1) The document discusses how different multimedia design principles like modality, redundancy, and segmenting can affect the situational interest of adult learners. 2) An experiment tested the effects of modality (narration vs text) and redundancy (repeating information) on triggered and maintained situational interest. Modality and redundancy had a significant effect on triggered and maintained interest. 3) Analysis of variance tests found that multimedia design had a significant effect on triggered and maintained interest but not on learner achievement. Combining narration and text led to the highest maintained interest levels.
