The integral part of Montessori education is that learning is not confined in the classroom, but extends beyond the classroom. Learning involves moving out of the classroom, or what we call, "Going Out". Children take what they've learned from the classroom and explore how it works out in the real world. This becomes more meaningful as they come to understand that the answers to their questions do not lie within the classroom walls, books, or with teachers.
They meet the experts in the field, ask them questions, investigate, and draw conclusions from their research. An example would be visiting a wildlife preserve and meeting an ornithologist to learn more about their research on birds.
