What time may tell: Towards a new conceptualization of developmental dyslexia

This paper is a written version of the Norman Geschwind Lecture delivered to the International Dyslexia Association on November 13, 1998. The first purpose is a theoretical one: to describe a new conceptualization of reading disabilities, the double-deficit hypothesis, that depicts and integrates work on two core deficits in the phonological system and in processes underlying naming speed. Implications for subtyping, diagnosis, and, in particular, intervention are described. The second purpose is to thank the women and men whose commitment to children with reading disabilities has transformed our field over the last century. Within that double set of purposes, I wish to dedicate this paper to five research teachers whose insights have been the foundation for my work and the efforts of many of us in the field of reading disabilities research: Jeanne Chall, Carol Chomsky, Martha Bridge Denckla, Helen Popp, and especially, Norman Geschwind.

Instructional Tools in Educational Measurement and Statistics (ITEMS) for School Personnel: Evaluation of Three Web-Based Training Modules

In the current No Child Left Behind era, K‐12 teachers and principals are expected to have a sophisticated understanding of standardized test results, use them to improve instruction, and communicate them to others. The goal of our project, funded by the National Science Foundation, was to develop and evaluate three Web‐based instructional modules in educational measurement and statistics to help school personnel acquire the “assessment literacy” required for these roles. Our first module, “What's the Score?” was administered in 2005 to 113 educators who also completed an assessment literacy quiz. Viewing the module had a small but statistically significant positive effect on quiz scores. Our second module, “What Test Scores Do and Don't Tell Us,” administered in 2006 to 104 educators, was even more effective, primarily among teacher education students. In evaluating our third module, “What's the Difference?” we were able to recruit only 33 participants. Although those who saw the module before taking the quiz outperformed those who did not, results were not statistically significant. Now that the research phase is complete, all ITEMS instructional materials are freely available on our Website.

The International Adult Literacy Survey: What Does It Really Measure?

The paper evaluates the work of the International Adult Literacy Survey as reported in OECD 1997. It assesses its contribution to understanding literacy in terms of the perspective of the New Literacy Studies. It outlines this perspective as a basis for a critique that is mostly concerned with the validity of the test. Three criticisms of the survey are made: that it provides only a partial picture of literacy; that culture is treated as bias; and that the test items do not represent the real-life items as claimed. Finally, the paper concludes with an overall evaluation of what the IALS achieves in terms of its own aims.
