How to Teach — Context and Discussion

The Social Purpose of Education

The authors assert that schools exist “for the group of which he is a member,” not for the isolated individual. This collectivist premise is not merely stated in the preface but actively shapes the chapters. In the discussion of play, for example, they note that the “gang spirit” from ages ten to twelve influences outdoor games and adventures, and that group interest widens in adolescence. The moral-social conduct chapter (XI) explicitly ties individual behavior to group welfare. The authors do not treat social purpose as a separate topic; it is the lens through which all teaching methods are evaluated. Even the measurement of achievements is justified by the need to determine “changes which are brought to pass in the children” for the benefit of society. This consistent emphasis distinguishes the book from purely individualistic pedagogical texts of the same period.

Play as a Developmental Sequence

The chapter on play offers one of the most concrete applications of the authors’ psychological framework. They describe play tendencies as emerging in rough age-based stages: sensory and imitative play from four to seven; individual competition from seven to ten; the gang spirit from ten to twelve or thirteen; and emotional, intellectual play in early adolescence. Crucially, they hedge these generalizations with a long list of modifying factors: “readiness of other tracts to function; past experience and habits; the stimulus provided by the present situation; absence of competing stimuli; sex, health, fatigue, tradition.” The analysis of a four-year-old playing with a doll is particularly detailed, breaking down the activity into nursing instinct, manipulation, physical activity, imitation, curiosity, and imagination. For a nine-year-old, the same doll play becomes organized and practical—making clothes or furniture. This progression illustrates the authors’ method: they dissect a common classroom observation into its psychological components, then link each to a developmental stage.

Plain Language and Scientific Grounding

The authors explicitly state they wrote “in language as free from technical terms as is possible.” Yet the book is not a simple how-to manual; it repeatedly cites “investigations and researches in the fields of psychology and education.” The preface promises that each principle will be tied to “the scientific inquiry upon which it is based.” In the play chapter, for instance, the age-stage summary is described as “by no means complete” but as indicating “prominent tendencies.” The authors balance authority with caution, acknowledging that “the readiness of nerve tracts to function” depends on multiple factors. This dual commitment—accessible prose plus empirical grounding—makes the book a hybrid: part textbook, part research summary. The result is a work that aims to equip teachers with both theoretical understanding and practical guidance, without sacrificing one for the other.

Readers will find that the book’s value lies less in its specific prescriptions (some of which reflect 1917 educational norms) than in its method of reasoning from psychological principles to classroom practice. The authors consistently ask why a technique works, not just how to apply it. Pay attention to the way they qualify their own generalizations—these hedges reveal a sophisticated awareness of individual differences and contextual factors. The chapters on habit formation, memorization, and transfer of training are particularly dense with such nuance. For a modern educator, the book offers a historical case study in evidence-based pedagogy, as well as a reminder that many core questions about teaching and learning have been debated for over a century.
