Table 1 Type of proposition error
From: Collaborative concept mapping with reciprocal kit-build: a practical use in linear algebra course
Type of error | Description and example | Minus point |
|---|---|---|
Fatal error | The students did not draw an essential link between the two nodes. The students created a wrong definition, e.g., the vector was defined as a directed line segment; the domain and codomain were linked to the inner product space/general vector space, not to the function; a vector space was defined as a subspace of an inner product space. | − 10 |
Moderate error | The students connected a partially incorrect relation, e.g., the measurement-related nodes were connected to the vector and not to the inner product function; the axiom-related nodes were connected to the inner product space, not to the inner product function. | − 5 |
Minor error | The students described partially incorrect linking words, but the relation was correct, e.g., a “must” word was not included when defining a relation to the axioms. | − 2 |
