CSCL is based on the idea that computer applications can scaffold and implement advanced socio-cognitive processes for knowledge sharing and knowledge building. But do we really understand these processes that are supposed to be implemented? This paper will focus on the "epistemological infrastructure" of CSCL. We will analyze three models of innovative knowledge communities in order to better ...

In present scenario various tools like firewalls, anti-virus tool, network security tools, malware removal tools, monitoring tools etc, are being used for providing security to computer systems. Computer security tools available in present era need to be updated and monitored regularly. If any computer users do not regularly update the security tools, such systems will be vulnerable to virus an...

In this paper I focus on data taken from two different graduate seminars at the University of Arizona in which the classroom activities and curriculum have been meaningfully supported by the use of a computer-mediated learning environment. I analyze transcripts from postings made throughout both of the courses and relate this data to dynamic systems theory. I argue that the data supports the su...

The research describes a methodology for applying designand management-based scaffolding techniques aimed to enhance cooperative behaviour. Based on assumptions of how successful online learning groups act together we developed feedback-based mechanisms that aimed at contributing to group functions of well-being, member support, and productive learning outcomes. The collaborative online learnin...

the main issues in any society are teaching and learning and main elements of this story are the teacher and the learner. there are different psychology schools in which any of them in turn, have taken many extensive researches about behavior, and facts and theories of learning have been studied from a particular perspective. rationalism asserts that the human intellect has the highest energy a...

Because of changes in the field of computer science, the context and content of computer science education at school is continuously evolving. But new topics alone do not lead to concrete and suitable courses. Too often, demands of the practice obscure the underlying theory. Learning theories, didactical knowledge and computer science itself should be heeded in educational practice and the desi...

The Essen Learning Model is a generic development model supporting development processes on three levels: development of curricula, learning sequences, and learning units. We focus on finding an adequate combination of didactical methods and educational technologies. Secondly, we focus on interoperability, reusability, and ease of use, using standards on the modeling level (ARIS), architecture ...

The emergence of computer-mediated worldwide networks or virtual campus has been very important in the last years, not only in the social communication, but also in the educational field. Is precisely in learning processes where we have based our research. There are many advantages that virtual campus offers in learning processes and according to (Méndez, Rivas and del Toro, 2007) a very import...

This paper presents a Learning Analytics approach for understanding the learning behavior of students while interacting with Technology Enhanced Learning tools. In this work we show that it is possible to gain insight into the learning processes of students from their interaction data. We base our study on data collected through six laboratory sessions where first-year students of Computer Engi...

convictions are strong that multimedia courseware holds great promise for enhancing learning efficiency among learners. this study thus aimed at comparing the effects of the multimedia programs introducing 100 vocabulary items through pictures and streaming video with those of teacher instruction on increasing efl learners’ vocabulary repertoire. a total of 120 subjects were identified as inter...
