By the catholicity of Internet and the advances of information technology, more and more people use the e-Learning to do the teaching and learning activities. However, whether using the abundant multimedia learning content can really achieve better learning performance? This study tries to use the information processing theory to discuss the impact of fitness bwteeen learner¡¦s different information processing abilities and content¡¦s medium types on cognitive load and learning performance. That is if learner¡¦s information processing abilities can fit with content medium types would result better learning performance. We found that firstly, the diversity of learners¡¦ individual information processing abilities has no impact to the cognitive load. Secondly, the different content medium types with the same quantity of media content also have no impact to the cognitive load. Lastly, the wordy ability learners with wordy content medium type or the phonic ability learners with audio content medium type can lower learner¡¦s cognitive load. It is suggested that educators can apply the results for the adaptive learning. By using information processing ability analysis system to classify learners into wordy ability and phonic ability learners and then give them adaptive content materials according to their own information processing abilities.
