π Skimming vs. Scanning: Decoding Information Retrieval
Skimming and scanning are both reading techniques used to quickly extract information from a text, but they serve different purposes. Skimming helps you understand the main ideas, while scanning helps you locate specific details.
π Definition of Skimming
Skimming involves quickly reading through a text to get a general overview of the content. It's like taking a bird's-eye view to understand the main topics and arguments without focusing on every single detail.
π Definition of Scanning
Scanning, on the other hand, is about searching for specific information within a text. You know exactly what you're looking for (e.g., a name, a date, a keyword) and move your eyes rapidly across the page until you find it.
