Generations of Metaphors: From Broad Horizons to Intellectual Renovation

The metaphors teachers use to describe their work come and go, but they leave a mark on how learning is understood, argues educator and writer Zachary Michael Jack. In a reflective essay, he traces several decades of shifting analogies within higher education, showing how each generation of professors sought a new image to capture the complexities of teaching.

In the 1990s, a common refrain was that a university education would “broaden horizons” or “expand minds”—a metaphor that especially resonated with rural, first-generation students. By the early 2000s, the language had changed: “leveling the playing field” became a favoured expression, implying that instructors were agents of equity. But that image, too, faded as critics questioned how a single semester of pot-throwing or plant genetics could truly deliver such levelling.

More recently, Jack recalls a senior colleague who described their work as helping students “rearrange their intellectual furniture.” Borrowed from the makeover culture of home-flipping shows, the analogy felt efficient and modest: professors were not discarding students’ existing knowledge but polishing it. Yet, Jack notes, the metaphor also carried uncomfortable implications—framing learning as a quick, surface-level renovation, driven by the desire for short-term results.

What the Shifts in Teaching Language Reveal About Higher Ed

The Metaphor as a Mirror of Institutional Priorities

Each shift in language did not emerge from nowhere. The “broadening horizons” metaphor aligned with a period when universities marketed the intangible rewards of a liberal arts education—personal growth, curiosity, worldliness. As public scepticism about the return on investment of a degree grew, metaphors became more transactional. “Leveling the playing field” promised social impact, while “intellectual furniture” offered a tangible, almost domestic result. These are not neutral word choices; they signal what institutions believe their stakeholders—students, parents, legislators—want to hear.

When a Clean Renovation Oversimplifies Learning

Jack’s unease with the renovation metaphor points to a genuine tension. If teaching is framed as flipping mental furniture, it suggests that the learner’s existing ideas are outdated décor, to be rearranged quickly and profitably. That image clashes with the slower, disruptive work of genuine intellectual transformation. For a sector already under pressure to prove its worth in concrete terms, the risk is that metaphors promising clean, semester-length makeovers set expectations that neither professors nor students can reliably meet.

The Audience Has Expanded—and So Have the Demands on Language

Jack observes that teaching metaphors must now satisfy not just students but also “parents and pundits seeking reassurance in the most concrete terms.” This is a commercial as well as a pedagogical reality. Public metaphors are part of the education sector’s defensive messaging in an era of rising tuition, student debt and political scrutiny. A misjudged analogy can undermine trust, while a resonant one can help a programme attract applicants and support.
