Adaptivity challenges for relational scaffolding

Overview & Synopsis

Scaffolding is a mean to support students’ ability of expressing ideas in written language and to foster conceptual understanding. It is well known that scaffolds in words and chunks must be topic specific and adaptive to the individuals’ steps of proximal development, but not what that means in detail, for example for percentages. The case study reported in this poster investigates which topic specific scaffolds are needed and reconstructs students’ challenges with topic specific scaffolding as well as effects on their conceptions.
