Abstract

Penelitian ini mengkaji perbedaan hasil belajar model pembelajaran interaktif dengan setting kooperatif (model PISK) dengan model pengajaran langsung (model PL). Dalam tiga aspek, yakni kemampuan berpikir kritis, penguasaan bahan ajar, dan sikap terhadap matematika serta gaya kognitif dilibatkan sebagai variabel moderator. Hasil belajar siswa SLTP Negeri 4 sebagai kelompok eksperimen, dan SLTP Negeri 6 sebagai kelompok control dianalisis dengan menggunakan Analisis Varians Multivariat Dua Jalur (Two Way Manova).Hasilnya menunjukkan bahwa pembelajaran matematika dengan menggunakan model PISK lebih baik dibandingkan dengan menggunakan model PL, dan hasil belajar matematika siswa field independent lebih baik pada siswa field dependent.This research aims at investigating the defferent learning results-getvees those using Interactive leasning with cooperative setting model (PTSK) and those using Direct Instructian (PL model). Whereas the moderatos variables consisted of three aspects, I,e; (1) critical thinking abicity, (2) mastery of cearning material and (3) attitude and cognitive style towarde mathematics. The learning achievemcats of students of SLTP Negeri 4, ambon as an experimental gsorep and those SLTP Negeri 6 as a control groep werw analysed using Two-way manova. The finding shows that the learning of mathematics using PISK model is getter than that using PL model, and the learning result of field independent students is getter than that of the field dependent.

Abstract

In learning mathematics, representation and communication ability are required by students to solve problems. The ability to represent is crucial for students to simplify the learning process, while students who have good mathematical communication abilities can easily solve a problem. This study applied a sequential mixed methods approach. Quantitative data was obtained from the results of the written test, then the ability of mathematical representation and communication in solving problems on linear program material was analyzed qualitatively. The participants of this study were 59 students from one of the senior high schools in Ambon, Indonesia. The research phase was begun with students being asked to solve mathematics problems and then researchers analyze representation and written communication ability. The largest percentage of students' results on the test was in the very low category of mathematical representation and communication ability. The results showed that students who had good representation and communication abilities would be able to solve problems. There were significant correlations and a very strong correlation between mathematical representation and communication ability with a Pearson Correlation coefficient of 0.915. After obtaining the test result, subjects were selected based on the category of ability to conduct interviews. Based on the results of the interview, the mathematical representation ability that the subject uses well will directly involve mathematical communication skills well, and vice versa.
