PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) UNTUK MENINGKATKAN HASIL BELAJAR MATEMATIKA SISWA KELAS X MIA SMA NEGERI 1 LIRIK

Abstract

Abstract : This research aims to improve learning process and increase student’s mathematical achievement through implementation of Problem Based Learning (PBL)Model. This type of research is Classroom Action Research with two cycle. The research was conducted in class X Science 1 SMA Negeri 1 Lirik in the second semester of the 2017/2018 academic year. The subject of this research consist of 22 students, there are 12 female students and 10 male students.The research instrument consists of learning materials and instruments for collecting data. Learning materials used in this research are the Syllabus, Lesson Plan and Activity Sheets. Instrument data collectors used in this research are observation sheet and mathematical achievement test. Data analysis techniques in this study are descriptive narrative analysis of qualitative data and descriptive statistics analysis ofquantitative data. Application of PBL model also gives positive impact on the implementation of learning process that students become more active in learning activities so that learning is not centered on the teacher. Students are also trained to build their own knowledge and can find their own mathematical concepts through the presentation of problems close to the student's real life. The percentage of students which ispass Minimum Mastery Crieria (MMC) increase from 31,8% to 59,1% at the first test and to 77,3% at the second test. This research concludes that the implementation of PBL improved the learning process and the student’s mathematical achievement atclass X MIA 1 SMA Negeri 1 Lirik. PBL model can be used as an alternative to learning, because through this learning can improve the learning processand mathematical achievement of the students.
