摘要：The purposes of this research were to know the validity, practicality, and effectivity of geometrical learning material based on the constructivism to Increase students' mathematic reasoning ability and increasing students'mathematic reasoning ability by using learning material at the grade VIII of SMP Negeri 3 Padangsidimpuan. Type of the research was the development of research by using modification of the 4-D development models. The steps of this research were the defining step, designing step, developing step, and dissaminating step. The experiment was done at the grade VIII students of SMP Negeri 3 Padangsidimpuan. Result of the research Showed that: 1) The validity of geometrical learning material based on the constructivism to Increase students' mathematic reasoning ability at the grade VIII of SMP Negeri 3 Padangsidimpuan was very valid, 2) practicality of geometrical learning material based on the constructivism to Increase students 'mathematic reasoning abilityat the grade VIII of SMP Negeri 3 Padangsidimpuan was practical to be used, 3) geometrical learning material based on the constructivism to Increase students' mathematic reasoning ability at the grade VIII of SMP Negeri 3 Padangsidimpuan was effective, and 4 ) increasing of students' mathematic reasoning ability by using geometrical learning material based on the constructivism at the grade VIII of SMP Negeri 3 Padangsidimpuan was on the medium category.
