Abstract

Waxy-leaved mustard (Boreava orientalis Jaub. and Spach.) is an invasive species recently reported in Kurdistan province in western Iran with allelopathic properties. To evaluate the effect of the extract of different parts of waxy-leaved mustard on wheat germination, an experiment was conducted as a factorial based on a completely randomized design in the Faculty of Agriculture, University of Kurdistan, Iran. The allelopathic potential of waxy-leaved mustard's root, leaf, stem, and flower were evaluated, and secondary metabolite compounds were identified. Effect of Alcohol extracts at concentrations of 0, 1, 2, 3, and 4% of roots, leaves, stems, and flowers of waxy-leaved mustard were evaluated on wheat germination Indicators. Increasing extract concentration significantly increased the inhibition of seed germination and caused a decrease in germination rate, reduction of stem length, and reduction of seed vigor index. Alcoholic extracts of waxy-leaved mustard flowers had significantly more effect compared to the alcoholic extracts of roots, even at the lowest concentration (1%). The results of this study show that waxy-leaved mustard has a strong allelopathic potential, which emphasizes the importance of reducing its allelopathic effects and developing effective management strategies for mitigating invasion risk and thereby protecting crops like wheat.

Abstract

Many of the existing problems of teachers arise from the lack of a written supervision program, and the implementation of educational supervision in principle can not only be effective in solving the problems of teachers, but also increase their motivation.
Therefore, having an educational observation model can be effective in optimizing the performance of educational consultants. The purpose of this study was to investigate the effectiveness of the educational supervision model in French language classes in Iran using the situated action theory.
This study was performed by quasi-experimental pretest-posttest single-group method.The statistical population included all educational consultants, 7 of whom were selected by convenience sampling. The dependent variable (monitoring quality) was measured before and after the implementation of the independent variable (monitoring optimization model).
Comparing the mean score of supervision quality in the group of counselors before and after the educational intervention and according to the results of the study, the mean score and standard deviation before the intervention (19.07 11 111.42) and after the intervention (22.13 15 155.85) was obtained Based on the paired t-test, according to the level of significance obtained, a statistically significant difference was observed between the mean scores before and after the intervention. Therefore, training of educational consultants based on the proposed supervisory model was effective at a significant level (p <0.05).
According to the research findings, it can be concluded that, by using the designed model of educational supervision, educational consultants can be trained with effective quality of performance, because the principles of educational supervision can be learned and this in turn   leads to success in the teaching-learning process.


1. Introduction
Educational supervision has an essential role in the quality of teaching and optimizing the performance of teachers. Many of the problems that teachers face are due to the lack of a written supervision program. The task of educational counselors is to train and accompany teachers in acquiring the skills they need in teaching and coping with different classroom situations. Training counselors seldom engage in in-depth thinking and provide feedback and solutions that are primarily prescriptive. In addition, the beginner teacher-counselor relationship is associated with a kind of dishonesty during post-supervision interviews, and educational counselors resort to covert methods to avoid tension with teachers and to improve the relationship.
Due to the lack of quality training courses, training consultants are more inclined to supervise as they teach. For this reason, the lack of expertise has made the practice of educational counseling a simple and aimless oversight. Implementing educational supervision in a principled way can not only be effective in solving teachers' problems, but also increase their motivation. In Iran, educational counselors generally work as educational counselors in educational centers without having to participate in a special training course, and this lack of expertise causes problems such as low productivity, pessimism, frustration and teachers’ lack of motivation. Because not every good teacher necessarily becomes a good educational consultant (Sadidi et al., 1398).
The application of some educational monitoring models based on observation method can examine in-depth practical dimensions and observable actions such as gesture, movement in space, etc., and on the other hand investigates the living dimensions of action, perceptions, feelings, concerns and Pay attention to the action; It can help to optimize the quality of the educational consultants' supervisory performance. The "situated action theory" is based on two factors; observation method "within the living organization" and interview, simulation and relative experience techniques.  For these two reasons, the efficiency of the educational supervision is to be materialized through these two ways: Encouraging the teacher to reconsider his or her action in the classroom and interpreting his or her action. This theory seeks to return the actor to the situation. Here the actor is asked to explain his action. This clarification is done via his cognitive and social re-visualization with the aid of the characteristics of the situation.
This theory seeks to return the actor to the situation in which the action was performed and to re-visualize him socially and cognitively, using the characteristics of the situation, to lead the actor to explain his action. This theory studies the cognitive dimensions of human activities, because we are dealing with role-makers who are in the role of teachers, educational supervisors, language learners, etc., for whom the skill of adaptation, which is specific to any living thing, is of special importance. Therefore, in the case of teachers and educational supervisors who are the actors of this study, it is necessary to study their human activities and their experience in interacting with the environment and the meaning of their actions. Therefore, the purpose of this study was to determine the effectiveness of the model of educational supervision of French classrooms in Iranian language schools, using the theory of situational action.
Research Question(s)
This study seeks to answer this question:
  Is the model of educational supervision effective on the quality of supervision of counselors in French language classes in Iranian schools?

2. Literature Review
No research has been done on the background of the research in the general study, at the school level and in the field of French language, on issues related to the status of supervision and supervisory models in Iran, and this article is the first research in this regard.
  However, in the field of English in the same field, at the level of education and high school, academic research, dissertations and articles have been presented and published. Numerous articles and researches in this field have been presented in foreign countries, some examples of which are mentioned below.
Bullunz et al. (2014) implemented a clinical supervision model to train Turkish teachers in their research and evaluated its effectiveness. They used experimental and control groups to compare the performance of teacher trainee training and used t-test and analysis of variance to compare scores.
The results showed significantly higher scores in the experimental group compared to the control group, however, the results of repeated measures analysis (ANOVA) did not show a significant difference in increasing scores for both groups, which was probably due to the limited time to implement the clinical monitoring model.
In another study, Rashidi and Forutan (2015) in examining the status of monitoring the performance of English language teachers in the Iranian education system, stated;
 Most English language teachers rated their supervisors' professional skills as effective in areas such as assessment, classroom management, educational activities, student behavior, and teaching techniques and these teachers wanted more support from educational supervisors in the areas of preparing and editing educational materials, developing teachers' experience, and teaching guidance. The supervisory model applied in high school is traditional models, especially the prescriptive model, and the supervisory model of supervisors in university teacher training centers is followed by a model of self-thinking or thinking. The vast majority of regulatory model volunteers prefer self-reflection to traditional models, and educational supervisors consider themselves skilled and specialized in most areas.
Sobhaninejad and Aghahsseini (2006) found in their research that there is a significant difference between the current monitoring situation and the desired and optimal situation. The results of Hismanoglu (2010) research show that, the most important part of monitoring education is motivating and encouraging teachers to overcome their weaknesses. After examining the current situation, his research had two main conclusions: 1: there is a clear difference between teachers 'beliefs about educational supervision and their experiences, and 2: there is a significant difference between teachers' expectations of supervision and the perception of educational supervisors.
Sadeghi et al. (2015) have shown that the current state of educational supervision is almost acceptable, but teachers expect to receive more qualified services in supervision and they need more support in the field of educational supervision and counseling. When teachers associate the supervision of educational supervisors with evaluation, they become distrustful (Bushama et al., 2016).
Jecker-Parvex (2020) in his research examined the role of educational counselor and defined educational supervision as an educational and practical method that aims to develop teacher skills, acquire self-assessment skills and analyze interaction situations, challenges such as interventions and Professional issues, especially in terms of responsibilities, contradictions and problems, effects and emotions, and obstacles and performance of their profession.
According to the researches mentioned in the previous articles, various studies have been conducted in the field of education in the field of supervision models, and there are still no results that indicate the use of a comprehensive model that includes all aspects and the present study is one of the first studies to investigate the effectiveness of a supervisory model in French classrooms in Iranian language schools using the theory of situational action.

3. Methodology
                                                This study was performed by quasi-experimental method of pre-test-post-group test. The statistical population included all educational consultants and 7 of them were selected by convenience sampling. The dependent variable (monitoring quality) was measured before and after the implementation of the independent variable (monitoring optimization model). In this research, the educational supervision model of French language classes, which is designed by Sadeghpour (2020) based on the theory of position-based action with a mixed quantitative-qualitative exploratory approach; was used.
To determine the effectiveness of Sadeghpour (2020) educational supervision model, an educational plan was designed and the quasi-experimental research design method was used. The dependent variable (monitoring quality) was measured before and after the implementation of the independent variable (monitoring optimization model) and based on the educational supervision model, a 42-item researcher-made educational supervision checklist was designed to determine the effectiveness of using the optimized educational supervision model, which included items with 5-point Likert scale (very low, low, medium, high, very high) and sought to answer the question of whether the model of educational supervision of French classrooms in Iranian schools using the theory of position-based, on the quality of supervision of counselors , Is it effective? To perform the pre-test, to view and complete the checklist, the performance of each educational counselor before the training course was filmed and reviewed and the monitoring table was completed by the researcher. Then, the educational intervention was carried out by forming a "group workshop" and "individual accompaniment" and to run the post-test again, including the previously mentioned steps; (Monitoring, filming, etc.) was done and the checklist of the monitoring table was completed again and finally the results were compared with each other.
4. Results
Comparing the mean score of quality of supervision in the group of counselors, before and after the educational intervention, the mean score and standard deviation were obtained before the intervention (19.07 ± 111.42) and after the intervention (22.13 ± 155.85) and based on the paired t-test, according to the obtained level of significance, a statistically significant difference was observed between the mean scores before and after the intervention. Therefore, training of educational consultants based on the proposed supervisory model was effective at a significant level (p <0.05). Table 1, shows the mean and standard deviation of pre-test and post-test scores, and Table 2, shows the significance of the mean of pre-test and post-test scores.

5. Discussion
The results of the study showed that the model of educational supervision of French classrooms in Iranian schools is effective on the quality of supervision of counselors by using the theory of position-based action and there was a significant difference between the means before and after the training. This means that the proposed training course has been useful in optimizing the educational supervision situation, and the current shortcomings of the educational supervision situation can be partially eliminated. Thus, effective teaching supervision and counseling leads to the development of innovation, positive motivation and initiative in teachers.
The training counselor should be able to know the knowledge and skills, attitudes, needs, expectations of the instructor and also be aware of the expectations of the training center and the effectiveness of the instructor.
The training course should also be an opportunity for training counselors to develop their counseling and leadership skills; to be able to act more effectively during class situations and during post-visit interviews. The training course should also be an opportunity for training counselors to develop their counseling and leadership skills; to be able to act more effectively during class situations and during post-visit interviews. They need to understand the needs of educators and, through practical and theoretical integration, guide them to find solutions to their problems (Chaliès et al., 2009, p. 106).
If the educational supervision is done properly, it will lead to the quality of the teacher's performance and ultimately improve the quality of the educational situation.
Therefore, it is necessary for educational institutions to emphasize this type of supervision and use and teach effective and appropriate models of educational supervision to educational consultants.

6. Conclusion
According to the research findings, it can be concluded that, by using the designed model of educational supervision, we can train educational consultants with effective quality of performance. Because the principles of educational supervision can be learned, and this, in turn, leads to success in the teaching-learning process. In this study, in terms of typology, to optimize the quality of supervision of educational consultants in Iran, the model obtained from a mixed quantitative-qualitative exploratory study by Sadeghpour in 2020 was used, Considering the effectiveness of this model, doing more research by combining related models can lead to more comprehensive regulatory models in this regard.

Abstract

In the second half of the sixteenth century, Shah Tahmasp drawn his back on the field of art, court supporting of the art and artists was minimized and the political events after the death of Shah Tahmasb added the complexity of the situation. This situation forced Sadiqi Beg to adopt the suitable strategy in accordance with the new relations governing the field of culture. This strategy was to turn to personal habitus and rely on own individuality. The present study, while paying attention on the historical relations and social developments affecting the second half of the sixteenth century’s Safavid art, has emphasized the relations between activists in the field of culture, the personal motivations of the artists, or the effect of these relations on his final function. The main target is to understand the relationship between the function of the artist (here Sadiqi Beg) and the influential forces in the art scene of sixteenth century. As a result, the artist’s specific function in relation to the dominant discourse has been examined and recognized. In order to strengthen the mentioned concepts, the performance of Sdiqii contemporary artists such as Aghareza and Alireza Abbasi has also been briefly discussed To find this relationship and draw its coordinates, primary historical sources and documents have been analyzed and interpreted. Therefore, the quiddity of this research is qualitative and historical and with the descriptive-explanatory method has been analyzed the special and symbolic function of Sadiqi Beg during the social and political changes of that time. The analytical approach used in interpreting texts, reports, and functions in this article is the issue of Pierre Bourdieu’s relational sociology. This approach led us to realize that the relations in the field of Safavid art and culture in the second half of the sixteenth century were such that it forced the activists presents in it to act according to their personal habitus and the amount of symbolic capital at their disposal. They chose the appropriate strategy with the requirement of the field, and in this regard, they followed the laws governing the field of politics and power.

Abstract

In recent decades, digitalization has emerged as a key factor in the transformation of industries. Along with the advances that digitization has brought for industries, environmental and social issues have also been challenged. In this context, Toman's use of lean production principles along with digital technologies has emerged as a sustainable strategy in order to reduce the negative effects on the environment, society and the challenges facing it. But the important point in between is the importance of social aspects along with technical aspects. The underlying importance of the category of culture as a social aspect in the organization is of great importance for the foundation of these principles. For this reason, in this research, the digitization of production has been investigated on sustainable performance with the mediating role of lean production and moderator of lean culture. The statistical sample consisted of 211 companies active in the value chain of automobiles and related parts, and a standard questionnaire was distributed among them using a simple random method. Smart-PLS3 software was used for analysis. The results of the hypothesis test showed that digitization and lean production have a significant effect on the realization of sustainable performance. Also, by using digital technologies and establishing a pure culture, it is possible to improve the performance of industries and reduce environmental and social impacts.

Abstract

Today, the use of self-healing concretes has attracted the attention of various researchers. In this paper, the effect of Bacillus subtilis bacteria with different concentrations were used for evaluation on concrete containing zeolite.The mentioned bacteria were produced in the laboratory and added to the concrete mixing plan. In order to evaluate the effect of Bacillus subtilis bacteria on specimen with zeolite, resistance and durability tests including compressive strength, ultrasonic, water penetration test and water absorption tests were performed on the specimen at different ages. Also, using scanning electron microscope (SEM) and optical microscope, the self-healing of concrete was evaluated. The results of the compressive strength test showed that the specimen containing zeolite with a concentration of 2.8×108 cells/ml increased the compressive strength by 16.76% and the specimen without zeolite increased the compressive strength by 13.51%. Also, the presence of Bacillus subtilis bacteria in the mixing design led to a 15% decrease in water absorption of specimens without zeolite and 30% of specimens with zeolite. Based on the results of the experiments, the most suitable concentration, for the simultaneous improvement of the resistance parameters and durability among the different concentrations of Bacillus subtilis bacteria, is suggested to be 2.8 x 108.
