The formulation of the problem is whether the word square learning model has a significant effect on PKn learning outcomes of third grade students of SD Negeri Besani Kabupaten Batang. The research hypothesis is the word square learning model can have a significant effect on the learning outcomes of PKn class III SD Negeri Besani Kabupaten Batang. The purpose of the study was to determine the effect of word square learning model on PKn learning outcomes of third grade students of SD Negeri Besani Kabupaten Batang. This type of research is quantitative through experimental research method. True experimental design research is designed with posttest-only control design. The population was students of SD Negeri Besani Kabupaten Batang, the samples were all third grade students and the sampling technique used was non probability sampling with saturated sampling types.

So, it was concluded that the word square learning model affected the learning outcomes of third grade students of SD Negeri Besani Kabupaten Batang. The advice that researchers can convey to elementary school teachers is that learning by using word square learning models can be implemented in the teaching and learning process as a variation of teaching so that it is not monotonous and creates creativity in students and confident in learning.
