Our colleagues in the great white north – the Canadian Educational Developers Caucus – have produced a rich looking guide to building rapport between ed developers and academics/teachers.
I haven’t had a chance to dig into it deeply (it’s more than 100 pages) but this looks pretty valuable.
The guide – and an earlier one called the Education Developers Portfolio – can be found here https://www.stlhe.ca/affiliated-groups/educational-developers-caucus/guides/
