There are a number of internet-based models of learning in use by educationalists. Pedagogical approaches vary. Some reflect a traditional distance learning approach whilst others have been developed to embrace the use of Web 2.0 and build on the potential offered by state of the art technological tools. The exponential growth of the use of social networks and online communities offers the potential...
Recently there has been an increasing interest in exploring P2P technologies for developing groupware tools to support online learning activity. Among the many features that make P2P technology an important alternative to develop online learning systems is its fully decentralized nature as well as the possibility to customize the learning environments to the needs of groups of learners. In fact, in...
Clone detection is usually applied in the context of detecting small-to medium scale fragments of duplicated code in large software systems. In this paper, we address the problem of clone detection applied to plagiarism detection in the context of source code assignments done by computer science students. Plagiarism detection comes with a distinct set of constraints to usual clone detection approaches,...
Technology mediated groups interact in surprising ways to produce coherent behavior that contributes to collective and individual ends. Traces of these activities are captured in system log data. In this report we use Erickson's application of human social intelligence to social computing as a frame for contrasting 3 studies of rich trace data captured from an online learning management system. First,...
Evolution of learning processes is almost always linked to social changes and/or technological changes. One of those processes is eLearning, which is involved in the changes brought about by trends 2.0. This new tendencies consider the user, socialization and collaboration as the main important elements and this must be considered also in eLearning contexts. But today learning environments do not...
Web-based learning is now becoming an important learning form in the application of Internet,. The many problems have been brought in the web-based learning process to the researchers and educators. In the learning processes, the learning achievements and the learning evaluation will be important, and then these could effectively promote the learning capacity of students. In this paper, the suitable...
The complexity of web applications becomes a big problem, when applications are growing. Especially if new algorithms should be tested and compared, it is important to be able to separate the newly implemented functions from the core system. It is not enough to use standard frameworks to handle this, but to plan a maintainable structure for the application. This paper describes how a maintainable...
In order to solve the problems in process-oriented writing class of English major and promote students' autonomy in the course learning, a corpus-based teaching mode is proposed in present paper. It analyzes the roles of corpus in English teaching and learning and designs a new type of writing class arrangement, which can nicely apply advanced technology of modern corpus into the process of writing...
Based on the recognition of context for physics teaching in current middle schools, this paper reports a web-based virtual lab (IWVL) for junior high schools' physics experimental teaching. The theoretical foundations for system design, system architecture, functional characteristics, experimental platforms, and four usage scenarios of IWVL are highlighted in the discussions.
A learning process is substantially a knowledge management process. Computers can play multiple roles in human learning and facilitated human learning processes by providing technical, cognitive, and social support. This paper discusses knowledge management in computer-supported learning, explores the knowledge management process in learning process, and suggests how to better support knowledge management...
An agent-oriented pervasive system supporting a context-aware and personalized mLearning services provision within an InfoStation-based University network is presented. The InfoStation's middleware architecture facilitating the users' mobile (WiFi) access to services is described. The agents' interaction is explained in detail. An extended system architecture supporting the service personalization...
Agent technology is a good approach for solving a number of problems concerned with personalized learning. In personal learning contexts individual students are given an environment that takes into account of their needs, interests and aspirations, and this is intended to lead to an enhanced learning experience. The aim of this paper is to show how agent systems can not only form a good framework...
The e-learning system might remove the limitation of learning time and space and offer more learning opportunities. Knowledge-based virtual communities formed in e-learning platform are collaborative groups developed for creating new knowledge. However, it is difficult to choose and introduce the appropriate virtual community, owing to characteristics of intrinsic ambiguity and lack of evaluating...
This paper presents a novel Semantic-Based Conversational Agent (CA) and its application to benefit students with debt who might otherwise face serious consequences, not only financially, but psychologically. The novel semantic-based CA interprets scripts consisting of natural language sentences by means of a sentence similarity measure. User input is measured semantically against the content of the...
Ontologies represent a method of sharing and reusing knowledge on the semantic web. A fuzzy ontology is an extension of domain ontologies for solving the problems of uncertainty. This paper shows how a Fuzzy Ontology based approach can represent user profiles in e-learning environments. The ontological representation of the user profile enhances the performance in tasks such as filtering and information...
In developing countries, mobile devices can play an important role in delivering learning. But, poor information infrastructure and higher costs of mobile devices and connectivity restrict possibilities of providing successful mobile learning services. In the field of Information Communication for Development (ICT4D), this research aims to highlight the possible role of previously unexplored open...
In this paper we present a general framework to describe a trace-based learner modelling process. This framework includes three knowledge models: the first model is an explicit representation of observations about learner's interactions with a TEL-system, the second model describes the structure and elements describing the Learner Model and the last model describes the main knowledge elements types...
Data mining techniques have been applied to educational research in various ways. Given a large sample of learning logs, it is common for sequential mining to return a large number of patterns, only a portion of which are educationally meaningful. In this paper, we proposed a constraint-based pattern filtering method to help researchers discover meaningful, interpretable, and relevant patterns by...
Student model is an essential component in any adaptive learning environment. Various student modelling approaches have been suggested in the literature that focus on learners' competencies, preferences and other personal attributes. However, there is a lack of a comprehensive student model that combines various aspects of student modelling while also considering the aspects of location and context...
In an enterprise context, competencies are often dispersed across different teams. A specific need within the enterprise could not be satisfied only because of a lack of awareness about real competencies owned by employees. The aforementioned problem involves two main critical aspects: the difficulty to manage employees' competencies in order to constantly keep them up-to-date and the ability to agilely...
