Strategies student-teachers employ in classroom interaction with pupils during teaching practice periods are surprisingly understudied, considering that the teaching practicum provides a central arena for student-teachers learning to become teachers. This study investigates the primary strategies student-teachers utilised in classroom interaction and the multiple qualities of these strategies. The data were collected from 31 student-teachers during their teaching practicum through stimulated recall (STR) interviews focusing on challenging and empowering critical incidents that student-teachers chose from their video-recorded lessons. The results showed that in challenging classroom incidents, student-teachers applied predominantly reactive behavioural strategies, whereas in the empowering situations, student-teachers primarily employed proactive cognitive and behavioural strategies. Use of proactive cognitive strategies was typically associated with positive meaningful experiences; hence, they setting the stage for utilising a more diverse set of proactive strategies in the classroom. Implications for teacher education programmes providing student-teachers authentic learning opportunities that promote proactive strategies are discussed.
