To overcome this problem, this study applies the Treffinger learning model, which is known to be effective in developing students’ creative thinking and problem solving skills. This study aims to analyze the effect of Treffinger learning model on learning outcomes of grade X students in Fiqh subjects at MAN 3 Ngawi. This study used a quantitative method with a True Experimental design, which involved a pretest-posttest control group design. The Experimental class was tauhgt with the Treffinger model, while the control class used a conventional learning model.
