33、: Note-taking 2,Understanding Lectures: Note-taking 2,When giving a lecture, the speaker usually presents an idea and then develops it. Noticing this structure and other signals, one can better understand the lecture and more easily choose the most appropriate style of notes for the lecture. By sele
34、ctively recording key points, one can clearly organize the main idea, as well as all the facts, examples, and supporting information used to develop that idea.,Unit 6 Part II,Popular note-taking formats include: two-column table spidergram ( mind-mapping) diagram/mind-mapping two-column table table
35、timeline flow chart outlining (headings and notes),Unit 6 Part II,advantages and disadvantages cause and effect classification and definition comparison and contrast facts and figures sequence of events stages of a process question and answer,The following is an illustration of the column-style form
36、at. It helps organize information into two different columns. First, draw a vertical line. The left column should be drawn 1/3 the distance from the left side of the page, and the right column should be 2/3 from the right side of the page. Next, label the left column “Main Ideas”, and the right colu
37、mn “Notes”. In this way, the main content is arranged orderly and clearly.,Unit 6 Part II,For example:,Unit 6 Part II,Another popular format is the diagram format. First, draw a circle in the center of the page. Inside that circle, write the topic of the lecture (e.g. Are earthquakes really on the i
38、ncrease?). Next, draw a line branching out from the center circle. Then write the first section, or main idea, of the lecture (for example, reasons for the increase). Draw more circles branching out from that line containing important details which describe that main idea. A more formal version of t
39、his format is the flowchart（流程图）.,Unit 6 Part II,Unit 6 Part II,The outline format is another popular choice. To organize notes in this way, first, list the major concepts as the top-level points (I, II, III). Then list the main ideas (A, B, C) as subordinate points. After that, place the aspects of
40、 the main idea in the order of 1., 2., 3. In this format, use indention（缩进）and listing to ensure that these marks are clearly subordinate（附属）ideas. Traditionally, with each additional level, one alternates between numbers and letters (with the former, also between Roman numerals and Arabic numbers),
41、 and descends from capital letters to lowercase letters.,Unit 6 Part II,For example: I Earthquakes on the rise? A. Reasons for the increase 1. a. i. ii. iii. b. 2. a. 3. a. i.,Unit 6 Part II,B. 1. 2. 3. II. A. B. The best way to take good notes depends partially on the specific learning style of eac
42、h student. Linear（线性的）learners will likely take column-style notes, while visual learners may prefer the diagram method. The latter is also effective for students who have a difficult time staying focused in class. Students should experiment to find the format that works best for them.,Unit 6 Part I
