The present study examined the effects of the clock-light cueing device as part of a paradigm designed to control classroom behavior. The results indicated that the clock-light cueing device is an effective instrument in helping to reduce the time spent in disruptive behavior in the classroom. The results further indicated that decreasing the time spent in undesirable behaviors in a classroom does not necessarily decrease the frequency of these behaviors. Implications for treatment and further research are discussed. 相似文献

The relation between particle size and the degree of polarization of the Tyndall beam created by suspension of non-uniform particulate substances was investigated for three materials (silica, granite, and calcite) ranging in size from one to fifty microns. The degree of polarization was found to be a function of the arithmetic mean diameter of the material. The optical property of birefringence was also found to be a determining factor although its effect was not studied quantitatively. It is shown that by combining the equation expressing the relation between particle size and strength of Tyndall beam with the mathematical relation between degree of polarization and particle size, an indirect method of obtaining a complete definition of particle size is given. Particle size values calculated from observed Tyndall readings and measurements of polarization were found to be within approximately ten per cent. of observed values. 相似文献

Summary Was the project successful in assisting teachers to reform their biology teaching? The answer appears to be a qualifiedyes. Although teachers changed how they taught biology, they did not necessarily adopt the model as originally conceived by the
project. Teachers used materials they developed in ways that increased student involvement in learning and decreased direct
teacher instruction. Teachers taught primarily from the units they developed, and they borrowed instructional ideas and lessons
from other units which fit their instructional style and curriculum. Teachers did not, however, adopt complete instructional
units developed by other teachers for use in their classroom. 相似文献

This article examines issues related to minority teachers in New York City. Although increasing proportions of teachers hired in the last decade are black, Hispanic, or Asian, the gap between proportions of pupils and teachers remains due to increases in minority pupils. There are strong correlations between proportions of teachers and pupils in districts within racial and ethnic groups. The converse is also true; there are strong negative correlations between black and Hispanic teachers, for example, and percent of white and Asian pupils. Districts with larger proportions of minority pupils tend to have more emergency new teachers, fewer fully certified teachers, and fewer experienced teachers. Only 58% of the new black or Hispanic teachers, compared with 82% of white teachers, indicated they intend to remain in teaching after five years. Interviews with personnel directors suggest there are no systematic constraints on selection processes. New minority teachers queried about their job-search practices suggest somewhat more frustration with the process and less use of local leads than white teachers. Together these data suggest that the ability to increase the number of minority teachers is a more complex problem than recruitment and training. Moreover, minority pupils do not appear to have equal access to experienced and fully qualified teachers. 相似文献

Asthma, a chronic respiratory disease, is caused by a complex interaction between genetic and environmental variables. The intent of this article is to propose a theory that provides an explanation for the reduction of emotionally triggered asthma through treatments derived from positive psychology. The basic tenet of the theory is that physical health issues, such as asthma, can be promoted through systematic interventions that are designed to enhance the individual's sense of independence, intimacies or friendships, and/or feelings of competence. This theoretical approach is based largely on Bertrand Russell's definition of happiness and is consistent with positive psychology in that it focuses on variables that promote subjective well‐being, or a satisfying daily life. © 2004 Wiley Periodicals, Inc.

The primary interest of this study is to discover the extent to which black males are gaining or losing ground educationally
relative to other male populations. The findings of this study show that the relative difference in the percent of black and
white males with a high school or associate's degree has converged considerably, but the relative gap between black and white
males receiving a bachelor's, or graduate degree has remained constant. The data showed much upward and downward intergenerational
educational mobility for black males. Finally the data showed that the educational attainment of black males was significantly
associated with their age, their father's educational attainment level, and the size of the place in which they lived at age
