I plan on leaving my materials for the next teacher as well as a lot of things in my apartment for the next person. My previous teacher started out with nothing because the school was new to the EPIK program and he left a lot of materials for me. I really appreciate them, but don't use them very often. More than likely, I find something on my own or make something myself. I take the previous teacher's things as a resouce and a place for ideas. I try not to use the same things because the students were exposed to the material the previous year. So doing my own thing prevents repetition and I actually know what is going to happen next (I've used other's PPT and came upon many surprises).
I hope that the next teacher will do the same. He/she is going to have lots of deskwarming hours so, browsing my files or the previous teacher's files can be a many hours of brain storming. Luckily I don't have to make detailed lesson plans, so if the schools change their mind of actually needing one, then the new teacher is on their own.
Isn't this the whole purpose of coming to Waygook? To share ideas and many times your hard work? At least we don't have to go through the whole copy right and citing here.
