Disproportionality: A Problem

• Disproportionate (both under and over) representation of ELL students in special education has plagued the field since first identified by Dunn in 1968.

• The negative effects of this include:– Inappropriate labeling of students who do not have a

disability– Students who are misidentified are often removed from

general education and lack access to grade level core curriculum

– Some literature (Artiles & Ortiz, 2002; Hosp & Reschly, 2003; Losen & Orfield, 2003) reports that special education programs may be ineffective at increasing student achievement.

Definition of Specific Learning Disability

• 34 CFR 300.7 10) Specific learning disability is defined as follows:(i) General. The term means a disorder in one or more of the basic psychological processes involved in understanding or in using language, spoken or written, that may manifest itself in an imperfect ability to listen, think, speak, read, write, spell, or to do mathematical calculations, including conditions such as perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia.

Page 5: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Definition of Specific Learning Disability

(ii) Disorders not included. The term does not include learning problems that are primarily the result of visual, hearing, or motor disabilities, of mental retardation, of emotional disturbance, or of environmental, cultural, or economic disadvantage.

National Research Center on Learning Disabilities

December 4-5, 2003 * Kansas City, Missouri • Ken Kavale stated:

“If the definition of SLD is not to change, then perhaps closer adherence to what is actually stipulated in the definition might be warranted. One notion clearly articulated in the SLD definition is the presence of "disorder in the basic psychological processes." Although a critical definitional feature of SLD, process deficits have been generally ignored in the identification process (Torgesen, 1979).

Page 7: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

National Research Center on Learning Disabilities

December 4-5, 2003 * Kansas City, Missouri • Ken Kavale stated:

At best, the RTI model can only infer that a process deficit exists and, without direct assessment, there is no way to determine if a student may possess SLD as currently conceptualized (Torgesen, 2002). With modern theories about the importance of processing skills replacing outdated processing views (e.g., perceptual-motor) that were implicit in the SLD concept when first proposed, it becomes critical to re-emphasize process deficits in an operational definition of SLD (e.g., Swanson & Alexander, 1997; Hoskyn & Swanson, 2000).”

Page 8: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

RTI: Changes in LD Determination

• In the newly reauthorized IDEA, eligibility and identification criteria for LD have changed [614(b)(6)(A)-(B)]:

– When determining whether a child has a specific learning disability

• The LEA is not required to consider a severe discrepancy between achievement and intellectual ability.

• The LEA may use a process that determines if a child responds to scientific, research-based intervention as part of the evaluation.

Page 9: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

RTI

• RTI is not required but may be used to determine if a child responds to scientific, research-based interventions as a part of the evaluation procedures [§1414(b)(6)(B)].

Page 10: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

RTI

Experts promote two distinct RTI models (Bradley, Danielson, & Hallahan, 2002; Fuchs, Mock, Morgan & Young, 2003), though in reality most school districts use a combination of the two (NASDSE, 2006). Both models outline tiers or stages of interventions.

Page 11: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

RTI

• Standard Treatment Protocol: the same empirically validated treatment is used for all children with similar problems and achievement is measured against specified benchmarks (NASDE).

Page 12: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

RTI

• Flexible Problem –Solving: problems are defined behaviorally, interventions are planned specifically for the targeted student and are provided over a reasonable period of time, performance is measured in the natural setting, and students’ progress is compared to that of peers (NASDE).

Page 13: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Tier I

• Critical Factor: Is effective instruction in place for all groups of students?

• It cannot be assumed that a comparable amount of English language exposure for an ELL students as compared to a monolingual English-speaking student means we can expect equal language competency.

• Depending on the model of bilingual/ESL program the student has received the amount of language instruction can vary considerably between ELL students.

Page 14: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Tier I Considerations for ELL Students

Do classroom teachers understand the following?• How ELL students acquire and develop their first and second

languages.• How ELL students develop first and second language literacy.• Know cross-cultural differences in communication.• How to adapt instruction to accommodate students with

different levels of English proficiency.• Know how to appropriate assess ELL students in a variety of

ways that allow them to demonstrate their understanding without relying solely on oral or written English that is above the level of their proficiency.

• Know the types of ESL or bilingual programs and services offered to students and can work collaboratively with ESL and bilingual teachers in co-planning or co-teaching lessons.

Page 15: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Literacy Instruction

• There is no evidence that phonemic awareness and phonics instruction in English needs to be delayed until a certain threshold of English oral language proficiency is attained.

• Research (Verhoeven, 1994; Change & Watson, 2000) finds that it does not matter which language literacy is taught in first; but that children must be allowed to become orally proficient in L1.

• Their continuing success in L2 literacy, however, is dependent on their ability to gain literacy in L1 at some point.

Page 16: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Determinant of Academic Success

• The single most important determinant of academic success for ELL students is mastery of academic language.

• The key to content learning is their proficient use and control of academic language.

• ALL ELL students are “AESL” students – Academic English as a Second Language.

How do you Know When ELLs Need Interventions?

• Research shows that it is possible to identify ELLs who are at risk for reading difficulties because of underdeveloped phonological awareness skills and/or difficulty learning sound-symbol correspondence. These students have trouble “cracking the code.”

• Schools tend to overlook or take a “wait and see” attitude with these students believing the difficulties are due to their lack of English proficiency and assume the skills will develop along with their L2.

• When young ELLs experience these difficulties, they need explicit and intensive instruction and/or intervention in phonemic/phonological awareness and phonics (explicit, systematic, and intensive in order to augment students’ abilities).

• ELLs in primary grades, even at the beginning stages of English language development, benefit from phonological awareness instruction and activities either in their L1 or L2 because the skills are transferable.

• Delaying intervention until children gain increased proficiency in English is not advised.

Page 20: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Tier II Intervention Considerations

• Children cannot comprehend what they are reading in a language they cannot speak and understand.

• It appears that readers must be familiar with a minimum of 95% of the vocabulary in the text to comprehend.

• Drrop and Verhoeven (2003) found that extensive vocabulary training is crucial for efficient L2 reading comprehension.

• Research (Kwan & Willows, 1998) also seems to show that for young children, explicit, systematic instruction in L2 sounds/symbols benefits phonemic awareness and it does not appear to be dependent to sound/symbol instruction in L1.

• Students must also have alphabet knowledge.

Page 21: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Tier II Intervention Considerations

• Phonological skills have been shown to accompany dyslexia in many monolingual populations but the effect is smaller in transparent orthographies (when there are explicit links between graphemes and phonemes).

• Research suggests that children with normally developing literacy skills show some phonological awareness in their strong language that they transfer to L2.

• Children’s phonological awareness in L2 can be assessed even when their L2 oral vocabulary is not very well developed.

Page 22: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Tier II Intervention Considerations

• ELL students also need to explicitly learn the rules of the language (grammar).

• This knowledge impacts literacy development by helping with decoding and especially listening comprehension.

Page 23: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Tier II Intervention Considerations

• A child’s native language experience appears to impact their listening abilities in later learned languages.

• Therefore, both L1 and L2 experiences will play a role in a child’s phonological domain.

• In the early stages of reading, phonological intervention was effective for native Spanish-speakers learning to read in English.

• In the early stages of reading, it appears that phonological intervention correlated with better outcomes in reading attainment than an oral proficiency or semantics intervention.

Page 24: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Tier II Intervention Considerations

• Nag-Arulmani, Reddy and Buckley (2003) found that phonological intervention resulted in immediate gains in the use of phonological rules and helped reduce the gap in reading achievement for children whose home language was Spanish.

• These researchers also found that a ten-session program conducted over 3-5 weeks can help contain reading failure amongst children with English as their L2 literacy.

• The interventions must supplement the core programs.

Page 25: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Transferable Skills

• Notions about print, or functional awareness, can be applied to the second language.

• Reading strategies transfer:– Monitoring comprehension– Identifying and repairing comprehension problems– Forming hypothesis– Using genre characteristics– Inferencing– Questioning the author– Relating new information to existing schema

Page 26: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Transferable Skills

• It is imperative to know a student’s literacy skills in L1 in order to know how to help them figure out what skills will transfer to L2.

• Bilingual students report that they use both languages to help them in reading; older students try to translate sentences or think of similar sounding words (cognates) to comprehend an unknown word.

Page 27: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Is There a Role for Standardized Assessments in RTI?

• Yes!

• The definition of Specific Learning Disability continues to include: “disorder in one or more of the basic psychological process involved in understanding in using language, spoken or written…”

Page 28: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

The Red Flags

• The key is children with low levels of certain metacognitive/metalinguistic awareness in their home language need to be observed further. Ask yourself if the reason for this may be that they may be linguistically weak in L1 due to lack of access/modeling.

• “If children have had reasonable exposure and instruction in their L1 and still have not developed certain metacognitive/metalinguistic skills, then we can suspect cognitive/developmental deficits that are likely to affect both L1 and L2 literacy development” (Durgunoglu, 2002, p. 201).

Page 29: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

A New Framework for Equitable Assessment

• Flanagan and Ortiz (2001) classified subtests from most of the published cognitive test batteries based on their degree of cultural loading and linguistic demand and by the CHC ability they measure.

• The classifications are called the Culture-Language Test Classifications (C-LTC).

• Flanagan and Ortiz (2001) concurrently developed the Culture-Language Interpretive Matrix (C-LIM).

Page 30: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Dimensions of Standardized Tests Related to BiasDimensions of Standardized Tests Related to Bias– Tests are culturally loaded:

• the majority of tests used by psychologists were developed and normed in U.S. and inherently reflect native anthropological content as well as the culturally bound conceptualizations of the test developers themselves. Many tests require specific prior knowledge of and experience with mainstream U.S. culture

– Tests require language (communication):

• linguistic factors affect administration, comprehension, responses, and performance on virtually all tests. Even nonverbal tests that reduce oral language requirements continue to rely on effective communication between examiner and examinee in order to measure optimal performance

– Tests vary on both dimensions:

• Tests vary significantly with respect to the degree that they are culturally loaded as well as the degree of language required

Cultural Loading and Linguistic Demand

The student comprehends most conversation and academic discourse but sometimes requires repetition. Meaning is usually clear, but vocabulary and structures are used inappropriately at times.

Page 38: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Academic Language

• Essential components that require explicit instruction:– Vocabulary: all the words that someone

knows, learns, or uses– Syntax: the way words are arranged to form

sentences or phrases– Grammar: the rules according to which the

words of a language change their form and are combined into sentences

Page 39: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

• Academic Language

“Jared is making a comparison of the impacts of chronic sleep deprivation on teens and adults.”

• Comprehensible English

“Jared is studying the similarities and differences in the effects of regular sleep loss on teens and adults.”

Page 40: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Skills within Academic Language

• Vocabulary knowledge (including the multiple meanings of many English words)

• The ability to use increasing word complexity and length over time

• Understanding complex sentence structures and the corresponding syntax of English

• Organization of expository paragraphs• Function of transitional words

Conversational (BICS) vs. Academic Language (CALP)

When a student walks up to a counter to purchase an English-language magazine, she/he uses conversational language skills with the clerk and to make the purchase. On the other hand, in order to read and understand what is in the magazine, as well as discuss the pros and cons of an article, the student needs more advanced language skills. The oral and written language needed to engage in the debate of the article requires advanced and specialized vocabulary, more complex sentence structures, and more complex discourse structures than in conversational language.

One Definition of Culture

“Beliefs, attitudes and values are at the heart of what is meant by culture. They are also at the heart of concern about individual differences within cultural similarities. Beliefs, attitudes and values have developed out of shared and unique past experiences, and they strongly influence (while being influenced by) behavior and perceptions of the world. (Bennett, 1995).”

• How do you define culture?

Page 44: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

• The Iceberg Model of Culture– Above the surface are the

visible cultural aspects– Right below the surface (in

brackets) are aspects that overtly influence interactions and are often sources of cultural misunderstandings

– Far below the surface are the most important, often invisible, aspects of a culture

Page 45: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

Modern Theories of Intelligence

• Modern theories of intelligence such as the Carrol-Horn-Cattell (CHC) are empirically based and identify seven broad areas of abilities.

• These abilities relate to specific academic skills.

• Knowing students’ profiles in these abilities will help to inform instruction.

Page 46: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

CHC Theory

• This theory is a combination of the theories of three researchers:– Cattel– Horn– Carroll

• CHC serves as the theoretical foundation for some of the latest cognitive assessment instruments and is gaining acceptance by assessment specialists (Fiorello & Primerano, 2005).

Italic indicates abilities that were not included in Carroll’s three-stratum model but were included by Carroll in the domains of knowledge and achievement. Bold indicates abilities that are placed under different CHC broad abilities than in Carroll’s model. These changes are based on the Horn-Cattell model and/or recent research (see Flanagan, McGrew & Ortiz, 2000; Flanagan & Ortiz, 2001; McGrew, 1997; McGrew & Flanagan, 1998). *Semantic Processing Speed was previously classified under Gt consistent with Carroll (1993). However, recent data analysis from WJ III now suggests that it may be a narrow Gs ability instead (see Woodcock et al., 2001). See Appendix B for more detailed information regarding both the broad and narrow abilities.

The Culture-Language Interpretive Matrix (C-LIM)

• The C-LIM was designed to answer the question: “Is the measured performance a reflection primarily of actual ability or simply one of cultural and/or linguistic difference?

• The results of an individual’s C-LIM can be interpreted within the following expected pattern of performance for diverse individuals.

Using the Framework

• To use this framework, practitioners will first identify appropriate tests to administer that relate to the initial referral concern based on the CHC constructs.

• Then, assessors can narrow down these choices to the subtests that have the most appropriate level of cultural loading and linguistic demand.

• After the assessment has been completed, the individual subtest scores are then recorded into one of the nine cells on the C-LIM.

• The following slide will give an example of a completed C-LIM.

Patterns on the C-LIM

• Three patterns may emerge on the C-LIM:– The effect of cultural loading only– The effect of linguistic demand only– The overall effect of both culture and language

• When patterns emerge that are not consistent with the expected general pattern of performance for ELL students, then practitioners should look for inter- and intra-cognitive analyses conducted previously and base interpretations on results at that level.

Page 58: Reducing Disproportionate Representation of English Language Learner Students in Special Education: A Comprehensive Framework for Determining Difference

What Do the Patterns Mean?

• When patterns diverge from the expected pattern of performance, then the attenuated scores may not simply be reflecting an individual’s cultural and linguistic differences, but may be reflecting some inherent weaknesses.

• Flanagan and Ortiz (2001) caution that the classifications are not necessarily definitive but are currently be validated by research and that the C-LIM must be used along with other sources of data.

Slightly Different: Includes individuals with high levels of English language proficiency (e.g., advanced BICS/emerging CALP) and high acculturation, but still not entirely comparable to mainstream U.S. English speakers. Examples include individuals who have resided in the U.S. for more than 7 years or who have parents with at least a high school education, and who demonstrate native-like proficiency in English language conversation and solid literacy skills.

Moderately Different: Includes individuals with moderate levels of English language proficiency (e.g., intermediate to advanced BICS) and moderate levels of acculturation. Examples include individuals who have resided in the U.S. for 3-7 years and who have learned English well enough to communicate, but whose parents are limited English speakers with only some formal schooling, and improving but below grade level literacy skills.

Markedly Different: Includes individuals with low to very low levels of English language proficiency (e.g., early BICS) and low or very low levels of acculturation. Examples include individuals who recently arrived in the U.S. or who may have been in the U.S. 3 years or less, with little or no prior formal education, who are just beginning to develop conversational abilities and whose literacy skills are also just emerging.

Implications for Assessment

“Even with bilingual children for whom English is the language of instruction, testing in the first language may be necessary to identify underlying areas of weakness. Although it has been argued that testing in the language of literacy is all that is required to identify literacy difficulties amongst multilingual children, assessments that aim to propose potential causes for those literacy deficits need to consider whether such a limited testing procedure is adequate” (Everatt et al., 2004, p. 150).

How a Student’s Ability Profile can Inform Instruction

• One cause of dyslexia has been hypothesized as a phonological deficit.

• Dyslexia research across non-English and transparent languages (Everatt, et al., 2004; Goswani, 2002) shows that it does not appear that a phonological deficit is the root problem.

• In other words, phonological weaknesses may not cause reading problems in languages with regular or highly transparent scripts (e.g., Spanish and Italian).

• In languages with transparent scripts, reading difficulties might be related to alternative core deficits such as in processing speed, visual/perceptual processes, short term memory, etc.

• One implication of this may be that if a child appears to have a reading-related problem in English and they are a native-Spanish speaker, it may be helpful to begin literacy instruction in the native language and see if the student can “break the code” in a transparent script.

True or False

Teams must wait until ELL students are fully proficient in English in English before considering investigating their academic difficulties. True or false?

ELL students should be fast-tracked for assessment and special education services in order for them not to fall further behind. True or false?

Ell students who are experiencing difficulty must be instructed in English only. True or false?

When no general education services are available to ELL students who are experiencing difficulty, they should be placed into a special education program in order to get academic support. True or false?
