Short Summary
Main recommendation: Use skimming to quickly grasp what a text is about, and scanning to locate specific information such as names, figures, or dates, since together they make reading faster without missing what matters. The lecturer explains that skimming is for getting the general idea, while scanning is for hunting a known target in the text.
Key Points
- Skimming means reading quickly for the gist, taking only the basic information you need without detailed reading, and deciding whether to keep reading based on what you find.
- Scanning means moving your eyes (or finger) rapidly over a page and stopping as soon as you catch the word or phrase you are looking for, since you already know what you need.
- The core difference: skimming gives you an idea of the whole text without knowing details beforehand, while scanning starts with a known target and searches for it.
- Both skills save time and are useful for newspapers, messages, emails, exam revision when time is short, and quickly finding answers to comprehension questions.
Details Worth Noting
- Concrete instructions: For skimming, (1) read the title; (2) read the introduction, especially the first sentence of the first paragraph; (3) look at diagrams, pictures, or graphs; (4) read the subheadings. If these fit your needs, continue reading; if not, move on. Also read bold words and the first line of each paragraph. For scanning, first turn your question into key words or names (for example "family" and "alligators"), then move your eyes or finger quickly over the text and stop as soon as you find those words, which are usually the answer. Practice both skills with books and columns to strengthen them.
- The lecturer's alligator example shows the method: the title and picture establish the topic, the subheadings "Family," "Types," and "Life" guide the reading, and specific questions about families, Chinese versus American alligators, and alligators versus crocodiles are answered by scanning for those exact words.
- Skimming's limitation is that it cannot guarantee you have captured every important point, because you are not reading the whole text.
- Skimming is especially useful before entering a new textbook chapter or long article, and when only a few days remain before exams, for reviewing difficult or important sections.
- Scanning suits finding a friend's phone number in a directory, last night's football scores, a player's schedule, or a favorite dish on a restaurant menu.
Bottom Line
Combine the two: skim first to decide whether a text is worth your time, then scan for the specific facts you need, which lets you read faster without missing what matters.
