Equipping teachers for differentiation

Teachers are expected to tailor their instruction to accommodate differences between students, in order to give all learners the opportunity to develop to their full potential. This is also called differentiated instruction (DI), and it requires teachers to continually monitor students’ progress towards the lesson goal and adjust their instruction accordingly. This is a complex skill for many teachers that they do not always implement. The goal of this dissertation was to research how educators can be supported in providing differentiation.

In Study 1 we observed secondary school teachers with strong DI skills in their classrooms and interviewed them afterwards to analyse their decision-making processes. The findings of this study informed the design and implementation of a professional development program in Study 2, which was based on a whole-task approach where the participant teachers work on authentic tasks that require the integration of skills and knowledge, increasing the likelihood of transfer to practice. The impact of this professional development program on teachers’ DI practices was examined in Study 3, both from the teacher and student perspective. Results from both perspectives showed that all teachers made more intentional adaptations.

To explore whether the findings of the first three studies were transferable to another context, we shifted the focus to students with hearing and/or communicative impairments (HCI). Instead of a single teacher, often a team of professionals has joint responsibility for HCI students’ education. In Study 4, we researched what providing DI and interprofessional collaboration in the HCI context looks like, by conducting a systematic literature review and an exploration of practice through focus group sessions.

We found that there are four phases (preparing a lesson series, preparing a lesson, enacting a lesson, and evaluating the lesson) and five principles (work in a goal-oriented way, monitor continually, challenge all students, adapt the instruction, and stimulate self-regulation) that could be identified in DI across various educational contexts. The four phases and five principles can be used as a framework to support educators in improving their DI skills and thus making good, informed decisions that allow all their students to realise their learning potential.
