Abstract

This study aims to find out empirical data from the analysis of Electronic School Books (BSE) for students of Class IX Middle Semester I. There are 3 (three) triangles elements, namely the vertex, angle and length of the sides of the triangle, each consisting of 3 (three). But to determine the existence of a triangle requires only two elements, namely the angle and length of the sides of the triangle. However, not the two elements that are used to determine the existence of a triangle, but each must be known. To determine it enough to know 3 (three) elements of the two elements, namely: a. The length of the three sides, b. The length of both sides and one of its angles, c. The length of one side and the size of both angles. The results of the study based on literature review found an error that the BSE Student Mathematics book for class IX contained a triangular image error with 5 elements of two elements (3 side lengths and 2 angles) which proved impossible after analysis using painting and trigonometric calculations.

Abstract

The purpose of this research is to describe: (1) the achievement and the interest in mathematics learning of the students taught using the CTL method and that of those taught using the Open-Ended method in the material on probability, (2) the effect of students’ mathematics learning styles on their achievement of mathematics on probability material, (3) the effect of students’ mathematics learning styles on their learning interest in mathematics on probability material, (4) the effect of teaching method and  students’ mathematics learning styles on their achievement and interest in learning mathematics on the probability material. This research used a quasi-experimental research design by two experimental groups. The analysis of the data used normality and homogeneity testing, the multivariate analysis, and the post-hoc test involving the Bonferroni procedure.The results of the research are as follows: (1) In the probability material, the group of students taught by the CTL method has better achievement and mathematics learning interest than that of those who are taught using the Open-Ended learning method. (2) There is an learning style effect (auditory, visual, and kinesthetic) on their achievement of mathematics in the probability material.(3) There is an effect of learning style (auditory, visual, and kinesthetic) on their learning interest in mathematics probability material. (4) There is no effect of teaching method and students’ mathematics learning styles on their  achievement and learning interest in mathematics in the probability material. Keywords: CTL, Open-Ended, learning styles, achievement, learning interest
