Stress important points during explanations. Lecturers need to draw students' attention to the material that is most crucial in the presentation being given. It is particularly important to stress anticipated difficult points, because detailed, redundant explanations for difficult concepts can lead to increased student learning. Provide for brief pauses at appropriate times during the lecture. As a result of rapid teacher-talk students often are not given adequate time to process information.
Research suggests that the amount of notes a student takes correlates positively with achievement.
Yet, while teachers talks at a rate of 120 - 240 words per minute, many students are only capable of taking notes at a rate of 20 words per minute. Eliminate additional unexplained content nonessential to current explanation. Research shows that presenting less is more effective. Review information frequently. Periodically during a presentation, but particularly at the end of difficult material, lecturers should review and summarize the main points.
