The answer to the question "paper or plastic?" has been established right? The impact of fossil fuel use in the production of plastic bags along with their inability to break down in a landfill or be recycled clearly makes plastic bags an inferior option, right? Watching this video, which claims that the answer is clearly not so simple, really pushed my mental model about this topic. It forced me to rethink a "truth" that had established itself over time and seemed set for hall of fame for truthdom. How many "truths" in education are we perpetuating each day through our instruction, procedures, systems, and structures? Are we blindly continuing to make choices for kids that aren't maximizing their opportunities? How are you questioning everything without being paralyzed into a state of inaction?
