Abstract

Artikel ini menyajikan hasil penelitian menggunakan pendekatan kuantitatif dan metode penelitian eksperimen dengan desain the randomized solomon four-group design, yang dilakukan terhadap mahasiswa semester VI tahun akademik 2014-2015 pada mata kuliah Persamaan Diferensial Tujuan penelitian ini selain untuk membandingkan kemampuan berpikir kreatif matematis dari kelompok mahasiswa yang diberi perlakuan model pembelajaran problem posing atau tidak, juga untuk membandingkan kemampuan berpikir kreatif dari kelompok mahasiswa yang diberi pretes atau tidak. Berdasarkan analisis data menggunakan one way ANOVA, diperoleh hasil penelitian yang menunjukkan bahwa: 1) pada taraf kepercayaan 95%, terdapat perbedaan kemampuan berpikir kreatif matematis yang signifikan antara kelompok mahasiswa yang diberi perlakuan model pembelajaran problem posing dengan yang tidak; dan 2) pada taraf kepercayaan 95%, tidak cukup bukti untuk menyatakan bahwa terdapat perbedaan kemampuan berpikir kreatif matematis antara kelompok mahasiswa yang diberi pretes dengan yang tidak. Dengan demikian, perbedaan kemampuan berpikir kreatif matematis yang terjadi disebabkan oleh adanya perlakuan model pembelajaran problem posing bukan disebabkan oleh pemberian pretes di awal perkuliahan.Kata kunci: Kemampuan Berpikir Kreatif Matematis, Model Pembelajaran Problem Posing, Persamaan Diferensial

Abstract

The purpose of this research i.e. to analyze the ability of student’s mathematical representation in the course of geometry system based on the background of learning achievement of transformation geometry courses. This research is a quantitative research with the exposed facto method. The ex-post facto method is an empirical method of finding that is done systematically, the researcher does not control the independent variables because the manifestation has happened or those variables inherently cannot be manipulated. In this study, the attachment between the ability of mathematical representation and the background of learning achievement of the course of transformation geometry has occurred naturally, and the researchers with the setting want to trace back what are the factors causing it. The research design used is the basic causal-comparative design. Population in this research is all student of semester VI of the academic year 2016

Abstract

Correspondence analysis has been widely applied in various fields as a graphical method to depict the association structure between two categorical random variables on a low-dimensional plot. This study built a simple algorithm to determine the principal coordinates and construct the circular confidence regions on the correspondence plot. In this algorithm, the determination of the standard residual matrix and the principal coordinates is built directly from the contingency table (without calculating a correspondence matrix). The algorithm was developed using R and applied to data on Covid-19 cases in West Java.
