Skim reading is a technique used to quickly gather the main ideas of a text without focusing on every word. This method involves glancing through headings, subheadings, and highlighted text to identify key points. It is particularly useful for reviewing large amounts of information, such as articles or reports, when time is limited. When skim reading, readers often look for keywords and phrases that stand out, allowing them to understand the overall message. This approach is beneficial for students and professionals alike, as it helps in efficiently processing information and deciding what to read in detail later.
