Expository text comprehension in secondary school: for which readers does knowledge of connectives contribute the most?

The present study examined whether knowledge of connectives contributes uniquely to expository text comprehension above and beyond reading fluency, general vocabulary knowledge and metacognitive knowledge. Furthermore, it was examined whether this contribution differs for readers with different language backgrounds or readers who vary in reading fluency, general vocabulary knowledge or metacognitive knowledge levels. Multilevel regression analyses revealed that knowledge of connectives explained individual differences in eighth graders' text comprehension (n = 171) on top of the variance accounted for by the control variables. Moreover, the contribution of knowledge of connectives to text comprehension depended on a reader's level of metacognitive knowledge: more metacognitive knowledge resulted in a larger association between knowledge of connectives and text comprehension. Reading fluency, vocabulary knowledge and language background did not interact with knowledge of connectives. Findings are interpreted in the context of the strategic use of connectives during expository text reading.

What is already known about this topic?

• Connectives (words such as moreover, because and although) help the reader in establishing coherence between text parts.
• In primary school, for fifth graders, knowledge of connectives has been shown to be uniquely related to English text comprehension controlling for reading fluency and general vocabulary knowledge.
• For fifth graders, the relationship between knowledge of connectives and English text comprehension was higher for English‐only students than for their peers who learned English as a second language.

What this paper adds:

• The present study found that knowledge of connectives also has a unique relation with Dutch expository text comprehension for eighth graders above and beyond reading fluency, general vocabulary knowledge and metacognitive knowledge (about text structure and reading and writing strategies).
• The relationship between knowledge of connectives and text comprehension was not moderated by reading fluency, general vocabulary knowledge and language background (monolingual versus bilingual Dutch).
• Metacognitive knowledge did impact the relationship between knowledge of connectives and text comprehension: the higher the metacognitive knowledge, the higher the association between knowledge of connectives and text comprehension.

Implications for theory, policy or practice

• Secondary school readers are assumed to benefit from knowing connectives because these words are frequent in expository texts and signal relationships that students may often not infer without the help of these devices (i.e., with the use of background knowledge). This seems to apply in particular for expository texts that are intended to convey new information and relationships to students (see also Singer & O'Connell, 2003 ).
• We found a significant interaction between knowledge of connectives and metacognitive knowledge, which seems to indicate that knowing more connectives does not help much in improving expository text comprehension when metacognitive knowledge about text structure and reading strategies is low. This result suggests that it may be wise to couple instruction on the meaning of connectives with instruction about the structure of expository texts and ways to strategically deal with these texts.
• More specifically, besides instruction on the meaning of connectives, we advise teachers in secondary school to get students to understand the importance of connectives as markers of local and global coherence in texts, and to teach them how to strategically use connectives during reading.

Lost in narrative? The effect of informative narratives on text comprehension and metacomprehension accuracy

Informative narratives are enriched expository texts that provide to-be-learned conceptual information within a storyline with the aim to foster comprehension. However, research casts doubt on such a benefit for comprehension. Additionally, it is an open question how informative narratives impact metacomprehension accuracy. The results of two experiments (N₁ = 63 and N₂ = 70 university students) showed that informative narratives were less or not at all beneficial to text comprehension compared with expository texts. Moreover, informative narratives often led to more overestimation of comprehension in terms of predictions, postdictions, and response confidence than expository texts. This seemed to be particularly true, as Experiment 2 revealed, for readers with a lower need for cognition because they were more transported into the storyline of informative narratives. The findings suggest that informative narratives prime the activation of a narrative-specific reading goal and, thus, distract readers from learning and accurately monitoring the to-be-learned conceptual information.     

Students’ genre expectations and the effects of text cohesion on reading comprehension

This study raises the question what makes school texts comprehensible by analyzing whether students’ genre expectations about literary or expository texts moderate the impact of different forms of text cohesion on reading comprehension, even when the texts are similar regarding their genre. 754 students (Grade 9) from comprehensive schools read one of four text versions with similar content, but different degrees of local and global text cohesion. The four more or less cohesive texts were introduced as literary texts (part of a story) or as expository texts (newspaper article), although the different genres were only purported and the texts contained both literary and expository passages. Reading comprehension was assessed with multiple-choice-items, semi-open, and open-ended questions. Results demonstrate that global cohesion was profitable for reading comprehension with expository expectations, but not with literary ones. Local text cohesion and both forms of cohesion in combination did not interact with students’ genre expectations and had no main effect on comprehension. When students reading skills and prior knowledge were considered, the interaction was still apparent. Moreover, students with lower levels of reading skills tended to profit especially from texts with global cohesion, whereas the readers with higher reading skills achieved equal means in reading comprehension irrespective of the degree of global text cohesion. The findings are discussed with respect to theoretical aspects of text–reader-interactions, cognitive and emotional components of genre expectations, and the composition and instruction of comprehensible school texts.     

The effect of causal diagrams on text learning

We examined the effect of studying a causal diagram on comprehension of causal relationships from an expository science text. A causal diagram is a type of visual display that explicitly represents cause-effect relationships. In Experiment 1, readers between conditions did not differ with respect to memory for main ideas, but the readers who studied the causal diagram while reading the text understood better the five causal sequences in the text even when study time was controlled. Participants in Experiment 2 studied only the causal diagram or only the text. There were no differences in memory for main ideas or the causal sequences between these groups. Results indicate that causal diagrams are not merely redundant with text and that causal diagrams affect understanding of causal relationships in the absence of a text. These findings supported the causal explication hypothesis, which states that causal diagrams improve comprehension by explicitly representing the implicit causal structure of the text in a visual format.     

A profile of causal development amongst ten-year-olds: Implications for reading and writing

Causality has been singled out by several researchers as an important factor in text comprehension and memory. The basic assumption underlying this view is that the perception of causal ties between elements in a text binds the text elements together and enables the reader to construct a coherent representation of the text in memory. Although research findings indicate that causality is a strong predictor of comprehension in narrative texts, the role that causality plays in the comprehension of expository texts has received relatively little attention. In the research reported in this article, a profile of causal development in ten-year-olds was built up on the basis of their recall of history and science texts in which the amount of causal connectivity differed. Four variables were identified and measured, namely length of recall protocols, amount of causal connections recalled from original test passages, amount of causal density and causal hierarchicalization created in the recall protocols. The results of the recall test were also compared to the subjects' English grades. The findings indicate that causal connections play an important role in expository text recall, and that subjects who have a strong causal profile also, generally, perform well in English. The research and pedagogical implications of these findings for reading and writing skills are discussed.     

Processing of expository and narrative texts by low- and high-comprehending children

The present study investigated comprehension processes and strategy use of second-grade low- and high-comprehending readers when reading expository and narrative texts for comprehension. Results from think-aloud protocols indicated that text genre affected the way the readers processed the texts. When reading narrative texts they made more text-based and knowledge-based inferences, and when reading expository texts they made more comments and asked more questions, but also made a higher number of invalid knowledge-based inferences. Furthermore, low- and high-comprehending readers did not differ in the patterns of text-processing strategies used: all readers used a variety of comprehension strategies, ranging from literal repetitions to elaborate knowledge-based inferences. There was one exception: for expository texts, low-comprehending readers generated a higher number of inaccurate elaborative and predictive inferences. Finally, the results confirmed and extended prior research by showing that low-comprehending readers can be classified either as readers who construct a limited mental representation that mainly reflects the literal meaning of the text (struggling paraphrasers), or as readers who attempt to enrich their mental representation by generating elaborative and predictive inferences (struggling elaborators). A similar dichotomy was observed for high-comprehending readers.     

What predicts adult readers’ understanding of STEM texts?

The current study examined the relations among key variables that underlie reading comprehension of expository science texts in a diverse population of adult native English readers. Using Mechanical Turk to sample a range of adult readers, the study also examined the effect of text presentation on readers’ comprehension and knowledge structure established after reading. In Study 1, ratings of situational interest, select reading background variables, and select measures of readers’ knowledge structure accounted for significant variance in comprehension. In Study 2, the knowledge structure metrics of primacy, recency, and node degree as well as several text ratings were found to be comparable across text presentation formats. Participants who read the text sentence-by-sentence obtained higher scores on measures of comprehension and provided higher ratings of situational interest than those who received the whole paragraph text at once. Knowledge structure measures for the sentence-by-sentence and paragraph formats were similar (68% overlap). We discuss implications for future research examining factors that underlie the successful comprehension of science texts.     

Effects of picture-word integration on reading visual narratives in L1 and L2

Multimodal education materials are pervasive in language learning. This study investigated the causal mechanisms of multimodal reading effects in first language (L1) and second language (L2). Seventy-five adult bilingual readers in Hong Kong read Chinese and English passages with different degrees of picture-word integration in a within-subject design. Results showed that tight text-picture integration facilitated better comprehension than independent text-picture presentation in L2, but not L1. Perceived ease and interest differentially mediated multimodal reading performance for L1 and L2 passages. Importantly, separate images in L2 passages led to poorer comprehension accuracy relative to plain text, but tended to have higher ratings of ease and interest, indicating that readers may be overconfident in their multimodal reading performance. In general, results support the notion that integration of text and pictures can moderate the process of meaning making, and these may differ depending on the language presented to a bilingual reader.     

Impact of text availability and question format on reading comprehension processes

We conducted two experiments to analyze how text availability and question format affect readers’ processes and performance on measures of expository text reading comprehension. Junior high school students read expository texts and answered both multiple choice and open-ended questions on a computer that recorded reading times and readers’ actions with Read&Answer software. The results showed that readers reread prior text segments during initial reading of the text more often when they knew that the text would be unavailable when answering questions than when they knew that the text would be available. In addition, readers made more search decisions in the text- available condition when answering open-ended questions than when answering multiple-choice questions. Regarding performance, we repeatedly found an interaction effect between availability and question format: text availability benefited the open-ended but not the multiple-choice format. We concluded that the two availability conditions are useful in assessing different discourse processes. We discuss theoretical and practical implications for the development of models of reading and new ways to assess reading literacy skills that emphasize purposeful reading.     

The Nature of the Refutation Text Effect: An Investigation of Attention Allocation

ABSTRACT

Students often hold misconceptions that conflict with scientific explanations. Research has shown that refutation texts are effective for facilitating conceptual change in these cases (Guzzetti, Snyder, Glass, & Gamas, 1993). The process through which refutation texts have their effect is not clear. The authors replicated and extended previous research investigating cognitive processes involved in the refutation text effect. Undergraduates read either a refutation or an expository text on seasonal change. Individual reading times were recorded. Participants’ conceptions were measured at pretest, posttest, and delayed posttest. Results showed that readers spent less time reading the refutation paragraph compared to the expository paragraph. The refutation text group had fewer misconceptions at posttest. These findings suggest that refutation text processing differences mirror similar findings in the attention literature, which may account for their effectiveness.     

Exploring the eye‐movement patterns as Chinese children read texts: a developmental perspective

This study was to investigate Chinese children's eye patterns while reading different text genres from a developmental perspective. Eye movements were recorded while children in the second through sixth grades read two expository texts and two narrative texts. Across passages, overall word frequency was not significantly different between the two genres. Results showed that all children had longer fixation durations for low‐frequency words. They also had longer fixation durations on content words. These results indicate that children adopted a word‐based processing strategy like skilled readers do. However, only older children's rereading times were affected by genre. Overall, eye‐movement patterns of older children reported in this study are in accordance with those of skilled Chinese readers, but younger children are more likely to be responsive to word characteristics than text level when reading a Chinese text.     

Speech and Language Difficulties in Children With and Without a Family History of Dyslexia

According to recent psychological theories of situation model construction, readers routinely and quickly construct inferences that elaborate causal antecedents of explicit events in the text, but not inferences about causal consequences. The process of forecasting lengthy causal chains into the future is taxing on working memory, so these inferences are either not constructed or their construction consumes a comparatively large amount of reading time. This study collected self-paced sentence reading times from younger and older adults who read expository texts on scientific and technological mechanisms. Readers were also measured on working memory span, general world knowledge, reasoning ability, and reading frequency. Multiple regression analyses on the reading times revealed that (a) causal consequence inferences were more time consuming than causal antecedent inferences and (b) noncausal elaborative inferences were not constructed. The pattern of beta weights for inference variables was remarkably similar for younger and older adults and was unaffected by other measures of individual differences. The process of constructing causal inferences is therefore stable and predictable across different groups of readers.

The role text structure inference skill plays for eighth graders’ expository text comprehension

The present study investigated whether text structure inference skill (i.e., the ability to infer overall text structure) has unique predictive value for expository text comprehension on top of the variance accounted for by sentence reading fluency, linguistic knowledge and metacognitive knowledge. Furthermore, it was examined whether the unique predictive value of text structure inference skill differs between monolingual and bilingual Dutch students or students who vary in reading proficiency, reading fluency or linguistic knowledge levels. One hundred fifty-one eighth graders took tests that tapped into their expository text comprehension, sentence reading fluency, linguistic knowledge, metacognitive knowledge, and text structure inference skill. Multilevel regression analyses revealed that text structure inference skill has no unique predictive value for eighth graders’ expository text comprehension controlling for reading fluency, linguistic knowledge and metacognitive knowledge. However, text structure inference skill has unique predictive value for expository text comprehension in models that do not include both knowledge of connectives and metacognitive knowledge as control variables, stressing the importance of these two cognitions for text structure inference skill. Moreover, the predictive value of text structure inference skill does not depend on readers’ language backgrounds or on their reading proficiency, reading fluency or vocabulary knowledge levels. We conclude our paper with the limitations of our study as well as the research and practical implications.     

Topicalization and the Processing of Expository Prose by Children: mediating effects of cognitive styles and content familiarity

This study assessed the effects of text topicalization conditions (initial position, final position, or no topic sentence) on the comprehension of main ideas and specific passage information for middle school readers. Also of interest were interactions of topic familiarity and readers’ cognitive styles (degree of field independence) with text topicalization. One hundred and seven subjects were randomly assigned to one of the three topicalization conditions and read three familiar and three less‐familiar multipleparagraph expository texts. Main idea comprehension was assessed with both a sentencesummary (generation) and best‐title (recognition) task. Comprehension of specific passage information was evaluated with multiple‐choice items. Text topicalization effects were observed for main idea comprehension (with initial position best, followed by final position), while topic familiarity resulted in higher comprehension scores for specific passage information. Moreover, a cognitive style‐text topicalization interaction was found on the best‐title task; in this case, relatively field dependent readers were assisted by a final topic sentence placement. Implications are drawn for future research concerning the complex interplay of texts, tasks and readers in prose‐processing.     

Do illustrations help or harm metacomprehension accuracy?

The present research examined the effect of illustrations on readers' metacomprehension accuracy for expository science text. In two experiments, students read non-illustrated texts, or the same texts illustrated with either conceptual or decorative images; were asked to judge how well they understood each text; and then took tests for each topic. Metacomprehension accuracy was computed as the intra-individual correlation between judgments and inference test performance. Results from both studies showed that the presence of decorative images can lead to poor metacomprehension accuracy. In the second study, an analysis of the cues that students reported using to make their judgments revealed that students who used comprehension-relevant cues showed more accurate metacomprehension. A self-explanation instruction did not alter either comprehension-relevant cue use or metacomprehension accuracy, although some advantages were seen when readers were prompted to self-explain from texts illustrated with conceptual images. These results suggest that students may need more explicit instruction or support to promote the use of valid cues when engaging in comprehension monitoring with illustrated text, and that seductive information such as decorative images may undermine comprehension monitoring.     

How generalization inferences are constructed in expository text comprehension

Three questions regarding adult readers’ processing of generalization inferences (conceptually broad statements that subsume several specific statements) are investigated. College students (N = 193) read expository texts containing target statements that were consistent, inconsistent, or off-topic in relation to a generalization implied by one paragraph. Reading times were faster for consistent than inconsistent statements and faster for inconsistent than off-topic statements, indicating adult readers construct generalization inferences online during initial reading of a text and that the inference they construct is relatively narrow in scope. This pattern of faster reading time for consistent sentences occurred under different reading goals, suggesting generalization inferences are a pervasive component of expository text comprehension.     

The relation of knowledge of textual integration devices to expository text comprehension under different assessment conditions

In this study we propose a theoretical construct (called rhetorical competence) that represents the ability of readers to detect, understand, and use the linguistic cues or discourse markers that texts contain. We measure one of the three postulated components of rhetorical competence (knowledge of textual integration markers), assessing whether readers correctly interpret these markers while reading. The influence of this skill on reading competence is examined in a correlational study of 185 sixth-grade pupils (aged 11–12 years) using different assessment materials (a standardized test and an academic text) and reading conditions (habitual and aided). Multiple regression analyses of the data indicate that knowledge of textual integration devices makes a significant independent contribution to expository text comprehension under most assessment conditions when the effects of working memory, prior knowledge, and word recognition skills are controlled.
