Virtual reality (VR) is predicted to create a paradigm shift in education and training, but there is little empirical evidence of its educational value. The main objectives of this study were to determine the consequences of adding immersive VR to virtual learning simulations, and to investigate whether the principles of multimedia learning generalize to immersive VR. Furthermore, electroencephalogram (EEG) was used to obtain a direct measure of cognitive processing during learning. A sample of 52 university students participated in a 2 × 2 experimental cross-panel design wherein students learned from a science simulation via a desktop display (PC) or a head-mounted display (VR); and the simulations contained on-screen text or on-screen text with narration. Across both text versions, students reported being more present in the VR condition (d = 1.30); but they learned less (d = 0.80), and had significantly higher cognitive load based on the EEG measure (d = 0.59). In spite of its motivating properties (as reflected in presence ratings), learning science in VR may overload and distract the learner (as reflected in EEG measures of cognitive load), resulting in less opportunity to build learning outcomes (as reflected in poorer learning outcome test performance). 相似文献

This study demonstrated that the modality principle applies to multimedia learning of regular science lessons in school settings. In the first field experiment, 27 Dutch secondary school students (age 16–17) received a self-paced, web-based multimedia lesson in biology. Students who received lessons containing illustrations and narration performed better on subsequent transfer tests than did students who received lessons containing illustrations and on-screen text. In the second field experiment, 55 Dutch secondary school students (age 16–17) received similar multimedia programs that allowed more self-pacing and required students to record the time to learn. The illustrations-and-narration group outperformed the illustrations-and-text group on subsequent transfer tests for students who required less time to learn but not for students who required more time to learn. The interaction of learning time spent with modality of presentation on post-test scores was studied. Implications for testing of the robustness of cognitive theory of multimedia learning are discussed. 相似文献

本文通过回顾12条基于研究的教学设计原则,说明了如何设计计算机辅助多媒体教学材料来促进学习。首先介绍了多媒体原则(根据五个对照实验得到的中值效应量为d=1.67),其主张在计算机辅助教学中,语词和图像同时呈现的效果比只呈现语词的效果要好。无关认知加工做的是和教学目标无关的事情。为了减少无关认知加工,提出的教学原则有聚焦要义(d=0.70)、标记结构(d=0.46)、控制冗余(d=0.87)、空间邻近(d=0.79)和时间邻近(d=1.30)。基本认知加工的功能在于对基本材料进行心理表征。为了调节基本认知加工,提出的教学原则有分段呈现(d=0.70)、预先准备(d=0.46)和双重通道(d=0.72)。生成认知加工的功能是为了建构材料的意义。为了促进生成认知加工,提出的教学原则有个性化(d=0.79)、人声化(d=0.74)和具身化(d=0.36)。部分原则有边界条件,例如有的原则对新手学习者比对专家学习者更有效。 相似文献

This study examined the impact of redundant on-screen text on learning from an animated PowerPoint presentation, narrated either by a native or a foreign-accented narrator, with no text, summary text, or full text. Participants completed retention and transfer tests and rated the cognitive load induced by the narration and the PowerPoint materials. With a native narrator, participants performed better on transfer with no text than summary text (redundancy effect). The foreign-accented narration was perceived to be more difficult to understand. Transfer performance was worse for accented than native narration with no text, replicating a voice effect. With a foreign-accented narrator, participants performed better on retention with full text than summary text. Full text facilitated decoding of the accented narration at the word level, but it did not facilitate deep processing for knowledge transfer. The results are discussed in the context of cognitive load and the cognitive theory of multimedia learning. 相似文献

This study investigated how the format of verbal instructions in computer simulations and prior knowledge (PK) affected 8th graders' cognitive load (CL) level and achievement in a multimedia learning environment. Although PK was not found to significantly affect student performance and CL level, instruction format was found to impact both. Students who used narrative simulations were found to have a greater CL but also to perform better than those using simulations with on-screen text instructions. However, no significant differences were found between the cognitive efficiency of the two groups. The difficulty of the subject matter and limitations in students' prior content-related knowledge may have increased the intrinsic CL, such that students had difficulty in interpreting the content even if their PK was relatively high. The narrative instructions were more likely than the on-screen text information to reduce the extraneous CL and promote understanding of content. A new measure of cognitive processing is needed to identify the types of CL involved in e-learning and determine the properties of adequate e-learning materials. Finally, the findings of the study are discussed and suggestions for future studies and instructional design are provided. 相似文献

Reading has been regarded as a medium for learning science, revealing the importance of enhancing learners’ reading competence in science education. The critical features of science texts are their multiple representations, such as text and visual elements, which assist the representation of science concepts. A multimedia learning environment can present relevant materials in various formats and help students to process the materials in meaningful ways, for example, by integrating learning materials with relevant prior concepts, and organizing them into a consistent and coherent cognitive structure. However, some issues with multimedia instructional design have been proposed, such as students’ cognitive load and learning motivations. In this study, an augmented reality-based science learning system was developed based on the contiguity principle of multimedia learning in order to promote students’ science learning. Moreover, an experiment was conducted on a natural science course in an elementary school to assess the effectiveness of the implemented system on students’ learning. The experimental results display that the students learning with this approach found made significant gains in their learning achievements and motivations compared to those learning science with conventional multimedia science learning; moreover, their perceptions of extraneous cognitive load were significantly reduced during the learning activity. 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

Multimedia pedagogical agents are on-screen characters that allow users to navigate or learn in multimedia environments. Several agents’ characteristics may moderate their instructional effectiveness, including appearance, gender, nonverbal communication, motion, and voice. Here, we conducted a meta-analysis to test hypotheses from diverse theories predicting the effects of these agents’ characteristics. We tested predictions of cognitive load theory, cognitive theory of multimedia learning, computers are social actors, social agency theory, uncanny valley, and the action observation network. Our meta-analysis of 32 effect sizes (N?=?2104) revealed a small overall effect (g+?=?0.20), showing that learning with multimedia pedagogical agents was more effective than learning without these agents. As predicted by the redundancy effect of cognitive load theory and the coherence principle of cognitive theory of multimedia learning, 2D agents (g+?=?0.38) tended to be more effective than 3D agents (g+?=?0.11). As predicted by the computers are social actors hypothesis, most of the agents’ characteristics, including nonverbal communication, motion, and voice, appeared not to moderate their effectiveness. We conclude that multimedia pedagogical agents help learning through multimedia, and that students may be able to learn similarly from different types of agents.

Existing research highlights conflicting results attempting to capture gender preferences with respect to unimodal versus multimodal designs in online learning. As online learning continues to expand, more research examining the role of gender in multimedia design holds considerable potential. However, the presence of multimedia in online learning contexts presents a more complex problem when taking into consideration the concept of learner interest. The current study sought to investigate gender differences in situational interest (SI) with respect to three different but related designs of an online, multimedia learning environment for continuing, professional education in emergency medical services. The content in these designs was identical, but applied different combinations of the redundancy and modality multimedia principles. A two-way analysis of variance was used to examine the types of SI by gender and type of multimedia design. While no significant difference or interaction effect was identified between gender and triggered SI, an interaction effect was observed for females and the different multimedia designs. Specifically, females reported a higher maintained SI when animation, narration and text were effectively combined. The findings of this study provide insight into best practices for instructional and media designers developing multimedia learning environments as well as future research implications. 相似文献

Many have argued for the importance of continuing engineering education (CEE), but relatively few recommendations were found in the literature for how to use multimedia technologies to deliver it most effectively. The study reported here addressed this gap by investigating the multimedia category preferences of working engineers. Four categories of multimedia, with two types in each category, were studied: verbal (text and narration), static graphics (drawing and photograph), dynamic non-interactive graphics (animation and video), and dynamic interactive graphics (simulated virtual reality (VR) and photo-real VR). The results showed that working engineers strongly preferred text over narration and somewhat preferred drawing over photograph, animation over video, and simulated VR over photo-real VR. These results suggest that a variety of multimedia types should be used in the instructional design of CEE content. 相似文献

Do classroom exemplars promote the application of principles in teacher education? A comparison of videos,animations, and narratives 总被引：2，自引：1，他引：1

Students learned about teaching principles with a multimedia program that either did not include a classroom exemplar illustrating
how to apply the learned principles to the teaching practice (control group) or included a classroom exemplar in video, animation,
or text format. Across two experiments, video and animation groups reported more favorable attitudes towards learning and
were better able to apply the learned principles than the control group. Text and control groups did not differ in their learning
or attitudes towards learning, suggesting that format is an important factor in determining the effectiveness of classroom
exemplars as pedagogical tools for teacher education. Results encourage the use of visual classroom exemplars to promote the
application of theory into practice. 相似文献

What is the role of motivation in multimedia learning? Cognitive theories of multimedia learning tend to focus on instructional methods aimed at reducing extraneous processing (such as highlighting the essential material) or managing essential processing (such as breaking a lesson into parts), whereas motivational theories tend to focus on instructional methods aimed at fostering generative processing (such as adding appealing graphics or challenging scenarios). Moreno's (2005) cognitive affective theory of learning from media is intended to better incorporate motivation and metacognition into theories of multimedia learning, helping to extend or clarify Mayer's (2009) cognitive theory of multimedia learning and Sweller's (Sweller, Ayres, & Kaluga, 2011) cognitive load theory. The research presented in this special section examines motivating instructional features intended to promote generative processing—such as adding appealing graphics (Magner, Schwonke, Aleven, Popescu, & Renkl, 2013; Plass, Heidig, Hayward, Homer, & Um, 2013) or challenging scenarios (D'Mello, Lehman, Pekrun, & Graesser, 2013). Overall, motivational features can improve student learning by fostering generative processing as long as the learner is not continually overloaded with extraneous processing or overly distracted from essential processing. 相似文献

Animation has an inherent advantage over static graphics when presenting dynamic content because it provides a more accurate and realistic depiction. Simultaneously, animation has an inherent disadvantage because most animated information is perceptually transient. In this quasi-experimental study, cognitive load theory was used to investigate the extent to which animation’s transience could be ameliorated with the incorporation of a pause/play feature or a tracing feature that lets previous information remain visually available on screen instead of disappearing after a brief display. Continuous animation, animation with pause/play and their equivalent static graphics, each designed with either a trace or no trace, were used to instruct 228 post-secondary technical education students on how an electrical circuit works. All formats were accompanied with the same on-screen text. The pattern of results, especially the interactions, indicated that animation with a pause/play format obtained the highest efficiency in the no tracing condition, while the continuous animation format obtained the highest efficiency in the tracing condition. These results suggest that by restructuring the dynamic information, the negative instructional consequences of the transient nature of animation can be counteracted to make it more efficient for learning than static graphics. 相似文献

In light of the increased usage of instructional media for teaching and learning, the design of these media as aids to convey the content for learning can be crucial for effective learning outcomes. In this vein, the literature has given attention to how concurrent on-screen text can be designed using these media to enhance learning performance. The present study sought to examine whether utilizing concurrent on-screen summarized text (CST) could improve students’ learning performance while estimating their perception of performance when learning with educational multimedia content. Although the findings did not show a significant improvement in students’ performance on the retention test among the CST groups, students exhibited a considerable higher level of confidence toward their performance. The findings suggest that students who learned with CST educational media may have overestimated their performance. Further analysis and discussion are included. 相似文献

The cognitive load and learning effects of dual-code and interactivity—two multimedia methods intended to promote meaningful
learning—were examined. In Experiment 1, college students learned about the causal chain of events leading to the process
of lightning formation with a set of words and corresponding pictures (Group WP), pictures (Group P), or words (Group W).
Some students were presented with the organized causal chain of events to study, whereas others were given a self-organization
task. Consistent with a cognitive theory of multimedia learning, Condition WP was the highest in instructional efficiency
for retention and transfer. However, contrary to our predictions, having students organize the multimedia materials was detrimental
to transfer. Two follow-up experiments tested the hypotheses that the negative effects of interactivity were due to students'
lack of time control (Experiment 2) and the form of feedback (Experiment 3). The findings showed that interactivity was effective
when students were asked to evaluate their answers before receiving corrective feedback from the system.

The present study examines how changes in the amount of on-screen text will influence student learning from a multimedia instructional
unit on basic concepts of coordinate geometry. The relative effectiveness of two different versions (short-text and whole-text)
of the instructional unit was examined for students who differed in terms of their ability to remember symbolic units, symbolic
systems and symbolic interpretations. A total of 101 seventh graders were randomly assigned to work with either the whole-text
or the short-text version. Student gains were analyzed using pre-test, post-test and retention test scores. Memory ability
was assessed by the sub-tests of the Structure of Intellect-Learning Abilities Test. Results indicated no significant differences
between groups who worked with short-text and whole-text versions. However retention scores of high and low memory groups
who worked with the whole-text version showed significant differences. The whole-text version was observed to favor students
with high memory for symbolic implications. Results suggest that workability of design principles for multimedia instruction
may depend on the nature of the task and characteristics of the learner. 相似文献

The interactivity principle in multimedia learning states that giving learners control over pace and order of instructions decreases cognitive load and
increases transfer performance. We tested this guideline by comparing a learner-paced instruction with a system-paced instruction.
Time-on-task and interactive behavior were logged, and were also related to interest, prior knowledge, and cognitive involvement.
We successfully replicated the interactivity principle in terms of better transfer. However, this coincided with a large increase
in time-on-task. Also, large individual differences existed in the use of learner control options, which were mostly unrelated
to the other variables. Thus, the benefits of introducing learner control in multimedia learning are at the expense of learning
efficiency, and it remains unclear for whom the interactivity principle works best. 相似文献

Spatial split-attention effects have been noted in the research literature, where, under split-attention conditions, integrating text and diagrams has been shown to be effective. From this literature grew the spatial contiguity principle (or spatial contiguity effect), which states that people learn more when related words and pictures are displayed spatially near one another. Research has shown both effects to influence learning; however, little is known about the conditions in which integrated designs are most effective. This meta-analysis examines the influence of integrated designs across numerous moderator variables in order to improve our understanding of under which conditions integrated designs influence learning. A random effects meta-analysis of 58 independent comparisons (n?=?2426) produced an overall effect size of g?=?0.63 (p?<?0.001). Moderator analyses indicated that integrated designs have benefited learning across many intervention-related and context-related moderator variables. Practical and theoretical implications of the findings are provided. 相似文献
