Análisis de la Deserción Estudiantil en el Programa Ingeniería de Alimentos de la Universidad de Cartagena durante el Periodo Académico 2009 - 2013 Diofanor Acevedo José D. Torres Diego F. Tirado Ingeniería fracaso académico abandono de estudios Deserción estudiantil estudios universitarios El objetivo de este trabajo fue analizar las causas de la deserción estudiantil en el programa de Ingeniería de Alimentos de la Universidad de Cartagena. Se usó información del Sistema de Prevención y Análisis de Deserción en Instituciones de Educación Superior, herramienta del Ministerio de educación de Colombia. Se incluyó también información obtenida mediante encuestas presenciales, por correo electrónico, y llamadas telefónicas a una muestra representativa de 60 estudiantes de edad promedio 22.1 años que abandonaron estudios. La deserción más alta se presentó en los primeros cuatro semestres. El promedio por semestres fue de 10.75%, mientras que la acumulada de 55.87%, lo cual estuvo por encima del promedio en Colombia para programas similares con 10.53% y 52.89% respectivamente. La mayoría de los estudiantes atribuyeron su decisión de interrumpir los estudios a su situación económica. Se requiere diseñar planes que posibiliten un acompañamiento integral de los estudiantes en riesgo para disminuir la deserción. 2015 artículo científico 0718-5006 https://www.redalyc.org/articulo.oa?id=373544188005 es http://www.redalyc.org/revista.oa?id=3735 Formación Universitaria application/pdf Centro de Información Tecnológica Formación Universitaria (Chile) Num.1 Vol.8
