The experimental internship with professional relevance is aimed at all students on the dual-subject Bachelor's degree programme in Physics with the aim of becoming a teacher, as well as students on the Master of Education degree programme with a focus on economics or special education. It comprises one semester and is offered both in the winter semester (two groups of 12 students each) and in the summer semester (one group of 12 students). The module is worth 8 CP and consists of a four-hour practical laboratory course and a two-hour seminar. The practical course takes place on Fridays, the seminar on Monday mornings. Participation in both courses is compulsory.

There are three main focuses in the practical course:

• Firstly, students should be given the opportunity to deepen and extend their technical and experimental skills, which were laid down in the basic practical course in physics (phy211 and phy215 or phy212), in relation to school physics. To this end, a physics topic is scrutinised experimentally on each experimental day. Current topics include mechanics, optics, electricity, magnetism and thermodynamics. For students specialising in H or R, this in-depth study is continued in the experimental practical course for secondary, intermediate and special schools (phy213). In the seminar following the respective laboratory day, the topics are discussed from a didactic perspective and with a view to the professional field of school.
• Secondly, the discussion about the didactic benefits of the experiment and its integration into the classroom will be deepened. Here, the experimental practical course builds on previous courses such as Learning and Teaching Physics (phy260) . By incorporating the learner's perspective, the role of the experiment in the cognitive process is emphasised here. This is supported by excursions on the historical background of the experimental science of physics, for which the experimental practical course can draw on the pool of historical experimental replicas from the former specialisation of the History of Physics working group.
• Finally, the event will also focus on direct contact with pupils. To this end, a school class is invited to the practical course on at least one date, with the students conducting experiments together with groups of pupils. This gives the students the opportunity to gain elementary experience of how pupils interact with the physics experiments at an experimental station they have designed.

Experiences from the module are taken up again in the didactic modules of the Master's phase(phy410 and phy420/423/424) and, if necessary, in the Bachelor's thesis.

The students generally work together in groups of two (there are also deviations for certain topics) and prepare a protocol for each laboratory day as an examination.
