To learn, teachers need to be willing to take risks. Although they are classroom leaders, they don’t have to know it all. When we had our 20-year reunion of former and current OC teachers, one former OC teacher commented that admitting what she did not know to her teaching colleagues at her new school made her uncomfortable. Others pointed out that even as new OC teachers, saying “I don’t know” sometimes felt too risky. With more experience in the OC, however, they gained the confidence necessary to comfortably admit when they were uncertain or lacking knowledge. We began speculating about the sources of our initial discomfort. One teacher described how her own child’s teacher, in another school, felt compelled to maintain the appearance of always knowing exactly what she was doing even when she herself had many questions. She felt the need to demonstrate that her class was in control and that the kids were progressing at the same rate as those in the other classes. Without the support of other teachers, she could not disclose that she had much to learn. We speculated that a basic tenet of the OC—that learning is a process—encourages people to admit when their understanding is incomplete. No one, including the teachers, is expected to know everything. In a collaborative learning environment, people can say, “I don’t know,” and then use that acknowledgment— whether with students, parents, or teachers—as the starting point for learning. For example, when a child comes up with a question, a teacher is valued for responding, “Great question. Let’s go learn about it. I want to know the answer, too.” If the accepted approach is that “we’re all learning together,” then no one has to carry the burden of always being the expert. This is the heart of collaborative learning. Functioning as a learning community doesn’t just happen. In communicating with parents, OC teachers have to help them see that it’s okay for teachers not to know everything. The notion that “I don’t know” is a legitimate answer that forms a sound starting point for collaborative learning is a new idea for many parents.
