Lecture capture with real‐time rearrangement of visual elements: impact on student performance

The primary goal of this study is to create and test a lecture‐capture system that can rearrange visual elements while recording is still taking place, in such a way that student performance can be positively influenced. The system we have devised is capable of integrating and rearranging multimedia sources, including learning content, the instructor and students' images, into lecture videos that are embedded in a website for students to review after school. The present study employed a two‐group experimental design, with 153 participants (145 females and 8 males) making up an experimental group in which lecture courses were recorded using the new lecture‐capture system, and 149 participants (140 females and 9 males) forming a control group whose lectures were recorded by traditional means. All participants were in the freshman college and studying Introduction to Computer and Information Science in one of six classes, and were randomly assigned to one of the two groups. The participants' midterm examination and final examination scores were collected as indicators of their academic performance, with their mathematics entrance scores used as a pre‐test. The findings obtained from analysis of covariance (ANCOVA) suggest that appropriate rearrangement of visual elements in lecture videos can significantly impact students' learning performance.

国内大剧院混响时间及相关参量特性分析

近20年来国内建成了大量的剧院,对于这些剧院整体上的混响时间特性规律,目前国内仍缺乏类似相关的研究.文章统计了国内50个1 200座以上的典型大剧院,根据实测数据分析了国内剧院混响时间的大小分布及混响时间与早期衰变时间、清晰度与明晰度、观众厅体积等参数的相关性规律;研究发现国内大剧院混响时间较世界上同等规模的国外歌剧院...     

天桥剧场观众厅池座椅背送风方案研究

由于下送风方案可以减小能耗,降低噪音,天桥剧场观众厅池座拟采用下送风方案。本文对天桥剧场观众厅池座部分采用椅背送风时的效果进行了模拟计算,计算工况包括不同的送风温度和不同的诱导比。数值计算结果表明,采用椅背送风,观众身体周围的风发布合理,头部,躯干和大腿处的温度合理,下会对观众造成吹风感或闷热的感觉,当诱导比增大时,送风气流作用的范围增大,人体周围的温度场更加均匀,当送风温差减少时,人体周围的温度     

Psychological perspectives on acting.

Psychologists know surprisingly little about the cognitive and affective underpinnings of acting, and this stands in sharp in contrast to what has been learned about the psychological skills involved in music and the visual arts. In this article, the author discusses findings on the childhood precursors of acting talent and outlines a program of research she is initiating to test the hypothesis that acting training fosters strength in reading others' mental states, feeling others' feelings, and regulating one's own emotions in an adaptive manner. This research has implications for understanding the malleability of these outcomes and expertise in these abilities. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
