Research Findings: The goal of this study was to analyze children's (N = 120) evaluations about parental decisions regarding gender-stereotypic household family activities. Children at 5, 8, and 10 years of age were individually interviewed. Contrary to prevailing findings, the majority of children used stereotypic expectations and social-conventional justifications to explain parental exclusion decisions; this pattern was more pronounced for male-stereotypic than female-stereotypic activities. Overall, children's social judgments revealed age-related increases in making stereotypic choices. Boys were more likely than girls to condone stereotypic expectations regarding father–son activities than mother–daughter activities. Practice or Policy: The results are discussed in terms of (a) social–cognitive reasoning about family decision making in the home and (b) gender-stereotypic expectations between parents and children in the home context.  相似文献

Consultation is a promising approach to creating change in early childhood programs, from innovations in instructional strategies to the enhancement of global program quality. Studies of consultation effectiveness have been hampered by limited reports of implementation fidelity related to consultation procedures. This article describes the challenges of supporting and measuring implementation fidelity in a 5-state study in which community consultants followed a collaborative consultation model to enhance global quality in childcare programs. The authors consider the limitations of using a randomized experimental design to study the effectiveness of consultation and share lessons learned in their efforts to enhance treatment fidelity without compromising the basic tenets of the model or the rigorous design.  相似文献

This paper treats the problem of transmitting a Gaussian discrete-time Markov process over a time-discrete additive white Gaussian channel with noiseless feedback which is subjected to statistically unknown jamming noise (satisfying a given power constraint). The channel is used more than once during the interval between the production of successive source letters, and the jamming noise is either allowed to be correlated with the encoder output, or forced to be totally independent of it. The complete solution obtained in the paper under a minimax criterion indicates that the optimum encoder-decoder structures are linear,and the least favorable jamming noise is a Gaussian process.  相似文献

Heat transfer in laminar tube flow with convective boundary conditions and axial heat conduction in the fluid is solved exactly. The effects of the external Biot numbers and the axial conduction in fluid on the temperature distribution and the local Nusselt number are determined for both the upstream and the downstream regions. In order to illustrate the effects of velocity profile, the results for the slug flow and the parabolic velocity profiles are plotted simultaneously. The heat transfer characteristics of the flow are found to be rather sensitive to the Péclét number, the external Biot numbers and the velocity profile in the thermal entrance region.  相似文献

Because high school dropouts are among the least advantaged members of American society, the educational system that has failed them has the social responsibility for remediating their educational and developmental needs. The community college is proposed as the institution most able to develop policies and programs that will enable these least advantaged members of American society to overcome the educational system that has failed them. This paper discusses the responsibility of providing a quality education to all individuals, examines the role the community college can play in meeting the educational and social needs of dropouts, and presents an innovative program at a community college that has been particularly effective in meeting the needs of dropouts.  相似文献

The aim of this study is to provide information on the purposes, structure and operation of the process of supervision in the Turkish educational system. In this paper, the historical development of supervision services in the Turkish educational system, as well as the purposes and principles of educational supervision in Turkey and the structure of supervision in the Turkish educational system are defined. Moreover, the organization of sub-systems of the Ministry of National Education and that of supervision at elementary schools, hiring supervisors, their training, duties and responsibilities as well as working principles are presented. In addition, a detailed analysis of the supervision of institutions and teachers by supervisors is included.  相似文献

Summary A new index for expressing degree of reading disability in children is presented. Called the Dyslexia Quotient (D. Q.), it has the advantages of being simple to calculate and of being expressed in round numbers. Standardization of this new index is presented. In addition, the use of the Dyslexia Quotient in 50 patients who completed intensive dyslexia therapy is presented. An age-improvement distribution diagram, using the D. Q. is given. The authors suggest that the Dyslexia Quotient offers a valuable universal means of indicating degree of reading disability at any grade or age level.  相似文献
