The Weekly Vocabulary Word List

In many classrooms the predominant means of vocabulary instruction is weekly vocabulary word list. Pass it out on Monday; have students look up and write down definitions, make flashcards, do a crossword puzzle, do a word sort, write context clue sentences, etc. Then test on Friday. The problem is that this approach does not work. It’s ineffective and inefficient.

It’s ineffective.

Students memorize the list for the Friday test and forget half of them by the next week. “Rote memorization of words and definitions is the least effective instructional method resulting in little long-term effect (Kameenui, Dixon, Carine 1987).”

It’s inefficient.

Even if students were to remember all of the, say 20 words, on the weekly vocabulary word list for the entire school year, they would only have mastered 600 words. But, the American lexicon is over 800,000 words. The SAT® word bank is over 30,000. 600 words won’t make a dent in those numbers.

According to reading research, students need to learn 3,000 new words per year just to make year-to-year grade level progress (Honig 1983). So learning only 600 words is a very small drop in a very big bucket. But it is a bucket we desperately need to fill-especially for educationally disadvantaged students, whose “word poverty” (Louisa C. Moats) dooms them to the “Matthew Effect” (Keith Stanovich) in which the poorer tend to get poorer.

To teach students 3,000 words a year, students would have to learn 17 words each school day (3,000 words over 178 school days). However, classroom intervention studies suggest that only 8 to 10 words can be retained through direct instruction in one week (Stahl & Fairbanks, 1986). That works out to about 300 words per year-hardly enough.

So, if vocabulary word lists are ineffective and inefficient. What does work to teach those 3,000 words per year?

Three Effective and Efficient Methods of Vocabulary Instruction

1. Independent Reading

Let’s use Luis as our example. Reading 30 minutes per day for homework at a rate of 200 words per minute, for a total of 132 days (4 days per week in a typical school year), means that Luis would be exposed to 792,000 words (30 x 200 x 132). If Luis reads text at the recommended 5% unknown words* level of word recognition recommended by reading researchers (Stahl, 1999), this means that he would be exposed to 39,600 unfamiliar words per year (792,000 x .05). Because students learn between 5 and 10 percent of previously unknown words in a single reading (Stahl, 1999), Luis will have learned between 1,980 and 3,960 new words at home! Not to mention reading in class.

*That 5% unknown words level is critically important. If students read texts below their current reading levels, even lots of reading won’t result in measurable vocabulary growth (Carver, 1994).

2. Greek and Latin Word Parts

Reading researchers suggest that learning Greek and Latin word parts is an effective and efficient method for acquiring vocabulary (e.g., Anglin, 1993; Biemiller & Slonim, 2001). Over 50% of all academic vocabulary contains one or more Greek or Latin prefix, root, or suffix. Unlike memorizing vocabulary word lists, memorizing word parts produces enormous pay-offs because one prefix, root, or suffix may be a component of hundreds of words. Learning these word families provides significant utility for the reader, especially those word parts with the highest utility.

Just 9 prefixes constitute 75% of words with prefixes (White, Sowell, & Yanigihara, 1989). Comprehensive frequency studies have not been completed on roots; however, there is general consensus as to utility of a few hundred roots. There is less agreement on the value of teaching suffixes. Suffixes can often have vague meanings such as “the state of”; suffixes are often merely inflectional forms; they also tend to vary spellings. However, some study of suffixes that have specific meanings is certainly warranted. Check out a great list of Greek and Latin word parts for instruction here.

3. Tier One, Two, and Three Words (Beck et al., 2002)

Some words do not need to be taught. Tier One Words are high utility words that will become part of a student’s lexicon incidentally through oral language or reading. Tier Three Words are rare, specific-to-the-subject words that can sometimes be learned through effective application of context clues.

But some words do need to be taught. When reading a literature selection, certain words that are important to building comprehension or understanding of the text are essential to learn, especially if these words are used in a variety of forms, in other contexts or subjects of study, or are precise uses of generally-understood concepts. These are Tier Two Words.

For example, examine this sentence: The happy child was fortunate to have such a sunny disposition.

Tier One Words: happy, child, sunny

Tier Two Word: fortunate

Tier Three Word: disposition

The approach would be to assume that the reader knows the Tier One Words and leave the reader to use context clues to derive a basic understanding of the Tier Three Word. The Tier Two Word would be the word that deserves the instructional attention.

Accent Rule #1: Each word with two or more syllables has one syllable whose vowel is accented. For example, for-gét. Accents are very important to spelling rules. Accented means that the sound of that vowel is stressed, or louder, than those in other syllables.

Accent Rule #2: A long word may have more than one accent. The vowel that is stressed more or most is called the primary accent. The primary accent is key to many of the spelling rules. A second accented vowel is called the secondary accent.  For example, cón-ver-sá-tion. Very long words can have even more stressed vowel sounds, but only one primary accent.

Accent Rule #3: The primary accent is usually on the root before a double consonant. For example, for-gét-ting.

Accent Rule #4: Unaccented vowel sounds frequently have the soft /uh/ schwa sound, especially when there is only one letter in the syllable. All vowels can have the schwa sound. For example, the a in a-boút.

Accent Rule #5: The primary accent is usually on the first syllable in two-syllable words. For example, páy-ment.

Accent Rule #6: The primary accent is usually on the second syllable of two-syllable words that have a prefix in the first syllable and a root in the second syllable. For example, dis-tráct.

Accent Rule #7: For two-syllable words that act as both nouns and verbs, the primary accent is usually on the prefix (first syllable) of the noun and on the root (second syllable) of the verb. For example, pró-duce as a noun; pro-dúce as a verb.

Accent Rule #8: The primary accent is usually on the first syllable in three-syllable words, if that syllable is a root. For example, chár-ac-ter.

Accent Rule #9: The primary accent is usually on the second  syllable in three-syllable words that are formed by a prefix-root-suffix. For example, in-vést-ment.

Accent Rule #10: The primary accent is usually on the second  syllable in four-syllable words. For example, in-tél-li-gent.

Syllable Rule #1: Every syllable has a vowel. The common vowels are a, e, i, o, and u.

Syllable Rule #2: When the vowel is not at the end of a syllable, it has a short sound. The Vowel-Consonant (VC) and Consonant-Vowel-Consonant (CVC) patterns are called closed syllables. For example, bas-ket is a CVC-CVC word with the short vowels ă and ě.

Syllable Rule #3: When the vowel is at the end of a syllable, it has a long sound. The Consonant-Vowel (CV) and Consonant-Consonant-Vowel (CCV) patterns are called open syllables. For example, be-low is a VC-VC word with the long vowels ā and ō.

Syllable Rule #4: Vowel digraphs are paired vowels that have only one vowel sound. Usually the first vowel indicates the sound of the vowel digraph. For example, in the word boat, the vowel digraph is “oa” and the sound is /ō/. Usually keep vowel digraphs in the same syllable.

Syllable Rule #5: Base words are roots that form complete words. A root is the meaning-based syllable that may or may not connect to prefixes or suffixes. Usually keep the original spelling of the base word when connecting to prefixes and suffixes. For example, kick in kicking.

Syllable Rule #6: Compound words consist of two or three base words (roots that form complete words). Usually keep the original spellings of the base words in compound words. The spelling rules do not change the spelling of the base words. For example, bridesmaid.

Syllable Rule #7: An incomplete root is the meaning-based syllable that connects to prefixes and/or suffixes. Unlike a base word, the incomplete root is not a complete word. Both ending vowels and consonants can change when connecting to other roots and suffixes. Sometimes a vowel or consonant is either added or dropped. For example, vis in visible.

Syllable Rule #8: Keep the silent final “e” and the vowel before in the same syllable. The silent final “e” makes the vowel before a long sound if there is only one consonant in between the vowel and the “e”. For example, basement.

Syllable Rule #9: Vowel diphthongs are paired vowels that have two vowel sounds. For example, “au” in sauces. Like vowel digraphs, they stay in the same syllable.

Syllable Rule #10: Prefixes are meaningful word parts attached to the beginnings of words. More than one prefix can begin a word. For example, mis and under in misunderstand.

Syllable Rule #11: Suffixes are word parts attached to the endings of words. They can add meaning to the word or indicate a part of speech. More than one suffix can end a word. For example, on and al in seasonal.

Syllable Rule #12: Consonant digraphs, such as sh, and consonant blends, such as str, stay in the same syllable. For example, shallow and straighten. The /sh/ consonant digraph frequently changes to another consonant sound between different grammatical forms of the same root. For example, /sh/ to /k/ in musician and magic.

Syllable Rule #13: Keep the r-controlled vowels (ar, er, ir, or, and ur) in the same syllable. For example, er-ror.

Syllable Rule #14: Divide syllables between doubled consonants, for example for-gét-ting, unless the doubled consonant is part of a syllable included in a base word, for example ful-fill-ment.

Syllable Rule #15: Some short vowel sounds change to the soft /uh/ schwa sound with a different grammatical form of the same word. For example, in cónduct and conductor the “o” changes from a short vowel to a schwa.

Syllable Rule #16: Some long vowel sounds change to the soft /uh/ schwa sound with a different grammatical form of the same word. For example, in repeat and repetition the “e” changes from a long vowel to a schwa.

Syllable Rule #17: Some long vowel sounds change to the short vowel sound with a different grammatical form of the same word. For example, in nation and national the “a” changes from a long vowel to a short vowel.

Syllable Rule #18: Some silent consonants are pronounced when connected to different grammatical forms of the same root. For example, numb and number.

Syllable Rule #19: Many Greek and Latin prefixes change their spellings to match the roots to which they attach in order to make pronunciation easier. For example, in and mobile becomes immobile. These “chameleons” can change either their consonant or vowel spellings.

Syllable Rule #20: Many Greek and Latin suffixes are morphemes, which means that the word part is meaningful. For example, viewable. Other suffixes serve as inflections, which means that the suffix helps change the part of speech, but does not add meaning to the word. For example, started.

Since reading remains the chief vehicle that we use to access this knowledge, we had better get good at it. Knowing vocabulary is, of course, one of the keys to reading. The precise definitions of vocabulary words are the lower level gatekeepers  that allow readers access to the higher level thinking skills.

But, some may be thinking… aren’t all words subject to individual interpretation? To some degree, yes. However, words do have a collective consciousness of meaning. They do connect to objective realities. In other words, words are not totally subjective. Words must be denotatively internalized and connotatively applied with a good deal of accuracy and skill to properly access information the way the author intends. Only when the reader understands the author’s intentions can higher order thinking skills be then applied to the text.

Although that author-reader connection is a two-way street, the relationship should be weighted heavily on the side of the author. It is the author’s thoughts that we are trying to interpret, not ours per se. An author chooses words carefully because of their precise meanings and the connotations/feelings that the collective readers commonly will understand.

So, memorizing words with precise denotative and connotative definitions is important. Sloppy use of our language inhibits effective communication and leads to misunderstandings. So, what’s the bottom line here? What’s the application for teacher and learner? It is better to teach and learn fewer words with greater precision, than many words with less precision. Two vocabulary strategies assist in this effort: The Vocabulary Ladder and Semantic Spectrums.

The Vocabulary Ladder

Students draw a graphic representation of a ladder with five rungs. They take notes in between the rungs from each of the guiding prompts (in boldface). Begin with a clear, simple, and concise dictionary definition and work students up the ladder via class and teacher brainstorming and reference to appropriate text.

Example Vocabulary Word: democracy

Full Understanding

-It’s important because… it’s the foundation of our government.

-It’s different than… a republic because… a republic has a Constitution.

-It’s the same as… a republic because… both have citizens who are allowed to vote.

-Specific examples of it would be… direct democracy like a club, representative democracy like our Student Council.

-It’s an example of the following… ways decisions are made in governments and organizations.

-The definition is… rule by the people.

Basic Understanding

Semantic Spectrums

Students draw a number line with one end labeled Extreme and the other end labeled Opposite  Extreme. The object is to list words in their connotative order along the spectrum of meaning. Select two vocabulary words for this activity that students fully understand that are antonyms. For example, hot and cold. Have students brainstorm synonyms to each word at the ends of the spectrum and problem-solve via consensus as to where to list each new word by degree of meaning. Select one or two unknown vocabulary words that will fit along this spectrum and read a clear, simple, and concise dictionary definition of each. Assist the students’ decision-making as to where to place these new words. Have the students write down their definitions below the spectrum.

Example Vocabulary Words: even-tempered and vicious

Extreme kind-hearted/nice/warm/even-tempered/cool/mean/cruel/vicious/hateful Opposite Extreme

But why learn and practice context clue strategies to problem-solve the meanings of unknown words? Wouldn’t it be more precise to use the dictionary? No. The dictionary is a fine tool and should be used to look up words that are critical to the comprehension of any reading. However, the dictionary is not a practical tool for reading at the 5% unknown words reading level. Often, the definition frequently does not fit the connotative meaning of the word as used in the reading passage. Additionally, there are often multiple definitions—which one fits? Context always determines meaning. Also, looking up one in every twenty words adversely affects comprehension. Time spent looking up words is reductive. The few minutes it takes to look up and internalize the definition could be better spent reading more text, because the more words read provides more exposure and practice—the keys to efficient vocabulary acquisition.

So, learning and practicing context clue strategies makes sense. Context clue strategies can be internalized with sufficient practice and can be flexibly applied by skillful readers to figure out the meaning of many unknown words without adversely impacting comprehension. The best way to apply context clue strategies is to learn the problem-solving strategies detailed in FP’S BAG SALE. When readers come to an unknown word, they apply the relevant steps of the FP’S BAG SALE strategy to get a good clue about the meaning of an unknown word.

Flexibility is key to using context clue strategies. Multiple strategies provide multiple ways of problem-solving. Good readers learn to quickly sort through the options and select the strategy or strategies that works best. They also accept the fact that context clue strategies don’t always work and that understanding every single word is not necessary for the purpose of reading—effective meaning-making.

Initially, readers should follow the steps of the FP’S BAG SALE context clues approach in order to problem-solve the meanings of unknown words. Then, through teacher modeling and guided practice, students should learn to efficiently “hunt and peck” for clues to meaning by applying the individual steps.

FP’S BAG SALE

Finish the sentence. See how the word fits into the whole sentence.

Pronounce the word out loud. Sometimes hearing the word will give you a clue to meaning.

Syllables–Examine each word part. Word parts can be helpful clues to meaning.

Before–Read the sentence before the unknown word. The sentence before can hint at what the word means.

After–Read the sentence after the unknown word. The sentence after can define, explain, or provide an example of the word.

Grammar–Determine the part of speech. Pay attention to where the word is placed in the sentence, the ending of the word, and its grammatical relationship to other known words for clues to meaning.

Synonym–Sometimes an unknown word is defined by the use of a synonym. Synonyms appear in apposition, in which case commas, dashes, or parentheses are used. Example: The wardrobe, or closet, opened the door to a brand new world.

Antonym–Sometimes an unknown word is defined by the use of an antonym. Antonym clues will often use Signal Words such as however, not, but, in contrast Example: He signaled a looey, not a right turn.

Logic–Your own knowledge about the content and text structure may provide clues to meaning. Logic clues can lead to a logical guess as to the meaning of an unknown word. Example: He petted the canine, and then made her sit up and beg for a bone.

Example–When part of a list of examples or if the unknown word itself provides an example, either provides good clues to meaning. Example clues will often use Signal Words such as for example, like, such as Example: Adventurous, rowdy, and crazy pioneers all found their way out West.

How to Practice Context Clue Strategies

Select passages from the textbook or literature that contain unknown words. Demonstrate how to problem-solve the meaning of the unknown words by doing a “Think-Aloud” of the FP’S BAG SALE strategies. Select words that can be specifically determined by each step of the process. Also, select words that have no helpful context clues to show how the process is not fool-proof.

Select passages from the textbook or literature, scan into a word processor and delete every twentieth word, skipping articles, conjunctions, and prepositions. This is known as a CLOZE passage. Then have the reader use the FP’S BAG SALE strategies to guess the meaning of the deleted words. Compare reader answers with the original words and award points for correct answers. Of course, synonyms are fine and will promote rich denotative and connotative word discussions.

Select unknown words that contain high frequency word parts as described in the next article titled “How We Learn Vocabulary from Word Parts Part IV.” Use sentences and three-sentence paragraphs that include these words as class openers. Good readers make use of structural analysis to problem-solve the meaning of unknown words. Although not technically context clues, word parts—both morphological (meaning-based) and grammatical (for example, parts of speech and inflections)—are essential components to vocabulary acquisition.

So, I’ve covered the first key to efficient vocabulary acquisition in Parts II and III: wide reading with effective context clue strategies. This is the key to help readers thrive. The next article in this series, “How Wise Learn Vocabulary from Word Parts Part IV,” will explain the need for the second key to efficient vocabulary acquisition: structural analysis and academic language, and will detail the words necessary for skillful readers to thrive in the world of academic reading.

To understand how we learn vocabulary, it is helpful to examine how children build their bank of words through oral vocabulary acquisition. By age five, children have gained up to a 10,000 word vocabulary including common inflections such as suffixes. How did children who may only have one year of pre-school and one year of kindergarten gain such an extensive vocabulary? Exposure and practice. Children are bombarded with oral language from parent “oohs and ahs” to simple conversations to the background noises and words of daily life. In homes that are rich in communication, children before the age of four have heard 45 million words. In contrast, in homes that do not provide rich communication, children before the age of four have heard only 13 million words (Hart and Risley 1996).

Noam Chomsky’s theory of an innate universal grammar explains how children are able to apply words into meaningful phrases and sentence structures in an efficient manner. Children fit new words into the morphological (meaning) and syntactical (grammatical) context of old words and so language acquisition compounds. New words are not learned in isolation, but in the context of what has been previously mastered and practiced. But why do children learn words so quickly while adolescents and children learn words at such a slower rate? Is it because “you can’t teach a dog new tricks” or a change in brain development? No. Primarily the reasons are exposure and practice.

After the first 10,000 words, the rest are rare words, and these play a critical role in academic reading. The utility of our academic vocabulary is determined not by the first 10,000 words, but by how many of the rare words we understand (Hart and Risley 1996). The next 20,000 words learned by most college-educated adults takes about twenty years to acquire. Exposure to and practice of more sophisticated words is much less frequent than the “meat and potatoes” words of childhood. A brief example may be helpful. A child learns the word hungry at a very early age. The word has two syllables and is phonetically regular. A late teen or early adult may learn the word famished. The word has two syllables and is phonetically regular. The difference in word acquisition between hungry and famished is influenced by exposure. A child first hears the word hungry early in life and most every day thereafter from parents or from television. An adult may hear or read the word famished once every few months. The difference in word acquisition between hungry and famished is also influenced by practice. The word hungry is a high utility word. Both children and adults say this word often in all of its inflected forms. The word famished is just not said as often.

So, beyond the first 10,000 words of life, do we continue to learn most of our vocabulary through skillful listening? No. A few interesting facts will prove this point. The first 1,000 words acquired by children constitute the vast majority of words used by and heard by even the most educated adults on a daily basis. Watching and listening to thirty minutes of Sesame Street exposes the viewer to an average of only one word beyond the highest frequency 1,000 words. Watching and listening to the nightly news for the same amount of time exposes to viewer to only nineteen of these key words (adapted from Hayes and Athens 1988).

However, in contrast, reading provides a much higher exposure to words beyond the most frequently used 1,000 words. For example, reading a challenging comic book for thirty minutes exposes the reader to fifty-three of these words. Reading a challenging book for the same amount of time exposes a reader to seventy-five. So, reading challenging text certainly provides a greater opportunity to expand one’s vocabulary through exposure and practice than does listening alone.

Now, how can we make wide reading of challenging text more efficient for vocabulary acquisition? First of all, because exposure to the right words is so critical, it is essential to carefully choose reading text for optimal practice. According to reading specialists, reading text that has 5% unknown words should be our target reading text to maximize vocabulary acquisition. Readers can maintain good comprehension while exposing themselves to 300 unknown words in thirty minutes of reading. This assumes an average reading rate of 200 words per minute with 6,000 words read in thirty minutes, of which 5% unknown words would be 300. Assuming that a reader would “naturally” acquire 5% of these unknown words via unrefined use of context clues, the reader would have a net gain of 15 new words from the reading session. Thus, four days of thirty minutes (two hours) reading practice would better a reader’s vocabulary by 60 words—substantially better than acquiring 20 new words each week by memorizing a list of words. Also, the prospect of additional practice of these words is much higher than that of the random word list memorized for the Friday test.

How can you pick a book to read that has 5% unknown words? Choose a book of any genre and count the number of words on any complete page found near the beginning of the book and multiply that number by 3. Read a page toward the beginning of the book, counting the number of unknown words. A good guideline would be “if you can’t define it with a synonym, antonym, or example,” it is unknown. Then, read a page near the middle of the book and continue the count. Finally, read a page near the end of the book and finish the count. Divide the total number of unknown words by the total number of words found on the three pages. The result will be the percentage of unknown words. Anything within the 4-6% range is acceptable. For example, a reader counts the number of words on a page and arrives at 225. 225 x 3 = 750. After reading the three pages, the amount of unknown words totals 30. 30.00 divided by 750 = .05, or 5%.

Additionally, reading specialists would argue that the 5% retention rate can be doubled to 10% by applying refined context clue strategies. Doubling the number of words acquired from thirty minutes reading each day would produce a net gain of 30 new words from each reading session or 120 words each week, considering four such sessions. 120 words per week, multiplied by 33 weeks in a school year produces 3960 new words in a school year—surpassing the target for the 3,000 new words that reading specialists suggest are necessary to make grade level growth in vocabulary development.

In order to refine context clue strategies, readers need to learn the types of context clues that work most often to help readers figure out unknown words. By examining surrounding sentence and word clues according to these context clue categories, more unknown words can be figured out. So, grab a second cup of coffee for the next article, Part III, and learn how to teach the refined context clue strategies that will double the amount of words that readers acquire through reading challenging text.

The problem with the typical vocabulary instructional practice described above is not necessarily the content, nor the teaching approach. Indeed, the problem is one of effectiveness. According to research, “Rote memorization of words and definitions is the least effective instructional method resulting in little long-term effect (Kameenui, Dixon, Carine 1987).” 

If students remember all 20 words, each week for the entire school year, they will have mastered 600 words. Now, realistically, if teachers got students to remember half of those words by the end of the year (think standardized test), most would be pleased. That leaves 300 words mastered per school year.

But, the American lexicon is over 800,000 words, and the SAT® word bank is over 30,000 words. Students need to learn 3,000 new words per year just to make one grade level progress (Honig 1983). Learning 300 words per year is a very small drop in a very big bucket. So, not only is rote word memorization ineffective, it is also inefficient. 

Additionally, teaching vocabulary isolated from reading and spelling instruction ignores the structural components of words: phonics (decoding) and spelling (encoding), as well as the meaning-making purpose of words: understanding (comprehension) and communication (syntax, tone, clarity, etc).

At this point, frustration sets in… Even the most dedicated teachers might be thinking “Why teach vocabulary at all, then? Maybe students will just learn it on their own” or “I can’t spend any more time, teaching more words, than I already do. After all, I have reading skills, literary analysis, spelling, grammar, writing etc. to teach, as well” or “If I ignore it, it just might go away.”

For thick-skinned teachers who have made it to this point in the article, there is hope. Students can master the 3,000 new words this year that reading experts agree are necessary to achieve two-year-growth in reading levels. Your teaching can impact these levels of vocabulary acquisition. And you don’t have to spend much more class time to teach vocabulary efficiently. So what are the most efficient strategies? I call the two most efficient strategies to vocabulary acquisition 1. Efficient Reading and 2. Efficient Word Study.

Briefly defined, Efficient Reading involves re-orienting your homework assignments to focus on independent level reading with targeted context clues practice. The downsides? This approach requires some additional class time allocated to context clues instruction, additional record-keeping/accountability, and elimination of most other written homework assignments by default. The upsides? Increased vocabulary and comprehension, as well as a high likelihood of creating life-long readers. 

Briefly defined, Efficient Word Study involves teaching the survive words: the academic language, literary terms, and those words essential to the understanding of literature selections and the thrive words: the morphological prefixes, roots, and suffixes. The downsides? You will have to spend a bit more class time teaching “deep-level” vocabulary techniques for the survive words. You will also have to spend a bit more class time on Greek and Latinates/word analysis for the thrive words. The upsides? Increased vocabulary and word recognition skills that complement context clue skills. 

In the next four articles in this series on vocabulary development I offer the rationale and specific teaching strategies and resources for efficient reading and efficient word study. “How to Teach Efficient Reading Part II,” “How to Double Vocabulary Acquisition Part III,” “How We Learn Vocabulary from Word Parts Part IV,” and How to Teach the Most Efficient Word Parts Part V” will give every teacher the tools to enrich their students’ vocabularies.
