Learning style and program design in interactive multimedia

This study was conducted to investigate the effects of variations in the design and delivery of interactive multimedia (IMM) on the learning and attitudes of elementary education majors. A multivariate analysis of variance was conducted with three independent variables—small group or individualized format, inductive or deductive design of instruction, and match of learner style to instruction—and four dependent variables—content scores, observation skill scores, overall satisfaction, and attitude toward learner control of instruction. Scores on the observation skills evaluation were significantly higher when the student's learning style was matched with the design of instruction. Satisfaction and attitude outcomes were significantly different for format: students in the small group were more satisfied, while those using the individual learning station were more strongly agreed that they controlled the pace and sequence of their own instruction. Content scores were not significantly different. In the future, the use of interactive multimedia with various formats and designs may serve to meet the needs of students with differing learning styles and at different developmental levels.     

Empirically-based guidelines for the design of interactive multimedia

While interest in interactive multimedia continues to grow, thus far its activities have been driven more by technological capacity than research and theory. Typically, guidelines for interactive multimedia design are based not upon empirical evidence, but on the intuitive beliefs of designers. In this article, relevant research and theory are organized within an overarching framework, and their principles and implications for the design of interactive multimedia are derived.     

A framework for designing interactive multimedia to scaffold young children's understanding of historical chronology

Young children's understanding of thehistorical past is often characterised by alack of temporal differentiation and a sense oftotal discontinuity with the present. Researchhas suggested that this situation may be causedin part by their formation of inappropriaterepresentations when solving problems ofchronology. To help children construct moreappropriate external representations forparticular tasks and reason more effectivelywith them about chronological concepts, weinvestigated the role that interactivemultimedia might play in scaffoldingteacher-led activities in the classroom. Inthis paper we report on our conceptual designand pedagogical approach to developingeffective dynamic, interactive representationsand activities at the computer interface, aimedat bridging the conceptual gap between concreteexperience and abstract concepts. Evaluationsof the software built using this frameworkshowed that the program was well received bychildren and teachers alike, and that it wasable to facilitate children's understanding of,and ability to reason about, chronology.     

Supporting learning with interactive multimedia through active integration of representations

When learners explore dynamic and interactive visualisations they are often not able to interact with them in a systematic and goal-oriented way. Frequently, even supporting learners in processes of discovery learning does not lead to better learning outcomes. This can be due to missing pre-requisite knowledge such as the coherent mental integration of the pictorial and symbolic sources of information. In order to support learners in this process, we encouraged them to interactively and externally relate different static sources of information to each other before exploring dynamic and interactive visualisations. We evaluated the benefit of this instructional support in two experimental studies concerning the domains of statistics and mechanics. It revealed that the active integration of static representations before processing dynamic visualisations resulted in better performance and can provide a basis for a more systematic and goal-oriented experimentation behaviour during simulation-based discovery learning.in final form: 16 November 2004     

Narrative, linearity and interactivity: making sense of interactive multimedia

A novice to IMM is confronted by a new medium which transforms narrative structures which have evolved over thousands of years. This article focuses on educational interactive media for which the notion of multiple interpretations has different implications, particularly for comprehension and cognition. It reports on experiments with a number of multimedia packages to see how children make sense of interactive media.

对高校运用多媒体课件教学与教学效果的相关因素探究

本研究就高校课堂教学中多媒体课件教学效果的相关因素,对西北民族大学12所学院的500名师生进行了相关调查研究。结果显示：课件制作质量、教师教学方法与教学效果之间存在显著正相关;课堂教学环境中,音响效果与教学效果之间也存在一定正相关;教师普遍认为课件操作水平对教学效果无显著影响：学生则认为教师的课件操作水平对教学效果影响显著。     

人际信任的神经生理机制

人际信任是人际交往中一种常见、重要的心理现象。但研究者对信任的定义还存在不同观点。在研究方法上可以分为两类:一类是根据定义,编制题目来测量信任;另一类是行为游戏法,包括囚徒两难游戏、最后通牒游戏和信任游戏。社会神经认知科学家研究发现,人际信任不存在一个特定的中枢,它跟杏仁核,前中间前额皮质,旁扣带回,脑岛,腹侧被盖区,中隔区,梭状回,颞上回,眶额叶皮层等脑区有关,跟催产素、加压素和多巴胺等化学物质有关。同时,该研究指出了信任研究存在的不足。

Desktop multimedia environments to support collaborative distance learning

Desktop multimedia conferencing, when two or more persons can communicate among themselves via personal computers with the opportunity to see and hear one another as well as communicate via text messages while working with commonly available stored resources, appears to have important applications to the support of collaborative learning. In this paper we explore this potential in three ways: (a) through an analysis of particular learner needs when learning and working collaboratively with others outside of face-to-face situations; (b) through an analysis of different forms of conferencing environments, including desktop multimedia environments, relative to their effectiveness in terms of meeting learner needs for distributed collaboration; and (c) through reporting the results of a formative evaluation of a prototype desktop multimedia conferencing system developed especially for the support of collaborative learning. Via these analyses, suggestions are offered relating to the functionalities of desktop multimedia conferencing systems for the support of collaborative learning, reflecting new developments in both the technologies available for such systems and in our awareness of learner needs when working collaboratively with one other outside of face-to-face situations.
