How generative drawing affects the learning process: An eye‐tracking analysis

Generative drawing is a learning strategy in which students draw illustrations while reading a text to depict the content of the lesson. In two experiments, students were asked to generate drawings as they read a scientific text or read the same text on influenza with author‐provided illustrations (Experiment 1) or to generate drawings or write verbal summaries as they read (Experiment 2). An examination of students' eye movements during learning showed that students who engaged in generative drawing displayed more rereadings of words, higher proportion of fixations on the important words, higher rate of transitions between words and workspace, and higher proportion of transitions between important words and workspace than students given a text lesson with author‐generated illustrations (Experiment 1) or students who were asked to write a summary (Experiment 2). These findings contribute new evidence to guide theories for explaining how generative drawing affects learning processes.     

Is the seductive details effect moderated by mood? An eye‐tracking study

According to the seductive details (SD) effect, interesting, but irrelevant information in learning materials reduces learning outcomes. Basic research suggests that subjects in positive mood are more distractible by task‐irrelevant stimuli than subjects in negative mood. Hence, mood could moderate the SD effect. We tested this assumption by comparing eye movements to seductive pictures in participants in positive versus negative mood. As expected, participants in positive mood fixated pictures longer and more frequently than participants in negative mood, which can be interpreted in terms of mood‐based higher distractibility. However, this did not translate to a more pronounced SD effect in the learning test. Unexpectedly, there was no SD effect in either mood condition. We discuss implications of the eye‐tracking data as well as potential reasons for the nonexistent SD effect in our study.     

一图抵千言：多媒体学习中的自我生成绘图策略

自我生成绘图是指学生使用可视化的学习方法绘制一幅能反映每一段文字中重要观点的图画, 通过图文结合的方式来促进学习的一种策略。综述以往研究发现, 先前研究通过操纵文本、动画等学习材料来考察自我生成绘图在学习中的作用, 发现自我生成绘图的效果并不稳健：一方面它可以通过提高学生的认知和元认知能力、激发积极的情感状态而提高学习效果, 得到了绘图建构生成理论和多媒体学习认知理论的支持; 另一方面也可以通过增加认知负荷而阻碍学习, 得到了认知负荷理论的支持。整体而言, 自我生成绘图策略还是有利于学习的, 已有研究在学习效果上的效应量中值为d_保持 = 0.13, d_理解 = 0.46, d_迁移 = 0.38。未来的研究仍需要关注自我生成绘图策略的材料操纵、效果评定以及潜在变量等等。     

视觉、听觉情绪设计对多媒体学习的影响

以大学生为被试,特异性免疫工作原理为材料,通过实验法研究视觉、听觉情绪设计对多媒体学习的影响。实验1发现视觉情绪设计诱发了学习者的积极情绪,提高了保持成绩。实验2发现听觉情绪设计可以诱发学习者的积极情绪,提高相关认知负荷、保持和迁移成绩。研究表明视觉、听觉情绪设计都能显著提高多媒体学习效果。听觉情绪设计的发现突破了已有研究仅从视觉角度优化学习材料的方式,拓展了多媒体学习情绪设计的内涵。     

Differences between multimedia and text-based assessments of emotion management: An exploration with the multimedia emotion management assessment (MEMA)

People process emotional information using visual, vocal, and verbal cues. However, emotion management is typically assessed with text based rather than multimedia stimuli. This study (N?=?427) presents the new multimedia emotion management assessment (MEMA) and compares it to the text-based assessment of emotion management used in the MSCEIT. The text-based and multimedia assessment showed similar levels of cognitive saturation and similar prediction of relevant criteria. Results demonstrate that the MEMA scores have equivalent evidence of validity to the text-based MSCEIT test scores, demonstrating that multimedia assessment of emotion management is viable. Furthermore, our results inform the debate as to whether cognitive saturation in emotional intelligence (EI) measures represents “noise” or “substance”. We find that cognitive ability associations with EI represent substantive variance rather than construct-irrelevant shared variance due to reading comprehension ability required for text-based items.

多媒体互动插图对科学说明文学习的影响

48名 1 3岁中学生被分为高低两种学习能力 ,每种被试又被分成两组分别学习配有两种插图 (多媒体静态插图和多媒体互动插图 )的一篇生物说明文 ,结果表明 :( 1 )在重在考查插图加工水平的图片测验上 ,学习能力和插图类型主效应均显著 ,但两者之间不存在显著交互作用 ;( 2 )在重在考查文图整合加工水平的文字测验上 ,学习能力和插图类型之间存在显著的交互作用 ,即只有当学习能力高时 ,两种插图之间存在显著差异。 ( 3 )在被试的填图过程中 ,被试的尝试次数与其插图加工时间及学习效果之间存在显著的相关。这说明 ,多媒体互动插图可促进所有被试对插图的加工 ,但只能促进学习能力高者对图文的整合加工 ,而且多媒体互动插图对学习的促进效果与被试加工插图时的实际加工深度有关     

Thirty years of research on online learning

This paper presents a personal account of developments in research on online learning over the past 30 years. Research on how to design online instruction represents an example of applying the science of learning to education. It contributes to the science of learning (as exemplified by developments in cognitive load theory, the cognitive theory of multimedia learning, and incorporating metacognitive, motivational, and affective aspects of learning), the science of instruction (as exemplified by the continuing development of research‐based principles of instructional design), and the science of assessment (as exemplified by supplementing self‐report surveys and retention tests with multilevel transfer tests, log file data during learning, and cognitive neuroscience measures of cognitive processing during learning). Some recurring themes are that learning is caused by instructional methods rather than instructional media, so research should focus on features that are uniquely afforded by digital learning environments; instructional practice should be grounded in rigorous and systematic research, including value‐added experiments aimed at pinpointing the active ingredients in online instruction; research in online learning should identify boundary conditions under which instructional techniques are most effective; and research in online learning should test and contribute to learning theory.     

英语多媒体学习中言语关联手势对认知负荷的影响

为了探讨英语多媒体学习中言语关联手势对认知负荷及学习成绩的影响,采用2×2被试间实验设计。结果发现：该手势对认知负荷影响的主效应不显著,但与英语语言技能水平之间存在交互作用,当学生语言技能水平低时,手势增加了认知负荷,反之,则降低认知负荷;该手势对句子转换的成绩没有明显影响,但在学生语言技能高时能提升理解能力的成绩。本研究结果提示,言语关联手势的运用有明显作用,它能提高或降低认知负荷,并对理解能力的成绩产生影响,但其大小和方向依赖于学生英语语言技能水平。     

动画教学代理对多媒体学习的影响:学习者经验与偏好的调节作用

以往研究发现,动画教学代理对多媒体学习效果的影响不一致,可能受到学习者特征和偏好的调节。本研究以“空调的组成部分及工作原理”为实验材料,采用两个实验控制教学代理有无、经验高低和代理偏好,探讨动画教学代理对多媒体学习的影响。实验1发现与无代理组相比,代理组对教学视频的注视点个数更多,平均眼跳潜伏期更短,学习兴趣也更高;低经验者在代理条件下的迁移成绩更好。实验2发现学习者在偏好代理和非偏好代理条件下的迁移成绩好于无代理组;偏好代理组感知到更低的认知负荷,对总体视频的注视点个数和注视频率更多,平均眼跳潜伏期更短,对学习内容的注视点个数更多。结论认为：在多媒体中加入教学代理不会减少学习者对学习内容的注意,能提高多媒体学习效果,支持社会代理理论假设;教学代理能提高低经验者的学习效果,但对高知识经验者无明显作用;加入学习者偏好的代理形象会促进学习,但加入学习者非偏好的代理形象并没有阻碍学习。
