This type of research is the development of research. The development model used is the four-D Models that have been reduced. The reduction is carried out include the simplification of the stages of development that stage definition (define), stage design (design) and stage of development (develop), while the deployment phase (desiminate) is not implemented . Subjects were students of class IVA and IVB SDN Banyu Urip VIII / 522 Surabaya with experimental designs Non-Equivalent Control Group. Methods Data collection include validity, observation and achievement test. testing this hypothesis using independent sample t-test. the hypothesis test results learn pretest intended to determine the initial conditions of learning outcomes of an experimental class and control class. While hypothesis test learning outcomes post test is intended to determine whether or not a significant influence on the implementation of the Media Three Dimensions in learning Model student Team Achievement Division on learning outcomes of students of class IV Elementary School . the results showed that 1) the validity of the device developed good category. 2) Practicality learning device category excellent 3) The effectiveness of instructional media in terms of the results of the activity of students in the experimental class shows the percentage is very good, in terms of classical completeness experimental class showed that the percentage of completeness more than the minimum criteria, and the results of hypothesis testing on the pretest showed that no there is a significant difference between the average percentage of experimental class learning with classroom control. While the results of hypothesis testing on the posttest show that the effect of applying Media Three Dimensions in Learning Model STAD against student learning outcomes experimental class is better than the effect of conventional teaching methods on learning outcomes control class. Based on these results it can be concluded that the resulting device eligible to applied to learning because it has to meet three criteria: validity, practicality, and effectiveness.
