Differentiated instruction must be carefully planned for when designing lessons for students

based on your knowledge and research information provide a brief example of a lesson that has not been planned for differentiation and your recommendations for how this lesson can be modified to include the principals of differentiation.

A lecture on how to do a chemestry experiment could also be done as a written procedure, a computer based hyper-text document, a slide show presentation or a video. All of those alternatives would be a more efficient means of teaching than a lecture because they don't require assembling people together and can be learned at the student's pace instead of the lecturer's.

The down side to "work at your own pace" is that students can get on EHelp rather that do their own thinking.
