Effective oral presentation of scientific and technical information

Prepared for engineering and science students, this article stresses the preparation for the talk, the judicious use of notes, and the effective use of visual aids. To deliver a talk effectively, students must know the elements of delivery: ample projection of the voice, natural movements, relevant gestures, and eye contact. Furthermore, students should be aware of such errors as the following: poor board work, lack of movement and enthusiasm, overuse of notes, monotonous voice, poor eye contact, repetition, and the use of slang and colloquialisms. To make effective oral presentations, one should develop an extensive vocabulary and should evaluate his delivery.
