Virtual experiment by creating virtual experiment laboratory instruments and laboratory scene to simulate the real experiment, is a process through a computer interface operation of virtual instruments and systems, and to complete the experiment. This paper first analyzes the specific content of human-computer interaction in virtual experiments design. Then put forward five principles on human-computer...
The key of the virtual experiment system for Microcomputer Principle and Interface Technology, a representative of the virtual programmable experiment systems, is to solve the problem of dynamic interaction between the experimental programs and the virtual devices, and it demands high real-time performance. According to the functional needs of the virtual experiment system for Microcomputer Principle...
Due to the problem that students can't get teacher's guide timely in virtual experiment, we have designed the tutor model based on virtual experiment and implemented an intelligent tutor module with rules engine technology, according to the habits of thought when students perform experiments. This module could provide instructional message to students during experiment process. It extends the knowledge...
Due to many foreign language learners do not have speaking enough practice opportunities, we have designed spoken pronunciation training software based on speech recognition technology. This voice recognition software module can score the spoken words based on the pronunciation of each user. It solve the difficult problem of spoken language training. In this paper, we will detail the specific design...
Open Laboratory Management System provides an open virtual experiment environment for students, so that its system performance immediately impacts the quality of students learning. According to analyze the performance requirements of Open Laboratory Management System, the author discovers performance testing points, implements automated performance testing for performance testing points of the system...
As it is very highly difficult and challenging to design one flexible and reusable object-oriented software system, the use of design patterns becomes much more necessary. In this paper, we will present how to design the device management, command system and network protocol, three major parts of a Computer Network Virtual Lab System by using design patterns like Factory Method pattern, Singleton...
Post internship is an important practice step during combining work with study and during running school-enterprise cooperation schools in higher vocational colleges, which has contributed greatly to the development of talents with high skills. This paper is concerned about the lack of the flexibility and the independency when students applying for posts in the current arrangement of post internship...
As one of the most hot debated applications of Artificial Intelligence (AI), case-based reasoning (CBR) provides a methodology by reusing stored knowledge into new solutions. Due to its linear storage structure and similarity computation method between the target problem and the stored case, traditional CBR confronts with great challenges in efficiency and flexibility. In this paper, we propose a...
With its rapid development during recent years, the virtual reality (VR) technology has uncovered a new way to distance education - virtual experiment (VE). Traditional virtual experiment solutions confront with either the lack of scientific management or the difficulties in further extensions. In this paper, we develop an OpenLab platform with virtual experiment learning system to provide a comprehensive...
Due to its outstanding contributions in overcoming the device limitations in traditional experiment process, as well as improving the practice and operation capacity of students, virtual experiment has become an indispensable part of E-learning, and has been widely applied during recent years. As one of the supportive components of virtual experiment, marking system provides an open platform for virtual...
With the development of Rich Internet Applications (RIAs) in recent years, the RIA technology is now widely deployed for user interface. But large amounts of conventional RIAs have close-coupled modules and not very well structure. They will become a great barrier for large scaled applications. In this paper we present an approach to transform conventional RIAs to structured well RIAs which are based...
Electronic commerce (E-commerce) logistics has become one of the most hot-debated issues with the boom of modern information technologies. Different models have been introduced during the recent years. In this paper, a reversed stackelberg approach to E-commerce logistics market based on the supernetwork theory is proposed. In such a hierarchical market model, we take into account the profits, risks,...
This paper designs and implements an individualized multimedia e-learning platform, multi systems based on one platform are published for various learning groups such as primary and middle school students, college students, or students of adult education. It based on J2EE and adopts the popular open source architectures SSH (struts, spring and hibernate). The philosophy of the question and test driven...
