The results of three meta-analyses show that the effectiveness of learning from animations, when compared to learning from static pictures, is rather limited. A recent re-analysis of one of these meta-analyses, however, supports that learning from animations is considerably more effective than learning from static pictures if the specifics of the displayed changes need to be learned. In order to further validate this finding as well as to clarify the educational strengths and weaknesses of animations and static pictures, an experimental study with three groups was conducted. Overall, 88 university students participated in the study. One group of learners (n?=?30) watched a single picture of a gear mechanism, one group of learners (n?=?28) watched four pictures, and one group of learners (n?=?30) watched an animation. All groups had to identify specific motions and spatial arrangements covered by the gear mechanism. While learners who watched the animation exhibited the best performance with respect to the identification of motions, learners who watched the pictures showed the best performance with respect to the identification of spatial arrangements. The effect sizes are large. The results of the study help to clarify when animations and when static pictures are most suitable for learning.

Computer-based multimedia learning environments make it possible to present interactive animated pictures, which can be manipulated for active exploratory learning and which allow the dynamic behavior of complex subject matter to be displayed. Due to the large range of possibilities for exploratory interaction, such learning environments seem well suited for co-operative learning in which different learners analyse the presented subject matter from different perspectives. This paper first describes a theoretical framework for learning from texts and pictures together with an analysis of possible effects of animation and interactivity on knowledge acquisition. It then presents two empirical studies in which knowledge acquisition from interactive animated pictures was compared with knowledge acquisition from static pictures under the conditions of individual learning (Study I) and of cooperative learning (Study II). In Study I, learning with interactive animated pictures resulted in a superior encoding of detail information, but did not facilitate performance of mental simulation tasks. In Study II, learning with interactive animated pictures resulted both in inferior encoding of detail information and poorer results in mental simulations. These findings and the analysis of discourse protocols of subjects’ co-operation suggest that exploratory learning with interactive animated pictures is associated with extraneous cognitive load and that this load can be further increased by the co-ordination demands of co-operative learning. Although animated pictures may provide external support for mental simulations, they do not appear to be generally beneficial for learning, because they can prevent individuals from performing relevant cognitive processes.  相似文献

In a 2 × 2 design, we examined the role of visual cognitive style in two multimedia-based learning environments (text plus static pictures/animations). A statistically significant interaction was obtained for deeper comprehension: Highly developed visualizers (HDV) who learned with static pictures performed better than HDV who learned with animations, and less developed visualizers (LDV) performed the same with static pictures or animations.For factual knowledge, there was a main effect in favor of HDV. Subsequent tests revealed that HDV outperformed LDV only when learning from static pictures, but not when studying animations. There were no overall differences between animations and static pictures. The assumption is made that HDV benefit from their cognitive style when they have to construct a mental animation from static pictures.Concluding, we did not find any rationale for converting static pictures to animations — HDV learned better with static pictures, while for LDV, it made no difference.  相似文献

As follow-up to an initial study phase, both generative learning activities and retrieval practice can substantially enhance learning, but via different functions. Generative activities are theorized to mainly serve the function of constructing coherent mental representations of the learning content that are well integrated with prior knowledge, whereas retrieval practice is theorized to mainly serve the function of consolidating learners’ mental representations in memory. In view of these complementing functions, the present study investigated whether the sequence of these activities matters. In an experiment with N = 158 university students, we varied the sequence of generative learning and retrieval practice after an initial study phase. We found that the retrieval-before-generation sequence yielded better retention and reduced cognitive load during both types of activities. We conclude that although it might seem counterintuitive, engaging learners in retrieval practice before engaging them in generative learning can be more beneficial than vice versa.  相似文献

Three experiments with students from 7th and 8th grade were performed to investigate the effects of decorative pictures in learning as compared to instructional pictures. Pictures were considered as instructional, when they were primarily informative, and as decorative, when they were primarily aesthetically appealing. The experiments investigated, whether and to what extent decorative pictures affect the learner’s distribution of attention, whether they have an effect on the affective and motivational state and whether they affect the learning outcomes. The first experiment indicated with eye-tracking methodology that decorative pictures receive only a bit initial attention as part of the learner’s initial orientation and are largely ignored afterwards, which suggests that they have only a minor distracting effect if any. The second experiment showed that despite the small amount of attention they receive, decorative pictures seem to induce better mood, alertness and calmness with learners. The third experiment indicated that decorative pictures did not intensify students’ situational interest, but reduced perceived difficulty of the learning material. Regarding outcomes of learning, decorative pictures were altogether neither harmful nor beneficial for learning. However, they moderated the beneficial effect of instructional pictures––in essence: the multimedia effect. The moderating effect was especially pronounced when learners had lower prior knowledge. The findings are discussed from the perspective of cognitive, affective and motivational psychology. Perspectives of further research are pointed out.  相似文献

Animations may facilitate learning by providing external support for visual–spatial mental processing. Facilitation is challenged by findings that demonstrate involvement of spatial abilities in learning from animations, because this involvement indicates active internal visual–spatial processing. In the present study, learners attended to a system-paced multimedia presentation in which a verbal–auditory explanation was concurrently synchronized either with animation, with static core pictures, or with enriched static pictures that showed additional intermediate steps and arrows indicating motion. Results demonstrated better learning success with animations and with enriched static pictures than with static pictures. Spatial abilities were not substantively related to learning success with animations or with static pictures, but they played a crucial role for learning success with enriched static pictures. It is concluded that active visual–spatial processing was recruited with enriched static pictures. With animations, learning was truly facilitated by external support for visual–spatial mental processing.  相似文献

This study explored the effects of prior knowledge (high vs. low; HPK and LPK) and concept-map structure (hierarchical vs. network; HS and NS) on disorientation, cognitive load, and learning from non-linear documents on “the infection process of a retrograde virus (HIV)”. Participants in the study were 24 adults. Overall subjective ratings of disorientation and cognitive load, as well as detailed analysis of eye movement and navigation data were used. The results showed that LPK learners gained equal factual knowledge from the HS and NS concept maps, gained more conceptual knowledge from the HS concept map, and had to invest less mental effort in the posttest after learning with the HS concept map. On the other hand, HPK learners gained more factual knowledge from the HS concept map than from the NS concept map, and gained equal conceptual knowledge from both concept-map structures. Also, LPK learners experienced higher disorientation during learning with the NS concept map than the HS map, whereas no differential effect of concept-map structure was found for HPK learners. Both LPK and HPK learners invested less mental effort in processing the HS concept map. The eye tracking and navigation data provided more detailed insight into these findings.  相似文献

The present study investigated the influence of experimentally induced emotions (positive, neutral, negative) on learning with multimedia instruction with N = 75 university students. In order to provide sound explanations about how emotional state might impact learning, measures of motivation, cognitive load, and attentional processes (eye tracking) were integrated. Results showed that while emotions did not influence retention, emotions did influence outcomes of the comprehension and transfer test. Specifically, a facilitating effect of an induced negative emotional state on learning outcomes was observed, which could be attributed to a more focused and detailed information processing. In contrast, an induced positive emotional state had a suppressing effect on learning outcomes since learners were distracted from the learning materials by their emotions. Motivational measures were not influenced by learners' different emotional states, but overall, controlled motivation increased and autonomous motivation decreased during learning. In sum, the learners' emotional state should be considered in learning research as an important predictor for learning success.  相似文献

The purpose of this study was to investigate the impacts of visual cues and different types of self-explanation prompts on learning, cognitive load, and intrinsic motivation in an interactive multimedia environment that was designed to deliver a computer-based lesson about the human cardiovascular system. A total of 126 college students were randomly assigned in equal numbers (N?=?21) to one of the six conditions in a 2?×?3 factorial design with visual cueing (cueing vs. no cueing) and type of self-explanation prompts (prediction prompts vs. reflection prompts vs. no prompts) as the between-subjects factors. The results revealed that (a) participants presented with cued animations had significantly higher learning outcome scores than their peers who viewed uncued animations, and (b) cognitive load and intrinsic motivation had different impacts on learning outcomes due to the moderation effect of cueing. The results suggest that the cues may not only enhance learning, but also indirectly impact learning, cognitive load, and intrinsic motivation.  相似文献

We tested key predictions of a theoretical model positing that confusion, which accompanies a state of cognitive disequilibrium that is triggered by contradictions, conflicts, anomalies, erroneous information, and other discrepant events, can be beneficial to learning if appropriately induced, regulated, and resolved. Hypotheses of the model were tested in two experiments where learners engaged in trialogues on scientific reasoning concepts in a simulated collaborative learning session with animated agents playing the role of a tutor and a peer student. Confusion was experimentally induced via a contradictory-information manipulation involving the animated agents expressing incorrect and/or contradictory opinions and asking the (human) learners to decide which opinion had more scientific merit. The results indicated that self-reports of confusion were largely insensitive to the manipulations. However, confusion was manifested by more objective measures that inferred confusion on the basis of learners’ responses immediately following contradictions. Furthermore, whereas the contradictions had no effect on learning when learners were not confused by the manipulations, performance on multiple-choice posttests and on transfer tests was substantially higher when the contradictions were successful in confusing learners. Theoretical and applied implications are discussed.  相似文献

GearSketch is a learning environment for the gears domain, aimed at students in the final years of primary school. It is designed for use with a touchscreen device and is based on ideas from drawing-based learning and research on cognitive tutors. At the heart of GearSketch is a domain model that is used to transform learners’ strokes into gears and chains, animate the turning of the gears and check whether learners’ solutions to practice problems satisfy the given constraints. Additionally, this domain model is the basis for GearSketch’s learner model and item generation an selection mechanisms. The learner model is used to track learners’ knowledge and adaptively select items as they progress through the practice problems. Two experimental evaluation studies show that GearSketch’s interface and animations lead to improved learning outcomes, but that its adaptive features do not significantly affect posttest results.  相似文献

The effectiveness and efficiency of individual versus collaborative learning was investigated as a function of instructional format among 140 high school students in the domain of biology. The instructional format either emphasized worked examples, which needed to be studied or the equivalent problems, which needed to be solved. Because problem solving imposes a higher cognitive load for novices than does studying worked examples it was hypothesized that learning by solving problems would lead to better learning outcomes (effectiveness) and be more efficient for collaborative learners, whereas learning by studying worked examples would lead to better learning outcomes and be more efficient for individual learners. The results supported these crossover interaction hypothesis. Consequences of the findings for the design of individual and collaborative learning environments are discussed.  相似文献

New technologies enable flexible combinations of text and interactive or non-interactive pictures. The aim of the present study was to investigate (a) whether adding pictures to texts is generally beneficial for learning or whether it can also have detrimental effects, (b) how interactivity of pictures affects learning, (c) whether the visualization format of pictures affects the structure of the learner's mental model, and (d) whether the visualization format modifies the effects of interactivity. One hundred university students were randomly assigned to five groups. In four groups, a text about the different daytimes and days on the earth was combined with interactive or non-interactive pictures of different visualization formats. In the fifth group, the text was presented without pictures. According to the results, adding pictures to text was neither beneficial nor harmful for learning. In terms of learning efficiency, however, learning from text only was more successful than learning from text and pictures. Interactivity was beneficial for one learning task, but not for the other task. The visualization format affected participants’ interaction with pictures, but not the learning outcomes; however this effect was not influenced by interactivity. Implications for multimedia design and for further research are pointed out.  相似文献

Multimedia learning environments combine multiple forms of representations like texts, static and animated pictures or graphs. Knowledge acquisition from multiple representations requires that the learner create referential connections between corresponding elements and corresponding structures in different representations. As this process is usually difficult, learners frequently fail to construct coherent mental representations and, thus, do not sufficiently understand the subject matter. This paper analyzes the effects of different kinds of instructional help on the process of coherence formation from multiple representations by learners with different prior knowledge. Three groups of university students with different domain-specific knowledge had to learn a complex subject matter from chemistry using six different forms of representation. In addition, a first group received directive help for coherence formation. A second group received non-directive help, and a third group received no instructional help. Results indicate that directive help is effective for recall performance because of its summarizing and repeating function. Furthermore, learners with different levels of prior knowledge show different reactions when help is given. For learners with insufficient prior knowledge help is not helpful or, in case of recall performance, even harmful. Learners with a medium level of prior knowledge can increase especially their comprehension performance when help is offered, whereas learners with too much prior knowledge seem not to be affected by help.  相似文献

The present study examined the facilitating function of animations for spatial perspective taking. The task demanded to estimate directions to memorized objects in a spatial scene from an imagined position and orientation within the scene. Static pictures which required imagined reorientation of the self were compared to animations showing the reorientation externally. Individual differences in perspective taking ability were considered. Results showed a large effect in favor of animations for reaction times. An aptitude–treatment-interaction was found for accuracy: The relation between perspective taking ability and accuracy in direction estimation was moderated by type of presentation (static pictures vs. animation). Perspective taking ability played a much stronger role in direction estimation accuracy with static pictures than with animations. It is concluded that focused animations can facilitate perspective taking and thereby compensate for low spatial perspective taking ability.  相似文献

Although writing learning protocols is an effective follow-up course work activity, many learners tend to do it in a rather suboptimal way. Hence, we analyzed the effects of instructional support in the form of prompts. The effects of different types of prompts were investigated in an experiment with four conditions: cognitive prompts, metacognitive prompts, a combination of cognitive and metacognitive prompts, or no prompts (N = 84 undergraduate psychology students). We found that the prompts stimulated the elicitation of cognitive and metacognitive learning strategies. The provision of purely metacognitive prompts did not, however, improve learning outcomes. Only the groups who had received cognitive, or a combination of cognitive and metacognitive, prompts learned more than the control group. This effect was mediated by cognitive learning strategies. The learners in the successful groups did not perceive the prompted learning strategies as more helpful than the learners of the group without prompts. It can be concluded that cognitive prompts—alone or in combination with metacognitive prompts—are an effective means to foster learning. However, additional means should be employed in order to convince the learner of the usefulness of such prompts.  相似文献

Transferring one’s knowledge in new situations is usually associated with cognitively demanding processes. The paper explores an approach to facilitating transfer of knowledge by explicitly instructing learners in medium-level generalized but yet domain-connected knowledge structures that are applicable to a broader range of tasks in the domain and could be essential in managing the cognitive load associated with transfer. The paper includes a theoretical analysis of the potential role of the generalized domain knowledge in transfer and an experimental study designed to investigate the effectiveness of explicit instruction in a generalized domain knowledge structure (function–process–structure schema) in technical areas. Forty-nine undergraduate university students with low or no prior knowledge in the domain participated in the randomised 2 (schema-based vs. non-schema-based instruction)?×?2 (general-to-specific vs. specific-to-general knowledge sequences) experiment investigating the effects of these two factors on posttest transfer performance and subjective ratings of learning difficulty (interpreted as indicators of cognitive load). The results indicated a significant (p?<?0.05) main effect of schema-based instruction; a possible trend (p?<?0.1) favouring general-to-specific instructional sequence for posttest test performance; and a significant interaction between the two factors for ratings of difficulty. The paper concludes that (a) transfer within a domain could be facilitated by explicitly instructing learners in generalized domain schemas; (b) general-to-specific approach could possibly be used as a preferred instructional sequence for enhancing transfer; and (c) cognitive load perspective could add some valid arguments to explain the role of generalized domain knowledge in transfer.  相似文献

Educational multi-user virtual environments (MUVEs) have been shown to be effective platforms for situated science inquiry curricula. While researchers find MUVEs to be supportive of collaborative scientific inquiry processes, the complex mix of multi-modal messages present in MUVEs can lead to cognitive overload, with learners unable to effectively process the rich information encountered in virtual space. In this study, we investigated the effect of communication modality on cognitive load and science inquiry learning in students completing a science inquiry curriculum in an educational MUVE. Seventy-eight undergraduate education majors from a large southwestern university participated in this control-treatment study. Significant positive results were found for reducing cognitive load for participants communicating through voice-based chat, although this reduction was not found to influence learning outcomes. We conclude that use of voice-based communication can successfully reduce cognitive load in MUVE-based inquiry curricula.  相似文献

To examine how visual attentional resources are allocated when learning from a complex animation about the cardiovascular system, eye movements were registered in the absence and presence of visual cues. Cognitive processing was assessed using cued retrospective reporting, whereas comprehension and transfer tests measured the quality of the constructed representation. Within the framework of Cognitive Load Theory, visual cues highlighting the subsystems of the heart were hypothesized to guide attention, reduce visual search and extraneous cognitive load, and enhance learning. As predicted, learners looked more often and longer at cued parts. However, we found no effects of cueing on visual search and cognitive load. With respect to cognitive processing, performance differences were found on the number of statements in the learners’ verbal reports. These findings suggest that visual cueing can guide attention in an animation, but other factors are also important in determining the effectiveness of visual cues on learning.  相似文献

Based on a critical re-analysis of cognitive load theory (CLT), Schnotz and Kürschner identified the need for research on more sensitive ways of assessing learner characteristics, both prior to and during instruction, in order to understand learning processes and outcomes. One emergent theme of the papers in this special issue is that the “same” learning environment is differentially demanding and produces different results depending on characteristics of the learners, most importantly their knowledge in the task domain. These findings indicate that to optimize learning outcomes, theories of instructional design and learning need to be more adaptive and reflect the nuances of interactions among learners, tasks, and instructional supports.  相似文献
