Abstract

The Ministry of Education and Culture (2016) states that one of the learning objectives in the 2013 curriculum is to develop creative activities that involve imagination, intuition, and discovery by developing divergent, original thinking, curiosity, making predictions and guesses, and experimenting. The fact that the creative thinking ability of Indonesian students is still low is shown in the results of the Program for International Student Assessment (PISA) in mathematical ability, placing Indonesia at 62 out of 70 countries (OECD, 2016). The provision of problem-posing model questions is expected to stimulate students to think creatively by generating new ideas or ideas to develop existing information and finally students begin to propose new problems according to their understanding of the mathematical concepts being studied. The purpose of this study was to describe students' mathematical creative thinking ability seen from the indicators of creative thinking abilities, namely fluency, flexibility and novelty in solving problem posing question. The research method used is a survey method with the research subject being class VIIIG SMPN 1 Malang. The results obtained, the average score of the fluency indicator is 14.81 or 87.10% in the high category, the average score of the flexibility indicator is 4.64 or 51.61% in the low category, and the novelty indicator is 1.16 or 6, 45% with low category. This shows that the creative thinking ability of students in solving problem-posing questions is low.

Abstract

This research aimed to analyze student literacy ability in Mathematic teaching in Muhammadiyah Senior High School (SMA Muhammadiyah) of Kupang. This research was qualitative descriptive. Subject here was student of SMA Muhammadiyah class XI MIA in Kupang. These students were categorized firstly in three ability categories i.e., high, middle, and low. Two students was taken in each category. The object here was the analysis of students’ literacy ability at SMA Muhammadiyah Kupang to solve problems in linear program. Technic in this study was purposive sampling. Data was analyzed based on test and interview results. The validity was checked using triangulation method by comparing the obtained data in interview test. Results show that the student literacy ability in mathematic was high and fulfill all indicators. Student was able to formulate mathematic model and real problems of linear program, and give implementation mathematic model design to solve mathematic solution. Student with middle literacy ability only have two indicators. These students able to make decision to problems, know some parts that needed in order to making problem model in mathematics, then make evaluation on it. Student with low literacy ability only have one indicator, which is formulate indicator. By this indicator those students able to change problem to suitable mathematic model in variable form. There for some efforts was needed in order to increase mathematic literacy to students.

Abstract

The objective of this study is to determine errors and causal factors in junior high school students in solving mathematical problems in comparative material. The descriptive qualitative method was used in this study. This study was conducted at SMP Muhammadiyah Kupang. Six students participated in this study, with two students having high abilities, two students having moderate abilities, and two students having low abilities. Written examinations centered on comparison material and interview results were used to collect data. The results of the tests and interviews were analyzed based on the indicators of the types of errors and the causal factors, namely: concept errors, principal errors and operational errors. The results showed that. (1) Student with high category abilities, made one mistake, namely an operation error, the subject was wrong in the process of calculating the final answer. (2) Students with moderate categories make mistakes, namely, prinsi errors, principle errors do not write comparison formulas when solving problems. (3) Students with low categories i.e. subjects commit misconceptions, i.e. subjects have difficulty in determining concepts from comparisons.

Abstract

Salah satu topik yang penting dalam pembelajaran matematika adalah Teorema Pythagoras, yang memerlukan kemampuan representasi matematis yang baik agar siswa dapat memecahkan masalah dengan tepat. Model pembelajaran Collaborative Problem Solving (CPS) telah diakui sebagai pendekatan yang dapat meningkatkan pemahaman konseptual dan kemampuan berpikir kritis melalui kerja sama dan interaksi antar siswa. Oleh karena itu, penelitian ini bertujuan untuk mendeskripsikan kemampuan representasi matematis siswa pada materi Teorema Pythagoras menggunakan model pembelajaran collaborative problem solving. Metode penelitian yang digunakan adalah penelitian deskriptif kuantitatif. Subjek penelitian ini adalah siswa kelas VIII MTs Plus Nurul Iman. Instrumen yang digunakan meliputi tes kemampuan representasi matematis dan lembar observasi proses pembelajaran. Data yang diperoleh dianalisis dengan menggunakan statistik deskriptif untuk menggambarkan kemampuan representasi matematis siswa, serta menganalisis efektivitas model pembelajaran CPS. Hasil penelitian menunjukkan bahwa penerapan model CPS mampu meningkatkan kemampuan representasi matematis siswa pada materi Teorema Pythagoras, terutama dalam aspek representasi gambar, simbol dan verbal. Siswa yang belajar dengan model CPS cenderung lebih aktif dalam berdiskusi dan bekerja sama dalam menyelesaikan masalah, sehingga lebih mampu mengintegrasikan berbagai bentuk representasi matematis. Meskipun demikian, representasi verbal masih menjadi tantangan bagi beberapa siswa.
