汉语分级阅读的词汇影响因素研究

文本可读性研究旨在为分级阅读文本的选取和编写提供客观、可量化的评测依据。本文选取部编版二年级、七年级和十二年级语文教材构建低、中、高三个难度等级的文本库,从词汇多样性、词频概貌、词汇密度和词汇长度四个维度考察可能影响汉语文本可读性的词汇因素。研究发现影响低难度与中、高难度文本分级的主要词汇因素为:MSTTR>常用词词频>实词数>词种数>单音节词长>词数>双音节词长>实词比,而中、高难度文本在词汇层面并无显著差异;这些词汇因素在不同长度文本中预测效力基本一致,在一定程度上表明这些词汇因素对文本难度的评测具有有效性和稳定性。     

Investigating the validity of two widely used quantitative text tools

In recent years, readability formulas have gained new prominence as a basis for selecting texts for learning and assessment. Variables that quantitative tools count (e.g., word frequency, sentence length) provide valid measures of text complexity insofar as they accurately predict representative and high-quality criteria. The longstanding consensus of text researchers has been that such criteria will measure readers’ comprehension of sample texts. This study used Bormuth’s (1969) rigorously developed criterion measure to investigate two of today’s most widely used quantitative text tools—the Lexile Framework and the Flesch–Kincaid Grade-Level formula. Correlations between the two tools’ complexity scores and Bormuth’s measured difficulties of criterion passages were only moderately high in light of the literature and new high stakes uses for such tools. These correlations declined a small amount when passages from the University grade band of use were removed. The ability of these tools to predict measured text difficulties within any single grade band below University was low. Analyses showed that word complexity made a larger contribution relative to sentence complexity when each tool’s predictors were regressed on the Bormuth criterion rather than their original criteria. When the criterion was texts’ grade band of use instead of mean cloze scores, neither tool classified texts well and errors disproportionally placed texts from higher grade bands into lower ones. Results suggest these two text tools may lack adequate validity for their current uses in educational settings.     

Word frequency and readability: Predicting the text‐level readability with a lexical‐level attribute

Assessment of text readability is important for assigning texts at the appropriate level to readers at different proficiency levels. The present research approached readability assessment from the lexical perspective of word frequencies derived from corpora assumed to reflect typical language experience. Three studies were conducted to test how the word‐level feature of word frequency can be aggregated to characterise text‐level readability. The results show that an effective use of word frequency for text readability assessment should take a range of characteristics of the distribution of words frequencies into account. For characterizing text readability, taking into account the standard deviation in addition to the mean word frequencies already significantly increases results. The best results are obtained using the mean frequencies of the words in language frequency bands or in bands obtained by agglomerative clustering of the word frequencies in the documents – though a comparison of within‐corpus and cross‐corpus results shows the limited generalizability of using high numbers of fine‐grained frequency bands. Overall, the study advances our understanding of the relationship between word frequency and text readability and provides concrete options for more effectively making use of lexical frequency information in practice.     

Beyond first grade: examining word,sentence, and discourse text factors associated with oral reading rate in informational text in second grade

Text complexity in elementary classrooms is typically measured by traditional readability tools, which rely on surface-level measures of word and sentence complexity. Theoretical and empirical work on text complexity, however, indicates that additional measures of semantics, syntax, and discourse structure may be equally important for understanding how young children process texts. This study evaluated the components of two available text analysis tools representing different generations of readability: the Lexile Framework and the Coh-Metrix Text Easability Assessor. Using multilevel modeling, informational passage readings were nested in 5133 second-grade children in 459 schools to identify text variables that predicted changes in oral reading rate. Coh-Metrix dimensions of word concreteness, referential cohesion, and deep cohesion were uniquely associated with oral reading rate after controlling for traditional readability components. A full model including both the Lexile components and three Coh-Metrix dimensions provided the best fit to the data. Results suggest that measures of semantic complexity and text cohesion are needed to improve prediction of text difficulty for young readers and better inform text selection in the early grades. Implications for policy and practice under the Common Core State Standards, which emphasize reading complex texts across the gradespan, are discussed.

     

Flipping the Coin: Towards a Double-Faced Approach to Teaching Black Literature in Secondary English Classrooms

Critiquing two approaches that English teachers use to teach Black, or African-American, literature in the secondary classroom – one that centralises races and the other that ignores it – this article proposes a hybrid approach that combines both. This double-faced approach recognises the culturally specific themes that give the text and the Black author their unique voice while also recognising commonalities that bridge the text to others – despite the race of the authors. To demonstrate the feasibility of the double-faced approach, the article concludes with an examination of three texts through the lens of this ‘race both matters and doesn’t matter’ perspective.     

Reading biographical texts: a gateway to historical disciplinary reading

We examined the response of high school students in Israel to biographical texts. Students were exposed to three sub-genres of biographical texts (a literary-biographical text, an autobiographical text and a scientific-biographical text). These texts all differ from the conceptual schema of ordinary school texts. The data were collected from 64 participants from three classes in two different public schools in Israel. The ability of students to apply historical disciplinary reading skills was evaluated for each text, with an emphasis on ‘sourcing’ and ‘corroboration’. The basic premise was that the texts the students are exposed to influence not only their level of knowledge but also their disciplinary concepts and skills.

We contend that it might be that biographical texts, and especially autobiographical and literary-biographical texts, evoked historical reading in students, and strengthened their disciplinary reading abilities.     

The influence of narrative and expository lesson text structures on knowledge structures: alternate measures of knowledge structure

This investigation applies two approaches for representing and comparing text structures as undirected network graphs to describe the influence of narrative and expository lesson texts on readers’ knowledge structure elicited as free recall. Narrative and expository lesson texts and undergraduate participants’ free recall essays (n = 90) from a study by Wolfe and Mienko (Br J Educ Psychol 77, 541–564, 2007) were reanalyzed for lexical proximity as sequential occurrence of selected important terms in the text and as actual minimum distances between these terms. The proximity data were then rendered as Pathfinder networks for analysis. Compared to human-rater benchmark measures, the convergent validity of the sequential approach (range of r = .53 to .83, median r = .70) was a little better than that of the minimum distance approach (.51 to .80, median r = .67). Further, we anticipated that the lesson text structure would be reflected in the text structure of the free recall essays, but this was not observed. On average, the essays in all three lesson conditions tended to converge on a sequential expository structure. Further, compared to the expository lesson texts, the narrative lesson text had a distinctly different influence on posttest recall essay text structures. Overall then, the sequential occurrence approach appears to provide a reasonably good, automatically derived method for representing and comparing lesson texts and participants’ essays as network graphs. If further confirmed and fully automated, there is a wide range of application of such measurement approaches for learning and research.     

Intertextual content analysis: an approach for analysing text-related discussions with regard to movability in reading and how text content is handled

Reading and discussing texts as a means for learning subject content are regular features within educational contexts. This paper presents an approach for intertextual content analysis (ICA) of such text-related discussions revealing what the participants make of the text. Thus, in contrast to many other approaches for analysing conversation that focus essentially on the interaction per se, ICA takes the text as its starting point. Drawing on the concept of text movability and systemic-functional cohesion analyses, the approach combines a reader’s perspective and a text perspective to show the participants’ reception of the text, and also what and how text content is brought into the conversation and how it is handled. In the paper, ICA is described with regard to its theoretical underpinnings, usage and utility. It is suggested that the approach provides educational researchers with an analytical tool that allows detailed ICAs of text-related classroom discussion. Findings may ultimately lead to pedagogical implications with a bearing on classroom practice.     

The shifting sands in the effects of source text summarizability on summary writing

This paper reports the effects of the properties of source texts on summarization. One hundred and fifty-seven undergraduates were asked to write summaries of one of three extended English texts of similar length and readability, but differing in other discoursal features such as lexical diversity and macro-organization. The effects of summarizability were examined from two perspectives: students’ summarization task performance and their perception of such effects as demonstrated in the post-summarization questionnaire and interviews. Source text had significant and relatively larger effects than the summarizers’ language abilities on summarization performance. These were more pronounced on Chinese than English summarization. Perceptual data were generally supportive of the performance data and further illuminated the dynamics of the summarizability of a source text and its potential effects on performance. Macro-organization, frequency of unfamiliar words, topic familiarity, length of source texts were among the most influential factors shaping text summarizability in the view of the participants. However, the effects of summarizability proved to be rather idiosyncratic. Implications of these findings are discussed in relation to source text selection when designing summarization tasks.     

Predictors of Reading Recovery book levels

The purpose of this paper is to determine whether predictor variables, selected from readability research and from teacher nomination, might be used to grade children’s early reading books. Two hundred Reading Recovery books were rated on five variables thought to represent ‘semantic’, ‘syntactic’ and ‘phonic’ features of text. The variables accounted for 83% of book level variance. In a cross‐validation exercise they were found to be stable and reliable. It is suggested that the data support the validity of the Reading Recovery book levels, and that the formula can be used by teachers to grade children’s early reading books.     

Simplifying informational text structure for struggling readers

Direct instruction of reading strategies, such as the ‘structure strategy’, is demonstrated to be effective for the development of more mature and skilled reading processes in struggling readers. This instructional intervention approach, aimed at directly improving reading ability, can be used in combination with text simplification. Text simplification is the modification of the text in order to make it more understandable or readable for target groups of readers. In this article, we discuss a theoretically-driven text simplification approach, inspired by cognitive models of reading comprehension. Differently from classical approaches to linguistic text simplification, the aim of cognitive text simplification is not simply to reduce the linguistic complexity of the text, but to improve text coherence and the structure of information in the text. This can be achieved by using rhetorical devices, like signaling or discourse markers, which specify relationships among ideas at a global level (macrostructural) and work as processing instructions for the reader, scaffolding reading comprehension. The goal of this paper is to discuss, in light of the literature, the effectiveness of these adaptations for improving struggling readers’ understanding and learning from informational texts.     

On the Concept of Energy: Eclecticism and Rationality

In the theory of heat of the first half of the nineteenth century, heat was a substance. Mayer and Joule contradicted this thesis but developed different concepts of heat. Heat was a force for Mayer and a motion for Joule. Both Mayer and Joule determined the mechanical equivalent of heat. This result was, however, justified in accordance with those concepts of heat. Mayer’s characterisation of force reappears in the very common textbook definition ‘energy cannot be created or destroyed but only transformed’ and his theory led to a phenomenological approach to energy. Joule and Thomson’s concept of heat led to a mechanistic approach to energy and to the common definition ‘energy is the capacity of doing work’. One and the same term ‘energy’ subsumed these two approaches. The problematic concept of energy, energy as a substance, appears then as a result of an eclectic development of the concept. Another approach, which appeared in the 1860s, is directly based on the mechanical equivalent of heat and can be characterized by the use of ‘principle of equivalence’ instead of ‘principle of energy conservation’. Unlike the others, this approach, which has been lost, poses no problems with the concept of energy. The problems with the energy concept as to the kind of phenomena dealt with in the present paper can, however, be overcome, as we shall see, in distinguishing between that which comes from experiments and that which is an interpretation of the experimental results within a conceptual framework.     

Comprehending coherent and incoherent texts: evidence from eye movement patterns and recall performance

The effect of text structure on the reading process and recall performance was examined. Adult readers’ eye movements were monitored when they read coherently and incoherently structured texts (N=19). Incoherence was brought about by changing the sentence order in the middle paragraphs of the two stimulus texts. Each subject read and learned one text in a coherent and the other in an incoherent form in two experimental sessions. Immediate free recall followed the reading. The eye movement data showed that during the first pass reading, i.e. initial reading of a sentence until the end of the sentence is reached, structurally incoherent text segments attracted the largest number of regressive fixations, and, hence, were given more visual attention than coherent text segments (indicated by the total duration of fixations). On the other hand, more rereadings, i.e. all fixations made after the first pass reading but before moving away from the given sentence, were devoted to text segments resolving the incoherence. Textual incoherence was further found to lead to inferior recall. However, no clear-cut correspondence between eye movement behavior and quantitative recall performance was found.

How democratic is higher education for sustainable development?

We wondered how ‘democracy’ was being used and communicated within the higher education discourse of ‘education for sustainability’, or ‘for sustainable development’ (ES/ESD). We used a philosophical hermeneutic approach to explore the sense or senses in which the concept of democracy is used within this literature and supported our analysis by incorporating text about democracy from other disciplines. We conclude from our analysis that the concept of democracy within ES/ESD texts has evolved to suggest many meanings that in their entirety do not support our shared research mission towards ES/ESD. At the pens of ES/ESD scholars, democracy may have become one of Sartori's intolerably blunted conceptual tools.     

Using Coh-Metrix to Automatically Access Discourse Coherence in EFL Learners’Writing:A Quantitative Analysis

The purpose of the present study was to use Coh-Metrix,a computational tool,to examine the relationship between discourse coherence and writing level,and analyze the coherence of high level writing and low level writing.The study uses 5 Coh-Metrix variables to analyze 40 college students’timed compositions from Chinese Learners English of Corpus(CLEC) and their corresponding readability scores.The study demonstrates that Coh-Metrix variables,number of words,words per sentences,the Flesch-Kincaid Grade Level,LSA sentence all,and argument overlap can contribute to text coherence.Findings of the study indicate:there is a relationship between discourse coherence and writing level,but there is no significant difference between high level group and low level group in discourse coherence(p=.409>.05),and writing level can not distinguish discourse coherence in EFL learners’writing.     

Reading the Multimodal Ologies: New Literacy Challenges or Old Wine in New Bottles?

In this article, the Ologies series of books are interrogated with a focus on whether they present new challenges for the reader or merely require previously acquired skills. The multimodal texts are unusual in that they combine non-fiction with fantasy while including tactile elements such as flaps, pull-outs and items to stroke. Ways of approaching multimodal texts are discussed with reference to the work of Kress, van Leeuwen and Moss. Finally, reference is made to Mackey’s research on multimodal platforms, applying her terms ‘playing the text’, the notion of ‘performance’ and ‘engaging in the rules of the game’. The conclusion leaves the question posed in the title open and suggests further research into actual readers will reveal more.     

Accessing elaborations on core information in a hypermedia environment

Strategies for managing information in a hypermedia learning environment require the text to carry indicators that describe the presence and type of additional information available from a specific point on a computer text screen. The purpose of this study was to examine the effects of link display strategy and link density on ease of use and measures of interaction. Independent variables were link strategy (three levels) and link density (two levels), yielding six treatment groups (n = 108). Within-subjects variables were time interval and type of elaboration accessed. Dependent measures were time spent on elaborations, number of elaborations accessed, and ease of use. Primary findings were that indicating all elaborations by common link indicators in the text reduced readability and led to more extensive and random browsing behavior in users; that indicating elaborations by destination-specific link indicators in the text reduced readability and increased users' tendency to target specific elaborations; and that locating link indicators in submenus increased ratings on ease of use but drastically reduced the number of elaborations accessed and time spent reading elaborations. These findings lead to the conclusion that hypermedia designers will have to make choices between promoting exploration and reducing screen readability.     

A study of readability of texts in Bangla through machine learning approaches

In this work, we have investigated text readability in Bangla language. Text readability is an indicator of the suitability of a given document with respect to a target reader group. Therefore, text readability has huge impact on educational content preparation. The advances in the field of natural language processing have enabled the automatic identification of reading difficulty of texts and contributed in the design and development of suitable educational materials. In spite of the fact that, Bangla is one of the major languages in India and the official language of Bangladesh, the research of text readability in Bangla is still in its nascent stage. In this paper, we have presented computational models to determine the readability of Bangla text documents based on syntactic properties. Since Bangla is a digital resource poor language, therefore, we were required to develop a novel dataset suitable for automatic identification of text properties. Our initial experiments have shown that existing English readability metrics are inapplicable for Bangla. Accordingly, we have proceeded towards new models for analyzing text readability in Bangla. We have considered language specific syntactic features of Bangla text in this work. We have identified major structural contributors responsible for text comprehensibility and subsequently developed readability models for Bangla texts. We have used different machine-learning methods such as regression, support vector machines (SVM) and support vector regression (SVR) to achieve our aim. The performance of the individual models has been compared against one another. We have conducted detailed user survey for data preparation, identification of important structural parameters of texts and validation of our proposed models. The work posses further implications in the field of educational research and in matching text to readers.
