A multifaceted, relationally focused intervention involving group and individual pre- and postnatal counseling, print resources, and community resources encouraged 390 fathers of newborn infants in Vietnam to responsively support mothers and work with them as a parenting team. Both partners completed questionnaires prebirth and 1-, 4-, and 9-months postbirth on measures of breastfeeding support, exclusive breastfeeding duration, relationship quality, and infant development. Compared to 412 comparison group couples, intervention couples evidenced greater father support, especially in terms of helping and responsiveness to the mother's needs. This support predicted longer exclusive breastfeeding duration, improved relationship quality, and higher levels of infant development at 9 months. Sensitively working together with mothers as a coordinated team enhanced couple's relationship functioning and improved children's developmental outcomes.  相似文献

This article compares traditional college students' perceptions of effective teaching behaviors with nontraditional students' perceptions. A 15-item questionnaire was completed by undergraduates at a small Southeastern university. Nontraditional students viewed personality and interaction behaviors as more indicative of effective teaching, whereas traditional students focused on behaviors that potentially would enhance grades. The implications of the findings are discussed in light of techniques and approaches that facilitate the needs of both types of students.His major areas of interest include testing and counseling. Nina Mattie, M.A. is a recent graduate of the University of West Florida in the area of school psychology. Stephen J. Vodanovich, Ph.D. is an assistant professor in the psychology department at the University of West Florida. His major areas of interest are social psychology and industrial/organizational psychology. Chris Piotrowski, M.A. is a consultant in forensic psychology. His major areas of interest are personality assessment and online database searching.  相似文献

Based on the success reported by the behaviorally oriented programmed instruction movement in the 1960s, the Navy in the late 1960s and early 1970s began to individualize and self-pace a number of their high student throughput apprentice training courses. To facilitate self-pacing the Navy set up a centralized computer-managed instruction (CMI) system to manage self-paced courses. This paper describes the evolution of that CMI system, reviews a number of studies done on the system over 10 years (many of which were published as internal technical reports with restricted distribution), describes the demise of the system, and discusses future directions of self-paced and individualized instruction.  相似文献

Two different bond-graph schemes for the modeling of circulating fluids are discussed and compared. The first uses a heuristic approach wherein the flow path is broken into segments. Each segment has separate hydraulic and thermal submodels which are linked with active bonds. The model is general enough to handle natural convective flows, heat storage, conduction, forced convective heat transfer and heat energy sources. The second method, applicable to pumped flows, uses a modal analysis approach to derive state equations for the modal temperatures, the time varying coefficients of the spatially varying mode shapes in a separation of variables solution for the temperature partial differential equation. Two examples are worked to illustrate the models. Numerical simulation results are presented using the first method and a simple analytic solution given to illustrate the second.  相似文献

Mastery learning, it is claimed, is among the most successful practices in higher education. Evidence supporting this claim has recently been criticized as empirically weak. This experiment employed a four-group, pre-post design to examine the learning consequences of a computer-administered mastery-testing approach in comparison with a seminar-discussion approach in a third-year university course. The mastery-testing approach generated significantly higher learning achievement than did the seminar-discussion approach. Replication and extension of this research approach are recommended to support generalizations across mastery-testing techniques, delivery systems, and disciplines.  相似文献

As part of a longitudinal twin study of literacy and language, we conducted a behaviour‐genetic analysis of orthographic learning, spelling and decoding in Grade 2 children (225 identical and 214 fraternal twin pairs) in the United States and Australia. Each variable showed significant genetic and unique environment influences. Multivariate analyses revealed very high genetic correlations among the variables, indicating that the same genes are involved in their aetiology. These genes are partly independent of those contributing to intelligence. A further analysis indicated that the covariation between decoding and orthographic learning is mediated by shared genes rather than by a direct causal path. The authors argue that a learning parameter, most directly assessed by orthographic learning in this study, underlies all three literacy variables. The results are also discussed in relation to Share's self‐teaching hypothesis, which may require modification.  相似文献

This paper examines the experiences and understandings of primary (K6) school pupils with regards to managing issues of risk and safety during their everyday use of information and communication technologies (ICTs). The paper is based on survey and interview data with pupils aged 7 to 11 years old in five English primary schools (n = 612). Analysis of these data shows that whilst most pupils recognised a general need to be mindful of ICT-related risks and dangers, their actual experiences of risk tended to be described in terms of operational problems encountered when using ICTs. Conversely, pupils’ understandings of potential risk were often based upon exaggerated fears deriving from a number of moral panics relating to child safety. These data suggest that official notions of ‘e-safety’ remain abstract and poorly understood concepts for many children. In considering what implications these data have for the ongoing ‘e-safety’ agenda in UK schools the paper concludes by suggesting three possible areas of change: (1) re-orientating the topic and tone of the official discourses surrounding e-safety; (2) increasing pedagogical interventions in primary schools aiming at enhancing pupils’ critical literacy skills; and (3) establishing a meaningful and sustained dialogue between pupils, teachers and parents about safety and risk when using ICTs.  相似文献
