Is an effective student strategy to summarize the main idea in their own words. The summary should be 25 words or less. When proofreading, students should make certain all the highlights of the issue are covered. Then the summary is reduce to 20 words. Another look should allow further reduction of the passage to no more than 15 words. The main idea will remain; hence the name the "gist".
This is a study tool that my students should do after each chapter. I will assign a summary of each of the textbook's chapters as a participation grade.
