The topic of investigation may derive directly from teacher observations of children's spontaneous play and exploration. Project topics are also selected on the basis of an academic curiosity or social concern on the part of teachers or parents, or serendipitous events that direct the attention of the children and teachers. Reggio teachers place a high value on their ability to improvise and respond to children's predisposition to enjoy the unexpected. Regardless of their origins, successful projects are those that generate a sufficient amount of interest and uncertainty to provoke children's creative thinking and problem-solving and are open to different avenues of exploration. Because curriculum decisions are based on developmental and sociocultural concerns, small groups of children of varying abilities and interests, including those with special needs, work together on projects.
Projects begin with teachers observing and questioning children about the topic of interest.
Based on children's responses, teachers introduce materials, questions, and opportunities that provoke children to further explore the topic. While some of these teacher provocations are anticipated, projects often move in unanticipated directions as a result of problems children identify. As children proceed in an investigation, generating and testing their hypotheses, they are encouraged to depict their understanding through one of many symbolic languages, including drawing, sculpture, dramatic play, and writing. They work together towards the resolution of problems that arise. Teachers facilitate and then observe debates regarding the extent to which a child's drawing or other form of representation lives up to the expressed intent.
