Energy transformation in everyday devices taught to primary school children, using web-based software

A special real-life usability test was conducted, in which a number of teachers used a web-based educational software to teach energy transformations, occurring inside everyday appliances, to 230 primary school children, with the aim to study the way ordinary teachers behave when using such tools and measure their success rate in guiding pupils achieve knowledge. As the quality of the software is already proven, this qualifies as a test of its ease of use in everyday school situations. Knowledge improvement is measured and some interesting results are drawn.
