Furthermore, focus on skepticism understand how patients with high levels of may react information differently. Medical is related a patient’s doubts about the value conventional care; therefore, skeptics have...

In this document, we describe the concept and use of KnowledgeMap, an interactive visualization classification tool for exploring communities research in a scientific discipline. We define aggregated measure association between documents, based on their text, references, how they are cited by other documents. This is then used to develop document algorithm web-based tool. demonstrate application Information Systems (IS) discipline analyzing all publications top IS journals during last ten...

Active learning is an instructional model that focuses on shifting the responsibility for to students by increasing engagement.
