The interactionalist approach to construct definition (Chapelle, 1998; Chalhoub-Deville, 2004; Bachman, 2007), which highlights the prominent role of language use context, has been explored with a primary focus on applications in a summative assessment context. Attention has been drawn to design challenges and considerations and generalizability and fairness issues associated with highly contextualized tasks. Implications of the interactionalist approach for formative assessment, however, have not been examined in a systematic way.
This talk will focus on how to apply the interactionalist approach in design, development and validation of speaking assessment and discuss differences in key design issues and validation priorities for summative vs. formative purposes.
