Purpose: STEAM is the term given to a growing field of research and practice that integrates arts and social sciences into traditional sciences, technology, engineering, and mathematics subjects. The purpose of this study is to develop a STEAM-based educational learning package of social sciences textbooks and investigate its effect on the attitude, problem-solving ability, and creativity of sixth-grade primary school students of Bushehr in Iran. The design thinking model was used to design the training package. Methodology: The present study was quantitative applied research. The research design is quasi-experimental with pre-test and post-test with the experimental and control group (unequal control group). The statistical population of this study included all students studying in the sixth grades of public primary schools in Busher in the academic year 2020-2021. Due to the nature of the research which is quasi-experimental and also with respect to the subject drop, 44 participants were considered as the statistical sample (22 students in each group) and they were selected by "accessible" purposeful sampling and randomly divided into experimental and control groups. The STEAM training package was designed in 13 sessions and each training session took a 35-minute duration in the form of 14 projects, and its implementation lasted for 2 months. In order to design each social science lesson project, a focus group meeting was held with the members. Data were collected based on three questionnaires: Hepner and Kruskal's problem-solving skills test, Shaffer's creative attitude survey, and Aiken's scientific attitude test. The face validity of the educational package was confirmed using experts' opinions. In order to check the hypotheses of this research, covariance analysis was used. Findings: The presuppositions of the statistical test of covariance analysis, including the Kolmogorov- Smirnov test for the normality of the research variables and Levin's test for the homogeneity of the variances of the educational variables were confirmed. After that, the effects of the implementation of the steam-based educational package were investigated, and the results of the covariance analysis showed that the implementation of the educational package had an effect of (0.94) on creativity and problem-solving (0.90), and attitude (0.97) on students. The results of the Kolmogorov-Smirnov test showed that the creativity, attitude, and problem-solving skills variables of students have a normal distribution (p> 0.05). The results of the Levin test indicate that these assumptions are confirmed (p> 0.05). Conclusion: Based on the findings, it can be concluded that the STEAM-based training package increases problem-solving ability, creativity, and a positive attitude towards the course of social sciences.

Purpose: Considering the role of teachers' motivation in improving the teaching, educating and learning processes, the present study was conducted with the aim of providing a suitable model to promoting teachers' motivation for the education process. Methodology: The present study in terms of purpose was applied and in terms of implementation method was mixed (qualitative and quantitative). The research population in the qualitative part was the academic experts of Tehran city in 2020 year, which number of 15 people of them were selected as a sample according to the principle of theoretical saturation and by purposive sampling method. The research population in the quantitative part was the high school teachers of Tehran city in 2020 year, which number of 316 people of them were selected as a sample according to the Cochran's formula and by simple random sampling method. The research tool in the qualitative part was semi-structured interview and in the quantitative part was researcher-made questionnaire, which the validity and reliability of them were confirmed. The data in the qualitative part were analyzed by coding method based on grounded theory in MAXQDA software and data in the quantitative part were analyzed by exploratory factor analysis and structural equation modeling in SPSS and LISREL software. Findings: The results of the qualitative part showed that the central category included promoting teachers' motivation for the education process, causal factors included work environment, cultural and social context, teaching level, individual characteristics and demographic factors, intervention factors included psychological-attitudinal factors, individual-motivational factors, facility-welfare factors, managerial and structural factors and negation of work, contextual factors included financial rewards, school physical facilities and job enrichment and job development, strategies included planning to improve quality and academic level, behavior, attitude and policy educational of managers, teacher empowerment and encouragement active teacher and outcomes included trustworthy, academic competence, good social relations and understanding of circumstances and duties. Also, the results of the quantitative part showed that the factor load of all components was appropriate and work environment, cultural and social context, teaching level, individual characteristics and demographic factors on causal factors, psychological-attitudinal factors, individual-motivational factors, facility-welfare factors, managerial and structural factors and negation of work on intervention factors, financial rewards, school physical facilities and job enrichment and job development on contextual factors, planning to improve quality and academic level, behavior, attitude and policy educational of managers, teacher empowerment and encouragement active teacher and on strategies and trustworthy, academic competence, good social relations and understanding of circumstances and duties on outcomes had a significant effect on outcomes (P<0.05). Conclusion: According to the results of the present study, to promoting teachers' motivation for the education process can be action through the identified components in the present study.

Purpose: Women studies have always been of interest to researchers. The issue of women's presence in business and management is one of the most important issues in the field of women's studies. This study sets to investigate the effect of characteristics of female managers who were either member of board or CEO on earning quality. Methodology: To this end, we collected necessary data such as financial statements from 102 Tehran Stock Exchange listed companies. The data belongs to period stretching from 20 Feb 2015 to 20 Feb 2020. To test our hypotheses, multivariate regression with panel data and also EViews software were utilized. The results show that the presence of female managers has a positive as well as meaningful effect on earning quality. Findings: Furthermore, the results of our second and third hypothesis indicate that the training skills of female managers and their experience in the board have a positive and significant relationship with the quality of companies’ earnings. Conclusion: According to the results of the research, it is recommended that women be used more in managerial positions and the existing misconceptions that have prevented skilled and experienced women from appearing should be discarded.

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.
