Abstract
This study present an investigation of student^s conceptual understanding, using quasi-experimental method. This study using two type of class, first, an experiment class with 27 students where the ADI method is given and, second, the control class eight 30 students with conventional learning method. Pre-test and post-test are given to take data from both classes, using the essay test about wave concept. The average scores of the conceptual understanding of control class and experiment class is respectively 46.20 and 55.61and the t-test result is tcount > ttable (4.256 >1.673). The result show that there^s a significant impact of ADI learning to the understanding of wave concept. This also supported by the N-gain scores of the class experiment by (0.43) which is in medium category, while the control class is (0.28) which is in low category. ADI is a learning method that emphasizes the scientific argumentation process that can give an positive impact on the student^s understanding on wave concept.
