Are Teachers Change Agents?

Today I read Robert Pondiscio’s piece, Public Schools Are Molds Not Platforms, and he’s right about something fundamental: public schools are not platforms for personal expression or ideological performance.

Direct Instruction Embodies the Science of Learning

In one of my more popular posts, I argued that we need to do better than just nod politely at Direct Instruction (DI).

Direct Instruction Motivation, Part 3: Success, Not Struggle

Direct Instruction Motivation, Part 3: Success, Not Struggle

This series explores a rarely discussed strength of direct instruction: its power to motivate students. While critics often paint explicit teaching as boring or uninspiring, the truth is that its structure, pace, and design motivate kids better than any other system. There is a certain romance in education about the idea of “Productive Struggle.” The notion goes … Continue reading Direct Instruction Motivation, Part 3: Success, Not Struggle

The Truth About Lesson Planning 

The first truth about lesson planning is a paradox: In a perfect world, it wouldn’t even exist. Designing curriculum and instruction is its own science, and a difficult one at that. When well-designed programs (e.g., Direct Instruction) are in place, the heavy lifting of content analysis, sequencing and integrating of concepts, and field-testing of lessons … Continue reading The Truth About Lesson Planning
