Purpose: The purpose of this study was to compare the effect of KWL educational strategy and conceptual mapping strategy on students' critical thinking. Methodology: This research was based on a quasi-experimental design with pre-test and post-test with two experimental groups and one control group. The statistical population consisted of all male students of the third grade high school of Miandoab in 2016-17. Three classes were selected through multistage cluster sampling. Two classes were randomly selected as experimental group and one class as control group. One of the experimental groups was taught in KWL and the other in a conceptual map. The control group was also trained in a conventional way. The pre-test and post-test data were used to collect data from the California Formation B Questionnaire. Findings: To analyze the data was used one-variable covariance analysis. The findings of the study showed that education through the Kwl strategy and conceptual mapping strategy is effective on critical thinking students (P <0.001). It was also determined that the effectiveness of KWL strategy on students' critical thinking was more than conceptual mapping strategy (p <0.001). Conclusion: Based on this study, both cognitive strategies and metacognitive strategies reinforce students' thinking. However, due to the findings of this research and related studies, it is better to use metacognitive strategies along with cognitive strategies because using metacognitive strategies, students monitor their learning process and become more aware of complex issues and points and they get more aware. Based on these findings and previous research, it is recommended that modern educational methods such as KWL and concept maps be used in teaching

Purpose: The purpose of this study was to identify the dimensions and components of organizational agility based on human resource development to provide a model of organizational agility in the Islamic Azad University of Tehran. Methodology: The present study was a mixed type (quantitative and qualitative) and at the same time it was an applied research. In this regard, the statistical population of the study includes all employees of the Islamic Azad University of Tehran in 2015- 17, which was about 6735, and using Morgan table and Cochran's formula and multi-stage cluster sampling method and relative 386 employees of the university as The sample size was considered. Data collection method was based on a researcher-made questionnaire, research literature and semi-structured interviews. And Cronbach's alpha coefficient of research tool was calculated 0.919. After distributing and collecting the questionnaires, reviewing the information and testing the hypotheses was done using structural equation modeling and SPSS, LISREL software. Findings: Finally, the research findings confirmed the five dimensions, strategic, information technology, human, organizational and cultural, as dimensions affecting organizational agility based on human resource development. The results showed that the strategic dimension of the highest average and dimensions of information technology and human, organizational and cultural are in the next ranks. Finally, confirmatory factor analysis showed that the dimensions of organizational agility based on human resource development up to 71.282%, the variance of existing indicators of organizational agility based on human resource development explains. Conclusion: From the perspective of the studied sample, respectively, dimensions: strategic, information technology, human, organizational and cultural in the scale of measurement (1 to 4) have been important to a large extent and very much in organizational agility based on human resource development.

Purpose: The purpose of this study was to investigate the appropriateness of the content of the educational network - growth information with the educational needs and interests of its users. Methodology: The present study was applied in terms of purpose and descriptive in terms of implementation method. The research community of students and teachers of the second-high school of Nazarabad city were in the academic year of 2018-19. The sample size was calculated according to the Cochran's formula of 345 students and 105 teachers, who were selected by multi-stage cluster sampling. The research instrument of the researcher-made questionnaire had two forms of student (41 items) and teacher (34 items). Their formal and content validity was confirmed by 10 experts and its reliability by Cronbach's alpha method for both student and teacher forms were 0.98. Was obtained. At the descriptive level, data analysis of central orientation and scattering indicators including mean, standard deviation, frequency and frequency percentage were used, and at the inferential level, t-test was used to test statistical hypotheses. Findings: The findings of the present study showed that the average content of the educational network - growth information in terms of needs and interests of students and teachers and their five dimensions in both groups including knowledge needs, skill needs, attitude needs, interests and thinking ability and problem solving below It was moderate (P <0.05). Conclusion: Due to the incompatibility of the content of the educational network - growth information with the educational needs and interests of students and teachers, it is necessary to design and prepare appropriate content after proper and comprehensive educational needs assessment.
