Systems thinking reminds us that individual parts are often less critical to an outcome than the relationships between those parts.
The same principle applies to teacher development.
Each competency matters. Its full value, however, depends partly on how it interacts with other competencies.
Consider success criteria. Requiring teachers to develop and communicate clear success criteria may be a worthwhile focus. But are teachers also shown how success criteria can:
• strengthen instructional (planning)
• guide the chunking and sequencing of content (instruction)
• sharpen formative assessment (reflection)
• inform scaffolding (instruction)
• give students greater clarity and ownership of their learning (conditions for learning)
Without these connections, success criteria can become an isolated requirement—a task to complete rather than a competency that influences multiple dimensions of effective practice.
A systems-oriented approach does not eliminate focused improvement. It places each area of focus within a coherent developmental progression.
Leaders consider how new learning connects to what teachers already know, which supporting competencies are required, which established practices must remain active, and how growth in one area can strengthen performance in another.
The focus then becomes part of an expanding vision of effective practice—not simply the next mole to strike in the game of Educational Whack-A-Mole. Our goal is to improve the relationship between the key parts: planning, instruction, reflection, and the conditions for learning.
