The Effect of Problem Based Learning (PBL) Learning Model on Writing Skills of Experimental Reports on the Properties of Gases in Grade 3 Elementary School Students

This study aims to determine whether or not there was an influence of the  problem based learning (PBL) learning model on the Writing Skills of Experimental Reports on the Nature of Gas Objects for Grade III Students. This research used a quantitative approach. This type of research was a pre-experimental design with the one-group pretest-posttest design method. The sample of this study was 23 students. This research instrument was a test in the form of a description question. The result obtained was the sig value. (2-tailed) (0.00) < 0.05 means Ha was accepted, and Ho was rejected. So it can be concluded that the  problem based learning learning model influenced the availability of writing experimental reports on the nature of gas objects in grade III students.
