Reforming The Assessment Of Student Achievement In The Senior Secondary School, Geoff Masters, P Hill Dec 1987

Reforming The Assessment Of Student Achievement In The Senior Secondary School, Geoff Masters, P Hill

Prof Geoff Masters AO

The challenge that confronts agencies responsible for assessment and reporting in the senior secondary school is to extend systematic assessment procedures to broader range of learning outcomes than those currently assessed by public examination, to develop methods of reporting which are more descriptive of individual achievement and which provide a better basis for describing and maintaining standards, and to provide results which are sufficiently comparable across schools to enable fair comparisons of applicants for tertiary study. Some recent developments in assessment and reporting practice are considered with a view to identifying methods and approaches capable of satisfying this diverse set …


Anchor Tests, Score Equating And Sex Bias, Geoff Masters Dec 1987

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 …


The Analysis Of Partial Credit Scoring, Geoff Masters Dec 1987

The Analysis Of Partial Credit Scoring, Geoff Masters

Prof Geoff Masters AO

This article discusses a range of issues in the practical application of an item response theory (IRT) method for partial credit scoring. After a brief discussion of partial credit scoring as an alternative to right-wrong scoring in the measurment of educational achievement, an IRT model for partial credit analysis is developed and described. This model is presented as a straightforward and logical application of Rasch's dichotomous model to a sequence of ordered response alternatives. The distinctive nature of the item parameters in the model is described and these parameters are contrasted with two more familiar sets of parameters: Thurstone thresholds …


Item Discrimination: When More Is Worse, Geoff Masters Dec 1987

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, …
