A mind map is a visual, non-linear method of noting information. Mind maps usually follow a tree-like structure, with branches coming off a central topic. There is no set way to mind map – it can be as creative as the individual learner prefers, using colours, symbols and images if so desired (see examples 77.1 and 77.2). Tony Buzan, often cited as the inventor of mind maps, recommends making your mind map as colourful and visually appealing as possible, even preferring curved lines to straight, in order to stimulate the brain. Mind maps can be used to help learners visualize search problems and think through the search process, identifying concepts and keywords. Mind maps have been shown to improve students’ searching, with students making the link between the mind map and the search process (Webber, 2002).

A concept map is similar to a mind map, but in addition contains lines that show the relationships between the concepts displayed within the map. This can be used to help plan search strategies, indicating how different concepts should be connected (AND, OR, NOT).

There are many computer programs (e.g. MindGenius, www. mindgenius. com; iMind map, www.thinkbuzan.com) and websites (e.g. bubbl.us, http://bubbl.us; Mindomo, www.mindomo.com) that will help you create mind maps. However, pen and paper is often the most preferred method!

Provide each learner with a large blank piece of paper and some coloured marker pens. Ask your learners to create a mind map of the topic they wish to research. The main subject should be placed in the centre of the paper. Subtopics are the ‘branches’. Ask them to note any information they like. Encourage the use of colours and images – learners should make this map their own.

Once learners have completed their maps, explain how this can then be used to select keywords, identify search concepts and combine keywords. For example, ask learners to link which words should be combined with AND/OR and which words they might want to exclude using NOT. Ask students to mark which words they used in their searches. The mind map can then be used as a reference for learners to return to when researching the topic.
