Comprehension: Theories

INTRODUCTION
The main purpose for reading is to comprehend the ideas in the material. Without comprehension, reading would be empty and meaningless. In our practicum, we have all witnessed cases where students are capable of reading the words, but face much difficulty in expressing their comprehension of the main ideas. An example of this occurrence was a second grade boy named Reggie who loved to read but had difficulty in comprehending what he read. Reggie would eagerly read to an audience since he had a solid grasp of phonemic awareness (sounding out words) and social discourse (reading with expression). When tested by the Reading Specialist, Reggie was placed in a relatively low level reading group. This was due to his inability to demonstrate comprehension of the reading material. This was shocking to the teacher, as he appeared to be a strong reader.
As educators, we need to have an understanding of the theories behind reading comprehension, as well as a working knowledge of some important strategies that can be used in the classroom to increase reading comprehension. In this paper, we are going to focus on three important theories on reading comprehension: the Schema Theory; Mental Models, and the Propositional Theory, and four categories of strategies to improve reading comprehension based on these theories: Preparational, Organizational, Elaboration, and Monitoring.
REVIEW OF LITERATURE
THEORY
Gunning (1996) identifies three main theories of reading comprehension. These theories are Schema Theory, Mental Models, and Proposition Theory.
Schema Theory
Gunning (1996) defines a schema as the organized knowledge that one already has about people, places, things, and events. Kitao (1990) says the schema theory involves an interaction between the reader’s own knowledge and the text, which results in comprehension. This schema, as Gunning defined, can be very broad, such a schema for natural disasters, or more narrow, such as a schema for a hurricane. Each schema is "filed" in an individual compartment and stored there. In attempting to comprehend reading materials, students can relate this new information to the existing information they have compartmentalized in their minds, adding it to these "files" for future use. Based on the Schema Theory, depending on how extensive their "files" become, their degree of reading comprehension may vary.
Mental Model Theory
Another major theory we would like to discuss is the Mental Model. This model can be thought of as a mind movie created in one's head, based on the reading content. Gunning gives a detailed description of this process, stating that a mental model is constructed most often when a student is reading fiction. The reader focuses in on the main character and creates a mental model of the circumstances in which the character finds him or herself. The mental model is re-constructed or updated to reflect the new circumstances as the situation changes, but the items important to the main character are kept in the foreground according to Gunning, (1996).
Perkins (1991) identifies that sometimes misconceptions about important concepts reflect misleading mental models of the topic itself or the subject matter within which it sits. There are, however, interventions the teacher can do to help the reader to stay on track and create a more accurate picture. One suggestion is for the teachers to ask the students to disclose their mental models of the topics in question, through analogy, discussion, picturing, and other ways. This information gives the teacher insight on the student's knowledge gaps and misconceptions, therefore allowing them to help students reconstruct a more accurate picture.
Proposition Theory
The final explanation of comprehension we would like to discuss is the Propositional Theory. This involves the reader constructing a main idea or macrostructure as they process the text. These main ideas are organized in a hierarchical fashion with the most important things given the highest priority to be memorized (Gunning, 1996).
