Could an Interactive-balanced Environment for Reading Acquisition Overcome the Triad Risk Factors: Low Socioeconomic Status, Low Literacy Skills and Language Properties?

A large number of the scientific efforts that have investigated the issue of Arabic language acquisition have mainly focused on the implication of its Diglossic nature and orthographic complexity in reading acquisition. However, the interplay of the two factors and low-socio economic background was not addressed sufficiently. The current study follows the progress in literacy skills among at-linguistic risk Arabic native speaking kindergarten children throughout 2nd grade, and assesses its impact on reading and writing acquisition in a Diglossic context. Twenty-five at literacy risk children and 181 heterogeneous children (resembling the heterogeneity of Socioeconomic Status (SES) and literacy background in regular classes) took part in the study. The effects of an interactive balanced reading and writing learning program were evaluated. Children were assessed both at the end of kindergarten and at the beginning of 2nd grade in the following domains: discourse, listening comprehension, phonology, morphology, syntax and vocabulary. In the post-test, reading measures were included. The results of the study indicate that the learning program succeeded in bridging the gaps in literacy skills between the at-risk children and their heterogeneous peers. However, lower performance was observed in reading measures among the former.


Introduction
For most people, literacy development is an intuitive process that commences in early childhood, while relying mainly on one's exposure to language.However, when socio-economic factors adjoin Arabic Diglossic circumstances and its orthographic complexity, the development of emergent literacy skills is obstructed, affecting later reading and writing acquisition and academic success (e.g.Abu-Rabia, 2000;Hussien, 2014aHussien, , 2014b;;Lundberg, Larsman, & Strid, 2012;Makoul, 2006;Morgan, Farkas, Hillemeier, & Maczuga, 2009;Saiegh-Haddad, 2003, 2004).Cunningham & Stanovich (1997) have documented the long-term implications of reading acquisition difficulties where reading performance in first grade correlated with reading comprehension, vocabulary and general knowledge in 10th grade.Accordingly, the current study attempts to investigate the impact of the interplay between Arabic linguistic features and low SES background on literacy skills and later on reading acquisition.
Arabic script is cursive (e.g.bird is written ‫)ﻋﺼﻔﻮر‬ where visual similarity is found between some of the letters, differentiated only by the number or position of dots placed under or above them (e.g.‫ث‬ ، ‫ت‬ ، ‫.)ب‬ Furthermore, out of 28 letters, 22 letters have four shape forms which alternate with adequacy to their position in a word: Initial ‫,)ﺑـ(‬ middle ‫,)ـﺒـ(‬ Final ‫)ـﺐ(‬ and separate ‫)ب(‬ forms) Abd El-Minem, 1987).The six remaining letters have only two variations: separate and final.
Accordingly, different scientific efforts have addressed the impact of the visual characteristics of Arabic orthography on reading acquisition.Eviatar, Ibrahim and Ganayim (2004) indicated that the identification of visually similar letters occurs much slowly.In addition, the perceptual load of Arabic orthography was correlated with processing difficulties in reading Arabic where visual short-term memory accounted for the differences between skilled and poor readers (Abu-Rabia, Share, & Mansour, 2003;Abdelhadi, Ibrahim, & Eviatar, 2011;Ibrahim, Eviatar, & Aharon-Peretz, 2002).Mohamed, Elbert and Landler (2011) suggested that visual and spatial abilities have potential role in reading fluency, especially in early stages of acquisition.

Socio-Economic Background and Emergent Literacy Skills: The Route to Reading Acquisition
Upon commencing first grade, children are highly motivated and excited to pursue their scholastic education, but are soon challenged by the turbulent journey towards literacy acquisition, already starting from early childhood and manifested differently in its manner of occurrence and pace.Different factors operating simultaneously in the child's surroundings influence emergent literacy skills and subsequent reading acquisition, such as socio-economic background, language and meta-linguistic skills development (Pianta & Cox, 1999;Ramey & Ramey, 1999).These factors amplify the difficulties experienced by Arab first-graders during the significant transitional phase, while confronted with the challenge of acquiring reading and writing in a markedly discrepant variation of their native spoken language.Emergent literacy skills are the building blocks of reading development, predicting children's reading skills in elementary school (e.g.Aram, Korat, & Hassunah-Arafat (2013);Cabell, Justice, Konold, & McGinty, 2011;Lonigan, Burgess, & Anthony, 2000;Mol, & Bus, 2011).Socio-economic status has been found to impact children's cognitive development, especially language functions (Hackman, Farah, & Meaney, 2010;Jednoróg, Altarelli, Monzalvo, Fluss, Dubois et al., 2012).Many studies have pointed out the relationship between early literacy skills and academic success, indicating a significantly lower academic performance when comparing groups from low SES to their counterparts from more advantageous socio-economic backgrounds (e.g.Aikens & Barbarin, 2008;Lundberg, Larsman, & Strid, 2012;Morgan, Farkas, Hillemeier, & Maczuga, 2009, 2012).Such a discrepancy is already apparent in early stages; children from low SES begin formal schooling with lower meta-linguistic skills and limited exposure to literacy fostering environments and thus considered to be at-risk for reading difficulties (Lundberg, Larsman, & Strid, 2012).Specifically, Makhoul (2006) and Makhoul & Ibra-him (2012) stressed the necessity of mastering the required phonological and oral language skills in Arabic reading and writing acquisition, pointing out the importance of early exposure to literacy activities and enhancing children's interest, enjoyment, and motivation in reading activities.
The interaction of Arabic socio-linguistic context with environmental risk factors such as low SES hampers adequate reading acquisition.Data collected for international literacy tests, such as PIRLS ( 2006), showed that Arab native speakers have poor achievement in reading.In Israel, the reading scores of Arabic-speaking fourthgrade students were significantly lower than their Hebrew-speaking peers, stemming both from the Arabic Diglossic nature and the socioeconomic inequality between these two sectors (Zuzovsky, 2010).Thus, a multicomponential compensating approach is required.

The Current Study
The aim of the current study is to investigate the conjoint effect of the Arabic Diglossic nature, its orthographic characteristics and low SES on literacy skills and reading acquisition.Specifically, we assessed the effect of promoting literacy knowledge on later reading skills among low SES at-risk children, while following their progress from kindergarten throughout second-grade.The children were assessed for their discourse and listen-ing comprehension skills, morphological, phonological, syntactic and vocabulary knowledge, both before the program commencement and after its termination.In addition, reading assessment (technical and reading comprehension) was included in the post-test.
Accordingly, the current study attempted to investigate the following questions: 1) Will at-linguistic risk preschool children demonstrate an initial lag in literacy skills (phonology, discourse, listening comprehension, morphology, syntax, and vocabulary) when compared to their heterogeneous classmates?
2) How will an interactive-balanced learning program benefit literacy domains in each group?
3) How will multi-dimensional literacy promoting program affect later reading performance and comprehension?
4) Is there a relationship between the assessed literacy skills after working in the learning program and reading performance in both groups?

Participants
206 Arabic native speaking children from five different Arab northern schools in Israel were selected to participate in this study.One school was considered as a low SES school; its target population arrives mainly with low literacy skills and limited exposure to written language.In the low SES school, 25 children were assigned to atlinguistic Risk group (LR), whereas the other 181 children (from the other four schools) were assigned to the Heterogeneous Group (HG), resembling the heterogeneity in SES and literacy skills in a regular class.Children with neurological disorders, learning disabilities, and emotional difficulties were excluded from the study (Table 1).

Measures
A literacy assessment battery was devised and validated (Makhoul, 2006;Makhoul & Ibrahim, 2012) which included: discourse, listening comprehension, phonological awareness, vocabulary, and reading measures.The testers documented children's answers and responses.The measures are described in Table 2.

Reading Literacy Program-"Arabic Is Our Language"
Upon commencing first grade, all the children participated in "Arabic is our Language" reading program, which was based on the interactive model for reading and writing acquisition (Adams, 1991), taking into account the role of its four processors: context, phonology, orthography and semantics and that was adapted to the new curriculum of Arabic Language (State of Israeli Ministry of Education, 2009).The program development was carried out by the team of the Arabic Language Department at the Center for Educational Technology (CET) (Makhoul, Iskandar, Ibrahim, & Hijazi, 2010).
The instructional format of the program included two stages, emphasizing a direct instructional approach that sets grounds for developing reading automaticity to ultimately derived meaning.At the first stage, the program focuses on fostering phonological awareness, orthographic knowledge, decoding skills, listening comprehension, and discourse.The second stage focuses on developing reading skills fluency of short texts, without reliance on context, while promoting comprehension skills and listening comprehension, besides to acquisition of appropriate spoken conversation and linguistic knowledge.
The program takes into account both the cognitive and developmental aspects of reading acquisition, and  Discourse Skills Measure (DSM) (Makhoul & Ibrahim, 2012) Introductory conversation The children were asked to answer a series of questions addressing their families, preferences and hobbies.
Picture description The children were presented with a picture and were asked to describe it.

Storytelling
The children were required to tell a story, following the presented picture.

Story comprehension
After listening to a story twice, a story recall-task was followed (Short-Term Recall).Then, they were asked to answer orally a series of comprehension questions and were ultimately asked to recall the story after 20 min delay (Long-Term Recall).
The story recall and answers were assessed by indices of Makhoul (2006).

Instructions' comprehension
Nine items were included in this task, requesting the children to follow the tester's instructions.For example: "draw a kite above the longer pen".

Sentence-picture matching
The children were required to choose the sentence that best describes the presented picture (out of five sentences read by the tester).
Arabic Phonological Awareness Measure (APAM) (Makhoul & Ibrahim, 2012) All the used tasks were adapted to Arabic based on the Reading Readiness Screening Tool (RRST) developed by Learning Disabilities Association of Alberta (2009).

Auditory Word detection
Five sentences were presented.The children were asked to count the number of the heard words following each sentence by using their finger.
Syllable Detection The children were asked to map the number of syllables appearing in a heard word by "clapping" each syllable out.

Phoneme detection
The children were asked to sound the heard phonemes in the presented words.Due to their insufficient sensitivity to short vowels when blended with consonant sounds, they were only evaluated for their capacity to map consonant sounds.For example, the word " ‫َﺐَ‬ ‫َﺘ‬ ‫"ﻛ‬ (/kataba/) consists of 3 consonants and 3 short vowels (/a/) represented by the diacritical mark fatħa ‫ـ(‬ َ ‫.)ــ‬

Rhyme generation
The task requires generating a rhyming word with previously sounded target words or pseudo-words.
Standard Arabic Morphological Awareness (SAMA) Adapted and revised from Abu-Ahmed ( 2008)

Morphological awareness
The task assesses awareness to word morphological structure in written Arabic.Each item includes a pair of real and pseudo words, allowing assessment of the different aspects of inflectional structures in Arabic (gender, tense, number, person and mood).The children are asked to select the word with the corresponding morphological structure.

Test of Receptive Oral Grammar
Adapted to Modern Standard Arabic from Bishop (1994) The children were presented with four pictures and were asked to select the picture corresponding to the heard word or sentence.The test includes 20 syntactic categories (e.g.negative form, adjectives, comparison forms, passive forms…).
Arabic Vocabulary Measure (AVM) (Makhoul & Ibrahim, 2012) Expressive Vocabulary The test consists of two parts.The first part includes 15 items, requiring the children to name the presented pictures.
In the second part, the children are asked to point to the picture that corresponds to the heard word.

Generalization
The children were asked to draw a line between each pair belonging to the same category.
Odd Word Out Four pictures were presented and the children were instructed to draw a circle around the picture that doesn't belong and to justify their answer.

Story Sequencing
The children were presented with 4 pictures and were asked to sequence the pictures in the correct order, to create a story and tell it.

Continued Arabic Reading and Comprehension Measure (ARCM)
Pseudo-word reading (Abu-Ahmed, 2008) To assess decoding skills, six items are introduced, including one exemplary item.

Context-free Oral Word Naming
The children were asked to read five familiar words that they have previously been exposed to during the program.
In addition, the children were presented with another five unfamiliar words (context free).

Text Reading and Comprehension
The children were asked to read a short passage (51 words).They were assessed on: Accuracy (Number of correct read words) and Fluency-Rate (Time of reading in seconds).
In addition, they were asked to retell the story and to answer a set of questions dealing with the read story (their performance was assessed by Makhoul gauges ( 2006)).
1 The tools were briefly discussed due to their large amount; if necessary, we could add them as an appendix.

Assessment Procedure
The first assessment was held during May-June 2011, at the end of kindergarten year whereas the second assessment was held at the start of second-grade during September-October 2012.In both assessments, the literacy battery test was administered by qualified testers for 45 minutes.Furthermore, in the post-test, the children's reading skills were assessed (technical reading and reading comprehension).

Statistical Analysis
An overall mean score was calculated for each domain, on pre-test and post-test.Paired-samples t-test was conducted to assess the children's progress over the program period.An independent-sample t-test was carried out to compare literacy knowledge and reading skills between the HG and LR groups, both in the pre-test and posttest.In addition, effect sizes were calculated where 0.20, 0.50 and 0.80 are considered weak, moderate and strong, respectively (Cohen, 1977;Rosenthal & Rosnow, 1984).
A series of multiple linear regression analyses were conducted in order to reveal the effects of the six domains in the learning program on reading accuracy and reading comprehension.
Ultimately, Pearson correlation coefficients were calculated to assess the relationship between the different literacy skills and reading.Furthermore, Simple Interactive Statistical Analysis (SISA) was calculated to assess whether differences were found in Pearson correlations between HG and LR.

Initial Differences in Literacy Skills between LR and HG in Preschool
For the pre-test, an independent-sample t-test was performed to assess the initial difference in literacy skills among HG and LR groups (kindergarten, end of year).The differences in mean scores in the various literacy domains are presented in Figure 2.
Pre-test results indicated an initial gap between the two groups; higher literacy knowledge was observed in the HG when compared to LR.

The Efficacy of "Arabic Is Our Language" in Bridging the Gaps between LR and HG Groups in the Different Literacy Domains
In the post-test assessment, no significant difference was found in literacy skills between LR and HG groups, except in vocabulary (t(204) =2.89, p < 0.01) (see Figure 3).This Post-test results showed the efficacy of "Arabic is our Language" program in promoting literacy skills and closing the gaps between the LR and HG groups, except in vocabulary knowledge.

The Effect of Literacy Skills on Reading Performance
An overall mean score for reading accuracy, composed of the pseudo-words, context-free words and text reading mean scores was calculated.Figure 6 presents the differences in reading achievements between HG and LR group.
An Independent-sample t-test was carried out to assess the difference in reading accuracy between HG and LR group.Significantly, higher performance in overall reading accuracy was observed among HG group (t(204) = 5.61, p < 0.001).Furthermore, HG group showed a significantly higher performance across the different reading accuracy measures: pseudo-words (t(27.65)= 3.09, p < 0.01), context-free words (t(27.57)= 4.53, p < 0.001) and text reading (t(204) = 5.57, p < 0.001).
To compare the difference in reading rate, dependent-sample t-test was conducted.In Figure 7, reading rates in the different reading measures are presented.The HG group reading rates were significantly faster when compared to LR group in pseudo-words (t( 202 Differences in reading comprehension were also assessed.An overall mean score was calculated (composed of the children's scores in "story recall" and "comprehension questions" measures of the read text).Independent-sample t test points out significantly higher performance in HG group (M = 66.32,SD = 20.08)when compared to LR group (M = 45.13,SD = 22.27).In order to estimate the conjoint effect of fostering the different literacy skills, a multiple linear regression analysis was conducted to evaluate the degree by which the different literacy measures predicted reading accuracy (decoding) and reading comprehension using stepwise interring method of the domains into the model (according to their contribution).
Table 3 presents the indices of the relative strength of each domain with relation to reading accuracy.In HG group, phonology and vocabulary accounted for 35% of the variance in reading accuracy (F(2, 178) = 48.48,p < 0.001), while discourse, morphology, syntax and listening comprehension did not appear to add predictive strength beyond the former measures.In LR, syntax and vocabulary accounted for 53% of the variance of reading accuracy (F(2, 22) = 12.25, p < 0.001) while the other domains (discourse, phonology, morphology and listening comprehension) did not contribute to the explained variance.
From Table 4 we can conclude that amongst HG, listening comprehension, vocabulary and syntax explained 35% of the variance in reading comprehension (F(3, 177) = 31.52,p < 0.001), the other domains discourse, phonology and morphology did not add to the explained variance.

Differences between Reading and Listening Comprehension
In each group, a dependent-sample t test was conducted to compare between listening and reading comprehension skills.Significant difference was found in both HG (t(180) = −2.91,p < 0.01) and LR group (t(24) = −5.80,p < 0.001) (see Figure 8).

In Each Group, Differences between Reading and Listening Comprehension Were Found
In the HG group, higher performance was noted in listening comprehension (M = 69.69,SD = 13.75)compared to reading comprehension measure (M = 66.32,SD = 20.08),(t(180) = −2.91,p < 0.01).Similarly, in the LR group, better listening comprehension skills (M = 65.72,SD = 11.) were observed when compared to reading comprehension (M = 45.13,SD = 22.27), (t(24) = −5.80,p < 0.001).Interestingly, on the story recall measure, significantly higher performance was obtained in the reading com-    prehension task when compared to listening comprehension, both in the LR and HG groups, (t(180) = 3.35, p < 0.01), t(24) = 3.97, p < 0.01), respectively.In contrast, in both groups, no significant difference in performance was observed in the listening comprehension questions when compared to reading comprehension questions.In the HG group, no significant difference was observed in their performance in the reading comprehension questions measure (M = 57.32,SD = 24.23)and listening comprehension questions measure (M = 60.55,SD = 22.30).
Similarly, no difference in performance in the reading (M = 51.67,SD = 26.57)and listening (M = 55.60,SD = 18.56) comprehension questions measures was found among the LR group.

Reading Performance and Literacy Skills Correlations
To assess the relationship literacy skills and reading performance (after learning in the program), Pearson's correlation coefficients were computed for each group.In addition, the relationship between the different literacy domains was assessed (See Table 5).Table 5 points out moderate-strong positive correlations between all the assessed literacy skills and reading performance in HG group.Most prominently, the results point out a moderate correlation values between listening and reading comprehension (r = 60, p < 0.01), vocabulary and reading comprehension (r = 58, p < 0.01), text reading measure and reading comprehension (r = 96, p < 0.01) and to a strong positive correlation between pseudo-word reading and context-free oral word reading (r = 71, p < 0.01).
In LR group, though weaker correlation values were found when compared to HG group, a similar pattern of results was observed.Moderate positive correlations were obtained between reading and listening comprehension and between vocabulary and reading comprehension, (r = 46, p < 0.01), (r = 55, p < 0.01), respectively.A very strong positive correlation was found between text reading and reading comprehension (r = 0.97, p < 0.01).In addition, a strong positive correlation was found between pseudo-word and context-free oral reading measures (r = 0.73, p < 0.01).
In contrast, among LR, non-significant correlations were found between listening comprehension and text reading (r = 0.28), morphology and text reading (r = 0.39), context-free oral reading and listening comprehension (r = 0.34), vocabulary and listening comprehension (r = 0.34), morphology and context-free oral reading (r = 0.35) and between morphology and phonology (r = 0.36).
Despite the small and non-persistent differences, similar correlations patterns were found between the two groups, but the differences in correlations were statistically non-significant.The correlations are similar across the literacy domains assessed in the current study independently from the belongingness to group (LR/HG), and show a similar pattern of learning, except between syntax and pseudo-words reading (Z = −2.22,p < 0.05), where stronger correlation was obtained in LR group (ρ = 0.75, p < 0.01) when compared to HG group (ρ = 0.44, p < 0.01) This difference depends on the starting point between the two groups as explained in the discussion.

Discussion
In this study, we attempted to investigate the impact of literacy skills development on reading acquisition among at-risk Arabic speaking children.Consequently, the progress in the different literacy domains of the at-risk group (LR Group) was monitored and compared to their more advantageous counterparts (HG Group), following the implementation of interactive-balanced learning program for reading and writing acquisition.Literacy assessment was carried out on kindergarten end of year, prior to the program commencement and in second grade, after its termination.In addition, a post-test reading assessment was included to investigate the impact of literacy knowledge progress in reading skills.
The results of the present study indicate clear lag in the majority of the assessed literacy domains (phonology, morphology, syntax and listening comprehension) at kindergarten where the HG group demonstrated an initial superiority when compared to the LR group.The obtained results fall in line with previous findings addressing literacy development among at-risk children from low SES, stressing the necessity for early detection and intervention (e.g.Makhoul, 2006;Makhoul & Ibrahim, 2012;Lundberg, Larsman, & Strid, 2012).
In second grade, the post-test assessment pointed out the efficacy of "Arabic is our Language" program in promoting literacy skills and closing the gaps between the LR and HG groups, except in vocabulary knowledge.Despite the immense progress achieved in literacy skills, the LR group reading performance was lower than their peers, which, in part, may be attributed to their lower vocabulary knowledge.The DVC model-Decoding, Vocabulary and Comprehension (Perfetti, 2010) conceptualizes the reading skill in terms of the interplay between its cognitive and linguistic primary constituents: vocabulary (depth and width), decoding (including orthographic knowledge and phonology) and comprehension (ranging from basic sentence comprehension to more complex text representation that requires inference process).Though the three components are reciprocally interlinked, DVC model assumes that comprehension shares a direct connection solely with vocabulary, where word meaning mediates between decoding and comprehension, supplying feedback to the reader's efficacy in word identification.Accordingly, despite the progress that was made in literacy knowledge, intensive and successive intervention should be followed in order to compensate for the accumulated gaps resulting from the interplay of disadvantageous socio-economic background and impact of Arabic Diglossic context and orthographic features.
In addition, after participating in the program, HG has showed a great progress in literacy skills, which was also reflected on their reading skills, including comprehension.As previously suggested by Abu-Rabia (1999, 2000a, 2000b, 2003) and Makhoul (2006), the results indicate that multi-componential balanced literacy pro-moting program is required to compensate for the gaps in literacy skills as a result of Arabic the Diglossic nature and in overcoming its orthographic complexity.It's worthy to note that the program has demonstrated its efficacy despite the great variance in the children's literacy skills, thus stressing its adequacy as a reading acquisition program.
In order to shed light on the source of found discrepancy in reading skills between HG and LR group, we have investigated the children's performance, while taking into account both accuracy and speed components in the different reading measures pseudo-word, context-free word and text reading.The results points out higher ratio of reading errors among the LR group in all reading measures (See Figure 3).Comprehensive observation on the type of reading errors in the LR group revealed a wide spectrum of errors, in part resulting from the orthographic complexity of Arabic orthography (Hussein, 2014a) and the impact of the visual load as previously documented (Abdelhadi, Ibrahim, & Eviatar, 2011;Hussein, 2014b;Taha, 2013).Many of these errors included phoneme omissions (short vowels represented by diacritical marks) and visually similar confusion in letters.
Multiple regression analysis showed that in HG group phonology and vocabulary explained 35% of the variance in reading accuracy.Also in reading comprehension, listening comprehension, vocabulary and syntax predicted 35% of the variance.Within LR, 53% of the variance of reading accuracy was explained by syntax and vocabulary, 50% of the variance of reading comprehension was explained by phonology and syntax.
In terms of reading rate, for the context-free word and pseudo-word reading measures, higher speed average was obtained in LR group in comparison to HG group, (See Figure 4), indicating a trade-off between speed and accuracy and to a lack of reading automaticity that hinders reading comprehension (e.g., Samuels, 2006).In the text reading measure, the similarity in the obtained reading speed average can be explained by the reciprocal nature of comprehension and decoding, where context facilitates word decoding.Indeed, according to the selfteaching hypothesis, contextual information plays a vital role in word decoding, especially when reading is less proficient (Share, 1995(Share, , 1999)).
In addition to their hindered reading, when addressing the source of difficulties found in reading comprehension among LR group, the obtained pattern of results replicate previous finding linking it to listening comprehension skills.According to the simple view of reading comprehension, reading comprehension is the outcome of skillful decoding and listening comprehension (Gough & Tunmer, 1986;Hoover & Gough, 1990).Studies have shown that comprehension is reliant on language processing, requiring semantic processing, vocabulary and grammatical knowledge (e.g.Nation et al., 2004;Nation & Snowling, 1998a, 1998b;Cain et al., 2001).Indeed, despite the progress made by the LR group after the termination of the learning program, significantly lower performance was yet found in listening comprehension when compared to the HG group, which also may account for their poor reading comprehension.
To establish the relationship between the different literacy measures and reading performance, Pearson's correlation coefficients were calculated, pointing to their interconnectedness and the correlations between the domains.Thus, these findings fall in the line with several former studies (see Adams, 1991;Perfetti, 2010;Rand Reading Study Group, 2002).The obtained results stress the multi-componential aspects of reading in Arabic, requiring a broader perspective, transcending phonology while considering other precursors of reading, such as morphological awareness (e.g.Mahfoudhi, Elbeheri, Al-Rashidi, & Everatt, 2010;Makhoul & Ibrahim, 2012;Mutlak, 2010).In the current study, positive significant correlation was found in the HG group between morphology and all reading measures with listening comprehension.In the LR group, positive significant correlations were obtained between morphology and reading comprehension, listening comprehension and pseudoword reading.Other relationships were also observed in both study groups such as, between syntactic knowledge and listening comprehension, listening comprehension, replicating a previous finding that pointed out the role of syntax in comprehension (e.g.Bentin, Deutsch, & Liberman, 1990;Bowey, 1986aBowey, , 1986b;;Perfetti, 2004).In both groups, pseudo-word and context-free oral reading highly correlated pointed out the dependency on decoding process in the first stages of reading (Al-Mannai & Everatt, 2005;Saiegh-Haddad & Geva, 2008;Taibah & Haynes, 2011).
On the other hand, only modest correlations were obtained between the different literacy skills (phonology, morphology, vocabulary and syntax), reading measures (pseudo-words, free-context oral word and text reading) and comprehension measures (listening and reading comprehension) in LR group.Though significant progress has been made in literacy skills, following their participation in the program "Arabic is our Language", the LR group has arrived with significantly lower literacy knowledge as a result of their deprived socio-economic context that adds up to the limitations induced by the Arabic Diglossic nature.Consequently, lower reading perfor-mance is still found when compared to HG group.
Contrary to reported contribution of morphological processes in Arabic reading, only a weak correlation between morphology and reading measures was found.Such finding might be explained by the superiority of phonological processes in the first stages of Arabic reading acquisition that gradually incorporates morphological knowledge as it builds up during schooling years.As a result, it would be beneficial to investigate the impact of the progress in morphological knowledge in predicting reading performance in later stages.
The non-significant differences in Pearson's correlations between HG and LR (except in pseudo-word reading and syntax) points out a similar relationship between the various domains, and suggests that the administrated learning program has been successful in bridging the gaps in literacy skills among LR group, observed since kindergarten.
To understand the significant difference in Pearson's correlation between HG and LR in syntax and pseudoword, we have to analyze the hidden relationships that underlie those two domains.Within LR, the correlation between those domains was stronger than the correlation in HG.The difference could be explained from two points of view.
The first, there was a difference in decoding and comprehension performances between LR and HG.For struggling readers as LR children, reading a new text or word is actually a pseudo-word reading because they have difficulties in decoding.Furthermore, in Arabic, one word could replace a whole sentence in English because of the high morphological density of Arabic.In this view, one word has its syntactic and morphological entity.As we know, decoding and comprehension correlate with syntax (Perfetti, Landi, & Oakhill, 2004), and syntax is correlated with vocabulary (Huggins, 1977;Marchman & Bates 1994;Tomasello, 2000) in which LR did not bridge the gaps in this domain with their counterparts in HG, and vocabulary is correlated to reading (Verhoeven & Perfetti, 2011).LR children are trapped in a circle in which one disadvantage leads to another.Perfetti, Landi, & Oakhill (2004) suggest that the role of syntax in reading may reflect differences in the development of functional language skills.The difference in the correlation in syntax and pseudo-word reading may point out differences in language skills.The second, struggling readers rely on contextual cues to decode words and derive meaning.However, how LR group with low vocabulary could construct meaning?For them, decoding words is pseudo-word reading.LR group did not bridge the gaps in vocabulary and vocabulary correlates with syntax.Concerning DVC model (Perfetti, 2010), their performances both in decoding and comprehension were negatively affected.Efficient utilization of contextual cues in reading depends greatly on syntactic processing.While reading Arabic text, intervening factors add difficulties to the reading process; the reading rate slows besides performing reading errors, which are for the most part of a syntactic background (Ibrahim, Eviatar, & Aharon-Peretz, 2007).
In conclusion, the results of the present study point out the contribution of "Arabic is our Language" as a multi-componential reading program, addressing both the cognitive precursors and developmental aspects intervening in reading acquisition (See Figure 2).

Conclusion
Fostering literacy knowledge amongst at-risk children is shown to be crucial in assisting them to close the gaps with their peers but is not sufficient for ensuring reading acquisition.Though progress was obtained in the LR group, the results stress the need for comprehensive, constructed and successive intervention in reading and writing acquisition that takes into account the challenges imposed on children as a result of the triad risk factors working on them: low literacy knowledge, the Diglossic nature of Arabic and its orthographic complexity and low SES background.
Thus, the key for ensuring a normal reading acquisition for these children is to learn in an interactive-balanced learning program for a prolonged period.
The contribution of the current learning program has also been successful in improving literacy skills among the children from more advantageous backgrounds, proving its adequacy to be implemented as a part of the Arabic language curriculum for the Arab sector.
Characteristics of the Arabic language bring difficulties and slow reading acquisition among native Arab children; findings teach us that with the right environment, taking into account the cognitive and developmental processes that underlie reading acquisition could bridge the complexities of the language characteristics and allow the learning process consistently and will benefit both among different students at-risk and among regular students.
With regard to the study implications for the scientific field, our results raise the necessity for constructing learning programs and developing early screening tools that are adapted to the characteristics of the Arabic language, taking into account the environmental and developmental aspects interacting and effecting normative literacy acquisition.Furthermore, in terms of pedagogical implications, our results emphasize the importance of developing and incorporating scientific-based learning materials in order to achieve optimal results when acquiring reading and writing.Ultimately, based on the collected data, our measures can be utilized as standardized assessment tools both by teachers and specialists in the field of learning disabilities and language pathologies.
It is worth noting that a follow up study will be conducted upon the students' commencement in fourth grade, after finishing their formal reading acquisition, to examine which of the assessed domains were more successful in predicting later reading performance.
