus it can be concluded that, in general the steps of proving Stewart's theorem carried out by students of the Mathematics Education Department, starting with drawing ABC triangles and also describing auxiliary lines (high of CE), collecting information used in the verification process, then use the information obtained to describe the shape of the right side of the equation  becomes the left hand side, so that the equation applies.

Students Attitudes

This study aims to identify the attitudes of students on the ability to solve problems with mathematics. The attitudes of students evaluated in this study include self-confidence, anxiety, enthusiasm, and self-regulated mathematics learning. The research subjects were 79 students in grade VIII. The researcher re-concentrated on three students from all of them, who had mathematical problem-solving skills in the high, medium, and low groups. These subjects were selected from students who focused on problem-solving mathematical skills, questionnaires on the attitudes of students, and interviews with researchers. The instruments used to collect were an instrument of problem-solving mathematical ability and an instrument of students’ attitudes in the form of student attitudes towards mathematics questionnaire. The research method used is descriptive qualitative. The findings have shown that the majority of students are balanced between excited and unexcited on mathematics. The majority reason for students who are enthusiastic about mathematics is that they can improve their abilities, talents, and knowledge. Others have different explanations such as having the resources; formulas and problems, making them feel challenged; thinking that mathematics is important. The majority of students had a low category of self-confidence and anxiety towards mathematics, and had a moderate level of enthusiasm in mathematics and self-regulated learning.
