Goals for Understanding:
• How to determine text difficulty/readability level
• How text features support (or do not support) readers in constructing a coherent mental representation of a text
• How to analyze a text (and its language) for its resource and challenges
• (Later: How to use text analysis to set learning goals for a discussion about the text)
What makes a text difficult?
• Cornett: Interest level (personal); Accessibility (emotional & cognitive); Readability (text difficulty);
• Reading level (the reader)– Independent (95-99% accuracy; 90% comp)– Instructional (90-95% accuracy; 80% comp)– Frustrational (<90% accuracy; < 70% comp)– Listening (comprehend 80% key concepts)

Key Text Features that Influence Comprehension
• Genre
• Text organization (e.g., chronology, cause/effect, compare/contrast)
• Graphics and typographic features
• Transitions (e.g., between paragraphs)
• Connectives
• Referents
• Cohesion
Adapted from Kucan & Palincsar IES 2009-2010
15
Ways of thinking about text features and text difficulty we have investigated
• Readability measures:– Text difficulty is judged by vocabulary
(how long the words are/how many syllables) and the length of sentences
• Readability measures assume that:– Longer sentences are more difficult to process– Bigger/longer words, or words that appear less
frequently are less familiar to readers
• We discovered some problems with readability measures. Many other features besides vocabulary and sentence length influence how a reader constructs meaning from text
Adapted from Kucan & Palincsar IES 2009-2010
16
What are the other features influence how a reader constructs meaning?
• We already thought of some features, like– Text Structure (narrative, expository, hybrid,
genre)– Text organization (chronology, cause/effect)– Graphics– Typographical features (type face, bold,
italics, etc.)

Let’s Look at these Text Features More Closely
Why/How do these text features support and/or complicate
comprehension?
Adapted from Kucan & Palincsar IES 2009-2010
18
Text Structure: GenreUnderstanding the genre of a text (e.g., folk tale, nonfiction,
historical fiction, mystery or biography) allows readers to have certain expectations about the content and organization of the text. (Helps set purpose; monitor)
Adapted from Kucan & Palincsar IES 2009-2010
19
Hybrid texts include more than one genre
Story on one side, biography on the other
Narrative story of Mrs. Frizzle and her class (problem, events…) intertwined with scientific explanation of phenomenon
20
Text organization: Chronology
• Well-organized accounts of events can help readers understand the order in which events took place.
• The tense of verbs (past, present, and future) can help readers keep track of the sequence of events.
• Words like first, next, then, finally, after help the reader keep track of sequence/time.
• BUT, authors may use other devices such as “flash-forward” or “flash-back.”

Does organization support or complicate comprehension?
Adapted from Kucan & Palincsar IES 2009-2010
21
Text Organization:Cause and Effect
• In well-organized accounts of events related by cause and effect, authors connect the cause and effect by using words and phrases like as a result, because, and therefore.
• The distance between the information provided about the cause-and-effect relationship also contributes to text difficulty.
Adapted from Kucan & Palincsar IES 2009-2010
22
Graphics
• Graphics, such as photos, tables, charts, maps, and illustrations, can support readers to build coherent mental representations
• BUT, graphics can also interfere with that process • How do we know if graphics are helpful?
– Location (where are they placed?)– Relationship between the graphic and the text
(location, and how explicitly they are connected)– Clarity
Adapted from Kucan & Palincsar IES 2009-2010
23
Typographic features
• Typographic features and the layout of text also influence the ease of reading.
• Typographic features include:
– boldface, italics, size of type
– headings and subheadings

25
Transitions
• Well-constructed texts support readers by providing transitions between paragraphs.
• One kind of transition lets the reader know that the topic of the same paragraph is still being considered.
For example, if a paragraph is about photosynthesis, the following paragraph may begin with a sentence like this:
There is more that scientists know about photosynthesis.Such a sentence cues readers that they will be reading
more about this topic.
Adapted from Kucan & Palincsar IES 2009-2010
26
Transitions, Continued
• Authors often choose to repeat the key word to support the transition to a new paragraph about the same topic.
• Transitions can also signal that a new topic is going to be introduced.
For example, a sentence like the following indicates that the author is moving from the topic of year-round schools to the topic of school size:
Although year-round schools have received a lot of attention in predicting student success, others think that school size is the more important factor in predicting school success.
Adapted from Kucan & Palincsar IES 2009-2010
27
Text Organization: Connectives
• Authors signal how ideas are connected by using words known as “connectives” (e.g., because, so, either-or, however, therefore, despite).
• Sometimes authors don’t provide these connectives, and readers have to do the work of building connections.
For example:
Many citizens were outraged. When the polls were scheduled to close, some voters who were still in line to vote had been turned away. The local election board called for an investigation.

29
Referents
• Referents are words that refer to the same person, thing, place, or idea; for example, he, they, it, who,which, here.
• Pronouns are common referents
• Sometimes authors use phrases to refer to the same person. For example, in a text about Roberto Clemente, Roberto is referred to as “the young man,” “the right fielder,” and “the young Puerto Rican.”
Language• Figurative language such as
– Metaphor– Simile– Personification
• Figurative language is most often found in literary or fiction text (narrative)
• Colloquialisms/vernacular dialect (again, found in narrative)– I wasn’t born yesterday; grinder; coke; fixin’ to make
groceries

The role of cohesion in thinking about text features and text difficulty
• Cohesion is the “linguistic glue” that links events and concepts together in a text
• A whole text can be cohesive, but there is also cohesion between sentences, groups of sentences, paragraphs, and chapters
• Cohesive texts support readers in building coherent mental representations of a text
• Less cohesive texts require readers to infer more information to build coherent mental representations
Adapted from Kucan & Palincsar IES 2009-2010
32
Constructing a coherent mental representation
Cohesive Text• Text ideas are well
connected
• Readers understand how text ideas relate to one another
Non-Cohesive Text• Connections among text
ideas are not clear
• Readers must make inferences to connect text ideas
Quickwrite

Applying These Ideas… (Resources? Challenges?)
• Genre
• Text organization (e.g., chronology, cause/effect, compare/contrast)
• Graphics and typographic features
• Transitions (e.g., between paragraphs)
• Connectives
• Referents
• Cohesion
Applying these ideas…
• Helpful? • Not helpful – challenges?

How do you use this information about text difficulty to plan your instruction?
• Main Idea:
• Big Idea:
• Introduce: What would you do BEFORE reading?

Text (and Language) Features That Influence Difficulty
• Lion King• Puff the Magic Dragon• Eleven
• What’s the main idea (your key insights) about the role of language for influencing comprehension?
• Talk in your group to generate two key ideas
38
Language Features
• Decontextualized Language – written language is harder to read when we only have words– No help from pictures, mood, color, gestures, sounds of
voice, music, etc. – When we add contextualization, is it helpful? Could it
ever make comprehension more challenging?
• Metaphoric Language – language that uses the literary device of metaphor to transfer meaning of one word to another word
Adapted from Kucan & Palincsar IES 2009-2010
39
Determining Main Ideas and Big Ideas
• Consider: • Is it easier to determine main ideas from
narrative text or informational text? Why?
• Is it easier to determine big ideas from narrative text or informational text? Why?
40
Reviewing MTH Book Activity 2• Activities go all together to help students learn about the
topic (Big Idea or several main ideas)• Hybrid text: Combine what two genres? • Main idea (plot events); Big Idea (any content?)• Unit Map:
– Where get ideas? (from “facts” in Part 1) – Learning outcomes not always clear… state as questions or
goals to help focus your instruction • “Compare differences between common English then & now”• “Create postcard from a soldier’s perspective in civil war” • “What animals do Indian cultures worship? ”
• It’s vs. Its (no apostrophe unless two words
