   Five Research-Based Ways to Teach Vocabulary
   

Vocabulary is the knowledge of words and word meanings. As Steven Stahl (2005) puts it, "Vocabulary knowledge is knowledge; the knowledge of a word not only implies a definition, but also implies how that word fits into the world." Vocabulary knowledge is not something that can ever be fully mastered; it is something that expands and deepens over the course of a lifetime. Instruction in vocabulary involves far more than looking up words in a dictionary and using the words in a sentence. Vocabulary is acquired incidentally through indirect exposure to words and intentionally through explicit instruction in specific words and word-learning strategies. According to Michael Graves (2000), there are four components of an effective vocabulary program:

1. 
   wide or extensive independent reading to expand word knowledge
   
2. 
   instruction in specific words to enhance comprehension of texts containing those words
   
3. 
   instruction in independent word-learning strategies, and
   
4. 
   word consciousness and word-play activities to motivate and enhance learning
   

The National Reading Panel (2000) concluded that there is no single research-based method for teaching vocabulary. From its analysis, the panel recommended using a variety of direct and indirect methods of vocabulary instruction.
Intentional vocabulary teaching
Specific Word Instruction
Selecting Words to Teach
Rich and Robust Instruction
Word-Learning Strategies
Dictionary Use
Morphemic Analysis
Cognate Awareness (ELL)
Contextual Analysis
According to the National Reading Panel (2000), explicit instruction of vocabulary is highly effective. To develop vocabulary intentionally, students should be explicitly taught both specific words and word-learning strategies. To deepen students' knowledge of word meanings, specific word instruction should be robust (Beck et al., 2002). Seeing vocabulary in rich contexts provided by authentic texts, rather than in isolated vocabulary drills, produces robust vocabulary learning (National Reading Panel, 2000). Such instruction often does not begin with a definition, for the ability to give a definition is often the result of knowing what the word means. Rich and robust vocabulary instruction goes beyond definitional knowledge; it gets students actively engaged in using and thinking about word meanings and in creating relationships among words.
Research shows that there are more words to be learned than can be directly taught in even the most ambitious program of vocabulary instruction. Explicit instruction in word-learning strategies gives students tools for independently determining the meanings of unfamiliar words that have not been explicitly introduced in class. Since students encounter so many unfamiliar words in their reading, any help provided by such strategies can be useful.
Word-learning strategies include dictionary use, morphemic analysis, and contextual analysis. For ELLs whose language shares cognates with English, cognate awareness is also an important strategy. Dictionary use teaches students about multiple word meanings, as well as the importance of choosing the appropriate definition to fit the particular context. Morphemic analysis is the process of deriving a word's meaning by analyzing its meaningful parts, or morphemes. Such word parts include root words, prefixes, and suffixes. Contextual analysis involves inferring the meaning of an unfamiliar word by scrutinizing the text surrounding it. Instruction in contextual analysis generally involves teaching students to employ both generic and specific types of context clues.
Fostering word consciousness
A more general way to help students develop vocabulary is by fostering word consciousness, an awareness of and interest in words. Word consciousness is not an isolated component of vocabulary instruction; it needs to be taken into account each and every day (Scott and Nagy, 2004). It can be developed at all times and in several ways: through encouraging adept diction, through word play, and through research on word origins or histories. According to Graves (2000), "If we can get students interested in playing with words and language, then we are at least halfway to the goal of creating the sort of word-conscious students who will make words a lifetime interest."
One principle of effective vocabulary learning is to provide multiple exposures to a word's meaning. There is great improvement in vocabulary when students encounter vocabulary words often (National Reading Panel, 2000). According to Stahl (2005), students probably have to see a word more than once to place it firmly in their long-term memories. "This does not mean mere repetition or drill of the word," but seeing the word in different and multiple contexts. In other words, it is important that vocabulary instruction provide students with opportunities to encounter words repeatedly and in more than one context.
Intentional instruction of vocabulary items is required for specific texts.
Repetition and multiple exposures to vocabulary items are important.
Learning in rich contexts is valuable for vocabulary learning. Vocabulary tasks should be restructured as necessary.
Vocabulary learning should entail active engagement in learning tasks.
Computer technology can be used effectively to help teach vocabulary.
Vocabulary can be acquired through incidental learning. How vocabulary is assessed and evaluated can have differential effects on instruction.
Dependence on a single vocabulary instructional method will not result in optimal learning.
It is often assumed that when students do not learn new vocabulary words, they simply need to practice the words some more. Research has shown, however, that it is often the case that students simply do not understand the instructional task involved (National Reading Panel, 2000). Rather than focus only on the words themselves, teachers should be certain that students fully understand the instructional tasks (Schwartz and Raphael, 1985). The restructuring of learning materials or strategies in various ways often can lead to increased vocabulary acquisition, especially for low-achieving or at-risk students (National Reading Panel, 2000). According to Kamil (2004), "once students know what is expected of them in a vocabulary task, they often learn rapidly."
Incidental vocabulary learning
The scientific research on vocabulary instruction reveals that most vocabulary is acquired incidentally through indirect exposure to words. Students can acquire vocabulary incidentally by engaging in rich oral-language experiences at home and at school, listening to books read aloud to them, and reading widely on their own. Reading volume is very important in terms of long-term vocabulary development (Cunningham and Stanovich, 1998). Kamil and Hiebert (2005) reason that extensive reading gives students repeated or multiple exposures to words and is also one of the means by which students see vocabulary in rich contexts. Cunningham (2005) recommends providing structured read-aloud and discussion sessions and extending independent reading experiences outside school hours to encourage vocabulary growth in students.
Did you know that typically, only 5% to 10% of instructional time is devoted to vocabulary instruction, yet students, especially struggling students and English learners (ELs), need between 12 and 14 exposures to words and their meanings to fully learn them (Durkin, 1978/79; Roser & Juel, 1982; Scott, Jamieson, Noel, & Asslin, 2003)? Teaching the meanings of important words before learning new content activates students' background knowledge and prepares them for learning and comprehending. In other words, teaching vocabulary provides the “Velcro” for new information to “stick to.”
What Research Says About Effective Vocabulary Instruction
Vocabulary instruction must be explicit. Explicit vocabulary instruction includes an easy-to-understand definition presented directly to students along with multiple examples and nonexamples of the target word, brief discussion opportunities, and checks for understanding.
Vocabulary instruction must include multiple practice opportunities for using words within and across subjects. That is, instruction must be extended over time with opportunities for students to hear, speak, read, and write words in various contexts. This builds students’ breadth and depth of vocabulary knowledge.
Vocabulary should be taught schoolwide and across all subject areas. Each subject has a unique set of vocabulary terms, and students need to know their meanings and how to use them in various contexts.
Word Selection
Instructional time is precious, and teachers are not able to address every unknown word students might encounter, so careful word selection is key. When deciding which words to target for explicit instruction, consider words that are

• 
  essential to understanding the main idea of the text or unit,
  
• 
  used repeatedly or frequently encountered across domains, and
  
• 
  not part of students’ prior knowledge.
  

ELs may require even more careful word selection and extensive vocabulary instruction because they may be learning conversational language and academic language at the same time.
The five activities described below are effective ways to teach vocabulary for all students, but especially for struggling students, students with learning disabilities, and ELs.
1. Essential Words Routine
Teachers use a simple graphic organizer to preteach the meanings of important words in about 5 minutes per word. During this routine, teachers introduce target words with definitions, visual cues, and examples. Students engage in immediate practice using the words through collaborative student turn-and-talk activities.
2. Frayer Model
One way to have students extend their knowledge of important words is through a Frayer model. This graphic organizer builds vocabulary and conceptual knowledge across content areas. The strategy requires students (not the teacher) to define a vocabulary word and then list its characteristics, examples, and nonexamples. Frayer models can be completed in collaborative groups using textbooks and other subject-matter materials while the teacher circulates around the classroom and assists students.
3. Semantic Mapping
Semantic maps visually display and connect a word or phrase and a set of related words or concepts. Implementing semantic map activities in your classroom will help students, especially struggling students and students with learning disabilities, recall the meanings of words and understand how multiple words or concepts “fit together.” Teachers will find that using a semantic map, combined with explicit instruction and practice opportunities, is an effective way of expanding students’ vocabulary and supporting their content knowledge.
4. Vocabulary Review Activities
Multiple opportunities to practice using new words is an important part of vocabulary instruction. In previous TCLD research studies, brief review activities were built into novel unit lesson plans to help students practice (and remember) the meanings of important words. Each of these activities takes 5 to 10 minutes and is easy to prepare.
5. Morphemic Analysis Routine
Explicit instruction of words is important, but it is impossible to teach all the unfamiliar words students will encounter. One way to help students develop strategies for approaching unfamiliar vocabulary is to teach morphemes (prefixes, roots, and suffixes). Students can be taught the following morphemic analysis routine to help them engage in independent word study.
A vocabulary is a set of familiar words within a person's language. A vocabulary, usually developed with age, serves as a useful and fundamental tool for communication and acquiring knowledge. Acquiring an extensive vocabulary is one of the largest challenges in learning a second language.
The first major change distinction that must be made when evaluating word knowledge is whether the knowledge is productive (also called achieve or active) or receptive (also called receive or passive); even within those opposing categories, there is often no clear distinction. Words that are generally understood when heard or read or seen constitute a person's receptive vocabulary. These words may range from well known to barely known (see degree of knowledge below). A person's receptive vocabulary is usually the larger of the two. For example, although a young child may not yet be able to speak, write, or sign, they may be able to follow simple commands and appear to understand a good portion of the language to which they are exposed. In this case, the child's receptive vocabulary is likely tens, if not hundreds of words, but their active vocabulary is zero. When that child learns to speak or sign, however, the child's active vocabulary begins to increase. It is also possible for the productive vocabulary to be larger than the receptive vocabulary, for example in a second-language learner who has learned words through study rather than exposure, and can produce them, but has difficulty recognizing them in conversation.
Productive vocabulary, therefore, generally refers to words that can be produced within an appropriate context and match the intended meaning of the speaker or signer. As with receptive vocabulary, however, there are many degrees at which a particular word may be considered part of an active vocabulary. Knowing how to pronounce, sign, or write a word does not necessarily mean that the word that has been used correctly or accurately reflects the intended message; but it does reflect a minimal amount of productive knowledge.
Words can be defined in various ways, and estimates of vocabulary size differ depending on the definition used. The most common definition is that of a lemma (the inflected or dictionary form; this includes walk, but not walks, walked or walking). Most of the time lemmas do not include proper nouns (names of people, places, companies, etc.). Another definition often used in research of vocabulary size is that of word family. These are all the words that can be derived from a ground word (e.g., the words effortless, effortlessly, effortful, effortfully are all part of the word family effort). Estimates of vocabulary size range from as high as 200 thousand to as low as 10 thousand, depending on the definition used.
Reading vocabulary
A person's reading vocabulary is all the words recognized when reading. This class of vocabulary is generally the most ample, as new words are more commonly encountered when reading than when listening.
Listening vocabulary
A person's listening vocabulary comprises the words recognized when listening to speech. Cues such as the speaker's tone and gestures, the topic of discussion, and the conversation's social context may convey the meaning of an unfamiliar word.
Speaking vocabulary
A person's speaking vocabulary comprises the words used in speech and is generally a subset of the listening vocabulary. Due to the spontaneous nature of speech, words are often misused slightly and unintentionally, but facial expressions and tone of voice can compensate for this misuse.
Writing vocabulary
The written word appears in registers as different as formal essays and social media feeds. While many written words rarely appear in speech, a person's written vocabulary is generally limited by preference and context: a writer may prefer one synonym over another, and they will be unlikely to use technical vocabulary relating to a subject in which they have no interest or knowledge.
Final vocabulary
The American philosopher Richard Rorty characterized a person's "final vocabulary" as follows:
All human beings carry about a set of words which they employ to justify their actions, their beliefs, and their lives. These are the words in which we formulate praise of our friends and contempt for our enemies, our long-term projects, our deepest self-doubts and our highest hopes… I shall call these words a person's "final vocabulary".
