Paul M. Bronstein Howard Neiman F. Dmitri Wolkoff M. Jov Levine 《Learning & behavior》1974,2(2):92-96
In each of two studies, rats of different ages were given one prolonged open-field trial. Animals of 21 days and older displayed within-session activity decrements, while 15-day-olds failed to habituate. The abrupt transition from a pattern of nonhabituation to one of habituation to a novel environment parallels the development of forebrain cholinergic mechanisms during the third and fourth postnatal weeks. These experiments conform to the suggestion that the 2-week-old rat is behaviorally similar to the hippocampectomized adult. 相似文献

School-based mutual support groups for low-income parents 总被引:1,自引:1,他引:0
School-based mutual support groups (MSGs) are proposed to enhance the school involvement of parents from lower socioeconomic and ethnic minority backgrounds. We present a school-based MSG format, findings from a survey regarding parent interest, and discussion of a pilot demonstration implemented in three urban elementary schools. 相似文献

Can ability and exceptional experience be accepted as substitutes for formal education in engineering? This article tells how one company developed a program of qualifications and examinations through which its more talented technicians can achieve full engineer status. The program gives the aspiring technician a continuing incentive for work towards an advanced status that is accepted without reservation by every degree engineer in the company. 相似文献

Howard B. London 《About Campus》1996,1(5):9-23
For many first-generation students, college is a transforming experience—one that requires students to play out powerful intellectual, psychological, family, and cultural dramas. Drawing on a multiyear research project he conducted with a group of colleagues, the author describes these dramas, their effects on students, and what colleges can do to help as students play them out. 相似文献

This paper presents eight guidelines that educators should follow in developing and managing undergraduate individualized studies (contract learning-type) programs. The guidelines fall under the headings (1) supplying rationales, (2) focusing on the faculty, (3) assessing faculty performance, (4) assessing student readiness, (5) assessing the costs, (6) students as researchers, (7) how much academic credit, and (8) agents of change. A main theme presented is that the student-centered focus in individualized studies programs needs to be matched by an equal regard for the faculty member. 相似文献
