Constructivist theorists view the educator as a facilitator and guide in helping children construct new understandings linked to prior knowledge. Carl Rogers' humanistic approach maintains that self-initiated learning relevant to the individual will be the most sustainable. The role of the teacher is to actively listen to students and be available as a resource to students. (Rogers, 1969) Behavioral views focus on extrinsic motivation in learning, where constructivist theorists suggest that motivation comes from the intrinsic feeling of accomplishment through successful completion of tasks. Humanists theorize that motivation is based on the need to satisfy basic needs and to grow as people grow. (Duchesne et al. 2013) Humanistic theories of education, which emphasize self-assessment and reflection, can present difficulties and demonstrate the assessable outcomes that society expects from modern schools (Porter, 2000 ). Behavioral methods of viewing learning as observable changes in behavior allow for clear expectations and evaluable outcomes. Constructivism encourages educators to observe and reflect on children's current and progressive understandings.
