Application of Guided Finding Methods in Mathematics Learning to Improve Representation and Problem Solving Abilities

Abstract

This research aims to determiming the application of the guided discovery method in mathematics learning to improve representation skills and mathematical problem solving. The research approach used in this research is a quantitative approach with a quasi-experimental research type. The design used is the pretest-posttest control group. The population was all students of class X MAN 9 Jombang, with sampling using random assessment techniques. The sample in this research was students of class X-MIA 2 and divided into two groups, the first group as the experimental class and the second group as the control class. The instrument used was a test and non-test. The test instrument used in this study was a description question to measure the students' mathematical representation and problem solving abilities. While the non-test instrument used in this study was an observation sheet to measure to observe all activities and behavior during learning activities. The data analysis technique used in this research is hypothesis testing, but before testing the hypothesis, prerequisite tests must be carried out, namely the normality test and the homogeneity test. Based on the Mann-Whitney U test, it shows the significance value of students' mathematical representation abilities of 0.131 ≥ 0.05, because the Sig. (2-tailed) ≥ 0.05 then Ho is accepted and Ha is rejected, meaning that there is no increase in mathematical representation ability by applying the method. invention. While the results of the calculation of the hypothesis using the independent sample t-test show that the significance value is 0.000 ≤ 0.05, because the Sig. (2-tailed) value ≤ 0.05 then Ho is rejected and Ha is accepted, meaning that there is an increase in mathematical problem solving abilities students with the application of the guided discovery method.
