EDUCE is an Intelligent Tutoring System for which a set of learning resources has been developed using the principles of Multiple Intelligences. It can dynamically identify learning characteristics and adaptively provide a customised learning material tailored to the learner. This paper describes a research study using EDUCE that examines the relationship between the adaptive presentation strategy, the level of choice available and the learning performance of science school students aged 12 to 14. The paper presents some preliminary results from a group of 18 students that have participated in the study so far. Results suggest that learning strategies that encourage the student to use as many resources as possible are the most effective. They suggest that learning gain can improve by presenting students initially with learning resources that are not usually used and subsequently providing a range of resources from which students may choose.
