Abstract

The purpose of this study is to describe students’ ability in solving mathematical representation problems evaluated from mathematical disposition.  The subjects are three students of 10th grade of public senior high school (PSHS) in Padalarang, West Java, Indonesia. They were selected from 35 students with high, medium, and low mathematical disposition ability. The results of the study showed that almost all of the students able to use visual representation to solve mathematical problems, and create mathematical models and solve problems by involving mathematical expressions. In contrast, most of students could not fulfill two indicators of the mathematical representation ability, i.e. creating the sketch of geometric patterns and making the mathematical model based on the situation and data given.

Abstract

Calculus is one of the subjects that must be taken by students majoring in mathematics education at the Teachers' Training College Siliwangi, this course is given to students in semester 4. From the analysis of learning obstacle, it can be seen that almost all mahsaiswa have difficulty learning in a calculus course. This is because the factors that influence in solving the problems given by the researchers. From the test results can also be seen the answer given by many students who make mistakes, be it in using formulas, operating, to answer directly without a process and students can not memjawab about a given test. These difficulties lead to poor results. It can be concluded that mahsiwa not been able to understand the material given or students only attend learning without any understanding of the material provided.

Abstract

Tujuan penelitian ini adalah mengembangkan tes berdasarkan kerangka kerja RECCE-MODEL untuk mengukur kemampuan kognitif mahasiswa. Subjek penelitian adalah 80 mahasiswa pendidikan matematika semester ganjil tahun akademik 2019/2020, Universitas Muhammadiyah Malang. Jenis penelitian yang diterapkan ialah Research and Development (R&D). Prosedur penelitian terbagi menjadi tiga tahapan, yaitu pengumpulan data, perencanaan tes, dan pengembangan tes. Penelitian ini menggunakan instrumen penelitian berupa lembar validasi dan tes. Hasil penelitian di antaranya menghasilkan 2 butir soal tes sesuai dengan kerangka kerja MODEL. Tes tersebut telah dilakukan uji validasi, uji reliabilitas, uji tingkat kesukaran tes, dan uji daya pembeda soal. Berdasarkan hasil validasi yang diujikan oleh validator, tes tersebut dikatakan valid karena hasil yang diperoleh adalah 75%. Nilai koefisien reliabilitas adalah 0,786 sehingga tes dapat dikatakan reliabel. Hasil analisis tingkat kesukaran dikategorikan mudah untuk keseluruhan tes. Hasil daya pembeda soal dikategorikan baik untuk keseluruhan tes. Selain itu, dengan menggunakan tes yang telah dikembangkan ini dapat mengidentifikasi kemampuan kognitif mahasiswa pada lima level MODEL. Oleh karena itu, dapat disimpulkan tes yang dikembangkan memiliki kategori valid, reliabel, dan efektif untuk mengukur kemampuan kognitif mahasiswa.

Abstract

Being able to think creatively is crucial for kids since creativity is required to address difficulties. The purpose of this research was to find out the characteristics of creative thinking ability of high school students in relation to a  two-variable linear equation system. This study was conducted in a  high school in West Bandung district, and one class, namely class VIII B, with 23 students participated in the study. The method  used in this study is a descriptive qualitative method. This study used test instruments and non-test instruments in the form of questions and interviews. The effects confirmed that students have been able to resolve questions based on only  two indicators of creative thinking ability, ie. fluency 55.32% and flexibility 68%, and students could not  solve tasks based on news indicators one 14,44%. Based on the results of the interviews, this resulted in students who generally could not work  and solve questions with their own answers or thoughts, but only procedurally followed the SPLDV problem solving method.

Abstract

One of the goals of learning mathematics is that students can demonstrate an accurate conceptual understanding of problem solving. The research was conducted at one of the MTs in West Bandung Regency. The purpose of this study was to determine the MTs students' understanding of mathematical concepts in fractional material using a qualitative descriptive method. Data collection techniques are conducting written tests, interviews and documentation on class VII students. The written test uses questions that are in accordance with the understanding of mathematical concepts. The characteristics of students' ability to understand mathematical concepts were categorized into 3, namely students who answered correctly (SMT) as many as 5 people (33.3%) on the indicator Presenting models and non-model objects of a concept and expressing concepts in various forms of mathematical descriptions, students who answered incorrectly (SKT) as many as 7 people (46.7%) on the indicator restating objects against a concept and categorizing objects according to their nature according to the concept, and students who did not answer as many as 3 people (20%) on indicators applying a concept or algorithm in problem solving.

Abstract

The ability to solve problems is an essential skill that students must have in everyday life and as an integral part of the math curriculum. The research aims to achieve and improve the mathematical problem-solving ability of junior high school students through the application of the STAD (Student Teams Achievement Divisions) cooperative learning model. The method used is a quasi-experimental design experiment. The results of the study found that before the implementation of the STAD model, students' mathematical problem-solving skills were still low, as seen from the results of the pre-test. This study concluded that cooperative learning STAD is effective in achieving and improving the mathematical problem-solving ability of junior high school students.
