Piaget defines intelligence as adaptation, or the ability to maintain a balance between stability and change, or, in his own words, between assimilation and accommodation. When people assimilate the world to their current knowledge, they impose their order upon things. This momentary closure is useful to build “invariants” that lend existence to the world, independent of immediate interaction. In accommodation, people become one with the object of attention. This may lead to momentary loss of control, since fusion loosens boundaries, but allows for change. I choose the domain of perspective-taking to illustrate how this alternation between assimilation and accommodation punctuate individuals’ interactions with the world. I show that the ability to move away from one’s own standpoint, and to take on another person’s view, requires the construction of cognitive invariants: a recasting of the world’s stabilities that transcends any given viewpoint. I conclude that separation is a necessary step toward the construction of a deeper understanding, and that adopting a “god’s eyes view” is by no means contrary to situating one’s one stance in the world.

An important tenet of constructivism is that learning is an idiosyncratic, active and evolving process. Active learning, operationalized by cognitive, metacognitive, affective and resource management learning strategies, is necessary for students to effectively cope with the high level of demands placed on the learner in a constructivist learning environment. Case studies of two students detail contrasting passive and active learning behaviours. Examples of their strategic learning behaviours illustrate that having students involved in activities such as discussions, question answering, and seatwork problems does not automatically guarantee successful knowledge construction. The nature of students’ metacognitive knowledge and the quality of their learning strategies are seen to be critical factors in successful learning outcomes.

For some years, there have been in‐service efforts to help teachers become familiar with constructivist ideas about learning, and to apply them in their science teaching. This study is a vignette of one teacher’s science teaching some time after such an in‐service activity. It explores the ways in which the teacher implemented his perceptions of constructivist ideas about learning in his teaching of a topic. The extent to which the teacher used teaching principles based on constructivism was influenced by his views of science and of learning, how he usually planned his teaching, and his confidence in his own understanding of the topic. Features of the teaching which reflect a constructivist view of learning are discussed and some problems are identified. We conclude with some reflections about in‐service programs within a constructivist framework.

It is characteristic of Heinz von Foerster’s approach to the cybernetics of cybernetics that it combines a sense of tight reasoning with the acknowledgment of fundamental ignorance. The article attempts to uncover an epistemological relationship between the reasoning and the ignorance. The relationship is provided for by a razor which reads: what can be described in relation to its composition, is described in vain in relation to its substance. The razor asks for second-order terms instead of first-order terms, or for ontogenetics instead of ontology.

Discusses the correspondence between constructivist design and the creation of multimedia projects. Argues that if students and teachers are exposed to multimedia presentations and are offered opportunities to participate in workshops or classroom activities using multimedia technology, those with interest will use it to demonstrate content area knowledge, generating further interest among faculty and students.

How may mental activity be conceptualized within the context of the epistemology engendered by cybernetics, and how may that epistemology account for imagination? I argue for an epistemology of imagination that both distinguishes imagination, understanding and interpretation, and unites all three concepts in a dialogical circle of ideas. The processes of distinguishing these concepts (and the processes that give rise to and describe mental activities) are dialogical processes. As dialogical, they fall within the scope of Heinz von Foerster’s work on second-order cybernetics.

Ralph Gehrke’s critique of an empirical study of literature reveals misunderstandings and implications which first need to be questioned. The discussion in this paper focuses an the following aspects: the constitution of the domain of literary scholarship, of concepts of literature, methods of analyzing, and questions of the self-definition of literary scholars in a media-dominated era.

This article praises the development of second-order cybernetics by von Foerster, Maturana and Varela as an important step in deepening our understanding of the biopsychological foundation of the dynamics of cognition and communication. Luhmann’s development of the theory into the realm of social communication is seen as a necessary and important move. The differentiation between biological, psychological and socialcommunicative autopoiesis and the introduction of a technical concept of meaning is central. Furthermore, Varela’s development of Spencer Brown’s ‘Laws of Form’ from a dual to a triadic categorical basic structure is considered vital. Finally the paper shows that second-order cybernetics lacks explicit and ontological concepts of emotion, meaning and a concept of signs. C. S. Peirce’s theory is introduced for this purpose. It is then shown that both theories are triadic and second order, and therefore can be fruitfully fused to a cybersemiotics.
