Managing evolution and change in web-based teaching and learning environments

The state of the art in information technology and educational technologies is evolving constantly. Courses taught are subject to constant change from organisational and subject-specific reasons. Evolution and change affect educators and developers of computer-based teaching and learning environments alike – both often being unprepared to respond effectively. A large number of educational systems are designed and developed without change and evolution in mind. We will present our approach to the design and maintenance of these systems in rapidly evolving environments and illustrate the consequences of evolution and change for these systems and for the educators and developers responsible for their implementation and deployment. We discuss various factors of change, illustrated by a Web-based virtual course, with the objective of raising an awareness of this issue of evolution and change in computer-supported teaching and learning environments. This discussion leads towards the establishment of a development and management framework for teaching and learning systems

VRLAB: an interactive 3D learning environment

The recent information and networks explosion has greatly affected the fields of education and distance learning, leading to the development of educational material that provides support for interactive communication between trainers and learners. Web technology in particular stands as a medium with great educational value, mainly due to its ability to grant access to training material without any spatial or temporal constraints, thus motivating and attracting new users to experience this novel form of learning. As the Internet constantly evolves, new technologies tend to influence the domains of e-learning. The combination of the Web, multimedia and 3D graphics has resulted to the implementation of new training tools bearing advanced navigational and interactive functionalities along with appealing user interfaces that encourage learners to actively participate in the learning process. Moreover, 3D Virtual Worlds have surfaced making available new forms of visualization, distribution and presentation of training material. The objectives of the present paper are to discuss the educational value of 3D virtual worlds and the emerging challenges regarding the analysis, design and development of these innovative user interfaces. VRLAB is an e-learning system created solely to address the aforementioned issues. It offers a three dimensional multimedia user interface with extended interactivity, permitting learners to participate virtually in studying and performing simulated lab experiments for a course in Computer Graphics

USAge of Groupware in Software Engineering Education at the Cscw Laboratory of University Duisburg-essen: Possibilities and Limitations

This paper analyzes the application level in CSCW laboratory there are Electronic meeting rooms, Video Conferencing, Desktop Conference (Passenger), and BSCW system which conducting in The University Duisburg – Essen Germany. This analysis included short analysis and discussion about possibilities and limitation of each experiment followed by outlook how this lab can be further developed.Multi-user to Multipoint Videoconferences is introduced to cover all of devices join to the conferences. A computer network, PSTN (Public Switched Telephone Network), ISDN Phone, Wireless Infrastructures (accessed by laptop, smart phone, PDA) and videoconferences systems is proposed to be integrate

SOCR: Statistics Online Computational Resource

The need for hands-on computer laboratory experience in undergraduate and graduate statistics education has been firmly established in the past decade. As a result a number of attempts have been undertaken to develop novel approaches for problem-driven statistical thinking, data analysis and result interpretation. In this paper we describe an integrated educational web-based framework for: interactive distribution modeling, virtual online probability experimentation, statistical data analysis, visualization and integration. Following years of experience in statistical teaching at all college levels using established licensed statistical software packages, like STATA, S-PLUS, R, SPSS, SAS, Systat, etc., we have attempted to engineer a new statistics education environment, the Statistics Online Computational Resource (SOCR). This resource performs many of the standard types of statistical analysis, much like other classical tools. In addition, it is designed in a plug-in object-oriented architecture and is completely platform independent, web-based, interactive, extensible and secure. Over the past 4 years we have tested, fine-tuned and reanalyzed the SOCR framework in many of our undergraduate and graduate probability and statistics courses and have evidence that SOCR resources build student's intuition and enhance their learning.

Developing Online Learning Materials for Higher Education: An Overview of Current Issues

The changing roles and challenges for higher education and the increased productivity required of faculty are driving forces for the development of more diverse and efficient teaching methods. Educational trends are toward more learner-centered materials. In response to these trends, colleges and universities are now offering courses at a distance and in forms other than traditional delivery. Online courseware materials may be a viable means of fulfilling these numerous requirements but are very resource-intensive to develop. Multiple approaches to developing online learning have been tried, with limited success. The primary approach has been for faculty to enter their own course materials into the computer. To maximize university resources, the most effective approach for developing online learning materials must be determined and institutionalized. While faculty are the most logical persons to provide course content and design, faculty should not be expected to complete the technical tasks associated with developing online learning materials
