A Structure For Quality Mathematics Instruction, Hilary Hollingsworth, David Clarke Dec 1997

A Structure For Quality Mathematics Instruction, Hilary Hollingsworth, David Clarke

Dr Hilary Hollingsworth

The intention of the authors in this paper is to set out a possible structure by which teachers might incorporate the products of recent curriculum initiatives into their mathematics teaching. They have chosen to focus on Chance and Data as the academic content of their examples.

David (Dave) Tout

Outlines the rationale and development of a curriculum for adults based on realistic purposes and uses of mathematics, and discusses its potential for use with secondary students who are not coping with a more formal curriculum.


Bias In Weighted Likelihood Estimation When Using The Rasch Model, D Roberts, Ray Adams Dec 1996

Bias In Weighted Likelihood Estimation When Using The Rasch Model, D Roberts, Ray Adams

Prof Ray Adams

There are three methods of maximum likelihood estimation that are commonly used with Rasch item response models: Joint maximum likelihood, which provides point estimates for both person and item parameters; conditional maximum likelihood, which produces estimates for the item parameters only, and marginal maximum likelihood, which produces estimates of the item parameters and parameters of the distribution from which it has been assumed that the persons have been sampled. A number of approaches have been suggested for obtaining ability estimates for subsequent use in reporting or analysis when either conditional or marginal methods have been used to obtain the item …
