Strategies for Fostering Interaction in Online Classrooms:A Conversation Analysis of Teacher-Student Verbal Interaction in Random Questioning in Pandemic-Initiated Online Teaching

This paper aims to explore how a veteran teacher organizes online teaching initiated by the pandemic and how she deals with the problems in online teacher-student verbal interaction.By analyzing a corpus of 20 audio-recorded online lessons between a math teacher and her students during the COVID-19 pandemic from April 11 to May 10,2022,four interactional segments are selected as the focus of the study.The results of the conversation analysis of the segments showed that students’modesty,lack of confidence,lack of ability,and network delay are the main factors affecting online teacher-student interaction.By encouraging students to answer questions,enlightening students to give answers,enriching students’answers,and entertaining the teaching atmosphere(“4Es”strategies),the teacher solved the problems successfully.The findings from this study can provide pedagogical experience and implications for practical teaching.

A Case Study of Computer-based Teacher-Student Interaction outside Class

This case study examines the interaction through emails between a professor and one of his third-year students outside of the classroom to explore the problems in the teacher-student interaction.It shows that confronted with difficulties,the student turns directly to her teacher,yet failing to make her specific difficulties known,and the teacher spares no pains to exemplify the doing of assignments,yet knowing little about his student’s knowings and unknowings.At the end of the article are some enlightenments:seeking help after self-attempting and helping after knowing.

Optimizing Teacher-Student Collaborative Assessment in the Production-Oriented Approach:A Dialectical Research

Teacher-student collaborative assessment(TSCA)aims to address the challenges of responding to students’work in the Production-Oriented Approach:low efficiency and poor effectiveness.As part of a bigger project carried out in a Chinese university over a period of three years,the present study explored how the teacher prepared and implemented TSCA in class,especially with a focus on how she determined the assessing objective and worked collaboratively with her students in class to achieve it,using the students’written and translated texts as examples.By adopting the dialectical research(DR)method,this paper collected qualitative data such as teaching plans,classroom recordings,and reflective journals of the teacher-researcher(the author),along with students’written drafts and translated texts.TSCA theory and classroom practice have been refined simultaneously by means of putting theory into practice and reflecting upon it.The optimized pre-class and in-class procedures may shed some light on applying TSCA to L2 classrooms.

Zonal Coupling Analysis Method of Seismic Response of Offshore Monopile Wind Turbine

The seismic safety of offshore wind turbines is an important issue that needs to be solved urgently.Based on a unified computing framework,this paper develops a set of seawater-seabed-wind turbine zoning coupling analysis methods.A 5 MW wind turbine and a site analysis model are established,and a seismic wave is selected to analyze the changes in the seismic response of offshore monopile wind turbines under the change of seawater depth,seabed wave velocity and seismic wave incidence angle.The analysis results show that when the seawater increases to a certain depth,the seismic response of the wind turbine increases.The shear wave velocity of the seabed affects the bending moment and displacement at the bottom of the tower.When the angle of incidence increases,the vertical displacement and the acceleration of the top of the tower increase in varying degrees.

Autonomy in Scaffolding as Learning in Teacher-Student Negotiation of Meaning in a University EFL Classroom

Based upon sociocultural theory, this study investigates the dynamics of the teacher＇s roles and learner autonomy in the process of scaffolding in teacher-student negotiation of meaning in an EFL classroom, The participants were 25 undergraduate students and a Chinese teacher of English at a university in China. The teacher-student dialogue was the central mechanism mediating the construction of negotiation of meaning and form in language learning. The analysis of classroom discourse and the teacher＇s retrospection from an interview illustrated the teacher＇s different roles in interaction, where scaffolding acted as a structured pedagogical tool. The study revealed that the learners were afforded assistance to progress from other- regulation to self-regulation, and consequently, the teacher exploited opportunities to enhance learner autonomy in negotiation of spaces for autonomy in classroom teaching. The study has probed into the significance of the teacher＇s capacity of controlling scaffolding effectively and generated implications for teacher development and learner training.

Scaffolding in Teacher-Student Interaction:A Case Study in Two Oral English Classes in China

This paper reports a case study designed to understand classroom interactional processes in a Chinese university. The case study focuses on scaffolding in teacher-student interaction as well as the process of shifting the responsibility from the teacher to student. Our first aim was to determine how teacher-student interactions in two oral English classes were distributed, and our second aim was to determine how the two teachers perceive their roles in teacher-student interaction and how their perceptive differences were reflected in teacher-student interaction in their oral English classes. The data were collected through videotaping and an interview. Results show that distribution patterns of teacher-student interactions were mainly different in the two oral English classes, and the role perception differences of the two teachers were partly reflected in their teacher-student interaction. The study suggests that the process of shifting the responsibility from teacher to student is a complex process which demands great efforts from teachers as well as willingness from students.

Enigma of Exam-oriented Education in China:A comparison on Sino-U.S.Educational Concepts in Higher Education

College English teaching in China has long been criticized for its orientation to examination that consequently brings about negative learning attitude and ineffective learning achievement.Chinese educationists have brought forward several ap proaches to solve this problem but little has been changed due to the cultural influences.This paper analyzes the roots of examoriented education system in China in perspective of culture by comparing the Sino-U.S.cultural elements in depth in tradition al culture,learning and teaching motivation,teacher-student relationship and learners'engagement in class.This paper finally poses two suggestions on how to change the current situation gradually:(1) Focus on the washback of evaluation system on edu cational concepts.(2) Transform the product-evaluation to process-evaluation gradually by standardizing the current evaluation approaches,especially the standards of process-evaluation.

The Role of Relationships with Teachers in Adolescent Development among a National Sample of Chinese Urban Adolescents

A nationally representative sample of 1640 Chinese urban adolescents (mean age=14.5 years) and their parents and teachers were surveyed to examine the associations between relationships with teachers and parents and adolescents' developmental outcomes such as academic performance, psychological well-being, altruistic behaviors, and misconduct. Results showed that the quality of adolescents' relationships with teachers was highly correlated with adolescent outcomes, in most cases more so than for relationships with parents. Furthermore, such associations were the same across both genders and three grade levels. These findings suggest that teachers may play an especially significant role in Chinese adolescent development. This study adds to the small but growing literature on the importance of teachers as well as other non-parental adults in adolescent psychosocial development.

Chinese Teachers’Professional Identity and Beliefs about the Teacher-Student Relationships in an Intercultural Context

This paper presents a qualitative study of immigrant Chinese teachers’professional identity and beliefs about the teacher-student relationship in an intercultural context.Theoretically,this study takes its departure from a sociocultural perspective on understanding professional identity.The empirical analysis in the study drew mainly upon ethnographic interviews with a group of Chinese language teachers in Denmark concerning their life experiences,perceptions,and beliefs.The results of this study suggest that teachers’beliefs about their roles as teachers and about student-teacher relationships are shaped by both their prior experiences and backgrounds and the current social and cultural contexts in which they are situated.Changes of context(e.g.,from China to Denmark)often lead to a transformation of their professional identity and beliefs.Being a teacher in an intercultural context often exposes them to the confrontation of diverse challenges and dilemmas.On one hand,teachers in this study generally experienced a transformation from being a moral role model,subject expert,authority and parental role to being a learning facilitator and culture worker.On the other hand,they developed diverse individualized coping strategies to handle student-teacher interactions and other aspects of teachers’professional identity.

Gao's interacting shear flows( ISF) theory and its inferences and their applications

Gao＇s viscous/in-viscid interacting shear flows （ISF） theory, proposed by professor Gao Zhi in Institute of Mechanics, China Academy of Science, and its inferences and their applications in computational fluid dynamics （CFD） are reviewed and some subjects worthy to be studied are pro- posed in this paper. The flow-field and motion law of ISF, mathematics definition of strong viscous shear layer flow in ISF, ISF equations, wall-surface compatibility criteria （Gao＇s criteria ）, space scale variety law of strong viscous shear layer reveals flow mechanism and local space small scale triggered by strong interaction that cause some abnormal severe local pneumatic heating phenomenon in hypersonic flow. Gao＇s ISF theory was used in near wall flow, free ISF flow simulation and design of computing grids, Gao＇s wall-surface criteria were used to verify calculation reliability and accuracy of near wall flows, ISF theory approximate analytical result of shock waves-boundary layer interac- tion and ISF equations were used to obtain the numerical exact solution of local area flow （ such as stationary point flow）. Some new subjects, such as, improving near-wall turbulent models according to the turbulent flow simulation satisfying the wall-criteria and illustrating relation between grid-con- vergence based on the wall criteria and other convergence tactics, are suggested. The necessity of applying Gao＇s ISF theory and wall criteria is revealed. Difficulties and importance of hypersonic vis- cous/in-viscid interaction phenomenon were also emphasized.
