Mapping Student Achievement, Geoff Masters, Ray Adams, Jan Lokan Aug 2013

Mapping Student Achievement, Geoff Masters, Ray Adams, Jan Lokan

Prof Ray Adams

The analyses, publications and reports of quantitative data in education and the social sciences usually omit basic information on the construct measured. Probabilistic models for test data make it possible to delineate coherent and richly described measurement continua that facilitate interpretation of student achievement. The potential of conjoint measurement to bring about fundamental advances in educational testing practice lies in part in the opportunities it provides to build useful maps of learning domains and to use those maps in communicating student achievements. This chapter presents two applications of conjoint measurement aimed at constructing and describing achievement variables, developing insights into ...

Issues In The Measurement Of Change In Reading Achievement Over Time, Petra Lietz Dec 1993

Issues In The Measurement Of Change In Reading Achievement Over Time, Petra Lietz

Dr Petra Lietz

The analyses reported in this paper seek to examine: (1)the factor structures underlying the tests employed in the Reading Comprehension and the Reading Literacy Studies. In particular, it is of interest whether or not the assumption holds of a common factor or trait, that underlies the processes involved in reading comprehension, as argued by Thorndike (1973a). If this were not the case, it would not be appropriate to calculate a total score which is necessary to equate student performance over time. Confirmatory factor analysis (CFA) is used to examine this issue. (2)whether or not similar results are obtained ...


Changes In Mathematics Achievement Over The High School Years, John Ainley Dec 1993

Changes In Mathematics Achievement Over The High School Years, John Ainley

Dr John Ainley

One of the important developments in the way achievement is used in studies of school and individual influences on learning has been the use of achievement growth rather than a static achievement score as an outcome. As part of a longitudinal study of students' progress through the later years of high school, mathematics achievement was assessed in Year 9 (in 1987) and Year 12 (in 1990). In both year levels students completed a modified version of the Progressive Achievement Test in Mathematics 3A. This test measures generalised mathematical performance rather than achievement specific to students' current studies. Scores at both ...

Cortical Type 2 Astrocytes Are Not Dye Coupled Nor Do They Express The Major Gap Junction Genes Found In The Central Nervous System, Daniel Belliveau, C. Naus Dec 1993

Cortical Type 2 Astrocytes Are Not Dye Coupled Nor Do They Express The Major Gap Junction Genes Found In The Central Nervous System, Daniel Belliveau, C. Naus

Daniel J. Belliveau

The O‐2A progenitor cell first described from the rat optic nerve is a bipotential precursor of oligodendrocytes and type 2 astrocytes. Each cell expresses specific markers that distinguish them as unique cell types. O‐2A progenitors cultured in high serum preferentially differntiate into type 2 astrocytes and when exposed to defined medium or low serum develop along the oligodendrocyte lineage. We analyzed the gap junction gene expression of type 2 astrocytes to determine if they are coupled to form a syncytium, like their type 1 astrocyte counterparts. Dye coupling experiments demonstrated that cortical type 2 astrocytes are not coupled ...


A New Approach To Standard-Setting In Language Assessment, Tom Lumley, B Lynch, T Mcnamara Dec 1993

A New Approach To Standard-Setting In Language Assessment, Tom Lumley, B Lynch, T Mcnamara

Dr Tom Lumley

In this paper the authors consider a standard setting exercise involving the Occupational English Test, a specific purpose test of English as a second language for health professionals. The Australian test is used as part of the screening of immigrant and refugee health professionals prior to the resumption of their professional careers in their new country of residence.
