Research questions
These problems and considerations lead to the following research questions.
Question 1: What conceptions with particular attention to pre- and misconceptions emerge concerning functional thinking of students of lower secondary schools (grade 7/8)?
Question 2: How should dynamic materials be designed to support students of lower secondary schools to develop appropriate mathematical understanding and thus to reduce errors due to pre-
and misconceptions concerning functional thinking?
Question 3: What is the influence of dynamic materials on conceptions and internal representations of students of secondary schools particularly with regard to the understanding of
the co-variational aspect of functional thinking?
