In this book, Didáctica universitaria en entornos virtuales de enseñanza-aprendizaje ('University education in virtual teaching and learning environments'), the authors review the most important issues with respect to virtual teaching and learning environments. E-learning is becoming the main focus for 21st century universities, given that, currently, most of them are undertaking virtual learning activities. The highlight of this work is the detailed study of all the elements involved in the e-learning process: teachers, students and materials. It also pays special attention to the planning of teaching, the development and monitoring of online study activities, and the assessment processes; taking into account, for each, the opinion of the teachers and students involved, and incorporating a great number of examples gained from the day-to-day professional activities of the authors.
