The purpose of this qualitative study was to learn more about how teachers deal with a reflective teaching approach aimed at developing their competencies in analysing and facilitating classroom discussions on socio-scientific issues. Three cases of teachers' journeys through the project are reconstructed and characterised. We posit that each teacher benefited from the project according to his or her individual situation, needs and learning style. A number of modifications to the project design are proposed and can be summarised by the idea of assisting teachers more closely and more individually as they pass through the reflective teaching process.
