Students learn about three ways to define a term in technical writing, search the Web for scientific text, then copy and paste sections into a Word document. Finally, they use the highlighter feature of Word to highlight examples of definitions within the text.
Definitions, technical writing, interdisciplinary
Improve students' reading comprehension skills with this cross-disciplinary lesson.
Begin the lesson -- which can be taught either in the English or science classroom -- by discussing what the word "definition" means and where definitions can be found. Share that, in addition to a dictionary or glossary, definitions often can be located within the body of the text itself. Explain to students that when they're learning a new concept in science or other fields, they need to know how to identify definitions as they read an article or textbook.
Tell the class that today's assignment is to identify four ways that definitions can appear in scientific articles.
On a classroom projector or TV monitor, display The Sun-Earth Connection Web site. Read the first paragraph out loud (or have students read it silently), then explain to students that one definition is in the first paragraph of the text and ask them to find it. Students should say that corona is defined as "the sun's hot, churning atmosphere." Ask them how they know that's a definition. They should respond that the phrase "called the" helped students recognize that a definition went before and a term went after that phrase.
Next, with the class watching, copy the whole first paragraph, open a Word document, and paste the paragraph into that document. Drag your mouse over the phrase "the sun's hot, churning atmosphere, called the corona," and then select the Highligher tool from your Formatting toolbar. (The Highlighter tool has an "abc" on it and is near the font color tool. Click View>Toolbars>Formatting if you don't see the toolbar.) Click any color to highlight the phrase as an example of a definition.
Ask students to repeat the above steps as they locate five examples of definitions within the text on each of the Web sites below:
Have students complete the following steps with each article above:
When students are finished, ask for volunteers to share a few examples with the class. As they're sharing, have students identify what in the sentence structure itself indicated a definition. For example, in the second paragraph of the Sun-Earth Connection article, parentheses after the acronym SOHO contained the definition of what SOHO meant.
Ask students to go back to their Word documents, scroll to the bottom, and type:
We can locate definitions in text by the following clues: " Parentheses after a concept
Then have students add additional bullets for other clues they have found. Some examples might be:
AssessmentStudents will be evaluated on their ability to identify types of definitions based upon highlighted texts and bulleted list.
