Ahmad Borjali Associate professor in group of psychology, Faculty of Psychology and Education, Allameh Tabatabaei University, Tehran, Iran Journal Article 2015 11 30 The main goal of this research was to apply the multi-level in determining the role of metacognitive components associated with drug abuse among adolescents of Kerman Province. The method used in this research was correlation type. In order to conduct this research 1000 school students of Kerman Province have been selected by using multistage cluster sampling method. For data collection in this research, ZARGAR drug addiction preparation Questionnaire and Wels’s Metacognitive Questionnaire (MCQ30) have been used. The results of multi-level approach using One-way random effects Anova showed that the four components (positive beliefs about worries, negative beliefs about worries, low cognitive trust and cognitive self-awareness) explained about 49% of the variance of addiction tendency at school level. Moreover, the random intercept model explained 12% of the student-level variance of drug abuse tendency. Here, the significance of qi-square with the value of 37.983 at the significant level (P <0.0001) reflects the significant change of the null model and model 1. In response to the question that how much the relationship between the tendency to drug abuse and student-level components is similar among schools, a comprehensive model with both student-level and school-level variables (model 2) was used. In model 2, the results showed that at the school level, the mean of positive beliefs and cognitive self-awareness about drug abuse tendency have a significant relationship, but the mean of cognitive trust and negative beliefs has not a significant relationship with the tendency to drug abuse. At the students level, there is a significant relationship between cognitive trust and negative beliefs with drug abuse tendency (P <0.01). In total, it can be said that for variables related to samples with a nesting nature, it is necessary to use all levels in data analysis.

The data examined in this study included responses from 3,000 participants in the graduate entrance examination for English language field, which were selected from among 16044 people randomly. At first, with the help of experts, a matrix Q, consisting of the relationship between 20 questions of reading test with 7 basic skills was formed and then, using the G-DINA model, last analysis was performed. Finally, using a posteriori expected method within the framework of the G-DINA model, probability of domination of every single person on each skill was calculated by CDM package skills in software R, and by determining the cut-off point 0.6 for dominance, investigated participants in each skill, divided into two dominant and non-dominant groups. The results showed that in each of the skills, most people have not reached to dominance, Although the situation in the SUM skill (Analyzing and evaluating the relative importance of the information contained in the text, by differentiating between the main idea and details) was better than other skills, and about half of those got dominant in the skill. The final result suggests that, in general, the participant's situation in the application of cognitive strategies to achieve the correct answer is unsatisfactory and these strategies must be included in the curriculum of reading skills and comprehension.

Besides, the founded DIF items were gone through a content analysis in order to explore the potential linguistic resources of such biases. To this end, the answer sheets of 2217 female and 735 male examinees in 2015 were analyzed to find items containing DIF. The findings of LR technique determined eight items as DIF containing items. Half of the items were advantageous to the men and the other half of the items favoured women. MH procedure explored eleven items as DIF flagging items. Out of these items, six items favoured male test takers and five items showed tendency toward female test takers. No particular linguistic source for such deviated behaviour of items was proposed through the content analysis of the DIF items.

For this purpose, a sample of 100 individuals (2 girls and 2 boy's classes) was selected randomly in a multi-stage method; then, a class (male and female) as an experimental group and a class (male and female) Was selected as the control group. The experimental groups received a course in a portfolio evaluating, but control groups received standardized measurements. For data collection in pre-test and post-test, Hermann's motivation questionnaire and researcher-made academic achievement test were used. Data analysis using multivariate analysis of variance (MANOVA) for differential scores showed that there is a significant difference between motivation and academic achievement in two groups of measurement and portfolio assessment. That is, students who had received a portfolio assessment had a higher degree of motivation and academic achievement than control groups who received standardized measurements. In addition, the portfolio assessment on the motivation and academic achievement of elementary school-boy students has a significant effect; and on the motivation achievement of female students in the third elementary school has a significant effect, but on the academic achievement of female hasn't a significant effect. Measurement-gender interaction was also significant.

The overall goal of this study was to assess the psychometric properties items of "natural number bias test". To achieve this goal, a comprehensive test was constructed to test 7 and 9 graders’ natural number bias. This test had 62 tasks which administered on 181 secondary school students at Kerman in a pencil-and-paper form. After of pilot administration of test, data was collected and were analyzed by item response theory modeling. Data analyzing by R software has shown acceptably fitting whit dichotomous rash model. After removing 7 Item, the test had high diagnostic value in its purpose. Results showed that a natural number bias could be found on secondary student in all three aspects. The most difficulty was for "density" items and least difficult was for "size" items. "operations" items were scattered across the Rash scale. Most students were in the top questions test scale.

In this research, after a brief explanation of the local dependency indices and its models, In order to modeling the structure of cognitive abilities based on the data obtained from the implementation of the scale of cognitive abilities on a sample of 1105 students from the 9th grade students of Ahwaz selected by proportional stratified random sampling, after examining the hypothesis local independency through local dependency indices, monotonicity hypothesis and estimation of parameters of two one-dimensional and two-dimensional models and their comparison, The dimensionality of cognitive abilities was determined. The results showed that the dependency model observed between the data is perfectly locally dependent and Comparison of fitness indices of one-dimensional and two-dimensional model of Samejima graded response model showed that the two-dimensional model has better fit to the data than the one-dimensional model. In the following, using the concept of dimensionality factor space, a kind of comparison between the two classical test theories (CTT) and multidimensional item response theory (MIRT) was created and a kind of convergence in the results was obtained. The results showed that the fitness indices of classical theory alone were not able to characterize the structure of cognitive abilities, and methods based on item response theory in this field can be solved. The results of dimensionality analysis showed that the structure of cognitive abilities was two-dimensional; the first dimension of non-social cognition and the second dimension of social cognition were named and it was observed that these results converge with the results in the field of neuroscience.
