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.

Video,Internet and Metaverse:The Media Transitions of Interaction in Theatre

The integration of theatre art with media such as video,the Internet and metaverse embodies intermediality and shows interactivity characteristics.Video is the first to open the possibility of interaction between performers and stage space in the theatre,thus greatly expanding the relationship between people and video in the links of environment,atmosphere,narrative,action and conflict,making stage performance more flexible and changeable.The rapid rise of computer technology represented by the Internet provides two interactive modes of node structure and natural language for digital theatre performance,opening the path for the audience to participate in theatre interaction.The metaverse media environment represented by video games and virtual reality has dramatically changed the freedom of audience participation in theatre.“Digital embodiment”enables the audience to immerse themselves in virtual theatre performance and become a part of theatre composition,thus bringing unprecedented performance experience.

An Analysis on Teacher-student Role Changing in Interactive Teaching Mode

Teachers and students play important roles in teaching activity,and they are the most essential parts of the system.The relationship between teachers and students,the core schooling interpersonal relationship,directly determines whether the teach ing activities can go smoothly or not,and is an important index to measure the quality of teachers and students'school life,and also is an important factor that affects the social function of education.For a long time,relationship between teachers and students has been a hot topic in education and in different sectors of the society.This dissertation aims at discussing the teacher-student role changing in interactive teaching mode to provide reference for building a harmonious relationship between teachers and stu dents.

An Empirical Study on Interaction in EFL Classrooms in Middle Schools in Western Areas of China

Interaction in EFL （English as a foreign language） classrooms has received much attention in recent years However, little research exists that has investigated interaction in Chinese EFL classrooms. To bridge this gap, the current research investigates interaction in EFL classrooms in middle schools in China in terms of： （1） the amount of teacher talk and interaction; （2） the type of teacher questions and teacher feedbacks; and （3） the amount and forms of meaning negotiation. The data set include observation records and observation reports of 140 naturally occurring lessons in middle schools in China. The findings reveal that there is not much interaction in EFL lessons in middle schools in western areas of China, which is shown by class time dominated by TTT （teacher talking time）, teacher questions and feedbacks that do not encourage students＇ responses and very little negotiation of meaning Possible causes are analyzed, and implications of this research for EFL teaching in China, teacher development and further research are also discussed

Mobile Communication Voice Enhancement Under Convolutional Neural Networks and the Internet of Things

This study aims to reduce the interference of ambient noise in mobile communication,improve the accuracy and authenticity of information transmitted by sound,and guarantee the accuracy of voice information deliv-ered by mobile communication.First,the principles and techniques of speech enhancement are analyzed,and a fast lateral recursive least square method(FLRLS method)is adopted to process sound data.Then,the convolutional neural networks(CNNs)-based noise recognition CNN(NR-CNN)algorithm and speech enhancement model are proposed.Finally,related experiments are designed to verify the performance of the proposed algorithm and model.The experimental results show that the noise classification accuracy of the NR-CNN noise recognition algorithm is higher than 99.82%,and the recall rate and F1 value are also higher than 99.92.The proposed sound enhance-ment model can effectively enhance the original sound in the case of noise interference.After the CNN is incorporated,the average value of all noisy sound perception quality evaluation system values is improved by over 21%compared with that of the traditional noise reduction method.The proposed algorithm can adapt to a variety of voice environments and can simultaneously enhance and reduce noise processing on a variety of different types of voice signals,and the processing effect is better than that of traditional sound enhancement models.In addition,the sound distortion index of the proposed speech enhancement model is inferior to that of the control group,indicating that the addition of the CNN neural network is less likely to cause sound signal distortion in various sound environments and shows superior robustness.In summary,the proposed CNN-based speech enhancement model shows significant sound enhancement effects,stable performance,and strong adapt-ability.This study provides a reference and basis for research applying neural networks in speech enhancement.

工业互联网平台赋能、价值共创与制造企业服务化绩效研究

基于共生理论的“互联网+”企业创新生态系统关系治理模式研究

促进“互联网+”企业创新生态系统可持续发展要求妥善处理好系统中的关系风险。目前“互联网+”企业创新生态系统的相关研究在关系治理、主体互动关系及其可能产生的关系风险和治理机制等方面仍不足。为此,基于共生理论,通过对现有文献的梳理汇总,探讨“互联网+”企业创新生态系统3种关系治理模式的互动方式、关系风险和治理机制,并以小米(小米科技有限责任公司)、抖音、微信小程序等典型案例分析验证。研究发现:偏利共生型关系治理模式下,机构型创新主体为主导者,以效率为导向,实现创新行为的控制,其治理机制为核心企业控治;寄利共享型关系治理模式下,社群型创新主体为主导者,以公平为导向,实现创新关系的扩散,其治理机制为“社群自治+核心企业同治”;互利共赢型关系治理模式下,创新主体间平等合作,以民主为导向,实现创新效能质的提升,其治理机制为社群与核心企业共治。此外,这3种关系治理模式均以技术和创意等资源作为生态系统战略利益的根本来源,并借助其向创新主体表达自己的价值导向。然而,不同的关系特征会引起不同的共生风险,主要包括创新资源投入不平衡、主体利益分配不公平、竞合关系维持不稳定。基于此,要明确“互联网+”企业创新生态系统中主体的角色,核心企业应根据情况选择不同的关系治理范式。

媒介发展背景下收视注意力变化及其对电视剧创作的影响

媒介发展为大众传播带来巨大变化,影响了收视方式,也影响了观众对电视剧的注意力投入。从传统媒体时代到移动互联网时代,观众的注意力呈现出与收视氛围、收视状态变化相对应的特征变化——投入程度变深,投入时间缩短。观众的注意力从更换率低的、长时间的、无互动性的内容转移到更换频繁的、短时间的、有互动性的、社交式的内容上。在此情境下,电视剧创作必然呈现符合观众与媒介间注意力法则的新趋势——内容长度缩短,情节强度增强,以及对互动性进行一系列探索。

电商客服对话提示信息的双任务操作注意分配研究

目的 为研究双任务操作下,不同类型对话提示信息对电商客服注意分配的影响.方法 选取视觉呈现位置和三种常见提示音为自变量,设计了三种实验情景:只呈现两种位置差异的视觉信息、只呈现三种不同的听觉信息、同时呈现视听觉组合信息,对被试人员操作过程中的反应时及正确率进行了分析.结果 电商客服人员在同时接收视听觉对话提示信息时,存在注意分配,视觉上更偏向左侧,听觉上更偏向于机械提示音,当位于左侧的视觉对话提示信息与钢琴音同时出现时,电商客服的操作表现优于其他组合的视听觉对话提示信息.结论 研究对话提示信息双任务操作的注意分配,为电商企业提升客服注意力培训、设计对话提示信息具有一定指导意义.

互联网使用与南方稻农耕地质量保护技术采纳--信息搜寻和社会互动的双重视角

近年来极端气候事件频发和国际局势剧烈变化,加剧了我国人地矛盾对国家粮食安全的挑战,加强耕地保护迫在眉睫。而互联网信息技术快速普及成为推进耕地质量保护技术采纳的重要途径。基于有限理性假设和社会互动理论,揭示互联网使用对农户的耕地质量保护技术采纳并不是“万能药”:农户的在线农业信息搜寻显著促进了耕地质量保护技术采纳,但是在线社会互动削弱了在线农业信息搜寻的积极效应;且由于存在“回声室效应”,如果稻农是“非意见领袖”,则上述削弱作用更加明显。本研究为数字农业农村发展中的保护性农业生产技术的应用推广提供了启示。一方面政府应不断强化农村数字基础设施建设并优化农业技术信息的网络治理,以继续促进农户“自下而上”的农业信息获取对技术采纳的积极作用;另一方面,保护性技术的采纳是“科学性”和“本地性”相融合的过程,应进一步鼓励农技研发的本地化并提高农户的数字素养增强其数字信息甄别能力,以克服互联网和社会网络双重互动对技术采纳带来的消极影响。

青少年电子产品使用行为异化测评、检出率及干预建议——超越成瘾病理学模式的新视角

成瘾病理学模式的电子产品使用行为现有研究既不利于青少年心理健康发展,也未能解决青少年在使用电子产品时造成的社会功能损伤这个关键问题,其研究结果呈现碎片化趋势。从适应和发展的角度,提出“电子产品使用行为异化”这个概念并阐述其鉴别的理论框架,编制《青少年电子产品使用行为异化量表》,对512名中学生进行问卷调查。结果发现,青少年电子产品使用行为异化是一个包括妨碍睡眠的异化、妨碍工作(或学习)的异化、妨碍线下社交的异化的三因子结构模型;《青少年电子产品使用行为异化量表》具有良好的信效度,其测评性能相比网络成瘾诊断更具有全面和精准的优势;青少年电子产品使用行为的总体异化、妨碍睡眠的异化、妨碍工作(或学习)的异化和妨碍线下社交的异化的检出率依次为9.8%、7.2%、6.8%和1.6%。因此,促进良好睡眠和工作(或学习)功能的达成是当前青少年电子产品使用行为异化干预的重点所在。
