Abstract

This study aims to find out the effectiveness of the Logan Avenue Problem Solving (LAPS)-Heuristic learning model assisted by flash card math media towards increasing the mathematical problem solving abilities of  grade students. This study was quantitative with a quasi-experimental type and a Nonequivalent Control Group Design. The population in this study were  grade of SMP Negeri 1 Paguyangan, total was 330 students. The sampling technique used simple random sampling. From the sampling, two classes were obtained, namely class VII G as the experimental class which was subjected to the Logan Avenue Problem Solving (LAPS)-Heuristic learning model assisted by flash card math media and class VII H as the control class which was not subjected to the model and media. In this study the instruments used were tests in the form of pretest and posttest. The results of this study there are found the differences in the average ability of students in the experimental class and the control class. This is reinforced by the average results of the experimental class more than the average results of the control class. The logan avenue problem solving (LAPS)-Heuristic learning model assisted by flash card math media was stated effective enough to improved students' mathematical problem solving abilities with the results obtained that the average percentage of N-Gain in the experimental class is 66.47% and the control class is 25.30% with an ineffective interpretation.

Abstract

This study aims to determine the effectiveness of the GI-type cooperative learning model assisted by comic media on increasing the mathematical literacy skills of class VIII students of SMP Negeri 1 Punggelan. This research is an experimental research with a quantitative approach. The population in this study were students of class VIII SMP Negeri 1 Punggelan and the samples used were taken by simple random sampling technique and the sample results obtained were students of class VIII G and class VIII H, totaling 58 students. The instrument used in this study was a description test consisting of a pretest and a posttest. The results of this study are that the average mathematical literacy ability of students who are subjected to the GI type cooperative learning model assisted by comic media is better than those who are not subjected to it, as seen from the results of the N-Gain test, namely the experimental class obtained an average N-Gain value of 0 .77 with high criteria, while in the control class the average N-Gain value for the control class was 0.47 with moderate criteria. In the t-test, the two independent samples showed a significance result of 0.000 <0.05, meaning that there was a significant difference in students' mathematical literacy skills between the experimental and control classes. The GI type cooperative learning model assisted by comic media was declared effective for increasing mathematical literacy skills with the average N-Gain test results obtained in the experimental class by 77% with effective criteria and in the control class by 47% with less effective criteria.
