Modality and cueing in multimedia learning: Examining cognitive and perceptual explanations for the modality effect

The purpose of this study was to investigate the effects of modality (written text vs. spoken text) and visual cueing (low cueing vs. high cueing) on the learning and mental effort of participants studying a computer-based static diagram at their own pace. Participants were randomly assigned to four versions of the computer-based materials formed into a 2x2 factorial design by crossing modality with cueing. The results revealed a reverse modality effect, wherein participants studying written text outperformed those studying spoken text on tests of free recall, matching, comprehension, and spatial recall, but not mental effort. Information cueing did not significantly affect either performance or mental effort. These findings are discussed in the context of two popular explanations of the modality effect: the cognitive resources explanation and the perceptual resources explanation. The results were best explained from a perceptual resources viewpoint.

The effects of verbally redundant information on student learning: An instance of reverse redundancy

Abstract This study aimed to examine the effects of redundant on-screen text on student learning outcomes (i.e. comprehension, matching, spatial labeling, and diagram reconstruction) when learning from multimedia instruction. An interactive, learner-controlled multimedia material was developed to teach the points of articulation used to describe human speech sounds. Participants included 137 undergraduate students from a large southwestern university in the U.S. who were randomly assigned to one of two treatment conditions: (1) an audio only treatment where audio descriptions of each point of articulation were provided, (2) an audio with text label treatment where audio descriptions of each point of articulation plus redundant text labels were provided. The results showed that having redundant on-screen text with spoken information was helpful for student learning. Overall, results confirm an instance of the reverse redundancy effect when instructional material is complex; redundant on-screen text is short; and learners have control over the pace of instruction.

The reverse modality effect: Examining student learning from interactive computer‐based instruction

The purpose of this study was to explore the effects of modality on learning from multimedia instruction. This study utilized a factorial between-subject design to examine the effects of modality on student learning outcomes, study patterns and mental effort. An interactive computer-presented diagram was developed to teach the places of articulation in human speech. A total of 151 undergraduate students at a large southwestern university in USA participated in this study. Participants were randomly assigned to one of two modality conditions (ie, written text and spoken text). Data were obtained through surveys, student logs and knowledge tests. Findings revealed a reverse modality effect, wherein participants who studied with written text outperformed those who studied with spoken text. [ABSTRACT FROM AUTHOR]
