ABSTRACT Through collaborative practice research with the goal of identifying alternative discourses that can challenge expert-led knowledge in parent education, this study examined a community-based home visiting programme conducted by a social work practitioner serving disadvantaged migrant families in Shenzhen. To obtain diverse information, data was collected by three major methods, including in-depth interviews, participant observations and document reviews. Findings of this study shed lights on the social work research-practice partnership through a reflexive knowledge co-construction approach which helped to produce alternative discourses that considered parents’ experiential knowledge and emphasised a system-oriented perspective. By embracing the alternative subjectivities constituted by alternative discourses as collaborators and co-learners, the practitioner and researcher also demonstrated abilities to think about new possibilities for parent education practice and research. Implications for future empowerment-oriented social work practice and research in family and parent education fields were also discussed.
