An increasing number of instructional technologists and scholars seek to develop and propose digital learning platforms for the implementation of constructivist-oriented learning scenarios in introductory programming courses. The combination of Open Sim and Scratch4OS can be a worthwhile innovation for high school students to learn basic programming concepts using a Community of Inquiry (CoI) m...

PASION is an ongoing European funded project whose objective is to provide a framework capable of providing augmented communication services for several multi-user applications. The goal of our work is to give users information based on SNA indices in order to increase the awareness of their social context, their collaboration and social interaction, and to create a sense of social presence at ...

In the example of the Venus statue there are the uncovered or so called original version and the covered or hidden version. Having the two objects, the visible and the covered, we have to acknowledge the fact that it is still an object, no matter of its presentation. These two different presentations of it are then divided into the known and the unknown. The statue covered with a veil raises mo...

This paper studies the reputation and transparency of cooperative movement in Malaysia. Keywords—Cooperative movement, reputation, transparency, web presence.

The authors examined whether the nature of the opponent (computer, friend, or stranger) influences Spatial Presence, emotional responses, and threat and challenge appraisals when playing video games. In a within-subjects design, participants played two different video games against a computer, a friend, and a stranger. In addition to self-report ratings, cardiac interbeat intervals (IBIs) were ...

mg(oh)2 nanoparticles were synthesized by a rapid microwave reaction. the effect of sodium dodecyl sulfonate (sds as anionic surfactant) and cetyl tri-methyl ammonium bromide (ctab as cationic surfactant) on the morphology of magnesium hydroxide nanostructures was investigated. multi wall carbon nano tubes was organo-modified for better dispersion in cellulose acetate matrix. the influence of m...

the electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (mwcnts) is presented. cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (ppo). a redox couple with an anodic and counterpart cathodic peak is obtained. the influence of various parameters such as ph, scan rat...

An increase of asynchronous online discussions in website provides much opportunity for L2 learners from different global communities to be exposed to the target language at their own pace and time. However, no research looking at the essentials of social presence and cognitive presence in creating a supportive learning environment in such a context has been done. This study investigated the pa...

in this paper, a novel compensator based on magnetically controlled reactor with fixed capacitor banks (fc-mcr) is introduced and then power system stability in presence of this compensator is studied using an intelligent control method. the problem of robust fc-mcr-based damping controller design is formulated as a multi-objective optimization problem. the multi-objective problem is concocted ...
