Abstract

The present study considers the Comparing differences between estimating examinable ABILITY PARAMETER and estimating ABILITY PARAMETERs in the scale of Raven excessive entelligence based on the Rush model and three-parametric model in item Response theory. For this purpose, among all high school girl students in Tehran, who enrolled the 2007-8 school year, 498 participants were selected by multistage random sampling method. The scale was administrated on the sample. The results showed, The RELIABILITY coefficient was estimated using Cronbach's a of scale Raven excessive matris equal to 0.839. Using the principle component analysis. The scale of five factors is saturated. Factor structure of the obtained includes five factor: General intelligence, understanding And mathematical talent, Memory, The spatial visualization, Speed. Of implementation of one -parametric & THREE- PARAMETRIC MODEL and compare these two models the results showed: 1- There is a meaningful correlation between one-parametric and three-parametric models regarding the estimating personal ABILITY but between The two models are different regarding the estimating personal ABILITY. 2- People's ABILITY is predictable from raw scores. 3- Comparing the mean score of the two models is indicated that one-parametric model is more refractory than the three-parametric model.
