Gonzalez (2006) and Jahnke (2012) compare the hermeneutics of Gadamer and Ricoeur, but a discussion of the application of hermeneutics in research is missing.
In general, hermeneutics is the theory of interpretation and concentrates on how we read and understand different texts and types of communication.
One way to scaffold your students' understanding of hermeneutics is to have them write their own essays.
Hermeneutics was originally developed for the interpretation of classical texts, religious documents and legal manuscripts (Rennie, 2012).
Later, through the efforts of Schleiermacher (1768–1834) and Dilthey (1833–1911) the scope of hermeneutics was extended to support the interpretation of all kinds of texts.
