O uso de rob?tica em sala de aula levanta uma quest?o: como os alunos ser?o avaliados nos conceitos que envolvem a aula de rob?tica educacional? Desenvolvemos neste trabalho uma metodologia de avalia??o dos alunos em aulas de rob?tica educacional. Baseado em pesquisas com professores e no conhecimento da equipe sobre a ?rea, levantamos crit?rios de avalia??o relevantes para esta ?rea de ensino, considerando os t?picos de uma aula de rob?tica educacional que devem ser avaliados: montagem do rob?, programa??o do rob? e resolu??o da atividade interdisciplinar proposta. Al?m destes crit?rios, existem pontos sobre rela??o social que tamb?m s?o relevantes em aulas de rob?tica educacional, como intera??o social, trabalho em equipe, concentra??o, criatividade, participa??o, entre outros. Com este objetivo, definimos seis crit?rios avaliativos que podem ser aplicados na avalia??o a crit?rio do professor. No entanto, reconhecemos o desafio da aplica??o de uma metodologia avaliativa em aulas de rob?tica educacional, por demandar muito tempo e esfor?o do professor, que deve ficar atento a todos os passos da aula de rob?tica, e aplicar os crit?rios avaliativos a todos os alunos. Com o objetivo de auxiliar o docente nesta tarefa, inserimos esta metodologia de avalia??o em um simulador de rob?tica educacional, permitindo que o simulador realize a avalia??o de forma autom?tica, fornecendo ao professor apenas os resultados da mesma. O professor ainda ? o respons?vel por definir todos os crit?rios avaliativos, mas o simulador ? o respons?vel por analisar o aluno ? medida que ele executa uma atividade e atribuir a ele notas considerando os crit?rios definidos pelo professor. Por fim, para validar a metodologia de avalia??o, foram realizados testes com professores de rob?tica, nos quais os professores deveriam cadastrar os par?metros avaliativos de algumas atividades e analisar os resultados fornecidos pelo simulador ? medida que os alunos executavam estas atividades. Os resultados mostram que os professores tem interesse em utilizar esta metodologia e que acreditam que os crit?rios avaliativos propostos s?o de grande import?ncia para uma aula de rob?tica educacional, permitindo que o professor realize modifica??es no processo de ensino caso identifique dificuldades por parte dos alunos. / The process of teaching educational robotics involves not only the creation of a robot, but also the use of it for conducting an interdisciplinary activity. The use of robotics in the classroom raises an issue: how will students be evaluated in the concepts that involves educational robotics topics? We developed a methodology used to evaluate students on educational robotics classes. Based on researches with robotics teachers and the knowledge of this research team about the area, we raised evaluation criterias relevant to this area of education, considering the topics of an educational robotics class that should be evaluated: robot assembly, robot programming and the resolution of the interdisciplinary proposed activity. In addition to these criteria, there are points about social relationships that are also relevant in educational robotics classes, such as social interaction, teamwork, concentration, creativity, participation, among others. With this objective, we defined six evaluation criteria that can be applied in the evaluation at the teacher?s discretion. However, we recognize the challenge of applying an evaluative methodology in educational robotics classes, because it requires a lot of time and e?ort from the teacher, who must be attentive to all the steps of the robotics class, and apply the evaluation criteria to all students. With the objective of assisting the teacher in this task, we inserted this evaluation methodology in an educational robotic simulator, allowing the simulator to perform the evaluation automatically, providing the teacher with the results. The teacher is still responsible for defining all the evaluative criteria, but the simulator is responsible for analyzing the student as he performs an activity and assigning grades to the student considering the criteria defined by the teacher. Finally, to validate the evaluative methodology, tests were performed with robotic teachers, in which teachers should register the evaluative parameters of some activities and analyze the results provided by the simulator as the students performed these activities. The results show that teachers are interested in using this methodology and believe that the proposed evaluation criteria are of great importance for an educational robotics class, allowing the teacher to carry out changes in the teaching process if it identifies difficulties by students.

Moreover, the production flows can vary a lot, depending on the charaeteristies of eaeh reservoir. Thus being, the meters used in field for the flow and BSW (water in the oil) measurement must work well in wide bands of operation. For the evaluation of the operation of these meters, in the different operation conditions, a Laboratory will be built in UFRN, that has for objective to evaluate in an automatic way the processes of flow and BSW petroleum measurement, considering different operation conditions. The good acting of these meters is fundamental for the accuracy of the measures of the volumes of production liquid and rude of petroleum. For the measurement of this production, the petroleum companies use meters that should indicate the values with tha largast possible accuracy and to respect a series of conditions and minimum requirements, estabelished by the united Entrance ANP/INMETRO 19106/2000. The laboratory of Evafuation of the Processes of Measurement of Flow and BSW to be built will possess an oil tank basically, a tank of water, besides a mixer, a tank auditor, a tank for separation and a tank of residues for discard of fluids, fundamental for the evaluation of the flow metars and BSW. The whole process will be automated through the use of a Programmable Logicat Controller (CLP) and of a supervisory system.This laboratory besides allowing the evaluation of flow meters and BSW used by petroleum companies, it will make possible the development of researches related to the automation.
