Teacher Scaffolding: An Exploration of Exemplary Practice

While computers have increasingly been used in classroom over the last twenty years, their application has often been mundane; being merely used to reinforce existing educational practices rather than as a catalyst for educational innovation. An effective way to bring about change may be to identify instances of best practice and then study associated strategies that may be useful for teachers trying to use computers in new and meaningful ways. This study investigates strategies used by a teacher deemed to be exemplary at using computers and associated technology in her classroom. It involved observing and recording teaching sessions conducted by the teacher. This paper discusses the learning task, the children's progression through the task and the teaching strategies used. In particular, it looks for instances of teacher scaffolding as a strategy for supporting children working with computers.

目的 :观察中药方剂 (自拟降糖汤 )对控制糖尿病病情的治疗效果 .方法 :6 3例糖尿病患者分成A、B两组 .A组在常规治疗基础上加用降糖汤 ,B组予以常规治疗 ,不加降糖汤 .结果 :A组治疗后空腹及餐后 2小时血糖均明显下降 ,差异具有显著性 (P <0 0 5 ) .B组治疗前后空腹及餐后 2小时血糖无明显变化 ,差异无显著性 (P >0 0 5 ) .结论 :降糖汤对控制糖尿病患者血糖确有一定疗效     

Accounting for the Relationship Between Initial Status and Growth in Regression Models

Educational analysts studying achievement and other educational outcomes frequently encounter an association between initial status and growth, which has important implications for the analysis of covariate effects, including group differences in growth. As explicated by Allison (1990 Allison, P. D. (1990). Change scores as dependent variables in regression analyses. Sociological Methodology, 20, 93–114.[Crossref] , [Google Scholar]), where only two time points of data are available, identifying a preferred model can be difficult or impossible. In this paper we extend Allison's inquiry by considering multiple sources of the association between initial status and growth simultaneously, including measurement error but also intrinsic associations between initial status and growth. We illustrate the potential trade-offs between the change-score model specifications (models without a control for initial status) and regressor-variable specifications (with a control for initial status) using simulated data.

“我→你”存在关系中的道德作为论

当前道德状况的恶劣,在于越来越多的"我"信守"他→社会"式行动模式和道德评价模式,使我的道德不在场,由此形成我对道德的不作为,这种不作为行为本质上是我对我之存在故乡和生存家园的放逐。改变这种道德状况的有效途径是重建我的道德,使我重返以"我→你"为原初存在结构的关系世界,重建以我与自然、我与人、我与精神实体为三维向度的生存家园。我的道德的重建的主体前提是重塑我的道德意识、明朗我的道德态度、明确我的道德责任,形成我的道德在场坚守能力,在日常生活中坚持不懈地展开道德作为;我的道德作为所应该遵循的行为准则是:我所不欲勿施于你,我之所欲亦施于你;我欲立而立你,我欲达而达你。     

谈《红楼梦》中人物"美丑相衬"的艺术效应

《红楼梦》作者十分娴熟地掌握了美丑对立统一的美学原则,在人物形象的塑造中大量运用了以丑衬美、以“陋”衬美、丑中见美、美中寓丑等多种美丑相衬与转化的艺术技巧,让笔下众多人物外表与性格复杂斑斓,美丑互映,从而使人物形象更具有鲜明的个性与深刻的共性,为中外文学画廊树立起一群夺目生辉的不朽典型形象。
