The Development Of A Single Scale For Mapping Progress In Mathematical Competence, Ross Turner, Gayl O'Connor
The Development Of A Single Scale For Mapping Progress In Mathematical Competence, Ross Turner, Gayl O'Connor
Ross Turner
The authors’ intention is to develop a progress map that describes increasing mathematical competence. The main purpose of this chapter is to describe the means by which the research team has been able to use the data from a longitudinal testing program to build and refine a picture of growth in mathematical competence. In this chapter, conceptualisation of the underlying variable to be measured in developing a mathematical progress map is considered, and approaches to its development are discussed. The approach adopted is described and the results of the application of that methodology to the data generated through this research …

Assessing Second Language Writing: The Rater’S Perspective, Tom Lumley

This study investigates the process of rating texts written by adult ESL learners. Four experienced raters provided think-aloud protocols describing the rating process for a set of 24 texts. The think-aloud data allowed analysis of the sequence of rating, raters' interpretations of the scoring categories, and difficulties raters faced. The study reveals the complexity of the rating process, whereby raters struggle to resolve a tension between the wordings (or rules) of the rating scale and their complex, initial, intuitive impression of the text. Rating requires training to provide reliable measurement. The study also demonstrates that caution is needed in interpreting …
