Multi-Sensory Direct Instruction The true test of multi-sensory direct instruction is whether or not all four language-learning avenues—saying, hearing, writing, and seeing—are used at the same time.  The curriculum must guide the teacher to guide the student to connect his four language-learning avenues.  This is the historically tried and true definition of multi-sensory direct instruction.  It also may be called full-spectrum neurological response instruction or the “recite as you write” teaching method our forefathers used.
