This study aims to: (1) Determine the feasibility of multimedia interactive learning based on CTL in Geography subjects at SMA Negeri 8 Takengon (2) To determine the effectiveness of interactive multimedia learning based on CTL in improving student learning outcomes in Geography subjects at SMA Negeri 8 Takengon. The stages of this research are the needs analysis stage, the planning stage of interactive multimedia learning based on CTL in geography learning (design), the development stage (develop), and the trial stage (validation). The results of this study indicate (1) The test of the geological material expert is in very good qualifications (90.33%), (2) The test of the instructional media expert is in very good qualification (91.56%), (3) The test of the learning design expert is in very good qualifications (94.44%), (4) individual trials are in poor qualifications (74.64%), (5) small group trials are in good qualifications (79.33%), (6) Field trials are in very good qualifications (97.83%). The results of hypothesis testing prove that there are significant differences between student learning outcomes before using CTL-based interactive learning multimedia and those using CTL-based interactive learning multimedia. This is indicated by the results of data processing tcount = 1.97, at the significance level α = 0.05 t table = 1.69. It was concluded that the interactive multimedia learning media based on CTL developed were feasible and effective to improve learning outcomes of Geography at SMA Negeri 8 Takengon.
