Research in geography didactics and curriculum making are two fields that have been relevant to build the understanding on teachers practice in geography. The challenge for geography education therefore appears to be how to understand the relationships between the two in coherent and systematic ways. This paper engages with the specific meaning of being a subject specialist and the gap in the literature between curriculum making and didactics to understand that specialisation. A second gap is identified regarding the relationship between teacher practice and the professional practices encircling in-classroom activities. The paper finalises suggesting the use of the term expertise to address the dynamics of specialisation in a subject but also with its implication to teachers’ professional practice.
