University of California - Berkeley Professor Mark Wilson to Give 11th Annual William H. Angoff Memorial Lecture

PRINCETON, NJ -- (MARKET WIRE) -- April 27, 2007 -- Noted researcher and author Dr. Mark Wilson, a professor of policy, organization, measurement and evaluation at the University of California - Berkeley Graduate School of Education, will give the 11th annual William H. Angoff Memorial Lecture at ETS, where he will discuss the issues relating to the relationships between large-scale assessment and classroom-level assessment.

The lecture, which is open to the public, is scheduled for 3-4:30 p.m., May 31, at the Chauncey Conference Center on the grounds of ETS in Princeton. Interested attendees are asked to register for the lecture at

Wilson is an internationally renowned scholar in measurement, assessment and educational statistics. His lecture, "Linking summative to formative: a role for large-scale assessment in classroom assessments," will focus on the possibilities for taking advantage of learning progressions to link large scale and classroom assessments.

"In considering the relationship between assessment and educational accountability, it is important to keep in mind the two-way flow of information that it involves -- from the classroom out into the system and from the system back into the classroom," Wilson says. "In the 'standards-based' framework that is currently the most common accountability approach in the United States, the direction of this 'flow' is mainly from the system into the classroom. Insufficient attention has been paid to the central role of classroom-level measurements in our thinking about the role of assessment in educational accountability."

The issues relating to the relationships between large-scale and classroom-level assessments are also the topic of a book Wilson edited and published in 2004, "Towards Coherence Between Classroom Assessment and Accountability." His other recently published books include "Constructing Measures: An Item Response Modeling Approach," which gives an introduction to modern measurement, and "Explanatory Item Response Models: A Generalized Linear and Nonlinear Approach," which was co-written with University of Leuven's Paul De Boeck and introduces an overarching framework for the statistical modeling of measurements that makes available new tools for understanding the meaning and nature of measurement.

Wilson's work spans a range of issues in measurement and assessment from the development of new statistical models for analyzing measurement data, to the development of new assessments in subject matter areas such as science education, patient-reported outcomes and child development, to policy issues in the use of assessment data in accountability systems.

Wilson has recently chaired a National Research Council committee on assessment of science achievement: the report is titled Systems for State Science Assessment. He is founding editor of the new journal Measurement: Interdisciplinary Research and Perspectives, and actively participates on the editorial boards of numerous other publications.

William H. Angoff was a distinguished research scientist at ETS for more than 40 years. The Memorial Lecture Series established in his name honors his legacy by encouraging and supporting the discussion of public interest issues related to educational measurement. The annual lectures are jointly sponsored by ETS and an endowment fund established in Angoff's memory.
