The purpose of this study was to compare the effect of layer-by-layer, exploratory and online teaching methods in online virtual classes on mathematical academic achievement of elementary students. The research method was applied based on purpose and based on the method of data collection, quasi-experimental as pre-test-post-test. The statistical population included sixth grade male students in the primary school of Sanandaj who were studying in the academic year 2020-2021. The present study was conducted in coordination with three experienced teachers in three classes of 15 people, each of whom was in charge of a different teaching method. The number of teaching sessions was 8 sessions. SPSS software and analysis of covariance were used to analyze the data. The results show that the layer-by-layer teaching method has a higher average score (9.73, p<0.05) compared to the online and exploratory teaching methods. Accordingly, attention to new teaching methods, including the layer-by-layer teaching method, should be further studied and used.

The purpose of this study was to investigate the psychometric properties of the Covid-19 traumatic stress scale Which examines the effects of the corona virus on various aspects of Iranian life.

The present study was a descriptive correlational study. The statistical population included all adults in Tehran in the age range of 17 to 72 years. 461 people participated in the study through an online call. To analyze the data, Classical Test Theory and Item Response Theory were used and statistical software Spss version 26 and R software version 4.0.1 were used.

The results of the instrument validity study using exploratory and confirmatory factor analysis (classical theory) and multidimensional models (Item Response Theory) confirmed three factors related to the Covid-19 traumatic stress Scale. convergent and divergent validity of the instrument was also confirmed. The validity of the scale was confirmed by Cronbach's alpha method (alpha values above 0.70 for all three factors and the total score) and the retest method (high intra-class correlation between the two measurement steps) in the classical approach of the test. Based Item Response Theory, the validity of the data was assessed using the Information function and measurement error. The Information function showed that all three factors in the trait level range between 2- to 2 had the highest awareness and the least measurement error (p <0.05).

The Covid-19 traumatic stress scale has good validity and reliability in Iranian society and can be used as a valid scientific tool to assess the effects of the Corona virus on various aspects of Iranian life.

The purpose of this study was to investigate the construction and standardization of professional competencies of teachers. The present study was applied in terms of purpose and in terms of data collection type, correlation. All teachers in Qazvin province in the academic year of 2017- 2018 were the statistical population of the present study. The sample consisted of 618 participants who were selected by cluster sampling method. To collect the data, a researcher-made scale of professional competencies of teachers was used that contained 56 items and 10 components. Data were analyzed using SPSS and LISREL software's and through content validity in Lawshe method, exploratory and confirmatory factor analysis, principle component analysis, orthogonal rotation with varimax rotation, confirmation factor analysis, fitness indexes, and Cronbach’s alpha . The results of content validity in the Lawshe method indicated that the teachers' professional qualifications scale was appropriate. The analysis of the main components showed that the professional competencies of teachers from 10 factors including knowledge, professional ethics, classroom management, effective teaching, creativity and innovation, cooperation and interaction, assessment of learning, research, technology Professional information and development were formed and the results of the confirmatory factor analysis indicated the proper fitting of the factors with the data. Cronbach's alpha for each component was higher than 0.65 and for the whole scale was 0.97. Based on the results, one can use the professional competence scale of teachers as a valid tool for assessing the professional qualifications of teachers.

The relationship and awareness between the children and their teachers and parents is one of the most important steps to make an effective relationship between them. Its years that this matter has attracted the attention of educational and breeding expert to itself. Parents and children can provide a situation for there to see their logical and correct behavior by deing aware of their emotions and the amount of management which the children can have on thir emotions. The aim of this study is to standard the tail to evaluate the Psychometric properties of emotional and emotional management tool among primary school children referring to Faramoz centers of southern Tehran. The sample of 257 learners from faramooz center that cover 10% of total clients. data were analyzed using exploratory factor analysis ( varimax rotation) and Cronbach’s alpha using spss-24 software and maximum likelihood using lisrel 8.72 software . The result showed kmo=0.779 / Bartlett’s sprite test with chi-square approximation 585.917 and initial value for all three factors greater than 1.0 In the proposed model reported was RMSEA=0.72 df=51 CFI=0.93 NFI= 0.90 RFI=0.87 IFI:0.93. The alpha value for the first factor was 0.738 the second factor was 0.823 and the third factor was 0.820 and the total reliability of the questionnaire was 0.847 .In total the questionnaire has acceptable reliability and validity.

The purpose of this study was to determine the psychometric properties and the confirmatory factor structure of Islamic Spiritual Intelligence Scale (ISI) Abdul Rahman & Shah (2015) in students of Zanjan University using a confirmatory factor analysis approach. The participants of this study were 197 Students University of Zanjan in the academic year 2015-2016 who were selected by multistage random sampling method. To Assessment the adequacy of the model of Chi Square Index (2χ), the chi-square of the degrees of freedom 2 χ / df)), fit index of the adaptive (CFI), root mean square residual standard (RMSEA) and the index of fitness relative (RFI) has been used . In order to investigate the construct validity of the Islamic Spiritual Intelligence Scale, exploratory and confirmatory factor analysis was used. The results of the analysis are three factors that explain %66.76 of the common variance. In addition Confirmatory factor analysis indicates that model fit the data is acceptable. Cronbach's alpha coefficient and split-half also indicates that the scale has good reliability.

In this study, The questionnaire of perceived parenting practices (POPS) prepared by (Grolenyic et al, ) was standardization on high school students in Tehran. high school students ( girls and boys) were selected on through random multistage cluster sampling in Tehran city. Factor analysis was implemented using the principal components method with rotated varimax. Results of exploratory factor analysis and fit indices of confirmatory factor analysis confirmed the existence of six factors Perception of involvement, autonomy and warmth in the parents separately, that explained the total " of the variance. Internal consistency, reliability coefficients were obtained for total scale ( ) and for six the sub-Scales, mother involvement ( ), mother autonomy ( ), mother warmth ( ), father involvement ( ), father autonomy ( ), father warmth ( ), which are indicating generally acceptable instruments with internal consistency coefficients. Also ANOVA test results comparing boys and girls showed, boys perceived better than girls perception (p< ).
