'So, what have we learned?': creating and evaluating web based history teaching and learning resources. Over the past two years, Philippa Martyr and Paul Turnbull have been working with several of their colleagues to create "Pictures of Health", a series of web-based modules focused on aspects of the social history of health and disease in Australia, c. 1860-1920. In this presentation, they will discuss some of the key educational issues that have arisen in the course of designing resources for the web, and report on the first trial of one of their modules with a class of Australian undergraduate students.
