Goals of This Session
• Analyze the language demands of portions of this unit to
allow ELLs to access its content
•
Model scaffolding strategies and examples for ELLs to give them
support in completing this unit, including:
1) Building background knowledge
2) Developing language and literacy skills in the context of
content instruction (content and language objectives)
3) Using first language knowledge and skills as appropriate
4) Pre-teaching academic and domain-specific vocabulary
5) Instructing ELLs in vocabulary learning strategies
6) Engaging ELLs before, during, and after reading
2
Scaffolding Content Instruction for
ELLs
• Plan content and language objectives
• Analyze academic language of text
• Use targeted ELL scaffolding strategies to
differentiate for instruction at different levels of
English language proficiency
3
CCSS Addressed by the Scaffolded
Ice Age Unit
• CCSS:
– Cite specific textual evidence to support
analysis of science and technical texts
– Distinguish among facts, reasoned judgment
based on research findings, and speculation in
a text
• Grade level: 8

Language Objective
Students will use academic
language of cause and
effect to discuss and write

Defining Features of
Academic Language
• Academic language is language that stands in
contrast to the everyday informal speech that
students use outside the classroom environment
• How it differs from social English
– Discourse level: Discourse complexity – quantity and variety
of oral and written text
– Sentence level: Language forms and conventions – types,
array, and use of language structures
– Word/phrase level: Vocabulary usage – specificity of word or
phrase choice
– Defining features of academic language all operate within a
sociocultural context for language use

What Thawed the Last Ice Age?
By David Biello Wednesday, April 4, 2012
Roughly 20,000 years ago the great ice sheets that buried much of Asia, Europe
and North America stopped their creeping advance. Within a few hundred years sea
levels in some places had risen by as much as 10 meters—more than if the ice sheet
that still covers Greenland were to melt today. This freshwater flood filled the North
Atlantic and also shut down the ocean currents that conveyed warmer water from
equatorial regions northward. The equatorial heat warmed the precincts of Antarctica
in the Southern Hemisphere instead, shrinking the fringing sea ice and changing the
circumpolar winds. As a result—and for reasons that remain unexplained—the waters
of the Southern Ocean may have begun to release carbon dioxide, enough to raise
concentrations in the atmosphere by more than 100 parts per million over millennia—
roughly equivalent to the rise in the last 200 years. That CO2 then warmed the globe,
melting back the continental ice sheets and ushering in the current climate that
enabled humanity to thrive.

What Thawed the Last Ice Age?
Continued
That, at least, is the story told by a new paper published in
Nature on April 5 that reconstructs the end of the last ice age.
Researchers examined sediment cores collected from deep beneath
the sea and from lakes as well as the tiny bubbles of ancient air
trapped inside ice cores taken from Antarctica, Greenland and
elsewhere. (Scientific American is part of Nature Publishing Group.)
The research suggests that—contrary to some prior findings—CO2
led the prior round of global warming rather than vice versa, just as it
continues to do today thanks to rising emissions of CO2 and other
greenhouse gases.

Using First Language Knowledge
and Skills as Appropriate
Aproximadamente hace 20.000 años las grandes capas de
hielo que enterraron gran parte de Asia, Europa y América
del Norte detuvieron su avance progresivo. Desde hace
pocos cientos de años ha aumentado el nivel del mar en
algunos lugares tanto como 10 metros, más que si la capa
de hielo que aún cubre Groenlandia fueron derretir hoy.
Esta inundación de agua dulce llena el Atlántico Norte y
también apaga las corrientes oceánicas que transmiten
agua cálida desde el norte de las regiones ecuatoriales.

Engaging ELLs Before, During, and After Reading
Before Reading
•
Building background knowledge
•
Predicting content of text with scaffolds
•
Pre-teaching vocabulary and idiomatic expressions
During reading
•
Teacher read-aloud of text
•
Student independent reading of text
•
Student translation of text into own words (with partner)
•
Teacher guided discussion (with different questions and scaffolding)
After Reading
•
Focus on both oral language and writing development
•
Use of first language as appropriate
•
Level of scaffolding aligned with students’ levels of English language proficiency
with reductions in scaffolding as students become more proficient in English

Self-Assessment
In what ways can you continue to…
 Build ELLs’ background knowledge?
 Develop language and literacy skills in the context of content
instruction?
 Use first language knowledge and skills appropriately?
 Pre-teach academic and domain-specific vocabulary?
 Instruct ELLs in vocabulary learning strategies?
 Engage ELLs before, during, and after reading?
 Find resources to support all of the above?
