Spring Fever is based on a well established and successful Dutch programme, with a strong evidence base that demonstrates the positive impact it has had.
A Dutch evaluation study (Martens, M. et al, 2010) among 1002 pupils (with a control group) in years 6, 7, and 8 of primary school in the Netherlands shows an increase in knowledge about relationships, human sexuality and sexual abuse after the lessons. Children who have received these lessons also appear to have developed a more positive attitude towards homosexuality, and are more assertive than children who have had no or only ad hoc education in the area of sexual health and relationships. The effects are not equally pronounced for all groups of children. Additionally, teachers note that children are more open about relationships and sex and find it easier to correct their classmates if they demonstrate undesirable behaviour. There is less unease at school and fewer problems in the interaction between boys and girls. Evaluations show that the teachers have a positive opinion of the teaching package, thanks to its user-friendliness and the way in which the lessons are tailored to the children’s perspective and level of development. Furthermore, the children experience the lessons as instructive and fun. They also feel that the lessons are given at the right moment.
