Abstract:
يهدف البحث الحالي استعمال انموذج راش للاحتمال اللوغاريتمي لاعداد اختبار الاستدلال التخطيطي لدى طلبة جامعات بغداد. ولتحقيق هذا الهدف, اتبع الباحث الخطوات العلمية في اعداد الاختبار بدءا بترجمة فقرات الاختبار والتعليمات من اللغة الانكليزية الى اللغة العربية، | The Present Study aims at Preparing The Diagrammatic Reasoning TestFor the Students Of Baghdad Universities. To Achieve this aim, Scientific Steps are followed Starting with the Translating the Items and its Instructions from English into Arabic, then re - translated the Arabic version into English, taking into consideration the accuracy and comprehensiveness of the whole ideas included in the test. Several modifications are required by translation experts and which were considered later. Then the Arabic version of the test is exposed on an Arabic Language expert who recommended certain modification in the style of the Arabic translation, and which were all taken into accont. The final Arabic version of the test is exposed on a number of experts in the field of Educational and Psychological Sciences in order to check its suitable characteristics as well as those of the alternatives with respect to form and content. Consequently all the test items are considered logically suitable to achieve the aim of the present study. The test is applied on a pilot sample of (20) male and female students in order to ensure the clarity of the test items and instruction, and to estimate the time required to respond to the test and which is fond out to be (50) minutes. The test Has applied on a stratified random sample of (500) male and female university students from the stage, morning studies in the formal universities in Baghdad. Rasch model for logarithm probability has been employed, which is one of the latent trait models, to analyze the components of the test. To verify the model assumptions, the following steps has been employed : 1. Uni - dimension : To verify this assumption factorial analysis of the test is applied by using the essential components. One meaning full factor of the test is obtained which is interpreted by the lower limits of Guttmann which considers the factor to be statistically significant since its Eigen value equals or up the one, and depending on a ratio of 0.30 - up to the items saturation ratio by the general factor according to Guilford's norm. No item has been deleted from the test by the applied statistical program. In addition to this method, the compellation coefficient method is applied by finding out the relation of the items come to the total score of the test. which shows that all the items have been statistically significant and positive through comaring it with the tabulated value on (498) degree of freedom and (0.05) level of significance.2. Matching the items of the model depending on the (Chi² value) according to the outputs of the program. 3. Because of the range of the compellation coefficient did not exceed ( 0, 426 ) , Amean is ( 0,338 ) , Astandard deviation ( 0, 171 ). So these values indicate to values discrimination to each test items is symmetric.4. Measurement independence which achieves objectivity represented by Rasch's model, for no item is eliminated.5. In order to get rid of fractions and negative signals (i.e. minus), the logget unit is changed in to the percentile WAT unit to find out the items difficulty and the individual's ability estimation. In the light of the statistical analysis above, suitable conclusions, recommendations, and suggestions for further studies are put forward.
