|
The model for educational measurement developed by George |
|
Rasch, a Danish psychometrician, is reviewed and its |
|
application to occupational educational testing |
|
discussed. The Rasch model is an adaptation from the |
|
theory of latent trait analysis. According to it, |
|
answering an item correctly is a function of the |
|
difficulty of the item and the ability of the person |
|
being tested. The raw scores serve as the basis for |
|
estimating the scale of ability. The author concludes |
|
that the properties of the Rasch analysis suggest |
|
solutions to a number of measurement problems in |
|
occupational engineering including developing and |
|
equating alternate forms of a test and estimating and |
|
interpreting changes in trainee performance. The item- |
|
free characteristics of this measurement model may allow |
|
the development of individually tailored tests. (DJ) |
