Philip Carter's numerical competency test is graded using the rash model according to the characteristic curve theory of the individual

Abstract

    The current research is designed to test Phillip Carter's numerical efficiency using the Rush model according to the unique curve theory of the individual. To achieve this goal, the researcher relied on the precise steps in the development of the test starting with the translation of the test paragraphs and instructions from English to Arabic, taking into account the accuracy and comprehensiveness of all the ideas in the test, and then presented the instructions and test paragraphs consisting of (30) English to verify the sincerity of the procedure. It was then presented to a group of experts to ascertain the availability of the appropriate characteristics in terms of form and content. All sections of the tool were suitable for measuring what was set for measurement. The test was applied to 250 subjects from the preparatory stage randomly selected by the researcher.

The researcher relied on the Rash model (one of the models of the inherent characteristics) as a model for the analysis of the components of the test, and to make sure that the clauses of the tool for the model follow the following:

1. The Unilateral Dimension: To ascertain the procedure, the researcher analyzed the data in a global analysis. He obtained a factor (1) that is meaningful for the instrument. The interpretation of this factor was based on the Gitman criterion, which considered the factor to be statistically significant, Of (1).
2. The researcher adopted the criterion of the value of the square to accept the paragraphs at the level of significance (0.05) and according to what the program showed.
3. The coefficient of discrimination approached (1) for all paragraphs.
4. The researcher realized the local independence through the outputs of the program and the adoption of the single-parameter model.

 (6) paragraphs of the test were excluded because their values ​​were greater than the value of the square of Kai at the level of significance (0.05), thus the number of remaining paragraphs (24) in the total test
