STR Vocabulary Development 2 — Questions and Answers
Question 1: Which type of vocabulary instruction has the strongest research support for improving reading comprehension?
- Having students copy dictionary definitions for all unknown words
- Explicit, rich instruction in a small number of high-utility words with multiple exposures (Correct answer)
- Encouraging wide independent reading as the sole vocabulary-building strategy
- Requiring students to use new words in a sentence the day they are introduced
Correct answer: Explicit, rich instruction in a small number of high-utility words with multiple exposures
Research supports explicit, rich vocabulary instruction that provides deep processing and multiple encounters with a limited set of high-utility words, which leads to durable word learning.
Beck, McKeown, and Kucan's framework demonstrates that robust vocabulary instruction involves selecting high-utility Tier 2 words, providing student-friendly definitions, offering multiple meaningful exposures across contexts, and engaging students in deep processing such as comparing and classifying. Dictionary copying produces superficial word knowledge. Wide reading builds vocabulary incidentally but does not reliably teach precise academic word meanings. One-day exposure is insufficient for durable learning.
Question 2: Isabel Beck's Tier 2 words are best described as:
- Basic words known by most young children, such as table and run
- High-frequency academic words useful across many contexts, such as analyze and fortunate (Correct answer)
- Domain-specific technical vocabulary unique to one subject, such as photosynthesis or polygon
- Words found only in literary texts and rarely encountered in speech
Correct answer: High-frequency academic words useful across many contexts, such as analyze and fortunate
Tier 2 words are high-frequency, high-utility words that appear across many content areas and academic texts but are not typically part of everyday conversational vocabulary.
Beck's three-tier vocabulary framework categorizes words by frequency and utility: Tier 1 are basic, high-frequency words known through oral language; Tier 2 are general academic vocabulary appearing across disciplines such as analyze, evident, and reluctant; Tier 3 are low-frequency, domain-specific technical words. Tier 2 words get the most instructional attention in the STR framework because they appear in tests, academic texts, and content-area instruction, yet students rarely learn them through conversation.
Question 3: A teacher introduces the word 'persistent' by providing its definition, showing it used in two different sentences, asking students to compare a persistent person to a lazy one, and then having students rate their own persistence. This approach exemplifies:
- Incidental vocabulary learning through context
- Tier 3 technical vocabulary instruction
- Rich, robust vocabulary instruction with deep processing (Correct answer)
- Direct phonics instruction applied to multisyllabic words
Correct answer: Rich, robust vocabulary instruction with deep processing
This multi-faceted approach combining definition, contextual examples, comparison, and personal connection characterizes the rich, robust vocabulary instruction recommended by Beck and colleagues.
Robust vocabulary instruction involves more than defining a word: students encounter it in multiple contexts, engage in higher-order processing, and connect it to their own experience. This produces word knowledge that is flexible, precise, and long-lasting. Incidental learning is unplanned; Tier 3 instruction would be for specialized technical terms; phonics instruction focuses on decoding, not meaning.
Question 4: Which vocabulary strategy helps students use context clues to infer word meaning?
- Pre-teaching vocabulary before reading
- Semantic mapping of related words
- Teaching students to examine surrounding sentences and signal words for meaning clues (Correct answer)
- Using a word wall to display high-frequency words
Correct answer: Teaching students to examine surrounding sentences and signal words for meaning clues
Context clue strategies teach students to use the words and ideas surrounding an unknown word, such as definitions, examples, and contrast signal words, to infer meaning during reading.
Context clue instruction teaches students to identify types of clues authors embed in text: definition clues, example clues, contrast clues with signal words like 'however' or 'unlike', and inference clues requiring integration of surrounding ideas. This is a metacognitive strategy that gives students an independent tool for learning vocabulary during reading. Pre-teaching is a teacher-directed activity, not a student strategy. Semantic mapping deepens knowledge of known words. Word walls support high-frequency word recognition, not inferential meaning-making.
Question 5: Word consciousness refers to:
- Awareness of a word's phonological properties only
- An interest in and awareness of words, their meanings, and their uses (Correct answer)
- The ability to decode multisyllabic words quickly and accurately
- Memorizing definitions of Tier 3 academic words
Correct answer: An interest in and awareness of words, their meanings, and their uses
Word consciousness is a disposition toward noticing, appreciating, and being curious about words, including their origins, nuances, and power, which motivates vocabulary growth.
Word consciousness encompasses awareness of and interest in words, noticing when an author chooses a particularly vivid or precise word, curiosity about word origins, appreciation for wordplay and connotations, and understanding of how word choice affects meaning and tone. Teachers who foster word consciousness create language-rich environments with word walls, word of the day, etymology discussions, and celebrations of interesting word use.
Question 6: Which instructional approach builds morphological awareness to support vocabulary development?
- Having students memorize 20 vocabulary words per week using flashcards
- Teaching common prefixes, suffixes, and roots so students can analyze unfamiliar words (Correct answer)
- Using pictures and gestures to teach all new vocabulary words
- Providing a class glossary of technical terms at the start of each unit
Correct answer: Teaching common prefixes, suffixes, and roots so students can analyze unfamiliar words
Morphological awareness instruction teaches students the building blocks of words, empowering them to analyze and infer the meaning of tens of thousands of derived words.
Morphological awareness, which is understanding how morphemes combine to form words, is one of the most powerful vocabulary-building tools available to students, particularly in upper elementary and middle school. Research shows that 60 to 80 percent of English academic vocabulary consists of morphologically complex words. Teaching high-utility prefixes, suffixes, and Latin and Greek roots gives students a generative tool for analyzing novel words. Flashcard memorization produces shallow, temporary knowledge. Glossaries and pictures are useful supplements but are not generative strategies.
