Abstract
Geometry subject that prosecute students to comprehend abstracts things is one of the causesof students’ difficulties in mathematics learning. This study aims to determine the effect ofProblem Posing and Problem Solving learning models with the Scientific Approach to students'adaptive reasoning on plane figure materials. It was conducted at the State Junior High School(SMPN) 4 Magetan, Indonesia. It employed quasi-experimental research methods. Thepopulations were the seventh grade students with a total sample of 64 students who weredivided into 34 students as experimental 1 class and the other as experimental 2 class. Thesimple random sampling method was chosen as the sampling technique. Moreover, normalitytest was the Lilliefors method; homogeneity was the Bartlett test; and t-test for research resultsanalysis. The results revealed that the Problem Posing learning model with the ScientificApproach was better than Problem Solving with the Scientific Approach. It significantlyenhanced students' adaptive reasoning on plane figure materials. The Problem Posing learningmodel with the Scientific Approach provided the needed skills to build knowledge, wherestudents performed the process of observation, clarification, measurement, prediction, andhypotheses. Therefore, the model was appropriate for mathematics learning, especially onplane figure materials to increase students’ adaptive reasoning and achievement.
