Note taking is the act of recording information from many different sources in order to review or remember later. Note taking doesn't mean writing down everything you read or hear but to make brief bullet points or summarize in your own words the key information from a source.
Why do we take notes:
To recall information for later review
To help you better understand information and increase learning
To rewrite information in your own words to help with maintaining essential information
To help you to stay focus and pay attention to the information you are learning
To find out what you know and what you need to continue to review
to organize information in a structured way
When you use the charting note-taking method, you divide you paper into columns and organize information into different categories or topics. Each column will have its own title or label. You enter notes under each related column.
