Methods For Improving Test Efficiency And Accuracy In A Computer Adaptive Test (Cat)

View page
US Patent:
20150161899, Jun 11, 2015
Filed:
Dec 5, 2014
Appl. No.:
14/562167
Inventors:
- Iowa City IA, US
Changhui Zhang - Coralville IA, US
Nancy Petersen - Solon IA, US
Lingyun Gao - Coralville IA, US
International Classification:
G09B 7/00
Abstract:
A method for use of pretest items in a test to calculate interim scores is provided. The method includes, for example, a computer implemented test having a plurality of test items that include, for example, a plurality of operational items and one or more pretest items having one or more pretest item parameters. An interim latent construct estimate is calculated using both operational and pretest items. The error for the latent construct estimation is controlled by weighting the contribution of the one or more pretest items.

US Patent:
20150161901, Jun 11, 2015
Filed:
Dec 5, 2014
Appl. No.:
14/562187
Inventors:
- Iowa City IA, US
Changhui Zhang - Coralville IA, US
Nancy Petersen - Solon IA, US
Lingyun Gao - Coralville IA, US
Wugen Dai - Iowa City IA, US
International Classification:
G09B 7/00
Abstract:
A method for test item selection is provided that includes a computer implemented test battery having at least two or more sections with a plurality of test items. An ability estimate is calculated from an earlier section(s) of the at least two or more sections and an initial item and subsequent items for a subsequent section are selected from the plurality of test items based upon the ability estimate(s) from the earlier section(s). Use of a more informative initial ability estimate in the item selection process can improve interim ability estimation accuracy and item selection efficiency while keeping item exposure and item usage rates at acceptable levels.
