Constructivism is an approach to knowledge and learning that focuses on the active role of knowers. Sanchez and Loredo propose a classification of constructivist thinkers and address what they perceive to be internal problems of present-day constructivism. The remedy they propose is a return to the genetic constructivism of James Mark Baldwin, Jean Piaget and Lev Vygotsky. In this article we first raise the question of whether thinkers like Baldwin, Vygotsky, Maturana and Varela are adequately depicted as constructivists, and subsequently argue that constructivism is caught in an overly epistemic version of the subject/object dichotomy. We then introduce a genetic logic that is not based on the Hegelian dialectics of negation and mediation, but rather on the idea of the recursive consensual coordination of actions that give rise to stylized cultural practices. We argue that a genuinely genetic and generative psychology should be concerned with the multifarious and ever-changing nature of human “life” and not merely with the construction of knowledge about life. Relevance: The article deals with perceived “internal” problems of constructivist approaches and proposes a genetic and generative psychology that is centrally concerned with human life-as-lived and not merely with life-as-known. The article furthermore raises the question whether key thinkers like Vygotsky, Maturana and Varela and are adequately depicted as constructivists.

Key words: Constructivism, genetic logic, generativity, expressivism, enactivism.

My colleagues and I have begun to build a model of the development of young infants’ physical reasoning. The model is based on the assumption that infants are born not with substantive beliefs about objects (e.g., intuitive notions of impenetrability, continuity, or force), as researchers such as Spelke and Leslie have proposed, but with highly constrained mechanisms that guide the development of infants’ reasoning about objects. The model is derived from findings concerning infants’ intuitions about different physical phenomena (e.g., support, collision, and unveiling phenomena). Comparison of these findings points to two developmental patterns that recur across ages and phenomena. We assume that these patterns reflect, at least indirectly, the nature and properties of infants’ learning mechanisms. In this review, I describe the patterns and summarize some of the evidence supporting them.

Connections among Varela’s theory of enactive cognition, his evolutionary theory of natural drift, and his concept of autopoiesis are made clear. Two questions are posed in relation to Varela’s conception of perception, and the tension that exists in his thought between the formal level of organization and the Jonasian notion of the organism.

Excerpt: Inthe French language, the verb vivre means both “to be alive” (Leben) and “to have an experience, to feel something” (Erleben): it is neutral with respect to the distinction between the transitive life that we call consciousness, and the intransitive life of organisms that merely keep themselves alive. In this text, we put forward the hypothesis that this neutrality, far from being a simple accident of language, is highly revealing as to the primordial status of life; it thus indicates the direction that a phenomenology of life should take. The question that a phenomenology of life has to confront is thus the following: what is the primordial meaning of life such that it precedes the distinction between intransitive and transitive life, and thereby makes this distinction possible? In other words: what is life such that the possibility of consciousness is grounded therein? From the moment we consider that consciousness is basically characterized by intentionality, primordial life must already contain the germ of a fundamental transitivity where intentionality can be grounded; it follows from this that the question of the Being of intentionality, and that of the mode of Being of life, are one and the same question.

At a conference last month called Investigating the Mind, held here at the Massachusetts Institute of Technology, neuroscientists and Buddhist scholars discussed attention, mental imagery, emotion, and collaborations to test insights gleaned from meditation.

Social Systems Theory has a long and distinguished history. It has progressed from a mechanical model of social processes, to a biological model, to a process model, to models that encompass chaos, complexity, evolution and autopoiesis. Social systems design methodology is ready for the twenty-first century. From General Systems Theory’s early days of glory and hubris, through its days of decline and disparagement, through its diaspora into different disciplines, systems theory is today living up to its early expectations.

Key words: systemic model, roots of systems theory, branches of systems theory, history of systems theory.

Constructivism is an important theory of learning that is used to guide the development of new teaching methods, particularly in science education. However, because it is a theory of learning and not of teaching, constructivism is often either misused or misunderstood. Here we describe the four essential features of constructivism: eliciting prior knowledge, creating cognitive dissonance, application of new knowledge with feedback, and reflection on learning. We then use the criteria we developed to evaluate five representative published articles that claim to describe and test constructivist teaching methods. Of these five articles, we demonstrate that three do not adhere to the constructivist criteria, whereas two provide strong examples of how constructivism can be employed as a teaching method. We suggest that application of the four essential criteria will be a useful tool for all professional educators who plan to implement or evaluate constructivist teaching methods.

Between 1984 and his death in 1998, German sociologist Niklas Luhmann developed a comprehensive theory of what he called autopoietic or self-referential systems. He worked out this approach both at the level of a social system as a whole and at the level of various social subsystems, such as state, economy, science, religion, education, art, family, and – the concern of the present article – law. My particular topics in this critical introduction to Luhmann’s theory are (a) its relation to more standard legal theory, (b) foundational or self-referential problems in law, and (c) the problem of law’s relation to other social spheres, especially politics and the economy.

Key words: luhmann, autopoiesis, social systems, self-reference.

Constructivism is a theory of learning, which claims that students construct knowledge rather than merely receive and store knowledge transmitted by the teacher. Constructivism has been extremely influential in science and mathematics education, but much less so in computer science education (CSE). This paper surveys constructivism in the context of CSE, and shows how the theory can supply a theoretical basis for debating issues and evaluating proposals. An analysis of constructivism in computer science education leads to two claims: (a) students do not have an effective model of a computer, and (b) computers form an accessible ontological reality. The conclusions from these claims are that: (a) models must be explicitly taught, (b) models must be taught before abstractions, and (c) the seductive reality of the computer must not be allowed to supplant construction of models.

Key words: computer science education, dominant theory, idiosyncratic version, accessible ontological reality, ective model, theoretical basis, seductive reality, store knowledge, mathematics education
