Alabama Foundations of Reading (890)

Vocabulary knowledge is strongly correlated with reading comprehension. Students need robust vocabularies to understand what they read and to express their ideas in writing.

Listening and speaking vocabularies develop first; reading and writing vocabularies develop as students become literate. Receptive vocabulary (listening and reading) typically exceeds expressive vocabulary (speaking and writing).

Isabel Beck and colleagues proposed organizing vocabulary into three tiers:

Research identifies several principles for effective vocabulary instruction:

Effective strategies include:

Students learn most vocabulary incidentally through reading, listening, and conversation. However, intentional instruction accelerates vocabulary growth, particularly for struggling readers and English learners.

Effective programs balance wide reading for incidental learning with direct instruction of strategically selected words.

Word analysis involves using knowledge of word structure to determine pronunciation and meaning. Skilled readers use multiple strategies to analyze unfamiliar words.

Structural analysis involves examining word parts—roots, prefixes, suffixes, and inflections—to determine meaning. Students learn to recognize meaningful word parts and use them to decode and comprehend unfamiliar words.

Context clues are hints in the surrounding text that help readers infer word meanings. Types of context clues include:

General context: The overall meaning of the passage suggests the word's meaning

Teaching students to use context clues strategically improves comprehension. However, context clues are not always reliable; students should verify inferences using other sources.

Students need instruction in using dictionaries and glossaries effectively:

Alphabetical order for locating entries

Guide words for efficient searching

Pronunciation keys for determining pronunciation

Multiple definitions and selecting appropriate meanings

Etymology for understanding word origins

Usage labels indicating formality or domain

Morphology is the study of word structure—how words are formed from meaningful units called morphemes.

A base word is a free morpheme to which affixes can be added (happy + un- = unhappy).

A root is a morpheme that carries core meaning but may not stand alone. Many English roots derive from Latin or Greek:

Common Latin roots:

Common Greek roots:

The four most common prefixes (un-, re-, in-/im-, dis-) account for over half of all prefixed words in English.

Common prefixes:

Common suffixes:

Research demonstrates that morphological awareness contributes to:

Word reading accuracy

Vocabulary knowledge

Spelling ability

Reading comprehension

Instruction in morphology helps students decode multisyllabic words and infer meanings of unfamiliar vocabulary.

Effective morphology instruction includes:

Teaching common prefixes, suffixes, and roots explicitly

Showing how affixes change word meaning and part of speech

Providing practice identifying word parts in context

Connecting morphology to spelling patterns

Using word webs and matrices to show word relationships
