Teachers and trainers in adult education–Investigating the dimensionality of their knowledge about methods and concepts of teaching and learning

Knowledge about methods and concepts of teaching and learning is considered an important aspect of the pedagogical-psychological knowledge (PPK) of teachers in adult and continuing education (ACE) for designing helpful situations of teaching and learning. The article poses the theoretical-conceptual and empirical question of the dimensionality of this knowledge using a sample of N = 212 ACE teachers. The results point to the multidimensionality of this knowledge in the ACE field. The findings are critically discussed in terms of their robustness and scope, as well as possibilities for the further development of the test.
