Testing the KAPS Model of Reading Comprehension in a Turkish Elementary School Context from Low Socioeconomic Background

This correlational study aimed to explore the relations of background knowledge, automaticity (rate), prosody, and strategy use with reading comprehension (KAPS model of reading comprehension) in the written Turkish language context with 207 fourth grade students. Successful comprehension requires readers to make meaning out of what they read. Our KAPS model of reading comprehension hypothesizes relations of background knowledge, fluency components (rate and prosody), and strategy use with reading comprehension components (literal and deep) in the Turkish language and addresses the direct effects of these predictors on the reading comprehension of fourth grade students. The results showed that, whereas fluency and strategy use made statistically significant contributions to reading comprehension, background knowledge did not. Based on the results, the study affirms the importance of automaticity in word recognition, prosody, and comprehension strategies in contributing to reading comprehension in Turkish and, as such, should be given priority for literacy instruction in Turkish.


Introduction
Reading comprehension, in any language, is the cognitive process of simultaneously extracting and constructing meaning through interaction and involvement with written texts [1][2][3]. Reading comprehension is often viewed as a binary capability involving literal and inferential comprehension outcomes. While literal comprehension is related to readers retrieving explicit information directly from a text [4,5], inferential comprehension involves the readers' consideration of content beyond the text and requires readers to integrate their perspectives with that of the text author. As such, inferential comprehension is theorized to be the result of analyzing and synthesizing knowledge from different sources [5][6][7].
Beyond the two levels of comprehension, reading comprehension is a complex process that is affected by a variety of cognitive factors, such as reading fluency, purposes for reading, usage of comprehension strategies, vocabulary knowledge, and background knowledge. Additional contributors to comprehension include readers' knowledge of printed language structure and language conventions through which information is conveyed [1,[8][9][10][11]].

Research Design
This research is a correlational study where we sought to understand what kind of relations reading fluency, background knowledge, and strategy use have with reading comprehension. Through this design, we aimed to clarify the hypothesized the KAPS model of reading comprehension in a Turkish. Therefore, structural equation modeling (SEM) was employed for the analysis. The reason why we used SEM is that structural equation modeling, which is a statistical technique, is used to measure underlying hypothetical constructs and their interrelationships.

Participants
The purpose of the study was to explore the relationships of background knowledge, reading fluency, and strategy use with reading comprehension in Turkish elementary-grade students. A total of 207 fourth graders from five different classes in the same school were enrolled in the study. The research took place in fall and spring semesters, 2016, in Turkey's Denizli province. The participants were willing and available to take part and informed consent letters were obtained from all of the participants and all parents or guardians. The subjects were relatively homogenous, of middle socioeconomic (SES) status, and ranged in age from 9 through 10 years. Seventy-eight girls and 119 boys who participated in the study were not identified as learning disabled and their reading development was felt to be within grade level expectations according to their classroom teachers and the school counselor. All of the students were considered typically developing readers by their teachers.

Texts
The students read an expository text that consisted of 338 words. Assessments of literal and deep comprehension, background knowledge, and fluency (both automaticity and prosody) were based on students' reading of this text. The text, which was about cartoons, was obtained from a grade appropriate Turkish language arts course textbook. The text explained the nature of cartoons, their historical development, types of cartoons, and the role of cartoons in communication. The other short passages for assessing strategy use were obtained from the same fourth grade textbook and were either reorganized or shortened for the reading strategies.

Reading Fluency
Reading fluency, including word recognition automaticity and prosody, was assessed using the expository text. Automaticity was determined by calculating the number of words read correctly in the initial 60 seconds of oral reading. Prosody was assessed qualitatively by a researcher who listened to each student read the grade-level passage and rated the prosodic quality of the oral reading using a rubric that describes levels of competency on various elements of prosody (expression/volume, phrasing, smoothness, and pace). The rubric was developed by Rasinski [36] and adapted by Yildiz, Yildirim, Ates, and Cetinkaya [37] for use with Turkish students. Prior research using the rubric with English readers has demonstrated the rubric to be a reliable and valid measure of prosody [38,39]. The Turkish adaptation of the scale included the same four main dimensions in previous studies [36]. Students' scores for the full prosody assessment ranged from a minimum of 4 and a maximum of 16.

Background Knowledge
The researchers developed a 10-item, multiple-choice test to assess the students' background knowledge about cartoons, the content in the main text. The researchers examined the text to identify content (knowledge) that was judged to be essential for correctly answering the questions. Distractors in the background knowledge test included either facts that were presented in the text or events that were judged to be familiar from participants' everyday experiences but not consistent with the information presented in the text. The test-retest reliability of the prior knowledge measure was computed, with 3 weeks between the test and the retest. A The reliability estimate was determined to be (Pearson r) 0.81 (see Appendix A).

Reading Comprehension Strategies
Strategy use was determined using a 12-item, researcher-developed measure that was based on work by Kozminsky and Kozminsky [40] and was also similar to the measures employed in previous research [41,42]. Short passages, appropriate for fourth grade, were identified from fourth grade Turkish language arts textbooks. After reading each passage, the students answered two multiple-choice items that required the use of various reading comprehension strategies. For example, for the strategy of summarizing, students read a passage and were presented with four possible summary sentences. Their task was to choose the best summary of the passage. Based on the findings from previous research relevant to strategy instruction, we identified and assessed six strategies: activating background knowledge, summarizing, identifying main idea, awareness of text structure, predicting, and self-questioning (see Appendix B).

Reading Comprehension
Following previous research [43], we developed a sentence verification task (SVT) to measure the students' literal comprehension of the main text (Cronbach's Alpha = 0.71). The SVT was developed by generating four types of test items from sentences in the text/s: (a) originals, which were copies of sentences that appeared in the text/s; (b) paraphrases, which were constructed by changing as many words as possible in original sentences without altering the essential meaning; (c) meaning changes, which were constructed by changing one or two words in original sentences so that the meaning of the sentences was altered; and (d) distractors, which were syntactically similar and thematically related to the original sentences but were not consistent with the meaning to the originals. The test consisted of 16 items (four originals, four paraphrases, four meaning changes, and four distractors) that the participants were asked to mark "yes" for items that had the same meaning as text sentences (originals or paraphrases) or "no" for those that had a different meaning (meaning changes and distractors).
Again, following Royer et al. [43] and Strømsø, Bråten, and Samuelstuen [44], we constructed an inference verification task (IVT) to measure the students' deeper or inferential, understanding of the same text (Cronbach's Alpha = 0.67). This test consisted of 16 items, 8 of which were near inference items and 8 of which were far inference items. The near inference items were constructed by combining information in the text to form either a valid or invalid inference. The far inference items were constructed by combining an item of information from the text with information that the student would likely have about the topic in order to create valid or invalid inference. The students were instructed to mark "yes" for the items that could be inferred from material presented in the text, and "no" for those that could not be inferred from material presented in the text (see Appendix C).

Procedure
Prior to the study, the main text, short passages and accompanying questions were reviewed by experts in reading education from a public university in Turkey. All reviewers had Ph.D. degrees in elementary school education. The experts reviewed the extent to which the texts adequately corresponded to reading domain objectives of the fourth grade Turkish language arts curriculum and the extent to which the questions adequately measured comprehension of the texts. The experts also verified that each comprehension question was appropriate given developmental standards and the students' reading levels.
Students initially completed the multiple-choice background knowledge test. Next, they were asked to read the grade-appropriate expository text on cartoons and complete the SVT and IVT tests. Students were tested individually and asked to orally read the passage corresponding to their grade level placement. The students were asked to read the text in their best or most expressive (prosodic) voice and were told that they would be questioned about what they had read following their reading. During each student's oral reading, the researcher administering the test marked any uncorrected word recognition errors made by the student as well as marking the text position of the student at the end of 60 seconds in order to determine reading rate, a measure of word recognition automaticity. Prosody, or expressive reading, the second element of fluency, was measured by independent evaluators listening to the student reading and then rating the prosodic quality of the oral reading using the Turkish adaptation of the multi-dimensional fluency rubric [45].

Results
The data obtained from the students' readings included measures of literal and inferential comprehension, word recognition automaticity (words read correctly per minute), prosody (qualitative rating of expressiveness using the multi-dimensional fluency scale), background knowledge, and strategy emloyment. Means and standard deviations for the six variables are presented in Table 1. The relationship between the comprehension related factors and comprehension itself, was determined by calculating correlations between variables. The correlations are presented in Table 2; all correlations were found to be statistically significant and substantive. Given the positive and significant correlations among the variables in Table 2, we ran a path analysis using AMOS and Mplus statistical modeling programs. By this analysis, we aimed to determine the relations among the variables in an integrated model of reading comprehension. Those results are presented in the path diagram in Figure 1.
In the path analysis model, fluency, comprehension strategies, and background knowledge were used to predict reading comprehension. The path analysis results revealed that RMSEA, SRMR, TLI, and CFI values were within expected ranges. The fit of the data, then, to the proposed path model was considered good. For the full sample, the model yielded good fit indices. When reviewing overall fit summary indices in the model, the χ2 test yielded a value of 5.752, which was evaluated with 5 degrees of freedom, and had a corresponding p-value of 0.331. The χ2/df was 1.150. Additionally, the RMSA was 0.027. The TLI was 0.99 and CFI was 0.99. Moreover, SRMR was 0.0132. These fit measures suggest that all of the indices expressed in the path analysis were a good fit to the data [46,47]. In the model, fluency and comprehension strategies made statistically significant contributions to the prediction of reading comprehension (β = 0.46, p < 0.001 and β = 0.27, p < 0.01, respectively). Background knowledge, however, did not make a statistically significant contribution to the prediction of reading comprehension (β = 0.13, p > 0.05). Overall, this model explained 45% of the variance in reading comprehension. Having a relatively high R-squared value in these predictions indicates that this model works well in the Turkish language context.

Discussion
In the current study, we aimed to explore the validity of the KAPS model in the Turkish language context with Turkish elementary students by determining the direct relationships between fluency, background knowledge, and strategy usage as they contribute to comprehension. All contributors to comprehension, except for background knowledge, were found to be components of the model for reading comprehension.
A successful comprehension process requires the reader to make meaning. Previous research has shown that comprehension requires readers to employ prior knowledge and integrate it into text processing [20]. Additionally, comprehension occurs when readers connect their prior knowledge to the text, make connections between different parts of the text, and make connections between known and unknown information [11]. While previous research has shown that there are profound positive relations between prior knowledge and reading comprehension [21,22,26], the results suggest that, in a more complex model of comprehension, there was no significant relationship between reading background knowledge and reading comprehension. Students' ackground did not contribute

A successful comprehension process requires the reader to make meaning. Previous research has shown that comprehension requires readers to employ prior knowledge and integrate it into text processing [20]. Additionally, comprehension occurs when readers connect their prior knowledge to the text, make connections between different parts of the text, and make connections between known and unknown information [11]. While previous research has shown that there are profound positive relations between prior knowledge and reading comprehension [21,22,26], the results suggest that, in a more complex model of comprehension, there was no significant relationship between reading background knowledge and reading comprehension. Students' ackground did not contribute significantly to the prediction of reading comprehension in the path analysis model. This result was not consistent with the previous research findings. In as much as previous research has verified the importance of background knowledge, the lack of a significant contribution of this variable in the current study may have been due to the use of an assessment of background knowledge that insufficiently assessed students' knowledge. Future research of models of reading in Turkish need to consider more robust measures of students' background knowledge.
The other result of the present study suggests a strong relation between reading strategy use, fluency, and comprehension. Fluent and proficient readers know how to and when to use reading comprehension strategies when they read. In other words, fluent readers are able to effectively use reading strategies during reading. This enables them to monitor reading comprehension processes [48,49]. The students' scores of strategy use made statistically significant and substantial contributions to reading compression. This result was consistent with the previous research [10,31,50]. Mariotti [10] has found that vocabulary and strategy use were significant components of reading comprehension. Moreover, Seipel et al. [31] reported that proficient readers are better in strategy use compared to poor readers. Additionally, Reed and Lynn [44] found that using comprehension strategies such as making inferences from the text to be read had significant effects on reading comprehension.
The results of this study affirm the significance of fluency (including both automaticity in word recognition and prosody) as a significant variable in proficient reading and reading comprehension [9,18,[51][52][53][54][55] in Turkish fourth grade students. As such, continued instruction in reading fluency, automaticity, and prosody, for Turkish students beyond third grade is warranted. Additionally, instruction in the application of specific comprehension strategies can also be recommended. Comprehension is not a passive task, and the use of comprehension strategies ensures that readers will actively monitor and process meaning as they read. Thus, comprehension strategies, especially the ones tested in the present study, and reading fluency (automaticity and prosody) need to be given priority for literacy instruction for Turkish elementary students, at least through Grade 4, and perhaps beyond for struggling readers.
In conclusion, while the current study could not validate the complete hypothesized KAPS model of reading comprehension in Turkish language, it adds to the accumulating evidence of the importance of reading fluency and comprehension strategies for proficient reading, especially among upper elementary school students.
