Evaluating the Complementarity of Communication Tools for Learning Platforms

Title: Evaluating the Complementarity of Communication Tools for Learning Platforms

Venue: CSEDU 2018

Due to the constant innovations in communications tools, several educational institutions are continually evaluating the adoption of new communication tools (NCT) for their adopted learning platforms (LP). Notably, many educational institutions are interested in checking if NCT is bringing benefits in their teaching and learning process. We can state an important problem that tackles this interest as for how to identify when NCT is providing a significantly different complementary communication flow concerning the current communication tools (CCT) provided at LP. This paper presents the Mixed Graph Framework (MGF) to address the problem of measuring the complementarity of an NCT in the scenario where some CCT is already established. Since we are interested in the methodological process, we evaluated MGF using synthetic data. Our experiments observed that the MGF was able to identify whether an NCT produces significant changes in the overall communications of an LP according to some centrality measures.

I am a Professor of the Computer Science Department of the Federal Center for Technological Education of Rio de Janeiro (CEFET / RJ) since 2010. I hold a PhD in Systems Engineering and Computer Science at COPPE / UFRJ. Between 2000 and 2007 I worked in the Information Technology (IT) field where I acquired extensive experience in workflows and project management. I have solid background in the Databases and my primary interest is Data Science. He currently studies space-time series, parallel and distributed processing, and data preprocessing methods. I am a member of the IEEE, ACM, INNS, and SBC. Throughout my career I have been presenting consistent number of published articles and projects approved by the funding agencies, such as CNPq and FAPERJ. I am also reviewer of several international journals, such as VLDB Journal, IEEE Transactions on Service Computing and The Journal of Systems and Software. Currently, I am heading the Post-Graduate Program in Computer Science (PPCIC) of CEFET / RJ.
