Invariance of Item Characteristic Functions With Variations in Instructional Coverage   总被引：1，自引：0，他引：1  

M. David Miller  Robert L. Linn 《Journal of Educational Measurement》1988,25(3):205-219

An assumption of item response theory is that a person's score is a function of the item response parameters and the person's ability. In this paper, the effect of variations in instructional coverage on item characteristic functions is examined. Using data from the Second International Mathematics Study (1985), curriculum clusters were formed based on teachers' ratings of their students' opportunities to learn the items on a test. After forming curriculum clusters, item response curves were compared using signed and unsigned sum of squared differences. Some of the differences in the item response curves between curriculum clusters were found to be large, but better performance was not necessarily related to greater opportunity to learn. The item response curve differences were much larger than differences reported in prior studies based on comparisons of black and white students. Implications of the findings for applications of item response theory to educational achievement test data are discussed  相似文献   

Measuring the severity of child maltreatment     

Litrownik AJ  Lau A  English DJ  Briggs E  Newton RR  Romney S  Dubowitz H 《Child abuse & neglect》2005,29(5):553-573

OBJECTIVE: The purpose was to identify different operational definitions of maltreatment severity, and then to examine their predictive validity. METHOD: Children and their primary caregivers participating in a consortium of ongoing longitudinal studies were interviewed when they were approximately 4 and 8 years of age to assess behavior problems, and developmental and psychological functioning. Four different severity definitions were identified and applied to 519 children who were reported for alleged maltreatment between Birth and the Age 8 interview. A taxonomy for defining maltreatment characteristics (Barnett, Manly, & Cicchetti, 1993) was applied to Child Protective Service records to define severity as (a) Maximum Severity within each of five maltreatment types, (b) Overall Maximum Severity across the five types, (c) Total Severity or the sum of the maximum severity for each of five types, and (d) Mean Severity or the average severity for those types of maltreatment alleged, during each of two time periods-Birth to Age 4, and Age 4 to Age 8. RESULTS: Regression analyses that controlled for socio-demographic factors, early maltreatment (Birth to Age 4), prior functioning (Age 4), and site revealed that (a) all four severity definitions for maltreatment reports between Age 4 and Age 8 predicted Age 8 behavior problems, (b) Maximum Severity by Type and Mean Severity predicted adaptive functioning at Age 8, and (c) only Maximum Severity by Type was related to anger, at Age 8. Follow-up regression analyses indicated that only Maximum Severity by Type, specifically physical abuse, accounted for outcomes, beyond maltreatment occurrence versus non-occurrence. CONCLUSION: The results suggest that maltreatment severity definitions that preserve ratings within types of maltreatment may be the optimal approach to measure the severity of children's experiences.  相似文献   

Beliefs about Children: A Comparative Study of Mothers, Teachers, Peers, and Self   总被引：1，自引：0，他引：1  

Scott A. Miller  Teresa L. Davis 《Child development》1992,63(5):1251-1265

This study was designed to clarify findings from the parents' beliefs literature concerning the nature and the effects of parental accuracy. Subjects were 60 second- and fifth-grade children (mean ages = 8–5 and 11–5, respectively), their mothers, and teachers. Each child responded to 4 cognitive tasks, predicted how he or she would perform on each task, made self-assessments of preferences and personality traits, and predicted the response of 2 peers to all of the measures. Both the child's mother and the child's teacher were shown the tasks and made similar predictions of the child's probable response. As in previous studies, mothers were above chance but far from perfect in predicting their children's cognitive performance and preferences and traits. Teachers were as accurate as mothers in judging cognitive abilities; they were less successful, however, on the preference and personality items. The children's predictions, whether for self or peers, were less accurate than those of the adults on all tasks. The accuracy of the mothers' predictions correlated positively with external measures of the child's cognitive performance. This finding is compatible with the Hunt "match hypothesis," although other bases for the correlations also exist.  相似文献   

Conceptions and Expectations of Mentoring Relationships in a Teacher Education Reform Context     

Semiyu Aderibigbe  Laura Colucci-Gray  Donald S. Gray 《Mentoring & Tutoring: Partnership in Learning》2016,24(1):8-29

Researchers indicate that prior experience and beliefs about learning and teaching held by practicing and pre-service teachers contribute significantly in shaping their mentoring relationships and, more broadly, their career outlook and aspirations. While mentoring is commonly seen as a form of support for pre-service teachers, mentoring can be pivotal in the creation of enabling environments in which collaborative, professional dialogs are undertaken. Yet, there lies a tension between enculturation into the norms of schools and promoting self-belief, participation, and collaboration. Drawing on a qualitative methodology, in this study we focused on the conceptions and expectations of classroom mentoring within the context of a teacher reform initiative in Scotland. Findings indicated that participants in the study held a mixture of beliefs regarding mentoring practices. Implications for partnership arrangements in initial teacher education and teachers’ career development were discussed.  相似文献   

Race and Racelessness in CMO Marketing: Exploring Charter Management Organizations’ Racial Construction and its Implications     

Laura E. Hernández 《Peabody Journal of Education》2016,91(1):47-63

As schools face growing competitive pressures, researchers have investigated the increasing reliance on marketing and its implications for various racial and socioeconomic groups. Although research has expanded our knowledge of marketing's gatekeeping qualities, it has less often considered the manner in which school marketing efforts contribute to broader, social understandings of race and the characterization of racial groups. Because marketing has historically played a pivotal role in the construction of race and racial identity in American society, this exploratory study considers if and how racial identities are configured in the marketing materials of two prominent charter management organizations (CMOs). Employing critical discourse analysis, this study suggests that the focal CMOs employ a racial discourse characterized by indirect racial references that are supplemented with negative depictions of the communities and racial groups they serve. I argue that the focal CMOs’ racial discourse contributes to the reification of colorblindness, the dominant racial frame that characterizes the manner in which many understand race and race relations. This paper concludes with a discussion of the implications of the CMOs’ espousal of color blindness in their marketing materials, noting how the discursive obfuscation of race affects the manner in which educational leaders imagine educational solutions and neglects the continued and unique impact that race has in everyday lives.  相似文献   

Student variables in the evaluation of mediated learning environments     

Laura Helena Porras‐Hernandez 《Distance Education》2000,21(2):385-405

This paper discusses the results of the student dimension in an evaluation applied to an educational teleconferencing system in a Mexican higher education institution. Traditionally, this institution has gained prestige for its face‐to‐face programs, and students are not used to mediated or distance learning. Courses offered through this system are based on a pedagogical model which emphasises the active role of the learner. Therefore, student variables such as perceptions of the self, and self‐regulatory processes become key components in this learning environment. Conclusions here presented correspond to: (i) students’ expectations; (ii) perceptions of efficacy for self‐regulated learning, and perceptions of the course, and of the teacher's and learner's work.

Results indicate students’ expectations focus on ‘learning more than in face‐to‐face situations’, followed by ‘using technology’, and ‘having freedom and initiative’. Perceptions of efficacy for self‐regulated learning were high overall. Nevertheless, analyses of individual items indicate specific areas requiring improvement. Qualitative data on perceptions of the course, and teachers’ and learners’ work suggest that these courses are more demanding than the face‐to‐face ones they are taking. Students’ responses include attitudinal and cognitive adjustments needed for these learning environments. These results have led to improvements, which are presently being applied. The importance of considering these student variables in evaluations of mediated learning environments is discussed.  相似文献   

Executive Function Skills,Early Mathematics,and Vocabulary in Head Start Preschool Children     

Hattie A. Harvey  Gloria E. Miller 《Early education and development》2017,28(3):290-307

Research Findings: The contribution of 3 executive function skills (shifting, inhibitory control, and working memory) and their relation to early mathematical skills was investigated with preschoolers attending 6 Head Start centers. Ninety-two children ranging in age from 3 years, 1 month, to 4 years, 11 months, who were native English or Spanish speakers were assessed for these executive function skills as well as their receptive vocabulary skills and early mathematical abilities using the Child Math Assessment (Starkey, Klein, & Wakeley, 2004), which captures an array of skills across 4 domains. Hierarchal regression analyses revealed that inhibitory control and working memory made unique contributions to children’s early mathematical abilities in the domains of numeracy, arithmetic, spatial/geometric reasoning, and patterning/logical relations after we controlled for age, receptive vocabulary, and previous Head Start experience. Furthermore, receptive vocabulary also accounted for significant variance in children’s early mathematical abilities above and beyond executive function skills. No group differences emerged between English-only and dual language learners on the fit of the regression models. Practice or Policy: These findings extend previous research highlighting the interface of executive function skills and mathematical learning in early childhood with further evidence to support this relationship beyond early numeracy and counting using a broad measure of critical early math skills. In addition, the intricate role of language in the development of early mathematical competence is considered. Implications of these findings for scaffolding executive function skills and vocabulary within prekindergarten math curricula are discussed, with particular consideration for children from low socioeconomic backgrounds.  相似文献   

Implementation of the PATHS Curriculum in an Urban Elementary School     

Ronald Seifer  Kathleen Gouley  Alison L. Miller  Audrey Zakriski 《Early education and development》2004,15(4):471-486

We examined the effectiveness of the PATHS curriculum in a magnet elementary school serving a distressed urban area. Aspects of social-emotional competence were examined for second graders who had, and had not, received the PATHS intervention. The intervention groups differed, with the control group having lower social-emotional competence than the intervention group. The measures that contributed most to this effect were objective ratings of observed social competence, and self-reports of child depression and social rejection. School personnel reported modest enthusiasm and approval of the PATHS curriculum. The importance of school acceptance, and contexts that may enhance such acceptance, are discussed.  相似文献   

Latent inhibition of the conditioning context: Further evidence of contextual potentiation of retrieval in the absence of appreciable context-US associations     

Mary Ann Balaz  Sharon Capra  Wesley J. Kasprow  Ralph R. Miller 《Learning & behavior》1982,10(2):242-248

Previous research in our laboratory has found superior performance when classically conditioned responses are observed in the training context as opposed to outside it, even when direct context-US associations have been minimized by either the choice of conditioning parameters or extinction to the context. The present experiment used latent inhibition of the conditioning context as an alternative method of examining contextual cue effects in the absence of appreciable direct context-US associations. Water-deprived rats received tone-footshock pairings in one of two distinctly different apparatuses, but all were tested in a common apparatus. Animals conditioned in the test enclosure displayed more lick suppression than those conditioned outside the test enclosure. Other animals tested without the tone present also exhibited more suppression if conditioning had occurred in the test context rather than outside it, indicating that direct associations between the conditioning context and shock had been formed. However, when formation of direct associations to the conditioning context was attenuated in additional animals through extensive preexposure to the context prior to conditioning, more suppression to the tone was still seen when conditioning had occurred in the test context rather than outside it. These results add support to the position that the training context augments recall even when direct associations between the context and the US are attenuated. The phenomenon is discussed in terms of facilitated retrieval of nominal CS-US associations, configural retrieval cues, and conditional discriminations.  相似文献
