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   

How schools tackle bullying,and the use of whole school policies: changes over the last decade     

Muthanna Samara  Peter K. Smith 《教育心理学》2008,28(6):663-676

Surveys were carried out to assess the UK government’s anti‐bullying pack Don’t suffer in silence in 1996 (after the first edition) and 2002 (after the second edition), to investigate what schools are doing about bullying, and the effect of anti‐bullying policies becoming a legal requirement. Schools in England were approached, randomly but within the constraint of having a spread across geographical regions. In 1996 109 schools and in 2002 148 schools were asked about school policy, interventions, and bullying frequency. Most schools moved from having a bullying policy as part of a broader policy on behaviour and discipline, to having a separate anti‐bullying policy. More schools attempted to survey the extent of bullying and there were changes in the use of particular interventions. Most interventions were rated as moderately useful. Some variations in use and satisfaction between different school levels were found. The implications of anti‐bullying work at schools and its success are discussed.  相似文献   

Enhancing curriculum and delivery: linking assessment to learning objectives     

Kathryn L. Combs  Sharon K. Gibson  Jane Saly  John T. Wendt 《Assessment & Evaluation in Higher Education》2008,33(1):87-102

Typical university‐wide course evaluations do not provide instructors with sufficient information on the effectiveness of their courses. This article describes a course assessment and enhancement model where student feedback can be used to improve courses and/or programs. The model employs an assessment tool that measures student perceptions of importance and their current competence in course‐specific learning objectives both pre‐ and post‐course. Information gained from this assessment enables course improvement over time and also allows for modification in delivery and/or content of the current course. This model is intended to augment traditional course evaluation mechanisms based on specific and actionable feedback on learning objectives.  相似文献   

Measuring need for closure in classroom learners     

Teresa K. DeBacker  H. Michael Crowson 《Contemporary educational psychology》2008,33(4):711-732

Need for closure, as formulated by Kruglanski and colleagues [Kruglanski, A. W. (1990). Lay epistemic theory in social-cognitive psychology. Psychological Inquiry, 1(3), 181–197; Kruglanski, A. W., & Webster, D. M. (1996). Motivated closing of the mind: Seizing and freezing. Psychological Review, 103, 263–283; Webster, D. M., & Kruglanski, A. W. (1994). Individual differences in need for cognitive closure. Journal of Personality and Social Psychology, 76(6), 1049–1062], refers to the motivated tendency to seek structure, simplify complex information, and avoid ambiguity. In this article, we argue that this motive may impact classroom learning in important ways and introduce a self-report measure of need for closure situated in the classroom learning environment. Psychometric properties of the new measure are assessed in multiple samples using exploratory and confirmatory factor analysis. Correlations between the new measure and existing indicators of cognitive closure, as well as variables known to influence motivation and academic achievement, support our assertions regarding the association between need for closure and academic functioning while also providing evidence for the construct validity of the measure. Finally, internal consistency and test–retest reliability suggest that the new measure functions as a reliable measure of need for closure within the classroom.  相似文献   

Restructuring reforms in Turkish teacher education: Modernisation and development in a dynamic environment     

Gary M. Grossman  Margaret K. Sands 《International Journal of Educational Development》2008

The paper examines the effectiveness of recent reforms in teacher education in Turkey, specifically the restructuring of programmes in university faculties of education. It first, briefly, sets the reforms of the 1990s in an historical context, prior to the 1997 Act which increased the length of compulsory schooling from 5 to 8 years, and the 1998 restructuring of faculties of education. It considers the national need for the restructuring of teacher education and the issues involved. The thrust of the paper is a study of how teacher educators across the country perceive both the changes and their effect on the quality of teacher education, methodology as a discipline, school partnerships, and relationships with the Ministry of National Education.  相似文献   

A Hong Kong case of lesson study—Benefits and concerns     

Jackie F.K. Lee 《Teaching and Teacher Education》2008

In recent years, there has been a feeling that effective teachers can be fostered by grounding professional development in actual classroom practice. This paper reports how a group of teachers adopted a lesson study approach and worked collaboratively so as to improve their class instruction on wh-question formation. Teachers’ reflections indicate that the collaborative environment throughout the study enabled them to gain insights into how to improve their teaching strategies. Also identified are some of the problems faced by teachers, which may undermine the gains of lesson study.  相似文献   

Co-constructors of data,co-constructors of meaning: Teacher professional development in an age of accountability     

Leyton M. Schnellert  Deborah L. ButlerStephanie K. Higginson 《Teaching and Teacher Education》2008

This research examines how engaging teachers in collaboratively constructing situated assessments enhances teacher professional development, fosters meaningful shifts to practice, and supports productive conceptions of accountability. We conducted case studies of six teachers engaged as partners in investigating new approaches to assessing and fostering literacy. Findings suggested that supporting teachers to generate, interpret, and act upon assessment data within instructional change cycles assisted them in monitoring student performance, grounding instructional decisions in data, and enacting changes to practice. We also document how collaboratively constructing assessments with teachers supported conceptions of accountability considered meaningful by individuals adopting differing socio-political perspectives.  相似文献   

Evaluating fifth- and sixth-grade students’ expository writing: task development, scoring, and psychometric issues   总被引：1，自引：0，他引：1  

Jonna M. Kulikowich  Linda H. Mason  Scott W. Brown 《Reading and writing》2008,21(1-2):153-175

Drawing from multiple theoretical frameworks representing cognitive and educational psychology, we present a writing task and scoring system for measurement of students’ informative writing. Participants in this study were 72 fifth- and sixth-grade students who wrote compositions describing real-world problems and how mathematics, science, and social studies information could be used to solve those problems. Of the 72 students, 69 were able to craft a cohesive response that not only demonstrated planning in writing structure but also elaboration of relevant knowledge in one or more domains. Many-facet Rasch Modeling (MFRM) techniques were used to examine the reliability and validity of scores for the writing rating scale. Additionally, comparison of fifth- and sixth-grade responses supported the validity of scores, as did the results of a correlational analysis with scores from an overall interest measure. Recommendations for improving writing scoring systems based on the findings of this investigation are provided.  相似文献   

Fermion number fractionization     

Kumar Rao  Narendra Sahu  Prasanta K. Panigrahi 《Resonance》2008,13(8):738-751

Solitons emerge as non-perturbative solutions of non-linear wave equations in classical and quantum theories. These are non-dispersive and localised packets of energy — remarkable properties for solutions of non-linear differential equations. In the presence of such objects, the solutions of Dirac equation lead to the curious phenomenon of ‘fractional fermion number’. Under normal conditions the fermion number takes strictly integral values. In this article, we describe this accidental discovery and its manifestation in polyacetylene chains, which has led to the development of organic conductors.
