This cross-national study provides new insights in teacher efficacy in today’s culturally diverse classrooms using survey data of 269 early childhood and primary school teachers in England, Italy, the Netherlands and Poland. Teacher efficacy can be viewed as a two dimensional concept in which both general beliefs are measured alongside (diversity-related) domain-specific beliefs. These beliefs are related to the cultural classroom context and the use of intercultural classroom practices. Our results indicate that policies and professional development targeted at the reciprocal relation between diversity-related efficacy and practices are important when preparing teachers for working in diverse classroom contexts.  相似文献

Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed.  相似文献

The goal of the Standards for Educational and Psychological Testing is to improve testing practices, but their impact on practice appears spotty. Self-regulation clearly fails in some instances. The establishment of an external agency to oversee testing practices and adherence to the Standards would face substantial hurdles, and the ambiguity of many of the Standards would hobble such an organization if one were created. Many of the Standards are general statements of principle, and past controversies make clear that we in the field often disagree about the reasons for them, their applicability to specific cases, and their practical meaning in specific contexts. This paper argues that the field should follow two approaches to lessen this ambiguity. First, using journals, conferences, and other vehicles, we should foster more frequent and more protracted debate about the practical meaning of key Standards, such as 13.6 and 13.7, which mandate that a decision that will have a "major impact" on a student should not be based on a single score. Second, future revisions of the Standards should use concrete examples of testing practices to clarify the meaning of the Standards, much as the legal system uses case law to clarify the meaning of the general principles embodied in statutes .  相似文献
