Hi Nik,
It seems to me that you just need to create a course for each lecturer per scheme of work. That the course will be in the weekly format and that you make the lecturer responsible a 'Teacher' on the course (editing teacher). Then they can create assignments etc. for the SOW. And they can also change the start date of the course in the course settings.
You can then enrol students on the course and they will see the material / assignments.
