The first two areas are three-pronged, involving (a) presentation and structure of text, (b) students' awareness of text presentation and structure, and (c) students' strategic use of text presentation and structure. Text presentation facilitates reading comprehension if (a) main ideas are clearly stated and located at the beginnings of paragraphs; and (b) the relations between important information are clearly indicated by headings, subheadings, signal words, and sentences or paragraphs signaling text organization placed at the beginning of the passage. Extra spacing between thought units in sentences facilitates attention to ideas within sentences. Text structure facilitates reading comprehension, with narrative text structure being generally easier for students to recall and monitor than expository text structures.
However, it may be that simply presenting text in a clear, well-organized manner is not sufficient. Research suggests that students' awareness of that presentation and strategic use of text are also needed to enable students to identify relevant and nonrelevant information, main ideas, and relations between ideas. Normally achieving students appear to strategically use text organization to identify main ideas and relations between ideas. However, if main ideas are not clearly stated, even normally achieving students have demonstrated difficulty identifying important information, summarizing, and integrating information.
Unlike normally achieving students, diverse learners appear less aware of text organization and its use as a strategy. Many comprehension difficulties of diverse learners have been attributed to their deficits in text structure awareness. For example, they have demonstrated difficulty identifying main ideas, and discriminating between relevant and nonrelevant information. While demonstrating a knowledge of strategies, they fail to demonstrate a use of strategies.
The first two convergent areas and the importance of students' awareness and strategic use of text presentation lead to the third convergent area -- explicit instruction in text organization facilitates comprehension. Research supports instruction in the physical presentation of text, text structures, and strategic use of text organization to benefit reading comprehension. Research evidence also supports explicit instruction that follows a general pattern of (a) explaining the skill or component of text structure; (b) telling the importance; (c) modeling how, when, and where to use the skill, and how to evaluate the effectiveness of the skill; (d) providing guided and independent practice; (e) teaching for transfer; and (f) evaluating.
The effect on reading comprehension of the presentation and structure of text is more global than local. Well-presented and structured text results in better comprehension of main ideas and relations between ideas than poorly presented or structured text. Likewise, students who are aware of or have had instruction in the physical presentation of text or text structure demonstrate more global comprehension than students who lack awareness or have not had instruction. Although students who are aware of text structure recall more than students who are not aware of text structure, there is often no difference between these students for local (i.e., details) comprehension.
