Mathes, 2009). Christensen and Bowey (2005) demonstrated that first grade students
who were given explicit instruction to decode phoneme–grapheme patterns and words
developed from these patterns made stronger gains on spelling measures of unique words
with vowel combinations than those who were not directly taught. Gains were also noted
in phonemic awareness, alphabetic understanding, decoding and spelling when compared
with other similar students receiving alternate onset–rhyme or implicit phonics
instruction. Nguyen (2012) suggested the use of sheltered instruction, also referred to as
Specially Designed Academic Instruction in English (SDAIE) is another approach that
emphasized the development of grade-level academic competencies (Echevarria &
Graves, 2007).
Based on the strategies mentioned above, both Cruz de Quiros, Lara-Alecio, Tong,
and Irby’s STELLA (2012) and Beck, McKeown, and Kucan’s Three-Tier Model (2002)
appear to agree that explicit academic vocabulary is essential or central to effective
reading and have outlined various strategies for teaching academic vocabulary to
elementary students. Some of these strategies include signal word of the day, in which
teacher had selected a word-of-the-day from readings and used the word throughout the
day to signal the beginning or ending of activities. As another aspect of the strategy, the
teacher first pronounced the word, students repeated the word in unison, and were asked,
at random, to use word in sentences throughout the day. According to Sibold (2011),
“through this method the use of repetition and the multiple exposures to the word
throughout the day increases the student’s retention of new words” (p.26). The talk-
through strategy with read aloud occurs when the teacher and the parents are encouraged
to talk through the definitions of words with students and give examples during read
aloud. The purpose is to allow students to hear the word in context (Sibold, 2011). The
use of an Academic Vocabulary Journal is a strategy that involves the student in writing
the definition of new words in a journal, and then using the word in a sentence. In the
final step the student is required to draw a picture to illustrate the word. Graphic
organizers are visual representations that show arrangements of concepts and/or
vocabulary words. Because graphic organizers use visual images, they are particularly
appropriate for ELL students (Sibold, 2011). Graphic organizers also help to link
definitions to examples (Colorado, 2007). The power of the game is also a noted strategy
where games, such as Bingo, Scrabble etc, are used to reinforce vocabulary words.
(Sibold, 2011).
Saenz et al. (2005) and Cruz de Quiros et al. (2012) agreed that structured story
retelling and fluency reading such as employed in the PALS and STELLA methods are
additional effective strategies. Oral language is among the most important skills a child
needs to acquire literacy (Slavin & Cheung, 2005). When a child is competent in one
language, these skills transfer to the new language. Therefore, it has been recommended
that oral language development be emphasized in early grades by English learning
programs until the student achieves a minimum level of proficiency (Saunders &
O’Brien, 2006). According to a researcher, vocabulary can be developed during story
reading in form of interactive, text-related dialogue (Calderon et al., 2005). Researchers
agree that another learning strategy used to facilitate listening comprehension is a post-
listening activity, such as story retelling, used to assess story comprehension (Cruz de
Quiros et al., 2012). For many students, story retelling has been found to offer students
the opportunity to orally reconstruct the story (Snow, 2002).
According to researchers, PALS provides more frequent and extended
opportunities to practice language than do traditional methods such as teacher-directed
guided reading. (Coelho, 1994; Long & Porter, 1985). During instruction implementing
the PALS method, peer-tutoring pairs read from texts that are matched to students’
reading ability, thus individualizing the approach. Because students receive feedback
from their peers, PALS affords students the opportunity to engage in self-talk strategies
without the need for accuracy in their responses (Gersten, Baker, & Marks, 1998). Saenz
et al. (2005) suggested that PALS provided opportunities to practice reading strategies
exhibited by strong readers. PALS should also provide a method for improving strategic
reading and the overall reading performance of students with LD. Fuchs and Fuchs
(2000), believes that in addition to traditional instruction, the use of collaborative
groupings and peer-assisted settings where students work together to boost each other’s
learning is one way of dealing with diversity issues in our education system.
Research evidence indicates that PALS is a strategy that is closely aligned with
theories of second language learning and second language proficiency, and appears to
provide contextual cues for teaching the cognitively demanding task of reading to ELL.
These factors seem to demonstrate that the PALS strategy is effective when used by ELL
students with LD (Baca & de Valenzuela, 1998; Coelho, 1994; Long & Porter, 1985).
Previous PALS studies also appear to indicate that as an intervention with grades three to
six, PALS improved the reading comprehension performance of ELL students with LD in
transitional bilingual education classrooms (Saenz, et al., 2005), but further research is
needed to determine the effectiveness of PALS on ELL with LD in an English only
education classroom.
It should be noted that some recent studies indicated that perhaps because of the
lack of attention to specific word reading skills, PALS may not be the optimal strategy to
use to improve the oral reading fluency of ELL but research showed that at grades three
to six, PALS improves the reading comprehension performance of ELL with LD, and
enhances students’ reading development. This was attributed to the fact that the focus of
grades two-six PALS procedures is not on how to decode unfamiliar or difficult to read
words in text. Teachers would need to depend on the Grade 1 or the modified version of
grade two PALS, which includes a detailed strategy targeted on the development of
word-level skill (Fuchs et al., 2001).

METHODOLOGY
Design of the Investigation
The participants were selected from an English only emersion program. The
classrooms selected for this study were determined to have a minimum of two or more
English Language Learners (ELL) students who were also identified with Severe
Learning Disabilities. To be eligible to participate, all students were enrolled in English
only emersion classes and each classroom had at least two ELL students identified as
having LD with Resource Specialist Program (RSP) services. All students in each
classroom participated in the Peer Assisted Learning Strategies (PALS). Two General
Education teachers in a fourth and fifth grade English only classroom and one RSP
teacher from one school site of one school district in Southern California agreed to
conduct study in their classrooms. These teachers are colleagues of co-investigator. Each
general education teacher taught all subjects including reading while the RSP teacher saw
the students, at various times each week, for an hour and reinforced areas of weakness
which included reading. Thus, the amount of time devoted to reading instruction was
controlled by the school schedule. Each participating teacher taught only one class
included in the study.
Population
Five elementary students were purposively selected to participate in this study as
the treatment group. Teachers were asked to provide demographic data regarding students
in their classrooms. Based on the data obtained; the ELL students were identified and
grouped. Then from the ELL student lists, those with Learning Disabilities were selected.
All students were identified by their school district as ELL with SLD, and were assessed
to be at “below basic” or “far below basic” grade level in reading, as determined by
California state eligibility criteria. These criteria include California English Language
Development Test (CELDT) and California Standardized Test (CST) test scores.
Students CELDT levels range from EI to I, in grades fourth and fifth, ages nine years old
through eleven years old. For the treatment group three are males and two are females.
All student subjects came from low income to middle class income households, and had

Treatment
For this study, training materials, classroom materials, teacher and student
training materials, and reading activities were part of the district curriculum. "The
Imagine It” by Mcgraw Hills (Bereiter, 2009).) Reading curriculum materials were used
together with online created reading passage worksheets that included reading passage
and follow up comprehension questions (see appendix). Training of teachers occurred at
regular staff development meetings. PALS sessions were conducted during regularly
scheduled reading instruction, three times a week, for thirty minutes each session. The
duration of PALS treatment was 10 weeks; this did not include the one-week pretest
period, or the week-long post-test phase. Teacher training time also occurred prior to the
10-week treatment. Teachers paired students based on their reading levels. Students with
advanced scores were paired with those with scores at far below or below basic. Pairs
were rotated every three weeks. Within each pair, during each lesson, both students
served in the role of tutor and tutee. For this study, during PALS, students engaged in the
reading activity described below.
Partner Reading with Story Retelling
During Partner Reading, each student read aloud for five minutes. For the first
five minutes of partner reading, the higher level score reader read while the lower level
score reader serve as tutor. As a tutor, students were taught to listen for different kinds of
errors. Errors included: saying the wrong word, adding a word, leaving out a word, or
taking longer than four seconds to read a word. When a student made one of these errors,
the tutor responded by saying, “Stop. You missed that word. Can you figure it out?” If
the tutee was able to read the word within four seconds, the tutor said, “Good. Read that
sentence again.” If the tutee did not figure out the word within 4 seconds, the tutor said,
“That word is______. What is the word?” then, the tutee repeated the word and the tutor
said, “Good. Read that sentence again.” When neither student knew the word, the tutor
circled the word and raised his or her hand to signal the teacher for help. During the Story
Retelling segment of Partner Reading, the lower level score reader of the pair retold in
sequence what was read in the previous ten minutes. Tutors prompted their partners by
using the phrases, “What happened first?” and “What happened next?” and continued the
process for five minutes. Students were provided a cue card as a guide. (See fig. 1)

Materials
In this study, teachers selected materials of choice to be used with the PALs
reading strategy. Some examples of materials that teachers selected were basal text,
passages from the “Read Naturally program, library books, and content area books.
Teachers selected books or reading materials appropriate for the lower level score student
of the pair. Thus, across a given classroom, pairs read from different books or passages.
Teacher Training
Teachers received professional development training surrounding the PALS
strategy, at staff meetings. The trainings were conducted by a colleague who was (the
co- investigator for this study). Teachers were first given an overview of PALS
procedures. Then, teachers were given the opportunity to practice the PALS activities
with colleagues, to gain a better understanding of the intervention. The emphasis of the
trainings was on implementing the PALS technique with their students.
Student Training
The set-up procedures (e.g., student roles, student materials, and rules), Partner Reading
and Story Retelling were taught by the participating teachers to the students in the study,1
week prior to the beginning of the ten weeks of PALS implementation. This training
required three 45 minutes training sessions. During the three training sessions, teachers
modeled key procedures and allowed students to role-play. The Co- investigator was
present each day of the trainings to provide assistance to the classroom teacher as
necessary. This assistance consisted of helping the teacher set up and organize materials
prior to training lessons, modeling peer-tutoring strategies with the teacher, and
monitoring students to identify pairs demonstrating difficulty.
Measures
This study, focused on partner reading with story retelling aimed at increasing
comprehension. All students of focus for the PALS treatment were given a reading
comprehension pre-test and post-test using the Comprehension Reading (CORE) Reading
Maze Comprehension Test appropriate for their reading placement grade level (see
Appendix A and B) to determine their reading comprehension level before and after
treatment (See table 3). During the timed Maze administration, the reader silently read
the Maze passage; whenever he or she encountered a response item, the reader circled the
word from the three choices that best restored the meaning of that segment of the
passage. The reader continued until time expired. A good description of the CORE
Reading Maze Test passages and administration techniques is available in using
Curriculum- Based Measurement (CBM) manual (Fuchs & Fuchs, 2007). Student
subjects were, also, given weekly reading comprehension quizzes. Scores were collected
and analyzed. (See table 2 below). The weekly quizzes consisted of a reading passage
with follow-up questions (see Appendix C and D). Quizzes were administered by the
RSP teacher during the students’ RSP service hours. The goal target score for all students
was a minimum of 80%.

You are being asked to allow your child to participate in a research study. Before you give your permission, it is important that you read the following information and ask as many questions as necessary to be sure you understand what your child will be asked to do. Investigators: Angela Nadozie, BS in Geography, Multiple Subject Teaching Credential, Special Education Teaching Credential (M/S). I am, currently, a student in the Special Education Master’s program and I am conducting research on a project that will help me complete my coursework as well as expand knowledge base in the field of Special Education with specific emphasis on Reading strategies for ELL students with LD. Caron Mellblom-Nishioka, Ed.D. is the faculty mentor for this research. Dr. Mellblom holds a Bachelors and a Masters degree in Speech Language Pathology and a Clear Speech Language Services Educational Authorization. She also holds a Doctorate in Special Education with and emphasis in Learning Disabilities and University Teaching. Dr. Mellblom is full professor and has been with CSU Dominguez Hills for 20 years. Purpose of the Study: The purpose of this study is to determine if Peer Assisted Learning Strategy (PALS) reading strategies benefit third through fifth grade English Language Learners (ELL) students with learning disabilities in a regular English only classroom setting. In this research study, we are evaluating whether the reading intervention strategy would improve students reading comprehension skills. All students in the classroom will participate in PALS and research will take place during regular school hours. For the purpose of this study, data will be collected and reported only on study participants. These are selected students who have been identified as ELL by their school district as determined by California state eligibility criteria, tested at “Far below” or “Below” in previous California Standardized Test (CST) reading test and diagnosed with Learning Disabilities (LD).
Description of the Study: This research study, attempts to evaluate the effectiveness of the reading intervention strategy to improve students’ reading comprehension skills. PALS are class wide peer-tutoring strategy with different grade level versions. The grade 2-6 version of PALS includes three main activities: partner reading with retelling, paragraph shrinking, and prediction relay activities aimed at increasing strategic reading behavior, reading fluency, and comprehension skills. For this study focus will be on reading comprehension.
I. The first step in this study requires your child to complete a fluency reading assessment to determine his/her reading level using the “Read Naturally” reading comprehension assessment tools.
II. The second step involves your child’s participation in a 30 minutes of PALS instruction three times a week, for 10 weeks where he/she will be paired with a peer who tested advanced in reading and together they read level appropriate texts from various content areas in the “Imagine It” program by Mcgraw Hills, and using given guidelines check for comprehension, then tested on weekly for reading comprehension growth trend. Study participants will be tested on reading.
III. The final step in this study includes a final reading comprehension assessment that evaluates if the PALS intervention strategy was beneficial.
Risks or Discomforts: Risks involved in this study will be minimal. Subjects may become aware of their reading level as compared with typical peers and begin to show signs of discomfort. To help minimize the situation students will alternate peer partners every 3 weeks and points given for efforts. Benefits of the Study: It is reasonable to expect the following benefits from this research: improved reading skills and higher student achievement on reading assessments. But, I cannot guarantee that you or your child will receive any benefits from this study. This study can improve the special education institute by providing an evidence-based effective reading strategy for ELL students with LD. Confidentiality: Your child’s name will not be used if data from this study become published. Every effort will be made to keep assessment records, research records, and other personal information confidential.
Incentives to Participate: No compensation or incentive will be offered to students. Voluntary Nature of Participation: Participation in this study is voluntary.
