First Days of Meridian Park

I realized today that if teachers are not given enough time to meet with other teachers or observe other teachers in their school the idea of building a professional community in teaching may be very difficult. First to get time money is needed. The money for the substitute to be in the classroom leading a lesson so that teacher can meet with another formally (not at lunch or in the bathroom) or view another teacher teaching. Second as a teacher I would have to be willing to give up something I may really enjoy doing with my class such as reading a loud to them or daily journal time when the substitute can come in and cover my class at a time that maximizes my own teaching and planning. Third another teacher in my building has to be willing to let me observe them in their classroom and/or want to collaborate on a student's learning/lessons. Surprisingly the last two are sometimes the hardest to overcome but the most rewarding for all teachers involved. How do I observe/collaborate or just work with a teacher uninterested in building a professional learning community FOR TEACHERS?
