The Influence Of Brain Hemisphericity On The Composing Process Of Twelfth Graders, Reinholdine Breien-Pierson

Theses and Dissertations in Urban Services - Urban Education

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, …

G88-883 Managing Of Disease To Produce Antibiotic/Residue Free Animal Food Products, Duane Rice, R. Gene White

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the use of antibiotics in animals, approved drugs and extra-label drugs, and ways to test for drug residue. Infectious diseases in livestock are costly, and prevention is the best approach to minimize such losses. Yet despite good management practices and extensive preventive measures, disease outbreaks do occur, and treatments become necessary. To obtain antibiotic residue-free products from food animals, knowledgeable decisions regarding the use of medications are necessary. It is important to realize that antibiotic treatments are used only to eliminate or shorten the duration of existing infections, or to prevent secondary bacterial infections. These infections may …

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

High item discrimination can be a symptom of a special kind of measurement disturbance introduced by an item that gives persons of high ability a special advantage over and above their higher abilities. 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, …
