Interactive information retrieval (IIR) has become a commonplace activity in our networked world. People constantly use various search services in order to find relevant documents to satisfy their information needs or accessing services, communities, or people to get answers or recommendations. From a pedagogical viewpoint, IIR activities have some important properties. These include firstly, task dependence of information searching. In the real world, searching is bound to various task

Searching and finding is basically motivated by uncertainty in a situation, i.e., the need to find information to reduce uncertainty. Uncertainty also relates to selection of information channels and sources, search keys, and evaluation of search results. Thirdly, although we can outline the main phases of searching, we seldom can provide definite rules on how to proceed in IIR tasks. These ill-defined rules for proceeding are important elements of IIR instruction. Learners should be supported with motivating cues and hints, without providing too ready-made solutions. IIR instruction should also equip learners with transferable skills to manage searching in different operational IR systems and interfaces (Halttunen 2004; Morville and Callender 2010). Understanding how pedagogical solutions and technology can best support student learning in diverse learning environments remains a crucial line of educational research and development. Finding a suitable approach to rapid technological change and the identification of best practices are core ideas of "design experiments." Collins (1992) describes an educational research experiment carried out in a complex learning context, which explores how a technological innovation
