Social conversation and effective discussion in online group learning

This paper studies the social talk of high school students in online discussion forums. On-task talk has generally been assessed as valuable discussion because it contributes directly to productive learning. Off-task conversation, on the other hand, is often regarded as useless and a waste of time. Should this social talk indeed be regarded as an off-task activity? Is social talk such as greeting, excusing, comforting and sharing personal feelings irrelevant to learning? This study analyzes threads and argues that social talk is interwoven with on-task talk. It is interesting to note that a substantial quantity of off-task messages served the latent function of guiding group discussion toward making progress in solving collaborative problems in a subtle and indirect manner. The power of “soft talk” embedded in off-task social conversation is explored and fully discussed.     

元认知与有效学习:原理与条件

研究者通常将元认知分为监测与调控两个子系统进行研究,并对元认知监测与元认知调控的关系及二者对个体学习的影响作用做深入探讨。基于元认知监测的学习调控是有条件的,首先是个体要有利用监测指导调控的机会,更重要的是个体的元认知监测要足够精确。通常情况下,个体的监测并不精确,但它是可以提高的。     

Supportive classrooms for Latino English language learners: Grit,ELL status,and the classroom context

Students' academic achievement is the result of the interplay between person-level and contextual factors (R. R: Greene, 2014; D. E. Hunt, 1975). Students perform better when classroom characteristics support their characteristics. The authors examine whether student perceptions of two classroom characteristics (care and control) fit with two Latino student characteristics (English language learner status and grit) in relation to their academic achievement. Using a sample of fourth- and fifth-grade Latino students from the Measures of Effective Teaching dataset (n = 3,272), the authors conducted a series of nested regression models with two- and three-way interactions between student characteristics and student perceptions of classroom characteristics. Findings revealed that grit is most strongly associated with Latino English language learners’ English/language arts achievement when students perceived that teachers used high levels of care and control. We conclude with implications for practitioners.     

Changing approaches to classroom assessment: An empirical study across teacher career stages

Research indicates that there is considerable variability in teachers' approaches to assessment resulting in different learning cultures for students. The primary purpose of the study is to examine the relationship between teachers' approaches to assessment across a set of dimensions (including their conceptions of assessment purposes, processes, fairness, and measurement theory) and career stage. The results of this paper illustrate nuanced impacts of career stage on teachers' approaches to multiple dimensions of assessment and enable the generation of assessment profiles that provide empirical support for differences in teachers’ approaches to assessment both within and between career stages.     

教育信息资源共享网络框架建设分析

随着教育现代化发展的日新月异,教学内容已经跟不上教育信息化发展的步伐,因而难以满足现代化教育对教学信息资源及教学管理的实时需求。基于现代化教育背景,从教学管理及教育信息资源共享角度出发,充分考虑教育信息资源共享的出发点与归宿点,提出构建教育信息资源共享网络框架,并对校园局部教育资源共享的网络框架示例进行了深入研究,以期为现代教育信息资源共享管理探索出新的路径,并为提高现代教育水平作出积极贡献。     

淮河流域主要农作物全生育期水分盈亏时空变化分析

利用淮河流域171个站点1971年-2010年的气象资料及作物历年生育期资料,通过作物全生育期的需水量和有效降水量计算了主要作物全生育期的水分盈亏指数.结果表明:①淮河流域小麦种植区全生育期水分盈亏指数分区平均值在-0.66～-0.43之间,各分区均呈现水分亏缺,但多年变化趋势不明显,空间分布呈明显的纬向分布特征,越往北水分亏缺越明显;②玉米种植区全生育期水分盈亏指数分区平均值在0.05～0.17之间,各区多年变化均呈增加趋势,其中北部平原夏玉米区和中部平原夏玉米区增加趋势通过了α=0.05显著性检验,分别达到0.099/10a和0.097/10a,空间分布呈西北-东南分布特征,由西北向东南增大;③沿淮及以南一季稻区水分盈亏指数平均为0.05,呈现0.024/10a的增加趋势,空间分布呈中间小两头大的分布特征.
