This study built on a 2001–02 classroom observation study of Washington K-12 and technical schools that identified the extent of constructivist teaching activity. Results from classroom observations found that strong constructivist teaching was observable in 17 percent of the classroom lessons. The other 83 percent of the lessons observed may have contained some elements of constructivist teaching, but up to one-half had very little or no elements of constructivist teaching present. More constructivist teaching appeared to occur in alternative schools and integrated subject matter classes. There appeared to be no differences among elementary, middle/junior, and high schools in the degree to which constructivist practices were used. This study explored the relationship of this practice to student achievement, examining the percent of variance in student achievement accounted for by constructivist teaching beyond that contributed by low-income. Data came from the original observation study and from school-level standardized test scores of 4th, 7th, and 10th graders. Results found large correlations between study variables (a negative correlation between school-level family income and student achievement, large positive correlations between constructivist teaching and student achievement, and a negative correlation between constructivist teaching and school-level family income).

Recently, historians have focused on Warren S. McCul¬loch’s role in the cybernetics movement during the 1940s and 1950s, and his contributions to the develop¬ment of computer science and communication theory. What has received less attention is McCulloch’s early work in neurophysiology, and its relationship to his philosophical quest for an ‘experimental epistemology’ – a physiological theory of knowledge. McCulloch’s early laboratory work during the 1930s addressed the problem of cerebral localization: localizing aspects of behaviour in the cerebral cortex of the brain. Most of this research was done with the Dutch neurophysiolo¬gist J. G. Dusser de Barenne at Yale University. The con¬nection between McCulloch’s philosophical interests and his experimental work can be expressed as a search for a physiological a priori, an integrated mechanism of sensation.

The nature of cognition is being re-considered. Instead of emphasizing formal operations on abstract symbols, the new approach foregrounds the fact that cognition is, rather, a situated activity, and suggests that thinking beings ought therefore be considered first and foremost as acting beings. The essay reviews recent work in Embodied Cognition, provides a concise guide to its principles, attitudes and goals, and identifies the physical grounding project as its central research focus.

Der Konstruktivismus hat in der pädagogischen und erwachsenenpädagogischen Debatte der letzten zehn Jahre einiges bewegt, bisweilen gar heftige und turbulente Debatten ausgelöst. Im vorliegenden Beitrag wird der Versuch unternommen, die Potenziale dieser Debatte – ohne dieselbe im einzelnen resümieren zu können – perspektivisch auszuloten und ihrer Bedeutung für die Theorie und Praxis der Erwachsenenbildung nachzuspüren. In den Blick genommen werden dabei zwei polare Spannungsfelder, welche m. E. – bewusst und unbewusst – die bisherigen Debatten bestimmen: Die Spannung zwischen „Erkenntnis und Handeln“ einerseits und die Spannung zwischen „innerer und äußerer Systemik“ andererseits.

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.

Notions of embodiment, situatedness, and dynamics are increasingly being debated in cognitive sci ence. However, these debates are often carried out in the absence of concrete examples. In order to build intuition, this paper explores a model agent to illustrate how the perspective and tools of dynam ical systems theory can be applied to the analysis of situated, embodied agents capable of minimally cognitive behavior. Specifically, we study a model agent whose “nervous system” was evolved using a genetic algorithm to catch circular objects and to avoid diamond-shaped ones. After characterizing the performance, behavioral strategy and psychophysics of the best-evolved agent, its dynamics are analyzed in some detail at three different levels: (1) the entire coupled brain/body/environment sys tem; (2) the interaction between agent and environment that generates the observed coupled dynam ics; (3) the underlying neuronal properties responsible for the agent dynamics. This analysis offers both explanatory insight and testable predictions. The paper concludes with discussions of the overall picture that emerges from this analysis, the challenges this picture poses to traditional notions of rep resentation, and the utility of a research methodology involving the analysis of simpler idealized mod els of complete brain/body/environment systems.

Key words: dynamics, minimally-cognitive behavior, categorical perception

Excerpt: In their introduction to the first International Workshop on Epigenetic Robotics, Zlatev and Balkenius (2001) suggested the term epigenetic robotics to denote a new field of research resulting from the mutual rapprochement of developmental psychology and robotics, with a focus on the prolonged epigenetic developmental process through which increasingly more complex cognitive structures emerge in the system as a result of interactions with the physical and social environment.

My purpose in this paper is to show that the transcendental approach, first formulated by Kant, and then elaborated by generations of neo-Kantian thinkers and phenomenologists, provides Buddhism in its highest intellectual achievement with a natural philosophy of science. I take this highest achievement to be the Madhyamaka dialectic and soteriology,{1} which was developed in India from the second century C.E. to the seventh century C.E. by masters such as Nāgārjuna, Āryadeva, and Candrakīrti. Relevance: This is an anti-realist interpretation of quantum mechanics related to the work of Francisco Varela.

I argue that at least one of the following propositions is true: (1) the human species is very likely to become extinct before reaching a posthuman’ stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of its evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we shall one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. I discuss some consequences of this result.

Although the core of Jean Piaget’s scientific legacy is his stage model of intellectual ontogenesis and his studies of the reasoning skills that figure in those stages, his impact on education, especially American education, has been vast. Thirty years ago, his theory of cognitive development stimulated revolutionary changes in preschool and elementary school curriculum practices, and in the ensuing decades, Piagetian thought has continued to foment major changes in American education, with the whole language approach to reading instruction being a recent illustration. The aim of the present chapter is to focus attention on those aspects of Piaget’s contributions that have proven to be of greatest significance for educational psychology. The chapter begins with a biographical sketch. The rest of the chapter deals with Piaget’s views on learning. This material is divided into 2 sections. The first section presents Piagetian ideas about the relation between cognitive development and learning, and it summarizes findings from classical experiments that tested those ideas. The second section presents Piagetian ideas about instructional methodology and also summarizes findings from classical experiments that tested those ideas.
