This article examines the role of computer technology in counselor preparation. Three aspects of counselor training—acquisition of facts and theory, development of specific skills, and personal and professional development—are discussed in terms of the potential contributions and limitations of computers in training efforts.  相似文献

This investigation compares the effectiveness of two types of inservice training offered through the Arizona Portal School Program. Both methods were designed to provide teachers with positive attitudes toward activity-centered energy education. The methods differed in length and energy-related content with one course running for 5 sessions and the other for 15 sessions. The longer course placed more emphasis on content knowledge. Three types of attitudes were assessed: attitudes toward curricular change, opinions on energy concepts, and beliefs about science education. Although the longer course had a more positive effect on the participants' views of and willingness to participate in curricular change and the shorter course had a more positive effect on the participants' views of teaching activity-oriented science, both courses produced the same type of change in the participants' views of energy issues.  相似文献

Mathematics has always played an important role in the education of engineers and production managers. At the present time, the importance of mathematics has increased significantly and it is quite natural that in universities around the world engineering students are taking courses in mathematics which constitute, as a rule, a significant portion of their programme. At the same time, however, the mathematical education of the engineer is far from ideal and its improvement deserves the closest scrutiny. The present article deals with several general aspects of this problem.  相似文献

In this longitudinal study, individual differences in security of attachment at 18 months and effective autonomous functioning at age 2 years were related to the dimensions of ego-control and ego-resiliency at age 4--5 years. The kindergarten or nursery school teachers of 26 children completed California Child Q-Sorts. The children were also given a short form of the Block's laboratory battery (Banta's curiosity box, level of aspiration, motor impulse control delay of gratification, the Shure and Spivack Preschool Interpersonal Problem-solving Test, and the Lowenfeld mosaics). Following the Blocks, composited ego-resiliency and ego-control scores were derived from each data set. Children earlier classified as securely attached were, as predicted, significantly higher on ego-resiliency on both laboratory and Q-sort composites. They were also higher than anxiously attached infants on 3 independent measures of curiosity. An independently composited index of competence from 2-year tool-using measures also correlated significantly with later resiliency, as did 2-year measures of mothers' support and quality of assistance. The data provide initial links between the infant's quality of attachment, the toddler's effectiveness in a problem-solving situation, and competence during the preschool years.  相似文献
