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. In addition, reviewing the entire presentation at its end, summarizing main points, is particularly effective. It is also effective to have students review what has been presented through the active learning techniques discussed previously. These reviews, carefully presented, demonstrably increase student learning.
