Instrumento de avaliação de processos cognitivos para a aprendizagem de subestações de energia em ambientes 2D e realidade virtual

This study describes the development of a prototype to evaluate the potential of environments based on two-dimensional modeling and virtual reality as power substations learning objects into training environments from a central operation and control of power utility Cemig. Initially, there was an identification modeling features and cognitive processes in 2D and RV, from which it was possible to create frames that serve to guide the preparation of a checklist with assigning a metric weight for measuring cognitive potential learning in the study sites. From these contents twenty-four questions were prepared and each was assigned a weight that was used in the calculation of the metric; the questions were grouped into skill sets and similar cognitive processes called categories. Were then developed two distinct environments: the first, the prototype features an interactive checklist and your individual results. And, second, a system of data management environment for the configuration and editing of the prototype, and the observation and analysis of the survey results. For prototype validation, were invited to access the virtual checklist and answer it, five professionals linked to Cemig's training area. The results confirmed the validity of this instrument application to assess the possible potential of modeling in 2D and RV as learning objects in power substations, as well as provide feedback to developers of virtual environments to improve the system.

Intervenção mediacional na aprendizagem do braille: um estudo com crianças deficientes visuais

This study aimed to construct and evaluate a proposed mediational intervention with preschool children through reading workshops and writing in Braille system. The proposal is based on the concepts of Vygotsky on defectology and approach to the Mediated Learning Experience (MLE) developed by Feuerstein. For the research were drawn up ten Mediational workshops, in which they developed a work by reading a children's story and from her reading activities and writing in Braille system. The workshops took place within in kindergarten room of the institution. Study participants were four blind children, six and seven years in an institution that assists visually impaired people in the city of Uberaba / MG, and their mothers and the teacher responsible for the room in which they study. During the workshops, the children showed interest in participating in the activities of reading and writing in Braille. We believe that the data built during the research are not sufficient to establish a generalization, due to the small number of participants. However, at the end of the workshops and the assessment of participants' responses can infer the relevance of the proposal, because in addition to the interest shown and the request of the children there were more activities like that, it was noticed greater fluency in reading and greater ease in writing.
