Under the Dalton Plan the teacher's principal job is to
instruct or teach by answering the questions asked by
individual children or by groups of children.
The teacher does not attempt to throw information into
their minds as one shovels coal into a furnace, but rather
studies their needs to discover what she/he can do and what
she/he should know in order to help their research.
