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

Emotional design of multimedia instruction involves making the essential elements in the lesson's graphics more appealing, such as by rendering them with human-like features and with distinct, appealing colors (Um, Plass, Hayward, & Homer, 2012). College students received an 8-slide multimedia lesson on how a virus causes a cold for 5 min (Experiment 1) or for as long as they wanted (Experiment 2). For the control group, the graphics consisted of simple black-and-white drawings in which the host cell was represented as a large circle, and the virus was represented as a small circle with small spikes on the outside and a rectangle on the inside. For the enhanced group, the graphics were redrawn to render the host cell as a red face with expressive eyes (registering surprise, fear, and sickness at various stages in the process), and the virus as a blue face with fierce eyes and with a green dot at the end of each of the blue tentacles surrounding the virus face. The enhanced group performed better than the control group on a subsequent learning test (d = 0.69 in Experiment 1, d = 0.65 in Experiment 2) and gave higher effort ratings in Experiment 1 (d = 0.65) but not in Experiment 2 (d = −0.10). The findings are generally consistent with the cognitive affective theory of learning with media, and point to the importance of incorporating motivation into cognitive theories of multimedia learning. 相似文献

多媒体学习理论是一个贯通了学习理论与教学理论的科学体系。作为学习理论的多媒体学习认知理论基于双重编码理论、工作记忆模型以及生成加工理论,解释了学习者通过加工语词与画面所呈现的材料来建构知识的学习机制,属于解释性理论;作为教学理论的多媒体教学设计理论发展出一系列教学设计应遵循的原则,为教育实践提供了具有处方性意义的行动指南,属于处方性理论。解释性的学习理论为处方性的教学理论提供了扎实可靠的科学基础。在多媒体学习研究从学习理论向教学理论转化的过程中,多媒体教学设计理论是实现跃迁的关键环节,而认知负荷理论则是理论跃迁成功的关键变量。基于认知负荷理论,梅耶提出多媒体学习认知负荷三元模型,包括必要认知加工、外来认知加工和生成性认知加工。围绕这三类认知加工,梅耶及其同事进行了大量的实验研究,最终确定了12项与多媒体学习认知理论及其前提假设保持高度逻辑一贯性的多媒体教学设计原则。这些原则都是经得起实践检验的,但教学设计人员在应用的过程中,应明确各项原则的问题情境、适用范围等边际条件。 相似文献

梅耶的多媒体学习理论是建立在坚实的理论基础和可靠的实证经验基础上的科学体系。多媒体学习的认知理论是理解多媒体学习的关键。双重通道假设、容量有限假设和主动加工假设是梅耶构建多媒体学习认知理论的基石,也是整个多媒体学习科学体系的逻辑起点。这三大假设赖以成立的理论前提正是双重编码理论、工作记忆模型、生成学习理论和认知负荷理论,由此构成了多媒体学习的理论基础。具体而言,双重编码理论和工作记忆模型为多媒体学习的认知理论构建提供了关键概念与元素;生成学习理论则为多媒体学习的认知理论构建提供了基本的解释性框架;多媒体学习的认知理论正是由这些关键概念、元素和解释性框架整合而成;而认知负荷理论则以多媒体学习的认知理论为基础,进而为多媒体教学的系列设计原理提供了关键支撑。 相似文献

Learning with hands-on experiments can be supported by providing essential information virtually during lab work. Augmented reality (AR) appears especially suitable for presenting information during experimentation, as it can be used to integrate both physical and virtual lab work. Virtual information can be displayed in close spatial proximity to the correspondent components in the experimentation environment, thereby ensuring a basic design principle for multimedia instruction: the spatial contiguity principle. The latter is assumed to reduce learners' extraneous cognitive load and foster generative processing, which supports conceptual knowledge acquisition. For the present study, a tablet-based AR application has been developed to support learning from hands-on experiments in physics education. Real-time measurement data were displayed directly above the components of electric circuits, which were constructed by the learners during lab work. In a two group pretest–posttest design, we compared university students' (N = 50) perceived cognitive load and conceptual knowledge gain for both the AR-supported and a matching non-AR learning environment. Whereas participants in both conditions gave comparable ratings for cognitive load, learning gains in conceptual knowledge were only detectable for the AR-supported lab work. 相似文献

Well-designed instructional videos are powerful tools for helping students learn and prompting students to use generative strategies while learning from videos further bolsters their effectiveness. However, little is known about how individual differences in motivational factors, such as achievement goals, relate to how students learn within multimedia environments that include instructional videos and generative strategies. Therefore, in this study, we explored how achievement goals predicted undergraduate students’ behaviors when learning with instructional videos that required students to answer practice questions between videos, as well as how those activities predicted subsequent unit exam performance one week later. Additionally, we tested the best measurement models for modeling achievement goals between traditional confirmatory factor analysis and bifactor confirmatory factor analysis. The bifactor model fit our data best and was used for all subsequent analyses. Results indicated that stronger mastery goal endorsement predicted performance on the practice questions in the multimedia learning environment, which in turn positively predicted unit exam performance. In addition, students’ time spent watching videos positively predicted practice question performance. Taken together, this research emphasizes the availing role of adaptive motivations, like mastery goals, in learning from instructional videos that prompt the use of generative learning strategies. 相似文献

ABSTRACT An adaptation of Bagley's (1990) experiment which compared the interaction of instructional format with adult learners was carried out replacing the Wechsler Adult Intelligence Scale (WAIS) arithmetic reasoning subtest with the Riding & Cheema (1991) Cognitive Styles Analysis (CSA). There was an additional inclusion of graphics to the structured instructional format, as an independent variable. A total of 45 participants attended workshops to learn how to write PASCAL programs. All of the participants completed the CSA and their CSA‐ratio was used to select pairs of similar CSA‐ratios. One participant from each pair was given a text‐only instructional booklet, while the other was given a text‐plus‐graphics instructional booklet. The treatment groups were controlled for instructional format (text‐only/text‐plus‐graphics) and cognitive style. The independent variables were used to test for their effect on learning abstract computer programming concepts. It was found that the Verbal‐Imagery cognitive style and instructional treatment interacted in their effect on the performance‐difference scores. The Novice‐Verbal programmers performed best with a text‐plus‐graphics instructional format, performing significantly better than the Novice‐Imagers’ subgroups using the same text‐plus‐graphics material. Conversely, the Novice‐Imagers participants performed better with the material. However, the Experienced‐Imagery participants performed better with the text‐plus‐graphics instructional material than the Experienced‐Verbalisers. Overall, the Verbalisers’ worst performance occurred with the text‐only materials, while their best performance occurred with the text‐plus‐graphics material. This pilot experiment suggests that learning performance is affected by an interaction of cognitive style and instructional format. However, this interaction was contrary to expectations (Riding & Douglas, 1993), with Verbalisers performing best with text‐plus‐graphics instructional material and Novice‐Imagers performing best with text‐only instructional material. 相似文献

A decisive factor in the determination of effective Gifted Education is the fit between the individual cognitive and motivational pre‐conditions of the learning process and the instructional situation. This central thesis is based partly on the multidimensional talent and giftedness concepts and partly on the interaction between the individual learning needs and learning opportunities as found in the Aptitude‐Treatment‐Interaction Model (Corno & Snow, 1986). In a series of quasi‐experiments in a school setting, so‐called attributional retraining has proved to be an effective intervention method in reducing helplessness and similar unfavorable behavior patterns. This procedure works according to Weiner's causal attribution model (Weiner, 1986) and Dweck's model of achievement motivation (Dweck & Leggett, 1988). The possibilities of using this method in school settings are shown in this article and the method's contribution to the promotion of the gifted is discussed.

Animation as an Aid to Multimedia Learning 总被引：12，自引：0，他引：12
How can animation be used to promote learner understanding of scientific and mathematical explanations? In this review, we examine the role of animation in multimedia learning (including multimedia instructional messages and microworld games), present a cognitive theory of multimedia learning, and summarize our program of research, which has yielded seven principles for the use of animation in multimedia instruction. These include the multimedia principle (present animation and narration rather than narration alone), spatial contiguity principle (present on-screen text near rather than far from corresponding animation), temporal contiguity principle (present corresponding animation and narration simultaneously rather than successively), coherence principle (exclude extraneous words, sounds, and video), modality principle (present animation and narration rather than animation and on-screen text), redundancy principle (present animation and narration rather than animation, narration, and on-screen text), and personalization principle (present words in conversational rather than formal style). Animation can promote learner understanding when used in ways that are consistent with the cognitive theory of multimedia learning. 相似文献

In this commentary, we utilize a social cognitive view of self-regulation to analyze the computer-based learning environments (CBLEs) that are described in the various articles in this volume. Although these CBLEs are creative ways of engaging students' metacognitive processes, their impact on students' motivational beliefs and self-reactions has been given relatively little attention to date. Self-regulation research on these sources of motivation in traditional learning environments has shown that they can play a vital role in explaining students' self-initiative and perseverance in the face of setbacks. When analyzing the forms of self-regulatory instruction that were employed, 2 of the CBLEs followed the first 2 sequential levels of a graduated "social-to-self" pattern advocated by social cognitive researchers. However, the other CBLEs often made nonsequential use of such social cognitive instructional processes as modeling, tutoring, providing feedback, and self-research. 相似文献

The effective design of course materials is critical for student learning, especially for large lecture introductory courses. This quantitative study was designed to explore the effect multimedia and content difficulty has on students’ cognitive load and learning outcomes. College students (n = 268) were randomized into 1 of 3 multimedia groups: text + graphics (Group 1–TG); audio + text + graphics (Group 2–ATG); or video + audio + text + graphics (Group 3–VATG). Participants answered a demographic survey and pretests before viewing 2 food science supplemental lecture materials (i.e., water mobility and amino acid structures) and completing the cognitive load instrument and post‐tests within a noncontrolled setting. Cognitive load scores were tabulated and compared using a 3 × 3 ANOVA and Tukey post hoc analysis across multimedia groups and food science supplemental lecture materials. Based on the post hoc, students in Group 1–TG had higher intrinsic cognitive load scores than Group 2–ATG (ANOVA, P < 0.05). Cognitive load and post‐test scores were tabulated and compared using a spearman correlation across groups. In Group 1–TG, students that reported less intrinsic cognitive load had higher post‐test scores. Also, students that reported more germane cognitive load had higher post‐test scores. In Groups 2–ATG and 3–VATG, students that reported less extraneous cognitive load had higher post‐test scores (ANOVA, P < 0.05). 相似文献

This article discusses an intervention project by means of motivational approaches in a British culture survey course for English majors in mainland China's university classroom context. The intervention uses such motivational theories as attribution and task orientation to motivate the teaching and learning of the EFL course so as to create a cooperative classroom environment. Theoretical bases of the Chinese heritage culture and motivation are examined, specific intervention procedures discussed, relevant data analysed and finally some suggestions regarding the EFL teachers' important role in promoting the quality of EFL education are made. The intervention results show that an innovative pedagogy to motivate students' metacognitive awareness, cognitive and socio‐cognitive ability in cooperative classroom learning situations different from the traditional cramming methods and examinations proves effective. Motivation should be given a central role in promoting China's EFL quality education. 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

A motivational perspective on the relation between mental effort and performance: Optimizing learner involvement in instruction 总被引：3，自引：0，他引：3
Fred Paas Juhani E. Tuovinen Jeroen J. G. van Merriënboer A. Aubteen Darabi 《Educational technology research and development : ETR & D》2005,53(3):25-34
Motivation can be identified as a dimension that determines learning success and causes the high dropout rate among online learners, especially in complex e-learning environments. It is argued that these learning environments represensent a new challenge to cognitive load researchers to investigate the motivational effects of instructional conditions and help instructional designers to predict which instructional configurations will maximize learning and transfer. Consistent with the efficiency perspective introduced by Paas and Van Merriënboer (1993), an alternative motivational perspective of the relation between mental effort and performance is presented. We propose a procedure to compute and visualize the differential effects of instructional conditions on learner motivation, and illustrate this procedure on the basis of an existing data set. Theoretical and practical implications of the motivational perspective are discussed. 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

Continuing intrinsic motivation to learn is the result of actively generating and implementing a variety of metacognitive, cognitive, and affective processes and skills. An understanding of these processes, skills, and their interrelationships forms a basis for the design of an effective motivational skills training program. This article advances a generative process model of continuing motivation in which the central role of perceived self‐efficacy and personal control are explicated. Support for this model from current theories of learning and motivation is presented, along with implications for specific skills training interventions. It is argued that the functional purpose of motivational skills training is to promote perceptions of self‐efficacy and personal control that underlie the ability to take positive self‐control and change negative attitudes and orientations toward learning. For students with motivational deficiencies, this training is a necessary precursor to their active engagement in the learning process and execution of appropriate learning strategies and skills. 相似文献

Previous research has shown that cognitive processing and achievement strategies are important for motor learning and achievement. Despite this, there are few studies identifying the role of motivational beliefs in the cognitive self-regulation of students' learning in physical education classes. This study reports the results of multivariate analyses of the relationships between thirteen to fourteen-year-old secondary school pupils' (n=343) implicit theories of ability and their self-regulated learning in PE. Self-regulation measures included metacognitive/elaboration strategies, effort regulation and adaptive help seeking. Results revealed consistent relationships between motivational beliefs and pupils' use of self-regulation strategies. The results underscore the educational value of reappraising pupils' implicit theories of ability, making them believe in the modifiability of ability through effort and hard work and learning. The results illustrate the importance of linking pupils' motivational and cognitive characteristics to provide a fuller understanding of their self-regulation of learning in physical education. 相似文献

Instructional animation versus static pictures: A meta-analysis 总被引：8，自引：0，他引：8
A meta-analysis of 26 primary studies, yielding 76 pair-wise comparisons of dynamic and static visualizations, reveals a medium-sized overall advantage of instructional animations over static pictures. The mean weighted effect size on learning outcome is d = 0.37 (95% CI 0.25–0.49). Moderator analyses indicate even more substantial effect sizes when the animation is representational rather than decorational (d = 0.40, 95% CI 0.26–0.53), when the animation is highly realistic, e.g., video-based (d = 0.76, 95% CI 0.39–1.13), and/or when procedural-motor knowledge is to be acquired (d = 1.06, 95% CI 0.72–1.40). The results are in line with contemporary theories of cognitive load and multimedia learning, and they have practical implications for instructional design. 相似文献

Cognitive Stimulation is a system of intrinsic motivation which draws upon neo-behavioral, cognitive, and information-processing theories and upon a body of related research. The essential features of this system are the following: (a) a discrepancy between stimulus input and the learner's expectations for that input, (b) instrumental responses by the learner to reduce the discrepancy, and (c) feedback which may have the effect of maintaining the discrepancy or of reducing it by signalling changes in the environment or by modifying the learner's expectations. Based on this formulation, some important instructional considerations include the collative content of the input and the type of expectation which the input violates. In order to maximize their motivational effects, discrepancies must be maintained at optimal levels by manipulating variables such as the total value of the discrepant elements and the degree to which the elements are incompatible. Finally, the motivational impact of discrepancies is subject to the facilitating or debilitating effects of cognitive and personality differences among individual learners. The implications of this system for instructional decision-making were considered in terms of the selection of instructional topics, instructional materials, and instructional strategies. 相似文献
