Emerging Research Efficacy Through Scaffolded Research Practice: An EFL Preservice Teacher Autobiographical Narrative

EFL preservice teachers ’ research efficacy, as perceived competence to perform tasks in research, is crucial to their research engagement. This autobiographical narrative inquiry investigates the contribution of scaffolded research practice to a female EFL preservice teacher ’s research efficacy.The data were collected through conversations, notes, journals, and portfolios.
