Boolify.org is a website that helps users learn search methodology. Both keyword techniques and boolean operators as well as explaining how to quickly analyse websites for reliability. Well worth knowing about if you teach good practice web searching – which all teachers would benefit from if not confident already. A great way to model web search work for any class because it visualises what the user is actually doing. See what you think.
