This is a course that integrates within a 3-year Environmental Sciences degree (Bachelor). This degree is given by the Universidade Aberta (Open University of Portugal) in e-learning. The objectives of this course are essentially to study the biological classification as well as their evolution in temporal scale. Videos were used to explain evolution, illustrate the scheme of animals and their behaviour To achieve this objective several links were used to free videos on the internet. Descriptions of certain behaviour are much easier to understand when viewing animals doing it compare with a text description. The visualization of videos by students is advice but not compulsory. Some of the student used it others no. From written evaluations was detected that the students that watch the videos have better results in identification of animals, principally if the photo is taken while an animal is moving. A small survey is done to evaluated how the students considering videos important to their learning.engconference object
