We at Curtin University also evaluated the use of an interactive multimedia package, the Osmosis Program, and also failed to find significant difference. We could have gloomily added our research results to Thomas Russell's website. However, our results made us realize that the evaluation of learning which we employed in that particular unit was at best incomplete and at worst a poor indicator of any learning which may have taken place. Perhaps, as in our case, many of the website examples tried to evaluate good learning innovations and techniques with assessment instruments which could not record or reflect any significant differences??
