There are numerous examples suggesting that multimedia can be used to enhance e-learning. However, creating multimedia content can be time-consuming and/or expensive, which is why we chose to study the effect of multimedia in the Assistment project (a web-based system that both assists students' learning and assesses their abilities in order to help them prepare for the Massachusetts Comprehensive Assessment System (MCAS) Math test). We performed a randomized controlled experiment where 50% of the students were assigned (after a pre-test) to a condition with multimedia content, while the other 50% of students received the already existing content that did not have multimedia. While the results showed that there was no statistically significant difference between the two groups, this study discusses several possible reasons for that and proposes a number of areas of study and testing that would clarify and build on this work.
