For the purpose of obtaining data to use in test development, multiple matrix sampling plans were compared to examinee sampling plans. Data were simulated for examinees, sampled from a population with a normal distribution of ability, responding to items selected from an item universe. (Author/LMO)

A taxonomic matrix classification was used to assess the curricular validity of the Stanford Achievement Tests for the mathematics textbooks used in a school district's fifth and sixth grades. Rasch item difficulty was also examined. Results indicated only small differences between textbooks. (GDC)

Peer reviewedForsyth, Robert A.; Spratt, Kevin F. – Journal of Educational Measurement, 1980
The effects of two item formats on item difficulty and item discrimination indices for mathematics problem solving multiple-choice tests were investigated. One format required identifying the proper "set-up" for the item; the other format required complete solving of the item. (Author/JKS)

Peer reviewedKirsch, Irwin S. – Journal of Educational Measurement, 1980
The construct validity of reading comprehension test items was studied in a two-stage process. Five characteristics of task difficulty were defined and a heterogeneous set of 52 items were rated for these characteristics. Then correlations were obtained between ratings and item difficulty data. (CTM)
