Much of the current focus on maximizing the potential of ICT to enhance teaching and learning is on learning tasks rather than the technology. These learning tasks increasingly employ a constructivist, problem-based methodology especially one based around authentic learning. The problem-based nature of history provides fertile ground for this approach when combined with the scope for enquiry provided by primary and secondary sources. Barnhill forms one in a series of CD ROMs on themes within Scottish History which combine a wide range of historical sources and learning tasks including those built around authentic learning. The context is Scotland's History, but both the design of Barnhill and its learning tasks have a much wider application. (Contains 10 figures.)
