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).
This requires accessing accurate, relevant knowledge, managing mental processes during reading, and constructing mental representation through “pruning and organizational processes”. These come through good instruction and guidance from the teacher. Also, explicit cognitive strategy instruction and social interaction are important for students to comprehend the text and develop the concepts. Students must rely on accurate background knowledge in order to accurately understand the text.
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?
Since young children rely heavily on background knowledge, it is important to make sure their background knowledge is correct. Teachers must pay attention to the students’ dialogue to make sure they are relying on accurate prior knowledge. In one study, a classroom did interactive read-alouds, however, the students discussed their own experiences. This led to inaccurate representations of the text. Teachers should be concerned about activating prior knowledge because they never know if the knowledge is accurate or inaccurate information.
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 is commonly used with leveled texts. These include small paperbacks that have been leveled using a narrow gradient readability scale. The pictures are used for discussion on what the book is likely to be about. Two to three vocabulary words are introduced in the picture walk. Children use their problem solving skills to figure out the words and their meanings.
Know-Want to Learn-Learn is when the teacher guides discussion and records the students statements about what they know, what they want to learn, and what they learned (after reading).
Directed Reading-Thinking Activity is when the teacher selects a text and divides it into meaningful sections. The teacher facilitates discussion for each section. Students are encouraged to make predictions about the text and justify their predictions. Also, students are encouraged to independently read the text, and revise their predictions after participating in a teacher-led discussion.
4. What is the purpose of the experimental study reported?
The purpose of this study was to observe the picture walk, know-want to learn-learn, and directed reading, and see how they influence the developmental reading abilities of children. Also, it observed the ability for students to learn content when using informational texts.
5. Who were the subjects?
The subjects were 31 struggling second graders. These students were recommended by their teachers and were said to be 3-6 months behind their reading level. They were from a mid-size Midwest city.
6. Describe the reading materials used during the intervention.
The students were given three informational texts a week. These texts were all appropriate for second graders and were based around the same scientific topics.
7. How long did the experiment last?
The experiment lasted for ten weeks, with two four-week periods of intervention. There were twelve days of intervention in each cycle and three consecutive days during the four consecutive weeks. Data was taken on the third day.
8. What were the experimental conditions?
There were four groups that were assigned random orders of the treatment. Since Stahl conducted the experiment over two four week periods, groups 1-4 received treatment in the first period and groups 5-8 received treatment in the second period. At school A, sessions were held at a table in the hallway and at school B, sessions were held at a table in the schools kitchen (or a room shared with other teacher’s working with small groups of children).
9. Describe the procedures specific to the Picture Walk, KWL, DRTA, and the Control Group conditions.
PW- Students were first introduced to the book and given some background knowledge. The students then participated in an interactive picture walk in which they discuss the picture and make predictions. Students were introduced to a couple of vocabulary words during this process.
KWL- On Days 1 and 3, students created KWL charts. Children filled in the “know” column after they were told the topic. On days 2 and 3, students filled in their own personal charts, and then shared their information with the class. Then, the students collaborated on questions they wanted to learn.
DRTA- The book was divided into sections. The students first made predictions about the book by observing the cover page, pictures, text, etc. Then the teacher read a few pages at a time and then had the students make further predictions. The teacher had the students verify/alter their predictions as the book was read.
Control- In this group students were given an overview of the information. Then the students mumble read the book and drew a picture or wrote something about the book after they read it.
10. What measures were used to determine the relative effectiveness of the treatments? Describe the measures briefly.
One of the measures was vocabulary recognition task. The task consisted of 25 words, 18 related to the content and 7 unrelated. Students circled the words they were able to read. Another task was the maze task. The original text read by the kids was reprinted after the deletion of ten words. This was a multiple-choice cloze modification and the score was the number of correct responses. Then, after their free recall, they were given three explicit and three implicit for the cued recall. At the end of the study, the students were interviewed and their responses were recorded.
11. Which treatment(s) were found to be more effective in increasing students’ vocabulary knowledge and maze performance (p. 381)?
Even though all treatments promoted the advancement of vocabulary, picture walk seemed to be the most effective. In addition, both the PW and DRTA yielded statistically significant effects on the maze. Both of these procedures were more effective than KWL or the control procedures in developing reading skills.
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)?
This was probably because in the DRTA, there was a lot of teacher guidance. The teacher was able to promote discussion and guide the comprehension of the students.
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 means that when you ask the student to re-call or re-tell the story, their prior knowledge does not have a lot of influence on their responses.
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?
Teacher support is really important for students. Teachers must be aware of the students’ prior knowledge on the topic and make sure their prior knowledge is correct. Teachers must find ways to combine students prior knowledge and the topics in the book to create accurate mental representations for students.
