Expectancy value interactions and academic achievement: Differential relationships with achievement measures

Motivation predicts academic achievement beyond cognitive ability. Expectancy value theory (Eccles et al., 1983) is a widely accepted and powerful approach explaining academic achievement as well as educational choices and attainment. Recently, attention to the multiplicative term of expectancy and value beliefs has increased. Trautwein et al. (2012) reported a detrimental effect of high task value when expectancy beliefs were low. We aimed to replicate and extend their study by using a large, representative sample of students attending upper secondary school in the German federal state Schleswig-Holstein (N = 3367). Following Trautwein et al. (2012), we applied latent interaction modelling to test whether the predictive value of expectancy value interactions differs for grades, final examinations, and standardized test scores as measures of achievement in two domains. We took the multi-dimensional structure of task value into consideration, analyzing the four components (attainment, intrinsic value, utility and cost) separately. Both a verbal and a non-verbal domain (English as a foreign language and mathematics) were investigated. Overall, the results supported those of Trautwein et al. (2012). However, our findings suggested measure- and domain-specific differences when using expectancy value beliefs and their interactions to predict academic achievement. Interaction terms predicted final examination results in both English and mathematics. Further, interaction effects were significant for grades in English but not mathematics. In general, effect sizes of multiplicative terms were small, especially in contrast to expectancy beliefs. Findings are discussed regarding the practical and conceptual importance of the multiplicative term in expectancy value theory applied in an educational setting.

多维教育在大学和职高中的应用对比研究

随着中国与世界其他国家的交流越来越频繁,英语作为一种重要的交流工具,彰显的作用越来越明显。在语言知识的教学过程中,英语教学取得了举世瞩目的成就。但是,也有很多多维。在传统的英语教学过程中,以考试为中心的教学模式的弊端主要体现在学生英语水平的实际应用和学生自身能力的提高上。因此,在英语教学过程中,如何改变教学观念,深入探索课堂教学,以提高英语教学效率,从而全面发展学生的自主性、主体性和英语能力已经成为当代英语教学改革过程中的一个主要多维。这项研究的目的是为职高英语课程构建一个多维互动式教学模型。通过改变教学方法,我们努力提高学生的英语学习能力,培养学生对语言技能的综合利用,并促进深度学习。     

Dynamics and manipulation of ferroelectric domain walls in bismuth ferrite thin films

Ferroelectric domain walls differ from domains not only in their crystalline and discrete symmetry, but also in their electronic, magnetic, and mechanical properties. Although domain walls provide a degree of freedom to regulate the physical properties at the nanoscale, the relatively lower controllability prevents their practical applications in nano-devices. In this work, with the advantages of 3D domain configuration detection based on piezoresponse force microscopy, we find that the mobility of three types of domain walls (tail-to-tail, head-to-tail, head-to-head) in (001) BiFeO₃ films varies with the applied electrical field. Under low voltages, head-to-tail domain walls are more mobile than other domain walls, while, under high voltages, tail-to-tail domain walls become rather active and possess relatively long average lengths. This is due to the high nucleation energy and relatively low growth energy for charged domain walls. Finally, we demonstrate the manipulation of domain walls through successive electric writings, resulting in well-aligned conduction paths as designed, paving the way for their application in advanced spintronic, memory and communication nano-devices.     

任务型学习在英语泛读的应用

根据Ellis的“输入与互动假设”理论,倡导在英语泛读教学过程中开展“对话性互动”和“变化性互动”,应用“任务型学习”,并结合课堂实践,设计了教学实例,这一实践实现了“以学生为主体,教师为主导”的新教学模式,具有多元性、人文性、合作性和反馈性的特点。     

从“文斗”到“武斗”:礼法约束下“斗秧歌”田野调查

以海阳大秧歌中的民俗武术活动“斗秧歌”仪式为个案,运用田野调查等方法,从民俗学视角对“斗秧歌”的过程及民俗语境进行分析。认为:海阳大秧歌吸收了军事武术中的兵法谋略与民间武术技术动作,族群生存斗争与比武较技是“斗秧歌”吸收武术元素的重要动因,其逻辑形式表现为礼法约束下由“文斗”到“武斗”的递进,“文斗”体现兵法谋略智慧,武术是“武斗”的主要支撑力量。“斗秧歌”受到礼法约束,以强化乡间社会秩序的稳定,反映了中国传统社会治理中的礼法并施思想。剖析其民俗语境发现,“斗秧歌”是族群生存抗争的仪式手段、护卫生存环境的民间演习、展示个人魅力的艺术舞台,也是地域武术传播的民俗载体。武术与“斗秧歌”之间的融合互动关系,显示武术与民俗活动深厚的历史渊源及武术具有的多元价值属性。
