Action research was used as a means of introducing adult learning principles into the teaching of an optometry department. The department took as an overall development theme the move from teacher-directed to leamer-directed activities. Pilot studies were used as a mechanism for trialling particular innovations. Lessons learnt from the pilot studies are shared with the remainder of the department for incorporation into other subjects, thus evolving a mechanism for departmental change. The paper shows how change occurred by reporting briefly two pilot studies as examples. The first used group project teams to prepare class presentations for specified topics. Some novel presentation methods were used by the student teams. Peer assessment was introduced into this subject in the second cycle of the pilot study as a result of feedback from the first cycle. The second pilot study introduced active learning methods in place of lectures. 相似文献

Audiogenic seizures in mice: Asymmetries of the preconvulsive running pattern and subsequent seizure
Asymmetries in the progression of unilaterally and bilaterally induced audiogenic seizures were examined in DBA/2J and SJL/J mice. Both strains were found to exhibit consistent asymmetries in direction(s) of running as well as in the side of fall during a convulsion. This correspondence suggests that the bursts of running are an integral part of an audiogenic seizure. The incorporation of information on asymmetries of the locomotor prelude in future studies should prove valuable for understanding the physiological mechanisms of audiogenic seizure. 相似文献

Attitudinal data were collected for a sample of 492 parents and public school children before implementation of a metropolitan desegregation plan and for 2 years after implementation. The variables measured included racial attitudes, feelings out desegregation, and school-related attitudes. There were small but significant changes on 7 of the 11 measures, with most of the changes occurring during the first year. There were race and grade-level differences on some of the variables before desegregation, but race and grade level were generally not related to changes over time.This research has been supported by a grant from the Rockefeller Foundation, Division of Social Sciences. 相似文献

Working and Playing Together: Prediction of Preschool Social-Emotional Competence from Mother-Child Interaction 总被引:2,自引:0,他引:2
The impact of mother-child interaction on preschoolers' social-emotional competence was evaluated. Twenty-five girls and 23 boys (mean age = 44 mos) and their mothers were videotaped performing four play/teaching tasks. Preschool teachers completed the Baumrind Preschool Behavior Q-Sort and the Behar Problem Behavior Questionnaire. Mother-child interaction aggregates represented task orientation, positive emotion, and allowance of autonomy/reliance on mother. Results indicated that specific maternal interaction aggregates coherently predicted the children's Positive Social Behavior, Assertiveness, and Sadness in the preschool setting. Child aggregates were less effective predictors of teachers' ratings. Several gender differences in the prediction of social-emotional competence were found (e.g., maternal allowance of autonomy predicted girls' sadness, but boys' sadness was predicted by their own negative emotion). These findings' contributions to the parent-child literature are discussed. 相似文献

Play as the Leading Activity of the Preschool Period: Insights from Vygotsky, Leont'ev, and Bakhtin 总被引:1,自引:0,他引:1
Cultural-historical psychology identifies play as the leading activity in preschool development. Vygotsky's (1967, 1978) seminal work outlined two categories of leading influences: play makes a foundational contribution to the development of semiotic mediation, and it involves active appropriation of social roles and rules and other integral aspects of social organization. Leont'ev's (1981) concept of appropriation and Bakhtin's (1981) concepts of heteroglossia and ideological becoming are used to elaborate and extend Vygotsky's original work, particularly with regard to creativity in preschool play. The paper concludes with a consideration of the pedagogical implications of the cultural-historical view on play, including the use of play to cultivate understanding of the arbitrary nature of signs and the appropriation of the social roles and organizational patterns of society. 相似文献
