An Inventory of Adapting Variables.
Scheuerman, Karl
Three quantitative measures which assess instructional material in terms of the rationale of adapting are reported. The first index is termed the consequence ratio, which evaluates diagnostic items in terms of how effectively time is used. The second measure, termed predictive validity, evaluates the accuracy of diagnostic test predictions. The third index, discriminability, is a measure of how well the diagnostic test reflects individual differences. These measures have been included in a large field study which will assess the effectiveness of adapting techniques in meeting the needs of individual students. It is hoped, that by studying the actual parameters which reflect the rationale for adapting, a clearer picture of the future of adapting techniques in education will develop. For material to be truly adaptive it must score well on each of the measures. In the forthcoming field study these measures will be applied to a broad range of adaptive curricula. An analysis will reveal the contribution that adaptive features make to year end achievement test scores. (RC)
