This article is concerned with how computer science, and more exactly computational complexity theory, can inform cognitive science. In particular, we suggest factors to be taken into account when investigating how people deal with computational hardness. This discussion will address the two upper levels of Marr's Level Theory: the computational…

In the present article, we articulate three assumptions underlying theories proposing that restructuring processes play a key role in insightful problem solving: representational difficulty, representational change, and discontinuity in solution processes. We argue that these assumptions need empirical validation to justify the proposition of…

How is knowledge represented and organized in the mind? What role does it play in discourse comprehension and interpretation? What are the exact mechanisms whereby knowledge-based processes are utilised in comprehension? These are questions that have puzzled psycholinguists and cognitive psychologists for years. Despite major developments in the…

Suggests that knowledge organization must encompass theories that focus on the more fundamental and less technical view and raises the questions of epistemology and general linguistic theory. Focuses on the meaning aspect of language and the terminological aspect of knowledge organization. Considers theories of terminology, language and meaning,…

Argues that discussing theories, including their origin, development and replacement by other theories, can help students understand both the objective and subjective aspects of the scientific process. (DDR)

Describes six divergent forms of constructivism in providing an overview of constructivist theory. Suggests a scheme for characterizing constructivist writing on the basis of its relative emphasis on personal versus social construction of knowledge, and objectivist versus relativist views of the nature of science. Contains 31 references. (DDR)

Argues that some forms of constructivism propose an epistemological idealism with a concomitant relativism, while other forms are explicitly opposed to such positions. Explains that all forms of constructivism are often presented as being relativistic. Contains 31 references. (DDR)

Examines central parts from the first two papers in this journal by Peter Slezak criticizing the "sociology of scientific knowledge". Considers some of the main philosophical issues raised by sociologists of science. Contains 87 references. (DDR)

Constructs the philosophical background and underpinnings of the Science Education Portfolio Instruction and Assessment (SEPIA) project. Explains that students must develop skills in order to participate in epistemic interchanges. They must also be provided opportunities and materials to develop those skills. Contains 29 references. (DDR)

Distinguishes between psychological constructivist and social constructivist groups. Explains the reasons for the growing acrimony in debates between the two groups. Discusses social constructivist accounts of the causes of belief in science. Contains 43 references. (DDR)

Addresses two research questions pertaining to the search for students' potential alternate conceptions within the history of science and the possibility of helping students overcome these misconceptions through historical experiments. Contains 19 references. (DDR)

Argues that constructivist science education works with an unsatisfactory account of knowledge which affects both its account of the nature of science and of science education. Includes a brief survey of realism and anti-realism in science. Contains 42 references. (DDR)

Discusses and criticizes a number of constructivist positions in education that are based on distinctions between the metaphors of "finding" versus "making" for the obtaining of new knowledge. Discusses what is of value in constructivism and what is ill-founded baggage. Contains 25 references. (DDR)

Distinguishes educational constructivism, which has its origins in the theories of children's learning, from constructivism in the philosophy of science and from constructivism in the sociology of science. Notes the evolution of educational constructivism and identifies some theoretical problems concerning constructivist teaching of science…

Provides evidence that demonstrates the inadequacy of Piagetian constructivist theory in explaining the complexities of children's early learning. Outlines an alternative nativist theory of cognition and discusses the implications for science education. Contains 60 references. (DDR)
