This article explores how 145 photographs collected from 20 PowerPoint lectures in undergraduate psychology at 16 UK universities were integrated with lecturers’ speech. Little is currently known about how lecturers refer to the distinct types of photographs included in their presentations. Findings show that only 48 photographs (33%) included in presentation slides were referred to explicitly by exploring their features to make a point related to the lecture content, with only 14 of these used to invite student questioning. Most photographs (97 or 67%) represent a case of ‘unprobed representations’, that is, either ‘embedded’ in the talk as ‘illustrations’ of the speech topic or not referred to at all. A taxonomy of uses that lecturers made of the photographs in their slideshows was created through adapting a Peircean semiotic analysis of the photograph–speech interaction. The implications in terms of lecturer and student engagement with the photographic material are discussed, arguing the case for more Critical Semiotic Exploration of photographs in HE practice. 相似文献

演示软件PowerPoint已成为传授、展示和分享知识的首选方式.这种新型知识传播媒介使用中所隐含的问题是,PowerPoint所支持的认知和教学方式不利于高级分析思考能力的发展和强大叙述理解能力的获得.本文对PowerPoint如何引导教师以特殊方式重新整理知识并如何随之将这些知识在课堂上讲授给学生们进行了研究,这种获取、联系和介绍知识的特殊形式一方面取决于教师对该软件工具默认模式的适应程度,另一方面则取决于这种传播媒介本身的优越性. 相似文献

教师在利用PowerPoint教学课件进行讲课时,经常会用到PowerPoint的圈点功能。但是,PowerPoint的圈点功能存在较大的局限和不足,绘图笔没有提供如直线、方框、圆圈、椭圆等规则的圈点图形,而只提供了涂鸦式画线的功能。为此,本文利用VBA编程实现了PowerPoint教学课件的规则图形圈点,弥补了PowerPoint只能进行涂鸦式画线圈点的不足。PowerPoint教学课件规则图形圈点的实现,将能较大地提高教师多媒体教学的工作效率和学生听课的效果,从而有助于提高教学质量。 相似文献
