The aim of this study is comparing the effect of Dick & Carey instructional design model And Bybee instructional design model on students’ motivation and learning. The method of this study is Quasi-experimental and the research plan is pretest-posttest with two groups. The statistical society of this study included all female students in first year of high school in Shiraz. The statistical sample in this study was 54 female students and the available sampling was used. The data collection instrument was Herman's promotion motivation questionnaire and researcher-made learning test and in order to calculate the motivation questionnaire reliability, the Cronbach's Alfa method was used that its value was 0.87 and In order to calculate the reliability of learning test the Kuder Richardson 20 was used with the value of. /73. For data analysis, Covariance statistical test was used and the results showed that there is no difference between the Dick & Carey and Bybee methods in the rate of motivation, but there is a significant difference between Dick & Carey and Bybee methods in rate of learning and the Bybee method is more effective on students learning.

Access to the most basic standards of quality in higher education are the basic is one of the requirements for the administration of each of the approaches to improve quality assurance in higher education and the academic disciplines. The present study aimed to identify the factors, criteria and indicators affecting quality assurance of educational administration and determining and their priorities. The method was qualitative and the instruments were interviews and investigating documents. The findings on interviews and documents were analyzed using content analysis technique of categorization and Shannon Entropy technique, respectively. The semi-structured interview administered on 11 experts on quality assurance and faculty members of educational sciences in public universities of Tehran. In order to have a comprehensive identification of factors, criteria and indicators, 37 study units on evaluation and quality assurance of academic programs were considered. The results showed that “students”, “faculty members”, “educational facilities”, “organizational status, organization and management”, “teaching-learning process”, “programs”, and “graduates” are key factors in quality assurance of educational administration. Furthermore, the results showed that the factor namely, organizational status, organization and management having information load of 0.51and the significant coefficient of 0.17, had the highest priority among the factors. Criterion namely, “experience exchange” belonged to the factor of faculty members having information load of 0.688 and significant coefficient of 0.17, had the highest priority among all the criteria and the indicator of “the number of articles published in scientific journals” belonged to the same factor having information load of 0.800 and significant coefficient of 0.045, had the highest priority among all the indicators.

Interdisciplinary curriculum development is one of the strategies for reforming higher agricultural education. This qualitative research aimed to diagnose interdisciplinary approach in higher agricultural education based on Agricultural Extension and Education as a case. Information was gathered through semi-structured interviewing with a selected sample (n=44) of faculty members, researchers, experts, agents and managers of agricultural extension and education. Using multiple coding process of grounded theory, the interview's contents were analyzed. Findings were formatted in a matrix structure, including open codes, axial codes, and selective codes. According to matrix of findings, main issues and constraints of interdisciplinary approach in higher agricultural education classified in 6 conceptual categories in three area or level, as: theoretical and conceptual issues, educational and training issues, issues of research and delivering of research findings, professional issues (inside of interdisciplinary area), academic development issues (inside of university area), and institutional and operational issues (outside of university area).

The present research had done with the purpose of quality assessment of University of Qom Payam-e Noor's educational programs based on the NADE-TDEC pattern. This research's is a descriptive research and its approach is practical. Among all of the students (14232 students), 375 students were selected as a sample, with using a Quota sampling method. The data collection instrument was a researcher-made questionnaire and obtained data was analyzed by SPSS software with using descriptive and inferential statistics indicators. The assessment results showed; the quality of educational programs in a component for designing and course materials (3.14), Items relating to education (3.61), executive affairs (3.28) were more than average extent and in the components of new educational technologies had been used (2.49) is less than the average extent and didnt observed significant differences among comments of respondents in viewpoint of gender and academic background in the level of p <0.05. In regards to the situation of NADE-TDEC pattern’s components it is necessary for the University of Qom Payam-e Noor to take action to improve the quality of new educational technologies.

The purpose of this study is to investigate the effect of social capital and social responsibility on organizational commitment. The type of study was descriptive and the method was Survey. Data collection was by questionnaire which stratified random sampling was 203 of employees in Razi University in Kermanshah. SPSS- LISREL software was used for data analysis. The structural equation modeling analysis supported model fitting to the data. Results of structural equation modeling showed that: The direct effect of social responsibility on organizational commitment (0/21) is positive and significant. Also, direct effect of social capital on Organizational commitment (0/59) is positive and significant. As a result the factors that each organization should consider in order to organization's commitment is social responsibility and social capital. In the meantime establishing networks and communications in that field lead to the increased responsibility of staff that can be effective in increasing organizational commitment.

Computerized adaptive testing requires a well-designed item pool containing an appropriate number of items to build individualized tests. An optimal item pool should also contain well-balanced items that will achieve optimal item usage and low cost of item creation. One of the methods for designing the blueprint for an item pool is Reckase’s method, which is a Monte Carlo method to determine the properties of an optimal item pool. This study has been presented by the Reckase’s method for designing item pools calibrated with the three-parameter logistic model. Also, in the present simulation, the Sympson-Hetter procedure has been used to control the item exposure rate. To design simulation test items, three approaches including R, MRT, and MTI have been applied. The performance of the simulated item pools has been compared with the operational item pool by considering some evaluation criteria. The results suggest that the optimal pool designed with MRP performs the best, based on test security and measurement accuracy. It does require more items and some highly discriminating items. Tests assembled from MRP pools have smaller test-retest overlap rates and significantly lower percentages of over- and under-exposed items. The results show that the MTI design generally leads to smaller pools and contain items with lower a-parameters. Overall, Considering the Sympson-Hetter procedure, the optimally designed item pools perform better than the operational pool obtained from operational CAT.
