At GCSE we follow the CCEA syllabus, and the specification requires us to teach ‘one case study of sustainable transport mangement in a city within the European Union(excluding the British Isles)’. I did not have any off the top of my head; luckily the text book has the example of Freiburg, Germany. Below are the resources that I put together to teach this part of the course.
I could only find limited sources for my research as my German language ability is non-existent!
However I have produce a powerpoint and an accompanying sheet for students to record their notes.
I also used the pages 196-197 from the textbook Geography for CCEA GCSE.
