Effectiveness of loci method to increase mathematics learning achievement of grade 5th elementary school students

Mathematics learning achievement of elementary school students is determined by the learning method used by the teacher. The learning method needed is a method that can help maximize student memory so that students can remember the material well. The Loci method connects certain objects with specific locations so that the individual may easily recall them. The purpose of this study was to empirically test the effectiveness of the loci method on mathematics learning achievement for elementary school students. This experimental research used a quasi-experimental design, with a one-group research design. Six elementary school students participated in this study. Pretest-posttest design with mathematics achievement test and the loci method treatment module were utilized as instruments. Data were analyzed by the paired sample t-test. The results of data analysis found that there is a difference between pre-test and post-test and that the loci approach helps enhance mathematics achievement. The Cohen's d Effect Size test resulted in a score of 77.4%, indicating that the Loci Method is highly effective in boosting mathematics learning achievement for students in elementary school. The implication of this research is that schools are expected to train mathematics teachers to use the loci method to improve students' mathematics learning achievement.
