Teachers' Beliefs and Practices in Relation to their Beliefs about Questioning at Key Stage 2

This study examines the relationship between teachers' beliefs and their practices at Key Stage 2 (ages 7-11) in relation to the use of questioning. Data were collected from interviewing and observing Key Stage 2 teachers at four schools in the West of England. A Straussian approach to grounded theory is followed broadly in order to analyse the data. In contrast to the findings of previous studies, which suggested a mismatch between teachers' beliefs and practices in that teachers, in certain respects, do less than they claim, the research revealed that teachers use a variety of skills during their teaching that they may not always be aware of. It is also argued that teachers do not share researchers' language to express the way they teach.  相似文献   

DIF Detection and Effect Size Measures for Polytomously Scored Items

Data from a large-scale performance assessment ( N = 105,731) were analyzed with five differential item functioning (DIF) detection methods for polytomous items to examine the congruence among the DIF detection methods. Two different versions of the item response theory (IRT) model-based likelihood ratio test, the logistic regression likelihood ratio test, the Mantel test, and the generalized Mantel–Haenszel test were compared. Results indicated some agreement among the five DIF detection methods. Because statistical power is a function of the sample size, the DIF detection results from extremely large data sets are not practically useful. As alternatives to the DIF detection methods, four IRT model-based indices of standardized impact and four observed-score indices of standardized impact for polytomous items were obtained and compared with the R ² measures of logistic regression.  相似文献   

Student teachers in the classroom: their perceptions of teaching practice     

Cigdem Sahin Taskin 《Educational studies》2006,32(4):387-398

This paper examines student teachers’ perceptions of the course of school experience in a teacher education programme in Turkey. Data were obtained through interviewing student teachers in Canakkale Onsekiz Mart University, Turkey. In order to analyse the data, Strauss and Corbin’s grounded theory methodology was adapted. The analysis revealed that although the current teacher education programme put emphasis on effective practical training, in some circumstances student teachers feel that their chances of gaining real teaching experiences are minimal. The study suggests that there is a need for further strengthening the existing school–university partnership in teacher education.  相似文献
