Scaffolding strategies in electronic performance support systems: types and challenges

In the study described in this paper, the major components of an electronic performance support system are described and the use of scaffolding techniques within such electronic environments is explored. Four different types of scaffolding are discussed: conceptual (supportive) scaffolding, metacognitive (reflective) scaffolding, procedural scaffolding and strategic-intrinsic scaffolding. The paper also discusses some of the challenges that developers face when they plan to include scaffolding techniques as part of an electronic performance support system.
