Studies of Integrated Learning Systems have endorsed their potential for en
hancing pupils' learning, but they have also highlighted the importance of
the context and method of use in influencing the nature and quality of the
learning outcomes. This paper describes an evaluation of a new version of t
his type of software which is explicitly designed to make links with severa
l external factors, in particular with another software application for sup
porting investigative work in practical science. The evaluation adopts a si
tuated approach which explores the contributions to the learning process ma
de by the teacher, the student as well as the software itself. The results
amplify the value of small group working, the role of the teacher and the a
spects of software design which help to secure the benefits of the system.
