There are many different kinds of knowledge and ways of knowing: “tacit knowledge” that we possess but are not consciously aware of; “implicit” knowledge that we may be aware of, but have not yet articulated; and “explicit knowledge” that has been articulated in written or spoken form (Fazey et al., 2006; Reed et al., 2010). Knowledge includes different “types” of information that may have been derived from a range of sources including personal experience, observations and research results. As such knowledge does not necessarily consist of “universal truths” and may depend on the unique interpretation and reality of each individual (Zermoglio et al., 2005).
