John Dewey (; October 20, 1859 - June 1, 1952) was an American philosopher, psychologist, Georgist, and educational reformer whose ideas have been influential in education and social reform. Dewey is one of the primary figures associated with the philosophy of pragmatism and is considered one of the fathers of functional psychology. A Review of General Psychology survey, published in 2002, ranked Dewey as the 93rd most cited psychologist of the 20th century. A well-known public intellectual, he was also a major voice of progressive education and liberalism.
Dewey believed that the successful classroom teacher possesses a passion for knowledge and an intellectual curiosity in the materials and methods they teach. For Dewey, this propensity is an inherent curiosity and love for learning that differs from one's ability to acquire, recite and reproduce textbook knowledge. "No one," according to Dewey, "can be really successful in performing the duties and meeting these demands [of teaching] who does not retain [her] intellectual curiosity intact throughout [her] entire career" (Dewey, APT, 2010, p. 34). According to Dewey, it is not that the "teacher ought to strive to be a high-class scholar in all the subjects he or she has to teach," rather, "a teacher ought to have an unusual love and aptitude in some one subject: history, mathematics, literature, science, a fine art, or whatever" (Dewey, APT, 2010, p. 35). The classroom teacher does not have to be a scholar in all subjects; rather, a genuine love in one will elicit a feel for genuine information and insight in all subjects taught. In addition to this propensity for study into the subjects taught, the classroom teacher "is possessed by a recognition of the responsibility for the constant study of school room work, the constant study of children, of methods, of subject matter in its various adaptations to pupils" (Dewey, PST, 2010, p. 37). For Dewey, this desire for the lifelong pursuit of learning is inherent in other professions (e.g. the architectural, legal and medical fields; Dewey, 1904 & Dewey, PST, 2010), and has particular importance for the field of teaching. As Dewey notes, "this further study is not a side line but something which fits directly into the demands and opportunities of the vocation" (Dewey, APT, 2010, p. 34). According to Dewey, this propensity and passion for intellectual growth in the profession must be accompanied by a natural desire to communicate one's knowledge with others. "There are scholars who have [the knowledge] in a marked degree but who lack enthusiasm for imparting it. To the 'natural born' teacher learning is incomplete unless it is shared" (Dewey, APT, 2010, p. 35). For Dewey, it is not enough for the classroom teacher to be a lifelong learner of the techniques and subject-matter of education; she must aspire to share what she knows with others in her learning community.
