Abstract

Abstract: The purpose of this study was to determine the improvement of critical thinking skills and students mathematical dispositions, as well as the interaction between learning factors and grouping of students to the critical thinking skills and the improvement of student mathematical dispositions. This study is an experimental study with a quantitative approach that describes an increase in critical thinking skills and dispositions of students overall mathematical and grouping students. The population inthis study were students of SMP Negeri 3 Peusangan, where in the sample is a class VIII student as much as 2 classes with 47 students enrolled. The sampling technique is done by simple random sampling design with pretest-posttest control group. Based on the results of the study concluded that the improvement of students critical thinking skills mathematical significantly higher in grade PBM than conventional class as a whole with a value of t = 4.373. However, the grouping of students simply an increase in the high group and medle group only, namely the value of t = 4.064 and t = 2,554. The study also concluded that there was an interaction between learning factors and grouping of students to the mathematical ability of students to think critically. In addition, the results of a study of students mathematical dispositions that get higher problem-based learning than students who received conventional teaching overall with a value of t= 4.214. While the grouping of students is only an increase in the high group with a value of t = 2.428 and the low group with a value of t = 3.439. But in the process of interaction, there is no interaction between factors of learning and grouping of student to an increase students mathematical dispositions.  Keywords: Model problem-based learning, critical thinking skills, students mathematical   dispositions.

Abstract

Abstract. The low ability of students mathematical understanding and communication as well as the importance of both the enhanced capabilities require a learning model that provides the opportunity for students to construct their own knowledge, one of models is generative learning model. For this reason, researchers interested in conducting research on the application of generative learning model in mathematics learning activities. This study was an experimental study with quantitative approach aimed to obtain the increase in the ability of students mathematical understanding and communication in mathematical learning using generative learning model reviewed based on the overall student and the student level. This study used a pretest-posttest design with control group. Data collecting by using a test to determine the gain of ability students mathematical understanding and communication. Based on analysis of the data concluded that (1) the increase of students mathematical understanding abilities which learning obtain by generative models better than the increase of students mathematical understanding abilities taught by conventional learning reviewed by overall student or student level, (2) the increase of students mathematical communication abilities taught by learning generative models better than the increase of students mathematical communication abilities which taught conventional learning reviewed based on the overall student and the student level,    (3) there is no interaction between the factors of the learning approach with the level of mathematical ability and the increase of students mathematical understanding, and (4) there is no interaction between factors learning aproach and the level of students to the improvement of students mathematical communication abilites.Keywords: mathematical understanding abilities, mathematical communication abilities, generative learning model, conventional learning.
