Effects of study intention and generating multiple choice questions on expository text retention

Teachers often recommend their students to generate test questions and answers as a means of preparing for an exam. There is a paucity of research on the effects of this instructional strategy. Two recent studies showed positive effects of generating test questions relative to restudy, but these studies did not control for time on task. Moreover, the scarce research available has been limited to the effects of generating open-ended questions. Therefore, the aim of this study was to investigate whether generating multiple-choice test questions would foster retention (as measured by a multiple-choice test) relative to restudy when time would be kept constant across conditions. Using a 2 × 2 design, university students (N = 143) studied a text with the intention of either generating test items or performing well on a test, and then either generated multiple-choice items or restudied the text. Retention was measured by means of a multiple-choice test, both immediately after learning and after a one-week delay. Results showed no effects of study intention. Generating multiple-choice items resulted in lower test performance than restudying the text for the same amount of time.     

对桥梁挠度检测技术的研究

故园并不如梦——张炎梦词文化符号心态透视

宋代遗民词人张炎在国破家亡之后,以其苍凉之词追忆繁华的逝去,其词多处言梦,以亡国之哀绪表现文化之苦恋,构成他独特的文化心态。"梦"字作为一种幻灭情绪的文化符号表达了其对故国特有的热爱、留恋。破碎的心灵遂得精神的回归。这种文化深恋传递了特定历史时期遗民士大夫的政治情感,抒发了徘徊在异族统治下的寂寞、无奈、凄凉的心境。其历史人格与执着于文化的传统亦在这梦的倾诉中得以重生。     

草原文学：民族文化的记忆书写

草原文学是草原生活生命动态过程经验性的生动记忆,它以完全经验体验的方式,记忆下了草原文化在生生不息的生命状态中的产生和发展。从物质文化到精神文化,草原文学以符号的形式记忆了鲜活完整的草原生活图景。因此本文认为草原文学是对生活在草原上的、以游牧生活为特征的、蒙古族为代表的文化生活的记忆书写。草原文学用语言符号记录下了民族文化生活的形成史,在其中摹写草原之美景,叙写草原制度与民俗,留住草原民族的日常生活,展现民族精神,书写了民族历史的生命记忆。     

西塞神舟会：民俗文化与现代心理的碰撞与对抗

在与现代经济生活及其文化心理的对抗状态下,西塞神舟会这一传统民俗事象正面临着重大的考验,本土文化记忆有丧失或者被涂改的可能。一方面,它源于记忆群体的缓慢改变。而且,观光者,包括文化官员、学者和游客们,又以新的记忆形态来看待和描述这一民俗事象,引发记忆的偏移。另一方面,商业文化的介入,令民俗活动的关注力分散,造成活动目的的模糊和游移。关护和培植西塞神舟会生存的本地土壤,修复和重建基于本土、本地域的记忆共同体已经成为重要的课题。     

建设“中国记忆”数字资源库的构想

当前中华民族面临"集体失忆"的危险,传承中国记忆具有极其重要的意义。建议国家档案局牵头建设一个基于互联网的,以档案为主、用各种形式记录和反映华人灿烂悠久的历史文化和绚丽多彩的社会生活的,供全民免费便捷利用的国家级、综合性的数字资源库——"中国记忆"。提出了"中国记忆"数字资源库工程的内涵和使命、价值理念、建设原则、基本内容和资源架构等。

The relationship between working memory and writing in younger and older adults

This study investigated therelationship between working-memory (WM) spanand writing performance in three age groups(mean of ages of 15, 30, 77 years). Asexpected, older adults' performance wasinferior to younger adults on measures ofverbal and visual-spatial WM and structuralcomplexity in writing. More important, WM spanmoderated structural complexity in writingacross age and those effects remainedsignificant when short-term memory, readingcomprehension, word knowledge, spelling andhandwriting speed were partialed from theanalysis. Overall, the results support thenotion that age-related changes in textgeneration are moderated by limitations in ageneral WM system.     

Examining the evidence from TIMSS: Gender differences in Year 8 science achievement in Australia

Australia's continuing participation in international science studies such as TIMSS provides a useful lens through which to monitor achievement in science over time. Gender differences in science were not evident in the early years of TIMSS but appear to be growing. This article examines gender differences in science achievement in early secondary schooling in Australia using data from the TIMSS 2003 study. The aim is to explore the cultural, social, structural and institutional factors that may differentially influence science achievement, with the aim of identifying which are more important for males and for females.
