Vocabulary: Instructional Guidelines and Classroom Examples
This article provides examples of classroom instructional techniques as well as specific activities for helping students build their vocabularies.
Vocabulary instruction techniques
Teaching specific words
- engage students in a discussion of the concept of taxes; and/or
- read a sentence from the book that contains the word taxes and ask students to use context and their prior knowledge to try to figure out what it means.
To solidify their understanding of the word, the teacher might ask students to use the word taxes in their own sentences.
Word learning strategies
- how to use dictionaries and other reference aids to learn word meanings and to deepen knowledge of word meanings;
- how to use information about word parts to figure out the meanings of words in text; and
- how to use context clues to determine word meanings.
Using dictionaries and other reference aids
Students must learn how to use dictionaries, glossaries, and thesauruses to help broaden and deepen their knowledge of words, even though these resources can be difficult to use. The most helpful dictionaries include sentences providing clear examples of word meanings in context.
As his class reads a text, a second-grade teacher discovers that many of his students do not know the meaning of the word board, as in the sentence, "The children were waiting to board the buses." The teacher demonstrates how to find board in the classroom dictionary, showing students that there are four different definitions for the word. He reads the definitions one at a time, and the class discusses whether each definition would fit the context of the sentence. The students easily eliminate the inappropriate definitions of board, and settle on the definition, "to get on a train, an airplane, a bus, or a ship."
The teacher next has students substitute the most likely definition for board in the original sentence to verify that it is "The children were waiting to get on the buses" that makes the best sense.
Using word parts
Word parts include affixes (prefixes and suffixes), base words, and word roots.
are word parts that are "fixed to" either the beginnings of words (prefixes) or the ending of words (suffixes). The word disrespectful has two affixes, a prefix (dis-) and a suffix (-ful).
are words from which many other words are formed. For example, many words can be formed from the base word migrate: migration, migrant, immigration, immigrant, migrating, migratory.
are the words from other languages that are the origin of many English words. About 60% of all English words have Latin or Greek origins.
Knowing some common prefixes and suffixes (affixes), base words, and root words can help students learn the meanings of many new words. For example, if students learn just the four most common prefixes in English (un-, re-, in-, dis-), they will have important clues about the meaning of about two thirds of all English words that have prefixes. Prefixes are relatively easy to learn because they have clear meanings (for example, un- means "not" and re- means "again"); they are usually spelled the same way from word to word; and, of course, they always occur at the beginnings of words.
Learning suffixes can be more challenging than learning prefixes. This is because some suffixes have more abstract meanings than do prefixes. For example, learning that the suffix -ness means "the state or quality of" might not help students figure out the meaning of kindness. Other suffixes, however, are more helpful, for example, -less, which means "without" (hopeless, thoughtless); and -ful, which means "full of" (hopeful, thoughtful).
Latin and Greek word roots are found commonly in content-area school subjects, especially in the subjects of science and social studies. As a result, Latin and Greek word parts form a large proportion of the new vocabulary that students encounter in their content-area textbooks. Teachers should teach the word roots as they occur in the texts students read. Furthermore, teachers should teach primarily those root words that students are likely to see often.
- A second-grade teacher wants to teach her students how to use the base word play as a way to help them think about the meanings of new words they will encounter in reading. To begin, she has students brainstorm all the words or phrases they can think of that are related to play. The teacher records their suggestions: player, playful, playpen, ballplayer, and playing field. Then she has the class discuss the meaning of each of their proposed words and how it relates to play.
- A third-grade teacher identifies the base word note. He then sets up a "word wall," and writes the word note at the top of the wall. As his students read, the teacher has them look for words that are related to note and add them to the wall. Throughout their reading, they gradually add to the wall the words notebook, notation, noteworthy, and notable.
Using context clues
Context clues are hints about the meaning of an unknown word that are provided in the words, phrases, and sentences that surround the word. Context clues include definitions, restatements, examples, or descriptions. Because students learn most word meanings indirectly, or from context, it is important that they learn to use context clues effectively.
Not all contexts are helpful, however. Some contexts give little information about a word's meaning. An example of an unhelpful context is the sentence, "We heard the back door open, and then recognized the buoyant footsteps of Uncle Larry." A number of possible meanings of buoyant could fit this context, including heavy, lively, noisy, familiar, dragging, plodding, and so on. Instruction in using context clues as a word-learning strategy should include the idea that some contexts are more helpful than others.
Extended and active engagement with vocabulary
A first-grade teacher wants to help her students understand the concept of jobs, which is part of her social studies curriculum. Over a period of time, the teacher engages students in exercises in which they work repeatedly with the meaning of the concept of jobs. The students have many opportunities to see and actively use the word in various contexts that reinforce its meaning.
The teacher begins by asking the students what they already know about jobs and by having them give examples of jobs their parents have. The class might have a discussion about the jobs of different people who work at the school.
The teacher then reads the class a simple book about jobs. The book introduces the idea that different jobs help people meet their needs, and that jobs either provide goods or services. The book does not use the words goods and services, rather it uses the verbs makes and helps.
The teacher then asks the students to make up sentences describing their parents' jobs by using the verbs makes and helps (e.g., "My mother is a doctor. She helps sick people get well.")
Next, the teacher asks students to brainstorm other jobs. Together, they decide whether the jobs are "making jobs" or "helping jobs." The job names are placed under the appropriate headings on a bulletin board. They might also suggest jobs that do not fit neatly into either category.
The teacher might then ask the students to share whether they think they would like to have a making or a helping job when they grow up.
The teacher next asks the students to talk with their parents about jobs. She tells them to try to bring to class two new examples of jobs one making job and one helping job.
As the students come across different jobs throughout the year (for example, through reading books, on field trips, through classroom guests), they can add the jobs to the appropriate categories on the bulletin board.
Repeated exposure to words
A second-grade class is reading a biography of Benjamin Franklin. The biography discusses Franklin's important role as a scientist. The teacher wants to make sure that her students understand the meaning of the words science and scientist, both because the words are important to understanding the biography and because they are obviously very useful words to know in school and in everyday life.
At every opportunity, therefore, the teacher draws her students' attention to the words. She points out the words scientist and science in textbooks and reading selections, particularly in her science curriculum. She has students use the words in their own writing, especially during science instruction.
She also asks them to listen for and find in print the words as they are used outside of the classroom-in newspapers, magazines, at museums, in television shows or movies, or the Internet.
Then, as they read the biography, she discusses with students in what ways Benjamin Franklin was a scientist and what science meant in his time.
