Can anyone recommend me studies that focus on dynamic assessment procedures, especially following an interventionist approach, in assessing pre/in service teachers' pedagogical or content-related knowledge in EFL/ESL context?
Sure. The study by Kyriakides et al. (2017) and the one by McNeil (2016) could be relevant. Here are the full citations.
