词汇法在开放英语语法教学中的应用     

刘见平 《佳木斯教育学院学报》2013,(11)

语法教学在英语语言教学中占很大的比重。但由于受传统语法教学模式的影响,教师在进行语法教学时,往往只注重对语法结构及语法规则的讲解,结果导致语法教学难以收到预期的效果。分析其存在的问题之一就是语法和词汇的教学脱节。基于Halliday等人的观点,我们应该改变过去把语法和词汇孤立开来的做法,要注重词块的作用,注重语法和语境的结合,把词汇法应用于开放英语语法教学中,改变开放英语语法教学和词汇教学相分离的状况,以使教学效果达到最佳。  相似文献

Classroom Emotional Support predicts differences in preschool children's cortisol and alpha-amylase levels     

Bridget E. Hatfield  Linda L. Hestenes  Victoria L. Kintner-Duffy  Marion O’Brien 《Early childhood research quarterly》2013

Accumulating evidence suggests children enrolled in full-time child care often display afternoon elevations of the hormone cortisol, which is an indicator of stress. Recent advances in immunoassays allow for measurement of activity in the hypothalamic–pituitary–adrenal axis and the autonomic sympathetic nervous system from saliva, and measurement of both systems provides a more complete understanding of activity in the stress response system. This study is the first to examine both cortisol and alpha-amylase in children attending child care and focuses on the influences of specific indicators of classroom process quality. A diverse sample of 63 preschool children nested in 14 classrooms of varying quality participated in this study; child salivary cortisol and alpha-amylase were collected at six times over 2 days. Results indicate that children in classrooms with higher Emotional Support displayed a greater decline in cortisol from morning to afternoon. Further, children in classrooms with higher Emotional Support exhibited lower total alpha-amylase output while attending child care. Implications for professional development for early childhood teachers and measurement of classroom quality are discussed.  相似文献   

The Child Care Ecology Inventory: A domain-specific measure of home-based child care quality to promote social competence for school readiness     

Julie C. Rusby  Laura Backen JonesRyann Crowley  Keith Smolkowski 《Early childhood research quarterly》2013

This study investigates the reliability and validity of the Child Care Ecology Inventory (CCEI), a measure of the quality of family child care in the social domain. The CCEI focuses on research-based environmental features and caregiving practices for promoting positive social development in preschool-age children. A total of 198 family child care homes in the Northwest USA participated. Good scale reliabilities were found for the measures of the environment (Enrichment and Organization) and for caregivers’ practices (Monitoring, Positive Attention, Promoting Social Skills, and Teaching Rules) and interrater reliability was adequate for research purposes. The CCEI was associated with other commonly used measures of child care quality that assessed similar environmental and caregiving constructs. Linear regression models were run to determine the features of family child care quality that were concurrently associated with observed child behavior. The child–caregiver ratio, Environment Organization, and caregivers’ Teaching Rules were negatively associated with children's problem behavior (noncompliance and aggression). Caregivers’ provision of Planned Activities/Routines and Positive Attention were associated with positive child behavior. Results indicate that different aspects of quality are related to different aspects of children's social interactions and behaviors.  相似文献   

Multiple dimensions of family engagement in early childhood education: Evidence for a short form of the Family Involvement Questionnaire   总被引：1，自引：0，他引：1

The primary aim of this study was to develop and validate a short form of the 42-item Family Involvement Questionnaire (FIQ) for use in preschool. Empirical evidence derived from a representative sample of preschool programs in a large city in New York State with the original version of the FIQ was used to select the items for a 21-item short form. A representative sample of 590 Head Start families was also identified from a large Head Start program in Pennsylvania to serve to validate the short form. Confirmatory factor analysis of the short form substantiated the three robust dimensions of family involvement from the original FIQ. Concurrent measures of parental satisfaction and assessments of children's literacy and mathematics skills along with an examination of family demographic variables supported the validity of the confirmed dimensions. Implications for the use of this multidimensional, short form of family involvement in large-scale program evaluation were discussed.  相似文献   

Assessing dyslexia in Finnish high-school students: a pilot study     

Riitta Lehtola II  Juhani E. Lehto 《欧洲特需教育杂志》2013,28(3):255-263

A pilot study concerning Finnish dyslexics at senior high school (lukio), for 16–19-year-olds, is reported. The phonological processing deficit was assumed to underlie dyslexia in these late teenage subjects. The regular nature of Finnish orthography was taken into consideration. Four tasks were introduced to a total of 32 students, of whom 15 were dyslexics and 17 were controls. The controls outperformed the dyslexics on three tasks: text recoding, pseudoword recoding and pseudoword spelling. On the text spelling task, both groups performed equally well. In the correlational analysis of all subjects, both recoding tasks showed high correlations with selfestimated school achievement in language-related subjects. The recoding time appeared to be more important than the number of reading errors. These preliminary results suggest that the three tasks, capable of discriminating dyslexics, might be useful in the development of an adult dyslexia test in Finnish.  相似文献   

Assessing Students' Understandings of Biological Models and their Use in Science to Evaluate a Theoretical Framework     

Juliane Grünkorn  Annette Upmeier zu Belzen  Dirk Krüger 《International Journal of Science Education》2013,35(10):1651-1684

Research in the field of students’ understandings of models and their use in science describes different frameworks concerning these understandings. Currently, there is no conjoint framework that combines these structures and so far, no investigation has focused on whether it reflects students' understandings sufficiently (empirical evaluation). Therefore, the purpose of this article is to present the results of an empirical evaluation of a conjoint theoretical framework. The theoretical framework integrates relevant research findings and comprises five aspects which are subdivided into three levels each: nature of models, multiple models, purpose of models, testing, and changing models. The study was conducted with a sample of 1,177 seventh to tenth graders (aged 11–19 years) using open-ended items. The data were analysed by identifying students' understandings of models (nature of models and multiple models) and their use in science (purpose of models, testing, and changing models), and comparing as well as assigning them to the content of the theoretical framework. A comprehensive category system of students' understandings was thus developed. Regarding the empirical evaluation, the students' understandings of the nature and the purpose of models were sufficiently described by the theoretical framework. Concerning the understandings of multiple, testing, and changing models, additional initial understandings (only one model possible, no testing of models, and no change of models) need to be considered. This conjoint and now empirically tested framework for students' understandings can provide a common basis for future science education research. Furthermore, evidence-based indications can be provided for teachers and their instructional practice.  相似文献   

Girls and physics: teaching and learning strategies tested by classroom interventions in grade 11     

Peter Labudde  Walter Herzog  Markus P. Neuenschwander  Enrico Violi  Charlotte Gerber 《International Journal of Science Education》2013,35(2):143-157

In this quasi-experimental study various strategies are developed and empirically tested for an approach to physics instruction that should improve girls' and boys' attitudes toward and achievements in physics. Strategies include opportunities to integrate different pre-existing knowledge and the variation of teaching methods to enhance co-operation and communication in the classroom. The core of this study is an intervention in 31 classes of public schools in Switzerland. The intervention, one unit in optics and one in motion (velocity/acceleration), includes the first 40 lessons of the first physics course that all students have to attend at the upper secondary level. Data sources are various student and teacher questionnaires, tests and semi-structured interviews with teachers. Results of the entrance and final survey are presented. The focus will be on some of the applied strategies. Implications for the teaching and learning of physics and for teacher education are discussed.  相似文献   

Service ‘CUIDE'‐‐Coopération Universitaire pour l'Information et la Documentation des Enseignants

The ongoing reform in science education in many countries, including Israel, has attainment of scientific literacy for all as one of its main goals. In this context, it is important to provide teachers with the opportunity to construct meaning for the term science literacy and by doing so to obtain a clear understanding of the new teaching goals. Here we report on a study in which teachers, as part of their professional development, were involved in defining the term ‘chemical literacy’; they discussed the need for it, and suggested educational experiences that are necessary in order to attain it. The programme was conducted as part of a reform in the content, as well as in the pedagogy, of chemistry education in Israel. The collected data provide some insights regarding the process by which the teachers’ perception of ‘chemical literacy’ developed and the way actual school practice influences teachers’ perception of ‘chemical literacy’.  相似文献   

Assessing the efficacy of the Measure of Understanding of Macroevolution as a valid tool for undergraduate non-science majors     

William Lee Romine 《International Journal of Science Education》2013,35(17):2872-2891

Efficacy of the Measure of Understanding of Macroevolution (MUM) as a measurement tool has been a point of contention among scholars needing a valid measure for knowledge of macroevolution. We explored the structure and construct validity of the MUM using Rasch methodologies in the context of a general education biology course designed with an emphasis on macroevolution content. The Rasch model was utilized to quantify item- and test-level characteristics, including dimensionality, reliability, and fit with the Rasch model. Contrary to previous work, we found that the MUM provides a valid, reliable, and unidimensional scale for measuring knowledge of macroevolution in introductory non-science majors, and that its psychometric behavior does not exhibit large changes across time. While we found that all items provide productive measurement information, several depart substantially from ideal behavior, warranting a collective effort to improve these items. Suggestions for improving the measurement characteristics of the MUM at the item and test levels are put forward and discussed.  相似文献
