Abstract
The following empirical study examines the acquisition of expertise. The model structures in the domain of empirical methodologies were examined in a time period of two semesters. At each measurement point (N = 5), the model structures of the reference groups were compared with those of the group of learners. The group of learners consisted of (N = 31) students who did not have any experience with research methods and their theoretical foundations. The results indicate that the external criteria enabled a precise assessment of learning dependent model change.

Homogeneity in the reference model of the novices
The number of compared single ratings for the novices is n = 3518 (Tables 5 and 6).
-
The group produced sufficiently homogeneous ratings. A model derived from the closeness rating (and combinations with it) can be interpreted as a model of the group.
-
The group produced sufficiently homogeneous ratings. A model derived from the contrast rating (and combinations with it) can be interpreted as a model of the group.
-
The group produced sufficiently homogeneous ratings. A model derived from the combined measure (and combinations with it) can be interpreted as a model of the group.
-
The group produced sufficiently homogeneous ratings. A model weighted by the confidence rating can be interpreted as a model of the group.
The derivation within the ratings of the novices is small enough to interpret their model using all ratings and combinations thereof. We can understand their model to be a consensus model.
Homogeneity in the reference model of the advanced learners
The number of compared single ratings for the advanced learners is n = 4208 (Tables 7 and 8).

The group produced sufficiently homogeneous ratings. A model derived from the closeness rating (and combinations with it) can be interpreted as a model of the group.
