The role of interest in learning from scientific text and illustrations: On the distinction between emotional interest and cognitive interest.

A textbook lesson may be made more interesting by promoting emotional interest through adding entertaining text and illustrations or by promoting cognitive interest through adding signals for structural understanding such as summary illustrations with captions. In Experiment 1, skilled readers who read summary text and illustrations about the process of lightning performed worse on retention of important information and on transfer when entertaining text, illustrations, or both were added. In Experiment 2, skilled readers rated entertaining text and illustrations relatively high in emotional interest and low in cognitive interest and rated summary illustrations and text relatively low in emotional interest and high in cognitive interest. The results suggest benefits of cognitive interest over emotional interest for helping students learn scientific explanations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Signaling as a cognitive guide in multimedia learning.

In 3 experiments, students received a short science lesson on how airplanes achieve lift and then were asked to write an explanation (retention test) and to write solutions to 5 problems, such as how to design an airplane to achieve lift more rapidly (transfer test). For some students, the lesson contained signals, including a preview summary paragraph outlining the 3 main steps involved in lift, section headings, and pointer words such as because or as a result. The signaling did not add any additional content information about lift but helped clarify the structure of the passage. Students who received signaling generated significantly more solutions on the transfer test than did students who did not receive signaling when the explanation was presented as printed text (Experiment 1), spoken text (Experiment 2), and spoken text with corresponding animation (Experiment 3). Results are consistent with a knowledge construction view of multimedia learning in which learners seek to build mental models of cause-and-effect systems.

When is an illustration worth ten thousand words?

In 3 experiments, students read expository passages concerning how scientific devices work, which contained either no illustrations (control), static illustrations of the device with labels for each part (parts), static illustrations of the device with labels for each major action (steps), or dynamic illustrations showing the "off" and "on" states of the device along with labels for each part and each major action (parts-and-steps). Results indicated that the parts-and-steps (but not the other) illustrations consistently improved performance on recall of conceptual (but not nonconceptual) information and creative problem solving (but not verbatim retention), and these results were obtained mainly for the low prior-knowledge (rather than the high prior-knowledge) students. The cognitive conditions for effective illustrations in scientific text include appropriate text, tests, illustrations, and learners.

When Static Media Promote Active Learning: Annotated Illustrations Versus Narrated Animations in Multimedia Instruction.

In 4 experiments, students received a lesson consisting of computer-based animation and narration or a lesson consisting of paper-based static diagrams and text. The lessons used the same words and graphics in the paper-based and computer-based versions to explain the process of lightning formation (Experiment 1), how a toilet tank works (Experiment 2), how ocean waves work (Experiment 3), and how a car's braking system works (Experiment 4). On subsequent retention and transfer tests, the paper group performed significantly better than the computer group on 4 of 8 comparisons, and there was no significant difference on the rest. These results support the static media hypothesis, in which static illustrations with printed text reduce extraneous processing and promote germane processing as compared with narrated animations.

Cognitive constraints on multimedia learning: When presenting more material results in less understanding.

In 4 experiments, college students viewed an animation and listened to concurrent narration explaining the formation of lightning. When students also received concurrent on-screen text that summarized (Experiment 1) or duplicated (Experiment 2) the narration, they performed worse on tests of retention and transfer than did students who received no on-screen text. This redundancy effect is consistent with a dual-channel theory of multimedia learning in which adding on-screen text can overload the visual information-processing channel, causing learners to split their visual attention between 2 sources. Lower transfer performance also occurred when the authors added interesting but irrelevant details to the narration (Experiment 1) or inserted interesting but conceptually irrelevant video clips within (Experiment 3) or before the presentation (Experiment 4). This coherence effect is consistent with a seductive details hypothesis in which the inserted video and narration prime the activation of inappropriate prior knowledge as the organizing schema for the lesson.

Can student-generated illustrations be worth ten thousand words?

The major purpose of the present study was to determine if reader-generated illustrations are as effective as experimenter-provided illustrations in providing students with the ability to understand scientific explanations. In addition, the authors were interested in replicating work by R. E. Mayer and colleagues (e.g., R. E. Mayer & R. B. Anderson, 1991; R. E. Mayer & J. K. Gallini, 1990) using different texts. The authors found that students with text and illustrations and students who generated their own illustrations performed better on a problem-solving test than students with text only and that there were no significant differences in performance between the former 2 groups.

Systematic thinking fostered by illustrations in scientific text.

In 2 experiments, students who lacked prior knowledge about car mechanics read a passage about vehicle braking systems that either contained labeled illustrations of the systems, illustrations without labels, labels without illustrations, or no labeled illustrations. Students who received passages that contained labeled illustrations of braking systems recalled more explanative than nonexplanative information as compared to control groups, and performed better on problem solving transfer but not on verbatim recognition as compared to control groups. Results support a model of meaningful learning in which illustrations can help readers to focus their attention on explanative information in text and to reorganize the information into useful mental models.

A split-attention effect in multimedia learning: Evidence for dual processing systems in working memory.

Students viewed a computer-generated animation depicting the process of lightning formation (Experiment 1) or the operation of a car's braking system (Experiment 2). In each experiment, students received either concurrent narration describing the major steps (Group AN) or concurrent on-screen text involving the same words and presentation timing (Group AT). Across both experiments, students in Group AN outperformed students in Group AT in recalling the steps in the process on a retention test, in finding named elements in an illustration on a matching test, and in generating correct solutions to problems on a transfer test. Multimedia learners can integrate words and pictures more easily when the words are presented auditorily rather than visually. This split-attention effect is consistent with a dual-processing model of working memory consisting of separate visual and auditory channels.

Varying tutorial modality and interface restriction to maximize transfer in a complex simulation environment.

[Correction Notice: An erratum for this article was reported in Vol 103(2) of Journal of Educational Psychology (see record 2011-10421-001). The name of the author Laura G. Torres was omitted.] In 2 experiments, 241 undergraduates with low domain knowledge viewed a tutorial on how to use Packet Tracer (PT), a computer-networking training simulation developed by the Cisco Networking Academy. Participants were then tested on retention of tutorial content and transfer using PT. Tutorial modality (text, narration, or narration plus text) was varied betweens subjects in both experiments, and simulation interface restriction (restricted or unrestricted) was varied between subjects only in Experiment 1. When PT's interface was unrestricted, students who received the narration tutorial performed better on the transfer task compared with students who received the text tutorial (statistically significant in Experiment 1 but not in Experiment 2). These findings extend the cognitive theory of multimedia learning (Mayer, 2005) by testing modality effects in new contexts and further specifying conditions of its applicability.

Better revision in eight minutes? Prompting first-year college writers to revise globally.

Two experiments examined the relation between revision and task definition among college students in writing courses. In Experiment 1, students prompted to make global revisions to their drafts of college application letters improved their drafts more than students not prompted to make global revisions. Results of Experiment 1 extended results of D. L. Wallace and J. R. Hayes (1991), who found the same effect for students revising text they had not written. In Experiment 2, the treatment did not improve revisions by college students (identified as measured by low SAT verbal scores) who completed the same writing task. Together, results of these 2 experiments suggest that the prompt to revise globally may be effective in helping entry-level college writing students improve their texts (the prompt seems to have encouraged them to make better revisions) but that it is not effective in helping basic-level college writing students revise.

Effects of organizational signals on free recall of expository text.

How is text memory influenced by organizational signaling devices? In Experiments 1 and 2, college students read a text with or without headings, overviews, and summaries; then they did a free recall. When the text's topic structure was simple (Experiment 1), signaling had no effect. When the structure was complex (Experiment 2), signaling affected the distribution of recall of text content and recall organization. Experiment 3 compared recall for texts in which all, half, or none of the topics were signaled. Signaled content was recalled equally well for the half-signaled and fully signaled texts. However, unsignaled content was recalled more poorly for the half-signaled text than for the unsignaled text, suggesting that signals direct processing of text content.

Mnemonic facilitation of learning disabled students' memory for expository prose.

In two experiments, learning disabled adolescents read passages that described North American minerals, using materials that incorporated either mnemonic or nonmnemonic illustrations. In Experiment 1, the students were instructed to remember attribute dichotomies (e.g., hard vs. soft minerals), whereas in Experiment 2, the students had to remember specific attribute values (e.g., Hardness Levels 1–20). In both experiments, students learned significantly more when they studied passages with mnemonic pictures. This was true both on immediate performance tests (Experiments 1 and 2) and following a 1-week delay (Experiment 2). Moreover, in Experiment 2, mnemonic instruction facilitated student's ability to make correct inferences about attribute dichotomies—even though such information was never explicitly presented in the lesson.

Increased interestingness of extraneous details in a multimedia science presentation leads to decreased learning.

In Experiment 1, students received an illustrated booklet, PowerPoint presentation, or narrated animation that explained 6 steps in how a cold virus infects the human body. The material included 6 high-interest details mainly about the role of viruses in sex or death (high group) or 6 low-interest details consisting of facts and health tips about viruses (low group). The low group outperformed the high group across all 3 media on a subsequent test of problem-solving transfer (d = .80) but not retention (d = .05). In Experiment 2, students who studied a PowerPoint lesson explaining the steps in how digestion works performed better on a problem-solving transfer test if the lesson contained 7 low-interest details rather than 7 high-interest details (d = .86), but the groups did not differ on retention (d = .26). In both experiments, as the interestingness of details was increased, student understanding decreased (as measured by transfer). Results are consistent with a cognitive theory of multimedia learning, in which highly interesting details sap processing capacity away from deeper cognitive processing of the core material during learning.

Cognitive principles of multimedia learning: The role of modality and contiguity.

Students viewed a computer animation depicting the process of lightning. In Experiment 1, they concurrently viewed on-screen text presented near the animation or far from the animation, or concurrently listened to a narration. In Experiment 2, they concurrently viewed on-screen text or listened to a narration, viewed on-screen text following or preceding the animation, or listened to a narration following or preceding the animation. Learning was measured by retention, transfer, and matching tests. Experiment 1 revealed a spatial-contiguity effect in which students learned better when visual and verbal materials were physically close. Both experiments revealed a modality effect in which students learned better when verbal input was presented auditorily as speech rather than visually as text. The results support 2 cognitive principles of multimedia learning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Use of analogy in learning scientific concepts.

[Correction Notice: An erratum for this article was reported in Vol 19(5) of Journal of Experimental Psychology: Learning, Memory, and Cognition (see record 2008-10486-001). The captions for Figures 1 and 2 on pp. 979 and 980, respectively, were transposed. The figures and the correct captions are included in the erratum.] Four experiments compared learning of scientific concepts as expressed in either traditional literal form or through an analogy. Comprehension of basic-level details and inferential implications was measured through muliple-choice testing. In Exp 1, literal or analogical renditions were presented in textual form only. In Exp 2, text was accompanied by a dynamic video. In Exp 3, the video and text literal rendition was compared with a text-only analogical rendition. In Exp 4, Ss read only about a familiar domain. Ss consistently answered basic-level questions most accurately when concepts were expressed literally, but answered inferential questions most accurately when concepts were expressed analogically. Analysis of individual differences (Exp 2) indicated that this interaction strongly characterized the conceptual learning of science novices. The results are discussed within the framework of schema induction.

Enhancing the recall of text: Knowledge mapping training promotes implicit transfer.

Spatial–semantic displays, such as knowledge maps, are becoming more prevalent in educational settings (D. R. Dansereau & D. Newbern, 1997). In particular, knowledge maps have been found to be effective communication aids and study devices. Although explicit use of these displays can be effective, it has not been clear whether or not experience with these displays improves the manner in which people interact with other information formats. These experiments were designed to investigate whether mapping training helped people learn from text when not explicitly using a mapping strategy. In Experiment 1, college students trained with knowledge maps recalled more macro-level ideas from two text passages compared with participants who were not given the training. In Experiment 2, training facilitated recall of both macro- and micro-level ideas. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Multimedia Learning in an Interactive Self-Explaining Environment: What Works in the Design of Agent-Based Microworlds?

Students learned about electric motors by asking questions and receiving answers from an on-screen pedagogical agent named Dr. Phyz who stood next to an on-screen drawing of an electric motor. Students performed better on a problem-solving transfer test when Dr. Phyz's explanations were presented as narration rather than on-screen text (Experiment 1), when students were able to ask questions and receive answers interactively rather than receive the same information as a noninteractive multimedia message (Experiments 2a and 2b), and when students were given a prequestion to guide their self-explanations during learning (Experiment 3). Deleting Dr. Phyz's image from the screen had no significant effect on problem-solving transfer performance (Experiment 4). The results are consistent with a cognitive theory of multimedia learning and yield principles for the design of interactive multimedia learning environments.

The effects of age, illustrations, and task variables on the performance of procedural assembly tasks.

Older adults may be disadvantaged in the performance of procedural assembly tasks because of age-related declines in working memory operations. It was hypothesized that adding illustrations to instructional text may lessen age-related performance differences by minimizing processing demands on working memory in the elderly. In the present study, younger and older adults constructed a series of 3-dimensional objects from 3 types of instructions (text only, illustration only, or text and illustrations). Results indicated that instructions consisting of text and illustrations reduced errors in construction for both age groups compared with the other formats. Younger adults, however, outperformed older adults under all instructional format conditions. Measures of spatial and verbal working memory and text comprehension ability accounted for substantial age-related variance across the different format conditions but did not fully account for the age differences observed.
