Guest Editorial

The papers presented in this issue of Education and Information Technologies dis- cuss the theme Human Computer Interaction (HCI) and Educational Tools: Theory into Practice. This theme was selected as the basis for exploring the synergy which exists between HCI and the design of educational tools, in the anticipation that in- sights from each of the two areas would prove mutually enriching. A further over- arching theme concerns the potential of advanced computing technologies not simply to support but to transform teaching and learning.
