Identifying Main Idea and Details with a textbook sample

Identifying Main Idea and Details using a textbook sample

I can analyze how main ideas of a text are shaped, refined, and complicated by specific details. [RL.11-CCR.2]

I can analyze how main ideas of a text are shaped and complicated by specific details.

• I can identify the main idea.

• I can identify supportive details.

• A main idea can be implicit.

• A main idea can be explicit.

How important is the main idea?

The main idea is the central point that a writer makes. It summarizes the important  details within a passage.

Sometimes the main idea is stated explicitly, and other times is implied.

Where can you find the explicit main idea?

• The main idea can be anywhere in the passage.

• However, most of the time, the main idea is at the beginning of the passage.

  
  

• In college textbooks, the main idea is explicitly stated only about 50% of the time.

Explicit means obvious, implicit means subtle.

Well what does subtle mean?

It means, "difficult to detect, delicate, achieved in a quiet way that does not attract attention to itself and is therefore good or smart"

Finally! You know what you want to become: an EMT (emergency medical tech). It's the first day of class, and you are assigned to read chapter one in your textbook titled, Responding to Emergencies: Comprehensive First Aid/CPR/AED. The following slides contain two pages from your book.

Multiple Choice

By securing the airway you provide an open pathway for air to move into and out of the body. However, a patient's airway does not guarantee that the air will move in adequate volumes to support life. Recall that breathing accomplishes two essential functions: It brings oxygen into the body and it eliminates carbon dioxide. Although your body will tolerate the buildup of carbon dioxide longer that it will tolerate a lack of oxygen, both functions are essential to support life.

Proper airway management must always be paired with the assessment of adequate breathing to ensure that both critical functions are occurring. If you determine that the patient’s breathing is not meeting the body’s needs, then you must take immediate corrective action. A thorough primary assessment focuses on a rapid evaluation of both airway and breathing and identifies immediate life threats associated with the airway and the respiratory system.

Which sentence is the main idea sentence?

• Recall that breathing accomplishes two essential functions.

• Proper airway management must always be paired with the assessment of adequate breathing to ensure that both of these critical functions are occurring.

• A thorough primary assessment focuses on a rapid evaluation of both airway and breathing and identifies immediate life threats associated with the airway and the respiratory system.

• By securing the airway, you provide an open pathway for air to move into and out of the body.

Multiple Choice

The main idea in the previous page is

• implicitly stated. The main idea is implied.

• explicitly stated. The main idea obvious.

Which statement below is NOT a supportive detail?

• rapid evaluation of both airway and breathing identifies a life threat

move into and out of the body. However, a patient airway does not

guarantee that the air will move in adequate volumes to support life.

What is the subject or topic of the passage?

• Proper Assessment to Detect Life Threats

• The Body Intakes Oxygen

• The Lungs Expel Carbon Dioxide

• Causes of Airway Obstruction

Multiple Choice

Air is moved into and out of the chest in a process called ventilation. To move air, the diaphragm and the muscles of the chest are contracted and relaxed to change the pressure within the chest cavity. This changing pressure inflates and deflates the lungs. Inhalation is an active process. The muscles of the chest including the intercostal muscles between the ribs expands at the same time the diaphragm contracts in a downward motion. These movements increase the size of the chest cavity. This negative pressure pulls air in through the glottis opening and inflates the lungs. Conversely, exhalation is a passive process. That means it occurs when the previously discussed muscles relax. As the size of the chest decreases it creates a positive pressure and pushes air out. Because it is passive, exhalation typically takes slightly longer than inhalation.

Which one below is NOT a major detail?

• The muscles of the chest including the intercostal muscles between the ribs expands at the same time the diaphragm contracts.

• These movements increase the size of the chest cavity.

• This negative pressure pulls air in through the glottis opening and inflates the lungs.

• Air is moved into and out of the chest in a process called ventilation.

Read the passage again. What is the implied main idea?

• There is a difference between the active process of inhalation versus the passive process of exhalation.

• Inhalation muscles in the chest expand while the diaphragm contracts.

• To move air, the diaphragm and the chest muscles contract and relax.

• This changing pressure inflates and deflates the lungs.

• Inhalation is an active process.
