Summer is in full effect.  Swimming, family trips, and other leisure activities are also in full effect.  As a result, I am sure that professional learning is not ranked very high on the summer fun list for most teachers.  The funny thing is the summer presents the most optimal time for exploring very meaningful professional development ideas.  I have come to understand the value of the of a well-timed summer professional learning task, and I would like to solicit other educators for their ideas for teachers of various levels of experience.  Please comment below with a professional learning idea that you have benefited from and would like to share with others.
