The essence of Meaning Vocabulary
Instruction:
1. Helping students learn new
concepts or things and the words
that signify those things.
2. Helping students learn new words
for concepts and things they
already know.

The Word things

The essence of all teaching is
teaching the things of the world: i.e.,
Objects: cells or hieroglyphics,
Feelings: remorse or empathy,
Actions: revolutions or osmosis, &
Ideas: mass or equity.

Reason 1 For Teaching Things &
Words
Learning new things and their words
changes or increases our perception
and organization of the world

Linus Pauling
If I couldn’t find a place in my mind
for some new thing, I would change
my picture of the world until I
understood where it fit. Or I would
throw it out and come back to it later.

Reading comprehension mandates
knowing the meaning (thing)
associated with words in the text

When students do not know meanings
of words used in a written text,
comprehension often decreases.

Words
Learning new things and words
facilitates students’ abilities to use
words judiciously— which is much
valued in our society

Four Goals of Teaching
Things & Words
1
Facilitate student’s innate curiosity
about things & words and joy in
learning them by:
a. increasing word consciousness
b. providing ongoing fun activities about
words
47

2 Directly teach students those
things & words necessary for
school and learning
3 Develop students’ skills and
strategies for lifelong learning of
things & words

Goal 1
The first goal is to reinforce the idea
that learning new things (new ideas,
new objects, new actions, and new
feelings) is natural, interesting and
stimulating—indeed, usually fun.

– Hard words you recently saw
• Provide ongoing fun activities about
words
– Puns, games, derivations of words
– Comics, comic strips

short tight curls round a shining calvity, though he

Goal 2. Direct Teaching of
Meanings of Specific Words
THINK!
Are you teaching a new word for an old
thing, or teaching a new thing, to
which you will also attach a word?

Selecting Words to Teach
• Beck, McKeown, & Kucan Tier 1, 2 & 3 Words
– Tier 1—easy words that are part of everyday
speaking (do not teach)
– Tier 2—high frequency for mature language
users and found across variety of domains:
e.g., coincidence, absurd, fortunate
– Tier 3—low frequency words with specific
meanings, often technical: e.g., isotope, lathe,
refinery

Direct Teaching of Words—
RINS
1. Define the thing’s Relevant
attributes
2. State its Irrelevant attributes
3. State Non-examples
4. Determine its relation to Similar
concepts

Example: estuary
1. Relevant attributes: body of brackish
water, where the river meets the sea,
home to diverse marine life
2. Irrelevant attributes: size, location
(which ocean)
3. Non-examples: lake, stream, reservoir
4. Relation to similar concepts: relation to
delta, bay, wildlife refuge

1. Direct Teaching of Roots and
Affixes
• Latin and Greek roots and affixes are the
building blocks of many multi-syllabic words
• Knowledge of common root and affix patterns
and meanings facilitates word recognition
• This knowledge can improve overall reading
comprehension

Skills
• Students will always need to know
how to use paper dictionaries, but
– Internet-based dictionaries,
– dictionaries on CD-ROM (including
CoBuild),
– hand-held electronic dictionaries

What is CVA?
CVA for short, is the active,
deliberate acquisition of word
meanings from text.
96
Chulalongkorn University Language Institute, 6th International Conference, Bangkok, Thailand November 2006
QuickTime™ and a
TIFF (LZW) decompressor
are needed to see this picture.
CVA Results From
• the meaning gained from the text,
• focus given to the hard word(s)
• connection made between text
meaning and prior knowledge,
• reasoning used to hypothesize a
word’s meaning, and
• assessment of confidence in the
hypothesized meaning
97
Chulalongkorn University Language Institute, 6th International Conference, Bangkok, Thailand November 2006
QuickTime™ and a
TIFF (LZW) decompressor
are needed to see this picture.
Why CVA is important?
• “Skipping” an unknown word in text
does not always result in missed
comprehension, but it often does.
• Skipping unknown words is a missed
opportunity to learn new words.

Excellent 17-18 Year Old Readers
Think Aloud During CVA
• Sets of 5-17 texts, each text using same
hard word
• Consecutively read each text of a set
• Thought aloud when encountering hard
word in each text
• Stated hypothesized meaning (abduction)
• Recorded and transcribed verbal protocol
• Coded verbal protocol

Context is better for helping
readers learn
words they DO NOT know for
things they do know
then for
things and words they DO NOT
know
101

Context is much less helpful
in situations where readers
must learn both a new
concept/thing and the word
that signifies that thing

Focus attention on hard words
Gather data and information
Generate a hypothesized meaning
Test hypothesized meaning

1. Focus attention on hard word
1. Note there is a hard word
2. Got an intuitive (automatic) hunch or
synonym? Test it!
3. Is text considerate: i.e., are there
traditional context clues?
111

2. Gather data and information
1. Reread sentence carefully
2. Try to think of a synonym to fit
3. Determine hard word’s part of speech

might be linked to hard word?
6. Activate prior knowledge—think how
your knowledge relates to hard word
7. Connect prior knowledge & relevant
text meaning (Sternberg’s selective
comparison)

hard word is the subject
2. Visualize the meaning of the text
3. Reasoning—combine text meaning &
prior knowledge (& reaction)
a. Noun reasoning strategies
b. Adjective reasoning strategies
c. Verb reasoning strategies

4. Test hypothesis
1. Replace the hard word with your
hypothesized meaning
2. Confirm / reject your hypothesized
meaning
a. If sentence makes sense,
continue
b. If sentence does not make sense,
start over or . . .

Do Not Model CVA With Words
Whose Meanings are Known!
• The missing aglet made the task
difficult.
• The missing aglet made threading
the shoelace difficult.
• The missing aglet meant the
shoelace had become frayed, so it
was difficult to thread.
