When educators do the hard work necessary to implement these principles, their collective ability to help all students learn will rise... The rise or fall of the professional learning community depends not on the merits of the concept itself, but on the most important element in the improvement of any school--the commitment and persistence of the educators within it.Reading DuFour and talking to educators, I think that teachers' commitment and persistence are an outcome, as well as an input, in the PLC process. The collaborative approach helps teachers sustain the high energy needed to keep finding and trying new approaches to move every student forward. Where one person working alone could run out of steam, the team approach fuels lasting effort.
