Supposedly Direct Instruction works...

According to this book, Direct Instruction works, at least thats what Marginal Revolution says:

Ayres argues that large experimental studies have shown that the teaching method which works best is Direct Instruction (here and here are two non-academic discussions which summarizes much of the same academic evidence discussed in Ayres). In Direct Instruction the teacher follows a script, a carefully designed and evaluated script. As Ayres notes this is key:

DI is scalable. Its success isn't contingent on the personality of some uber-teacher....You don't need to be a genius to be an effective DI teacher. DI can be implemented in dozens upon dozens of classrooms with just ordinary teachers. You just need to be able to follow the script.

Contrary to what you might think, the data also show that DI does not impede creativity or self-esteem. The education establishment, however, hates DI because it is a threat to the power and prestige of teaching, they prefer the model of teacher as hero. As Ayres says "The education establishment is wedded to its pet theories regardless of what the evidence says." As a result they have fought it tooth and nail so that "Direct Instruction, the oldest and most validated program, has captured only a little more than 1 percent of the grade-school market."

Who would of thought...

Update: Go read the comments, pretty interesting, with the usual character showing up to enlighten the idiots.
