Keluarga memiliki kontribusi terhadap perkembangan calon mahasiswa khususnya saat memilih jurusan di sebuah perguruan tinggi. Memilih jurusan di sebuah peguruan tinggi bagi setiap calon mahasiswa tidak dapat dipisahkan dari dukungan keluarga. Banyak calon mahasiswa di indonesia ketika memilih jurusan masih dipengaruhi dukungan keluarga saat mengambil sebuah keputusan, hal ini tidak terlepas dari peran keluarga khususnya orangtua sebagai pendidik pertama dan utama dalam kehidupan anaknya terutama ketika seorang anak akan memutuskan suatu hal yang berkenaan dengan pendidikan dan karir nya di masa depan. Penelitian ini bertujuan medeskripsikan faktor dukungan keluarga dalam mempengaruhi minat mahasiswa memilih jurusan pendidikan matematika. Penelitian ini dilaksanakan di IAIN Padangsidimpuan dan partisipan penelitian merupakan 43 mahasiswa program studi tadris/pendidikan matematika di IAIN Padangsidimpuan. Penelitian ini menggunakan pendekatan kuantitatif dan kualitatif dengan jenis penelitian deskriptif dan teknik analisis persentase. Hasil analisis faktor dukungan keluarga dibagi menjadi lima kategori dalam mempengaruhi minat mahasiswa memilih jurusan pendidikan matematika yaitu: a) berpengaruh sangat tinggi 5%, b) berpengaruh tinggi 23%, c) berpengaruh sedang 49%, d) berpengaruh rendah 16%, dan e) berpengaruh sangat rendah 7%.

Mathematics is part from a human activity; it cannot be separated from daily human life, both in theory and in practice. Problem solving is the most important topic in learning Mathematics. However, problem solving is a complex process that has many components. One of them is the difficulty of students in answering the questions about how to find the area of polygon. Students are hard to find out two or more shapes contained in polygon. The students are hard to find unknown measurements, because they do not understand the questions. Therefore, teachers should give guidance to the students in order to help them to solve problems correctly. The purpose of this study was to analyze students’ difficulties to solve the problems of the polygon area questions for the fourth grade of one state elementary in Padang Sidimpuan City. There were 33 participants consisting of 16 male and 17 female students. The students were given a problem solving test and the questions were related to a wide area of polygon consisting of five questions. The findings of the study indicated that students were hard to find solutions to solve mathematical problems of the polygon area flat shapes in class, suggesting that teachers should strive to develop students’ critical thinking as well as creative thinking so they will have a good problem solving skills.

The purpose of this research was to describe the students’ error in measurement materials in terms of learning style. This is a qualitative descriptive research. The subject of this research was 6 students with each of the two students in visual learning styles, auditory learning styles, and kinesthetic learning style. The research instruments were questionnaire, test, interview, and observations. Data analysis activities were data reduction, data display, and conclusion drawing/ verification. The technique of data analysis used interactive techniques with these three procedures. The result of this research showed that the students’ error with visual learning styles in solving units, size, and time included material concepts errors and the use of mathematical unit; this is because teachers tend to use the lecture method in learning. The students’ errors with auditory learning style in solving unit, size and time included in interpreting data, determining formulas and errors in counting. The cause of this error is not remembering the concept and hurrying in solving math problems. The students’ error with kinesthetic styles in solving unit, size and time included student errors identifying elements and language interpretation, errors in language use, and conceptual errorst.

The background of the problem in this study is that many students are confused and do not understand how to operate integers in a positive form with positive, positive with negative, negative with positive, and negative with negative. The formulation of this research problem is how to learn integer operations in 1st grade class (VII-2), how students behave in learning integer operations in 1st grade class (VII-2), and how student learning outcomes in learning integer operations in 1st grade class (VII-2). The purpose of this study was to find out integer operating learning in 1st grade class VII-2, to find out the attitudes of students in learning integer operations in 1st grade class (VII-2), and to find out student learning outcomes in integer operating learning in 1st grade class (VII-2) MTs.S NU Paringgonan Ulu Barumun Sub-district. This research is descriptive qualitative research, namely research intended to investigate the circumstances, conditions or other things that have been mentioned, the results of which are presented in the form of research reports. The data needed are observation, interviews, and documentation. The results of this study are (1) Learning integer operations in 1st grade class (VII-2) that the mathematics teacher in 1st grade class (VII-2) describes integer operations by carrying out preliminary activities, core activities, and closing activities. (2) The attitude of students in learning integer operations in 1st grade class (VII-2) is not good, like many students who pay less attention and respect for the teacher during the learning process. (3) Student learning outcomes reach a value of 50 - 80, namely 30 students who do not complete or 88% and 4 students who complete or 12% with the results of the average value is 60, which is not good.
