PENINGKATAN HASIL BELAJAR MATEMATIKA SISWA MELALUI MODEL PROBLEM BASED INSTRUCTION (PBI) DENGAN METODE PENEMUAN TERBIMBING

Abstrak

The aim of this research is to improve students' mathematics learning outcomes through a problem-based learning model using the guided discovery method for class VIII students at SMP Negeri 2 Latambaga. This research was carried out in the even semester with a total of 28 students consisting of 9 men and 18 women. The procedures for this research are planning, implementing actions, observing and evaluating, and reflecting. The data sources in this research are mathematics teachers (partner teachers), observers and students. The type of data collected is quantitative data, in the form of student learning outcomes and qualitative data, namely the results of observations of teachers as researchers and of students. The data collected was analyzed using quantitative and qualitative analysis. The research results showed that the average value of students' mathematics learning outcomes in cycle I was 63.14% with a classical completion presentation of 37.03% but had not yet reached the predetermined performance indicators. In cycle II, the average score for mathematics learning outcomes was 74.62% with a classical completeness presentation of 81.48% and the performance indicators had been met, namely 80% of students got a score ≥ 72. Problem-based learning model (Problem Based Instruction) It can also increase students' enthusiasm, motivation to succeed and enthusiasm during learning, based on the results of observations by researchers, partner teachers and observers. From the results of this research, it can be concluded that by implementing a problem-based learning model (Problem Based Instruction) using the guided discovery method with Basic Competencies in calculating the surface area of the Volume of Cubes and Blocks, it can improve the mathematics learning outcomes of class VIII students at SMP Negeri 2 Latambaga.
