The Development of Cooperative Type-Based Learning Media of STAD Assisted by Adobe Flash to Improve Spatial Ability of Students in Medan 1 MTs Negeri 1 Model

In innovative learning the teacher must use learning media, because media is one of the factors that support the success of the learning process in the classroom. Through media combined with learning models, it will facilitate a conducive, creative learning process and improve learning efficiency so that learning objectives can be achieved. The purpose of this study is to develop mathematics learning media based on STAD using the Adobe Flash application program to improve students' spatial abilities. The development procedure used is a 4-D procedure. The procedure used is limited to 3-D from 4-D, namely define, design, and develop. The researcher determined the research subjects, namely class VIII-11 MTs Negeri 1 Model Medan. This study resulted in a mathematics learning media that has been declared valid and feasible to be used as a whole as a learning medium by 3 media experts who obtained an average score of 92.7 and 3 material experts who obtained an average score of 103 with each score the maximum validity is 4. For the learning media attractiveness test stated "Very Interesting" by the group test obtaining an average score of 3.8 with each maximum score of attractiveness is 4. While the students' spatial ability test is known the number of students who fulfill the completeness score on when the pre-test was 34%, while at the post-test it was 86%. So it can be concluded that the development of the STAD-based learning media produced was declared feasible and improved the spatial ability of students.
