How did psychology become important in teacher training?

Psychology became a cornerstone of teacher training in the late 19th and early 20th centuries as educators sought a "scientific" basis for pedagogical principles. Prior to 1890, teacher preparation relied heavily on general mental and moral philosophy, but the crystallization of psychology as a distinct discipline allowed for a more structured approach to understanding the learning process.1

Key developments that integrated psychology into teacher education include:

• Scientific Pedagogy: Figures like Edward L. Thorndike argued that education should be treated as a science, with psychology serving as its foundation—much like botany and chemistry support agriculture. His formulation of learning laws became a staple in training programs.1
• Child Development: Influenced by G. Stanley Hall and evolutionary ideas, teacher training began to emphasize the unique developmental needs and stages of childhood.1
• Redefining Relationships: Psychologists and philosophers helped redefine the teacher-pupil relationship by highlighting the importance of a child’s individual interests, motivations, and capacities for learning.12
• Practical Application: The rise of educational psychology introduced methods for measuring abilities, diagnosing learning problems, and organizing classrooms through techniques like the "project method".12
