Methodological Implementation

The conditions necessary for the success of inclusive learning are to be identified on an individual and on a familial level, on a class and a school level, and in consideration of regional or local circumstances. As this requires a broad information basis, INSIDE consists of three substudies. The first substudy began in Spring 2018 with a national survey in which school principals from selected schools in the lower secondary tier in all of the 16 federal states were contacted and asked to participate. In order to identify conditions for pupils’ success, a longitudinal analysis with surveys conducted at more than one point in time is indispensable; for this reason, after the survey of the principals themselves, a targeted selection of schools in which pupils with special educational needs are taught was made. In these schools, the principals and teaching staff, the special needs teaching staff, the pupils and their parents will be accompanied over a longer period of time. By way of an in-depth survey of teaching staff and special education teaching staff or specialists in a further targeted selection of classes with different key subjects, additional information will be recorded which cannot usually be gathered in large scale investigations of this kind.


The method for answering the research project’s questions is split into three substudies:

  • Substudy I: School principals in the lower secondary tier in all 16 German federal states were asked to participate in an online survey.
  • Substudy II: Building on Substudy I and data from the official school statistics, a targeted selection for a school sample was made; these schools will then be monitored longitudinally. Used here will be competence tests and questionnaires for pupils, questionnaires for principals, teaching staff and special needs teaching staff or specialists. Furthermore there will be telephone-interviews for the parents.
  • Substudy III: Selected teaching staff and relevant special needs staff or specialists will be asked to keep a teaching diary.
