The present paper responds to defenses of statistical significance testing offered by Levin and Robinson. First, some inaccurate perceptions of contemporary criticisms of statistical tests are noted. Second, areas of disagreement are explored. For example, it is noted that all nine empirical studies of reporting practices since 1994 show that encouraging (per the 1994 APA style manual) authors to report effect sizes has not worked; two reasons for this failure are explored. Finally, two important areas of agreement regarding needed improvements in contemporary practices are noted.相似文献
The paper attempts to throw light on the direct (instructional) cost of OU teaching methods as against conventional “live” instruction. The variable cost per student-course is with one exception lower in the OU than elsewhere. This constitutes a strong case for the use of existing OU packages in campus universities, especially as campus universities might feel able to dispense with the costs of the summer schools. It also constitutes a case for expansion of existing courses at the OU. As regards the development of new OU packages, the paper shows the Foundation courses to be much cheaper than equivalent provision de novo at the same scale in campus universities. Measured by the breakeven number of students, second-level courses in a given faculty are cheaper than foundation level courses. But they also have fewer students and some are operating at levels which, if there were no interdependence between courses, might be considered expensive. If however they were used by more students either at the OU or at campus universities they could be economic, even when taken on their own. The paper does not cost student time but, if this is cheaper when OU teaching methods are used, this is a further argument in their favour.
ABSTRACTThis paper describes the aims, origins and principles of the Australian National Exceptional Teaching for Disadvantaged Schools programme and reflects on findings from its first eight years. As a well-established, mainstream university-based initial teacher-education programme designed to prepare social justice teachers for low socio-economic or high-poverty schools, NETDS has had significant impact on recruiting and retaining high-performing teachers in the schools that need them most. In this paper we discuss how it works, but also outline some of the complexities that arose in trying to design a teacher-education programme with equity at the centre and some of the changes we made along the way. 相似文献
Self-assessment is a powerful technique for improving achievement. In this article we outline a theory of teacher change that links self-assessment by teachers to their professional growth. This theory provides avenues for peers and change agents to influence teacher practice. We apply the theory to change in mathematics teaching and report an explanatory case study in which use of the self-assessment tool, in combination with other elements, contributed to change in the instructional practice of a grade 8 mathematics teacher. Provision of a self-assessment tool contributed to teacher growth by: (1) influencing the teacher's definition of excellence in teaching and increasing his ability to recognize mastery experiences; (2) helping the teacher select improvement goals by providing him with clear standards of teaching, opportunities to find gaps between desired and actual practices, and a menu of options for action; (3) facilitating communication with the teacher's peer; and (4) increasing the influence of external change agents on teacher practice. The study argues that providing a self-assessment tool is a constructive strategy for improving the effectiveness of in-service provided it is bundled with other professional growth strategies: peer coaching, observation by external change agents, and focused input on teaching strategies 相似文献
Although textbooks on educational research give only scant attention to survey research methodology, its extensive use in education provides a strong rationale for improving the preparation of educational researchers in effectively applying survey methods. This study reviews methods for dealing with nonresponse bias, the primary problem presented by survey methods. It also provides an updated review of the literature of studies investigating the effectiveness of incentives to increase survey response rates. We hypothesized that a reanalysis of reviewed studies, using a linear trend test, would resolve the inconsistencies found regarding the effectiveness of incentives to increase response rates. The results of the reanalysis and guidelines for educational researchers in systematically selecting and applying incentives to increase response rates are discussed. 相似文献
This article explores ways the Performance-based Research Fund (PBRF) produces gendered results and expresses a cultural cringe. It is argued that the research evaluation is fixated with being ‘world-class’ at the expense of academic practice that focuses on New Zealand. In this context, disadvantage faced by female academics under the PBRF can be re-imagined as an exemplar of a broader experience faced by all New Zealand-trained and focused academics. At the same time, the PBRF has produced some embarrassing results for neoliberal policy-makers and somewhat empowers academics as arbiters of excellence by reifying elements of peer review. 相似文献
This paper reviews what is currently known about the genetics of dyslexia and shows how genetic studies can help clarify which
symptoms are primary and which are secondary in dyslexia. On the genetic side, current evidence supports the view that dyslexia
is familial, substantially heritable, and heterogeneous in its genetic mechanisms. At least some forms of familial dyslexia
appear to be autosomal dominant, with linkage studies supporting both a major locus on chromosome 15 and genetic heterogeneity.
On the symptom side, current evidence supports the view that the primary symptom in dyslexia is a deficit in the phonological
coding of written language. This primary symptom likewise appears to be heritable. Recent evidence suggests that the heritable
precursor to this written language deficit is a spoken language deficit in the skill of phoneme segmentation and awareness. 相似文献
