Abstract

This study aims to determine the comparison of student learning outcomes using a scientific approach and learning model Problem Based Learning. This type of research uses the Classroom Action Research (CAR) method or can be referred to as (Classroom action research) and mix methods (Quantitative and Qualitative). The subject of this study was located at SMP Negeri 3 Cimahi in class VIII-I with a total of 34 students. Data collection techniques with pre-test and post-test. The results showed that there were differences in mathematical problem solving abilities between students who used a scientific approach and students who used the Problem Based Learning learning model. The results showed that the application of the Problem Based Learning model could improve students' mathematical problem solving abilities from cycle I to cycle 2 by 10%. The results of the research show that the Problem Based Learning (PBL) model can improve problem solving abilities in the material on the System of Two Variable Linear Equations (SPLDV). This research can be concluded that the ability to solve problems in SPLDV material can be increased by applying the problem based learning model.

Abstract

The lack of students' mathematical problem solving abilities causes difficulties in solving problems, especially with statistical data. The research objective is to describe students' abilities in solving mathematical problems related to statistics. Qualitative methods are used as research methods. Participants who were taken as research subjects consisted of 80 class VIII students of SMPN 1 Parongpong. Subjects were divided into three groups, namely students with high abilities (10), students with moderate abilities (45), and students with low abilities (25). Data collection techniques used test questions in the form of student math problem solving tests and questions in the form of essay tests. The results showed that overall the students' mathematical problem solving abilities were in the high category, totaling 8 people with a percentage of 10% with a criterion score of less than 79.43. The ability to solve mathematical problems in the moderate category is 42 students with a percentage of 52.5% and an initial score of 36.56 to less than 79.43. On the other hand, there are 30 students in the low category with math problem solving abilities which have a percentage of 37.5%, and an initial score of less than 36.5.
