This PowerPoint presentation provides guidance on writing effective summaries of research sources. It explains that a summary should reduce the original source down to the main idea and major evidence in 3 sentences or less. The presentation instructs students to identify the central topic of the source and write one sentence expressing the main point, followed by 1-2 additional sentences summarizing the key supporting points or evidence. It advises avoiding direct quotes, opinions, and statements of what a source says, instead using objective third-person language. Students are provided examples of summaries and assigned practice summarizing specific sources to be completed as homework.
