This development study aims to 1) create a learning model that fuses e-learning, a mobile app, character building, and outdoor study and 2) determine the effectiveness of the EMCO learning model on student learning outcomes. This study uses a research and development design with the model of Dick and Carey. A product feasibility test is performed by the learning, media, and materials expert validators, and the product’s effectiveness is tested by students. The data analysis includes descriptive statistics to determine the product feasibility and an independent sample t-test to determine the effectiveness of the learning model. The results of the expert validation show that the EMCO model is in the very good category and does not need revision. The EMCO model has a learning syntax with four phases: LKPD (student worksheet), assessment instrument, learning media, and teaching materials. Results indicate that the EMCO learning model is effective in improving geography learning outcomes. The model has the advantages of 1) effective and innovative material delivery; 2) easy-to-use navigation keys to access the material; 3) attractive design; 4) availability of CBT (computer-based test); and 5) online learning media that can be accessed anytime, anywhere, and under any conditions. The research has a positive impact on students and is able to transform them into 21<sup>st</sup>-century learning agents.
