Abstract

Abstract: Research has been carried out in Pekanbaru N 12 Middle School from January to March 2019 which aims to determine the implementation of the constructivism approach to science learning in grade VII students of junior high school using the quasi-experimental technique. The sample used in this study is class VII 2 and VII 3, which amount to each class 32 while the population is all students of class VII SMP N Pekanbaru. The instruments used are learning tools in the form of syllabus, learning implementation plans (RPP), student worksheets based on constructivism approaches. The results showed that the LKPD based on the constructivism approach had an effect on learning outcomes indicating that the control class with a pretest average of 30.54, while in the experimental class with an average value of 31.40 with the pretest category in the two classes "Very poor" at interval <34, this shows that at the beginning of learning before learning or treatment is given both classes have a mean that is not much different.
