Prediction of self-reported knowledge with over-claiming, fluid and crystallized intelligence and typical intellectual engagement

We investigated the usefulness of the Over-Claiming Questionnaire (OCQ) as a measure of cognitive abilities. In OCQs respondents are asked to rate their familiarity with items of academic or everyday knowledge (Paulhus, Harms, Bruce, & Lysy, 2003). Some items exist in reality (reals), and others do not (foils). We developed four OCQs, each consisting of 40 reals and 8 foils from the domains of Science, Humanities and Civics. The OCQs were administered in a longitudinal rotation design to 112 participants who attended the 9th school grade at the beginning of the study. In latent variable regression analyses 53% of variation in the reals could be explained by fluid and crystallized intelligence and over-claiming as indicated by responses to foils. Further variation in responses to reals and foils was explained by intellectual engagement. Our results show that self-reported knowledge, although positively related to measures of ability, to a large extent reflects over-claiming.     

A teacher-report measure of children's task-avoidant behavior: A validation study of the Behavioral Strategy Rating Scale

This study aims to validate a teacher-report measure of children's task-avoidant behavior, namely the Behavioral Strategy Rating Scale (BSRS), in a sample of 352 Finnish children. In each of the four waves from Kindergarten to Grade 2, teachers rated children's task-avoidant behavior using the BSRS, children completed reading and mathematics tests, and trained testers rated children's task-avoidant and social-dependent behavior after the test situation. Mothers also rated children's task-avoidant behavior in the last two waves. The results showed that a two-factor model including one factor representing task avoidance and one method factor accounting for wording effects among the negatively phrased items fitted the data best. The scale demonstrated strict measurement invariance across all four waves and satisfactory convergent and discriminant validity. Teacher-reported task avoidance was negatively associated with performance in reading and mathematics. The results suggest that the BSRS is a reliable, valid, and developmentally suitable instrument.     

Gender, BMI, values, and learning in physical education: A study on Chinese middle schoolers

Students' different perceptions of task values influence their learning experience and achievement in physical education. Framed using the subjective task value construct, this study was conducted to determine the extent to which male and female Chinese middle schoolers with different body sizes differed in their perception of the task values. A second goal of the study was to identify the extent to which the task values along with gender and body size predicted students' performance on knowledge and physical skill tests. Data from a random sample of students (N = 860) from eight Chinese middle schools revealed that the boys appreciated intrinsic (p = .001) and utility values (p = 02); both boys and girls, however, equally appreciated the attainment value (p = .73). The boys performed better in physical skill tests than the girls (p = .001), whereas the girls scored higher in knowledge tests than the boys (p = .04). Regression analyses revealed that gender is the only predictor for performance on both knowledge and skill tests. Utility value and body size were predictors for skill, not for knowledge. These findings indicate that Chinese middle school boys and girls differed in valuing and achieving in physical education. The findings imply that Chinese boys need to strengthen cognitive learning and girls need to strengthen psychomotor skill development in physical education.     

科技英语视域下的“UP/DOWN”图式映射

根据莱考夫和约翰逊的概念隐喻和意象图式理论,针对作为意象图式概念的＂Timeo Wew Romvn＂型前置词在科技英语中的图式映射进行新探。研究表明＂Timeo Wew Romvn＂都能够把空间域的意象图式结构从始源域映射到非空间抽象目标域之上,再次佐证＂许多抽象概念结构部分源起于意象图式结构,抽象思维在一定程度上是隐喻思维＂的认知观。

关于中国国际友好城市问题的探讨——以中澳友好省州/城市为例

截至2009年底,我国与五大洲125个国家建立了1683对友好城市关系。自1979年广东省与澳大利亚新南威尔士州建立第一个友好省州关系以来,中国与澳大利亚友好省州/城市关系在数量和质量上都取得了突破性进展。友好城市关系在我国对外交流和发展中发挥了重要作用:消除不同国家之间在文化上的隔阂,促进双方理解和交流;推动国家和地方政府间的经济与贸易合作;成为国家和政府间外交的有益补充。虽然目前中国国际友好城市关系在促进中外文化交流和对外经济发展方面取得了一定成绩,但也存在许多问题。以中澳友好城市关系为例:首先,财政问题是影响友好城市关系发展的重要因素;其次,友好城市关系缺乏严格统一的管理机构;第三,政府在友好城市关系中尚未发挥其应有的作用。为进一步拓展对外结好工作,更好地发挥友好城市在对外交流和地方经济发展中的作用,特提出如下建议:首先,应慎重选择友好城市的结好对象;其次,要从民间和政府两个层面扩大友好城市之间的交流;第三,要以友好城市关系为重要桥梁和渠道,进一步加强经贸领域的合作。     

在《C程序设计》教学中引入ACM/ICPC的学习模式

《C程序设计》已经成为很多高等院校中计算机专业的一门必修课程,它将成为学生走上工作岗位后一种非常有用的工具,也会成为学生学习其它计算机语言的基础。本文通过引入ACM/ICPC的竞赛方式,培养学生的主动式学习、竞争式学习和协作式学习模式,同时培养学生的创造性思维模式。     

OSI参考模型的教学方法

《计算机网络基础》课程是一门发展着的前沿学科,是我院本、专科各专业必修的一门专业基础课程,是通信技术与计算机技术相结合的产物,内容广泛,学习难度较大,尤其在学习计算机网络体系结构这部分知识时,学生的学和教师的教都认为是一重点,也是一难点。所以,本文将从一实例出发逐渐推导出计算机网络体系结构模型OSI/RM的教学内容,从而使学生进一步了解什么是计算机网络体系结构。
