As mentioned earlier, according to the Brandon Hall Group, e-Learning programs take an impressive 40-60% less time to finish compared to classroom learning. Additionally, IBM has found that participants learn five times more material in online learning courses using multimedia content than in traditional face-to-face courses.An intriguing argument for the effectiveness of e-learning are the studies on human memory and micro-learning. Humans retain information most effectively in bite-sized portions with multiple repetitions. This is not found in a classroom setting where students are presented with an abundance of information with minimal to no repetitions. E-learning allows employees to learn in a scientifically proven way that is most effective for long-term retention and efficiency. Check out this study for more details.
