1. Describe in broad stokes the reading processes that take place during comprehension of informational text (p. 362, under Construction of Meaning and Concept Development with Informational Texts).
For effective comprehension to take place within readers they must access accurate, relevant knowledge, manage mental processes during reading within the confines of a limited working memory, and construct a coherent mental representation through pruning and organizational processes.
2. Specify the effect that background knowledge may have on constructing mental representations from informational text. Why should teachers be concerned about activating prior knowledge?
Background knowledge helps to engage students in a text because they can relate it to their individual experiences, knowledge, or memories. However, it also can distract readers from what’s happening in the story because they completely rely on their background knowledge to construct meaning of the new text. Teachers must be careful of how much dialogue they create surrounding the text being presented because children can easily dwell on prior knowledge and tend to have inaccurate or limited recollection of the presented text.
3. What are the three instructional approaches that can be used to help primary-grade students comprehend informational text? Describe their common (p. 365) and distinctive features (p. 363-5).
Picture Walk
- Commonly used with leveled text
- Conversations typically occur as the teacher and students preview each page or few pages of a new book, before reading
- Pictures are used as a catalyst for a discussion of what the book is likely to be about
- Two or three vocabulary words are explicitly introduced
- Designed to yield student-generated discussion and predictions about a text
Know-Want to Learn-Learn
- Enable teachers to access the prior knowledge of students and to help students develop their own purposes for reading expository text.
- Uses a chart or worksheet to record students’ statements about what they know (K), want to learn (W), and, after reading, what they learned (L)
Directed Reading-Thinking Activity
- Views reading as a problem-solving process best accomplished in a social context
- Students are responsible for establishing their own purposes for reading
“All three approaches are structured, teacher-facilitated social interactions, focused on increasing students’ comprehension of text. All three approaches engage students in generating purposeful predictions based on prior knowledge and informational text features, such as pictures, tables of contents, and headings.”
Commonalities:
(a) An emphasis on reader engagement and social mediation,
(b) Activation of relevant prior knowledge, and
(c) Anticipation (or purposeful prediction) of what information might be likely to be included in a text.
4. What is the purpose of the experimental study reported?
“The purpose of this study was to explore how the PW, KWL, and DRTA might influence developmental reading abilities and content acquisition when used with informational text in the primary reading group context.”
5. Who were the subjects?
31 second-grade students in two demographically similar schools, in the same school district, in a midsize Midwest city
6. Describe the reading materials used during the intervention.
The books were informational texts on topics that were likely to be familiar to second-grade students.
Sequence of topics: spiders, the moon, how water changes form, and insects
7. How long did the experiment last?
Over 10 weeks, conducting two four-week periods of intervention within that time frame
8. What were the experimental conditions?
Groups 1 through 4 from School A received the intervention during the first cycle, and Groups 5 through 8 from School B received the intervention during the second four-week cycle. Following two days of individual pre-experimental screening to ensure that readers shared a common instructional level, a I 45-minute orientation session was conducted with each group. There were 12 days of intervention in each cycle (three consecutive days for each of four consecutive weeks). Each group received each treatment for three days, with data being collected only on the third day. On the day following the conclusion of the intervention cycle, students were interviewed about the comprehension strategies and instructional preferences.
9. Describe the procedures specific to the Picture Walk, KWL, DRTA, and the Control Group conditions.
Picture Walk
- presented a brief overview of the text
- engaged in an interactive discussion about the book as we worked through the book page-by-page, talking about the pictures, the text structure, and the student’s prior knowledge, and formulating predictions based on that information questions were asked to generate discussion
- specifically introduced new vocabulary before reading the text
- Students were taught the meaning of the selected vocabulary, and they were coached in decoding strategies, perhaps chunking or using a common rime
- Afterwards the children mumble read the text independently and then come back together to make further predictions
KLW
- Introduced topic, students discussed and then their input was written on the chart in the Know column
- Each child wrote what he or she knew on a personal KWL chart before it was shared and written on our large group chart
- Children categorized the recorded information
- Children to generated questions about the topic in the “What I Want to Learn” column
- After reading, there was a post-reading discussion by considering whether the text had provided answers to any student questions. Then they recorded the information in the “What I Learned” column.
- Discussed other new learning and recorded it on the group chart
DRTA
- Before reading, the students formulated and justified predictions about the text based on the title, cover, prior knowledge, and if available, table of contents
- Students predicted for a two-page or three-page section of text
- A brief discussion was held to verify predictions, summarize the information in the text, and generate new predictions for the next section of text based on the discussion about the text, pictures, and headings, if available
Control Group
- Before reading, presented the same brief overview of the text that had been provided to the treatment groups
- Children independently mumble read the new text
- Independent reading was always followed by drawing a picture and/or writing about something they would like to share with the group based on the text
10. What measures were used to determine the relative effectiveness of the treatments? Describe the measures briefly.
Vocabulary Recognition Task (VRT)
- Children were asked to identify words that they could both read and were related to the topic; this technique of “yes/no” was a reliable and valid measure of vocabulary assessment.
Maze
- Maze provided insight into micro-level processing, general reading, and monitoring for meaning
- The maze task was a multiple-choice cloze modification. It was a timed (three minutes), group-administered task. The original text read by the students was reprinted after the deletion of 10 content words. The score on the maze task was the number of correct responses.
Free Recall
- Individually each child provided a free recall of the day’s text.
- Two raters parsed the
- Texts into clausal units, developed tree diagrams to determine ideational hierarchies, and placed these ordered clausal units on coding sheets. Student retellings were then analyzed using coding sheets
Cued Recall
- After the free recall, each child was asked to answer three explicit and three implicit questions based on that day’s text.
- They looked for correctness of an answer and then judged the response on a four point scale which was used to produce weighted scores for each answer
Post-intervention Interview
- At the conclusion of each research cycle, individual strategy interviews were conducted with the students in that cycle.
- The questions surveyed three types of strategy knowledge (a) declarative (what the strategies were), (b) procedural (how to perform the strategies) and (c) conditional knowledge (when and why the strategies are useful)
11. Which treatment(s) were found to be more effective in increasing students’ vocabulary knowledge and maze performance (p. 381)?
- The use of informational texts with novice readers does extend their vocabularies. The small group setting seemed to be essential for these approaching-grade-level students to develop content area vocabulary that had previously been taught as part of the district’s science curriculum. And all three instructional approaches worked equally well.
- Both the PW and DRTA yielded statistically significant effects on the maze.
12. Students’ comprehension of the texts was greater under the DRTA condition than KWL and the control conditions. What do you think explains DRTA’s advantage over the KWL condition (p. 382)?
Teacher guidance during the DRTA tended to direct the children’s attention to the important ideas and assist with difficult text concepts in a way that was not provided for in the other interventions. The scaffolded interactions during reading, actively justifying and verifying predictions, integrating text-based information with prior knowledge, and having an immediate opportunity to discuss new concepts seemed to help these novice readers when they were called on to respond to questions about the text. The KWL and control conditions did not allow for children to be as analytical with text and create critical thinking and reasoning. Instead, they just required children to regurgitate facts or events.
13. It was found that the treatments did not differ in the quality and quantity of students’ retellings (p. 384). In other words, students were not differentially affected by the treatments in the way they integrated textual information with prior knowledge. What does this finding mean in terms of the different emphases employed by experience-based (KWL) vs. text-based (DRTA) treatments?
Ultimately, experienced-based (KWL) charts are not better for children than text based (DRTA) because children reap no benefits of understanding the text better with prior knowledge of content.
Answer the following question AFTER you read the article.
14. In light of the findings from this study, what conclusions can you draw about the role of teacher support in children’s construction of mental representations from informational text?
It is vital that while reading a text the teacher should provide and facilitate text-appropriate questions that require the child to experience critical thinking and reasoning. This process helps children develop a better understanding of how to comprehend and reason with new information that they are given through text and orally.
