The success of teachers in professional environments has a desirable influence on their mental condition.Simply said,teachers’professional success plays a crucial role in improving their mental health.Due to the invaluable role of professional success in teachers’mental health,personal and professional variables helping teachers succeed in their profession need to be uncovered.While the role of teachers’personal qualities has been well researched,the function of professional variables has remained unknown.To address the existing gap,the current investigation measured the role of two professional variables,namely job satisfaction and loving pedagogy,in Chinese EFL teachers’professional success.To do this,three validated scales were provided to 1591 Chinese EFL teachers.Participants’answers to the questionnaires were analyzed using the Spearman correlation test and structural equation modeling.The data analysis demonstrated a strong,positive link between the variables.Moreover,loving pedagogy was found to be the positive,strong predictor of Chinese EFL teachers’job satisfaction and professional success.The findings of the current inquiry may help educational administrators enhance their instructors’professional success,which in turn promotes their mental and psychological conditions at work. 展开更多

The COVID-19 pandemic caused significant disruptions in the field of education worldwide,including in the United Arab Emirates.Teachers and students had to adapt to remote learning and virtual classrooms,leading to various challenges in maintaining educational standards.The sudden transition to remote teaching could have a negative impact on students’reading abilities,especially in the Arabic language.To gain insight into the unique challenges encountered by Arabic language teachers in the UAE,a survey was conducted to explore their assessment of teaching quality,student-teacher interaction,and learning outcomes amidst the COVID-19 pandemic.The results of the survey revealed a significant decline of student reading abilities and identified several major issues in online Arabic language teaching.These issues included limited interaction between students and teachers,challenges in monitoring students’class participation and performance,and challenges in effectively assessing students’reading skills.The results also demonstrated some other challenges faced by Arabic language teachers,including a lack of preparedness,a lack of subscription to relevant platforms,and a lack of resources for online learning.Several solutions to these challenges are proposed,including reevaluating the balance between depth and breadth in the curriculum,integrating language skills into the curriculum more effectively,providing more comprehensive teacher professional development,implementing student grouping strategies,utilizing retired and expert teachers in specific content areas,allocating time for interventions,and improving support from both teachers and parents to ensure the quality of online learning. 展开更多

It is increasingly common to find alarming news related to tragic events occurring in schools around the world.Being able to deal with these situations without getting hurt is a task not suitable for everyone.In general,teachers are the ones who must deal with this type of situation in addition to other daily problems that appear in any classroom that make the level of stress to which they are subjected can become dangerous.This research aims to know the current situation of teachers in a region of southeastern Spain in terms of their level of work stress,resilience,and other associated variables,for which an ex post facto quantitative approach study was designed.For this purpose,an ad hoc sociodemographic questionnaire,and questions based on the Teaching and Learning International Survey of the Organization for Economic Co-Operation and Development,the Maslach Burnout Inventory,and the Brief Resilient Coping Scale were applied.The participating sample consisted of 470 teachers.The main findings were that 6%of teachers had burnout(high emotional exhaustion,high cynicism,and low professional effectiveness simultaneously).Resilience correlated inversely with stress,emotional exhaustion,cynicism,excessive teaching,and difficulty maintaining classroom discipline.In conclusion,knowing the needs of teachers allows us to reflect on what kind of prevention and intervention programs are necessary to improve the well-being of teachers and thus improve the quality of education. 展开更多

Studies in second language teacher cognition(SLTC)of pronunciation teachers have increased in the last 10 years,due mainly to the fact that the decisions teachers make about explicit instruction are critical for the development of second language(L2)pronunciation in learners.Although recent research has indicated that nonnative-speaking teachers(NNSTs)can be as effective as native-speaking teachers(NSTs)in pronunciation instruction,and that their training needs resemble those of NSTs,the way NNSTs implement L2 pronunciation instruction has not been studied extensively.This is important to understand given the number of NNsTs of English worldwide at present,and because of the potential benefits of nonnative-speaking pronunciation teaching models in general.In this study,I analysed the way an experienced NNST implemented explicit pronunciation instruction in a context of English as a foreign language(EFL)to understand both his actual teaching practices and the rationale behind such practices.Using a framework of knowledge base of language teaching,this study demonstrates how factors such as previous teaching and learning experiences,teaching context,and L2 learner characteristics shaped and guided the techniques the teacher implemented in class.These results are discussed in terms of implications for pronunciation teaching and teacher training purposes. 展开更多
