A blockchain-based online language learning system

To check students’ daily language learning tasks and give students corresponding reasonable scores based on their daily behavior is hard for teachers. The existing online language learning systems are vulnerable and easy to be modified by teachers or system managers. Blockchain can provide immutable and trusted storage service and automatic calculation service. Therefore, a blockchain-based online language learning system is proposed in this paper to monitor students’ daily study and automatically evaluate their behavior so as to save teachers from tedious and complex homework verification workload and provide trusted and reliable evaluation on students’ behavior. This paper first introduces the current situation of language learning in universities and the related works on blockchain-based online language learning system. Then the system is detailed in its structure and smart contracts. At last, we implement this system and do the analysis and summary.

混合数据的邻域区分度增量式属性约简算法

增量式属性约简是一种针对动态环境下的数据挖掘方法.目前已经提出的增量式属性约简算法仅适用于符号型的信息系统,而很少有对混合信息系统进行相关的研究,这促使在混合信息系统下构建相关的增量式属性约简算法.区分度是用于设计属性约简的一种重要方法,本文将传统的区分度在混合信息系统下进行推广,提出邻域区分度的概念,然后分别研究了邻域区分度在混合信息系统下对象增加和对象减少时的增量式学习,最后根据这种增量式学习分别提出了对应的增量式属性约简算法.UCI数据集上的相关实验结果表明,所提出的增量式属性约简比非增量式属性约简能够更快速的更新约简结果.

Responsivity to Facial and Linguistic Cues

Though information regarding personality and emotional variables are communicated through facial cues, linguistic cues, vocal cues, body position cues, and body movement cues, many individuals are aware of only responding to the linguistic content of others' behavior. Since such a wide variety of cues are available to the expressive individual, contradictory messages will be communicated by most individuals from time to time. The present study investigated the response of judges to incongruent cues. Judges were presented a 46 item test in which they were to rate the affect communicated through an individual's concurrent facial expression and linguistic message. On 32 of these items the face and the words communicated markedly different levels of pleasantness. Groups of 42 and 35 undergraduate students were tested for their tendency to utilize one or the other kind of cue. Data analysis suggested strikingly high reliability in individual's responsivity to facial or linguistic cues (r =.87, .92). Tests of this kind cannot be used to make statements about the general level of the public's responsivity to one kind of cue or another, since the artificial cues can be manipulated to make one or the other cue more or less striking, and the collector of any artificial cues has no way of knowing to what extent his material is representative of communication in the world at large. The reliability of this test, however, allows future research to divide groups into those more or less responsive to facial or linguistic cues.     

Self‐adapting protocol tuning for multi‐hop wireless networks using Q‐learning

Today's network control systems have very limited ability to adapt to changing network conditions. The addition of reinforcement learning‐based network management agents can improve quality of service by reconfiguring the network layer protocol parameters in response to observed network performance conditions. This paper presents a closed‐loop approach to tuning the layer three protocol based upon current and previous network state observations, specifically the Hello Interval and Active Route Timeout parameters of the AODV routing protocol (AODV‐Q). Simulation results demonstrate that the self‐configuration method proposed here demonstrably improves the performance of the original Ad‐Hoc On‐Demand Distance Vector (AODV) protocol, reducing protocol overhead by 43% and end‐to‐end delay 29% while increasing the packet delivery ratio by up to 11%.

Moderating effect of learning styles on a learning management system’s success

This study uses the DeLone and McLean model to determine the moderating impact of learning styles on the success of learning management systems from a student’s point of view. The main objectives of this research are: (1) to evaluate the Delone and McLean model of information system success in the context of learning management systems and, (2) to determine the effect of the learning styles of students on this model. An in-person survey of 258 engineering students was used to evaluate the research model. The analysis is based on structural equation modelling, specifically partial least squares. The results indicate that the research model explains use, user satisfaction, and perceived benefits of a learning management system. In addition, the Felder-Silverman learning styles (sensing-intuitive, visual-verbal; active-reflective; sequential-global) modify the strength of the relationships between the variables of the success model.

Adaptive Learning Objects for t-learning

IDTV (Interactive Digital TV) opens new learning opportunities for those social groups that would hardly have access to traditional forms of education. However, viewers are not usually active learners, for this reason, education through IDTV should be offered in an attractive way, so as they get engaged in the learning experience. For this to be possible, we need to introduce personalization in the t-learning field. To achieve this goal, we present, in this paper, a proposal of self-adaptive t-learning objects, which show a different behavior depending on user's characteristics. These objects are conformant to the ADL SCORM (Sharable Content Object Reference Model) standard for which we propose an extension in order to permit this type of learning objects. We expose as well an authoring tool to these objects, which hides the implementation details to the content creator.     

Engineering Communication An Analytical Method of Teaching Engineers to Communicate

Engineering students , even some who have previously lost interest in English, become enthusiastic learners when they are shown that the ability to communicate precisely is a necessary part of engineering. Accepting this thesis, the Engineering School at Arizona State University in 1955 incorporated an engineering communications course into the core of all degree programs. In the fourteen years the course has been offered, it has been successfully completed by about two thousand students, with an average failure of about three percent. This high percentage of completion is attributed to three things: the communication skills developed are related to the work of engineers; the teaching method is analytical; and the student's work is carefully evaluated by the instructor and revised by the student when not acceptable. The instructor is, of course, another prime factor; a few have been unable to teach the course effectively. In addition to other capabilities, the instructor of this course must be willing to accept the fact that he is teaching the course to make a better engineer-not a journalist, orator, or technical writer. The instructor must also have a firm grasp of English grammar and a certain amount of technology, preferably including prior industrial experience related to the work of engineers.     

“项目驱动+课程设计”教考模式在《数据结构》教学中的应用

项目驱动教学法是师生通过共同实施一个完整的"项目"工作而进行的教学活动,传统的项目驱动教学方法只注重教学过程中的任务驱动和培养学生上课的学习积极性,而"项目驱动+课程设计"的教考模式不但强调课堂教学,而且更加关注学习效果,它先将教学内容打散,按照知识任务模块进行重新整合,再将学生分组,并且针对不同阶段的知识任务组织讨论,最终,以报告的形式上交学习成果,从而完成学习过程。这种教学过程特别适用于应用型院校的学生。文章以计算机专业中的《数据结构》课程教学为例,提供给教师知识任务模块的划分方法,以及帮助教师引导学生在实践中提出问题、分析问题并最终解决问题,从而提高学生学习的积极性和能动性,使学生的理论水平和技能操作达到新的层次。     

The role of affordance in the experience of virtual reality learning: Technological and affective affordances in virtual reality

As virtual reality becomes more and more mainstream, the role of affordances in virtual environments becomes an important question. The goal of this study is to explicate users’ motivational affordances and examine how they influence the acceptance of a virtual reality learning environment (VLE). It examines how motivational affordances in an educational virtual reality (VR) system affect user experience to track and achieve goals for users. A multimixed approach was used by combining qualitative methods and a quantitative survey. First, a critical incident technique was used to explore a range of affordance factors related to VLE. Second, based on the affordance factors identified from the qualitative methods, a survey was conducted to examine the effects of affordance on user cognitive processes and the influence of affordance on the learning process. The results of the user model confirmed the heuristic role of presence and immersion affordance regarding their underlying link to educational affordances, such as empathy and embodied cognition. The findings imply the embodied cognition process of VLE in which technological qualities are shaped by users’ perception and context. The results establish a foundation for VR technologies through a heuristic assessment tool from a user-embodied cognitive process. They confirm the validity and utility of applying affordances to the design of VR as a useful concept and prove that the optimum mix of affordances is crucial to the success of VR design.
