Collaborative learning is a strategy that organizes classroom activities in order to generate social and academic learning experience in it, students work in groups. In this paper the effectiveness of the implementation of this strategy is reported using a web page designed for this purpose with a group of second graders of secondary (group A) and compared with a group that took normal classes (group B). An analysis of standardized conceptual gain was performed and it was found that group A was higher than group B, which indicates that there was this strategy along
with that web page was that improved understanding of the concepts about Astronomy and Cosmology in student’s
high school. According to these results, it is intended to design an online course on these issues to go a step further in using digital tools for teaching physics to secondary level.
