The Dalton Plan was McQueen's major reform and by it he attempted to transform the whole school. He was however also greatly influenced by at least two other teaching procedures. The first of these was the project methods which was based on the ideas of W. H. Kilpatrick who in turn was influenced by John Dewey. The project method set out to "allow children to follow their own ways in purpose, planning and execution and judgement." Many other schools at the time were also introducing similar methods based on Kilpatrick's work.
