Purpose: the aim of the present study was to investigate the dimensions and quality of teaching-learning interactions by elementary teachers during the Covid-19 pandemic. Methodology: this was a qualitative study carried out using a phenomenological approach. The study population included all elementary school teachers in Abhar City (Iran). From this population, 12 individuals were selected as participants in the study using purposive sampling (chain sampling) who were engaged in online teaching from the onset of the Covid-19 pandemic. Data collection instrument included semi-structured or in-depth interviews performed in the Google meet interactive platform. The interviews continued until reaching data saturation. Data analysis was also carried out using thematic analysis and theme network formation. Validity was also assessed using peer review and member checking and reliability was assessed by text coding of three interviews by anonymous people outside the research. Findings: the results reflect the dimensions and quality of teaching/learning interactions by elementary teachers during the Covid-19 pandemic in the form of 226 basic themes, 21 organizing themes and 4 global themes. Conclusion: the results showed that elementary teachers had relatively acceptable interactions with themselves, students and parents during this process. However, there were no acceptable interactions between teachers and their colleagues.

Purpose: education plays a key role in empowerment of human resources. Thus, the present research was done to present and validate the human resources empowerment model with emphasis on education in the ornamental and building stone industry. Methodology: this descriptive-analytical study was of correlation type. The statistical population consisted of the staff at Iran's stone statistics and information center as many as 425 persons in 50 companies. The sample size was determined 200 according to Cochran formula; this number was chosen through stratified random sampling method based on the occupational unit. The research instruments included demographic information form capturing gender, age, level of education, years of working background, and a researcher-made questionnaire ( 50 items), whose face validity was confirmed based on expert opinion, while its reliability was calculated using Cronbach alpha method on 30 staff as 0.95. The data were analyzed by exploratory factor analysis and structural equations modeling methods in SPSS-25 and Smart PLS-3 software. Findings: the findings indicated that empowerment of human resources has 10 factors of change and innovation, managerial functions, learning, development of human resources, behavioral factors, organizational factors, the strategic factors of organization, environmental factors, cultural and leadership factors as well as knowledge beyond the technical knowledge. The factor load of all of its items was above 0.40; the convergent validity of the factors was found above 0.60 using the average variance extracted method. The reliability of all of the factors using Cronbach alpha and mixed method was above 0.70. Furthermore, the human resources empowerment model with emphasis on education in the ornamental and building stone industry had suitable and acceptable fitting, and the empowerment of human resources with emphasis on education had a direct and significant effect on all of the 10 factors (P<0.001). Conclusion: given the suitable model of human resources empowerment with emphasis on education in the ornamental and building stone industry, experts and planners can take effective steps for empowerment of human resources through the 10 identified factors.

Purpose: The purpose of the present research is to present a brain-based curriculum model focusing on interaction and motivation in the secondary school. Methodology: In order to achieve this goal, qualitative approach, field method and semi-structured in-depth interview techniques were used. The study population included prominent curriculum planning experts, researchers and faculty members and 15 people were interviewed based on the data saturation. The data collection tools included texts and semi-structured interviews, and the method of data analysis also included inductive thematic analysis (Attride-Stirling thematic networks). Findings: The results of the research showed that the curriculum design components included four dimensions: goals, content, teaching methods, and assessment methods, which affect students' interaction and motivation. Goals included indices of changing mental images, real learning environment, flexibility of brain-based curriculum, information storage during learning. Content included indices of development of brain ability, mechanism of brain function, cognitive learning, content understanding, triggering body and brain activity, teaching methods including practical learning, learning in the environment, cooperation in class activity, different learning style, getting students to take responsibility for learning, effectiveness of education, purposeful and conscious teaching, continuous information processing. Assessment method included self- assessment, understand the content easily, flexible learning, encouraging activities. The interaction included indices of sharing new experiences in learning; improving the brain ability; and discussing different topics. Stimulation of learning and motivation included the indices cognitive function of the brain, challenging and enjoyable learning. Conclusion: The results showed that the brain-based curriculum emphasizes on goals, content, teaching and assessment methods, which is designed with an emphasis on interaction and motivation.
