民办高校多媒体教学研究与探索

当代科学技术迅猛发展,多媒体技术已广泛普及。多媒体教学不再是一种新型的教学手段,目前在民办高校已经普遍使用。多媒体教学将计算机多媒体技术与教学相结合,极大地改革了教学方法。但民办高校在多媒体教学实践过程中存在诸多问题,如课件制作不规范、制作优秀的多媒体课件难度大、过分依赖多媒体而缺少互动性,以及授课速度过快,信息超量等。本文针对这些问题进行了分析,并提出了相应对策。     

试论信息时代下多媒体辅助功能在《艺术概论》教学中的应用

如今多媒体辅助教学逐渐成为《艺术概论》新的教学模式,多媒体课件在课堂中的运用可以有效整合教材的结构与内容,把艺术理论的重点、难点以及主要环节都可以在多媒体课件上一一展示出来,充分发挥了课堂教学的资源价值与示例价值。但多媒体辅助教学并不能替代传统的教学方式,应与传统板书教学相结合。     

浅谈教学中使用多媒体课件的实效性

把作为新型教辅手段的多媒体课件应用到教学当中,在初期,曾收到过意想不到的效果,受到师生、管理者和社会的一致好评.然而,正如诸多"现代技术"不同程度地存在利弊两面性一样,过分迷恋并滥用课件则会给我们的教学带来不必要的麻烦,严重影响教学效果.在教学中使用多媒体课件应讲求实效,一切要从实际出发,从学生的成长出发,从教学的根本目标出发,更好地为教学质量的提高服务.同时应建立科学的教学评价体系.     

试析多媒体技术及其设备在中小学劳技课中的有效运用

多媒体技术及其设备在当今社会业在中小学劳技课教育教学过程中也得到高度重视。合理应用多媒体技术及其设备,合理组配多媒体教学系统,合理选用课堂教学软件,合理设计、编制课件,合理运用课件,激发学生对劳动技术课程的学习兴趣。多媒体技术及其设备只是一种工具和手段,它应该是以优化课程教学为目的的教学辅助和功能延续,应该与传统教学方式方法有机结合,不应该出现形式主义而反受其束缚。     

字体大小和呈现位置对多媒体课件文字理解的影响

本研究通过多媒体教室现场实验和实验室实验,以判断成语的感情色彩为测试任务,探讨字体大小和位置对多媒体课件文字理解的影响。结果表明,字体尺寸大于0．26°视角时,位于多媒体教室不同座位区域的被试都能较好地理解多媒体课件呈现的文字内容,而文字呈现位置对多媒体课件文字理解的影响较小。     

多媒体与高效教学课堂

正随着素质教育的进行,多媒体被引入到了教学课堂,丰富了教学形式,激发了学生的学习兴趣,为实现高效教学创造条件。在小学数学教学中,教师要结合教学内容和学生实际有针对性地设计多媒体课件,提高课堂教学效率。一、利用多媒体生动形象的特点,激发学生的学习兴趣多媒体具有直观生动的特点,利用多媒体进行教学,可以把数学中的抽象知识直观化,转化成色彩鲜艳的图片、有趣的动画,让学生在新颖的学习方式中增加数学学习兴趣,积极

Multimedia in the classroom

This paper focuses on setting up a system for developing and displaying multimedia classroom presentations that is both economical and easy to learn. Four separate aspects of the process are considered: (1) a hardware configuration to serve both the development and display processes, (2) selecting authoring software and learning to use it, (3) presentation development including locating and acquiring multimedia resources appropriate to psychology, and (4) some of the problems that can be expected to arise in both development and use of multimedia presentations. Some discussion of interactive courseware is included.

Prototyping “Intelligent” applications for interactive multimedia systems

The termmultimedia refers to the combined use of different media of communication, and originally belonged primarily to the fields of entertainment and education. Advances in computer, audio, and video technology have now brought multimedia possibilities to the individual. Further, they give the user control over what happens. Suchinteractive multimedia systems offer the user personal access to large amounts of information, including pictures, graphics, video, text, and audio. The potential range of applications is very broad, from simple interactions where the user will merely make occasional choices and then sit back and view sections of program material, to more purposeful interactions where the application can help the user to achieve a goal. This article describes research onknowledge-based interactive multimedia systems. Targeted on the new Compact Disc Interactive format, we have protyped an advisor which will help the user to tackle a typical domestic task. The necessary decision-making process can be enlivened by multimedia interaction, and placed on solid ground by the inclusion of expert advice.

Working memory interference during processing texts and pictures: Implications for the explanation of the modality effect

Auditory text presentation improves learning with pictures and texts. With sequential text–picture presentation, cognitive models of multimedia learning explain this modality effect in terms of greater visuo‐spatial working memory load with visual as compared to auditory texts. Visual texts are assumed to demand the same working memory subsystem as pictures, while auditory texts make use of an additional cognitive resource. We provide two alternative assumptions that relate to more basic processes: First, acoustic‐sensory information causes a retention advantage for auditory over visual texts which occurs no matter if a picture is presented or not. Second, eye movements during reading hamper visuo‐spatial rehearsal. Two experiments applying elementary procedures provide first evidence for these assumptions. Experiment 1 demonstrates that, regarding text recall, the auditory advantage is independent of visuo‐spatial working memory load. Experiment 2 reveals worse matrix recognition performance after reading text requiring eye movements than after listening or reading without eye movements.

Mirror-reflecting a picture of an object: what happens to the shape percept?

Although a two-dimensional picture never fully specifies the actual layout of the depicted three-dimensional scene, one is still able to make a three-dimensional interpretation. When a picture is mirror-reflected, the range of plausible scenes possibly corresponding with the depicted scene has not changed with respect to the original depiction. We were curious to find out whether the inherent picture ambiguities would be solved the same way or differently. Participants performed local attitude settings on three sets of pictures: (1) original pictures, (2) left-right mirrored pictures, and (3) up-down mirrored pictures. Pairwise comparison of the pictorial reliefs of the depicted object, reconstructed from the raw settings, revealed dissimilarities. The differences, however, could be drastically diminished by conducting an affine transformation correction taking into account not only the depths, but also the picture plane coordinates. The inherent ambiguities seemed thus to be solved differently between conditions. By factoring out different solutions to the ambiguities, the pictorial reliefs were found to be equivalent.     

Anticipatory modulation of interference induced by unpleasant pictures

In a series of experiments participants were asked to make speeded judgments regarding the correctness of arithmetic equations (arithmetic verification task) that were presented in front of pictures that are assumed to elicit neutral, positive, or strong negative emotional responses. In some conditions, precues predicted the affective valence of the next picture, whereas in other conditions the precues were uncorrelated with the type of picture. The main question was in which way the opportunity to anticipate a forthcoming negatively valenced stimulus would modulate its impact on cognitive performance. Anticipation generally enhanced the interfering effect of unpleasant pictures. This effect was largely independent of the arousal induced by the pictures. The findings suggest that informative precues led participants to integrate the valence of the pictures into their task representation, which in the case of negative pictures resulted in a somewhat paradoxical intensification of emotional interference.     

When every student has a computer: A new perspective on courseware and its development

In this paper, I describe some of the institutional and curricular implications of 100% student access to personal computing. I then explore the new perspective which these conditions create on the availability of courseware, on the process of courseware development, and on future directions in courseware development.
