说明文阅读中因果序列的表征

结合自定步调阅读与句子启动再认范式, 探讨说明文阅读过程中因果序列的表征问题。研究包括3个实验, 实验1的文本提供一个包括4个概念的因果链(如, A－B－C－D), 文本最后设置包含概念A或概念B或概念C的句子, 对概念D进行探测, 结果发现, 对于概念D的再认启动作用, 概念C＞概念B＞概念A; 实验2改变因果链的说明顺序, 使之与因果链本身次序不一致, 结果与实验1一致; 实验3的文本分别介绍两条独立的因果链(如A－B－C; D－E－F), 最后呈现包含概念A或概念D的句子, 对概念C进行探测, 结果发现, 包含概念A的句子理解启动了相关因果链, 使读者对随后呈现的概念C的再认反应加快。基于本研究结果, 结合相关研究, 本文尝试提出说明文文本表征的建构模式。     

Comprehending Expository Texts: The Role of Cognitive and Motivational Factors

This study explored the differential contribution of cognitive and motivational factors on the comprehension of an expository text in secondary school students. One hundred and fifty-five 7^th and 8^th grade students were assessed in prior knowledge, inferences, metacognition, reading motivation, topic interest, and reading comprehension of history text. According to the multiple regression analyses, inferences and self-efficacy uniquely contributed to reading comprehension. Intrinsic motivation moderated the association between metacognition and reading comprehension of a history text. These results confirm that the final outcome of reading comprehension greatly depends on a complex interplay between cognitive and motivational variables.     

熟悉主题说明文阅读推理加工的认知神经机制

采用功能磁共振成像(Functional Magnetic Resonance Imaging, fMRI)技术对熟悉主题说明文阅读过程因果推理加工进行研究, 探讨说明文阅读过程中读者是否能够自发进行因果推理加工, 以及阅读焦点的存在是否会对说明文阅读过程中的因果推理加工产生影响。结果表明, 读者在熟悉主题说明文阅读过程中能够自动进行推理加工, 负责推理加工的主要脑区为额叶(尤其是额下回)、顶叶下部及双侧楔前叶等区域。在熟悉主题说明文阅读过程中, 阅读焦点的存在一定程度上使读者的认知加工资源集中在对与焦点相关的推理关系的加工上。     

The Relationship between Oral Narrative Production and Expository Text Comprehension of Fifth-Grade Students

The purpose of the present study is to determine if there is a relationship between oral narrative production and the reading comprehension of expository text. The researcher measured both overall and component scores for expository text comprehension and oral narrative production ability of 40 typically-developing fifth grade students. Findings included a moderate correlation between overall expository comprehension and oral narrative production. A significant linear regression indicated that oral narrative production and background knowledge accounted for 18.9% of the variance in expository comprehension. Lastly, significant differences were found in the means of overall oral narrative production, narrative elements, and oral narrative in the single-scene picture condition between the low and high comprehension groups. An implication of this research is that classroom teachers could explore using an oral narrative-based intervention to improve the expository text comprehension of their fifth-grade students.     

The Effects of Familiarization with Oral Expository Text on Listening and Reading Comprehension Levels

This study examined the effects of text type and early familiarization with oral expository text structures on listening and reading comprehension levels. Second-grade students read and listened to narrative and expository texts, and their comprehension was assessed with a sentence verification task. Half of the students had participated in a nine-week long intervention designed to familiarize them with oral expository structures in the previous year while in first grade. The findings indicated that familiarization did not lead to the expected advantage of listening over reading for either expository or narrative text. Implications concerning the conceptualization of comprehension as a unitary process construct are discussed.     

Levels of Reading Comprehension Across Text Types: A Comparison of Literal and Inferential Comprehension of Expository and Narrative Texts in Iranian EFL Learners

The purpose of this study was to investigate two levels of reading comprehension, namely literal and inferential, of two text types of narration and exposition in Iranian EFL learners. The elicitation instruments were four expository texts and four narrative ones. One hundred eighty upper-intermediate EFL learners were assigned the reading passages followed by both literal and inferential multiple-choice items. Paired-samples t tests were run to provide answers to the research questions of this study. From an inter-text-type angle, the results demonstrated that the participants meaningfully outperformed on the expository texts at the level of literal comprehension. Yet, regarding inferential comprehension, there was no significant difference between the two text types. The results, from an intra-text-type perspective, also revealed that in the expository texts, literal comprehension meaningfully outweighed inferential comprehension, whereas no significant difference was observed between literal and inferential comprehension in the narrative texts. Finally, probable explanations and interpretations for the obtained results were provided.     

THE RELATIONSHIP BETWEEN LISTENING AND READING COMPREHENSION OF DIFFERENT TYPES OF TEXT AT INCREASING GRADE LEVELS

This study examined the hypotheses that (a) the relationship between listening and reading comprehension becomes stronger after decoding mastery; (b) the difference between listening and reading decreases with increasing grade level; and (c) similar patterns of relationship and difference are obtained with narrative and expository texts. The sample included 612 students in Grades 2, 4, 6, and 8. Students read and listened to two narratives and two expository texts and completed corresponding comprehension tests that were in the form of sentence verification tasks. The findings confirmed the first two hypotheses but not the third one. In the case of expository text, the relationship between listening and reading comprehension was weaker than the corresponding one with narrative text, and performance levels were comparable across all elementary grades. Moreover, reading comprehension levels were higher than listening comprehension levels in Grade 8, regardless of text type. The implications of these findings with respect to the dominant unitary process model and the assessment and instruction of oral and written language comprehension are discussed.     

Reading Comprehension in Aging: The Role of Working Memory and Metacomprehension

This study examines age-related differences in reading comprehension analyzing the role of working memory and metacomprehension components in a sample of young (18–30 years), young-old (65–74 years), and old-old (75–85 years) participants. Text comprehension abilities were measured by a standardized test, including two texts: a narrative and an expository text. The elderly's reading comprehension performance, when compared to the norm, emerged to be adequate. More specifically, the young-old showed an equivalent level of comprehension as the young adults for the narrative text. However, a clear age-related decline was found in the case of the expository text. Hierarchical regression analyses showed that working memory capacity, as well as different metacomprehension components but not age, are the key aspects in explaining the different patterns of changes in the comprehension of narrative and expository texts.

Expository Texts in First-Grade Classroom Libraries: Issues in Teacher Selection

Abstract

In 2010, the Common Core State Standards (CCSS) were adopted by most states in the US. The authors of these standards called for a shift from previous standards by recommending that young children experience a 50-50 balance between informational and literary reading. For this mixed-methods study, researchers examined the contents of 23 first-grade classroom libraries 8?years after the implementation of the CCSS to determine the percentage of expository texts found in these libraries and if these percentages differed based on the SES of the school or the number of years a teacher had been teaching. In addition, researchers interviewed twelve selected classroom teachers to gain an understanding of how they selected books for their libraries and what influenced their decisions. Results indicated that 22.8% of the texts found in first-grade classroom libraries were expository and there was no difference based on SES of the school or years a teacher had been in the classroom. Teacher interviews indicated that book cost, reading level, student interest, and genre (both narrative and expository/nonfiction) influenced their library text selections. Only two teachers indicated that the CCSS impacted their book choices.     

Vocabulary Self-Selection: A Study of Middle-School Students' Word Selections from Expository Texts

This study investigated students' decision-making as they self-selected important words from expository texts. Participants were 94 eighth graders and six adult readers. Data sources included students' written responses containing their word selections and reasons for selecting words from eight informational passages, student interviews, and word selections of adult readers. We examined the students' reasons for their word selections and compared their words with those selected by adult readers. Results indicated the following: 1) students of varying reading abilities can self-select important words in an expository passage; 2) students' reasons for selecting words differed from reasons found in related studies; and 3) variability exists across individual students and across adult readers in selecting important words in expository passages.     

The Effects of Text Difficulty on Second Graders' Fluency Development

In this study, two groups of second graders participated in Fluency-Oriented Reading Instruction (FORI) but their repeated reading experiences used different kinds of texts. One group—the Literature group—read texts from the district's literature-based, basal reading program. The second group—the Content group—read from a set of science and social studies texts that were written to have few rare, multisyllabic, single-appearing words. Control-group students read from the district's literature-based program. Both intervention groups made greater gains in reading rate than Control group students and Content students made greater gains in reading rate than Literature students. Content and Literature groups outperformed Control students on the comprehension measure but did not perform significantly differently from one another. The gains made by the Content classrooms were made in approximately half the amount of time allocated to reading instruction as by Literature classrooms.     

ETAT: Expository Text Analysis Tool

Qualitative methods that analyze the coherence of expository texts not only are time consuming, but also present challenges in collecting data on coding reliability. We describe software that analyzes expository texts more rapidly and produces a notable level of objectivity ETAT (Expository Text Analysis Tool) analyzes the coherence of expository texts. ETAT adopts a symbolic representational system, known asconceptual graph structures. ETAT follows three steps: segmentation of a text into nodes, classification of the unidentified nodes, and linking the nodes with relational arcs. ETAT automatically constructs a graph in the form of nodes and their interrelationships, along with various attendant statistics and information about noninterrelated, isolated nodes. ETAT was developed in Java, so it is compatible with virtually all computer systems.     

Influence of Question Format and Text Availability on the Assessment of Expository Text Comprehension

This study examines how passage availability and reading comprehension question format (open-ended vs. multiple-choice) influence question answering. In two experiments, college undergraduates read an expository passage and answered open-ended and multiple-choice versions of text-based, local, and global bridging inference questions. Half the participants were allowed to refer to the passage when answering the questions and half were not. Participants' prior domain knowledge relating to the text contents was assessed using multiple-choice and open-ended questions. Correlation-based analyses in the two experiments indicated: (a) a decline in the relationship between prior domain knowledge and comprehension when the passage was available during question answering; and (b) a high correlation between multiple-choice and open-ended question answering performance when the passage was not available for reference. Overall the results indicate that the nature of the reading comprehension assessment is influenced by the specific task with which comprehension is assessed.

Text Comprehension Training for Disabled Readers: An Evaluation of Reciprocal Teaching and Text Analysis Training Programs

Forty-six reading disabled adolescents were randomly assigned to one of three 25-hr instructional programs. Two programs provided training in expository text comprehension, and a third offered training in academic problem solving and organizational and study skills (an alternative treatment control). One reading comprehension program was designed to remediate a deficient knowledge base, forcing disabled readers to elaborate and further process new text knowledge, focusing on both specific informational content in a text and knowledge of text structure per se. The second program was patterned after the Palincsar and Brown (1984) reciprocal teaching techniques and focused on training four text comprehension strategies used by skilled comprehenders. Both the “knowledge-base” and the “strategy” training approaches were associated with significant improvement in disabled readers' comprehension skills, although training effects did not generalize across all aspects of reading comprehension performance. Strategy-trained readers applied the trained strategies with equal success on instructed and uninstructed text materials, providing strong evidence of transfer of learning. Knowledge-base readers also demonstrated successful transfer of specifically trained procedures (semantic mapping, text analysis) to unfamiliar text. In both programs, the best outcomes were obtained when specific strategies and operations were targeted for training.     

Can reading time predict mind wandering in expository text?

Prior research has suggested that episodes of mind wandering not only negatively impact text comprehension but also are associated with fluctuations in reading behavior. However, these studies typically do not account for differences in the fundamental nature of the text itself, namely, whether it is narrative or expository in structure. As much research has supported the idea that these text genres are processed differently, it is of interest to determine whether similar changes in reading patterns are observed when mind wandering in an expository text. The present study examined whether fluctuations in sentence‐by‐sentence reading times were associated with periods of mindless reading during processing of an expository text. Results indicated that although mindless reading did negatively impact learning, probed reading time did not vary as a function of mind wandering. These results suggest that research aimed at studying mind wandering while reading may need to account for text genre.     

Depending on My Mood: Mood-Driven Influences on Text Comprehension

Reading comprehension is a critical component of success in educational settings. To date, research on text processing in educational and cognitive psychological domains has focused predominantly on cognitive influences on comprehension, and in particular, those influences that might be derived from particular tasks or strategies. However, there is growing interest in documenting the influences of emotional factors on the processes and products of text comprehension, because these factors are less likely to be associated with explicit reading strategies. The present study examines this issue by evaluating the degree to which mood can influence readers' processing of text. Participants in control, happy-induced, or sad-induced groups thought aloud while reading expository texts. Happy, sad, and neutral moods influenced the degree to which readers engaged in particular types of coherence-building processes in the service of comprehension. Although reading strategies clearly influence processing, understudied factors that are less explicitly goal-driven, such as mood, can similarly impact comprehension activity. These findings have important implications for the role of mood on reading instruction and evaluation.     

First and Fourth Grade Boys' and Girls' Preferences For and Perceptions About Narrative and Expository Text

This investigation focused on elementary-aged (first and fourth grade) children's individual preferences for narrative and expository text and perceptions of what their same-aged peers would like to read. Preferences and perceptions of text were examined through the lenses of social constructivist and engaged reading theories. The overall purpose of this study was to examine elementary students' preferences for and perceptions about narrative and expository text. This study was a systematic replication and extension of Chapman, Filipenko, McTavish, and Shapiro's (2007) research in British Columbia with first graders. Two individually administered book preference (Open and Closed) tasks and interviews were administered to 84 students. Findings revealed gender and grade level profiles in terms of preferences, perceptions, and rationales for their book choices. As expected, both first and fourth grade boys demonstrated a strong preference for expository text, however, the fourth grade boys also showed a growing preference for narrative text as well. In contrast, both first and fourth grade girls demonstrated a strong preference for both narrative and expository text. For both boys and girls, book topic and pictures/illustrations were the two top categories that drew the children's interest and resulted in the most conversations. Results are discussed in light of implications for instruction, assessment, and future research.
