This research is motivated by the students’ mathematical problem solving ability is still low and even tends to go down. Based on the results of the international study TIMSS (Trends in International Mathematics and Science Study) and the Program for International Student Assessment (PISA) in 2015 showed that in general the ability of Indonesian students is very low in understanding complex information and problem solving. (SMA) or Vocational High School (SMK) in Indonesia has decreased. The change ranged from 61.93 to 55.03. Judging from the average achievement of the 2016 National Examination results for senior high school (SMA) level in Kampar district is still below the minimum standard of completeness. In addition, students’ Self-Efficacy is still low. This is based on the observations of researchers at SMA Negeri 2 Bangkinang city, seen several symptoms including: 1) Not trying to achieve high grades in the academic field, students often get low grades. 2) Some students are lazy to do math practice questions; often too late to collect assignments because they are not sure and are not confident in their abilities. Based on the analysis of these facts, the problem is found that the Mathematical Problem Solving Ability (KPMM) and Self-Efficacy of students are assumed to be low. Seeing these problems, researchers conducted research aimed at analyzing the increase in KPMM and Self-Efficacy of students who obtained Problem Based Learning (PBL) learning models and students who received conventional learning with a scientific approach in terms of Early Mathematical Ability (KAM).
This research is a quasi-experimental research design with Pre-test Post-test control Group Design. The population in this study were all high school students in Kab. Kampar. The study was conducted in one school on the subject matter of sequences and sequences in class XI of SMAN 2 Bangkinang Kota, taken 6 classes, namely 3 experimental classes and 3 control classes totaling 183 people as samples. The division of the sample group is based on the initial mathematical ability of the results of the End of Semester I mathematics grade XI grade students of SMA Negeri 2 Bangkinang Kota in the 2018/2019 Academic Year, then a class average and standard deviation can be determined so that students with high KAM levels of the experimental group 17 people and the control group was 18 people, the KAM level was the experimental group 63 people and the control group were 63 people, while the low KAM level was the experimental group 11 people and the control group were 11 people. The data in this study are quantitative data in the form of assessment results of the problem solving ability of mathematical problems (Pretest-Posttest) and Self Efficacy of students in the experimental class and the control class. The instruments used in this study are: 1) Learning tools in the form of: syllabus, lesson plans, and LKPD; 2) KPMM test instrument and Self-Efficacy questionnaire Data collection techniques used in this study were the data analysis of KPMM test results and the Self Efficacy questionnaire. To collect KPMM data, a written test technique is used in the form of KPMM pretest and KPMM posttest in the form of description items. As for the Self efficacy questionnaire, it is used as a tool to measure students’ confidence or confidence in their abilities before and after learning using the PBL model. The data that has been collected and then tested is started by calculating the N-gain score of each student. N-gain is an increase in scores taken from the pretest and posttest scores. After getting the N-gain score of each student, then testing is done. Data processing begins with the statistical prerequisite tests obtained as a basis for testing hypotheses, namely the normality test of the research subject data distribution, and the homogeneity test for each group of data tested. Furthermore, certain types of statistical tests are determined according to the problem, namely the average difference test, one-way ANOVA test and two-way ANOVA.
Based on the results of the study it can be concluded as follows: 1) there is a significant increase in KPMM between students who get Problem Based Learning (PBL) learning models and students who get conventional learning with a scientific approach in terms of KAM as a whole, high, medium, and low; 2) there is an interaction between the Problem Based Learning model and conventional learning scientific approach with the level of initial mathematical ability (high, medium, and low) to KPMM; 3) there are differences in KPMM students with the application of PBL model learning in terms of KAM; 4) there is a significant increase in Self Efficacy between students who get PBL model learning and students who get conventional learning with a scientific approach in terms of KAM as a whole; 5) there is an interaction between the learning model and the KAM level to increase Self Efficacy; and 6) there is a difference in the Self Efficacy of students who get PBL model learning in terms of KAM.
