In this study an attempt was made to construct a multi-factor model predicting the development of reading literacy in the upper grades of primary school in the Netherlands for subgroups of 729 first language (L1) learners and 93 second language (L2) learners. Following a longitudinal design, it was explored to what extent the variation in reading literacy development in L1 and L2 from grade 4 to grade 6 can be explained from children’s word decoding, language, mathematics and nonverbal reasoning skills, reading motivation and self confidence as well as their home reading resources. The results showed that L1 and L2 learners differed in reading literacy skills, language, mathematics, and reasoning skills. Structural equation modelling showed that the reading literacy development in both L1 and L2 learners could be explained from decoding, language, mathematics and reasoning skills, as well as their motivation and self-confidence. A striking difference was the fact that home reading resources had an impact on reading literacy in L1 learners but not in L2 learners.

For a student to become a successful and productive adult in society, good reading skills are essential. To refer to the demands for literacy in today’s society the term reading literacy was introduced as “the ability to understand and use those written language forms required by society and/or valued by the individual” (Mullis, Kennedy, Martin, & Sainsbury, 2006, p. 3). Reading literacy and the factors that are associated with that ability have been a topic for study for many researchers. The Simple View of Reading states that reading comprehension is a product of two components; decoding and linguistic comprehension (Gough & Tunmer, 1986; Hoover & Gough, 1990). Decoding is the ability to transform printed letter strings into a phonetic code (Perfetti, 1985). Linguistic comprehension is, according to Gough and Tunmer (1986) “the process by which given lexical information, sentences and discourses are interpreted” (p. 7). Although many researchers have tried to modify, complicate and refute this theory (Joshi & Aaron, 2000; Adlof, Catts, & Little, 2006), there seems to be a consensus that these components form the basis of reading comprehension abilities (Perfetti, Landi, & Oakhill, 2005). However, Joshi, Williams, and Wood (1998) found that although the components of the simple view of reading, decoding and language comprehension accounted for most of the variance in reading comprehension, IQ was also a significant predictor. Another related factor is mathematics. Reading literacy and mathematics involve similar cognitive demands which could explain the relationship that is observed between reading and mathematics in several studies (Lerkkanen, Rasku-Puttonen, Aunola, & Nurmi, 2005). Lundberg and Sterner (2005) found close to forty percent of shared variance between reading literacy achievement and mathematics.
Background characteristics may also contribute to the variance in reading literacy. It has indeed been found that parents contribute to the reading abilities of their children through various environmental factors, such as motivational factors, reading literacy activities, and reading attitudes (Tabors & Snow, 2001). Snow and Beals (2006) demonstrated that besides literacy activities, such as reading a book together with a child, even those natural interactions between parent and child that occur during day to day activities can contribute to children’s literacy abilities. In a similar vein, de Jong and Leseman (2001) examined the impact of preschool home environment for later literacy development in primary school. They found that even after first grade word-decoding ability and reading comprehension were controlled for, home measures remained to have an impact on third grade reading comprehension. Reading can thus be seen as an activity which benefits from practice, and it can be assumed that for many children a great deal of that practice takes place at home. A positive and reciprocal relationship between children’s reading ability, the time they spent reading, and their reading motivation has indeed been found (Guthrie & Wigfield, 2000). Cox and Guthrie (2001) also made clear that, when other factors such as ability were controlled for, the amount of reading for enjoyment was predicted most highly by reading motivation. Another factor by which parents influence their children’s reading achievement is academic self-confidence. Parents’ positive beliefs and expectations about their children’s abilities have a strong influence on their children’s own beliefs about their academic abilities (Meece, Bower-Glienke, & Burg, 2006). Students who have positive experiences and believe that they will do well in school turn out to obtain better school results (Aunola, Nurmi, Niemi, Lerkkanen, & Rasku-Puttonen, 2002).
An important factor in children’s background is the language spoken at home. Several studies have shown that second language learners lag behind their first language peers in reading literacy skills (Droop & Verhoeven, 2003; Organisation for Economic Co-operation and Development [OECD], 2007; Mullis, Martin, Gonzales, & Kennedy, 2003; Mullis, Martin, Kennedy, & Foy, 2007; van der Veen, van der Meijden, & Ledoux, 2004). Second language students are often faced with the complex task of learning to read in a language they are not accustomed to speak before they enter primary education. Given that learning to read comes down to learning to connect the spoken form of a language with the printed form (Wang, Perfetti, & Liu, 2005), a problem for second language learners can be expected. Indeed, research has shown that problems with the spoken second language may have an impact on reading processes, especially in the domain of reading comprehension skills (Geva & Verhoeven, 2000; Verhoeven, 2000). Several studies have also shown that in case of a mismatch between children’s language abilities and the language being used in the school curriculum the reading motivation and self-confidence of L2 learners may be threatened (Aarnoutse, van Leeuwe, Voeten, & Oud, 2001; Guthrie, Coddington, & Wigfield, 2010). Besides linguistic factors, cognitive factors, such as mathematics and reasoning skills may also play a substantial role in the acculturation and reading acquisition of the L2 learner (Marks, 2005; van Diepen, 2007).
What are the differences between L1 and L2 learners in reading literacy, decoding, language, mathematics, and nonverbal reasoning skills, reading motivation and self-confidence, and home reading resources?
Can the reading literacy development of L1 and L2 learners to the same extent be explained from their decoding, language, mathematics, and nonverbal reasoning skills, reading motivation and self-confidence, and home reading resources?
A representative sample of 822 children from 48 schools participated in the present study. These children form part of the so-called PRIMA study, a longitudinal cohort study on the learning of language, mathematics and reading abilities among students in elementary education in the Netherlands (Driessen, van Lange, & Vierke, 2002). Seven hundred twenty-nine of the participants (340 boys, 389 girls) were first language learners with both parents born in the Netherlands, the remaining 93 students (54 boys, 39 girls) had parents originating from other countries (66% from Mediterranean countries, 20% from ex-colonies, 14% other countries) and were considered second language learners.
The level of reading literacy ability was assessed with the grade 4 and grade 6 versions of the standardized CITO Reading Comprehension Test (Staphorsius & Krom, 1998). This test consists of texts with multiple-choice questions which comprise a scale for reading literacy throughout the elementary grades. The tests for both the fourth and the sixth grade consist of three parts with 25 multiple choice questions each. The first module of the test was equal for all students, after which the score on the test determined whether the students took a difficult or an easier module in part two of the testing. The total number of correct answers was then transformed into a scaled achievement score, which ranges between 0 and 100.
The test was designed to give an indication of the general proficiency level in Dutch. The test tested three types of linguistic skills: Morphological, Syntactical, and Semantic (Instituut voor Toegepaste Sociologie [ITS], 1994a). The students had to evaluate whether each of the 59 sentences in the test were correct or incorrect. The internal consistency of this task was good with a Cronbach’s alpha of .77.
Decoding skill was assessed using a standardized Dutch word-reading test, the Three Minutes Test (Verhoeven, 1995). Only Card 3 of the test was administered, which has less frequent polysyllabic words of increasing difficulty. The students were required to read as many words as possible out loud in 1 min. The score was the total number of words read correctly. The internal consistency of this task was high with a Cronbach’s alpha of .90.
Nonverbal Reasoning test
Nonverbal Reasoning was measured using two subtests of a nonverbal intelligence test (ITS, 1994b): Composing Figures and Exclusion. Composing Figures involved 19 items requiring the child to identify the missing part of a figure out of four alternatives. Exclusion involved 15 items requiring the child to identify the deviant figure out of four alternatives. The internal consistency of this task was good with a Cronbach’s alpha of .77.
The CITO Calculation and Mathematics Test contain 83 items concerned with numbers, measurement and time (Janssen, Kraemer, & Noteboom, 1995). The internal consistency of the task was high with a Cronbach’s alpha of .89.
The scale consisted of eight items from the IEA Student Questionnaire (International Association for the Evaluation of Educational Achievement [IEA], 2001). The scale concerned the frequency of reading for fun outside school, reading stories, novels outside school, borrowing books from the library to read outside school, reading silently in school and the responses to the following four statements: ‘I only read if I have to’ (reverse coded), ‘I would be happy if someone gave me a book as a present’; ‘I think reading is boring’ (reverse coded), ‘I enjoy reading’. The internal consistency of this task was good with a Cronbach’s alpha of .77.
The scale consisted of five items taken from the PRIMA Questionnaire (Driessen et al., 2002): ‘I perform generally well’; ‘I am one of the best students in the class’; ‘most of the children in my class perform better than I do’ (reverse coded); ‘my teacher thinks I perform well’; ‘I don’t need a lot of help at school’. The internal consistency of this task was good with a Cronbach’s alpha of .75.
Home Reading Resources
The scale consisted of three items related to the number of books in the home, the presence of a computer and a newspaper in the home. The internal consistency of this task was high with a Cronbach’s alpha of .91.
All variables were collected in grade 4. Reading Literacy was again measured in grade 6. Trained master students administered the data. The test for word decoding was administered individually, all other tests were administered group-wise.
In order to address the first question, t-tests were conducted to test differences between predictor measures, and analysis of variance with repeated measures was undertaken to examine the development of reading literacy across grades.
To find an answer to the second question, a series of LISREL analyses (Version VIII, Jöreskog & Sörbom, 1993) was conducted to explore the relations between the children’s reading literacy and its predictors. An attempt was made to design a structural model with Nonverbal Reasoning and Home Reading Resources as background variables, Decoding, Language, Mathematics, Reading Motivation, and Academic Self-confidence as intermediate variables, and Reading Literacy in grade 4 and 6 as criterion variable. To determine whether the model predicts reading literacy results in grade 6 for both first and second language learners, and whether the strengths of the relationships between the entered variables are similar for the two subgroups, the model was tested using data for L1 and L2 learners, separately. The parameters of the model were estimated using a Maximum Likelihood procedure. The Goodness-of-fit of the proposed model was evaluated with five indicators, according to Hu and Bentler’s (1999) criteria: the ratio of the chi-square value to the degrees of freedom (less than 3), the Goodness of Fit Index (GFI > .85), the Adjusted Goodness of Fit (AGFI > .90); Normed Fit Index (NFI > .90); Root Mean Square Error of Approximation (RMSEA < .08).

As expected the best predictor for Reading Literacy in grade 6 was Reading Literacy in grade 4. Language, Mathematics, and Decoding were strong to moderate predictors for explaining the development in Reading Literacy, whereas the predictive power of Reading Motivation and Academic Self-confidence was small but significant. Furthermore, Nonverbal Reasoning was found to predict Reading Literacy, as well as the intermediate variables of Language, Mathematics, and Academic Self-confidence. Home Reading Resources contributed significantly to the prediction of Reading Literacy and the intermediate variables of Language and reading Motivation.
Home Reading Resources did not predict any of the intermediate variables or criterion variables significantly, and is not shown in the model. It can be seen that Reading Literacy in grade 4, Decoding, and Academic Self-confidence were important predictors of Reading Literacy in grade 6 whereas Language, Mathematics, and Reading Motivation significantly predicted Reading Literacy in grade 4. Furthermore, Nonverbal Reasoning predicted Reading Literacy and the intermediate variables Language, Mathematics, and Academic Self-confidence.
Conclusions and discussion
From the present study several conclusions can be drawn. First of all, the data show that first and second language learners differ in language and reading comprehension scores in the upper grades of Dutch primary schools. This result is conforming with previous studies in the Netherlands (Verhoeven, 2000; Aarnoutse et al., 2001; van Elsäcker, 2002; Droop & Verhoeven, 2003) and elsewhere (Durgunoglu & Verhoeven, 1998; Genesee, Lindholm-Leary, Saunders, & Christian, 2006; Koda, 2007). Significant differences were also found in mathematics and nonverbal reasoning skills. It can be assumed that problems in understanding school-based instruction in Dutch schools may have caused this arrear in nonverbal abilities (cf. Cummins, 2000). Another striking result is that the home reading resources of L2 learners were significantly less as compared to L1 learners. This result has been noted in other studies focusing on the home literacy environment of linguistically diverse groups of learners (de Jong & Leseman, 2001; van Elsäcker, 2002; van Diepen, 2007; Mullis et al., 2006).
Furthermore, our structural models show that the interrelationships between reading literacy, intermediate school-related abilities and motivations, and nonverbal reasoning skills are highly comparable. In both cases, more than 60% of the variance in reading literacy by the end of primary school could be explained. For both groups, a strong autoregressive relationship of reading comprehension in grades 4 and 6 was evidenced. This result conforms with the outcome of earlier studies (e.g., Droop & Verhoeven, 2003; van Elsäcker, 2002), along with a moderate prediction of decoding, language and mathematics, on the one hand, and reading motivation and academic self-confidence, on the other hand. The prediction of reading literacy from word decoding and language conforms with the simple view of reading (Gough & Tunmer, 1986; Hoover & Gough, 1990) which was also evidenced in other studies among L2 learners (Proctor, August, Carlo, & Snow, 2006; Gottardo & Mueller, 2009). The results show that students who have a positive reading motivation and high self-confidence in grade 4 show better reading literacy abilities in grade 6. These findings are consistent with the findings of previous research on the relationship between reading literacy and reading motivation (Aunola et al., 2002; Wigfield & Guthrie, 1997; Guthrie & Wigfield, 2000). Moreover, nonverbal reasoning showed to have a direct impact on reading literacy and its intermediate variables language, mathematics and self-confidence. This result is consistent with previous research which has demonstrated that intelligence is an important predictor for reading literacy (Brooks, Fulker, & DeFries, 1990; Tiu, Thompson, & Lewis, 2003), especially in the latter grades (Stanovich, Cunningham, & Feeman, 1984).
A striking difference in the two models concerned the role of home reading resources. Not only did we find a difference in the amount of resources available, but also in its predictive power. For L1 learners, home reading resources appeared to have an impact on reading literacy and on children’s language abilities and reading motivation. For the L2 learners, however, a relationship between home reading resources and criterion as well as predictor measures was generally lacking. It can tentatively be concluded that other factors, such as the socio-cultural orientation and language use within immigrant families, may have suppressed the relationship between home reading resources and children’s reading literacy skills. A similar conclusion was also arrived at in other studies focusing on the influence of home literacy environment on a child’s reading abilities (Serpell, 2001; Dickinson & Tabors, 2002; Marks, 2005).
Of course, several limitations apply to the present study. First of all, the size of the group of second language students in our study was rather small. In order to be able to arrive at more definite answers to the question of differences in the literacy development of first and second language learners larger samples are needed. Moreover, our sample of L2 learners can be considered quite heterogeneous which makes it hard to generalize the results. This is especially the case for relationships between reading literacy and variables in the socio-cultural domain (cf. Driessen, 2001). Furthermore, the operationalization of background variables can be improved in future studies by using observations instead of questionnaires. By introducing naturalistic variables in the domain of home reading resources the validity of outcomes can be enhanced (cf. Wasik, 2004).
The results of the present study show a considerable difference in reading literacy ability between first and second language learners at the end of primary school. Since school success relies partly on reading abilities, this difference has important consequences for society. When students enter primary school, or preferably even before that, the students at risk at falling behind should receive additional language instruction. Trying to prevent the gap from forming or at least to break the cycle as soon as possible. Lesaux and Siegel (2003) found in a longitudinal study that a model of early identification and intervention for second language students at risk of falling behind in grade 1 resulted in latter grades in an achievement level in reading and spelling comparable with their L1 peers. In the case of the Dutch second language students, a content-based approach could be followed with an intervention focused on vocabulary acquisition and oral language proficiency (Droop & Verhoeven, 2003). Although some research has claimed that the influence of decoding skills would be relatively more important in earlier grades and not at the end of primary education (Joshi et al., 1998), the present study suggests that decoding skills remain important throughout primary education. This is in line with previous research showing that speed of single word reading accounts for a large amount of the variance in reading comprehension ability (Perfetti, 1985). Finally, continuity between home and school experiences can be seen as critical in the context of cultural and linguistic diversity (Dickinson & Tabors, 2002). School teams should give room to parental involvement in perspective of continuity of literacy experiences. It is by bridging the gap between literary socialization in the home and literacy education at school that the motivation, engagement, and participation of students in classroom instruction can be enhanced.
