Traditionally, technical communication courses have focused on the written transmission of information. Recent research, however, indicates that oral presentation and interpersonal exchange are as important as writing to on-the-job communication.

Based on these insights, it also suggests some new strategies for teaching technical communication — strategies that place an equal emphasis on writing, oral presentation, and interpersonal communication.
