The background of this research was the low ability of student’ mathematical learning outcomes of SMA Negeri 8 Pekanbaru. The purposes of this research were: 1) to find the significance of students’ mathematical learning outcomes who study through Problem Based Learning (PBL) model with student who study through conventional learning with scientific approach; (2) to examine the improvement of students’ mathematical learning outcomes who study through PBL model and students who study through conventional learning with scientific approach in class XI-MIPA SMA Negeri 8 Pekanbaru. This research was an experimental research (quasi experiment) with The Nonequivalent Pretest-Posttest Control Group Design. The population of this research is all students of class XI-MIPA SMA Negeri 8 Pekanbaru. Sample of this research consist of two classes, class XI-MIPA4 as experiment class and XI-MIPA3 as control class. The data of this research were student’s mathematical learning outcomes from pretest-posttest. Students’ mathematical learning outcomes were analyzed using independent sample t-test which was preceded by normality test and homogeneity of variances test. The result of this research shows that the improvement of students’ mathematical learning outcomes who study through PBL model is higher than students who study through conventional learning with scientific approach.

This research is motivated by the limited mathematics learning devices that are in accordance with the 2013 Curriculum. This research purposed is to produce mathematics learning devices such as syllabus, lesson plans, and student worksheets by using problem based learning on sets material for the seventh grade of junior high school. The development model used in this research is the 4-D model which consists of the stages of define, design, develop, and disseminate. The learning devices that have been developed were validated by three validators and revised according to suggestions from the validators. The average score of the validation results for the syllabus, lesson plans, and student worksheets are 90.25%, 91.25%, and 91.75% with very valid categories. The results of this validation indicate that the syllabus, lesson plans, and student worksheets are feasible to be tested. Researcher conducted trials one by one on six students to see the students responses and readability to student worksheets developed with a problem based learning model. It was found that the student worksheets being developed can help them in studying the set material, is easy to understand, the explanation is clear enough and the students worksheets looks interesting. Based on the results of data analysis and discussion it can be concluded that the syllabus, lesson plans, and student worksheets by using problem based learning model on sets material for the seventh grade of junior high school has fulfilled valid.
