Abstract

Geometry is one of the critical subjects of mathematics. It includes concepts as points, lines, planes, space and their relations. Representations of three-dimensional objects using two-dimensional diagrams bring the difficulties of identification of their properties. The subfactors of spatial ability were identified as the primary variables in the performances of students related to geometry subject. The purpose of this study is to investigate the relationship between spatial visualisation and spatial orientation to the students understanding of space geometry concepts matter of the eighth-grade students. There are 60 eighth grade students as a  sample of the study. The reliability and the validity studies of the tests were carried out In the first part of the study. In the second part, correlation and regression analyses were carried out. Significant correlations were found between each factor. For clarifying the relationships between more than one-factor multiple regression analyses were used. The results showed that the two predictor variables explained the 65,61 % of the variance in plane geometry test scores. However, a degree of contribution of each factor differed. The relative impact of spatial orientation ability (B=. 55) was higher than the spatial visualisation ability (B=. 28).

Abstract

Problem-posing ability is the ability to make and solve math problems. This research is qualitative research that aims to describe the ability to submit questions about prospective elementary school teachers concerning mathematical disposition. The subject of this research is the students of prospective school level teachers in the 6th semester, amounting to 3 people. The results of this study are (1) prospective primary school teachers with a high mathematical disposition can submit questions based on the information given related to addition and subtraction of ordinary and mixed fractions, the problem presented are in accordance material with moderate difficulty level, able to solve the problems posed with using a good language structure, (2) prospective primary school teacher with a moderate mathematical disposition level can form a story question based on additional information and subtraction of ordinary fractions, the questions submitted are in accordance material with a relatively low difficulty level and using a good language structure. However, unable to solve the problems raised, and (3) prospective primary school teachers with a low mathematical disposition level are not able to ask questions based on the two information provided. The prospective teacher has difficulty making a story question. These conditions have an impact on not fulfilling several other criteria, among others, conformity with the material, answers to the problems raised, language structure and the difficulty level of the question. The results of the study provide recommendations for policymakers on campus to help prospective students of elementary school teachers to develop problem-posing ability according to the level of mathematical disposition.

Abstract

Kemampuan koneksi matematis merupakan kemampuan untuk mencari hubungan inter topik, antar topik, suatu topik dengan ilmu lain, atau suatu topik dengan masalah dalam kehidupan sehari-hari dalam bidang matematika. Kemampuan koneksi merupakan salah satu aspek yang harus dimiliki siswa agar berprestasi dalam belajar matematika. Penelitian ini merupakan penelitian kualitatif yang bertujuan mendeskripsikan profil kemampuan koneksi matematis siswa sekolah menengah atas (SMA) pada masalah fungsi komposisi. Penelitian ini melibatkan 36 orang siswa sekolah menengah atas dan dipilih 3 orang siswa sebagai subjek utama. Data kemampuan koneksi matematis dikumpulkan melalui tes, tugas, dan wawancara tidak terstruktur sesuai dengan tugas yang diberikan. Data dianalisis secara kualitatif untuk memahami, menelaah, dan menafsirkan koneksi matematis siswa sekolah menengah atas pada masalah fungsi komposisi. Hasil penelitian menunjukkan bahwa (1) siswa sekolah menengah atas dengan tingkat disposisi matematis tinggi memiliki kemampuan koneksi matematis yang baik. Siswa tersebut mampu melakukan koneksi baik inter topik maupun antar topik. Selain itu juga, mampu melakukan koneksi materi matematika dengan bidang lain maupun materi matematika dengan kehidupan sehari-hari, (2) siswa sekolah menengah atas dengan tingkat disposisi matematis sedang memiliki kemampuan koneksi matematis yang cukup baik. Siswa tersebut mampu melakukan koneksi baik inter maupun antar topik dalam matematika. Namun, belum dapat melakukan koneksi matematika dengan bidang lain atau koneksi materi matematika dengan kehidupan sehari-hari, dan (3) siswa sekolah menengah atas dengan tingkat disposisi matematis rendah memiliki kemampuan koneksi matematis yang kurang baik. Siswa SMA dengan tingkat disposisi matematis yang rendah mampu melakukan koneksi inter topik dalam materi matematika. Namun, siswa tersebut masih sangat kesulitan dalam melakukan koneksi antar topik dalam matematika, dan juga kesulitan dalam melakukan koneksi materi matematika baik dengan bidang lain maupun dengan fenomena dalam kehidupan sehari-hari. Hasil penelitian ini memberikan kontribusi berupa masukan dan rekomendasi bagi guru matematika dan penentu kebijakan di sekolah menengah atas agar membimbing dan meningkatkan kemampuan koneksi matematis siswa sesuai dengan tingkat disposisi matematis.

Abstract

Kemampuan penalaran matematis merupakan kemampuan yang sangat penting dimiliki siswa agar berprestasi dalam matematika. Penelitian ini merupakan kuasi eksprimen yang bertujuan untuk mendeskripsikan perbedaan kemampuan penalaran matematis siswa yang menggunakan model pembelajaran Pengajuan Soal dengan yang menggunakan model pembelajaran Student Teams Achievement Division (STAD). Penelitian ini menggunakan posttest only control design dengan sampel penelitian untuk kelas eksperimen berjumlah 32 siswa yang menggunakan model pembelajaran problem posing dan kelas kontrol berjumlah 32 siswa yang menggunakan model pembelajaran tipe STAD. Data yang dikumpulkan dalam penelitian ini yaitu data kemampuan penalaran matematis siswa. Data tersebut dianalisis dengan menggunakan uji t rumus separated varian. Hasil analisis data penelitian menunjukkan bahwa mean kemampuan penalaran matematis kelas eskperimen dan kontrol yaitu sebesar 66.69 dan 55.38. Berdasarkan hasil pada taraf signifikaansi sehingga H0 ditolak dan H1 diterima berarti kemampuan penalaran matematis siswa yang menggunakan model pembelajaran problem posing lebih baik dibandingkan siswa yang menggunakan model pembelajaran Student Teams Achievement Division. Hasil penelitian tersebut menunjukkan bahwa model pembelajaran problem posing sebaiknya diterapkan dalam pembelajaran di kelas untuk membantu siswa dalam meningkatkan kemampuan penalaran matematisnya.
