A Method for Estimation of Difficulty and Discrimination Indices in Programed Learning. Comparative Studies of Principles for Programming Mathematics in Automated Instruction, Technical Report Number 10.

Rosen, Ellen F.; Stolurow, Lawrence M.

In the development of programed materials, usually all responses are analyzed for a small sample of students. The viable alternative is to perform mathematical transformations on response data from a selected portion of a large sample (more than 400 students) to obtain reliable estimates of item difficulty and item discrimination.
