Skimming and Scanning
Short Answer
Skimming is for understanding the gist (structure, claims, key points). Scanning is for finding a specific detail (a date, name, definition, or step). Use them to match your reading speed to your purpose instead of reading everything at the same pace.
How to Skim
1) Read headings:{" "} Use the table of contents, headings, and subheadings to see the map.
2) Hunt topic sentences:{" "} First sentences of paragraphs often carry the main idea.
3) Capture keywords:{" "} Bold terms, lists, and summaries are high-signal.
How to Scan
Decide what you’re looking for (a number, name, concept). Then move your eyes quickly down the page, letting that target “pop” out. You’re not reading sentences; you’re searching for a match.
