In this article, the author challenges the validity and usefulness of the concept of "paradigm," as this term has been used in the social sciences generally, and specifically in the debates over research methods. He emphasizes that in criticizing what he sees as the misuse of the paradigm concept, he is not arguing for dismissing or ignoring…

Cultural-historical activity theory (CHAT), founded on the seminal work of Vygotsky and evolving in the subsequent work of Leont'ev and Engestrom, continues to emerge as a robust and increasingly widely used conceptual framework for the research and analysis of the complex social mediation of human learning and development. Yet there remains…

Although the "K"-means algorithm for minimizing the within-cluster sums of squared deviations from cluster centroids is perhaps the most common method for applied cluster analyses, a variety of other criteria are available. The "p"-median model is an especially well-studied clustering problem that requires the selection of "p" objects to serve as…

A cyclical conditional maximum likelihood estimation procedure is developed for the multidimensional unfolding of two- or three-way dominance data (e.g., preference, choice, consideration) measured on ordered successive category rating scales. The technical description of the proposed model and estimation procedure are discussed, as well as the…

For researchers, committed to a research problem, finding meaningful answers is a process of careful weighting and interpreting what is actually found as an outcome of their mode of inquiry in reference to initial intentions and research goals. Particularly in doing qualitative research in/on teaching researchers have recognised the need to…

The commentary argues for an understanding of how texts are put together that accounts for multimodality and draws on children's ways of being and doing in the home, their "habitus". It focuses on identities as socially situated. It argues that it is important to trace the process of sedimenting identities during text production. This offers a way…

This article critically explores the value of ethnography for enhancing context-sensitive approaches to the study of academic writing. Drawing on data from two longitudinal studies, student writing in the United Kingdom and professional academic writing in Hungary, Slovakia, Spain, and Portugal, the author illustrates the different contributions…

Individuals often estimate the probability of future events by the ease with which they can recall or cognitively construct relevant instances. Previous research has not precisely identified the cognitive processes mediating this "availability heuristic." Two potential mediators (imagery of the event, perceived reasons or causes for the…

Social sciences research is entrenched with particular values, beliefs, norms, and practices that students, faculty, and researchers reproduce over time. In this article, the author argues for extending what counts as research within the social sciences to be more inclusive of differing methodologies and writing genres. Using personal narrative,…

Examined the problem-solving performances of novices (11 undergraduates) and experts (9 graduate students and instructors), comparing them in terms of background expertise and problem-solving success. Also examined problem-solving behaviors reported in other domains and determined whether or not genetics is a fruitful area for problem-solving…

Views information as residual or catalytic form of energy which regulates other forms of energy in natural and artificial systems. Parallel human information processing (production systems, algorithms, heuristics) and information measurement are discussed. Suggestions for future research in area of parallel information processing include a matrix…

The modern history of biology shows how Darwin's selectionist theory has replaced instructionist theories in explaining the operations of living things: first with inheritance through the gene pool of the 1850s, and second with the replacement of a template theory of immune system function in the 1960s. Today scholars in several disciplines…

One solution to the problem of getting expert knowledge into expert systems would be to endow the systems with powerful learning procedures that could discover appropriate behaviors by observing an expert in action. A promising source of such learning procedures can be found in recent work on connectionist networks, which are massively parallel…

Following a brief discussion of the lack of definition and cohesion in the social studies and the curriculum, the paper argues that the reflective inquiry rationale has had the most significant influence of all the alternative rationales for the field and its curriculum. The paper presents its case in four basic sections. The first section,…

Reviews the problems of classifying gaming techniques and suggests a heuristic approach as one solution. Definitions of simulation, models, role, and game and play are discussed to help develop a classification based on a technique called gaming simulation. (Author/LRW)
