This study examined the reliability of the Mantel-Haenszel indexes across different samples of test takers as well as across sample sizes and investigated whether these indexes are robust to item context effects. Mathematics data from the Second International Mathematics Study (SIMS; 1985) for U.S. eighth-grade students were analyzed. The results suggest that the MH D-DIF is robust to item context effects. However, larger sample sizes than those used in this investigation (N = 141-167 for the focal group) may be necessary to obtain stable estimates from the Mantel-Haenszel procedure. 相似文献

The dramatic growth in the number of children learning English as a second language in our country has led to a corresponding
increase in the need to understand how teachers and schools can effectively teach children who are learning English as a second
language. Many teachers report not feeling prepared to meet the needs of these children (National Center for Education Statistics,
Teacher preparation and professional development: 2000. , 2002). The current study used focus group interviews to examine how Head Start teachers in one program addressed the special learning
needs of children learning English in their classrooms. Key challenges involved communicating with children and their families
in their home language. Teachers used other staff, parents, and children in the classroom to interpret. Strategies involved
visual aids, pictures, gestures, and a welcoming classroom environment. Resources used by teachers were professional development
and language skills of other staff. However, available resources were often underutilized and limited for teachers to use
in meeting the challenges the teachers faced in the classroom. Suggestions are presented for overcoming the challenges and
limited resources encountered by teachers, such as changes in preservice and inservice training opportunities, and second
language learning opportunities for teachers. Further implications for training and research are discussed. 相似文献

Age and sex differences in beliefs about strategies for reducing parental anger were assessed. The central question was whether direct intervention strategies are the most effective for, and reflect more advanced understanding of, anger reduction. In Study 1, 120 children ages 4-9 years generated strategies they believed would lessen a parent's anger elicited by 3 situations of increasing complexity. Across ages children proposed direct intervention strategies for the simplest situation, and there was an age increase in suggesting direct intervention strategies for the more complex situations. In Study 2, 180 children, ages 4-12 years, and their parents rated the effectiveness of the strategies generated for the most complex situation (interparental argument). There was no longer a unilinear age increase in believing direct intervention strategies effective. Unlike with older and younger children, there was no agreement between 7-9-year-olds and their parents on the efficacy of direct intervention strategies. 相似文献

Children's emotionality--fear, anger, and joy--observed outside of the relationship with the mother (in standard laboratory paradigms), and within that relationship (in mother-child interactions), and mothers' responsiveness, all at 9 and 14 months, were examined as predictors of the reunion behaviors in the Strange Situation at 14 months in 112 children. Many predictors were linked to the reunion behaviors, but most of those relations were at least partially mediated by children's separation distress, which itself strongly predicted the reunion behaviors. Those relations were no longer significant when distress was controlled. Several links, however, remained significant, and they were unmediated by distress: Almost all involved measures assessed within the context of the mother-child relationship. In particular, possible markers of a suboptimal relationship (children's dampened joy and increased anger in interactions with the mother, poor maternal responsiveness) were associated with more avoidance and resistance upon reunion, even after accounting for the strong impact of distress. Studying how factors measured outside of and within early relationships influence the components of the attachment system may foster understanding of child behavior in the Strange Situation. 相似文献

The practice of sexting is becoming increasingly common among college students but has the potential to both initiate productive interactions with others and interfere with relationship development. The purpose of this paper is to report on the findings of a study on sexting among college students and to provide a framework through which practitioners working with this population would be able to effectively intervene. Implications for clinical practice include more specific assessment questions for practitioners, focus on better managing riskier behavior, and guidance toward using technology in relationally responsible and supportive ways. 相似文献

The function of accurately monitoring one’s own learning is to support effective control of study that enhances learning. Although this link between monitoring accuracy and learning is intuitively plausible and is assumed by general theories of self-regulated learning, it has not received a great deal of empirical scrutiny and no study to date has examined the link between monitoring accuracy and longer-term retention. Across two studies, college students paced their study of key-term definitions (e.g., “Proactive interference: Information already stored in memory interferes with the learning of new information”). After all definitions were studied, participants completed practice cued recall tests (e.g., “What is proactive interference?”) in which they attempted to type the correct definition for each term. After each test trial, participants judged how much of their response was correct. These study-test-judgment trials continued until a definition was judged as correct three times. A final cued recall test occurred two days later. In Study 1, judgment accuracy was manipulated experimentally, and in Study 2, individual differences in accuracy were examined. In both studies, greater accuracy was associated with higher levels of retention, and this link could not be explained by differential feedback, effort during study, or trials to criterion. Results indicate that many students could benefit from interventions aimed at improving their skill at judging their learning. 相似文献

I Forget What That's Called! Children's Online Processing of Disfluencies Depends on Speaker Knowledge 下载免费PDF全文
Speech disfluencies can convey information to listeners: Adults and children predict that filled pauses (e.g., uhh) will be followed by referents that are difficult to describe or are new to the discourse. In adults, this is driven partly by an understanding that disfluencies reflect processing difficulties. This experiment examined whether 3½‐year‐olds' use of disfluencies similarly involves inferences about processing difficulty. Forty children were introduced to either a knowledgeable or a forgetful speaker, who then produced fluent and disfluent utterances. Children exposed to the knowledgeable speaker looked preferentially at novel, discourse‐new objects during disfluent utterances. However, children who heard the forgetful speaker did not. These results suggest that, like adults, children modify their expectations about the informativeness of disfluencies on a speaker‐specific basis. 相似文献

Developmental Differences in Relations Between Episodic Memory and Hippocampal Subregion Volume During Early Childhood 下载免费PDF全文

Episodic memory shows striking improvement during early childhood. However, neural contributions to these behavioral changes are not well understood. This study examined associations between episodic memory and volume of subregions (head, body, and tail) of the hippocampus—a structure known to support episodic memory in school‐aged children and adults—during early childhood (n = 45). Results revealed significant positive relations between episodic memory and volume of the hippocampal head in both the left and right hemispheres for 6‐ but not 4‐year‐old children, suggesting brain–behavior relations vary across development. These findings add new information regarding neural mechanisms of change in memory development during early childhood and suggest that developmental differences in hippocampal subregions may contribute to age‐related differences in episodic memory ability. 相似文献
