In a computer supported learning environment both in the synchronous and asynchronous mode, interaction is a prerequisite to facilitate learning. Hence to facilitate effective interaction, a good working team of learners and instructors is important. For this to happen, social presence is necessary to create sound social interaction for instructional effectiveness. Social presence is the abilit...

This paper reports on a theory-based empirical investigation of cultural considerations in the appropriation of affordances and on the development of technological intersubjectivity in a computer supported collaborative learning environment. Socio-technical affordances are “action-taking possibilities” and “meaning-making opportunities” in a sociotechnical system relative to the capabilities of...

The Coronavirus pandemic has thrown public schooling into crisis, trying to juggle shifting instructional modes: classrooms, online, home-schooling, student pods, hybrid and blends of these. This poses an urgent need redesign curriculum using available technology implement approaches that incorporate the findings learning sciences, including emphasis on collaborative learning, computer mediatio...

In today economic environment, innovation is considered the primary source of competitive advantage for companies. The advent of Web 2.0 tools has provided organizations with new models and tools to improve collaboration and co-creation of new knowledge assets. In particular, the shift to Open Innovation models has been recognized as a major change in the way companies create and manage innovat...

In response to calls in the Information Systems literature to contextualize usage, we propose that measuring computer-based multitasking is essential to accurately describe and properly assess the manner in which people use Information Technology. To this end, we develop several multitasking metrics ranging from a very lean dichotomous variable to a very rich measure that combines user, task an...

Due to the different losses caused by various photovoltaic (PV) array faults, accurate diagnosis of fault types is becoming increasingly important. Compared with a single one, multiple PV stations collect sufficient samples, but their data not allowed be shared directly due potential conflicts interest. Therefore, federated learning can exploited train collaborative model. However, modeling eff...

Stochastic model checking is a recent extension of traditional model-checking techniques for the integrated analysis of both qualitative and quantitative system properties. In this paper we show how stochastic model checking can be conveniently used to address a number of usability concerns that involve quantitative aspects of a user interface for the industrial groupware system thinkteam. thin...
