With the rapid growth of digital education, e-learning has become essential for offering accessible and flexible learning opportunities. This paper investigates strategies to achieve long-term learning outcomes and reduce study time in e-learning. It explores various techniques, including self-testing, spaced repetition, and the serial position effect, tailored to both visual and auditory learners. The study compared the effectiveness of these strategies, revealing that self-testing and spaced repetition improve learning and combat forgetting. However, in this context, the serial position effect did not show a noticeable impact on learning outcomes. [For the full proceedings, see ED665357.]
