Skimming involves quickly glancing over a text to get a general sense of its content, focusing on headings, keywords, and subheadings. It is useful for quickly determining the main ideas. Scanning, on the other hand, is a more targeted search for specific information, involving moving your eyes quickly over the text to locate particular details or keywords without reading the entire content.
Key Takeaways
- Skimming is a reading technique where the reader quickly goes through a text to grasp its main ideas or general overview without focusing on details.
- Scanning is a reading method where the reader searches for specific information within a text, such as keywords, facts, or figures, without reading the entire content.
- Skimming aims to quickly understand the overall content while scanning targets specific details or information within the text.
Skimming vs Scanning
The difference between Skimming and Scanning is that both are reading techniques but used for different purposes. Skimming is reading to get a surface-level understanding of the concept. At the same time, scanning is a reading method used to look for specific information.
Skimming is a fast reading technique to know the text’s plot quickly. With less time, readers can read more text using the skimming process.
Scanning is a reading technique used to look for specific information or a particular word in context. When we want to look for a cricket match score in the newspaper, find a specific name or phone number, the price of your favourite dish on the menu, and so on.
