The aim of this study was to determine design of mathematical models of teaching materials to improve students’ mathematical connection ability and mathematical disposition in middle school through experimental studies. The design in this study was quasi-experimental with non-equivalent control group type. This study consisted of two phases, the first phase was identify students’ learning obstacle on square and rectangle concepts to obtain the appropriate design of teaching materials, beside that there were internalization of the values or characters expected to appear on students through the teaching materials. Second phase was experiments on the effectiveness and efficiency of mathematical models of teaching materials to improve students’ mathematical connection ability and mathematical disposition. The result of this study are 1) Students’ learning obstacle that have identified was categorized as an epistemological obstacle. 2) The improvement of students’ mathematical connection ability and mathematical disposition who used mathematical teaching materials is better than the students who used conventional learning.
