Last weeks we carried out our experiment at 2 schools, in 8 classes. It was very nice to experience all we set up last 1,5 years. We had some trouble with getting responses from parents for the informed consent, but luckily we got ethical approval from the Leiden committee to ask for retrospective permission. For te first school we visited, this still has to be finished. The second school was quicker in this, so there we are already sure which data we can and can not use. Because of that I processed the data of this second school already in SPSS, together with the questionnaires some parents filled in. This progress is very exciting!
