Literacy and thinking tools, such as Venn diagrams, are construction tools for the mind. Just as carpenters use tools to construct a piece of furniture, literate thinkers learning science can use tools to construct new scientific understandings. Like tools used by a carpenter, some literacy and thinking tools are purpose-built for science education; Josephine used a Venn diagram tool because she wanted to compare her pet bird to a bald eagle. Just as a screwdriver is built to slot into the head of a screw and rotate it, you can use literacy and thinking tools for subject- and text-specific purposes.
In this chapter, we examine some characteristics of literacy and thinking tools (Whitehead, 2001, 2004). A list of these tools, together with the chapters associ-ated with their use, is provided in Table 2:1.
