This study evaluated the classification accuracy of a second grade oral reading fluency curriculum‐based measure (R‐CBM) in predicting third grade state test performance. It also compared the long‐term classification accuracy of local and publisher‐recommended R‐CBM cut scores. Participants were 266 students who were divided into a calibration sample (n = 170) and two cross‐validation samples (n = 46; n = 50), respectively. Using calibration sample data, local fall, winter, and spring R‐CBM cut scores for predicting students’ state test performance were developed using three methods: discriminant analysis (DA), logistic regression (LR), and receiver operating characteristic curve analysis (ROC). The classification accuracy of local and publisher‐recommended cut scores was evaluated across subsamples. Only DA and ROC produced cut scores that maintained adequate sensitivity (≥.70) across cohorts; however, LR and publisher‐recommended scores had higher levels of specificity and overall correct classification. Implications for developing local cut scores are discussed.  相似文献

In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.

The authors conducted a phenomenological study to explore the experiences of 32 school counselor educators preparing preservice school counselors. Analysis of data from 3 focus groups revealed 3 themes: breadth versus depth, balancing specialties and professor partiality, and preparation versus practice. These results highlight the need for collaboration across counseling specialties at the preservice level.  相似文献

The theoretical part of this paper argues for an embedding of the question of stability and change of teachers’ conceptions of learning into the researchers epistemological standpoint. The empirical part illustrates this statement by showing how changes in a teacher's conception of learning could be understood from a constructivist perspective. According to this perspective, conceptions are related to other relational and environmental variables that form a meaningful configuration. Thus, although conceptions of learning appear as relatively stable cognitive structures, they are also related to environmental variables to be managed by the teachers’ educators. This research result determines the discussion of the basic questions addressed in the title of this paper: why do we want to change teachers beliefs and how could we, as teachers’ educators, support these changes.  相似文献

A universal lack of attention to the professional learning needs of teacher educators is the driver for this study, which considers the most effective ways to support the professional learning of higher education-based teacher educators. At a time when many industrialised countries are engaged in systemic educational reform, this study provides an international and comparative needs analysis through a survey of 1158 higher education-based teacher educators in the countries participating in the International Forum for Teacher Educator Development: Belgium, Ireland, Israel, the Netherlands, Norway and the UK. Our results suggest that while teacher educators are only moderately satisfied with their professional development experiences, a strong desire exists for further professional learning. This desire, influenced by their professional context, relates to their current beliefs concerning ‘best practice’ in teacher education, the academic skills required to further their professional careers and knowledge of the curriculum associated with their fields of expertise.  相似文献

Student diversity has increased within Australian universities. This has changed the teaching and learning needs of students. The implementation of quality was aimed at enhancing the quality of the higher educational product. However, the policy, while providing an accountability framework at the institution level, failed to provide the structural mechanisms needed to achieve quality in the teaching and learning the students receive, that is the sub‐faculty level. Other factors, such as the potential growth of non‐government resources in the form of more international students have perhaps a greater chance of improving the quality of teaching and learning within the faculties, because they provide both the funds and an incentive for more funds as a reward for implementing quality assurance within the teaching and learning function of universities.  相似文献

A major investment in educational television programmes by the federal government led the United States Department of Education to seek ways to extend the audience size for these programmes beyond public television by placing them on commercial broadcast stations in America. This article describes the programmes, the marketing organization and strategies used to promote programming to the commercial marketplace, and the successes achieved in persuading commercial broadcasters to accept educational children's programming, particularly programmes aimed at minority audiences.  相似文献
