Constructivist theorists point to the educator as a facilitator and guide to help children build new understandings related to previous knowledge. Carl Rogers' humanistic approach argues that self-initiated learning that is relevant to the individual will be the most long-lasting. The teacher's role includes actively listening to students and being available as a resource for students. (Rogers, 1969) Behavioral views focus on extrinsic motivation in learning, where constructivist theorists suggest that motivation arises from the intrinsic sense of accomplishment through successful completion of tasks. Humanists theorize that motivation is based on the urge to satisfy basic needs and to grow as people mature. (Duchesne et al. 2013) Humanistic theories of education with their focus on self-evaluation and reflection can present difficulties in showing measurable outcomes that society expects from modern schools (Porter,2000) Behavioral methods that see the learning as observable changes in behavior allow for clear expectations and measurable outcomes. Constructivism directs educators to observe and reflect on children's current and incremental understandings
