The complexities of public education today require new, distributed models of school leadership in which teachers play a central role. The most effective teachers assume leadership roles as instructors and professional colleagues. In this article, we propose a framework for developing teacher leadership that consists of four intersecting domains:…

This ethnographic, cross-cultural study used a dialogic, sociolinguistic framework to describe learning processes in portraits of three immersion summer camps in the eastern US. Using the data collection techniques of in-depth interviewing, participant observation and textual analysis, the study examined the process of second language learning and…

An expansion of three lectures on schema theory given at the University of Alberta as part of the MacEachran Memorial Lecture Series, this book is intended for students and researchers interested in the schemata that organize knowledge of stories, events, and scenes, and to serve as an introduction to the elements of schema theory and the…

This brief paper argues that structural analysis--an extended form of cognitive task analysis--demonstrates that both domain dependent and domain independent knowledge can be derived from specific content domains. It is noted that the major difference between the two is that lower order rules (specific knowledge) are derived directly from specific…

Reviews research which indicates that the knowledge structures of professional literatures are systematically different from those of scientific literatures, and that these differences are consistent with theories of scientific knowledge such as those advanced by Kuhn, Polyani, and Zinman. A list of 104 references is included. (MES)

Presents evidence from the memory development literature showing why strategies and metaknowledge are not sufficient factors to account for memory development. Summarizes current research on the influence of the general knowledge base, including general world-knowledge and domain-specific knowledge and procedures. Discusses questions that must be…

Examines definitions of information and highlights a definition that is independent of any specific discipline. Topics include processes; a hierarchical model of information transmission; information representation; information theory; belief and knowledge; and errors, misinformation, and bad data.

Understanding knowledge is the first step in managing it effectively. Twelve guiding principles and the core competencies of knowledge can help organizations make the most of their knowledge assets. (JOW)

A study of 192 undergraduates attempted to clarify why giving people more occupational information often results in decreased differentiation in career choice. Making the constructs more personally meaningful to students appeared to reverse the decrement in differentiation. (JOW)

Discusses various views of domain-specificity. Argues that it is time to move beyond an acknowledgment that constraints on the way knowledge is represented influence the way in which new learning proceeds. Directions for future research are pointed out. (RH)

Investigates the evidence that the imperfect performance in forward search of 36 children aged four and five years resulted from unstable execution of the correct component processes. Evidence suggests that five-year-olds engaged in forward search, but four-year-olds used only a rudimentary form of forward search. (RJC)

Examines answer selection within the framework of QUEST, a psychological model of question answering that specifies how knowledge structures are searched during question answering. Examines whether both "legal" and "illegal" answers were activated during the search. Finds support for QUEST's arc-search procedures associated…

Replies to commentaries by Mandler (1988) and Rochat and Striano (1988), focusing on Mandler's comments. Maintains that their disagreements are the result of deep meta-theoretical differences regarding a representational theory of mind rather than misrepresentations of fact. Discusses how their meta-theoretical differences result in several basic…

Discusses the concept of schema and the role this concept plays in educational practice. Traces the historical development of the concept and how it came to be taken for granted that schemata exist. Suggests a return to a more phenomenological approach to learning and knowledge formation. (SLD)

This study describes how medical and nursing students develop their conceptions and understanding of science during 3 years of study at the academic level. The point of departure is the students' commonsense conceptions at the start of the undergraduate programme, which are seen as alternative ways of thinking to the more theoretical explanatory…
