Phonological awareness and morphological awareness: differential associations to regular and irregular word recognition in early Korean Hangul readers

A large battery of reading related skills were orally administered to 111 4-year old and 118 5-year old Korean kindergartners, who were also tested on reading of regular and irregular Korean Hangul words. In regression equations, speeded naming was uniquely associated with reading of both regular and irregular words. In contrast, only the three measures of phonological awareness at the levels of phoneme onset, coda, and syllable uniquely explained Hangul regular word recognition, whereas only morphological awareness consistently explained irregular word recognition. Results suggest somewhat different cognitive demands for reading of regular and irregular words, based on the dual-route model, in Korean Hangul.     

Rethinking Big Science. Modest,mezzo, grand science and the development of the Bevalac, 1971-1993

Historians of science have tended to focus exclusively on scale in investigations of largescale research, perhaps because it has been easy to assume that comprehending a phenomenon dubbed "Big Science" hinges on an understanding of bigness. A close look at Lawrence Berkeley Laboratory's Bevalac, a medium-scale "mezzo science" project formed by uniting two preexisting machines--the modest SuperHILAC and the grand Bevatron--shows what can be gained by overcoming this preoccupation with bigness. The Bevalac story reveals how interconnections, connections, and disconnections ultimately led to the development of a new kind of science that transformed the landscape of large-scale research in the United States. Important lessons in historiography also emerge: the value of framing discussions in terms of networks, the necessity of constantly expanding and refining methodology, and the importance of avoiding the rhetoric of participants and instead finding words to tell our own stories.     

Electronic Course Surveys: Does automating feedback and reporting give better results?

This paper discusses an electronic course survey system designed to support evaluation of a modular programme in management taught through distance education. The scale and communication issues raised by distance education, when compounded by a complex rolling modular programme, make conventional evaluation complicated, slow and expensive. To overcome these problems, an automated evaluation process was introduced, partly based on web-based surveying, but significantly emphasising the reporting process and allowing performance indicators and complex analyses to be embedded in high quality word-processed reports, that can be quickly and easily generated after each presentation of a module. The paper discusses the system and the impact that it has had on the evaluation process, before looking to future opportunities for developments in this field, and discussing some of the implications - both expected and unanticipated - that have come out of using automation in the evaluation process.     

Judicious imitation: children differentially imitate deterministically and probabilistically effective actions

Three studies look at whether the assumption of causal determinism (the assumption that all else being equal, causes generate effects deterministically) affects children's imitation of modeled actions. These studies show even when the frequency of an effect is matched, both preschoolers (N = 60; M = 56 months) and toddlers (N = 48; M = 18 months) imitate actions more faithfully when modeled actions are deterministically rather than probabilistically effective. A third study suggests that preschoolers' (N = 32; M = 58 months) imitation is affected not just by whether the agent's goal is satisfied but also by whether the action is a reliable means to the goal. Children's tendency to generate variable responses to probabilistically effective modeled actions could support causal learning.     

Quality Learning of Physics: Conceptions Held by High School and University Teachers

This paper reports an exploration of the conceptions of quality learning held by two samples of physics teachers – final year, high school physics teachers and academics teaching first year university physics. We begin by outlining our view of quality learning, that is a view of learning in which learners take control of their own learning and engage with active construction and reconstruction of their own meanings for concepts and phenomena. This view of quality learning recognises the crucial role of the affective dimension of learning on the extent to which students engage with and maintain such constructivist and metacognitive approaches to learning. The study explored the qualitatively different ways in which individuals conceptualise quality learning in physics, using semi structured interviews that explored aspects of learning that the respondents regarded as worth fostering in their classrooms. The interview approach was a modification of the Interview-About-Instances approach that allowed the possibility of interviewees suggesting instances of particular relevance to their view of quality learning. This process resulted in a considerable quantity of rich and complex data related to a large range of aspects of physics learning. These data are summarised here, and the qualitatively different conceptions of the respondents with respect to four significant aspects of physics learning are discussed. These aspects are: doing experimental work; linking physics to the real world; students taking responsibility for their own learning and being confident/feeling proud of what you can do.     

Portfolios, Accountability, and an Interpretive Approach to Validity

How can the results of classroom-based portfolio assessment be communicated outside the classroom? How might a portfolio-based assessment system be designed and implemented? How can we evaluate the merits of portfolio-based assessments?
