Develop Academic Question Recommender Based on Bayesian Network for Personalizing Student’s Practice

Study in Literatures shows that tracing knowledge state of student is corner stone of intelligent tutoring system for personalized learning. In this paper, an academic question recommender based on Bayesian network is developed for personalizing practice question sequence with tracing mastery level of student on knowledge components. This question recommender is discussed with theoretical analysis, and designed and implemented in software engineering way. It provides instructor with tools for building knowledge component network and setting question of course. It also makes student personalize practice questions of course. This question recommender is planned to deploy in real learning context for the future validation of how well such question recommendation improves performance and saves practice time for student.

Multicultural differences in the public sphere

The present article plays off two conceptions of the public sphere against one another. The first one sees in it a sign of what is already present in the private sphere, whereas the second regards it as a symbol that has to inscribe its own symbolic force into the private realm. That this is by no means a mere academic question becomes obvious by way of several examples analyzed at great length: the institution of mourning and the discussion about the presence of religious symbols in the public sphere. An argument for considering the Muslim veil as a protection against the divine is put forward in an attempt to clarify the presuppositions of our current predisposal against it. Ultimately, pluralism should perhaps not just be taken to refer only to the presence of others outside of us who we are able to numerically count, but might be the more difficult plight of having to cope with an otherness within each of us. Should the latter be the case, then we are in need of a public sphere where we can leave behind and thus honor what is not only differentiating us from others but also from ourselves.

Theoretical and Practical Aspects of Conducting Meetings and Events in Virtual Worlds

Whether businesses will make use of virtual worlds for meetings, training, and events is not just an academic question. Use of existing and newly developed virtual worlds is expected to grow for the near future. International companies are entering a variety of virtual worlds to promote collaboration among their geographically dispersed workforce for training and meetings, as well as for business-to-business and business-to-consumer applications with internal and external audiences. These worlds provide engaging experiences that can be enjoyable and memorable. This article addresses opportunities and challenges in conducting meetings in virtual worlds. It covers the evolution of technology for virtual meetings, a theoretical analysis of technology acceptance, case studies on organizations utilizing virtual worlds, and practical considerations for conducting virtual meetings and events.
