This document outlines the "teaching as inquiry" framework for improving teaching practice. It discusses using inquiry to develop understandings of the "Thinking Competency" as an example. The framework involves three parts: discovering areas for focus through establishing student baselines; designing evidence-based strategies to help students learn; and delivering teaching to achieve outcomes while monitoring implications through various assessments. Teachers articulate beliefs, adopt an inquiry stance, ask questions, and seek and analyze multiple data sources for evidence of impact on learning. Findings are shared and used to continually improve competence through an ongoing reflective cycle. The goal is improving student learning outcomes through questioning practice and using research-based evidence to strengthen teaching approaches.
