Abstract

This study is a pretest-postest experiment control group design having a goal to analyze the role of scientific approach on mathematical critical thinking ability and disposition. The study involved 70 eleventh grade of vocational high school students, a test on mathematical critical thinking, a disposition scale, and a scale of students’ perception on scientific approach. The study revealed that students getting treatment on scientific approach attained better grades on mathematical critical thinking ability and disposition than that of students taught by expository teaching, though the mathematical critical thinking ability grades were at medium level and the grades of disposition were at fairly good level. Besides that, students performed positive opinions toward scientific approach and there was association between mathematical critical  thinking ability and disposition.

Abstract

This study aims to produce teaching materials based on the GeoGebra-assisted Problem Based Learning approach that are valid, effective and practical to improve mathematical mathematical communication skills in linear programming material. The subjects in this study werw 30 students for a limited trial, 60 students for a broad trial, and 60 students for product testing including 30 experimental class and 30 control class. The instruments used in this study were interview sheets, student observation sheets on learning, response questionnaires to learning, validation questionnaires, five questions about mathematical communication ability tests, and non-test questionnaires for students' self-confidence. The results of this study indicate that the process of developing teaching materials is carried out well and the product is feasible to use, mathematical communication skills and self-confidence of students who receive learning using the GeoGebra-assisted Problem Based Learning method are better than students who receive learning using the usual approach, difficulties during learning do not indicate a high level of difficulty, in terms of mathematical communication problems students have difficulty in perfoming algebraic operations and more than half of students respond positively to learning.
