OBJECTIVE: For successful prosecution of child sexual abuse, children are often required to provide reports about individual, alleged incidents. Although verbally or mentally rehearsing memory of an incident can strengthen memories, children's report of individual incidents can also be contaminated when they experience other events related to the individual incidents (e.g., informal interviews, dreams of the incident) and/or when they have similar, repeated experiences of an incident, as in cases of multiple abuse. METHOD: Research is reviewed on the positive and negative effects of these related experiences on the length, accuracy, and structure of children's reports of a particular incident. RESULTS: Children's memories of a particular incident can be strengthened when exposed to information that does not contradict what they have experienced, thus promoting accurate recall and resistance to false, suggestive influences. When the encountered information differs from children's experiences of the target incident, however, children can become confused between their experiences-they may remember the content but not the source of their experiences. CONCLUSIONS: We discuss the implications of this research for interviewing children in sexual abuse investigations and provide a set of research-based recommendations for investigative interviewers.  相似文献

To determine if actual practice was consistent with commonly recommended research methods and procedures, this study examined 130 studies reported over a 5-year period in three volumes of the Journal of Research in Science Teaching (JRST). The results were consistent with similar previous analyses (Shaver & Norton, 1980a, 1980b; Wallen & Fraenkel, 1988a) and indicate that appropriate generalizations beyond the confines of the reported studies may be impossible for most (64%) of the JRST studies surveyed. The findings also show that replication studies, which could be employed to offset deficiencies in generalizability, were not commonly encountered (3%) in these 130 reports. In addition, the study results indicate that many researchers (48%) do not properly restrict their conclusions based on the limits imposed by the accessible populations and samples used; nor do they typically provide possible alternative explanations for the outcomes obtained (76%). These findings prompt the following recommendations: 1. A greater awareness and use of replication as a check on generalizability should be encouraged by the science education community. 2. Clearly defined populations (target and accessible) and fully described samples warrant increased attention as report components from authors, reviewers, and editorial board members of JRST. 3. In light of the difficulties inherent in effecting random selection in educational settings, a greater emphasis should be placed on recognizing the limits that the underlying assumptions of inferential statistics place on research conclusions. The results of this study indicate that the methodological quality of published science education research should remain a concern for both practitioners and readers.  相似文献

A modification of the nonlinear curve-fitting procedure proposed by Wetherington and Lucas (1980) was used to assess how well Herrnstein’s (1970) equation for the rates of responding during concurrent schedules described performance. The equation fitted some results very well, accounting for 80% or more of the variance in the data in studies that used moderate-duration changeover delays and provided the same positive reinforcers, operanda, and simple schedules in the two components. The equation fitted the data poorly in other studies. The k parameter changed with several variables; it was not as constant as Herrnstein (1974) suggested. R0 did not fit Herrnstein’s interpretation as reinforcement from unprogrammed sources. Forty percent of all values of R0 were negative, and another 23% were unreasonably large (greater than 50 reinforcers/h). The data suggest that Herrnstein’s equation is not a general theory of concurrent-schedule responding, and that Herrnstein’s interpretation of k and R0 should be modified.  相似文献

We develop a single‐class period learning game for the Plan‐Do‐Study‐Act (PDSA) improvement cycle. The experiential activity walks teams through the PDSA problem‐solving process as they create paper American footballs and improve their performance using each step of the cycle. The game is one of the first to focus on PDSA. Key benefits include increased student attention, engagement, and learning. Empirical tests show that participant pre‐ and post‐test scores regarding their understanding of each phase of PDSA improved 21.2% after completing the game. Additionally, the treatment group performed 16.6% higher than the control group. In participant perception questions, 85% of participants felt the game was more effective than lecture or reading, 93% felt the game was fun, 95% felt the game improved their understanding of PDSA, and 98% felt the game was engaging.  相似文献

Anonymous questionnaires assessing the amount and nature of bullying/victimization were given to 1379 primary and middle school pupils (8–11; 11–14yrs) in two towns of Central and Southern Italy, Florence and Cosenza. The questionnaire closely followed the design of Olweus (1991) and Whitney and Smith (1993). Results were analysed in terms of percentages of bullying others and being bullied, types of bullying behaviour, where it occurred and who were the perpretators. Bullying was reported in both Italian areas at a more substantial level than found in other countries, including Norway, England, Spain and Japan, although it presented similar structural features to those reported elsewhere: being bullied decreased in older pupils, bullying others was most likely to be admitted by boys, the perpetretators were in the same class as the victims. Considering direct and indirect forms of bullying, year and gender differences are discussed for the two Italian areas and in cross-national perspective.  相似文献

While qualified school librarians can have a positive influence on children's literacy attainment, very little consideration is given to the educative role of librarians in schools. Lack of attention on these librarians' educative capacity may be due to a devaluing of the educational contribution of school librarians, and it can be argued that school libraries are poorly valued in current times, as evidenced in cuts to budgets and staffing. While school librarians may foster literacy and literature learning through a range of strategies, and for diverse purposes, perhaps their most expected contribution relates to the fostering of literacy and literature learning through wide reading and reading engagement in students. However, little is known about the specific barriers that librarians in schools may encounter in achieving these goals in the current school environment. Research from teacher librarians at 30 Australian schools is drawn upon to explore barriers to children's literacy and literature learning in school libraries. Recurring barriers were limited time and competing demands, crowded curriculum, low teacher valuing, low student engagement, skills and motivation, issues with parental support, limited space and constrained budget. These findings provide a valuable foundation for future inquiry in this under‐researched space.  相似文献

This study examines the impact that secondary school studies have on university accounting courses. Multiple regression analysis has been used to determine the significance of various academic factors. Secondary school accounting and mathematics were found to have far greater effectiveness in predicting results in the initial university accounting course than did other variables, but this benefit diminished in the second year and vanished in the third year of the accounting programme.  相似文献
