Education reform: why change is slow and what scales

“Good innovations spread on merit.”

Every term below is defined in the words of education reform, primer C23 of understanding the context of education, and opens the primer at the slide where it is taught. 3 terms are also defined by another primer in the series; where the two differ, both wordings are given. The whole context glossary holds all of them together.

A
Adaptation

Changing a programme to fit the setting it lands in. Often treated as a failure of fidelity; in the few studies that measured it, adaptation was associated with better outcomes, not worse (Durlak & DuPre, 2008). Primer C11 covers it for curriculum.

C
Coherence

Fullan and Quinn’s term for the "[s]hared depth of understanding about the purpose and nature of the work" across a school or system. It is a state in people’s heads, not an alignment of documents (Fullan & Quinn, 2016, quoted in DeWitt, 2016).

Concerns-Based Adoption Model

Hall, Hord and colleagues' model, which treats adoption as something that happens to people rather than to organisations. Its two instruments are the stages of concern and levels of use (SEDL, n.d.-a, n.d.-b).

Core of educational practice

Elmore’s term for "how teachers understand the nature of knowledge and the student’s role in learning, and how these ideas about knowledge and learning are manifested in teaching and classwork", together with the structural arrangements that hold them in place (Elmore, 1996, p. 2).

D
De-implementation

"The systematic process of identifying, then reducing, replacing, or discontinuing low-value programs and practices, including organizational routines and policies" (Farmer et al., 2026). The counterpart to implementation, and far less often planned.

  • Farmer, S., Hudson, K., & Ward, C. (2026). Less is more: Leveraging the power of de-implementation to drive excellence in education (RTI Press Research Brief No. RB-0044-2603). RTI Press. doi
Depth

Coburn’s (2003) first dimension of scale: change in the substance of practice, including beliefs and norms, rather than in its surface features.

  • Elmore, R. F. (1996). Getting to scale with good educational practice. Harvard Educational Review, 66(1), 1–26. doi
Diffusion of innovations

Rogers’s account of how a new practice spreads through a population over time, through adopter categories from innovators to laggards, and according to how an innovation is perceived on attributes such as relative advantage, compatibility, complexity, trialability and observability (Rogers, 2003). The craft series’ guide 19, Adoption and change in schools, covers it in detail.

  • Rogers, E. M. (2003). Diffusion of innovations (5th ed.). Free Press.
Disruptive innovation

Christensen's theory, applied to schooling with a forecast that by 2019 about half of high school courses would be delivered online. That did not happen, and it has been widely questioned (Christensen et al., 2008).

C02 The theory that a new model first serves people the existing system does not, then improves until it displaces the old one; Christensen, Horn and Johnson applied it to schools (Christensen et al., 2008).

E
Educational change

The general field concerned with how practice in schools and systems alters, why most attempts fail, and what distinguishes the ones that last.

Fidelity

How closely delivery matches the design. One of eight aspects of implementation, alongside dosage, quality, participant responsiveness, programme differentiation, monitoring of comparison conditions, reach and adaptation (Durlak & DuPre, 2008).

First- and second-order change

First-order change makes the existing arrangement work better; second-order change alters the arrangement itself. The distinction comes from Cuban (1988), and explains why most reforms that survive are of the first kind.

Grammar of schooling

"The regular structures and rules that organize the work of instruction", such as age grades, periods and subjects (Tyack & Tobin, 1994, p. 454). Primer C02 covers it in depth.

Hybrid

What usually results when an ambitious reform meets an existing classroom: some new language and materials over a largely undisturbed core (Cuban, 1984, reported in Elmore, 1996).

I
Implementation drivers

The supports that make new practice usable: selection, training, coaching, performance assessment, data systems, facilitative administration and systems intervention. Fixsen et al. (2005) call them core implementation components and note that they compensate for one another.

Implementation science

The study of what it takes to put an evidence-based practice into routine use, and of why the same programme produces different results in different places (Fixsen et al., 2005; Durlak & DuPre, 2008).

Implementation stages

The stages a change passes through: exploration, installation, initial implementation and full implementation. They are not linear, and fully operationalising a practice can take two to four years (National Implementation Research Network, 2015).

Improvement science

A discipline that treats variation between sites as the object of study, works in short cycles close to the practice, and measures the process as well as the outcome (Bryk et al., 2015).

Initiative overload

The condition of a school running more initiatives than it has attention for, so that each is implemented shallowly. Fullan and Quinn describe coherence as "so difficult to accomplish under conditions of overload, fragmentation and policy churn" (quoted in DeWitt, 2016).

Innovation

A practice, product or arrangement that is new to the people adopting it, whether or not it is new in the world. Newness to the adopter is what creates the implementation problem.

  • Elmore, R. F. (1996). Getting to scale with good educational practice. Harvard Educational Review, 66(1), 1–26. doi
Innovation fatigue

The loss of energy and credibility that follows repeated cycles of announcement and abandonment. It is what makes the next good idea harder to introduce than the last one.

Kotter's eight-step change model

A popular change model that "appears to derive its popularity more from its direct and usable format than from any scientific consensus on the results"; best used as organised experience (Appelbaum et al., 2012).

Lighthouse and pilot schools

Schools chosen to run a change first, either to test it (pilot) or to demonstrate it to others (lighthouse). Both give better-than-average conditions, which is what makes them useful for learning and misleading for forecasting.

Networked improvement community

A group of sites working on the same specific problem with shared measures, so that what one learns is usable by the others. Proposed as an alternative to the usual organisation of educational research (Bryk et al., 2011).

Pilot-to-scale

The move from a small, supported trial to system-wide use. Effects normally fall in the move: in teacher coaching, programmes with 100 teachers or more showed effects one-third to one-half the size of smaller ones (Kraft & Blazar, 2018).

S
Scale

Not only how many sites have a reform, but how deeply practice has changed, whether it survives, how far it has spread, and whether ownership has shifted from the sponsor to the school (Coburn, 2003).

  • Coburn, C. E. (2003). Rethinking scale: Moving beyond numbers to deep and lasting change. Educational Researcher, 32(6), 3–12. doi
  • Elmore, R. F. (1996). Getting to scale with good educational practice. Harvard Educational Review, 66(1), 1–26. doi
Shift in reform ownership

Coburn’s fourth dimension: the point at which a change stops being the sponsor’s project and becomes the school’s own practice. Without it, sustainability depends on continued external attention.

  • Coburn, C. E. (2003). Rethinking scale: Moving beyond numbers to deep and lasting change. Educational Researcher, 32(6), 3–12. doi
Spread

Coburn's third dimension of scale: how widely a reform travels. It is countable, cheap to report and the least informative of the four (Coburn, 2003).

  • Coburn, C. E. (2003). Rethinking scale: Moving beyond numbers to deep and lasting change. Educational Researcher, 32(6), 3–12. doi
Stages of concern

The first CBAM instrument: seven categories of concern about an innovation, running from unconcerned and informational through personal and management to consequence, collaboration and refocusing (SEDL, n.d.-a).

  • Hall, G. E., & Hord, S. M. (2019). Implementing change: Patterns, principles, and potholes (5th ed.). Pearson.
  • SEDL. (n.d.-a). Stages of Concern, a dimension of the Concerns-Based Adoption Model (CBAM). Retrieved September 18, 2026, from sedl.org
Sustainability

Coburn’s second dimension of scale: whether a change persists once the funding, the champion or the attention moves on.

System leadership

Leadership exercised beyond one’s own school. "System leaders are those Heads or Principals who are willing to shoulder system wide roles in order to support the improvement of other schools as well as their own" (Hopkins & Harris, 2023).

Teacher coaching

Follow-up support in the classroom where the work happens. Across 60 causal studies it moved instruction by about half a standard deviation, with effects thinning as programmes grow (Kraft et al., 2018).

Wrong drivers

Fullan's term for what systems repeatedly pick: accountability rather than capacity building, individual quality rather than group solutions, technology rather than instruction, and fragmented rather than systemic strategies (Fullan, 2011).
