Two experiments examined visual attention distribution in learning from text and pictures. Participants watched a 16-step multimedia instruction on the formation of lightning. In Experiment 1 (N = 90) the instruction was system-paced (fast, medium, slow pace), while it was self-paced in Experiment 2 (N = 31). In both experiments the text modality was varied (written, spoken). During learning, the participants’ eye movements were recorded. Results from both experiments revealed that learners spent more time studying the visualizations with spoken text than those with written text. In written text conditions learners consistently started reading before alternating between text and visualization; moreover, they spent more time reading the text than inspecting the visualizations. While in Experiment 1 additional time that was made available in conditions with a slow or medium instruction pace was spent inspecting visualizations, in Experiment 2 longer learning times resulted from reading the text more intensively. With respect to learning outcomes (retention, transfer, and visual memory) Experiment 1 revealed an effect of text modality for visual memory only. In Experiment 2 no modality effects were found. Instruction pace was hardly related to learning outcomes. Overall, the results confirm prior findings suggesting that the distribution of visual attention in multimedia learning is largely guided by the text.  相似文献

Two experiments were conducted to investigate how individuals with persistent pain would respond to instructional materials designed to promote the modality and redundancy effects. It was predicted that persistent pain would reduce the positive impact of narrated text due to reduced working memory capacity. One hundred thirty-seven full-time teachers from six schools in Australia participated in the study. Pain and pain-free participants were identified and matched through a demographics questionnaire before being randomly assigned to selected instructional formats. In both experiments, participants viewed system-paced multimedia presentations depicting how lightning works. In Experiment 1, it was found that for pain-free participants, illustrations plus narrated text led to significantly higher learning outcomes than illustrations plus written text (a modality effect). However, for pain participants, no advantage was found for the illustrations plus narrated text format. In Experiment 2, it was found that for pain-free participants, illustrations plus narrated text led to significantly higher learning outcomes than illustrations plus narrated text plus identical written text (a redundancy effect). For pain participants, a reverse effect was found, suggesting that the replicated written text format was not redundant but beneficial for these individuals. Furthermore, despite low scores on standardized pain measures, individuals with persistent pain achieved significantly lower learning outcomes than pain-free participants in both experiments. It was concluded that clinically low levels of pain could significantly interfere with information retention and transference. For individuals with persistent pain, the use of narrated explanatory text could be a disadvantage due to its transitory nature.  相似文献

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.  相似文献

In an example of the redundancy effect, learning is inhibited when written and spoken text containing the same information is presented simultaneously rather than in written or spoken form alone. The current research was designed to investigate whether the redundancy effect applied to reading comprehension in English as a foreign language (EFL) by comparing two instructional formats, written presentation only and written presentation concurrent with verbatim spoken presentation. Participants were in their first year of tertiary education. Examination of translation scores, subjective mental load ratings, and free recall performance indicated that simultaneous presentations rendered text comprehension less effective both at a lexical level and at the level of text comprehension compared with written presentation only.  相似文献

The finding that under split-attention conditions students learn more from a picture and spoken text than from a picture and written text (ie, the modality effect) has consistently been found in many types of computer-assisted multimedia learning environments. Using 58 fifth-grade and sixth-grade elementary school children as participants, we investigated whether the modality effect can also be found in a mobile learning environment (MLE) on plants' leaf morphology, in which students had to learn by integrating information from text and real plants in the physical environment. A single factor experimental design was used to examine the hypothesis that students in a mixed-mode condition with real plants and spoken text (STP condition) would pay more attention to the real plants, and achieve higher performance on retention, comprehension, and transfer tests than the single-mode condition with real plants and written text (WTP condition). Whereas we found that participants in the STP condition paid more attention to observing the plants, and achieved a higher score on the transfer test than participants in the WTP condition, no differences were found between the conditions for retention and comprehension test performance.  相似文献

Spoken words have always been an important component of traditional instruction. With the development of modern educational technology tools, spoken text more often replaces or supplements written or on-screen textual representations. However, there could be a cognitive load cost involved in this trend, as spoken words can have both benefits and disadvantages based on essential characteristics of our cognitive architecture. This paper analyzes factors that might moderate the effectiveness of using spoken text in instruction by reviewing relevant studies in multimedia learning and considering cognitive load consequences of the transiency of spoken information. However, in contrast to earlier studies that considered spoken words in the context of a specific cognitive load effect, this paper provides a framework for evaluating potential instructional benefits of spoken text by analyzing various instructional situations depending on whether spoken text is used together with pictures and written text, and taking into account relations between presented sources of information.  相似文献

Adding pictures to a text is very common in today’s education and might be especially beneficial for elementary school children, whose abilities to read and understand pure text have not yet been fully developed. Our study examined whether adding pictures supports learning of a biology text in fourth grade and whether the text modality (spoken or written) plays a role. Results indicate that overall, pictures enhanced learning but that the text should be spoken rather than written. These results are in line with instructional design principles derived from common multimedia learning theories. In addition, for elementary school children, it might be advisable to read texts out to the children. Reading by themselves and looking at pictures might overload children’s cognitive capacities and especially their visual channel. In this case, text and pictures would not be integrated into one coherent mental model, and effective learning would not take place.  相似文献

When using modern educational technology, some forms of instruction are inherently transient in that previous information usually disappears to be replaced by current information. Instructional animations and spoken text provide examples. The effects of transience due to the use of animation-based instructions (Experiment 1) and spoken information under audio-visual conditions (Experiment 2) were explored in a cognitive load theory framework. It was hypothesized that for transient information presented in short sections, animations would be superior to static graphics, due to our innate ability to learn by observing. For transient information in long sections, animations should lose their superiority over static graphics, due to working memory overload associated with large amounts of transient information. Similarly, the modality effect under which audio-visual information is superior to visual only information should be obtainable using short segments but disappear or reverse using longer segments due to the working memory consequences of long, transient, auditory information. Results supported the hypotheses. The use of educational technology that results in the transformation of permanent into transitory information needs to be carefully assessed.  相似文献

Two experiments investigated how signals foster learning from text and diagrams by examining the relationship between visual attention and learning outcomes. In Experiment 1 (N = 55) students learned about the circulatory heart system from a multimedia lesson either with or without signals highlighting text–diagram correspondences. Results showed that students learning with signals attended to signaled (but not to non-signaled) information more frequently and earlier during learning; these changes in visual attention could explain better performance in answering text–diagram-integration questions. Experiment 2 (N = 78) replicated these findings with respect to early attention on signaled diagram elements and learning outcomes; in addition, a third condition was investigated, where signals highlighted diagram elements that did not match the text. Results showed that mismatched signals guided attention only initially, whereas later on students attended more to information that corresponded to the text. Mismatched signals had no effect on learning outcomes. Taken together, the results suggest that signals aid learning by highlighting specific text–diagram correspondences and not by amplifying diagram processing more generally.  相似文献

The purpose of this study was to examine the redundancy effects obtained when spoken information was duplicated in writing during the learning of a multimedia document. Documents consisting of diagrams and spoken information on the development of memory models were presented to three groups of students. In the first group, no written text was presented. In the second, written sentences redundant with the spoken information were progressively presented on the screen while in the third group, these written sentences were presented together. The results show that whatever the type of text presentation (sequential or static), the duplication of information in the written mode led to a substantial impairment in subsequent retention and transfer tests as well as in a task in which the memorization of diagrams was evaluated. This last result supports the hypothesis that the visual channel is overloaded as the cognitive theory of multimedia learning suggests.  相似文献

Animated models use animations and explanations to teach how a problem is solved and why particular problem-solving methods are chosen. Often spoken explanations are proposed to accompany animations in order to prevent overloading the visual channel (i.e., the modality effect). In this study we adopt the hypothesis that the inferior performance of written text compared to spoken text is due to the fact that written text receives less attention and, consequently, less effortful processing. In a 2 × 2 factorial experiment (N = 96) with the factors modality (written, spoken) and reflection (reflection prompts, no reflection prompts) the hypothesis is tested that prompted reflection requires learners to explicitly attend to written explanations and carefully process them, thus yielding higher transfer performance, whereas for spoken explanations prompted reflection would have no effect on transfer performance. The results indeed showed the hypothesized interaction between modality and reflection prompts. They suggest that the modality effect can be compensated for when learners explicitly attend to the information and effortfully process it. This has implications for learning situations in which spoken explanations are no option, such as education for the hearing-impaired.  相似文献

The present paper reports on an empirical study which investigated learning with text and animations in the science classroom. In a 2?×?2 design the presence of multimedia learning material instruction (text only vs. text + animations) as well as the modality of the explanatory text (spoken vs. written) were tested. Prior to learning, students’ motivation to learn was assessed as a continuous factor. Recall and transfer were assessed immediately after learning. The results show better recall of information for learners with multimedia materials, providing the animations were accompanied by spoken text. However, in contrast to the positive effects of domain-specific motivation this multimedia effect was not evident for transfer. The effects of multimedia design were independent of motivation. Implications for future studies are discussed.  相似文献

The term ‘modality effect’ in multimedia learning means that students learn better from pictures combined with spoken rather than written text. The most prominent explanations refer to the split attention between visual text reading and picture observation which could affect transfer of information into working memory, maintenance of information in working memory or the effective size of working memory. The assumption of a continuous need for split attention is questionable, however. Learners can keep pictorial information in working memory, when they have seen the picture before, especially if they have higher prior knowledge. Instead of suffering from a permanent split attention, learners frequently show tendencies to simply ignore pictures. This suggests guiding learners towards picture analysis by picture-related text paragraphs. We assume that these paragraphs are associated with stronger modality effects than content-related paragraphs, especially if the pictures are new to learners. These assumptions were tested in an experiment with 120 students learning about volcanism from illustrated text consisting of segments each including a content-related paragraph followed by a picture-related paragraph describing the accompanying visualization. Content-related and picture-related paragraphs were presented as visual or auditory texts leading to 2x2 conditions of text presentation. Picture novelty was manipulated by presenting a picture throughout the whole segment or only when the picture-related paragraph was read. As expected, picture-related paragraphs were associated with stronger modality effects than content-related paragraphs if picture novelty is high. The distinction between different kinds of paragraphs seems to be important for the prediction of modality effects.  相似文献

Paper-and-pencil learning and testing are gradually shifting to computerized environments. Cognitive and metacognitive researchers find screen inferiority compared to paper in effort regulation, test performance, and extent of overconfidence, in some cases, with unknown differentiating factors. Notably, these studies used reading comprehension tasks involving lengthy texts, which confound technology-related and cognitive factors. We hypothesized that the medium provides a contextual cue which leads to shallower processing on screen regardless of text length, particularly when task characteristics hint that shallow processing is legitimate. To test this hypothesis, we used briefly phrased yet challenging problems for solving on screen or on paper. In Experiment 1, the time frame for solving the problems was manipulated. As with lengthy texts, only time pressure resulted in screen inferiority. In Experiment 2, under a loose time frame, the same problems were now framed as a preliminary task performed before a main problem-solving task. Only the initial task, with reduced perceived importance, revealed screen inferiority similarly to time pressure. In Experiment 3, we replicated Experiment 1's time frame manipulation, using a problem-solving task which involved reading only three isolated words. Screen inferiority in overconfidence was found again only under time pressure. The results suggest that metacognitive processes are sensitive to contextual cues that hint at the expected depth of processing, regardless of the reading burden involved.  相似文献

Based on cognitive load theory and the transient information effect, this paper investigated the modality effect while interpreting a contour map. The length and complexity of auditory and visual text instructions were manipulated. Experiment 1 indicated that longer audio text information within a presentation was inferior to the equivalent longer visual text information demonstrating a reversal of the modality effect due to transient information imposing a heavy working memory load. However, the expected modality effect was not obtained from the equivalent shorter auditory text presentation compared to shorter visual text information. It was hypothesised that the shorter text still contained too much auditory information for working memory to readily process. Experiment 2 further decreased the shorter auditory text information which then resulted in a traditional modality effect including a modality by text length interaction in which shorter, audio-visual information was better than visual only information but longer, audio-visual information was worse than visual only information.  相似文献

In two experiments, eye tracking was used to investigate whether learners construct a mental representation during learning that integrates information from text and pictures. The experimental groups received inconsistent text-picture information on one or two pages of the learning materials. The control groups received only consistent text-picture information. It was expected that learners of the experimental groups should have difficulties in integrating text-picture information when faced with the inconsistencies. This should be reflected in their gaze behavior. Experiment 1 (N = 51) and Experiment 2 (N = 45) confirmed that assumption for several eye tracking variables. Regarding learning outcomes, only in Experiment 1 worse performance of the experimental group was observed. Furthermore, Experiment 2 revealed that the majority of learners did not remember the inconsistency between text and picture when asked for it after learning. In sum, the results add to our understanding about the cognitive processes underlying multimedia learning.  相似文献

The study examined whether the modality effect is caused by either high visuo-spatial load or a lack of temporal contiguity when processing written text and pictures. Students (N = 147) viewed pictures on the development of tornados, which were accompanied by either spoken or written explanations presented simultaneously with, before, or after the pictures. For verbal recall no modality effect was observed, whereas for transfer the influence of modality varied as a function of phonological working memory capacity. For pictorial recall the results showed a modality effect that was limited to simultaneous presentation, apparently in line with the temporal contiguity explanation. However, spoken simultaneous presentations were not superior to spoken sequential presentations, which contradicts the temporal contiguity explanation for the modality effect. Rather, it seems as if learners with simultaneous presentation of written text and picture concentrated more on the text and ignored the pictures, resulting in worse pictorial recall.  相似文献

This study investigated the segmenting and modality principles in instructional animation. Two segmentation conditions (active pause vs. passive pause) were presented in combination with two modality conditions (written text vs. spoken text). The results showed that the significant effect was found in relation to segmentation conditions, whereas the modality effect was not found. The groups with embedded questions (ie, active pause) between segments outperformed pause‐only groups (ie, passive pause) on both recall and transfer tests regardless of the mode of text. The findings of the study imply that a stimulus (eg, testing occasion) would be more effective than only pauses between segments.  相似文献

Previous research investigating the encoding, encoding-plus-storage, and extermal-storage functions of note taking has failed to equate processing opportunities among the groups. The present studies did so by having the encoding group take notes on two occasions without review, the encoding-plus-storage group take notes one time and review notes the next, and the external-storage group twice review a set of borrowed notes. Three forms of note taking were used: conventional, and note taking on skeletal and matrix frameworks. In both Experiment 1, involving lecture learning, and Experiment 2, involving text learning, an advantage was found for the encoding-plus-storage function on tests involving factual-recall and recognition performance but not on tests measuring higher-order performance. With respect to note-taking forms, no advantage existed for any form when information was acquired from lecture. When text material was used there was some advantage for conventional notes and a clear advantage for not taking notes at all, but instead twice reading the material. These findings were explained relative to observed note-taking behaviors, the opportunity for review, and the processing demands proposed by the combination of reading and note taking, particularly when notes must be classified into an existing framework.  相似文献
