Abstract

This study aims to describe the thinking process of junior high school students in solving mathematical problems reviewed based on cognitive style field dependent and field independent. The method used in this research is descriptive qualitative research method, while the method of data retrieval is test and interview. The study conducted on the VII grade students of SMPN 2 Marga Asih.The subjects of the study were 2 students from junior high school consisting of 1 students with cognitive field dependent and 1 student style with an independent cognitive field. The results showed that there were significant differences between the two subjects in processing information, that was the subject of FI understand the problem better when compared with the subject of FD. Because if processing information was not stored properly, it will be very influential in the next step.

Abstract

This research aims to examine the differences in the improvement of mathematical problem-solving abilities of MTs students with an open-ended approach and conventional learning. In this research the researchers applied quasi-experimental method, where the samples in this research are students of class VII MTs in Cianjur district and take the subject of students of MTs Tanwiriyyah class VII I a total of 41 students as experimental class who get the learning treatment using the approach Open-Ended and class VII H totaling 40 students as control class that get conventional learning. In this study the instrument that applied the test instrument of the problem-solving ability of mathematics as much as 4 item. The result of N-Gain data analysis using t` test shows students' mathematical problem-solving ability of the experimental class is better than the control class.

Abstract

The Purpose of descriptive qualitative research to describe the problem-solving ability of student mathematics on the material circle for student class VIII SMP in Karawang. The subject of this study consisted of 6 selected students. Data collection techniques using the test. The result of data analysis showed the students beginning ability were included in the low category, because of only about 59% of students from 6 people who are able to solve mathematical problems in the material of the circle.

Abstract

The purpose of this study is to examine how the improve mathematical communication ability of students in learning using contextual approach. The research method used in this study is a quasi-experimental method, with two different classes taken, where the first class gets the learning with the Contextual Approach and the second class using ordinary learning. The population is all students in one of the islamic junior hight schools in Cimahi city with a sample taken two classes. Both classes were given pretest and early questionnaires to determine their initial ability, then the experimental class was given learning with the contextual approach and the control class was given regular learning, and at the end of both classes were given postes that will on though to use help software SPSS 22 and Minitab 16. Analysis using Product Moment Pearson. The results showed a significan students in learning mathematics.

Abstract

This study was conducted by giving a five description test that has been validated to one of the upper classes. This research was conducted in class VII J SMP NEGRI 1 CILAMAYA WETAN with limited subject ie 6 students with high, medium, and low grade student classification. The results of the research were students' answers analyzed by the Watson error category. And the percentage of student error type in solving the problem of mathematical communication based on categories of error according to Watson is (inappropriate data/ ID) including into error which is high enough that is equal to 38%, (inappropriate procedure/IP) including into error which is quite high at 34%. (omitted conclution/OC) error is included to a fairly low error of 26%. While (ommited data/OD), (response level conflict/RLC), (undirected manipulation/UM), (skills hierarchy problem/SHP), and (above other / AO) of 0% each, including into very low errors.

Abstract

Pendekatan yang berpeluang dapat meningkatkan disposisi matematis siswa adalah pembelajaran berbasis masalah, sehingga tampil aktif dan memberi respon yang positif terhadap pembelajaran matematika. Oleh karena itu, penelitian ini bertujuan untuk mengetahui bagaimana peningkatan dan pencapaian disposisi matematis siswa sekolah menengah pertama yang menggunakan pendekatan pembelajaran berbasis masalah dengan yang menggunakan pendekatan konvensional. Metode penelitian yang digunakan adalah kuasi eksperimen. Populasi yang diambil adalah siswa SMP Negeri di Purwakarta dengan sampel kelas VIIA dan kelas VIIB. Instrumen dalam penelitian ini adalah instrumen non-tes berupa skala disposisi dan skala pandangan siswa terhadap pembelajaran berbasis masalah.Analisis data yang digunakan adalah uji perbedaan dua rata-rata yaitu uji t, uji t’ dan uji Mann Whitney. Hasil penelitian menyatakan bahwa disposisi matematis siswa yang pembelajarannya menggunakan pendekatan pembelajaran berbasis masalah lebih baik daripada siswa yang pembelajarannya menggunakan pendekatan konvensional. Sementara pandangan siswa terhadap pembelajaran berbasis masalah menunjukkan kriteria yang cukup. Pendekatan pembelajaran berbasis masalah sebaiknya digunakan dengan perencanaan yang matang karena memerlukan waktu yang relatif lama dalam pelaksanaannya.

Abstract

This research seeks to explore and reveal students' mathematical problem solving abilities by analyzing student answers. The research subjects were seventh grade students taken from a public junior high school in Purwakarta Regency. The results of the study show that students' mathematical problem solving ability is still very weak and far to be complete even though the level of difficulty of the instrument is in the medium category. In general, the ability of these study subjects in mathematical problem solving is still below 50%. It is time for teachers to apply problem-based learning, in addition to conventional learning models, to provide opportunities and experiences for students to see and experience mathematical problem solving in the classroom. This qualitative study exposes students' responses in dealing with story questions in a rectangular building material. In addition the students are given the questions shown to reveal whether the students are using a systematic solution or can answer directly without a sequence, judging by the ability to solve mathematical problems. There were 6 heterogeneous students who were the subjects in this study. Based on the analysis that has been done, the results obtained are (1) students answer the problem is not systematic, (2) lack of understanding of the sequence of problem solving, (3) students are too hasty in doing math problems.
