Abstract

This study aims to obtain a description of the problem solving profile of SPLTV students of class X SMA Negeri 1 Banawa Tengah in terms of mathematical ability. This study uses a qualitative method with a qualitative descriptive approach. The research subjects were 3 students, namely students who had high, medium and low mathematical abilities based on the problem solving steps proposed by Polya. The results obtained indicate that: (1) Students who have high mathematical abilities use all stages of Polya in solving SPLTV problems. (2) Students who have moderate mathematical ability have not been able to use all of Polya's stages in solving SPLTV problems, the stages in question are in the re-examination stage. However, the subject gives his opinion by explaining using his own language why not re-examine the results of the completion of the given problem. (3) Students who have low mathematical abilities have not been able to go through all the stages of Polya in solving problems, the subject is only able to go through the stage of understanding the problem but the subject needs to read and pay attention to the information on the problem repeatedly.

Abstract

This study aims to describe the application of learning modelsProblem Based Learning (PBL) the can improve the learning outcomes of class VIII E students of SMP Negeri 13 Palu on the material of straight line equations. This type of research is Classroom Action Research (PTK) and its design uses the Kemmis and Mc. Taggart, namely planning, action, observation, and reflection. The subjects of this research were all students of class VIII E SMP Negeri 13 Palu with a total of 30 students and three students were selected as informants. The results showed that through the application of learning modelsProblem Based Learning (PBL) can improve student learning outcomes by following the model phasesProblem Based Learning as follows: (1) students' orientation to problems, (2) organizing students to learn, (3) assisting individual and group investigations, (4) developing and presenting work, and (5) analyzing and evaluating the problem-solving process. Based on the data on learning outcomes in cycle I, it can be seen that the mastery of classical learning reached 30% and in cycle II it was 76.6%. Furthermore, the results of observations in cycle I on teacher activity obtained a score of 30, which was included in the good category and the results of observations of student activities obtained a score of 26, which was included in the less category based on the intervals previously made. Then the results of observations in cycle II on teacher activity obtained a score of 38 which was included in the very good category and the results of student activities obtained a score of 35 which was included in the good category based on the intervals previously made.
