Understanding the Main Idea

• Once we've determined the text type of a passage, and what it's generally about, we usually then read on to understand the main idea of the passage. In other words: What is the writer basically telling us? Or, What is the writer's main message? Understanding the main idea of a text means being able to identify the most important point or information in the passage.

Identifying Details• Identifying details in a text to answer specific

questions (eg: who, what, when, where, why) is often achieved through a strategy known as ‘Scanning’ for details. This is actually a technique often used in daily life when looking up a word in the telephone book or dictionary. Also when you read a newspaper, you're probably not reading it word-by-word, instead you're scanning the text for important information of interest.

Understanding Reference

• Understanding reference in a text is an important reading skill which involves focusing on specific meaning of ‘pronoun references’ used throughout a passage (eg: this, those, their, it). This is an important skill to help develop full comprehension of significant details of a section of a passage which refer back to previous statements made.

Paraphrasing

• Paraphrasing involves the skill of identifying a restatement of a section in a passage that retains the basic meaning while changing the words, often explained in a more simplified form. A paraphrase often clarifies a more ambiguous original statement in the text by putting it into alternative words that are often more easily understood.
