An Examination of Teacher Leaders and a Shared Leadership Approach: Contributions to System Improvement in a School District
Bibliographic record
Abstract
There is an emerging body of evidence that recognises the significant role informal teacher leaders play in the pursuit of school and system improvement. This article reports the results of a multi-phase, design-based research study conducted with teacher leaders, assistant principals and principals who participated in a two-year design-based professional learning initiative with the goal of building capacity for instructional leadership and system improvement. The question guiding the study was: In what ways do teacher leaders contribute to system improvement? Three dimensions of focus associated with high-performing systems emerged from the data in connection to the investment in professional capital that contributed to system improvement: (a) enhancing the quality of teaching and learning for school and district improvement, (b) preserving continuous design-based professional learning opportunities, and (c) ensuring opportunities for collaborative learning alongside colleagues and the development of a network of teacher leaders with a shared purpose. Teacher leaders are informal leaders and important members of an instructional leadership team contributing to school and district improvement.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
