Teacher education has always been shaped by a fundamental tension: what should a teacher know and be able to do? Different eras have answered this question in strikingly different ways, and the frameworks that emerged have left lasting marks on how teachers are recruited, trained, and evaluated. The history of teacher education is not a smooth progression but a series of competing visions—each responding to the limitations of earlier models while introducing new priorities and blind spots.
The first two frameworks to influence teacher education in the twentieth century were Behaviorism and Educational Essentialism. Though they emerged around the same time, they offered rival answers to the question of what makes a good teacher.
Behaviorism, rooted in the work of psychologists like John B. Watson and B.F. Skinner, treated teaching as a set of observable, measurable behaviors. In teacher education, this translated into an emphasis on behavioral objectives, direct instruction, and competency-based assessment. Programs trained teachers to deliver scripted lessons, reinforce correct responses, and manage classrooms through reward and punishment. The teacher was seen as a technician whose effectiveness could be quantified.
Educational Essentialism, by contrast, drew on the tradition of William C. Bagley and others who argued that the primary purpose of schooling was to transmit essential knowledge and cultural heritage. For teacher education, this meant a focus on subject-matter mastery. Teachers needed deep content knowledge and the authority to guide students through a prescribed curriculum. Where Behaviorism emphasized procedural skill, Essentialism emphasized disciplinary substance. These two frameworks coexisted uneasily in normal schools and colleges: Behaviorism shaped methods courses and observation checklists, while Essentialism shaped certification requirements in academic subjects.
By the mid-twentieth century, the limitations of both Behaviorism and Essentialism became apparent. Behaviorism’s neglect of mental processes—planning, decision-making, pedagogical reasoning—left teacher education without a language for the invisible work of teaching. Cognitivism emerged as a direct challenge to Behaviorism, drawing on cognitive psychology and the work of Jerome Bruner, David Ausubel, and later Lee Shulman.
Cognitivism insisted that teachers are not mere behavior managers but active thinkers who construct mental models of their students, their subject matter, and the learning process. In teacher education, this framework introduced concepts like pedagogical content knowledge—the special blend of content and pedagogy that expert teachers possess. Programs began to emphasize teacher cognition: how teachers plan lessons, make moment-to-moment decisions, and reflect on their own thinking. Unlike Behaviorism, which treated the mind as a black box, Cognitivism opened it up for study and development.
Constructivism shared Cognitivism’s focus on the active learner but went further by arguing that knowledge is not merely processed but actively constructed through experience and social interaction. Drawing on Piaget, Vygotsky, and Dewey, Constructivism reframed the teacher as a facilitator of meaning-making rather than a transmitter of knowledge. In teacher education, this meant that teachers should learn to design inquiry-based activities, scaffold student thinking, and attend to learners’ prior conceptions. Constructivism coexisted with Cognitivism in many programs, but its emphasis on social and experiential learning gave it a distinct identity.
A related but distinct framework, the Reflective Practitioner Model, emerged in the 1980s from Donald Schön’s critique of technical rationality. Schön argued that professional practice—including teaching—cannot be reduced to applying theory to problems. Instead, skilled practitioners engage in reflection-in-action, making intuitive judgments in the midst of complex situations. In teacher education, this model inspired reflective journals, action research, clinical supervision, and portfolios. It addressed a gap that Behaviorism and even early Cognitivism had left: the theory-practice divide. The Reflective Practitioner Model did not replace Constructivism; rather, it complemented it by giving teachers a method for learning from their own practice. Many programs integrated both, treating reflection as a way to construct professional knowledge.
By the 1970s, a growing awareness of social inequality prompted a new line of critique. Critical Pedagogy, rooted in Paulo Freire’s work and developed by Henry Giroux, Peter McLaren, and others, argued that teacher education had been politically neutral in ways that perpetuated oppression. It called on teachers to become transformative intellectuals who recognize and challenge systemic inequities in schooling. Critical Pedagogy contested the assumptions of both Behaviorist and Constructivist frameworks, insisting that teaching is never value-free. In teacher education, this meant incorporating discussions of power, ideology, and social justice into coursework and field experiences.
Culturally Relevant Pedagogy, introduced by Gloria Ladson-Billings in the 1990s, extended Critical Pedagogy’s commitments by specifying how teachers could build on students’ cultural knowledge as an asset rather than a deficit. Ladson-Billings identified three pillars: academic success, cultural competence, and critical consciousness. In teacher education, this framework pushed programs to prepare teachers who know their students’ cultural backgrounds, adapt instruction accordingly, and help students develop a critical awareness of society. Culturally Relevant Pedagogy narrowed Critical Pedagogy’s broad political critique into concrete classroom practices, making it more accessible to teacher educators while retaining its transformative intent.
The rise of the internet and digital technologies created conditions that earlier frameworks had not anticipated. Connectivism, proposed by George Siemens and Stephen Downes in the early 2000s, argued that learning in the digital age occurs across networks of people, tools, and information. Knowledge is distributed, and the ability to find and connect information becomes more important than possessing it. In teacher education, Connectivism influenced the design of online courses, personal learning networks, and professional development through social media. It did not displace Constructivism but rather supplemented it by describing how learning happens in networked environments where no single person holds all the knowledge. Critics have questioned whether Connectivism is a full-fledged learning theory or a pedagogical description, but its impact on teacher education is visible in the growing emphasis on digital literacy and continuous, informal professional learning.
Today, five frameworks remain active in teacher education: Constructivism, the Reflective Practitioner Model, Critical Pedagogy, Culturally Relevant Pedagogy, and Connectivism. They share several commitments: all emphasize active, contextualized learning; all reject the view of teaching as mere transmission; and all value reflection and adaptation. Yet significant disagreements persist. Constructivism and the Reflective Practitioner Model tend to focus on individual teacher growth, while Critical Pedagogy and Culturally Relevant Pedagogy insist that systemic change must be part of the agenda. Connectivism raises questions about whether traditional classroom-based preparation can keep pace with networked, just-in-time learning. Teacher education programs often blend these frameworks, but the tensions remain unresolved: content knowledge versus pedagogical flexibility, political critique versus practical skill, individual reflection versus collective action, and face-to-face community versus digital networks. These competing priorities ensure that teacher education will continue to evolve as new challenges—and new frameworks—emerge.
