It can be argued that one of the most important things teachers do is create a "culture of learning" in their classrooms. It takes a lot of intentional, expert and careful planning of children's learning experiences to create such an environment, and is truly inspirational to observe in action. Charlotte Danielson, author of Enhancing Professional Practice describes a culture of learning in its ideal form:
Students demonstrate through their active participation, curiosity, and taking initiative that they value the importance of what they are learning.
Instructional activities and classroom interactions convey high expectations for all students, and students have internalized these expectations.
Students demonstrate attention to detail and take obvious pride in their work, initiating improvements in it by, for example, revising drafts on their own or helping peers.
As you can see, it's not just what the children are learning at school that is important. At least as important is how they are learning and that they are internalizing a love of learning that will last a lifetime!
