Development of Computer Package Usage for Item Analysis.

Abstract

The objectives of this study are 1) to develop a microcomputer package for test item analysis called ITEMPC, 2) to develop a manual for using ITEMPC, 3) to analyze multiple choice test item response by using ITEMPC and 4) to compare ITEMPC results with SPSS/PC+. ITEMPC is a microcomputer package that teachers can use to do multiple choice test item analysis. Information available from ITEMPC consists of 3 parts 1) test statistics, including mean, standard deviation, the K-R 20 reliability coefficient, frequency distribution and inter-correlation matrix between scale scores; 2) test item information, including frequencies and percentage of each selected option, item facilities or item difficulties, point-biserial correlation between the score on the individual item and the sum of the scores on the remaining items and flags for four different levels of significance testing of point-biserial correlations; and 3) individual information, including test scores and the response of each item. Seven entrance examination tests for master students of Department of Education at Kasetsart University are analyzed by using ITEMPC and SPSS/PC+. All the results from those two packages are the same.
