Characteristics of Learner
Types
Type 1 Learner
Low achievement
Limited or inadequate
exposure to curriculum
Limited literacy history
Responds to
ESL/Bilingual
instruction, but has
more to catch up
Type 2
Low achievement
May or may not have
had limited or
inadequate exposure to
curriculum
May or may not have
had limited literacy
history
Does not respond well
to ESL/Bilingual
Instruction
Typical ESL/Bilingual
approaches either do
not work or require
intense instruction.
Basic Approach to Assessment
(Ortiz, 1997)
Pre-referral
Ensure instruction is appropriate.
Ensure it is implemented appropriately.
Referral
Language Assessment
• Dominance
• Proficiency
Achievement
Attainment
Assessing the learning environment
Typical Assessments
Evaluate programs
and curricula.
• Are they appropriate
for this student?
Examine whether
students have
received appropriate
instruction.
Evince that child has
not learned what was
taught.
Has alternative
instruction been used?
Recommendations for
ELLs
Are ESL/Bilingual
programs in existence?
Are they being
administered
appropriately?
Has the student fared
well in these programs?
Are a variety of
language-learning
methods being used?
Assessing the Student
(Achievement/attainment)
Typical assessments
Determine if alternative
instruction worked
Initiate pre-referral
services
Identify specific sources
of student difficulty
• Oral language first,
then other literacy
skills
• Then specific subject
areas
Recommendations
for ELLs
Examine curriculumbased work samples
in ESL/Bilingual
instruction
Ensure additional
services have been
exhausted
Identify English/L1
sources of difficulty
Specific Tools for Identifying ELLs
Make appropriate comparisons
Examine language use in multiple
contexts for multiple reasons
Examine second language
difficulties in light of language
acquisition process
Are they developing English as
might be expected?
Characteristics of ELL Writing
Difficulties
Poor simultaneous processing
Poor handwriting
Writing verbatim
Inability to coordinate learned skills
into learning outcomes
Promising Practices
Use of Curriculum-Based
Assessment/Measurement (Idol et
al., 1999, Deno, 1989; Shinn, 1989)
Use of Dynamic Assessment
(Jitendra & Kame’enui, 1993;
Jitendra, et al., 1998)
Evaluation Factors: Use of CBA
As compared to other second language
learners
Structure and organization of work
Degree of English/L1 Dominance
Use of subject matter conventions
Knowledge of specific vocabulary/definitions
Accuracy and fluency of content
area/language
Identified consistency in accomplishing tasks
from beginning to end
Dynamic Assessment Process
(Jitendra, et al., 1998)
Determine learning tasks to teach the
student
Develop three alternate forms of the task
Use one form as a pre-test
Administer intervention with form 2
Administer a post test after intervention
(form 3)
Analyze results
Design instruction
Assessment of note taking
Organization
incorporates key facts
systematic (chronological or by topic)
Fluent handwriting
a measure of simultaneous processing
Grouping of ideas
Assessment of Writing
Spelling
Grammar/mechanics
Sentence length
Sentence number
Sentence completeness according to
increasing level of difficulty
Maintenance /consistency of topic
Mathematics Think-Aloud
Strategy
Teacher determines the standards-based mathematics
concept or skill to learn:
Determine Pre-requisite skills
Example: student recognizes part-to-whole relationships,
understands key vocabulary terms (numerator, denominator,
digit, single digit, two-digit) and symbols (=, /)
Conduct Pre-requisite skill assessment (CBM & CBA to verify PrS)
Teacher modeling of strategy (I do it)
Example: representing fractions and their equivalents
Example: “first, I need to [factor the numerator with the
denominator to the lowest number, next, I need to [verify that
both fractions are equal], finally, I need to [start the next
fraction and complete the steps]
Teacher and Student use the Mathematics Prompt Sheet to
teach/learn the strategy (we do it)
Student Guided and Independent Practice (You do it)
Monitor and Evaluate Strategy
Use, Progress, and Student
Check-in
Use of systematic teaching process
Explain what will be done and why
Determine and verify vocabulary needed
Describe strategy steps
Modeling and Prompting of steps
Provide exemplars & visuals
Collect strategy and achievement data during instruction &
practice
Provide student opportunities to verify comprehension of
strategy and process (student check-in)

Applications for ELLs with disabilities
in Group and ESL Settings
Evidence for use of think-alouds with ELLs in ESL settings
Use in conjunction with the CALLA (Chamot, Dale, O’Malley,
& Spanos, 1992)
• For review of Chamot, et al., paper go to
http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.
1.20.9610
A think-aloud procedure was used as a step in preparing for
understanding the problem-solving steps, as a guide during
problem solving and as a reflective (“retrospective”) process
after solving the problem
Students with language and mathematics ability challenges
(“low ability”) had more difficulty and could benefit from
procedures used in our study (cf. Liu, Barrera, & Thurlow,
2009)
Reading Strategies
Student-Developed Post-Reading Graphic
Organizer
Individualized Student Chunking and
Questioning Aloud
Student Chunking and Questioning Aloud
Identify Pre-requisite Skills
Determine Content
Able to read sentences at instructional level
(word attack and word recognition) for gradelevel content.
Identify and determine standards-based content
reading
Determine Instructional Objective
Given content area and standards-based reading
passages at grade level, the student will
complete content comprehension questions of
the reading passages verbally or in writing with
95% accuracy.
Student Chunking and Questioning Aloud
Provide Teacher-Directed Instruction
Teacher divides standards-based content reading into
smaller sections before student begins to read.
Teacher presents and models how to use chunking and
questioning with a sample text. Before reading a “chunk”
the teacher gives a verbal prompt to read for key items of
information in the text.
Teacher leads student through several lessons in using
chunking and questioning
Student reads a section of text and rehearses verbally in
the student’s own words what has just been read. Then
student goes on to next section and repeats until passage
is completed.
Closes book and pretends to be teacher. Asks questions
relating to what they have read. After a while, the teacher
reverses the roles having student answer comprehension
questions (Bondaza, Kelly & Treewater, 1998).
Student Chunking and Questioning
Aloud
Constraints on Chunking
Excessive chunking (chunk’s chunks)
may hinder text comprehension. A
misapplied segmentation strategy
causes slower reading (Keenan, 1984).
Extreme variability in line length may
slow reading by disrupting the rhythm
of eye movements (Keenan, 1984).
Student-Developed Post-Reading
Graphic Organizer
Teacher uses a semi-complete
graphic organizer to introduce and
teach the strategy to the student in
how to construct a self-generated
graphic organizer.
