An important goal of education in developing countries is to implement and improve early childhood education. A pre–post intervention–control design was used to compare a piloted-revised versus a regular preschool program offered by an organization in rural Bangladesh. After 7 months in operation, the quality of the piloted-revised program was higher than the regular program, though the regular program had also improved. Children attending pilot preschools made greater gains than children attending regular preschools on most outcome measures. Action research was conducted alongside the quantitative evaluation to study the process of the implementation and to identify areas for further improvement. 相似文献

The relationships between heuristic literacy development and mathematical achievements of middle school students were explored
during a 5-month classroom experiment in two 8th grade classes (N = 37). By heuristic literacy we refer to an individual’s capacity to use heuristic vocabulary in problem-solving discourse
and to approach scholastic mathematical problems by using a variety of heuristics. During the experiment the heuristic constituent
of curriculum-determined topics in algebra and geometry was gradually revealed and promoted by means of incorporating heuristic
vocabulary in classroom discourse and seizing opportunities to use the same heuristics in different mathematical contexts.
Students’ heuristic literacy development was indicated by means of individual thinking-aloud interviews and their mathematical
achievements – by means of the Scholastic Aptitude Test. We found that heuristic literacy development and changes in mathematical
achievements are correlated yet distributed unequally among the students. In particular, the same students, who progressed
with respect to SAT scores, progressed also with respect to their heuristic literacy. Those students, who were weaker with
respect to SAT scores at the beginning of the intervention, demonstrated more significant progress regarding both measures. 相似文献

Young women in their teen years and women who have had previous cesarean births are two special groups taught by Lamaze Certified Childbirth Educators. This review includes research related to both groups. Information collected from these studies can help childbirth educators assess their programs and plan appropriate classes that address the particular needs of each group. 相似文献

The paper draws upon a national study to analyze two issues relevant to the future effectiveness of the American agricultural technology system: (1) linkages between research and technology transfer activities; and (2) relationships between the public and private sectors. Increased commitments to basic research by the US Department of Agriculture and the state agricultural experiment stations have served to exacerbate existing strains between research and technology transfer functions and units. Both the feasibility and desirability of having USDA's Agricultural Research Service simultaneously seek to strengthen its basic research capabilities and its commitment to technology transfer have been questioned. Within the landgrant universities, multiple pressures have served to attenuate traditional ties among agricultural researchers, extension specialists, and county extension agents.Private sector activity in agricultural research and the provision of technical information has increased following the expansion in the domains of knowledge over which firms can establish property rights and the concentration of production in a smaller number of economic units. Adjustments in the activities of the public sector in response to these changes can be seen. Still, the optimal mix of public-private sector activities in both research and technology transfer has yet to be fully analyzed. Current analyses (and public policy) are excessively constrained by the “property rights” approach to technological change. 相似文献

Bellman's dynamic programming equation for the optimal index and control law for stochastic control problems is a parabolic or elliptic partial differential equation frequently defined in an unbounded domain. Existing methods of solution require bounded domain approximations, the application of singular perturbation techniques or Monte Carlo simulation procedures.In this paper, using the fact that Poisson impulse noise tends to a Gaussian process under certain limiting conditions, a method which achieves an arbitrarily good approximate solution to the stochastic control problem is given. The method uses the two iterative techniques of successive approximation and quasi-linearization and is inherently more efficient than existing methods of solution. 相似文献

The separation of student and instructor is the core characteristic of distance education (Simonson et al., 2012, p. 28), contributing to one of the biggest challenges to distance education—attrition (Dueber & Misanchuk, 2001, p. 2). By the very nature of distance education, students are different locations from one another and their instructor. The instructor’s challenge is figuring out how to make students feel connected and able to succeed in this new learning environment. The development of a sense of community is an effective and efficient way to help ensure the success of the distance education program and can directly address the challenge of distance education attrition. By developing a sense of community, an instructor can create an environment that is conducive to student success. This importance was demonstrated when the University of North Carolina at Chapel Hill Department of Romance Languages and Literatures (ROML) transitioned their introductory Spanish course to a hybrid model. 相似文献

Drawing session from an art and anatomy workshop for medical students at the University of Texas Health Science Center at San Antonio and art students at the University of Texas at San Antonio. A current trend in medical education is to integrate aspects of the humanities into the medical school curriculum. In this issue of ASE, Dr. Charleen Moore and her colleagues describe an art and anatomy workshop that uses drawing exercises to increase observational skills, to foster the development of humanistic sensitivities, and to emphasize the emotional aspects of dealing with mortality.

The educational challenges girls face are often explained by economics. However, gender norms and identities, constructed historically but subject to change, also play a crucial role. In Kenya, little attention has been paid to the negative social constructions that keep girls from attaining the education they want. This article analyses the role of social construction among girls who are in and out of two secondary schools in Nairobi province, Kenya. Data were obtained from interviews with adolescent girls attending the schools, female dropouts previously affiliated with those two schools, and teachers at the schools. All the challenges that girls faced in attempting to secure secondary education were linked to social construction; they were deeply rooted in gender roles as defined by the cultural context and reinforced by socialisation. Based on the results, the authors hold that women must lead community efforts toward changes that will enhance their daughters’ educational opportunities. 相似文献
