Sometimes I scratch my head when I read about the government' s efforts to improve schoo1s:new standards and tests to be applied, strict teacher evaluations, and threats of school closures and job losses. They frighten the school employees, not to mention the students. Instead of making people unable to solve problems or try new ideas-- which is what fear does to us-- research on school reform strongly suggests that policy -makers should encourage school leaders to take a more humane approach. In their study on the reform efforts of twelve Chicago public schools, Bryk and Schneider found that enabling positive social relationships between the adults was the key to successful school improvement and that trust was at the heart of those relationships.Trust in schools comes down to one thing:psychological safety or safety to speak one' s mind, to discuss writh openness and honesty what is and isn’t working, to make collective decisions.Yet this kind of safety doesn' t come easily to schools. According to Bryk and Schneider, the adults in school rely on each other to do their jobs correctly and with integrity (正直). The challeage is that our expectations are very diverse based on our unique backgrounds.At one school where I taught, each teacher had different expectations about hew much effort teachers should put into their work- -a big difference between the teachers who left af the 1ast bell and those who worked into the evening. And when expectations are uncoasci or unspoken, it becomes impossible for others to live upto them.We also make assumptions about the intentions behind a person’s behavior. As we a1l Imam, assumptions are often wrong. For example, parents and teachers my think the principal taml particular decision based on his career advancement rather than hat" s best for the studeata. don' t feel psychologica1ly safe to question our ssumptions and e aecmtiatm, trust itiea am the window and our relationships suffer.
