We tested whether urban middle-school students from mostly low-income homes had improved academic vocabulary when they participated in a freely available vocabulary program, Word Generation (WG). To understand how this program may support students at risk for long-term reading difficulty, we examined treatment interactions with baseline achievement on a state standardized test and also differential effects for students with (n = 398) and without (n = 1,395) individualized education plans (IEPs). Students in this unmatched quasi-experiment (5 WG and 4 comparison schools) completed pre- and postvocabulary assessments during the intervention year. We also retested student vocabulary knowledge after summer vacation and the following spring on 11 target words to construct a longitudinally consistent scaled score across 4 waves of data. Growth models show that students experienced summer setback. Although there were no average underlying differences in growth or differences in summer setback for students by baseline achievement, better readers improved more from program participation. IEP status did not predict differential benefits of program participation, and students with IEPs maintained gains associated with participation in WG; however, participation in the program did not change underlying growth trajectories favoring students who did not have IEPs. 相似文献

Scientific literacy is essential to survive in this technological world, but it appears that scientific literacy is not of high priority for many students. This research project was undertaken to gather demographic data, intentions to engage in science, and attitudes of urban, middle school students. Scores on the Simpson-Troost Attitude Instrument were analyzed using the Statistical Analysis System. Results indicate less than 50% of the students come from high-school-graduated parents who work full-time to support the family. Less than 50% of these students indicate any interest to engage in science at the high school level, yet many plan to enter a science-related career. A majority of the students possess an uncertain attitude toward their science teachers and science curricula. However, all possessed high achievement motivations, strong positive attitudes toward their families, and high self-concepts. 相似文献

This case study extends previous research on the theory and practice of performance analysis by examining the application of one model, the Performance Analysis for Training (PAT) Model, in an organization that was implementing ISO‐9000 processes. The research questions focused on whether using the PAT Model produced the expected results and on the correspondence between the actual process used for the performance analysis and the process outlined in the PAT Model. The study findings revealed that the performance analysis produced the expected results and that the results were influenced by the three elements identified in the model's conceptual framework—organization characteristics, decision maker characteristics, and analyst characteristics—and their interactions. In addition, four adaptations to the PAT model were identified. 相似文献

Methodological considerations for studying science-in-the-making in educational settings 总被引:3,自引:0,他引:3
In this paper we explore the methodological implications of sociocultural approaches for the study of scientific knowledge
and practices. Research in science studies and science education is reviewed with a focus on methodological considerations.
Informed by empirically-based studies of scientific practices from multiple disciplinary perspectives, we describe our perspective
for investigating science education which combines ethnography and discourse analysis. This theoretical position on the discursive
nature of the social construction of school science-in-the-making forms the basis for theoretical and methodological critique
and discussion. We provide a review of the history of nature of science (NOS) research to trace the methodological influence
of Science and Technology Studies in science education. Four methodological issues associated with studying science as cultural
practices are discussed: the local and contingent nature of situated definitions of science; theory dependence and coherence
of research methodologies; attention to the study of school science-in-the-making; and reflexivity. 相似文献

From an ethnographic case study of a state-funded residential school for the Deaf, the authors employed Critical Discourse Analysis to identify competing discourses in the talk of educators. These discourses are embedded in the historical oppression and labeling of deaf people as disabled and the development of Deaf culture as a counter-discourse. Implications include changing teacher/administrator hiring practices, improving professional development options, and distributing power between Deaf and hearing educators. 相似文献

This study investigated the relations of three aspects of morphological awareness to word recognition and spelling skills
of Dutch speaking children. Tasks of inflectional and derivational morphology and lexical compounding, as well as measures
of phonological awareness, vocabulary and mathematics were administered to 104 first graders (mean age 6 years, 11 months)
and 112 sixth graders (mean age 12 years, 1 month). For the first grade children, awareness of noun morphology uniquely contributed
to word reading, and none of the morphological tasks were uniquely associated with spelling. In grade 6, derivational morphology
contributed both to reading and spelling achievement, whereas awareness of verb inflection uniquely explained spelling only.
Lexical compounding did not uniquely contribute to literacy skills in either grade. These findings suggest that awareness
of both inflectional and derivational morphology may be independently useful for learning to read and spell Dutch. 相似文献

This article considers moral agendas projected onto parents that mobilise them to supplement school literacy education with private tutoring. The theoretical frame draws on the concepts of responsibilisation as emerging market-embedded morality, ‘nudge’ social policies, edu-business and hidden privatisation in education. This framing is applied to two empirical moments: firstly, debates around the Australian government’s ‘Tutorial Voucher Initiative’ of 2004; and secondly, tutoring advertisements and items in school newsletters collected in early 2016. In the first moment, parents were somewhat reluctant to take up free supplementary tutoring; in the second, private literacy tutoring is increasingly normalised and legitimated as parents are nudged to supplement the work of the school. 相似文献

Research Findings: Across 63 Hong Kong families, both Filipina domestic helpers and mothers separately rated their own caregiving style (warmth and control) and kindergarten children's social competence. Results indicated that Filipina helpers rated themselves as higher in warmth than mothers did. In addition, self-rated warmth of both caregivers, and Filipina domestic helpers' self-perceived control were correlated with children's social competence. With ratings of warmth and control from both Filipina helpers and mothers included in separate regression equations, mothers' warmth was a strong unique correlate of all measures of children's social competence. However, Filipinas' warmth was uniquely associated with children's responsibility only, whereas their control was uniquely associated with children's assertion and responsibility. Practice or Policy: Results extend previous research on the importance of nonparental caregivers for children's social development in a new cultural context. 相似文献

English language learners (ELLs) who experience slow vocabulary development are less able to comprehend text at grade level than their English‐only peers. Such students are likely to perform poorly on assessments in these areas and are at risk of being diagnosed as learning disabled. In this article, we review the research on methods to develop the vocabulary knowledge of ELLs and present lessons learned from the research concerning effective instructional practices for ELLs. The review suggests that several strategies are especially valuable for ELLs, including taking advantage of students' first language if the language shares cognates with English; ensuring that ELLs know the meaning of basic words, and providing sufficient review and reinforcement. Finally, we discuss challenges in designing effective vocabulary instruction for ELLs. Important issues are determining which words to teach, taking into account the large deficits in second‐language vocabulary of ELLs, and working with the limited time that is typically available for direct instruction in vocabulary. 相似文献

This paper analyses the psychological, technical, administrative, organisational, institutional and general pedagogical problems encountered during Phase 1 (the trial phase) of a trans-European distance-learning project. Using basic-rate ISDN videoconferencing for remote interactive tutorials, Phase 1 involved the University of Wales Swansea and HEC Liège (Belgium), and provided practice in business English for Belgian students and business French for UK students of French and Business. The difficulties which have arisen during the phase have been many and varied, and not all could have been easily predicted from a review of the research literature. Solutions to some of them are suggested. 相似文献
