Final answer:
Note-taking can be done using diagrammatic strategies such as graphic organizers, which are useful for visual mapping of information, or non-diagrammatic strategies like content notes, which focus on listing key ideas and phrases.
Step-by-step explanation:
Two strategies that can be used to take notes include diagrammatic and non-diagrammatic formats. The diagrammatic strategy involves using graphic organizers, such as tables and charts, to visually map out information. These can include organizers like Figure 18.15 or Table 7.4, which help in organizing various modes of information like linguistic, visual, audio, spatial, and gestural, and assess their impact on the audience.
On the other hand, the non-diagrammatic strategy focuses on written notes, commonly in a list or linear form. This method is exemplified by taking content notes during interviews or lectures, where the note-taker records key ideas and exact quotes that may be useful later.
