Abstract

This study aimed to see differences in the ability of understanding the mathematical concepts that students taught through cooperative learning model jigsaw with conventional learning on eighth grade students of SMPN 18 Bengkulu academic year 2013/2014. This research is a quasi experimental study. The study population is the entire eighth grade students of SMP Negeri 18 Bengkulu city. The research sample determined by random sampling technique and obtained  VIII.2 classes to taling 30 students as classroom control, and VIII.3 graders who totaled 30 students as a class experiment. The data collected is the data from the pre-test and post-test students' comprehension of  mathematical concepts, the data were analyzed using t-test. The results of this study indicate that while t table t count=2.1652785=2.00172 which means that there are differences in the ability of students' understanding of concepts taught through cooperative learning model jigsaw with conventional learning on eighth grade students of SMPN 18 Bengkulu academic year 2013/2014. Based on the results of this study concluded that the Jigsaw cooperative learning model affect the ability of students 'understanding of the concept compared to conventional learning, so that there are differences inthe ability ofstudents'understanding of mathematical concepts of these two classes.Keywords: ability of understanding the mathematical concepts, Jigsaw cooperative learning model

Abstract

Indonesian students' mathematical literacy based on PISA and PIRLS assessments is still in the low category. Mathematical literacy covers how students are able to know and use basic mathematics to solve problems in real life contexts. Problem Based Learning Model is a learning model that can solve problems in real life contexts by facilitating the development of junior high school students' mathematical literacy. The main principle of Problem Based Learning emphasizes mathematical problems that are human activities and must be meaningful for students, become a motivator to improve mathematical literacy skills through the stages of learning. This article examines the mathematical literacy ability of SMP Negeri 11 Bengkulu students before and after going through the Problem Based Learning Model. Students' mathematical literacy skills prior to the application of the Problem Based Learning model have a percentage of 25% for the medium category and 75% are in the low category. Then for students' mathematical literacy ability after applying the Problem Based Learning model has a percentage of 5% for the medium category, 90% is in the low category, and 5% is in the high category. The results of inferential statistical analysis (Paired Sample T-test) obtained a significance value 0.05. This means that there is an increase in students' mathematical literacy skills after the application of the Problem Based Learning model in class VII SMP Negeri 11 Bengkulu City.Keywords: Literacy Ability, Problem Based Learning

Abstract

This study was aimed to know the differences in students' mathematical problem solving skills in problem basedlearning models with cooperative type thinking aloud pairs problem solving with a scientific approach at SMA Negeri 7 Bengkulu. Thedesign of this research was a quasi-experimental, used a pre-test post-test control group design. The population in this study were all students of class X MIPA SMA Negeri 7 Bengkulu consist of 6 classes, with samples consist of 3 classes, the first experimental class with the problem based learning model, the second experimental class cooperative learning model type thinking aloud pairs problem solving and conventional learning as a control class. The sampling technique used simple random sampling. Data collection was done by using a test of students' mathematical problem solving skills. The results of the research data were analyzed using one-way ANAVA test and BNT test. The prerequisite test used the Kolmogrove-Smirnov test to see normality and Bartlet's test to see homogeneity. The significant level used is 0.05. The research data showed  that there was a significant difference in students' mathematical problem-solving ability in the learning model of Problem Based Learning, cooperative type thinking aloud pairs problem solving in SMA Negeri 7 Bengkulu, and problem based learning learning model which gives better results compared to the thinking type cooperative learning model thinking aloud Pairs problem solving at SMA Negeri 7 Bengkulu.Keywords: mathematical problem solving, PBL,TAPPS
