[[alternative]]The Study on Construction and Application of Item Banking in Mathematical Diagnosis Test of the Elementary School

[[abstract]]The purposes of this study were to develop an item bank on mathematical diagnosis for elementart school, to validate the item bank by using "solve process by item type framework", and to make it on internet by WWW method. The items included in the item bank were divided into five forms. 16 commin items were used in two consecutive forms for linkage purpose. The data collected from target samples were analyzed by vertical equating techiniques using BIL OG-MG. The confirmatory factor analysis model were used to validate the content of item bank. The major findings of this study were as follow: 1.For the IRT modeling, from the goodness of fit index, the response data were mostly fit in two parameters IRT response model. 2.For the difference in mathmatical ability score (Θ), the interaction effect between sex and school reaches significance level. Male's score were significantly higher than female's. 3.Regarding the items' discrimation power(a), the interaction effect between solve proces and item type wasn' t significant. There were significant main effect for both solve process in a paramenter. From the plst hoc, The a parameters of understanding to problems were higher than the items of devising plan. 4.For the items' difficulty level(b), the interaction effect between solve process and item type wasn' t significant as a parameter. There were significant main effect for solve process, in the mean time, the results from post hoc showed that the items of divising plan are harder than the items of understanding to problems, carrying out plan and looling back. 5.Mathematic ability scores are significantly plsitive correlated with the schools mathematics achievement examination. 6.The response data wasn' t fitted well to 'sove process by item type framework' model. However, the result indicated acceptable convergent validity for both solve process and item type model. 7.A computerized version of the item bank was made and the homepage was located in httpd://epnet2.ecpsy.ntnu.edu.tw/~mathdiag. Baes on the results of this study, the researcher made suggestions in regaed to the research and future studies on the subject.
