The purpose of this study was to investigate the factor structure, validity and reliability of the Community of Inquiry framework survey instrument. This research is a non-experimental research that has been done by descriptive-analytic method. The population of this study was all students enrolled in the web-based courses in the academic year of 1395-1396, a sample of 271 students selected by convenience sampling from a number of universities offering Web-based courses at the master's level and responded to the Arbaugh et al(2008). Community of Inquiry framework survey instrument. The results of exploratory factor analysis by the principal components method, confirmed three cognitive, social and educational presence factors. To assess the reliability of the questionnaire, Cronbach's alpha coefficient was used and the confirmatory factor analysis was used to determine its validity. The results showed that the questionnaire had an acceptable internal consistency and the Cronbach's alpha coefficients were between 89.8 and 5.96. Also, for determining the factor validity, a confirmatory factor analysis was used which results showed that the questionnaire appropriately fit with data. All of the fittest's goodness indicators confirm the model. As a result, it can be said that the translated version of Community of Inquiry framework survey instrument among Iranian learners is acceptable.

Aims:Thepresent research aimed to evaluate the factor validity of Motivated Strategies for Learning Questionnaire (MSLQ) in a group of Iranian students. Method: The population included all third-grade students who were studying Humanities in Tehran. Using multi-stage cluster sampling, a total number of 337 students (176 females and 144 males) were selected and answered the MSLQ. In order to determine the factor validity and internal consistency of the Questionnaire, confirmatory factor analysis and Cronbach's alpha coefficient were used respectively. Findings: Confirmatory factor analysis showed that the factor structure of the questionnaire was appropriate to measure intrinsic goal orientation, extrinsic goal orientation, task value, control of learning reliefs, self-efficacy for learning and performance, test anxiety, rehearsal, elaboration, organization, critical thinking, meta-cognitive self-regulation, time and study environment, effort regulation, peer learning, and help seeking which could empirically support the internal validity. In addition, the internal consistency coefficient for the questionnairesubscales was reported as 0/78 to 0/91. Conclusion: providing some evidencesfor supporting the theory of self-regulated learning, findings of the research showed that the MSLQ possessedgood psychometric propertiesand consequently can be used as a diagnostic and research instrumentfor measuring the cognitive and metacognitive strategiesin Iranian sample.

Background: The issue of achievement or non-achievement in the realm of education is an important concern in education systems of all societies. Students and university students’ education achievement is indicative of the extent that the education system has been in setting the goals and satisfying individual demands. Education resilience is an individual variable influencing education achievement. Objective: The present research aims to study the factor reliability and validity of the academic resilience inventory, constructed by Samuels (2004). Method: Two sample populations were involved in this study. The first sample included 300 male and female subjects randomly selected from among public high school students in the city of Boukan, Iran. The second one included 319 male and female subjects who were selected from among Allameh Tabataba’i University students, using cluster sampling method. Cronbach’s alpha coefficient was used to examine reliability of the questionnaire, and exploratory factor analysis, including principal component analysis and confirmatory factor analysis, was performed to confirm factor validity. Results: The evaluation of the first analysis scree plot was indicative of a three-factor solution. Then, to obtain the three-factor structure, the principal component analysis was performed through the varimax rotation. 11 questions were eliminated because they had a factorial load below 0.3, or had significant value or equal load on more than one factor. Finally, the analysis was performed on the remaining 29 questions. Conclusion: These three factors were named according to their comprising content with the following names: communication skills, future orientation, problem-oriented approach, and optimistic orientation. Cronbach’s alpha coefficient for the subscales ranged from 0.63 to 0.77 in the high school students sample and ranged from 0.62 to 0.76 in the university students sample. This shows that reliability of the three-factor model is at an acceptable level.
