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).
Comprehension of informational texts requires accessing accurate, relevant knowledge, managing mental processes (both top-down and bottom-up) during reading within the confines of limited working memory, and constructing 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?
The effect that background knowledge may have on constructing mental representations from informational text is that children rely heavily on background knowledge in their interactions with text. Teachers should push for students to use their background knowledge because they can build upon what they already know, however , they too need to be careful that the students do not rely on inaccurate or irrelevant background knowledge.
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).
The three instructional approaches that can be used to help primary grade students comprehend information text are picture walk (PW), know-want to learn-learn (KWL), and directed reading-thinking activity (DRTA). All three approaches are structured, teacher-facilitated social interactions, and focused on increasing students’ comprehension of text. In addition, 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.
Picture Walk (PW): PW is commonly used with leveled text – small paper backs that have been leveled using a narrow gradient readability scale based on qualitative text features. In picture walk, the teacher and students preview each page or few pages of a new book before reading it. The pictures are used as a catalyst for a discussion of what the book is likely to be about. Lastly, two or three vocabulary words are introduced during the PW as well.
Know-Want to Learn-Learn (KWL): KWL was originally developed by Ogle to enable teachers to access the prior knowledge of students and to help students develop their own purposes for reading expository text. The teacher generates a discussion about a text topic and uses a chart or worksheet to record students’ statements about what they know (K), wan to learn (W), and, after reading, what they learned (L). Lastly, Ogle found that KWL is appropriate with information text, and can be used in any grade or content area.
Directed Reading-Thinking Activity (DRTA): In DRTA the teacher selects an instructional level text (book) and then divides the text into meaningful sections. Then the teacher facilitates the discussion of each section of the book, and the students are responsible for establishing their own purposes for reading, generating predictions, justifying those predictions, independently reading the text, and verifying or revising predictions based on evaluations of information in the text during the teacher-led discussion of each section.
4. What is the purpose of the experimental study reported?
The purpose of the experimental study was to explore how the PW, KWL, and DRTA might influence developmental reading abilities and content acquisition when used with information text in the primary reading group context.
5. Who were the subjects?
The subjects were 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 materials used during the intervention were informational texts on topics that were likely to be familiar to second-grade students. The text addressed science topics that had been taught to the students in their first or second grade science curriculum as part of the state science content standards. The topics for each group during both cycles were: spiders, the moon, how water changes form, and insects. Each week three different informational texts were used that focused on the various science topics.
7. How long did the experiment last?
The data that was gathered was collected over a ten week period. There were two four-week periods of intervention within that time frame. Groups one through four from School A received the intervention during the first cycle, and Groups five through eight from School B received the intervention during the second four-week cycle. Overall, there were twelve days of intervention in each cycle (three consecutive days for each four consecutive weeks).
8. What were the experimental conditions?
The experimental conditions were (PW, LWL, DRTA, and Control). A random order of treatment was applied, so every student would receive each of the four treatments. This helped increase the validity of the experiment.
9. Describe the procedures specific to the Picture Walk, KWL, DRTA, and the Control Group conditions.
Picture Walk (PW): In PW, the teacher would do a brief overview of the text. Then together, students and teacher would engage in an interactive discussion about the book by going through the books pages, talking about the pictures, the text structure, and the student’s prior knowledge, and formulating predictions based on that information. In addition, topic headings were addressed, when available. This method is the only way that specifically introduces new vocabulary before reading the book. Lastly, following the reading, the teacher would have the students read independently and then discuss what they read and if their predictions were right.
Know-Want to Learn-Learn (KWL): In KWL a topic would be introduced and the children would discuss the topic. Students input would be written on a KWL chart in the “Know” column. All of this would be done on Day 1 and Day 3. Then on Day 2 and Day 3, the students would write what he or she knew on their personal KWL chart before sharing and writing what they knew on the class KWL chart. Next, students would categorize the information. Then the students would generate questions about the topic and place them in the “What I Want to Learn” column. However, before placing them in the column, the teacher would provide a brief overview of the book. Then the table of contents of the book would be discussed, if available. This would help the students to be able to anticipate the content and generate questions that could actually be answered in each book. Each day the teacher would write the students questions in the “want to learn” column, on the class KWL chart. To help the students generate questions the teacher would guide discussions. The following the pre-reading discussion, students would mumble read the entire text, and then after reading, teachers and students would start a post-reading discussion by considering whether the text had provided answers to any of the students questions. If so, then the teacher would record the information in the “What I Learned” column. Then together the teacher and students would discuss other new learning and record them as well.
Directed Reading-Thinking Activity (DRTA): In DRTA, students would formulate and justify their predictions about the text based on the title, cover, prior knowledge, and if available, the table of contents. Students would predict for a two-page or three-page section of text, and then they would mumble read that section of text. After reading each section of the text, the teacher would do a brief discussion to verify predictions, summarize the information in the text, and generate new predictions for the next section of the text based on the discussion about the text, pictures, and headings. Then in the end the teacher would discuss the minimal amount about the text.
Control Group: In the control group the students would receive a general overview of the text, just like in the other three, and then the children would independently mumble read the new text. Following that the students would draw a picture or write 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.
The measures used to determine the relative effectiveness of the treatments were: The Vocabulary Recognition Task (VRT), Maze Task, Free Recall, Cued Recall, and Post-intervention Interview.
The Vocabulary Recognition Task (VRT): The VRT is an experimenter constructed yes/no task used to estimate vocabulary recognition in a content area and to confirm that groups had similar levels of prior knowledge of the topic. The task consisted of a list of 25 words; 18 of the words were related to the content in the informational texts and 7 words were unrelated foils. Students circled the words that they both were able to read and related to the topic. Then VRT would categorize those words under provided headings on a concept web.
Maze Task: This 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. All maze texts ranged from 254 to 267 words.
Free Recall: In Free Recall, each child provided a free recall of the day’s text. Students told everything they could remember about the text they read that day and what the book made them think of. Then two raters parsed the texts into casual units. Tree diagrams were to determine ideational hierarchies, and placed these ordered clausal units on coding sheets.
Cued Recall: In cued recall, each child was asked to answer three explicit and three implicit questions based on that day’s text. First, items were scored as correct or incorrect as a measure of general comprehension. Both correct and partially correct items were scored as correct. Next, a four point scale was used to produce weighted scores for each answer.
Post-intervention Interview: At the end of each research cycle, and individual strategy interviews were done with the students in that cycle. Interviews were recorded on audiotape and transcribed. The interview was adapted by Duffy to determine if students gained knowledge of the two common strategies, activation of prior knowledge and prediction. The questions surveyed three types of strategy knowledge: declarative (what the strategies were), procedural (how to perform the strategies), and conditional knowledge (when and why strategies are useful). The students were able to refer to a new informational text that was provided as a means of making discussion less abstract. The final two questions related to the instructional methods. Following the poster-aided review of the four instructional methods, students were asked to reflect on their preferred approach for enjoyment and helpfulness. Then finally, descriptive analysis of information gathered in the interviews was performed.
11. Which treatment(s) were found to be more effective in increasing students’ vocabulary knowledge and maze performance (p. 381)?
The treatments that were found to be more effective in increasing students vocabulary knowledge and maze performance was all three treatments. They all three had vocabulary gains, yet, the PW and DRTA were more effective for the maze task than the KWL and control group.
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)?
The reason why students’ comprehension of the texts was greater under the DRTA condition is because DRTA is more structural. It directs the students’ attention to the more important areas of the text and helps the students understand the more difficult concepts. In addition, DRTA has a higher level of thinking than the other three conditions. All and all, these reasons are why students’ comprehension was greater under the DRTA condition than the KWL and the control conditions.
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?
It means that both KWL and DRTA are effective teaching methods when it comes down to students retelling. Both experienced-based (KWL) and text-based (DRTA) can achieve the same results when it comes down to students retelling.
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?
The conclusion I drew is it is important that teachers use one of the three approaches when reading informational texts. As a teacher you should always support your students, whether you use any of the three approaches. All and all, students construct mental representations in various ways, therefore, it is up to the teacher to use any of the methods to help the students with their reading.
