Despite the popularization of the concept of brain hemispheric dominance, little serious research has been done in the area of the role of brain hemisphericity in learning and thought. The purpose of this case study was to explore the role of hemisphericity in the area of student composition to test the theory that the composing process and writing of student papers differs relative to the students' hemispheric dominance. A second area of investigation was to test the theory that teachers value papers written by students who share their hemispheric dominance.

The subjects, eight twelfth graders and four (English) teacher evaluators, …

Anchor Tests, Score Equating And Sex Bias, Geoff Masters

Prof Geoff Masters AO

This paper discusses the use of anchor tests (scaling tests) to bring two or more sets of scores to a common scale. Particular attention is given to the rescaling of school based assessments against an external test or examination and to potential sources of bias in this procedure. The need for routine validity checks is emphasised, and a latent trait approach to constructing a statistical framework for tests and examination score equating is described and illustrated. Bias caused by rescaling school assessments against an inappropriate anchor test is illustrated using a 1984 attempt to rescale students assessments in English against …

Item Discrimination: When More Is Worse, Geoff Masters

Prof Geoff Masters AO

This type of disturbance, which can be interpreted as a form of item bias, can be encouraged by methods that routinely interpret highly discriminating items as the best items on a test and may be compounded by procedures that weight items by their discrimination. The type of measurement disturbance described and illustrated in this paper occurs when an item is sensitive to individual differences on a second, …
