Instruction Practices: Effects of Language and Literacy Instruction on Adult ESOL Literacy Students LESLLA - Tilburg University August 26, 2005 Larry Condelli American Institutes for Research Washington, DC USA
Overview • Research Studies on Effective Instruction for Adult Literacy Students • Literature review on effective instructional interventions • Correlational “What Works” Study (completed) • Experimental Explicit Literacy Impact (ongoing)
Adult ESOL Literacy Students • Limited literacy in any language • Need also to learn English language skills • Have little or no formal schooling (working definition: 6 years or fewer) • May lack “print awareness” • Have no or little phonemic awareness • Need to build “schema” for types of literacy
Purpose of The Research • Identify types of instruction that may be effective in improving the L2 language and literacy skills of low-literate adults • Identify student characteristics related to L2 development • Identify implications for practice and further research
Review of Research in Adult SLA • Focus on identifying hypotheses that can be tested by our research • Focus on studies in adult SLA, second language reading and adult EFL • Research on children included where results also found and accepted for adults • Excluded studies of structural language skills
SLA Topics Addressed by These Studies • Relationship of oral communication skills and literacy • Connecting literacy to real-world tasks in instruction • Use of native language support • Instructional focus on reading and life skills
SLA Research Hypotheses • Oral Language Skills and Literacy – literacy development may be aided when there are oral skills first • Literacy in Context – connection to real-world tasks and materials in instruction may promote literacy development • Native Language Support – Ways literacy in L1 promotes L2 development • Focus on Reading – Direct, systematic or explicit teaching may promote reading and literacy development
Learning Theory • U.S. National Academy of Sciences review suggests 3 keys to effective instruction: • building upon prior knowledge, • engaging in active learning within strong conceptual frameworks, and • promoting transfer and generalization by applying new skills in a variety of contexts
Learning Trinity Engagement Focus Practice
“What Works” Study: Research Design Overview • “Natural” study: conducted in existing classes with no intervention • Two year data collection: 38 classes in 13 school sites in seven states, 495 total students • Students assessed three times: at intake, three months and nine months, regardless of attendance • Assessment battery: included standardized and alternative reading, speaking and writing assessments • Bi-weekly classroom observations: to collect instructional measures
Student Sample • 495 students, 72% female, mean age 40 • Mean 3.1 years education, one third no education • Two-thirds Spanish speaking, 9% Somali, 8% Hmong • Over 30 other languages spoken • Attended mean of 129 hours over 16 weeks • Very little English language or literacy skills
Measuring Instruction • Structured classroom observation guide • Observer kept timed running account • Coded for Instructional emphasis – Proportion of time spent on literacy or language (what was taught) • Ratings of Instructional strategies – Mean score based on ratings of teachers’ methods and student involvement (how it was taught).
Instructional Emphasis Measures • Literacy Development – Main focus on reading and writing development: • Basic literacy skills emphasis (fluency, basic reading skills, grammar, vocabulary). • Reading comprehension emphasis (reading for meaning, prediction strategies). • ESOL Acquisition – Main focus on speaking, listening, fundamentals of English: • Oral communication emphasis (speaking and listening practice).
Instructional Strategy Measures • 20 items measuring teacher use of strategies and student involvement on 4-point scales • Factor analysis to identify scaling • Mean rating across observations on items for four factor-defined scales
Instructional Strategies • Varied Practice and Interaction- • Teachers keep students engaged through a variety of activities, using different modalities and types of literacy • Connection to the “Outside”- • Teachers link what is being learned to life outside the classroom, “real life”
Instructional Strategies • Use of Native Language (Spanish) – • Teachers uses native language to clarify assignments, explain concepts • Students allowed to ask questions in native language
Assessment Approach • Combined standardized and alternative assessments. • Individual administration, test instructions in native language. • Preference for performance-based tests. • Multiple areas assessed: oral communication, writing, reading. • Interview with student.
Assessment Battery – Standardized Tests • Reading - Woodcock Johnson basic skills and comprehension subscales. • Speaking – Basic English Skills Test (BEST) oral interview. • Writing – ALAS writing test and CASAS form completion.
Assessment Battery – Alternative Assessments • Reading Demonstration-Learner rated on reading of self-selected authentic and environmental texts (e.g., food labels, flyers, newspaper advertisements, etc.) • Literacy Practices Interview - Structured interview on reading, writing and speaking habits in everyday life
Analytic Approach: Growth Modeling • Latent growth modeling in an HLM framework • Accommodates complex data: • Random student intra-class variation • Hierarchical, nested, repeated measures • Student attrition • Three parameter model – initial status, linear and quadratic growth over time • Requires model of relevant variables
Findings: Basic Reading Skills Growth in reading basic skills (WJR-BRSC) • Use of “connection to the outside” strategy • Younger students have higher growth • Years of formal education (proxy for native language literacy), but fades over time • Initial English oral proficiency (BEST score)
Effect of the Use of the “Connection to the Outside” Strategy on Growth in Basic Reading Skills
Findings: Reading Comprehension Growth in reading comprehension skills (WJR-RCC) • Use of students’ native language in instruction • Rate of attendance (proportion of hours student attends weekly by hours offered weekly) • Initial basic reading skills (BRSC score) – effect emerges slowly over time (quadratic effect)
Effects of Attendance Rate, Basic Reading Skills and Use of Native Language on Growth in Reading Comprehension
Findings: Oral English Skills Growth in Oral English Skills (BEST) • Use of students’ native language in instruction • Oral Communication instructional emphasis • Varied practice and interaction strategy • Higher rate of attendance • Student age (younger students have higher growth) • Initial basic reading skills (BRSC score)
Effects of Instructional Emphasis on Oral Communication Skills and Practice Strategy on Growth in Oral Communication Skills
Other Analyses • Writing Ability • No significant growth on writing assessments • Reading Demonstration • Weak growth,related to emphasis on reading comprehension and bringing in the outside strategy • Literacy Practices Interview • IRT-developed scales, showed positive change, but not statistically significant
Summary: Instructional Findings and Implications • Bringing the Outside – growth in basic reading skills • Direct connection to students’ lives makes instruction meaningful • Use of Native Language – growth in reading comprehension and oral English skills • Removes comprehension barriers • Safe learning environment • Allows critical thinking skills
Summary: Instructional Findings • Varied Practice and Interaction – growth in oral English skills • Learn patterns from others • Multi-modal learning • Opportunity to practice and test individual language hypotheses
Summary: Student Effects (1) • Formal Education • More educated students had faster growth in basic reading skills development (but faded over time) • English Speaking Skills • Students with high oral English skills had faster growth in basic reading skills development • Basic English Reading Skills • Students with higher basic skills had faster growth in reading comprehension and oral English skills (emerged over time)
Summary: Student Effects (2) • Age • Younger students had faster growth in reading basic skills and English speaking skills • Attendance • Students who attended a higher proportion of scheduled time had faster growth in reading comprehension and English speaking skills
Student Findings: Possible Implications • Formal Education • Possible of L1 transfer • English Speaking Skills • A basis in oral skills in L2 may help L2 reading development • Basic English Reading Skills • Basic reading skills in L2 may promote L2 reading comprehension and oral skills development
Research Question The new study will use random assignment to answer the question: What difference will explicit instruction make in terms of L2 literacy development and language learning for ESOL adults with limited literacy?”
Hypothesis • Explicit literacy instruction creates a conceptual framework of English literacy within which students can engage in active learning and apply their growing skills in a variety of contexts to improve their learning.
Reading Research Support • Reading research for native English speakers who struggle suggests the effectiveness of explicit instruction, within meaningful contexts, of the following components: • Alphabetics (phonological awareness, print awareness, phonics) • Word analysis and spelling • Vocabulary • Fluency • Comprehension
Research on Explicit Literacy • Recent research in learning and literacy development suggests the effectiveness of an explicit instruction for students from diverse backgrounds • Some research on effectiveness for ESOL children and adolescents • No research for adult ESOL • “Learning Trinity” Research
Explicit Literacy Instruction (1) • Adds a focus on literacy development and makes the process of learning a language transparent (skills and strategies) • Exposes the code system of English • Teaches foundational skills (phonological awareness, orthographic awareness, automaticity, fluency, etc.)
Explicit Literacy Instruction (2) • Teaches learning strategies deliberately • Uses multiple modes of learning and teaching (visual, text-based, auditory) • Relies heavily on modeling and guided practice that draw students’ attention to key patterns or strategies and provides immediate constructive feedback
Curriculum • Specially developed curriculum focusing on explicit teaching of language and literacy skills • Appropriate for low-literate adult ESOL • One hour per day over 15 weeks (or 60 hours total) • Replaces part of usual instruction in intervention classes so that both classes have the same amount of instructional hours
Curriculum Features • Will includes skills, strategies and knowledge of different kinds of texts • Will be contextualized within materials that reflect adults students’ interests and needs • Supports various student groupings (homogeneous and heterogeneous; small group; pairs)
Explicit Literacy Impact Study • Evaluates impact of explicit literacy instruction on low literate adult ESOL students • Random assignment design (explicit component vs. “normal” instruction) • Total of 1,800 students in 10 adult ESOL programs (90 in each group per program) • One year data collection, 2006-07
Study Design • Each adult ESOL program to include in study: • Two intervention classes and two “normal” classes, meeting at same times and locations • To offer about 120 hours of instruction over 15 weeks • Intervention class to teach about half time on explicit literacy • Each class to be conducted twice over the year
Teachers in the Study • 4 teachers per ESOL program, randomly assigned (2 per condition) • Initial week long teacher training on curriculum • Site-based ongoing training as needed • Frequent classroom observation to monitor curriculum fidelity
Student Outcome Measures • Pre-test on native language literacy • Post-intervention assessment of English reading, writing, speaking/listening • Student interview on literacy practices • Optional one year follow-up assessment • Assessments conducted individually in students’ native languages
Study Products and Outcomes • Fully developed and evaluated curriculum, with materials, assessment, professional development • Data on effective instruction • Descriptive data on students and programs • Raised visibility of adult ESOL issues around instruction, assessment, professional development
