WHAT IS INSIDE

One improvement project. Three kinds of evidence.

A fully synthetic ninth-grade team tests three PDSA cycles to raise on-time arrival and reading growth. The workflow analyzes the weekly measure, the focal students, and the coded feedback together.

01

Run chart

A baseline median extended forward, with shift, trend, and crossing rules and signals marked on the chart.

02

Control charts

A p-chart for a weekly proportion with varying enrollment and individuals/moving-range charts for a continuous measure.

03

Small-sample pre/post change

Mean change with t and bootstrap intervals, the Wilcoxon test, dz and dav, and the share reaching a meaningful gain.

04

Ordinal items and regression to the mean

Direction-of-change summaries for Likert items and a check on how much of the gain reflects low starting scores.

05

Cycle learning

Coded feedback themes by cycle and a Plan–Do–Study–Act summary joining change ideas, predictions, signals, and decisions.

06

Write-up

Dissertation-in-practice results text and a SQUIRE 2.0–informed reporting checklist.

DESIGNED FOR DISSERTATIONS IN PRACTICE

Improvement evidence, reported with care.

This workflow is useful when:

  • Your EdD project tests change ideas through PDSA or action-research cycles.
  • You track an outcome or process measure weekly or by cycle.
  • You measure a small group of students or staff before and after.
  • You need to connect feedback from each cycle to the decision the team made.

It supports local learning and improvement decisions. Without a comparison group, changes cannot be attributed to the change ideas alone; the report names the main threats. Qualitative coding is done outside R.
