The dataset contains test results from an intervention study with intermediate learners in two high schools in Berlin (2018-2019). In total, 60 students participated in three groups (= classes). The intervention materials and tests are published as well. A key question of the still ongoing research project is: How can vocabulary competence in a historical language such as Latin be acquired and deepened by using corpus-based, i.e. context-based, methods? This question is based on a broad understanding of vocabulary that refers back to theories of the mental lexicon.
