This  paper  summarizes  the  results  of  the  research  project  <span name="style_italic">El  aprendizaje combinado (presencial y no presencial apoyado  por el uso de internet)  y su utilidad para el desarrollo de las habilidades de expresión escrita</span> [The  Use  of  Combined  Learning  (face-to-face  and  virtual) in Developing Written Expression Skills] conducted in 2011-2012 with the support  of the Office of the Vice-President for Research of the Costa Rica Institute of Technology.

The outcomes of the project were evaluated through the analysis of products selected, panel discussions with the participant teachers, interviews to the participant  population,  and the analysis of the researcher’s project journals.  This study concludes  that  combined  learning contributes to improving written expression  skills, since it involves the development of skills and competencies to accomplish different tasks related to the access of knowledge  on a specific topic to be developed in writing, text planning, text production, proofreading and dissemination of the final product. grades, and there was a teacher working in both contexts).
