In this series of five articles, I have attempted to share what instructional approaches do and do not promote efficient vocabulary acquisition. In “The Problem with Most Vocabulary Instruction Part I,” I debunked the inefficient word list method of vocabulary instruction. In “How We Learn Vocabulary from Reading Part II,” I showed how wide reading at a reader’s challenge level of 5% unknown words is a much more efficient means to increase vocabulary. In “How to Double Vocabulary Acquisition from Reading Part III,” I detailed how to teach context clue strategies to help readers increase their percentage of word acquisition through reading. In “How We Learn Vocabulary from Word Parts Part IV,” I provided a rationale for teaching the word parts that are keys to academic vocabulary and listed the highest utility word parts.

This article will demonstrate how to teach these words with a variety of effective instructional strategies.

Word Part Brainstorming

One of the most effective strategies for learning and practicing word parts is to have students build upon their previous knowledge of words that use the targeted word parts. Building student vocabularies based upon their own prior knowledge ensures that your example words will more likely be within their grade-level experience, rather than arbitrarily providing examples beyond their reading and listening experience.

After introducing the week’s word parts and their definitions (I suggest two prefixes, three roots, and two suffixes per week), ask students to brainstorm words that they already know that use each of the word parts. Give students two minutes to quick-write all the words that they know that use the selected prefix, root, or suffix. Then, ask students to share their words in class discussion. Quickly write down and define each word that clearly uses the definition that you have provided. Ignore those words that use the word part, but do not clearly exemplify the definition that you have provided. Require students to write down each word that you have written in their Vocabulary Journals. Award points for all student contributions.

Inventive Writing

After introducing the week’s word parts and their definitions (I suggest two prefixes, three roots, and two suffixes per week), ask students to invent words that use each word part in a sentence, that uses context clues to show the meaning of each nonsense word. Encourage students to use “real” word parts to combine with each targeted word part to form multi-syllabic words. Award extra points for words used from prior week’s words.

For variety, require students to write in different genre. Examples: brief narratives, classified ads, game directions, how-to paragraphs, dialogs, journals, classroom rules, advice columns

Word Art

After teaching numerical word parts, for example, bi, multi, non and body parts, for example, pod, corp, ocul, have the students design and illustrate their own Word Part Monsters, using these word parts. Students draw the monster on the front and label the name of their monster on the back, for example, Pyrcapbipod (fire-headed-two-foot). Number and post these creations picture-side-up and have the students walk around the room and identify the names of these monsters. Read the answers and have students correct. A sure-fire Halloween lesson plan! Thanks to Barbara Baker, of Amador County Unified, CA for the genesis of this idea.

The Quick Picks Game

Divide your students into two groups and select one student as the host. Have the students spread out their cards and then race to pick up the word part that matches definition that the host announces (or the other way around). The first group with all students holding up the correct word part wins a point. Note for the host: Many word parts have similar definitions, so try to pick definitions that can be identified by only one word part. Also, it is certainly fair for group members to help each other out.

Put-Togethers

Have students spread out their cards into prefix, root, and suffix groups. The object of the game is to put together these word parts into real words within a given time period. Students can use connecting vowels. Students are awarded points as follows:

1 point for each prefix—root combination

1 point for each root—suffix combination

2 points for a prefix—root combination that no one else in the group has

2 points for a root—suffix combination that no one else in the group has

3 points for each prefix—root—suffix combination

5 points for a prefix—root—suffix combination that no one else has.

Game can be played timed or untimed.

Spell and Define Challenge Bowl          

Divide your students into two groups and select one student as the host. Have the students spread out their cards. The host says any word part chosen at random and the first student must first spell then define the word part. If the student is unsure of either the spelling or definition, he or she may use a “lifeline” to ask another group member for assistance, but only once per game. If the student gets both the spelling and definition correct, he or she remains standing; if incorrect, the student takes a seat and the next word goes to the opposing team. The team with the last student standing wins.

Concentration

Divide your students into groups of four and tell students to select two students whose printed flashcards look very different from each other. Have one of these students lay out the cards word part side up and the other student lay out the cards definition side up. Students choose cards to pair the word part with its definition. If a student selects a correct match, that student chooses again; if not, the next student selects, etc. The winner has the most matches.

Baseball

Divide your students into two teams and establish four bases. When in the field, students sit in seats; when “up” the students stand in line waiting their turn to bat. Teacher selects either a single, double, triple, or home run card first. Then, the teacher announces the word part and the batter must give the definition within five seconds or the batter is out. Mix it up by giving definitions and having students come up with the matching word parts. Three outs per each team per inning. Hint: Have many more singles cards than the others.

Knock-Out

Have all students stand and quiz each student with a word part or definition. If the student gets it right within five seconds, the student remains standing; if not, the student sits. Last one standing wins the game.

Grammar/Mechanics, Reading Greek, Latin, morphemes, vocabulary, vocabulary instruction, word parts

In this series of articles, I have attempted to share what instructional approaches do and do not promote efficient vocabulary acquisition. In “The Problem with Most Vocabulary Instruction Part I,” I debunked the inefficient word list method of vocabulary instruction. In “How We Learn Vocabulary from Reading Part II,” I showed how wide reading at a reader’s challenge level of 5% unknown words is a much more efficient means to increase vocabulary. And, in “How to Double Vocabulary Acquisition from Reading Part III,” I detailed how to teach context clue strategies to help readers increase their percentage of word acquisition through reading.

In this article, I provide a rationale for teaching the word parts that are keys to academic vocabulary. Additionally, I will share the high utility word parts in priority order that get readers the most “bang for their collective bucks.

The morphological (meaning-based) word parts that form the basis of English academic vocabulary are primarily Greek and Latinates. Prefixes and roots carry the bulk of important word meanings; however, some key suffixes are important, as well. Over 50% of multi-syllabic words beyond the most frequently used 10,000 words contain a Greek or Latin word part. Since Greek and Latinates are so common in our academic language, it makes sense to memorize the highest frequency word parts.

Memorizing high utility Greek and Latin word parts is a very efficient tool to acquire academic vocabulary. Learning the most common word parts unlocks the keys to thousands of academic words which use one or more of those word parts. Even knowing just one word part will provide a clue to meaning of an unknown word. For example, a reader may not understand the meaning of the word bicameral. However, knowing that “bi” means two certainly helps the reader gain a sense of the word, especially when combined with other context clues such as synonyms, antonyms, logic-based, and example clues. For example, in the following sentence the example clue, “checks and balances,” combines with the word part clue, “bi” (meaning two) help the reader problem-solve the meaning of the unknown word: The bicameral legislature provided important checks and balances.

Word part clues are highly memorable because readers have frequent exposure to and practice with the high frequency word parts. Additionally, they are memorable because the simple to understand use of the word part can be applied to more complex usages. For example, “bi” means two in bicycle, just as it means two in bicameral or biped. Analogy is a powerful learning aid and its application in academic vocabulary is of paramount importance.

So here are the highest utility word parts that will assist readers in vocabulary acquisition, especially when paired with wide reading, using refined context clues. The final article in this series, “How to Teach the Most Efficient Word Parts Part V,” will demonstrate how to these these words in a variety of effective instructional strategies.

In “The Problem with Most Vocabulary Instruction Part I,” I debunked the inefficient word list method of vocabulary instruction. In “How We Learn Vocabulary from Reading Part II,” I showed how reading is a much more efficient means to increase vocabulary. I explained how reading challenging text at the 5% unknown word level provides optimal exposure to and practice of words beyond those gained through oral acquisition during the first five years of life. I also detailed how to select books at this specific reading level. Finally, I cited reading specialists who claim that teaching specific context clue strategies can help readers double their vocabulary acquisition. I saved the “how-to’s” for this article.

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.

In Part I, I debunked the word list method of vocabulary instruction. The give-them-twenty-words-on-Monday-and-test-on-Friday approach is as American as apple pie, but is also highly inefficient. The English lexicon of over 800,000 words is just too vast to rely on rote memory of individual words. I suggested that the two most efficient methods of vocabulary instruction consist of 1. wide reading with refined context clues strategies and 2. word part memorization. This article will discuss how we learn vocabulary from reading, Part III in the series will explain how to refine the use of context clues to double the rate of word acquisition from reading, Part IV will examine how we learn vocabulary from word parts, and Part V will share how to teach and learn the essential word parts in the most efficient manner.

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.

Don’t read this article if you susceptible to thin-skin teacher disease. The typical vocabulary instruction in many classrooms includes passing out a “big words” list of 20 vocabulary terms on Monday and quizzing on this list on Friday. Starting to cringe? And now the “buts” start to formulate. Some of the “buts” will focus on the content of the list: “But half of those words are from the literature selections this week” or “But half of those words are SAT® words” or “But half of those words are grade-level words that my students should know.” Other “buts” will focus on the learning process: “But I make them write out each word ten times” or “But I make them create flashcards for each word” or “But I have them underline the prefixes and suffixes and circle the roots.” The last “but” is all-too pervasive, if some of us are truly honest about why we really teach what and how we teach: “But that’s what and how I learned, and I turned out okay.”

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.

Memorizing the definitions of the most common Greek and Latin prefixes, roots, and suffixes will exponentially expand your reading vocabulary. Academic reading, especially in the social sciences and natural sciences are filled with words with Greek and Latin word parts. The verbal section of the SAT I is largely comprised of academic words having these word parts. Knowing even one word part of an unknown word greatly enhances the reader’s ability to accurately and efficiently use surrounding context clues to figure out the meanings of these words. You will also increase your spoken and written proficiency by using Greek and Latin prefixes, roots, and suffixes. But, outside of becoming fluent in Greek and Latin, which Greek and Latin word parts have the highest frequency?

Most Commonly-Used Prefixes
