Abstract

The creative thinking skills of SDN Kedung Jaya students are still quite low, the average pre-research results are below the KKM which means they are included in the criteria less. There is still no progress in learning models or media that can support the development of creative thinking skills. Therefore, the researcher intends to make a study related to teaching at SDN Kedung Jaya, teaching that is more varied to increase student creativity. Researchers will use teaching with the PjBL model and auxiliary media, namely the multiplication aid board (Baper). Quantitative approach with quasi-experimental method. The quasi-experiment design chosen is nonequivalent control group design. The research was conducted at SDN Kedung Jaya class III with a population used by researchers as many as 80 students then the sample taken was 40 using Purposive Sampling Technique. Data collection techniques using questionnaire, documentation and tests (pre-test, post-test). The results of the t test showed an influence on students' creative thinking skills showing a significance level of 0.001 <0.05. This shows that there is a significant effect of the application of the PjBL Model with a Lattice Method approach assisted by Baper Board Media to improve students' creative thinking skills in mathematics subjects. Based on the results, there was a significant difference in effectiveness between the experimental group and the control group. The experimental group showed better improvement with an N-Gain score of 0.60, which means they experienced a 60% increase in score from the initial score. This improvement was classified in the “Moderately Effective” category. On the other hand, the control group only achieved an N-Gain score of 0.355 which shows an increase of 35.5% and is classified in the “Ineffective” category. Based on the results of the study, classroom teachers should focus more on developing more varied learning methods and using innovative learning media.
