让儿童的耳朵飞扬——故事教学中视听媒介对儿童倾听的影响

随着现代化视听媒介的逐渐介入,视听媒介在语言教学中出现了不适宜、不适合的干扰,强烈的视听刺激冲击了听觉刺激,多彩的教具冲淡了儿童对文学作品感受、理解和表达的过程。为此,笔者在故事教学中通过专注性倾听依赖“视听”整合,理解性倾听依靠“视听”比例,辨析性倾听依托“视听”技巧等策略,试图将现代化视听媒介扬长避短,在儿童早期的故事教学中避免由于视听媒介重复使用、不当使用对儿童倾听所造成的无法挽回的影响。

Does adding video and subtitles to an audio lesson facilitate its comprehension?

We examined whether adding video and subtitles to an audio lesson facilitates its comprehension and whether the comprehension depends on participants' cognitive abilities, including working memory and executive functions, and where they looked during video viewing. Participants received lessons consisting of statements of facts under four conditions: audio-only, audio with verbatim subtitles, audio with relevant video, and audio with both subtitles and video. Comprehension was assessed as the accuracy in answering multiple-choice questions for content memory. We found that subtitles facilitated comprehension whereas video did not. In addition, comprehension of audio lessons with video depended on participants' cognitive abilities and eye movement pattern: a more centralized (looking mainly at the screen center) eye movement pattern predicted better comprehension as opposed to a distributed pattern (with distributed regions of interest). Thus, whether video facilitates comprehension of audio lessons depends on both learners’ cognitive abilities and where they look during video viewing.     

构建基于Internet的高校教学视音频资源库

The Effect of Selected Media Feedback upon the Interactive Behavior of Student Teachers

Abstract

The problem involved in this study was to ascertain whether student teachers receiving supervisory feedback with the aid of video and/or audio tape replay demonstrate a greater change in their classroom verbal interactive behavior than student teachers who receive supervisory feedback with no video or audio feedback. Evidence indicates that those receiving video feedback utilize less “direct teaching influence” and more “indirect teaching influence” as categorized by Flanders’ Verbal Interaction Analysis System, Within the audio group, the magnitude of change in the student teachers’ instructional behavior was not statistically significant. The magnitude of the directional change was greater for those students receiving video or audio recorded feedback than the magnitude of change in the control group.     

Empirical comparison of alternative instructional TV technologies

An experiment was conducted to compare training effectiveness and user acceptance of live instruction andsix different alternative Instructional TV (ITV) technologies: multi‐channel 2‐way video with 2‐way audio, single‐channel 2‐way video with 2‐way audio, 1‐way video with 2‐way audio, 1‐way video with 1‐way audio, 1‐way video with intermittent 2‐way audio, and audiographics. Findings were that, in comparison with live instruction, ITV in several different forms was effective both in terms of student performance and acceptance. The most successful ITV technologies were those allowing continuous 2‐way audio communication between classrooms with either 2‐way or 1‐way video. Student test performance was poorer with ITV systems that restricted remote students' ability to converse with or see the instructor and the performance decrement was evident in both local and remote classrooms.

The research described was performed under the sponsorship of the Office of Naval Technology. The opinions expressed in this paper are those of the authors, are not official, and do not necessarily reflect the views of the Navy department.
