Methods 2 47 sessions that were organized to check the coding (inter-rater reliability). I also regularly presented the research to experts at national and international conferences, and each sub-studywas subjected toblindpeer reviewas it was submitted to international academic journals. For me as researcher, continuous reflection was also stimulated by the use of a notebook during the whole research process, which can benefit reliability (cf. ‘t Hart et al., 2005; Matlerud, 2001). Also for purposes of reliability, a detailed description of how the study was conducted is provided (cf. ‘t Hart et al., 2005). This makes the research transparent as a whole, and opens ways for theoretical generalization and transferability to other contexts (Robson & McCartan, 2016). With regard to research integrity, the Netherlands Code of Conduct for Research Integrity for scientific research at Dutch universities (VSNU, 2018) was followed. This code is based on the principles of honesty, scrupulousness, transparency, independence and responsibility. To maintain integrity, a data management plan was prepared before the empirical studies began, in accordance with the guidelines for data management of the Dutch National Centre of Expertise and Repository for Research Data (DANS 2015). All interviews and focus groups were recorded and the anonymized transcripts and reports stored in DANS26, and are accessible for other researchers after permission of the research team. All participants signed an informed consent form (see Appendix VIII), thereby agreeing with their voluntary participation, the anonymous use of the interview material in this research study, the storage of the anonymised data in DANS, and access to and use of these materials by other researchers after permission of the research team. The participation of the teachers in the individual interviews and the participation of alumni and teacher educators in the focus groups were are at the heart of my research. It is for this reason that I consistently use the term ‘participant(s)’ instead of ‘respondent(s)’ to refer to them. An important question that was constantly present throughout the research process was: ‘Am I doing justice to the participants?’ 26 DANS is the Data Archiving and Networked Services of the Royal Netherlands Academy of Arts and Sciences (KNAW) and the Netherlands Organisation for Scientific Research (NWO).
