Like most situations -- this one has a lot of angles & perspectives:
Superintendent: UPSIDE: Reconfiguration would produce efficiencies and consistencies and allow existing resources to be leveraged to provide some good opportunities for students of all ages. Resources, or events, that may not be feasible in 2-3 locations could be affordable in one location.
DOWNSIDE: It's going to cost some money to reconfigure schools (think smaller toilets) and there will be some costs with moving equipment and changes in transportation. Also -- there will be much loud discussion and public angst which will distract from the everyday effort of running the District, and implementing the STEM program. BUT -- this is a good opportunity to deliver on the eventual cost-savings and efficiencies you have been promising.
Teachers: UPSIDE: They will work with more colleagues in their own grades and have access to more shared grade-specific resources.
DOWNSIDE: Kids are liable to be distracted by changing building so the first few days may be confusing. Teachers will be expected to deliver consistent curriculums -- may not be able to wander off and "do their own thing". Besides, moving is a pain in the ass and change is bad.
DOWNSIDE: Kids will be put through too many traumatic changes if they have to go to a new building. They like having their kids in one place. They don't want to drive to Forestdale. They didn't vote for that! And, why do they call him "Dr." anyway -- does he have a medical degree?
(One thought about the "traumatic changes" some folks are worried about: This is 21st Century Sandwich. With so many kids expected to routinely adjust to Step Mother, Step Father, Mom's Boyfriend, Dad's Girlfriend, Two Moms, Two Dads, raised by Grandma/Grandpa, joint custody, custodial parents, Mommie's house, Daddy's House, job relocations, mortgage foreclosures, etc. --- I'm thinking they can probably adjust to changing schools every three years -- especially with all of their friends being in the same building with them.)
Parent Group #2: UPSIDE: Everything, great idea.
DOWNSIDE: Absolutely none!!!!!.
Parent Group #2: UPSIDE: Oh, are they thinking about changing the schools? I haven't heard anything about that! Will this impact Pop Warner or Youth Soccer?
DOWNSIDE: Oh, are they thinking about changing the schools? I haven't heard anything about that! Will this impact Pop Warner or Youth Soccer?
School Committee: UPSIDE: Might be able to do something that will have a long-term impact on the School Department -- without receiving a subpoena!
DOWNSIDE: Few members have any real background in education (and a couple act like they have no education) -- They know that no matter what they do -- somebody will be pissed off!
CONCLUSION: The Committee will catch Hell either way. The only thing they can do is attempt to make a rational, educationally sound decision based on the information presented to them. They have heard from the public ad nauseum over the past several weeks -- there is little to be gained by listening to the same people repeat the same things one more time. I think the School Committee's question to themselves should be: "Have we heard any legitimate issues raised that conflict with the professional judgement of the Superintendent and his team?'
