I have a 2000 word essay to write with the title, "What do we mean by pedagogy? Explore your developing understanding of the term."

I am struggling a lot on what to write about this as its such a broad term. Any suggestions on what to write about for this? any framework/plan would be very much appreciated! I have a bunch of sources to take things from but I just really don't know what I should be including as its so complicated!
