  We report a course on teaching in physics lab for teachers enrolled in
Formative Active Training, which actually allows to obtain the teacher
qualification in Italy. The course was designed with the purpose of showing in
practice what means active learning in physics and how effective activities can
be realized in practice. Two different type of teachers attended to the course,
a small group, with physics or mathematics degree, for teacher qualification in
secondary school of second grade (age 14-19) and a more numerous group for
qualification in secondary school of first grade (age 11-14), usually with a
different science degree such as biology, environmental sciences and so on. We
compare this training in physics lab between the two groups and with other
experiences we performed in previous years in pre-service education and
updating courses for teachers in-service.
