Teacher practices associated with students' sense of the classroom as a community

Data from observations of 232 elementary classrooms and from student questionnaires were used to test a model linking teacher classroom practices to students' sense of the classroom as a community (assessed by questionnaire) through intermediate effects on students' classroom behavior. The model was generally confirmed and showed that teacher practices (emphasis on prosocial values, elicitation of student thinking and expression of ideas, encouragement of cooperation, warmth and supportiveness, andreduced use of extrinsic control) were related to student classroom behaviors (engagement, influence, andpositive behavior), which, in turn, were related to students'sense of community. Teachers' encouragement of cooperative activities appeared to be particularly important in this sequence. The appropriateness of the model was tested for schools serving populations that were both high and low in level of poverty, and all estimates of path coefficients were found to be invariant across these groups.

Brain imaging: Applications in psychiatry

For more than a century psychiatrists have suspected neuropathology in patients with mental illness. In the last decade there have been developed several technologies that are capable of looking at both neuroanatomy and neurophysiology in the brains of living humans. First, x-ray computerized axial tomography led the way in visualizing the living brain, and now magnetic resonance imaging allows brain structure to be shown with even more clarity. Brain electrical activity mapping allows computerized maps of electrophysiological activity to be visualized in a way never before possible. Nuclear medicine has provided the means of looking at various metabolic and neurochemical parameters in the living brain. These include regional cerebral blood flow studies using xenon¹³³, single photon emission tomography, and positron emission tomography. Psychiatrists are cautiously optimistic that these various brain imaging technologies will be important new tools in continued exploration of the causes of mental illness and ultimately may lead to more effective treatments.
