Estudio de caso en México: los alumnos de ingeniería civil opinan sobre las debilidades de egreso Carlos Arcudia Abad Rómel G. Solís Carcaño Ingeniería alumnos profesores empleadores ingeniería civil investigación educativa Esta investigación aborda el problema de la percepción que los estudiantes de ingeniería civil tienen de laprofesión al momento de concluir sus estudios. La metodología utilizada se basa en un enfoque cualitativo yexploratorio sobre lo que ellos consideran sus debilidades de egreso de la universidad. Su percepción se comple-menta y contrasta con opiniones vertidas por profesores y empleadores que interrelacionan con los alumnosdurante su formación y su inicio en la práctica profesional. Los resultados mostraron que, de acuerdo con su cortaexperiencia, los alumnos poseen una visión estrecha de, la profesión. Como complemento, también, se exploróla opinión de los estudiantes respecto a sus debilidades de ingreso a la universidad, y a los contenidos delcurrículo que consideraron de poca utilidad y de alta dificultad 2004 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64324204 es http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.2 Vol.24
