In this paper we review the relevance of the models of Collaborative Learning (CL) in Primary Education, also exploring the integration of Information and Communication Technology (ICT) in these processes. Through the case study method, the main objective of this article is to describe the design, implementation and evaluation of a collaborative experience with ICT involving students in the 5th year of Primary Education in a Spanish school. Information has been collected from all those involved: teachers, tutors, teacher ICT support and students from two classes participating in the investigation. The results confirm the fact that ICT provide tools and channels that have multiplied the possibilities to carry out collaborative projects, providing quality assurance to share and communicate. The experience presented provides evidence to confirm this, and at the same time, confronts the dominant methodology based more on individual learning where the teacher continues to exercise the role of sole transmitter of knowledge.
