Mats Oscarson. Item Response Theory and Reduced Redundancy Techniques: Some Notes on Recent Developments in Language Testing. In the heyday of comparative investigations into language teaching methodology, some 20 years ago, researchers tended to be a little over-optimistic as regards the possibilities of disclosing "true" differences in attainment resulting from different experimental teatments. The statistical methods used for analysing test data were sometimes of a rather crude nature. The intention of the present paper, which falls into two parts, is to comment on some recent developments in these two fields, i.e. those of item data analysis and of test construction. A powerful analytic model, the so-ccalled item response theory, which is now coming into use in language testing, is briefly reviewed, and some advances in the development of testing techniques, particularly the close procedure, are indicated. It is suggested that developments such as these will improve the prospects for successful research into the relative effectiveness of contrasting language learning strategies, which is one of the topics of this Conference.
