The CILIP Information Literacy Group (ILG) has published revised versions of its Research Smarter resource sheets "designed to help secondary school students research effectively and be information literate". There are 10 of them, each 1 or 2 sides of A4, "made available under a Creative Commons Attribution-ShareAlike 4.0 licence, so they can be shared, reproduced and re-used widely". Topics include: Referencing your research; Why do I need to research my topic?; Research is a messy process; What search engines are out there? They were originally developed for the TeenTech challenge: the Link your project to what your end user actually wants and needs sheet could have done with a little more work to make it generically useful, I think, but they generally look useful.
