7Importance of Vocabulary
What we know from research
-
- Children enter school with meaningful differences
in vocabulary knowledge as a result of
differences in experiences and exposure to
literacy and language activities. (Hart
Risley, 1995) -
- The vocabulary gap grows larger in the early
grades. Children who enter with limited
vocabulary knowledge grow much more discrepant
over time from their peers who have rich
vocabulary knowledge. (Biemiller Slonim,
2001)

10Project VITAL
- Implications
- Many students begin school at risk for language
and comprehension difficulties. Instruction and
intervention focused on code based skills will
not be sufficient to meet these students needs. - Instruction and intervention in meaning based
skills (e.g., language, vocabulary, listening
comprehension) should start at the beginning of
schooling. - This instruction should often be separate from
code based instruction, especially in the early
grades. (i.e., within oral language activities)
11Vocabulary Instruction
- Program of Research Questions
- How do we best provide direct vocabulary
instruction? - Is vocabulary knowledge gained through direct
instruction maintained over time? - Does systematic review help students maintain
vocabulary knowledge - Does direct vocabulary instruction have benefits
beyond learning target words? - Is vocabulary instruction equally effective for
all students? - Can Tier 2 vocabulary intervention increase the
word learning of students at risk of language and
learning difficulties?
12Direct Vocabulary Instruction The Challenge
- It is impossible to teach directly all that words
that students need to know.
How can we best leverage scarce instructional
time?
13Vocabulary Instruction
-
- Given limited instructional time, do we
- Teach more word meanings but spend less time on
each word? - or
- Teach fewer word meanings but spend more time on
each word?
14Vocabulary Instruction
- Two Approaches to Vocabulary Instruction
-
- Embedded Instruction
- Simple explanation within the context of the
story. (e.g., Biemiller Boote, 2006 Penno
et al., 2002) - Time efficient allows for introduction of many
words (breadth). - Few exposures to target words, limited to context
of the story - Extended Instruction
- Robust approach that offers rich information
about words and their uses. (e.g., Beck,
McKeown, Kucan, 2002 Coyne, Simmons,
Kameenui, Stoolmiller, 2004) - Time intensive limits instruction to fewer
words (depth). - Many encounters with words in varied contexts
beyond the story.
15Project VITAL
- Research Question
- What are the effects of Extended Instruction vs.
Embedded Instruction vs. Incidental Exposure?
16Project VITAL
- Methodology
- Participants included kindergarten students from
schools with large at-risk populations. - Within subjects design with different sets of
target words taught with different instructional
approaches. Words were counterbalanced across
groups. - All participants listened to multiple readings of
storybooks in small groups over two weeks.
17Type of Instruction
- Embedded Instruction
- Simple explanation of target words provided
within the context of the story. Provides both
definitional and contextual information. - (Biemiller Boote, 2006 Stahl Fairbanks,
1986 Penno et al., 2002)
18These bricks will make a fine sturdy house,
said the third little pig.
Sturdy means strong. Now Ill say the sentence
again with word that mean sturdy. These bricks
will make a fine strong house. In the picture
the little pig says that the bricks (point to the
bricks) will make a sturdy, or strong, house.
Everyone say sturdy.
19Type of Instruction
- Extended Instruction
- Simple explanation of target words provided
within the context of the story. Extended
activities after story reading. - Extended vocabulary instruction is characterized
by explicit, conspicuous teaching that includes
using both contextual and definitional
information, giving multiple exposures of target
words in varied contexts, and encouraging deep
processing. - (Beck, McKeown, Kucan, 2002 Stahl, 1986
Stahl Fairbanks, 1986)
20Beck, I.L., McKeown, M.G., Kucan, L. (2002).

instruction. New York Guilford.
21Type of Instruction
Lets play a game about our magic word
drenched. Ill show you some pictures. If you
think the picture shows something that looks
drenched, or really wet, put your thumb up like
this and whisper, That looks drenched. If
the picture doesnt show something that looks
drenched, dont say anything.
22Type of Instruction
(Show picture) Do these children look drenched?
If you held up your thumb like this, youre
right! The children in this picture look
drenched, or really wet. The children laughed
as they got drenched playing in the water
fountain.
23Type of Instruction
Picture 1 (Man in the rain) The man in this
picture is drenched, or really wet. This
picture reminds me of a time when I was outside
at a picnic. The skies got very dark and it
started to rain. I ran to get inside the nearest
building but it was too late. I got drenched from
the rain. I felt cold and wet until I changed my
clothes. (remove picture) Tell me about a time
when you were drenched from the rain.
24Type of Instruction
- Lets play a word game. Ill tell you about some
things. If you think it is strong, say Thats
sturdy! If you think it is not very strong, say
Uh oh, thats not very sturdy! - Examples
- A big jet airplane in the sky.
- A little paper airplane on a windy day.
- A tall tower made of cards.
- This school.
- A big huge rock.
- A snowman on a hot sunny day.
25Type of Instruction
Do you think a cauldron is sturdy? Why? Would you
be approaching a cauldron that was full of
snakes? Why? If a storm was approaching, would
you go into a sturdy house ? Why? Would you put a
cauldron on a chair that wasnt sturdy? Why? What
would you do if a dog was approaching your
cauldron full of food? Why?
26Type of Instruction
- Incidental Exposure
- Students hear target words in the context of the
story. No additional instruction is provided.

30Effects of Instruction
- Two types of vocabulary knowledge
- Breadth of knowledge
- How many word meanings a student knows
- Depth of knowledge
- How well a student knows an individual word
meaning
31Vocabulary Instruction
- What does it mean to know a word?
- No knowledge
- General sense
- Narrow context-bound knowledge
- Having knowledge of a word but not able to recall
it readily enough to use it in appropriate
situations - Rich, decontextualized knowledge of a words
meaning, its relationship to other words, and its
extension to metaphorical uses (Beck, McKeown,
Kucan, 2002)
Knowing a vocabulary word is not an
all-or-nothing proposition.
32Effects of Instruction
33Vocabulary Instruction
-
- Given limited instructional time, do we
- Teach more word meanings but spend less time on
each word? - or
- Teach fewer word meanings but spend more time on
each word?
34Tri-level Approach
- Incidental Exposure
- Read storybooks to children that contain varied
and complex vocabulary. - Much of childrens vocabulary development occurs
as the result of incidental and cumulative
exposure. - Embedded Instruction
- Provide embedded instruction on a subset of
words from the storybook. - Target words that students are unlikely to know
and that they will continue to encounter in
school and in texts. - Extended Instruction
- Provide extended instruction on a subset of
words from the storybook. - Target words that are essential for understanding
important ideas and concepts in the story and
that students need to make immediate use of.
35Vocabulary Instruction
- Question
- Is vocabulary knowledge gained through direct
instruction maintained over time?
36Vocabulary Instruction
- Research Evidence
- In our research, weve found that vocabulary
knowledge is durable, but higher and more
complete levels of word knowledge may be more
susceptible to deterioration over time
37Vocabulary Instruction
38Vocabulary Instruction
39Vocabulary Instruction
- Question
- Does systematic review help students maintain
vocabulary knowledge - Research Evidence
- Review Conditions Target words were assigned to
1 of 3 types of review that varied in intensity
no review, embedded review, or semantically-relate
d review.
40Vocabulary Instruction
- Implications
- Findings suggest that systematic review or at
least continued encounters of target words in
supportive contexts are needed to reinforce and
maintain strong and complete lexical
representations - Review provides a large educational benefit for a
modest amount of instructional time
41Vocabulary Instruction
- Question
- Do the effects of vocabulary instruction and
intervention transfer to other areas of language
and literacy? - A much stronger case could be made for the worth
of vocabulary instruction if there was evidence
to suggest that there were benefits beyond just
learning the meanings of words targeted for
instruction. -
- Possible impacts
- Listening/reading comprehension
- Generalized vocabulary knowledge
42Vocabulary Instruction
- Possible mechanisms to explain transfer effects
- Listening/reading comprehension
- Instrumentalist hypothesis (Anderson Freebody,
1981 Stahl, 1991). - Teaching the meanings of words that appear in a
story or passage should improve students
comprehension of that passage. - Generalized vocabulary knowledge
- Metalinguistic hypothesis (Nagy, 2007).
- Rich vocabulary instruction may increase
students ability to reflect on and manipulate
language in an active and considerate manner. - Connectionist models of word learning (Landauer
Dumais, 1997) - Learning new word meanings helps refine and
consolidate the lexical constraints of other
partially known words that are semantically
associated with the newly learned words.

44Vocabulary Instruction
- Participants
- Participants included 123 students from three
elementary schools serving diverse groups of
students from at-risk populations. 80 students
were in the treatment group and 43 were in the
no-treatment control group. - In two schools, intact classes were assigned to
either treatment (n 3) or control (n 2) and
classroom teachers delivered the intervention to
the whole class. - In the third school, students from three
classrooms were randomly assigned to treatment (n
23) or control (n 21) and the intervention
was delivered by two graduate students in small
groups of 3-5 students outside of the classroom.
45Vocabulary Instruction
- Transfer Measures
- Peabody Picture Vocabulary Test PPVT-III Norm
referenced measure of generalized receptive
vocabulary. - Listening Comprehension Factual inferential
questions about a story that contained target
words (18 target/395 total words). Adapted from
the SNAP.
46Vocabulary Instruction
Research Evidence
47Vocabulary Instruction
- Implications
- Findings suggest that extended vocabulary
instruction implemented with kindergarten
students can result in statistically and
educationally significant differences on both
proximal measures of target word knowledge and
transfer measures of generalized language and
literacy.

- Is vocabulary instruction equally effective for
all students? - Initial level of receptive vocabulary knowledge

- Implications
- Response to the vocabulary instruction was
moderated by overall receptive vocabulary
knowledge assessed at pretest - ELLs, on average, did not respond as strongly to
the vocabulary intervention as EOLs - After controlling for initial English receptive
vocabulary knowledge, language status was not
related to outcomes
64Project IVIIntensifying Vocabulary Intervention
Funded byInstitute of Education SciencesU.S.
Department of Education
- Purpose
- Draw on validated principles of instructional
design and delivery to intensify vocabulary
instruction/ intervention to optimize its
effectiveness with kindergarten students most at
risk of learning disabilities.
65Vocabulary Instruction
- Question
- Can Tier 2 vocabulary intervention increase the
word learning of students at risk of language and
learning difficulties? - Research Evidence
- All students received whole class Tier 1
vocabulary instruction - Students with lower levels of vocabulary
knowledge (PPVT lt 92) received additional Tier 2
intervention on half the target vocabulary words
66Vocabulary Instruction
67Vocabulary Instruction
68Vocabulary Instruction
69Vocabulary Instruction
- Research Evidence
- Students at risk for language and learning
difficulties learned words that receive both Tier
1 Tier 2 instruction to a greater extent than
words that received only Tier 1 instruction. - The word learning of students at risk for
language and learning difficulties who receive
both Tier 1 Tier 2 instruction was approached
the word learning of their peers who were not at
risk who received only Tier 1 instruction.
70Vocabulary Instruction
- Implications
- It is likely that vocabulary instruction will be
more beneficial for students with higher levels
of vocabulary knowledge - Students at risk of language and learning
difficulties will likely require additional
instruction at higher levels of intensity to make
gains similar to their peers who are not at risk. - The vocabulary gap will be extremely difficult to
close
71Vocabulary Instruction
- What we know
- Students can learn the meanings of sophisticated
vocabulary through direct instruction - Greater investment in instructional time
intensity leads to increased word learning
(breadth depth) - e.g., extended instruction, systematic review,
Tier 2 instruction for students at risk - What we may know
- In addition to increases in target word learning,
direct vocabulary instruction may lead to
generalized gains in language and literacy skills
and knowledge.
72Vocabulary Instruction
- What were still working on
- What words should we teach?
- How do we best assess vocabulary knowledge?
- How do we best support vocabulary development
within a multi-tiered model? - How do we combine direct vocabulary instruction
with instruction in other areas of meaning based
skills? (e.g., listening comprehension,
morphology, syntax, figurative language, etc.) - How do we best support vocabulary development for
the entire range of learners? (e.g., ELLs, SLI,
Tier 3 etc.,)
73Vocabulary Instruction
- What words should we teach?
- Tier II words (Beck McKeown)
- Content area vocabulary (Hiebert)
- Developmental sequence of root words (Biemiller)
74Vocabulary Instruction
- How do we assess vocabulary knowledge?
- Measuring the impact of vocabulary instruction
and intervention - Target word learning
- Transfer to other areas of language and literacy
75Vocabulary Instruction
- How do we assess target word knowledge?
- Vocabulary knowledge and development is complex
and multifaceted. However, existing approaches
for measuring vocabulary are blunt and single
dimensional.

80Vocabulary Instruction
It may be that vocabulary instruction does not
promote far transfer-that is, it is conceptually
incapable of moving beyond the texts to which it
is tied. Hence it shows up in local but not
global indicators ... An alternative, is that
our measures are inadequate to the challenge of
documenting the relationship between word
learning and global measures of comprehension.
That is, it might be that our instruction is
improving vocabulary learning, which might lead
to improvements in general comprehension, but the
instruments we use are so insensitive that they
prevent us from documenting the
relationship. Pearson, P. D., Hiebert E. H.,

How do we support vocabulary development within a
multi-tiered model?
An effective, comprehensive, reading program
includes reading assessments to accomplish four
purposes
Screening - Assessments that are administered to
determine which children are at risk for reading
difficulty and who will need additional
intervention. Diagnosis - Assessments that help
teachers plan instruction by providing in-depth
information about students skills and
instructional needs. Progress Monitoring -
Assessments that determine if students are making
adequate progress or need more intervention to
achieve grade level reading outcomes. Outcome -
Assessments that provide a bottom-line evaluation
of the effectiveness of the reading program.
