By Don Allen I wrote the ‘ Theory of Corners ’ as a diagnostic tool. This is what it says about the video. Note: The Theory of Corners suggests that unless the underlying organizational "corner" — the specific institutional habit driving the poor outcomes — is dismantled, the cycle of "budget cuts" and "instability" (1:40-1:47) will likely persist despite the proposed structural shifts. Background The "Theory of Corners" developed by Dr. Don Allen is a diagnostic model designed to analyze high-functioning but low-outcome learning organizations . It serves as a framework for identifying why institutions, despite having resources and structure, may fail to meet their desired goals for students. Application Applying this lens to the Minneapolis Public Schools ( MPS ) transformation message (0:00-4:07), one could critique the district's current approach as follows: Findings Structural Inefficiency : Dr. Sayles-Adams notes that the district is...

Dr. Don Allen is an educator and administrator known for his work in curriculum development and instruction. In secondary education, his frameworks emphasize building strong study skills, time management, and systematic note-taking for high schoolers (Grades 9–12) to transition successfully into higher education and career paths. When implementing targeted note-taking instruction for grades 9 through 12, the focus shifts from simple compliance (copying words from the board) to active cognitive processing.

Students split the page into a note-taking column, a left-hand "cue" or question column, and a bottom summary block. The Outlining Method : Best for highly structured, linear subjects (e.g., History or Literature). It te...
