3Project goal
- To develop and test a universally designed
- (Rose Meyer, 2002) strategic digital
reading approach (Dalton Proctor, 2007) to
improving reading achievement of 5th grade
students, including bilingual students and
struggling readers
4Multiple perspectives required
5Universal design for learning (Rose Meyer, 2002)
- Design for the broadest range of learners from
the beginning avoid retrofitting - Provide multiple means of
- Representation
- Expression
- Engagement
6Assumptions
- Shift to universal design perspective
- Attention to diversity and individual difference
benefits individual and society - New literacies, while more complex, are more
flexible and inclusive - potential to level the playing field for those
who have not fared well with print literacy

10How does ICON support diverse learners in
relation to
- Representation?
- Expression?
- Engagement?
- What is unique for ELLs?
- What features/supports are essential for some
good for many/all?

15Coaches
Level 1 coaches provide text-specific models and
think alouds. As skill increases, students
select strategies and coaches provide generic
think-alouds.

20All 3 years/studies Feasibility, appeal
usability
- Teachers and students view ICON as a helpful
reading tool, easy to use, engaging - Technical support required bandwidth issue
- Variation in teacher enactment of ICON suggests
need for additional study - English proficiency levels influence ways in
which students use ICON and extent to which
additional support is needed - Peer collaboration one means of support
- Increased sensitivity to learner (needs, use of
system, performance) is likely to benefit all
21Y1 Study of Semantic Depth
- 35 students, 24 bilinguals (Spanish and other
low-incidence languages), 11 English monolinguals - Oral language skills (WJ picture vocablistening
comprehension) - Reading skills (WJ passage comp MCAS ELA score)
- Average semantic depth score for 8 target words
(Anxiously, Bitter, Dense, Grasp, Ignore,
Menacing, Powerless, Relieved)
22Yr. 1 study of semantic depth(Proctor, Uccelli,
Dalton, Snow, in press)
- Effective teaching and learning activities
targeted - for further analysis Caption-It
-
23Semantic depth was a significant predictor of
reading performance, mediated by interaction with
English oral language proficiency
No effect for language status (bilingual vs.
monolingual)
24What did we learn from Y1 vocabulary study?
- Caption It Encouraging but preliminary As both
an activity and an assessment, it appeared to
reduce the monolingual/bilingual gap in students
performance, though oral language was heavily
implicated - Semantic Depth Promising but far from final
- Semantic depth showed a positive association with
reading comprehension, beyond the contribution of
decoding and oral language skills - Semantic depth seems to play a more prominent
role as oral language skills improve - Semantic depth refers to a cluster of skills
associations among these and with other
dimensions of vocabulary depth need to be
explored.
25Year 2 study Strategies vs. vocabulary vs. combo
- Very hard to find research that compares effects
of vocabulary versus comprehension instruction - Likely because the two are so strongly
intertwined -
- Given that vocabulary is a primary focus of
instruction for ELL students, we found this
question intriguing, and asked 2 basic questions - Does assignment to condition (Vocabulary-only,
Strategy-only, Combo) affect students
performance on standardized and
researcher-developed measures of vocabulary and
comprehension? - Do the effects vary by language status
(monolingual, Spanish-English bilingual, other
bilingual)?
26Our hypotheses
- For standardized and researcher-developed
- vocabulary
- Combo gt Vocabulary gt Strategy
- For standardized and researcher-developed
- comprehension
- Combo gt Strategy gt Vocabulary
27Y2 study of vocab vs strategies What matters
and for whom?(Dalton, Proctor, Uccelli, Mo,
Snow, in preparation)
- 106 students, 21 Spanish-English bilinguals, 17
other-English bilinguals, 68 monolinguals in 6
classrooms, 3 districts - Random assignment to condition (vocabulary,
strategy, combination) - 14-week intervention
- Pre-post standardized testing, embedded
vocabulary and comprehension quizzes
28Y2 effect size overview
29What did we learn from Y2 study of vocabulary vs.
reading strategies vs. combined?
- Overall, hypotheses held, and combination version
showed strongest results across standardized and
researcher measures - Did the small sample size mask learner by
treatment interactions? - Theoretically, an interaction between student
characteristics (reader type and/or language
status) would make sense - Sample size may be too small
- Student controls access to support and may not be
making good decisions about when and how to use
support - Thresholds of language proficiency
30Year 3 study Combo vs control
- Having established general effectiveness, time to
move to - a comparison between treatment and control using
optimal - version of ICON
- Quasi-experimental study
- 12 classrooms, classrooms assigned randomly to
treatment or control condition, n 227 (108
control, 119 intervention 10.5 other
bilinguals, 48.5 Spanish-English bilinguals, 41
English monolinguals) - For intervention group, 2 x 50 minutes per week,
for 16 weeks - For control group, across the three districts,
standard literacy curriculum included reading
strategies focus, but limited vocabulary
instruction - Initial training of teachers and students by
research team, gradual release of ICON prototype
teaching responsibility - Analyses conducted at student level,
randomization at teacher level
31Y3 measures
- Gates-MacGinitie reading vocabulary and
comprehension subtests pre- and post-intervention - Aprenda reading vocabulary - pre
- Researcher-designed breadth of vocabulary
(targeted words) post-intervention - 20-item multiple choice assessment
- Reseacher-designed depth of vocabulary,
- post-intervention
- 5-item definition, drawing, captioning
assessment
32Y3 results
- General results
- No effect of condition on standardized measures
significant voc and comp gain for both groups - Strong effect of condition on researcher
developed measures

36Conclusions and next steps
- Continue to analyze Year 3 data
- Worklog responses, multimodal retellings, student
feature use, teacher use of feedback support. - For whom does this intervention work best?
- Goal 3 effects for Spanish-English bilinguals
and struggling readers are intriguing - Goal 2 Work for transfer. Design for increased
sensitivity to learner characteristics,
especially language proficiency. - Distal effects on standardized measures
