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).
Cognitively, comprehension of informal texts requires accessing accurate, relevant knowledge, managing mental processes during reading, 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?
Young children develop concepts and mental representations through experiences, social interactions, and language development. Written text plays an increasingly important role in the formation of concepts and mental representations. Concerning text, students can use the text they are reading to see if their background knowledge is accurate and teachers can correct any incorrect prior 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).
Three instructional approaches that can be used to help primary grade students comprehend information text are picture walks, know-what to learn-learn, and directed reading thinking activities. Common features of these three activities include emphasis on reader engagement and social mediation, activation of relevant, prior knowledge, and anticipation of what information might be likely to be included in a text. There are also distinctive features for each approach. These features are listed below.
Picture Walk: This approach requires students and the instructor to preview the text by exploring the pictures in the book. Also with this approach predictions are made on a page-by-page basis.
Know-What to Learn-Learned: This approach is more open-ended than the other two. It allows students to share their previous knowledge, and open a door for further discussion about what more they would like to learn. Teachers can observe comprehension as students can state what they learned.
Directed Reading Thinking Activity: This approach views reading as a problem solving process. During this approach the text is divided into meaning sections where students make predictions based on what they have just read and have thoughtful discussions.
4. What is the purpose of the experimental study reported?
To explore how the above approaches 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 struggling second grade students from two demographically similar schools. The subjects were divided into 8 groups with each group containing 4 students.
6. Describe the reading materials used during the intervention.
The reading materials were texts that are familiar to second graders (spiders, the moon, insects, etc). Each week three different information texts were used that contained common information about the same topic. A total of 12 texts were used throughout the study.
7. How long did the experiment last?
The experiment lasted for two four-week cycles.
8. What were the experimental conditions?
- Pre-experimental screening was conducted to ensure a common instructional level among students.
- A 45 minute overview session with each group.
- 12 days of intervention for each cycle.
- Groups received treatment for three days with data being collected on the 3rd day.
- Following the intervention, students were interviewed about the comprehension of the strategies
9. Describe the procedures specific to the Picture Walk, KWL, DRTA, and the Control Group conditions.
PW: Teachers and students look at the pictures within the book and predict what they think will occur in the story. Two or three vocabulary words are introduced during this procedure.
KWL: The class makes a chart interactively. They discuss prior knowledge before reading, pose questions that they would like to learn more about, and fill out what they learned after reading the text.
DRTA: The teachers decides on stopping points throughout the story. At the points students discuss what has occurred up to that point and make predictions about what will happen next.
Control Group: The same texts were read, however the control group only had to draw a picture or write something short about what they read.
10. What measures were used to determine the relative effectiveness of the treatments? Describe the measures briefly.
11. Which treatment(s) were found to be more effective in increasing students’ vocabulary knowledge and maze performance (p. 381)?
It was found that the DRTA and the picture walk proved most effective in increasing students’ vocabulary knowledge and maze performance.
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 DRTA approach requires a higher level of thinking by students. The students and teacher interact more in a DRTA than in a KWL chart, and the DRTA provides more guidance. During a DRTA, the scaffolding provides students to actively justify predictions and integrate text-based knowledge with prior knowledge.
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?
This proves that teachers should implement both methods based on the learning style of their students. Since both treatments appear effective, they should judge which one would be more useful on an individual basis.
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?
We as teachers have a huge role in supporting children’s construction of mental representations from informational text. We must activate their previous knowledge and we must correct any incorrect previous knowledge. Similarly, it is our responsibility to choose appropriate approaches to help ensure that our students are learning the most they possibly can.
