Model and algorithm of the conceptual scheme formation for knowledge domain in distance learning

The article describes a knowledge model, oriented to the asynchronous mode of distance learning. The formalization of the knowledge model for a given domain, the operations on the knowledge and the algorithm of the knowledge model creation are submitted. All received decisions can be realized in a program environment compatible with the SCORM standard. The described methodology, based on a generalized knowledge model, enables to develop a distance learning course mainly for the fundamental knowledge. In this paper we describe the methodology and illustrate its use through a project to develop a distance learning course for a queuing system. Moreover, a practical application is proposed based on the eQuality project.

Competence Management in Knowledge-Based Organisation: Case Study Based on Higher Education Organisation

Authors present the method and tools for competency management in knowledge-base organisation. As an example, the higher education organisation working under Open and Distance Learning condition is examined. Competency management allows to management knowledge in the efficient and effective way on the stuffs and students level. Based on the system analysis the management model for educational organisation was created. Next, method for quantitative competence assessment was presented. Moreover, the authors explore possibilities of integrating new competence description standards with existing mathematical methods of competence analysis into one common framework. The product of this idea is the concept of reusable Competence Object Library.

Cost estimation algorithm and decision-making model for curriculum modification in educational organization

The decision about curriculum modification usually takes place at the knowledge level, mainly with consideration of individual academic staff competences and qualifications. However, traditional approaches to cost estimation of curriculum modification are focused on material resources only. In this paper we present a cost estimation method and decision model for curriculum modification in educational organizations. The proposed method works at the knowledge level and employs competence sets as knowledge representation models in educational organizations. Authors used the theory of hierarchical, multilevel systems in order to define the model of the decision-making process of curriculum modification and its dimension. Basing on this and also using a fuzzy competence model the cost estimation algorithm in the form of a group competences expansion algorithm is proposed. The algorithm focuses on the cost of staff competence expansion caused by the knowledge development process.

Extended ontological model for distance learning purpose

In the article authors propose an extended ontological model for distance learning, concerning pedagogical and cognitive requirements of the teaching/learning process as well as environmental requirements represented by SCORM standard. The main characteristic of the dedicated ontological model is reusability, which manifests itself in the possibility of adapting the knowledge model to different contexts and for different users by simply enabling knowledge sharing and knowledge management. Additionally, the article contains case studies (SCORMs course) presenting the proposed model in action.

System for creative distance learning environment development based on competence management

The students creativity comes into action when student produces an outcome or product that is both novel and useful as defined within some learning context. The creative distance learning environment supports students creativity on the social, cognitive and technology levels. In this paper the method for creativity environment development is presented. Based on the competence set theory the creativity level can be measured. Moreover, competence modelling allows to created individually adapting creative tasks and projects as well as creativity supporting knowledge network. The authors propose the model of e-learning information system for competence-based creative space development.

A method of social collaboration and knowledge sharing acceleration for e-learning system: the distance learning network scenario

Nowadays, e-learning systems take the form of the Distance Learning Network (DLN) due to widespread use and accessibility of the Internet and networked e-learning services. The focal point of the DLN performance is efficiency of knowledge processing in asynchronous learning mode and facilitating cooperation between students. In addition, the DLN articulates attention to social aspects of the learning process as well. In this paper, a method for the DLN development is proposed. The main research objectives for the proposed method are the processes of acceleration of social collaboration and knowledge sharing in the DLN. The method introduces knowledge-disposed agents (who represent students in educational scenarios) that form a network of individuals aimed to increase their competence. For every agent the competence expansion process is formulated. Based on that outcome the process of dynamic network formation performed on the social and knowledge levels. The method utilizes formal apparatuses of competence set and network game theories combined with an agent system-based approach.

Motivation Model in Community-Built System

Every person can be characterized by motivation. Therefore, a collective motivation model of users of an information system can be applied for increasing its overall efficiency and productivity. In this chapter, the motivation model for an environment of community-built system is proposed. The model’s objective is to maintain control of social and economic systems. All of the psychological, cognitive, and social aspects of the community-built system have been incorporated into the model. Having introduced an analysis of the networked nature of knowledge, an ontological model for knowledge representation in community-built system is formulated. Following that, the main features of a computer-supported collaboration process are discussed to establish the environment of a community-built system. The motivation model is located within the environment and leverages the qualities of the ontological model.

Approach to practical ontology design for supporting COTS component selection processes

The COTS (Commercial Off-The-Shelf components) selection process is difficult due to the huge number of existing COTS components. Moreover, the price of a mistake is great due to the complex nature of information systems. In this paper an analysis of different COTS component selection methodologies is presented. Based on this, the ontology for supporting COTS component selection processes is proposed. In order to achieve a high level of practicality on different levels of decision making, the ontology is implemented in Protege software.

Intelligent Open Learning Systems

In presented book the Intelligent Open Learning Systems (IOLS) are proposed, described, discussed, and evaluated. The IOLS is a system in which traditional methods of online teaching are enhanced through the use of artificial intelligence and cognitive science. This is the main topic of the book. It consists of ten chapters and is divided into three parts. The first part concentrates on the Open Learning System (OLS) analysis, in particular: the social and educational meanings of the OLS, the new role of the teacher and the new requirements regarding the structure of didactic material. Moreover, the cybernetic model of student, teacher and computer collaboration is presented, the teaching-learning process content and its main characteristics are discussed, and the system based approach to the OLS design is proposed. The second part is focused on the problem of knowledge modeling in the OLS based on the ontology and the competence approaches and leading to the learning object concept and competence management in open systems. The third part describes applications of the OLS in the virtual laboratory for competence transfer, the community-built system of distance learning network, and the AGH student city the real-life application of the OLS concept. The authors research findings presented in the book should be useful in various applications related to knowledge management, e-learning systems and information systems.

Model of community-build system for knowledge development

The community-build system (CBS) is a system for content creation by a community operating on a dedicated engine (e.g. Wiki). The CBS demonstrated how collaborative efforts can be a powerful feature to build a massive knowledge repositories. In the paper the model of community-build system is presented. The model is focused on the knowledge-base content creation process. The editor, creator and the repository are main models actors. Moreover, the proposed CBS model allows to calculate the performance measurements like average number of editors/creators, average on-line editors/creators time. Based on the Markovian Chain theory the dynamic aspect of repository development is analyzed as well. In addition, the presented model is interpreted in the e-learning context.
