Our school uses the Direct Instruction (DI) Method to teach all subjects, particularly Reading and Math. DI is a very fast-paced, scripted method we teachers use to keep the students more focused and engaged.
For about an hour every day in both Reading and Math, we divide into small groups of 4-12 students who are all about the same level. We follow a script and they follow along with us. Repetition is a key ingredient on both the teachers' and students' parts. Classroom response is required and we occasionally fire questions at them individually to keep them on their toes and see if they are listening; they receive immediate feedback. We go over and over the material until we can see everybody understands it. Approximately 1/3 of the classtime is Direct Instruction, 1/3 practice problems on the board, and the final 1/3 is for individual seatwork. Anything they don't finish becomes their homework.
As the students attain mastery at their level they move on to another level until they reach a point where they need little teacher interaction and intervention. This method works magnificently as our students score in the upper 90's percentile on the state CRT tests in all subjects, particularly Reading and Math.
