The traditional mode of teaching with lectures, still present in many subjects of the engineering, seems to favor the development of the necessary skills, as active use of knowledge required [ 1 ]. However, they are using simulation games as an educational method in many universities in the world for the advantages they present for learning and the development of various skills, to simulate specific situations of professional activity [2]. This paper presents some background and requirements that games must meet educational purposes and propose their use in subjects related to economics, management and organization of production engineering programs where you can teach and learn from building products with simple items like cardboard paper on the theory of constructionism to build a product where people are building theories and knowledge in the mind [3]. The use of games is not widespread in universities in Argentina, however you can generate more motivating learning situations as it leaves the board becoming less abstract and more concrete learning. Classroom climate changes as students take a more participatory role and the teacher intervenes as a guide or facilitator of learning. This work could motivate teachers and researchers to promote their use in teaching and in future research to evaluate the potential of its use as a learning tool.展开更多

However, previous studies reported a gap between high environmental awareness and behavior. So to promote this practice, it is necessary to clarify the determinants that lead to practice. Because of the rapid economic growth in developing countries, including Vietnam, pollution problems and energy consumption are of major importance. This study aims to propose methods to promote pro-environmental practices based on a questionnaire and statistical analysis that investigated university students in Vietnam＇s Ho Chi Minh city. From the factor analysis, in actions to do with the power-saving behavior of standby power and home electronics, and the use of air conditioning, four evaluation criteria including effectiveness, cost feasibility, convenience, and social norms are extracted. The covariance structure analysis showed that the evaluation of convenience represented the strongest causal relation to a given power-saving action, and the action, in turn, can lead to improvements in most practical activities so as to enhance their convenience. Finally, several methods to save energy are proposed based on the results of the questionnaire.展开更多
