Abstract
Abstract The purpose of this study was to investigate the effect of the implementation of the Causalitic-learning Model (CLM) on Problem-solving Ability (PSA) in terms of creativity. This study used an untreated control group design with pre-test and post-test. The sampling technique used purposive sampling and obtained students from XI-MIA-3 as the experimental class (11 male and 22 female) and XI-MIA-2 as the control class (14 male and 20 female). The assessment instrument uses 6 items in the essay test in physics. Data analysis used a two-way ANOVA test with a 2 x 2 factorial design. The results show homogeneous data ( F table = 1.75), and normally distributed ( X 2t able = 7.81), for the control class and experimental class, Hypothesis test results, with a significance level of 0.05, obtained Ha (sig.-value 0.01) and Hb (sig.-value 0.01) so that Ha and Hb are accepted, while for Hc (sig.-value 0.80) so Hc is rejected. Conclusion CLM affects PSA, creativity affects PSA, and there is no effect on the interaction between CLM and creativity on PSA. It is recommended to improve students’ PSA through CLM and or the development of student creativity.
