Conclusions: The results showed that there is a significant difference in learning variables and cognitive load between each of the interactive multimedia groups and the video with the educational factor compared to the traditional group, with an error level of 0.05, and these groups performed better in learning variables and cognitive load. It can be said that virtual education based on interactive multimedia and video can be used to increase learning and cognitive load and cause students' academic progress.
