Web-enhanced case-based activity in teacher education: a case study

Recent work in case-based reasoning (CBR) reinforces the importance of situated learning, expert cases, and authentic tasks and activities for novice learners. As novices engage CBR environments, they apprentice in the experts’ practices while developing the understanding, knowledge and skill of a given community. This study examined how prospective teachers, as novices in a semester-long course, engaged and developed expert-like practices using the case knowledge of experienced teachers who teach with technology. By engaging experienced teachers’ knowledge and skill via Web-enhanced cases, prospective teachers refined their understanding of teaching culture and teaching with technology as they transitioned to the teaching community.     

Phonological awareness and reading speed deficits in reading disabled Greek‐speaking children

There is evidence that phonological awareness skills secure decoding ability and that phonological deficits underlie failure to acquire adequate word recognition. Slow word‐reading rate may be an additional defining characteristic of reading disability. The present study aimed to investigate whether: (1) reading disabled (RD) Greek‐speaking children showed reading accuracy and reading speed deficits relative to chronological age‐matched controls (CAC) and reading age‐matched controls (RAC); (2) they showed phonological deficits relative to the two control groups who do not present reading difficulties; and (3) they showed reading comprehension deficits over and above any word reading deficits.

Results suggested that the reading accuracy of the RD group was predictably weaker than that of the CAC group but equivalent to that of the RAC group. However, the reading speed of the RD group was significantly slower than the RAC group, who showed the same single word reading speed as the CAC group.

Slow and laboured decoding was found to compromise the reading comprehension of the RD group, whose listening comprehension performance was as good as the two other groups. The RD children performed poorly on phonological awareness tasks and naming speed. Naming speed was not an independent core feature of reading difficulties in the Greek language but was associated with a general phonological deficit.

It is recommended that diagnostic assessments for children with reading difficulties in Greek should include phonological awareness, single word reading and pseudoword reading tasks that measure both accuracy and speed.     

论义务教育均衡发展中的决策和利益表达

义务教育均衡发展是我国现代化均衡发展战略的组成部分,利益调整是其最终归宿,其决策必须建立在利益相关人的利益表达基础上。我国义务教育均衡发展前期的决策和利益表达出现了分离,这和利益表达沟通中介的功能缺失相关,更深层次则与我国现代化是世界现代化的＂后发部分＂特点相关。义务教育均衡发展要实现决策和利益表达的结合,必须进行教育决策模式改革,实现利益主体的回归。     

办园体制改革对幼儿园教师的影响

以苏南某幼儿园的两次办园体制改革为基础,本研究对该园园长在改制前后的工作、生活等进行了个案跟踪与叙事。结果显示:在体制变迁中,幼儿教师在依附政府决策的同时,也进行了多种形式的反抗。政府变卖幼儿园本质是对教师劳动的社会贡献力的忽视。

论等级顺序理论对形态阻遏的阐释力

英语中存在多种阻遏现象,形态阻遏是其中的一种,它包括词项对派生词和曲折词缀生成词的阻遏。等级顺序理论认为在英语中派生和曲折过程是按等级顺序进行的,其顺序与形态构词过程有关。试用等级顺序理论来揭示形态阻遏是如何产生的,指出等级顺序理论对形态阻遏有一定的阐释力,并对该理论不足之处提出的修正。     

Family and social risk,and parental investments during the early childhood years as predictors of low-income children's school readiness outcomes

Using data from the National Early Head Start (EHS) Research and Evaluation Project (N = 1851), the current study examined relations among cumulative family and social risk, assessed during infancy and the preschool years, and children's prekindergarten achievement, self-regulatory skills, and problematic social behavior, testing if these associations were mediated through two sets of family processes–responsive parenting practices and the provision of language stimulation and literacy practices. Structural equation modeling results highlight the significance of the timing of children's experience of risk in predicting school readiness competencies. Risk exposure during infancy was observed to be most detrimental for children's school readiness skills and was partially mediated by risk exposure during the preschool years and family processes, assessed during toddlerhood and the preschool years. Moderation analyses revealed no difference in the strength of relationships among the study variables by EHS assignment or by race/ethnicity.     

Critique in academic disciplines and active learning of academic content

This article argues for increased theoretical specificity in the active learning process. Whereas constructivist learning emphasizes construction of meaning, the process articulated here complements meaning construction with disciplinary critique. This process is an implication of how disciplinary communities generate new knowledge claims, which is comprised by an interaction of roles – authors construct claims and peers critique them. Because disciplinary critique drives and shapes generation of knowledge claims, specialized features of these claims both justify and define their meaning. Here science is offered as an example, in which critique drives measurement of key concepts, thereby anchoring their meaning in operational definitions. The account of active learning proposed sheds new light on both historical and contemporary characterizations of active learning in terms of taking a critical stance toward content, in which the learner questions and challenges content. Thus students, rather than teachers, should actively challenge their emerging understanding of content.
