Abstract
During the COVID-19 pandemic, all educational institutions conduct learning through distance learning. This makes teachers and students have to adapt to online learning, particularly in bifunctional organic compound course, which requires comprehension at the macroscopic, submicroscopic, and symbolic levels. To improve student^s knowledge, an effective online learning method is required. The RADEC (Read-Answer-Discuss-Explain-Create) model was chosen as the model for bifunctional organic compound lectures. These activities were carried out through 5 stages via online learning, including reading lecture materials, doing pre-learning assignments, doing pre-test, doing discussion, and doing post-test. This lecture was attended by 43 students from Chemistry Education study program. Student^s reading time grew by an average of 2.54 hours, and the actual ability of students can be seen through the value of pre-learning assignments. Pre-test and post-test were given to determine student^s potential abilities. Based on the calculation data shows that the discussion affects increasing the potential ability of students. The improvement of students^ potential abilities is not always the same in each topic, this can be seen from the N-Gain scores on each topic. The N-Gain value in preparation of bifunctional compound and diene reaction topics, showed a very low increase (N-Gain value < 0.3).
