When a person pays attention to a lecture, it becomes an important skill to "summarize important points." This means that the information you will be taking down should contain all the important information with the least amount of words. Writing down everything Lisa hears during the lectures will make her<em> unfocused and tired at the same time.</em> It also takes a lot of time!
Remember that Lisa is not only taking an online course but is also taking some lectures with traditional teaching methods in school. So, this means that<u> she cannot pause the lecture because not all lectures are conducted online.</u> Audio recording every lecture is time-consuming because playing the audio back means attending the lecture again.
So, this makes summarizing important points as the best way for Lisa to take down notes.
First it is important to take note of where this information is coming from. The speaker is a representative of the national energy company and therefore will likely not speak poorly of the results of the natural gas project. Then it would be important to fact check his or her claims against other sources and evidence.
