Key Ideas and Details
Main Idea
The main idea is the central point or overarching message of a text. It is the umbrella under which all other information in the passage falls.
Identifying the Main Idea:
- Locate the topic sentence: Often, the main idea is explicitly stated in the topic sentence, usually at the beginning of a paragraph.
- Consider the overall message: If the main idea isn’t explicitly stated, infer it by considering the overall message the author is trying to convey.
- Eliminate supporting details: Focus on the broader point, not specific examples or evidence.
Types of Main Ideas:
- Stated: Directly stated in the text.
- Implied: Suggested but not directly stated; must be inferred.
Example:
- Text: “Dogs are excellent companions. They provide unconditional love, loyalty, and companionship. They can also help with tasks like guarding homes and assisting people with disabilities.”
- Main Idea: Dogs make wonderful companions.
Supporting Details
Supporting details are the pieces of information that explain, develop, or support the main idea. They provide evidence, examples, or descriptions to clarify the central point.
Types of Supporting Details:
- Facts: Verifiable information.
- Statistics: Numerical data.
- Examples: Specific instances that illustrate the main idea.
- Reasons: Explanations for why something is true.
- Definitions: Clarifications of terms.
Identifying Supporting Details:
- Look for evidence: Supporting details often answer questions like “how,” “why,” or “what.”
- Recognize relationships: They often relate directly to the main idea.
Example:
- Main Idea: Dogs make wonderful companions.
- Supporting Details:
- They provide unconditional love and loyalty.
- They can help with tasks like guarding homes.
- They assist people with disabilities.
Summarizing
Summarizing is condensing a text into a shorter version while preserving the main idea and key supporting details. It involves identifying the most important information and expressing it concisely.
Steps to Summarizing:
- Read the text carefully: Understand the main idea and supporting details.
- Identify key points: Determine the most crucial information.
- Condense information: Express the key points in your own words.
- Maintain clarity and coherence: Ensure the summary is easy to understand and logically organized.
Example:
- Original Text: “Dogs are excellent companions. They provide unconditional love, loyalty, and companionship. They can also help with tasks like guarding homes and assisting people with disabilities.”
- Summary: Dogs are loyal, loving pets that can also provide security and assistance.
Inferencing
Inferencing is reading between the lines to understand information that is implied but not explicitly stated. It involves using clues from the text, your background knowledge, and logical reasoning to draw conclusions.
Steps to Inferencing:
- Identify clues: Look for hints or suggestions in the text.
- Activate background knowledge: Use your prior knowledge to make connections.
- Make logical deductions: Combine clues and knowledge to draw a conclusion.
Example:
- Text: “The woman shivered as she stepped outside. The wind whipped through the trees, and snowflakes began to fall.”
- Inference: It is cold outside.
Fact vs. Opinion
A fact is a statement that can be proven true or false. It is objective and verifiable. An opinion is a personal belief or judgment that cannot be proven true or false. It is subjective and often based on emotions or values.
Identifying Facts and Opinions:
- Look for evidence: Facts can be supported with evidence.
- Consider objectivity: Facts are unbiased, while opinions often reflect personal views.
- Recognize language: Words like “believe,” “think,” “feel,” or “should” often indicate opinions.
Example:
- Fact: The Earth revolves around the sun.
- Opinion: Chocolate ice cream is the best flavor.
Additional Tips:
- Practice regularly: The more you practice these skills, the better you will become.
- Read diverse texts: Expose yourself to different writing styles and genres.
- Annotate as you read: Highlight main ideas, supporting details, and key points.
- Question the text: Ask yourself why the author made certain choices.
By mastering these key concepts, you will be well-prepared to tackle the ATI TEAS 7 reading section.
