Text Features in Informational Texts
Purpose of Text Features
Text features are elements that authors incorporate into informational texts to help readers navigate content, locate information, and comprehend material more effectively. Understanding how text features function enhances reading comprehension and analytical ability.
Organizational Text Features
Headings and Subheadings
Headings indicate main topics while subheadings denote subtopics within those main categories. This hierarchical structure reveals the text's organization and helps readers identify the relationship between ideas.
When analyzing a text's structure, examine how headings are arranged. Sequential headings suggest a process or chronological organization. Parallel headings suggest comparison or equal categories. Increasingly specific subheadings suggest a movement from general to particular.
Table of Contents
The table of contents provides an overview of the text's complete structure, revealing major divisions, the sequence of topics, and the relative emphasis given to different subjects based on page allocation.
Index
The index provides an alphabetical listing of topics with corresponding page numbers, enabling readers to locate specific information quickly. The index reveals what concepts the author considers significant enough to highlight.
Glossary
A glossary defines technical or specialized vocabulary used within the text. The presence and content of a glossary indicate the specialized nature of the subject matter and the target audience's expected knowledge level.
Typographical Text Features
Bold and Italic Text
Bold text typically indicates key terms, important concepts, or vocabulary words. Italic text often signifies emphasis, titles of works, foreign words, or specialized terminology.
Font Size and Style Variations
Variations in font size establish visual hierarchy, with larger fonts indicating greater importance. Different font styles may distinguish between types of content, such as regular text versus quoted material.
Bullet Points and Numbered Lists
Bulleted lists indicate items of equal importance without sequential relationship. Numbered lists suggest sequence, priority, or steps in a process. Both formats signal to readers that information is being presented in a condensed, organized manner.
Graphic Text Features
Photographs and Illustrations
Visual images serve multiple purposes: providing concrete examples of abstract concepts, adding emotional impact, breaking up dense text, and offering information that words cannot easily convey.
When analyzing photographs and illustrations, consider their relationship to the surrounding text, what information they add that is not stated in words, and what perspective or interpretation they suggest.
Diagrams and Charts
Diagrams illustrate processes, structures, or relationships visually. Types include flow charts (showing processes or sequences), organizational charts (showing hierarchies or structures), Venn diagrams (showing relationships and overlaps), and labeled diagrams (identifying parts of a whole).
Graphs
Graphs present numerical data visually, making patterns and relationships easier to perceive. Common types include line graphs (showing change over time), bar graphs (comparing quantities across categories), pie charts (showing parts of a whole), and scatter plots (showing correlation between variables).
Tables
Tables organize information into rows and columns, facilitating comparison and enabling readers to locate specific data points quickly. Tables are particularly useful for presenting complex information that would be unwieldy in prose form.
Maps
Maps provide spatial information, showing locations, distributions, movements, or geographical relationships. They may be physical (showing terrain and natural features), political (showing boundaries and jurisdictions), or thematic (showing distributions of phenomena).
Navigational Text Features
Sidebars
Sidebars contain supplementary information set apart from the main text. They may provide background information, interesting tangents, extended examples, or related content that supports but does not fit within the main narrative.
Captions
Captions explain or provide context for visual elements. Effective captions go beyond merely labeling what is shown, adding information that enhances understanding of the image's significance.
Cross-References
Cross-references direct readers to related information elsewhere in the text, signaling connections between topics and enabling readers to access additional detail on subjects of interest.
Footnotes and Endnotes
Footnotes appear at the bottom of the page; endnotes appear at the end of a chapter or document. Both provide supplementary information, citations, or explanations that would interrupt the flow of main text.
Analyzing Text Features for Comprehension
Previewing Strategy
Effective readers preview text features before reading the main text. Examining headings, subheadings, graphics, and other features provides an overview of content and establishes a framework for understanding.
Integration Strategy
While reading, integrate information from text features with the main text. Graphics and main text should be read together, with readers pausing to examine visual elements when they are referenced.
Text Feature Purpose Analysis
Consider why the author included each text feature. Ask what information the feature provides, how it relates to the main text, what would be lost without it, and whether it effectively serves its apparent purpose.
Text Structure Patterns
Chronological Structure
Information is presented in time order, with events or developments arranged sequentially. Signal words include first, next, then, finally, before, after, and during. This structure is common in historical texts and process explanations.
Cause and Effect Structure
Information is organized around causal relationships, showing how events or conditions lead to outcomes. Signal words include because, therefore, consequently, as a result, and due to.
Compare and Contrast Structure
Information is organized around similarities and differences between subjects. Signal words include similarly, likewise, however, in contrast, on the other hand, and unlike.
Problem and Solution Structure
Information presents a problem followed by one or more solutions. This structure is common in scientific, technical, and policy texts.
Description Structure
Information describes characteristics, features, or attributes of a subject, often organized spatially or by category.
