Performance Evaluation of an MCT-Based Peer-to-Peer Architecture

Performance Evaluation of an MCT-Based Peer-to-Peer Architecture

a distributed hash table (DHT) based algorithm, then search efficiency will be hard to improve, because two physically nearby peers may be allocated positions far apart in the MCT hierarchy. To solve this problem, we use ping response time to estimate network distance such that peers in proximity will not waste time going through a long search path to exchange information with each other just because they have been unwittingly allocated too far apart. Furthermore, we propose a binary search method for a requester to locate the potential provider of files of interest; a search time is thus achieved. We compare the performance of the proposed MCT-based P2P network with two other previously proposed P2P architectures, the Chord and the Grapes. Simulation results show that the proposed system not only has shorter average delay and lower jitter for packet transfer, but also has fewer packet losses and higher throughput. These results also indicate the potential of the MCT topology to be the foundation of a P2P network that is both efficient and reliable.

The Design and the Formative Evaluation of a Web-Based Course

The Design and the Formative Evaluation of a Web-Based Course

E-mail: sonia_lu@email.asetest.com.tw ABSTRACT Simulation output analysis has received little attention comparing to modeling and programming in real-world simulation applications. This is further evidenced by our observation that students and beginners acquire neither adequate details of knowledge nor relevant experience of simulation output analysis in traditional classroom learning. With the advances in the Internet learning environment, web-based computer-based training (CBT) can efficiently and effectively enhance the traditional classroom learning. This research addresses the issue of designing a web-based CBT course to assist the classroom instruction in helping students learn better simulation problem solving. The goal is to provide an effective way to learn the implicit experience of simulation output analysis via an efficient interactive environment. A prototype asynchronous web CBT system with simulation analysis guidelines was built to verify our design through a three-stage formative usability evaluation. The results showed that the simulation analysis guidelines organized by this research significantly improved the test scores and the interactive CBT system maintained students’ interests longer than the written format.

Application of a Web-based System to Screen for Hidden Depressive Patients

Application of a Web-based System to Screen for Hidden Depressive Patients

Abstract and Objective Although depression has been regarded as a major public health problem, many individuals with depression still remain undetected or untreated. The Internet may help to detect the hidden depressive patients. The study used the Internet-based Self-assessment Program for Depression (ISP-D) for people to freely screen depressive disorder online. The results showed that 73.9% of 1656 participants had some kind of depressive disorders and 56.2% of them never sought for pro- fessional help. We concluded that Web-based tools could help screen the hidden depressive disorders for whom could assess the Internet.

The implementation and evaluation of a mobile self- and peer-assessment system

The implementation and evaluation of a mobile self- and peer-assessment system

a b s t r a c t Recently, more and more researchers have been exploring uses of mobile technology that support new instructional strategies. Based on research findings related to peer and self assessment, this study devel- oped a Mobile Assessment Participation System (MAPS) using Personal Digital Assistants (PDAs) as the platform. In addition, the study proposes an implementation model of the MAPS that should facilitate the effectiveness of self- and peer-assessment in classrooms. The researcher argues that teachers and stu- dents can benefit from MAPS in various regards including more flexible assessment arrangement, more efficient use of time, and more opportunities for student reflection on learning and assessment. Thirty- seven students taking teacher-education courses with the researcher participated in this study, and these students employed the MAPS to conduct two-round assessment activities that would help these students assess both their own and one another’s final projects. Both the students’ valid responses in a survey herein and scores obtained from the assessment activities confirmed the benefits of the MAPS and its implementation model. Yet, the students voiced such concerns as the objectivity of peer-assessment and the difficulty of providing constructive feedback, and the correlation analysis indicated a lack of con- sistency between teacher-grading and student-grading.

A Study of Document-based MVC Design Pattern for Improve Web-based Application System Development

A Study of Document-based MVC Design Pattern for Improve Web-based Application System Development

As mentioned above, using Façade design pattern reduces the dependency between Controller and Model. However, we must make sure that all the parameters will be integrated at the same time. When Controller transmits a job to Façade, Controller will already gathered all the parameters before it can pass the job to Façade. Such as Fiqure 2, The FaçadeMethod() must transfer parameters to satisfy corresponding methods. In order to simplify the usage of Façade design pattern to reduce the dependency relation between Controller and Model, we can achieve this goal by taking advantage of the characteristics of the Web-based application. That is, to make use of the Request and Response object that be transmitted on the HTTP protocol between client and server. In DMVC, Flow Controller can pass the Request object to Dispatch Controller. When Dispatch Controller needed to call Model objects, there is enough

Design and Evaluation of a Two-Tier Peer-to-Peer Traffic Information System

Design and Evaluation of a Two-Tier Peer-to-Peer Traffic Information System

A BSTRACT Decentralized traffic information systems real- ize real-time traffic information services without the need for a server infrastructure. However, existing systems rely on either the vehicular ad hoc network or application-layer peer-to-peer protocols over a broadband wireless network suf- fering from low lookup success rate, high lookup latency, and maintenance overhead of the P2P network. This article proposes a two-tier VANET/P2P architecture that exploits both VANET and P2P technology. In the low tier, vehicles form a VANET via intervehicle commu- nication to exchange traffic information. On top of the VANET, a portion of the vehicles further establish a P2P overlay through a broadband wireless infrastructure to mitigate the disconnec- tivity problems of the VANET. Simulation results demonstrate that the two-tier architecture can sig- nificantly improve the lookup success rate com- pared to the single-tier VANET systems while reducing lookup latency and maintenance over- head compared to the single-tier P2P systems.

Web-based peer review: The learner as both adapter and reviewer

Web-based peer review: The learner as both adapter and reviewer

3) Metacognition: The teacher and a teaching assistant to- gether read each reviewer’s comments to see who and in which round a student demonstrates higher level thinking. The au- thors looked for qualitative evidence of several cognitive and metacognitive strategies, i.e., critical thinking, planning, mon- itoring, and regulation. Critical thinking refers to students’ ap- propriate reasoning, questioning, and critical evaluation, when receiving new information or applying previous knowledge to new situations. Planning refers to a student’s goal setting, task analysis, and retrieval of prior knowledge in the initial stage of a project. Monitoring refers to track attention while learning, self-testing, and questioning about the learning progress. Reg- ulation refers to the fine-tuning and continuous adjustment of cognitive activities. A review comment containing keywords from any of these four kinds of higher level thinking was coded into an adequate category.

Peer supports on the Web for activating the zone of proximal development

Peer supports on the Web for activating the zone of proximal development

Although students can attain higher levels of thinking or skills if they are scaffolded by experts, such learning systems cannot mediate and include proper students in peer support activities that activate a student’s Zone of Proximal Development (ZPD). Students must actively seek answers to their learning problems in the public discussion forum to attain higher levels of thinking or skills . This study presents a decision tree methodology for activating students’ ZPD by providing peer support in a web based learning system. The experience of and guidelines for utilizing the decision tree methodology for peer support are depicted by a group problem-solving example. Meanwhile, students’ conversation dialogue and the communication network of peer supports during the group problem-solving activity are explored. The proposed methodology allows teachers to go online and use the data collected to efficiently analyze the effectiveness of peer help in activating ZPD.

SCORM-Compatible Learning Management System Based on Peer to Peer Infrastructure

SCORM-Compatible Learning Management System Based on Peer to Peer Infrastructure

access concurrently. In this situation, if the server can not support the load, the quality of the learning environment is reduced and the learner’s learning desire is negatively affected. Hence, this paper proposes a SCORM-compatible LMS based on the Peer to Peer (P2P) infrastructure. In this paper, a currently very popular P2P application, BitTorrent [6][7][8][9], is used to distribute the learning content to a large number of learners. The features of the proposed LMS based on P2P infrastructure are as follows: (1) A SCORM-compatible scalable LMS is provided. (2) Since the transferring task of learning content are distributed over more than one of the learners instead of a central LMS, the transferring speed of learning content is improved. (3) The reading learning content is downloaded and saved in learner site by P2P technology in advance. Hence, the reading performance of learning content is independent of the network bandwidth. (4) The file size of the learning content affects the delivery time of the learning content, such as a multimedia file which size can be more than 100 M byte to 1 G byte per file. In the proposed LMS, since the delivery time of the learning content is independent of the network bandwidth, the file type of learning content can be developed vary diversely.

Application of online annotations to develop a web-based Error Correction Practice System for English writing instruction

Application of online annotations to develop a web-based Error Correction Practice System for English writing instruction

The error correction tools of the Annotation Editor can also be compared with the “New Comment” tool in Microsoft Word. When using the “New Comment” tool to proofread a paper, the user first highlights the area where he/she would like to create a note, and Word adds a balloon linking to that text where the user can add his/her notes. Then the user can use the “Track Changes ” tool to keep track of the changes made to a document. If there is stored information about changes made to the document, the user can choose to display those changes or to hide them. In fact, the “Track Changes” tool in Microsoft Word can be compared with the Viewer in the current system. However, the current system provided students with more learning support for corrective feedback activities than the tools in Word. For instance, the Error Analyzer of the system analyzed students' errors to display the statistical results of error distributions. The error distributions of each writing practice for an individual student could help the student realize the most severe barrier he/she faces in writing. The error distributions for a group of students could also help the teacher realize the unclear concepts most students have in writing so he/she can adjust the instructional strategies. The system indeed offers new ways of gathering corrective feedback and peer feedback infor- mation from students.

Mining Formative Evaluation Rules Using Web-Based Learning Portfolios for Web-Based Learning Systems

Mining Formative Evaluation Rules Using Web-Based Learning Portfolios for Web-Based Learning Systems

Institute of Learning Technology, National Hualien University of Education, Hualien 970, Taiwan, R.O.C. rank@enjust.com ABSTRACT Learning performance assessment aims to evaluate what knowledge learners have acquired from teaching activities. Objective technical measures of learning performance are difficult to develop, but are extremely important for both teachers and learners. Learning performance assessment using learning portfolios or web server log data is becoming an essential research issue in web-based learning, owing to the rapid growth of e-learning systems and real application in teaching scenes. The traditional summative evaluation by performing examinations or feedback forms is usually employed to evaluate the learning performance for both the traditional classroom learning and the web-based learning. However, summative evaluation only considers final learning outcomes without considering learning processes of learners. This study presents a learning performance assessment scheme by combining four computational intelligence theories, i.e., the proposed refined K-means algorithm, the neuro-fuzzy classifier, the proposed feature reduction scheme, and fuzzy inference, to identify the learning performance assessment rules using the web-based learning portfolios of an individual learner. Experimental results indicate that the evaluation results of the proposed scheme are very close to those of summative assessment results of grade levels. In other words, this scheme can help teachers to assess individual learners precisely utilizing only the learning portfolios in a web-based learning environment. Additionally, teachers can devote themselves to teaching and designing courseware since they save a lot of time in evaluating learning. This idea can be beneficially applied to immediately examine the learning progress of learners, and to perform interactively control learning for e- learning systems. More significantly, teachers could understand the factors influencing learning performance in a web-based learning environment according to the obtained interpretable learning performance assessment rules.

interfaces, and function operations found in business, academic, and institutional studies in different countries. The broadness of these resources ensures that the developed criteria in this study can be universally applied. Ninety-seven items were selected and combined into the initial design indicators. Then, this study employed the Delphi technique and standardized scale compilation procedure to screen and revise these indicators. During the five rounds of revision, the revised data were gathered prior to Delphi technique application to ensure expert agreement before the next round. The main tasks in each round were as follows: (1) for the first round: integrating similar indicators and revising the denomination, order, and wording to prevent subjective or inducible content; (2) for the second round: reaching consensus for disagreements or ambiguous viewpoints and deciding the order of indicators; (3) for the third round: continuing to delete, add, or change the debatable indicators and wording as well as the order of indicators; (4) for the fourth round: continuing to revise the indicators;

Web-based peer assessment: feedback for students with various thinking-styles

Methodology Subjects and tasks Subjects were 58 computer science majors (43 juniors and 15 seniors, 18 females and 40 males.) enrolled in a mandatory ‘Operating Systems’ course at a Taiwanese university. Eight topics were covered over an 18-week period, i.e. Introduction, Processes, Memory management, File Systems, Input and Output, Deadlocks, Case Study 1: UNIX, and Case Study 2: MS-DOS. The peer assessment task required students to select a topic regarding the process and memory management of some operating systems and, then, to write an exploratory reading summary. For example, a student compared distributed techniques, such as ODP, CORBA and DCE, in terms of functionality, application areas and advantage/weakness. Another student discussed why microprocessors cost less and perform better than mainframes.
