English teaching process is the process of"asking"and"answering"between teachers and students. Teachers should not only pay attention to the artistry of questioning, but also attach great importance to the strategy of asking questions. Appropriate teachers' questions are conducive to cultivate students' divergent thinking, and encourage students to better master knowledge by thinking and discussing, thus contributing to classroom interactions move towards a climax.展开更多

The present study aimed to determine the effectiveness of collective education life skills on mental health and resilience of teachers in Zahedan. The population of the study included all teachers at schools with normal students and teachers at schools with exceptional students in Zahedan, among which 60 teachers at normal schools and 20 teachers at exceptional schools were selected and placed in two groups of experimental and control, respectively. Initially, members of the experimental group were taught 10 basic life skills in 10 2-hour sessions. Mental health and resilience questionnaires were distributed and gathered before and after the training sessions. Results indicated the positive effect of life skills training on mental health of teachers at schools with normal students and teachers at schools with exceptional students, which meant that the more the life skills training to teachers at schools with normal students and teachers at schools with exceptional students, the lower their mental health scores would be. Results also indicated the positive effect of life skills training on resilience of teachers at schools with normal students and teachers at schools with exceptional students, which meant that the more the life skills training to teachers at schools with normal students and teachers at schools with exceptional students, the higher their resilience scores would be.展开更多

The symptoms of PTSD are particularly believed to occur predominantly in children. We believe that Yogo teachers, who play a role in maintaining and promoting the health of children, are expected to provide appropriate support for children with a tendency for PTSD. In this study, we investigated the tendency for PTSD in students at University, as well as self-esteem related to depression and anxiety. Furthermore, we clarified the relationship between PTSD and self-esteem and examined the support provided by Yogo teachers. As a result, it was found that the higher the tendency for PTSD, the lower the self-esteem. We believe that the onset of PTSD causes a decline in memory ability and attentional function, which interferes with one’s life and leads to self-denial, resulting in a decline in self-esteem among those with a high tendency for PTSD. These results suggest that Yogo teachers should provide support to prevent the onset of PTSD in child students due to accidents, incidents, natural disasters, etc., as well as support to prevent the decline in self-esteem associated with the onset of PTSD.展开更多

Hence in order to gain a better understanding of the issue in Chinese senior high school context, the present research seeks to examine teachers' and students' attitudes and beliefs with respect to their perceived functions and effects in incorporating L1 in classrooms. In accordance with previous literature, The research indicated positive role of L1, especially in enhancing students' understanding of difficult concepts and creating comfortable learning environment. In addition, it is notable that, in difference from other studies, the National College Entrance Examination has exercised considerable influence on the perceptions of participants.展开更多
