Statistical methods have been used to improve processes and accelerate technological development. The aim of this study was to investigate the influence of the variables of heat treatment process of steel wires SAE 51B35 and seek the best condition of certain process parameters adjustment to reduce the depth of decarburization superficial. Four factors were identified as potentially important to the quality of the material. Each of these factors was studied at two levels and all experimental races were held in the production environment. To conduct this survey of classic way would require a large number of experiments, which involve high cost, however, by using the method of design of experiments, structured in a fractional saturated array, it was possible to reduce the financial cost. The study made it possible to conclude what the factors and interactions were causing decarburization problem and what are the best settings to minimize the problem.

The active learning methodologies correspond to a new teaching model built and based on the interaction and participation. In this context, we have the Blended Learning, a methodology that combines online ways of learning, by means of Distance Education and traditional. This study aims to present the contribution of the Communication and Information Technologies (CITs) on the application of active learning methodologies. Therefore, it was carried out a Bibliographic and Documental Research in two Virtual Learning Environment (VLE). The first, from a Higher Education Institute, in Brazil, that uses the Blended Learning, in the Flex modality, in which, some subjects are developed on-site and other, online, by means of a Virtual Learning Environment. On it, it is provided, for the students, the content of the subject online, video classes and exercises. Another Virtual Learning Environment presented is the one from University of Harvard, called Interactive Learning Toolkit (ILT) – created by Professor Eric Mazur and his team, for the development of the Teaching Methodology, called Peer Instruction, containing reading activities and exercises to be done before the lesson by the students. We verified that, in the Higher Education Institutes studied that the CITs have contributed for the knowledge transmission, being a support for the development of active learning methodologies, as in the Peer Instruction case, that uses the data obtained from the online activities to teach, in class, the knowledge in a collaborative way.
