A recent review on TPACK research has concluded that there is great need for empirical research regarding the development of this specific knowledge base. Based on a Venn diagram visualization of the framework we created a graphic assessment tool to (a) tap into teachers’ understanding of the proposed TPACK sub-domains and to explore (b) the usefulness of this tool for professional development. Extending the common TPACK diagram, we introduced variability in size and amount of overlap of the basic sub-domains (TK, PK, CK). The pilot study presented here reports the results of semi-structured interviews with two German in-service teachers. Overall, the teachers’ understanding of the knowledge sub-domains raises important questions regarding our conceptualization of what TPACK is and how it could be further developed. The hypothesis derived for future research is that TPACK is related to both a better integration of the sub-domains as well as a better understanding of the distinct basic sub-domains.
