2. Intelligent tutoring system for distance education
This study aims to develop and implement a tool called intelligent tutoring system in an online course to help a formative evaluation in order to improve student learning. According to Bloom et al. (1971,117) formative evaluation is a systematic evaluation to improve the process of teaching and learning. The intelligent tutoring system may provide a timely a

3. Environmentally responsive polymeric "intelligent" materials: the ideal components of non-mechanical valves that control flow in microfluidic systems
Miniaturization and commercialization of integrated microfluidic systems has had great success with the development of a wide variety of techniques in microfabrication, since they allowed their construction at a low cost and by following simple step-series procedures. However, one of the major challenges in the design of microfluidic systems is to achieve co

5. Celine: um modelo para utilização e adaptação de conteúdo scorm em ambientes inteligentes de aprendizagem
The effort to maintain contents in ILE (Intelligent Learning Environments) was the inspiration behind the development of this work. It was observed that the contents to be taught are heavily reliant on these environments, which makes their sharing with other systems difficult. In addition, these materials are created with internal tools, which offer few reso

7. Proposta de utilização do vitrocerâmico anortita como um sistema de liberação de fármacos
Anortita glass-ceramic is a biocompatible material that shows intelligent material properties, since its degradation occurs depending on pH variation. This characteristic is particularly interesting when regarding clinical applications in which the material should start degradation when in contact with biological fluids, like in temporary implants. The use o

11. âProject management knowledge learning environment: Ambiente inteligente de aprendizado para educaÃÃo em gerenciamento de projetosâ
Currently, Distance Education (DE) can be seen as a reply to some ever-increasing demands: fast dissemination of knowledge, with low cost and accessibility; qualification, both academic as well as corporative; and life-long learning. However, DE environments have often not reached their potential, because they only present their contents in a very impersonal
