Abstract
The objective of this research was to investigate the effect of Learning model of STAD geogebra viewed from learning style. This research used the quasi experimental research method with the factorial design of 2 × 3. The population was entirely the students 4thof Mathematics Education Program Ma’arif Institute of Metro Lampung in Academic Year 2015/2016. The samples of the research were taken by using the cluster random sampling technique. The size of the sample was 50 students consisted of 26 students in the first experimental class and 24 students in the control class. The instruments to gather the data of the research were test of learning achievement in mathematics and student learning styles questionnaire. The data was analyzed by using the two-way analysis of variance with unbalanced cells. The conclusionsof thisresearchwere as follows. (1) The cooperative learning model of STAD Geogebra type resulted in a better learning achievement in mathematics than the Powerpoint-assisted direct learning model. (2) Students with visual learning style have the same achievement with students with auditory learning styles. Students with auditory learning style have the same achievement with students with kinesthetic learning styles. Students with visual learning styles have a better academic achievement than students with kinesthetic learning styles. (3) Difference in achievement of each learning method was not consistent with their respective learning styles and differences between individual learning style also was not consistent in each learning method Keywords: geogebra, power point, STAD
