Students’ knowledge about the value of discussions for teaching and learning

We are particularly interested in looking at teaching and learning from students perspectives. Focussed interviews and written responses from a number of linked investigations with middle-school and tertiary students highlighted that students perceive discussion to be a valuable teaching -- learning technique. This paper provides text extracts, organised into six key themes, to illustrate students understandings about how discussion helps them to learn. We conclude that, across the whole participant group, knowledge about the various potentials of discussion for learning is wide ranging. However, at the individual level, some students perspectives appear limited. We propose that specific attention to enhancing students pedagogical knowledge about techniques such as discussion should accompany subject matter instruction.     

The Eye of Suffering: Reflections on <Emphasis Type="Italic">The Passion of the Christ</Emphasis>

This reflection on Mel Gibsons Passion views the movie as myth and takes an archetypal perspective on the role of suffering in the deep transformation of both person and God. My approach is intentionally in contrast to most liberal reviewers who have taken issue with the movie from historical perspectives.     

-autonomous Lattices

-autonomous lattices are the algebraic exponentials and without additive constants. In this paper, we investigate the structure theory of this variety and some of its subvarieties, as well as its relationships with other classes of algebras.     

The Primary and Secondary Factors That Promote Destructive Personalities

The ability of behavioral scientists to assist society deal competently with destructive behavior relies upon a recognition of its causes. Despite the pervasiveness of violence in American society, the roots of destructiveness are still poorly understood. Five primary and five secondary factors found in the developmental histories of people who have become involved in serious destruction are identified and discussed. The confluence of these factors in the steps toward destructive acts are traced.

Pre-stimulus alpha predicts inattentional blindness

Pre- and post-stimulus oscillatory activity between 8 and 12 hertz, referred to as the alpha-band, correlates with conscious visual awareness of stimuli across a variety of psychophysical tasks. Within an EEG-adapted inattentional blindness task, the current study sought to examine whether this relationship holds for conscious awareness of stimuli under conditions of inattentional blindness. Noticing rates of the task-irrelevant unexpected stimulus were correlated with a significant decrease in alpha power over bilateral parietal-occipital areas during the pre-stimulus interval, and a significant decrease in alpha power over parietal-occipital regions in the right hemisphere during the post-stimulus interval. Findings are taken to imply alpha-band neural activity represents a valid correlate of consciousness that is not confounded by task relevancy or the need for report.
