The aim of this work is to explicitly describe the process implemented during teaching and learning through a didactic characterized by investigation, the permanent accompaniment and the participative dialogue with students of the first semester of the Systems Engineering Program, repeaters of the Subject Introduction to Engineering of Systems. The idea is approaching students to experience a blended learning methodology supported by the Smile Platform and achieve the generation of concepts during the construction of essential questions derived from these contents. The experience is methodologically framed by the Action Participation Research, a qualitative-quantitative study in which statistics are used to recognize the changes in the elaboration of questions. Students are able to exercise higher order thinking skills from managing of information, analyzing and thinking with information and constructing questions and answers using Smile. The highest level of critical thinking was achieved in the evaluation of the questions elaborated by classmates. [ABSTRACT FROM AUTHOR]

This paper analyzes the vehicular mobility in 3 specific points of the municipalities of Riohacha and Maicao, La Guajira Colombia. Variables of vehicular flow such as queue arrival times, density, permanence, infractions and other implicit ones were used. Observation and description processes are carried out over four continuous months in critical hours; the flow variables that affected the selected points, causes and effects were identified and described, which are represented using influence diagrams. The whole process was simulated, using high performance software such as PTV Vissim 8 and Vensim PLE. It is recognized that the vehicular mobility in the studied points, the congested genres due to the high frequency of vehicles that transit and that the current traffic regulations are something that don't help enough to improve the flow. In addition to infractions, accidents and situations of intolerance, toxicity is generated in the environment by the emission of CO2 by vehicles waiting at each critical point, matters to which authorities still do not pay attention.

An analysis is presented on the socioeconomic conditions of the Wayuu indigenous community of Manzana, located in the municipality of Manaure, department of La Guajira, Colombia. The study was done from the Social Engineering concept, considered as the possibility that engineering student could visualize real life, not only from numerical data but also approaching such a reality. The methodology used in this research is qualitative-quantitative, in which statistics is used to record data, to count, to select and to categorize aspects that allow understanding and explaining reality. The qualitative aspects are collected from direct observation, description and graphic representation. All this allows contrasting the reality that perceived their senses and the statistical results. A survey was applied to 484 households in the community. One of the factors that stop development of the community is the limited understanding between the interaction of technological and social problems and the appropriation of reality. Students were able to recognize the value of context analysis beyond only numerical results. [ABSTRACT FROM AUTHOR]

In this work a training process implemented in an ethnic education institution in an indigenous community in marginal conditions is described. The study follows a qualitative and quantitative methodology to develop the descriptive model. Computer graphics is employed to build influence diagrams and Forrester's diagrams. These diagrams allow graphically capturing the essence of this complex system and help to understand these relationships between variables of the training process. System dynamics makes visible the influence of independent variables that affect the educational process such as geographical location, date of teacher recruitment and transportation of children to school.
