South Carolina recently implemented a new initiative to improve the quality of pre-kindergarten and kindergarten classrooms in primary schools. This article describes the initiative and examines evidence that such an effort can have a positive effect on early childhood program quality. Data from both classroom observations using the ECERS-R scale, and from teacher surveys, are used to examine the effectiveness of the quality improvement effort. Results indicate that training and support coupled with accountability requirements can facilitate positive changes within classrooms. Examples of positive changes teachers report they made as the result of this process are included, along with changes in ECERS-R quality rating scores.  相似文献

In multinational corporations, new models of learning are developing. A particular model with direct applications for challenges facing distributed workforces is one that combines the strengths of formal and informal learning while focusing on participants’ work‐based tasks. An operationalisation of this model in the context of the ongoing professional development of the engineers, geologists, and other technical specialists in a multinational oil company (Shell EP) is described. Important for the quality control and continual improvement of the implementation of the model is a set of criteria for the design and evaluation of courses reflecting its work‐based learning approach. Merrill's First Principles of Instruction (2002) form a starting point for such a model, but need to be expanded to reflect the particular needs of the Shell EP context. This article presents the expansion of Merrill's First Principles as the Merrill+design and evaluation criteria for courses with work‐based activities for technical professionals and demonstrates how the criteria can be applied through a selection of some results of evaluations of more than 60 of the Shell EP courses using a course‐scan methodology based on the Merrill+ criteria. Implications of use of the Merrill+ criteria for design and evaluation are discussed.  相似文献

During the forty years since C. P. Snow decried the existence of two cultures and castigated literary intellectuals for their lack of concern for humanity as a whole, an intellectual revolution in the humanities, driven in part by the intellectual obliteration of boundaries between disciplines and in part by globalization, has reoriented scholars toward engagement in the world and communication with scientists. A recognition that interdependence makes cooperation essential, whether among scholars or among nations, is bringing about an era of cooperation among disciplines and between academic and non-academic institutions.  相似文献

Early intervention is critical for improved prognosis and quality of life for young children with developmental delays and disabilities. Yet, disparities persist among underserved families with young children. These disparities include knowledge of child development, use of medical providers as referral sources, and later diagnosis. The current study employed a mixed method, randomized controlled trial to examine participant outcomes among low-income, underserved families who received child development information. The information included the 42-page Milestone Moments booklet that was developed by the Centers for Disease Control and Prevention’s Learn the Signs/Act Early initiative. Participants (n = 108) included parents or legal guardians of children ages birth through 5 years. The participants were predominantly Black/African American (86 %) and female (90 %), and all had incomes below the federal poverty level. Study variables related to the location (home vs. child care center) and context (single session vs. extended visits) for delivering the information did not yield significant differences. Yet, there were clear findings that parents who received the booklet reported increased knowledge about child development, a decrease in concern about their own children’s developmental progress, and a positive perception of the booklet. On interview, parents reported learning new information about child development or being reminded of developmental information they had forgotten and the importance of following up with professionals when concerns arose. While not statistically significant, there was a consistent trend toward greater participant outcomes for parents who received materials in the child care setting relative to the home.  相似文献

Black, Betty, and Logan, Arliss. Links between Communication Patterns in Mother-Child, Father-Child, and Child-Peer Interactions and Children's Social Status . Child Development, 1995, 66 , 255–271. In this study, we examined communication in the family and peer systems in relation to children's sociometric status. Codes measured turn-taking skills and utterance types for 43 children (ages 24–60 months) with mothers, fathers, and peers. Communication differences in the family and peer systems were strongest for popular versus rejected status children and their parents, but differences were also found for controversial and neglected status children and their parents. Rejected status children demonstrated turn-taking styles that included irrelevant turns, interruptions, simultaneous talking, and noncontingent responding. Parents of rejected children used higher proportions of requests than parents of popular children but failed to allow their children time to respond to the requests. Popular status children were more likely to alternate turns, provide explanations to peers, and participate in episodes of cohesive discourse. Interaction patterns were examined for potential mechanisms of transfer between family and peer systems.  相似文献

The domain of Tele-Learning may be a new one, but it has many roots. In essence, it can be defined as telematics applied for learning-related purposes. Examples of tele-learning may be defined by category relating to purpose. Thus five purposes of using 'Teleware' may be the publication and dissemination of information, such as through Web sites; structured communications through e-mail; collaboration through groupware; information and resource handling through search engines; and specific applications for course delivery and support. An alternative perspective relates to aspects of the user-interface and human- computer interactions, ranging from the software engineering world, to the importance of a cognitive and social fit in terms of potential usability and dissemination. In practice however, evaluating teleware to ensure tele-learning may take place requires an appropriate model. This paper outlines the 3-G model, which hypothesises that an individual's likelihood of using a telematics application in teaching or learning can be expressed as a vector sum of three vectors–'gewin' or perceived pay-off, 'gemak' or level of difficulty or discomfort in making use of the application, and 'genot' or subjective personal interest in and response to the application. This model has the potential to provide a helpful interpretative framework in a number of investigations into the complex relationship between telematics materials and facilities, and the learning they may generate. It can also be used to assess the potential of new developments, such as Cyberlibraries, lesson-support environments, and course- support environments, that are emerging. © 1999 IFIP, published by Kluwer Academic Publishers  相似文献
