The Next Generation Science Standards (NGSS)shift what it means to teach and learn science. One
significant change emerges from the central role of
discourse. As the practices are language-intensive and the
performance expectations explain what a student should
be able to do in science, every student must learn the lan-
guage of science while at the same time learning core ideas
and crosscutting concepts. The performance expectations,
like all of the NGSS, are intended for all students—in-
cluding English language learners (ELLs). This article
explores the ELL Earth science vignette in the NGSS case studies in second grade by (1) focusing on the ways
that teaching and learning science can be approached with
ELLs by supporting and fostering collaborative language
of science in the diverse classroom and (2) illustrating an
authentic application of three-dimensional learning with a
unit that is aligned to the NGSS. This article alerts teach-
ers to the rich resources that are the case studies in Ap-
pendix D (NGSS Lead States 2013), which may be used
to reflect on practice and support shifts toward three-di-
mensional learning.
Each team of students had dug small soil pits in the urban marsh, the coniferous hill, and the school yard field. For each site, they recorded data about soil composition and infiltra-tion, and designed, to scale, diagrams of soil profiles. Now,
with their teams, they were making claims, looking for evi-dence to support their claims, and recording their reasoning on large white boards.
One group—Kaleem, Moustafa, and Victor—was work-ing closely together. Kaleem consulted his partners who were sifting through one of the soil samples, looking for clues. “Feel this! Feel this, you guys; this is so sandy. Here feel.” He handed one of the plates of soil to Victor. “Don’t you think that is sandy?” He looked at the open page in his science notebook; the class had previously tested and written about the compositions of the different soils.
Victor and Moustafa were focused on something they had discovered in one of the soils, pine needles. Moustafa, a recent newcomer from Gambia, said, “This is this thing, this is…” He held up the pine needles. Kaleem supplied the word, “pine needle?” Then Kaleem added dramatically, “Oh! Coniferous hill.”
The boys tramped over to the wall-sized diagrams that the class had made of the soil profiles for each location. These diagrams served as models to help the students think about and explain differences in soil. Only one of the soil profiles had pine needles in the model, and that was the coniferous hill. Victor looked at his notes on coniferous hill and stated, “There are small roots three [inches] down. And pine needles one [inch] down.” Victor used the teams’ field notes to rein-force his thinking about the type of soil.
Moustafa pointed to the colors on another adjacent mod-el, “And the soil was dark, dark, dark black, and it looks like black.” Kaleem responded to Moustafa, “What do you mean?” Moustafa said, pointing to the soil and running his finger along the soil profile for the urban marsh, “Here, urban marsh, it is wet soil, dark, dark black.” He looked for the label ‘organic’ on the diagram, found it and without reading, added, “Organic soil.” Mustafa’s specialization was the urban marsh; his group members knew this and nod-ded, appreciatively. They were well on their way to solving the mystery.
The VignetteAcquiring Language and Integrating New Science Knowledge Through the Practice of Developing and Using ModelsThe vignette introduces a second-grade teacher and her
students in an inclusion classroom at a Title I majority/
minority school. The class is exploring soil and how and
why soil looks different in different locations. The driv-
ing question for the science unit is: Is all soil the same ev-
erywhere? Students have already developed a conceptual
map about soil and interviewed their parents about how
soil is different in different countries. After the conversa-Students choose locations to sample soils.

tions with families provided enough evidence to support
the claim that soil is different in different countries, the
students wanted to find evidence of soil differences in the
community. Throughout the unit, the teacher, Ms. Lo-
zano, provided scaffolding and support for students to de-
velop models, use scientific language, and collaborate with
one another in teams.
Developing Claims Based on EvidenceThe class examined an aerial map and a topographical
map to choose three locations that may have different soil.
Some of the students were interested in the possibility of
soil being different colors, and they wondered what the
soil would be like under a coniferous tree on a hill. They
wanted to compare this soil with soil in the lowest loca-
tion on the map, an urban marsh under a freeway near the
government-supported housing where most of the stu-
dents live.
Ms. Lozano dug three pits in each location and asked
the students in groups of three and four to record ob-
servations on their clipboards (for outdoor exploration
safety tips, see NSTA Connection). The students col-
lected data about the layers of soil they found: Each
layer’s color, how deep each layer was, and the number
of roots, insects, and other organisms they encountered
in the pit. The students also observed infiltration of the
soil. They were amazed to find water at the bottom of the
pit in the school yard field and lots of insects and worms.
The urban marsh smelled bad and had trash and sand
in the soil. The students who live near the urban marsh
were dismayed to find so much trash in all layers of the
urban marsh and that the coniferous hill had no plants
growing under the tree; only a few worms.
Back in the classroom with containers of soil from the sites,
the students tried to decide together if each soil was com-
posed of sand, silt, or clay. They were separated into expert
groups to develop soil profile models using the evidence they
collected. They found patterns in the models that explained
how soil was the same or different in their neighborhood. For
example, although all of the models showed that organisms
live in the soil, the students observed that each soil supported
different organisms. They also noticed that the urban marsh
had really wet soil and the coniferous hill had dry soil. The
soil on the school yard field had water eight inches down.
Two of the models—the school yard field and the coniferous
hill—were made up of layers of soil with different colors.
As students engaged in the science and engineering
practice of developing models, they used models to rep-
resent what they discovered and to explore the patterns
of the phenomenon at hand. In this case, the models were
used to explore the driving question, “Is the soil in our
neighborhood the same?” The model provided language
support for all students by having students use visuals to
display data, express their developing understanding, and
participate in student-to-student sense-making. For ex-
ample, many of the students gestured toward the model
Focusing on the ELL NGSS Case StudyThis excerpt is from the case study on English language learners, one of the seven case studies in Appendix D: All Standards, All Students of the Next Generation Science Standards (NGSS) (see Internet Resource). The case studies center on the four federally defined accountability groups—economically disadvantaged students, students from major racial and ethnic groups, students with disabilities, and limited English proficient students (the federal term)—and three additional groups: girls, students in alternative education, and gifted and talented students. The case studies demonstrate successful implementation of the NGSS in real classrooms with diverse student groups across science disciplines and grade levels. The case studies can inform teaching, collaboration, study groups, and professional development.
This article focuses on the ELL case study to provide ideas for teaching science to ELLs within a diverse classroom context. The case study describes a six-week unit in a second-grade classroom taught
by the lead author while serving on the NGSS writing team. Teachers will find strategies to engage and support ELLs in three-dimensional science learning. Our hope is that the vignette of classroom teaching becomes a catalyst for conversation and innovation among teachers, and empowers teachers to reflect more powerfully and make better strategic decisions in the science classroom. We intend the case study as the beginning to a longer ongoing discussion about making science more accessible for ELLs and other underserved students.
The ELL case study, like the other case studies, has three main sections: (1) the vignette illustrating what teachers can do to successfully engage ELLs in three-dimensional learning of the NGSS, (2) a brief summary of the research literature on effective classroom strategies for ELLs, and (3) the context for the ELL population with attention to demographics, science achievement, and education policy.

as they spoke, using the pictures and the labels to support
their words. Students were also supported in making com-
parisons among the models because of the distributed ex-
pertise in location and soil type.
Ms. Lozano designed the next lesson to oblige her students
to construct explanations using their soil profile models. She
gave each of the student teams (composed of students with
different levels of expertise) a question to answer: Where did
the soil sample come from? Each team received three plates
of soil: one from the coniferous hill, the school yard field, and
the urban marsh. Ms. Lozano challenged the teams to work
together and develop claims about the specific soil locations.
She also reminded students to wash their hands after
working with the soil. The students found evidence
from the model and their science notes to support
their claims. For example, the team of Victor, Kaleem, and
Moustafa provided the following evidence to support their
claim: “This soil came from the coniferous hill because it
shows there are pine needles at that place and there are pine
needles in the dirt.”
Using Models to Design and Share Solutions
Finally, students were given a culminating modeling task
that, along with the explanations written in notebooks,
served as an informal assessment opportunity for the stu-
dents. This final task would give Ms. Lozano an idea as to
what students were individually understanding about the
interactions between water and land. Ms. Lozano asked
her students to individually draw an engineering solution
that stops the wind and rain from changing the soil. Earlier
in the week, when the students were coming back from the
urban marsh, the students noticed that wind blew trash
into the soil. They also figured out that the urban marsh
soil was so sandy because the rain washed sand into the
soil from the road. In Wisconsin, the roads are covered
with sand in the winter to prevent traffic accidents.
The students first met in threes to discuss the problem.
Then they individually designed creative solutions to stop
the wind and rain from changing the soil and shared their
ideas in their teams. They were able to collaboratively
discuss the solutions because the unit had focused on the
same phenomenon with repeated hands-on, culturally
relevant, and socially meaningful experiences. Kaleem
thought that a great solution would be to place a sign near
the urban marsh that asks people to not throw trash in the
ground or spread sand on the street. Zytasia wanted to dig
pits surrounding the urban marsh to catch the trash and
sand before it flows into the marsh. Moustafa was sure
that building a big house on top of the marsh will keep it
from collecting trash. Pao drew a row of identical women
in triangle-shaped skirts holding umbrellas in a long line
over the marsh.

NGSS and Connections to the Common Core State Standards (CCSS) for English Language Arts and MathematicsThe three dimensions of the NGSS work together and are
indicated with parentheses when they appear in the vi-
gnette on the web (see Internet Resource). The classroom
instruction builds understanding toward multiple perfor-
mance expectations that are grouped, or “bundled,” in the
unit. The performance expectations met in the vignette
are from physical science, life science, and engineering, in
addition to Earth science.
Online, we share a chart showing performance expecta-
tions from several standards that are addressed in the case
study (see NSTA Connection). When teachers are plan-
ning their instruction, they must bundle the standards
from multiple science disciplines in order to best explain
the phenomenon, and to exemplify how science is now ap-
proached in college and career. The case study concludes
with an architecture summarizing the bundled perfor-
mance expectations from multiple science disciplines. The
architecture features all of the performance expectations
met during the specific vignette. Furthermore, this archi-
tecture brings in the connections from the vignette to the
CCSS for English language arts and mathematics in the
same design as in the NGSS. Teachers who are interested
in teaching integrated lessons across subject areas will find
this feature helpful. In the Earth science unit of the ELL
case study, the vignette shows how integration can not
only be accomplished, but reinforces both content learn-
ing and language acquisition across the NGSS and CCSS
through repeated experiences.
Effective Strategies from Research LiteratureEach case study describes effective strategies for imple-
mentation of the NGSS in the classroom, at school, at
home, and in the community. The NGSS increases expec-
tations that ELLs engage in the language-intensive prac-
tices, and teachers need to support ELLs in collaborative
sense-making about big ideas in science (Lee, Quinn, and

Valdés 2013). The research literature for ELLs includes
five domains of strategies that teachers can employ to en-
able ELLs to access science (Fathman and Crowther 2006;
Lee and Buxton 2013; Rosebery and Warren 2008):
• Literacy strategies support student understanding of
the structure of texts, graphs, and scientific genres of
writing.
• Language support strategies include the English for
speakers of other languages (ESOL) strategies to
develop language including structures and vocabulary
needed for the science classroom.
• Discourse strategies include the tools that involve
students in authentic talk and sense-making.
• Home language support and cultural connections
involve the teacher’s effort to value and build on the
intellectual resources that students bring from home
and community.
Each of these strategies is explained more fully in the
case study, and then exemplified in the vignette.
ContextEach case study in NGSS Appendix D provides the con-
text of a specific student group in terms of demographics,
science achievement, and educational policy. The NGSS
were released at a time when ELLs are the fastest grow-
ing population of students and represent 21% of the na-
tion’s students (NCES 2014). While the ELL population
is rising, science achievement remains below proficient ac-
cording to NAEP where only 3% of eighth graders scored
proficient in science (NCES 2013). This is a trend that has
remained relatively stable since 1996 despite increased ac-
commodations for testing. Finally, the policy that address-
es ELLs in the nation’s schools varies by state in terms of
accountability, assessment, and identification, thus mak-
ing it difficult to compare information about ELLs across
states.
Conclusion The ELL case study in Appendix D is unique as part
of the standards documents because it demonstrates a
commitment to accessibility for all students in a teacher
friendly and focused teaching example. It underscores the
NGSS commitment to make sure that STEM becomes a
viable option for all students.
Teachers are doing amazing things every day with stu-
dents in science. This case study, rather than be the final
word on the topic, should provoke teachers to realize that
the everyday teaching they do with ELLs would be com-
pelling for others to read and try out with their own stu-
dents. Notwithstanding, this case study gives insight into
how modeling, as language intensive practice, is also a lan-guage scaffold and an impetus for meaning-making among
ELLs and students who speak English in the home.
The ELL case study describes a real classroom ex-
ample of three-dimensional learning as envisioned by the
NGSS—science and engineering practices, crosscutting
concepts, and disciplinary core ideas—that are connected
to the CCSS for English language arts and mathematics.
The teacher uses effective classroom strategies to provide
access to more rigorous science learning for ELLs. The ef-
fective teaching of science engages ELLs in science and
engineering practices and rich language use through col-
laborative sense-making with other classmates. Equitable
learning opportunities for ELLs are achieved as the NGSS ensure access for all students. ■
