Specifically, focusing on differentiation related to goals, instruction, and practice, based on Prast et al.'s (2015) differentiation cycle. To assess this, a group of experts (N=23) was assembled consisting of teachers, teacher educators, researchers, and educational consultants, all of whom were considered experts in the field of differentiation and/or didactics in primary humanities/STEM subjects. The research design consisted of a combination of the Delphi technique and focus groups, in which the experts' views were first obtained individually through a questionnaire. The input from this questionnaire was then used to guide the focus group discussions. Outcomes included that a basic goal for all students in the classroom can be defined and that differentiation lies more in supporting lower-level students and providing additional challenge to higher level students, perhaps less in adjusting goals. Concrete differentiation strategies were discussed by the experts and are described in the results. Follow-up research can focus on which strategies of support and challenge are most efficient and effective and the effect of setting differentiated goals versus a basic whole-class goal on the learning performance of students in the primary humanities/STEM subjects.Show less
