Renovation of Teacher's Role in Action Research

under the present educational reform backgrounds,college English teachers are expected to re-examine their role,shift their mind-sets from the traditional passive position of acceptors of educational theory to creator of their own local teaching theories.

Teacher's Role in the Oral English Class

English speaking has been paid more attention today, especially in the age of globalization. Teachers are attempting to find out more effective methods to enhance the teaching results of English speaking. Facing the great demands and present difficulties of oral English classes, teachers have to conduct more study and practice to find out what roles that an oral English teacher has to take in the oral English classroom. Compared with the traditional teaching role in the English classroom, an oral English teacher has to fulfill more than one role in the classroom teaching so as to provide better learning conditions for students. Lacking more exposure to the real interaction with native speakers, students expect the oral English teacher to be a creator of the language environment. With various teaching and learning activities in the oral English classroom, the teacher has to be a good organizer to ensure every student to achieve improvement. An oral English teacher also has to correct students'language errors while ensuring the smooth progress of the classroom teaching. Only when an oral English teacher make clear what roles he or she has to take in the classroom can he or she achieve effective teaching.

The Teacher's Role and Teaching Procedures in the Teaching of Oral English

English teachers in China are aware that what kind of English teaching method should be employed to improve student 's linguistic acquisition and that communicative competence becomes more and more important.In English teaching,teachers always make it possible for students to be more often in contacts with the English language,thus creating an atmosphere of learning English language.Help students to jump over the gap between only reading English loudly and speaking English fluently.Here I will show the importance of the teachers ' role in English teaching and their applies in oral English teaching.

Teacher's Roles in Making Harmonious Class

The present study will focus on teacher's roles, while providing a description of the current "state of the art," as regards the difficulties and problems encountered. In other words, an attempt will be made to trace some of the intrinsic factors that, either positively or negatively, affect teaching and learning habits, with a view to fostering a holistic approach to education and forging constructive, interpersonal relationships in the classroom which can facilitate the educational process.

Discussion on Teacher's Role under Life Threatening Circumstances

This paper first reviewed a controversial case in which a teacher ran away from his students in a earthquake. Several educational ethnic questions were aroused from the case: Is protecting students part of teacher's job? To what extent should it be applied? etc. Then the author aims to answer these questions based on a real case study from philosophical perspective, that is, analyzing teacher's role(i) as a human being;(ii) as a educator;(iii) as a educatee. Finally the paper concludes that teachers should protect their students even under life threatening circumstances.

On the Learner Autonomy and the Teacher's Role

About learning,more emphasis was put on the role of teachers in the past,while gradually people realized the key role of the learner during the process of teaching and learning.The traditional class mode was challenged.The concept of student-centre class changes the roles of the teacher and the students.The rule of the students becomes more and more important,which means the student will take more responsibilities on learning,and their autonomy should be firmed.And this article will discuss the teacher's role under the concept of learner autonomy.

Teacher's Role in Students'Group Work in College English Classroom

A Comparison Between the Teacher's Role in the Task-based Language Teaching and that in the Traditional Language Teaching

This paper talks about the different teacher's role between traditional language teaching and task-based language teaching. Atthe beginning we will compare the teacher's role in terms of language theory and language teaching theory. The traditional teaching ob-jective is teaching the grammar. The teacher is the guider of the grammar. In the new English curriculum syllabus, the teaching objectiveis to train students' communicative competence. The teacher is the organizer of the teaching. In the traditional language teaching proce-dure, the teacher is authority and dictator. In the task-based approach, the teacher is equal to the students. In the traditional languageteaching activities, the teaching activities are boring; the teacher is the leader of the class. In the task-based approach, the teacher is thearranger of the task also they are the helpers and cooperators of completing the task.

Teacher's Role in Intercultural Language Education

Role Dynamic Allocation of Human-Robot Cooperation Based on Reinforcement Learning in an Installation of Curtain Wall

A real-time adaptive roles allocation method based on reinforcement learning is proposed to improve humanrobot cooperation performance for a curtain wall installation task.This method breaks the traditional idea that the robot is regarded as the follower or only adjusts the leader and the follower in cooperation.In this paper,a self-learning method is proposed which can dynamically adapt and continuously adjust the initiative weight of the robot according to the change of the task.Firstly,the physical human-robot cooperation model,including the role factor is built.Then,a reinforcement learningmodel that can adjust the role factor in real time is established,and a reward and actionmodel is designed.The role factor can be adjusted continuously according to the comprehensive performance of the human-robot interaction force and the robot’s Jerk during the repeated installation.Finally,the roles adjustment rule established above continuously improves the comprehensive performance.Experiments of the dynamic roles allocation and the effect of the performance weighting coefficient on the result have been verified.The results show that the proposed method can realize the role adaptation and achieve the dual optimization goal of reducing the sum of the cooperator force and the robot’s Jerk.

Understanding the roles of Brønsted/Lewis acid sites on manganese oxide-zeolite hybrid catalysts for low-temperature NH_(3)-SCR

Although metal oxide-zeolite hybrid materials have long been known to achieve enhanced catalytic activity and selectivity in NO_(x)removal reactions through the inter-particle diffusion of intermediate species,their subsequent reaction mechanism on acid sites is still unclear and requires investigation.In this study,the distribution of Brønsted/Lewis acid sites in the hybrid materials was precisely adjusted by introducing potassium ions,which not only selectively bind to Brønsted acid sites but also potentially affect the formation and diffusion of activated NO species.Systematic in situ diffuse reflectance infrared Fourier transform spectroscopy analyses coupled with selective catalytic reduction of NO_(x)with NH_(3)(NH_(3)-SCR)reaction demonstrate that the Lewis acid sites over MnO_(x)are more active for NO reduction but have lower selectivity to N_(2)than Brønsted acids sites.Brønsted acid sites primarily produce N_(2),whereas Lewis acid sites primarily produce N_(2)O,contributing to unfavorable N_(2)selectivity.The Brønsted acid sites present in Y zeolite,which are stronger than those on MnO_(x),accelerate the NH_(3)-SCR reaction in which the nitrite/nitrate species diffused from the MnO_(x)particles rapidly convert into the N_(2).Therefore,it is important to design the catalyst so that the activated NO species formed in MnO_(x)diffuse to and are selectively decomposed on the Brønsted acid sites of H-Y zeolite rather than that of MnO_(x)particle.For the physically mixed H-MnO_(x)+H-Y sample,the abundant Brønsted/Lewis acid sites in H-MnO_(x)give rise to significant consumption of activated NO species before their inter-particle diffusion,thereby hindering the enhancement of the synergistic effects.Furthermore,we found that the intercalated K+in K-MnO_(x)has an unexpected favorable role in the NO reduction rate,probably owing to faster diffusion of the activated NO species on K-MnO_(x)than H-MnO_(x).This study will help to design promising metal oxide-zeolite hybrid catalysts by identifying the role of the acid sites in two different constituents.

The Influence of Academic Self-Efficacy on Learning Engagement in Online Education in China:The Mediating Role of Effort

The shift towards online intelligent learning has become the norm in education and is now a fundamental part of modern educational activities.However,this new model can influence students’learning behavior and lead to changes in their approach to learning.Based on online intelligent learning,we investigated how the academic self-efficacy of nursing students affects their engagement with learning and explored the role of academic attribution as a mediator.Five hundred fifty-three nursing college students from Hebei and Hunan provinces in China participated in the online questionnaire.The results revealed that effort plays a mediating role in the relationship between academic self-efficacy and learning engagement.

Associations between residence and cognitive function among Chinese older adults: the mediating role of leisure activity

Background:Cognitive function is a current research hotspot,residence may be related to differences in cognitive function,and the mediating role of leisure activities are limited in Chinese research.This study used leisure activities as a mediating variable to investigate the mediating role of leisure activity between place of residence(city-town-rural)and cognitive function among Chinese older,this is where the innovation of the article comes in.Methods:Using cross-sectional data from the 2018 Chinese Longitudinal Healthy Longevity Survey,Pearson correlation analyses were employed to examine the relationships among various indicators.Mediation analyses were conducted using the SPSS PROCESS macro program,version 3.5,written by Hayes,to explore the mediating effects of leisure activity between place of residence and cognitive function in older adults.Results:A total of 10955 older adults were included in this study,with a mean age of(84.23±11.57)years.Among them,2739(24.8%)lived in the city,3627(33.1%)in town,and 4615(42.1%)in rural areas;their leisure activity score was(5.34±3.77),and their cognitive function score was(24.69±6.65).Place of residence,leisure activities,and cognitive function were significantly correlated(P<0.01).Using city as a reference,place of residence is negatively associated with cognitive function,and place of residence not only had a direct effect on cognitive function in older adults:town-cognitive function(effect=–0.399;95%confidence interval(CI)=(–0.685,–0.113));rural-cognitive function(effect=–0.42;95%CI=(–0.698,–0.141)).There were also indirect effects on cognitive function through the pathway of leisure activity:town-leisure activity-cognitive function(effect=–0.17;95%CI=(–0.246,–0.1)),rural-leisure activity-cognitive function(effect=–0.199;95%CI=(–0.272,–0.13)).Conclusion:Leisure activities play a partially mediating role between the impact of place of residence and cognitive function in Chinese older adults,and it is vital to pay attention to the impact of place of residence on the cognitive function of older adults in various aspects,and to increase the participation rate of older adults in leisure activities,which is beneficial to the prevention of cognitive decline and the protection of older adult’s physical and mental health.
