A classroom can be designed to lead students through these stages. Class begins with awareness activities.
Data collecting methods are frequently overlooked but important.
It is valuable to introduce a variety of ideas and create critical comparison before selecting innovations. Planning strategies that help new approaches succeed is another critical but overlook stage. Action research is a good way to review successes. The role of the educator is to identify appropriate problems and facilitate learners as they go through the steps of problem-solving. The Deweyan model would recommend that classrooms begin not with descriptions of scholarship but with articulation of students' issues.
