In distance education, the elementary function of data management system is to handle the related data in network teaching in filtering, sorting and classification, and make it to be the useful information for management and decision-making. Through the analysis and comparison of the commonly used data management modes that mainly used for calculating the learners' learning information in network...
Iterative and incremental development (IID) is a staple of multiple software development methods, including Spiral development, Unified process and Agile development. However, a number of papers warn of possible pitfalls in application of this approach in examples of real-life development project. In this paper we will describe an (in our opinion) successful application of IID to a software project...
In database design, the attributes and their functional dependencies are abstracted from the software requirements specification (SRS) by the forward engineering process. The abstracted attributes from a forward engineering process are structured depending on the functional requirements. Then, the database relations are composed, by the related attributes and their functional dependencies, based on...
This paper presents a method leveraging the ubiquity of the mobile phone as an input device for immediate feedback and assessment of structured presentation delivery and learning. Human interactions within established workflow processes of collaborative sessions can be defined, allowing feedback and assessment tasks to take place in most meaningful moments. Data collected at these moments have a context...
QuantX is an interactive tool that is dedicated to helping students learn how to formulate complex query conditions that require complex universal and existential quantification. Preliminary evaluation results of the tool are encouraging.
In order to increase education scope and explore new teaching models, while network teaching is deeply investigated, the implementation model, method and technologies are researched. Therefore, the web-based network teaching platform is designed and developed. The platform creates a network teaching environment which is extended from traditional classroom teaching and tries to feed back to classroom...
The article analyzes the web page, multimedia and database technologies basing on giving a minute description of four modules of the network course of database principle: course learning, exercise and test, teaching assistant and system management. Finally, it sums up the characteristics and applications of the network courses.
Delivering learning and education is the most invaluable building block in today's knowledge-based society. The emergence of learning objects in learning technology has had a big impact on the learning environment and its community. Teachers and students have more facilities for using the e-learning system, which has made the learning process more effective. This paper presents development of learning...
There is a permanent need for planning and analysis of existing networks, provisioning of new demands, installing new components in the network, and study possible networking options. To fulfill all these requirements, a flexible design tool is needed, that is based on a flexible network model. FLEXPLANET, the presented modeling, design and analysis tool makes it possible to consider real size operating...
