Language comprehension is crucial to reading. However, theoretical models and recent research raise questions about what constitutes this multifaceted domain. We present two related studies examining the dimensionality of language comprehension and relations to reading comprehension in the upper elementary grades. Studies 1 (Grade 6; N = 148) and 2 (Grade 3–5; N = 311) contrasted factor models of language comprehension using item level indicators of morphological awareness and vocabulary (Studies 1 and 2) and syntactic awareness (Study 2). In both studies, a bifactor model—including general language comprehension and specific factors for each language component—best fit the data, and general language comprehension was the strongest predictor of reading comprehension. In Study 2, the morphology-specific factor also uniquely predicted reading comprehension above and beyond general language comprehension. Results suggest the value of modeling the common proficiency underlying performance on tasks designed to tap theoretically distinct language comprehension skills.  相似文献

This article used the Wald test to evaluate the item‐level fit of a saturated cognitive diagnosis model (CDM) relative to the fits of the reduced models it subsumes. A simulation study was carried out to examine the Type I error and power of the Wald test in the context of the G‐DINA model. Results show that when the sample size is small and a larger number of attributes are required, the Type I error rate of the Wald test for the DINA and DINO models can be higher than the nominal significance levels, while the Type I error rate of the A‐CDM is closer to the nominal significance levels. However, with larger sample sizes, the Type I error rates for the three models are closer to the nominal significance levels. In addition, the Wald test has excellent statistical power to detect when the true underlying model is none of the reduced models examined even for relatively small sample sizes. The performance of the Wald test was also examined with real data. With an increasing number of CDMs from which to choose, this article provides an important contribution toward advancing the use of CDMs in practical educational settings.  相似文献

This article reports an investigation of some of the skills needed for the critical reading of physics texts. To assess these skills a reading comprehension test was developed that combines features of errordetection and true–false–unreported tests. This test was administered to college students of physics, and the results were analyzed statistically to determine the separability of the skills and their hierarchical ranking. It was found that the skill required to comprehend texts in continuous format is of a higher level than and separable from the skill required to comprehend texts in the form of a separated list of statements. The skill required to discriminate unreported statements from the others (true and false) was found to be of a higher level than and separable from the skills required to make the other discriminations. The relation between the students' reading comprehension skills and their problem-solving ability was also investigated. Students' scores on reading comprehension of texts that require a very low problem-solving ability were found to be uncorrelated to their grades on solving problems that require a very low decoding ability. This implies that the two abilities are independent.  相似文献

Two experiments were conducted to test the hypothesis that sentence processing is an essential mediatory skill between word recognition and text comprehension in reading. In Experiment 1, a semantic similarity judgement task was used with children from Grade 2 to Grade 9. They had to say whether two written sentences had the same (or very similar) meanings or whether the meanings of the two sentences were very different. As expected, performance improved with age both on the high‐frequency words and with increasingly complex sentences. In Experiment 2 with children in Grade 3, scores in written sentence comprehension and vocabulary made the most important unique contribution to the reading comprehension of an expository text. The results are discussed first, in the light of a general framework in which sentence‐level skill is at the core of reading comprehension and second, with reference to the issue of reading assessment.  相似文献

近年来关于DINA模型的相关研究显示,样本量、先验分布、经验贝叶斯或完全贝叶斯估计方法、样本的代表性、项目功能差异和Q阵误指等,均可能是导致DINA项目参数估计发生偏差的原因。使用Monte Carlo模拟试验,对DINA项目参数(猜测参数和失误参数)的组合变化类型和偏差量进行考察,通过条件极大似然估计法估计知识状态,发现项目参数估计值与真值偏差不大时,对知识状态估计的精度影响不大;但是项目参数偏离真值较大时,尤其是在三种组合类型上,对属性掌握存在明显的高估或低估现象。研究结果对于诊断测验等值有一定的启示:若两个测验上锚题的项目参数出现了较大的偏差(0.1),则需要考虑等值的必要性。  相似文献

本研究应用项目反应理论,从被试的阅读能力值和题目的难度值这两个方面,分析阅读理解测试中多项选择题命题者对考试效度的影响。实验设计中,将两组被试同时施测于一项“阅读水平测试”,根据测试结果估计出的两组被试能力值之间无显著性差异。再次将这两组被试分别施测于两位不同命题者所命制的题目,尽管这些题目均产生于相同的阅读材料,且题目的难度值之间并没有显著性差异,被试的表现却显著不同。Rasch模型认为,被试表现由被试能力和试题难度共同决定。因此,可以推测,这是由于不同命题者所命制的题目影响了被试的表现,并进而影响了使用多项选择题进行阅读理解测试的效度。  相似文献

The present study examined whether specific item characteristics, such as mode of acquisition (MoA) of word meanings, make reading comprehension tests particularly difficult for deaf children. Reading comprehension data on nearly 13,000 hearing 7-to-12-year-olds and 253 deaf 7-to-20-year-olds were analyzed, divided across test levels from second to sixth grade (not necessarily corresponding to chronological age). Factor analyses across item scores suggested that, of the determinants studied, MoA--referring to the type of information (perceptual, linguistic, or both) used in word meaning acquisition--was the only factor that contributed significantly to deaf and hearing children's reading comprehension. For hearing children, MoA influenced item scores at the third- and fourth-grade levels. For the deaf children, MoA influenced item scores through the sixth-grade level.  相似文献

ABSTRACT

Reading comprehension is a crucial skill that elementary school students must develop in order to learn science. However, there is not yet enough research about the role that multimodal texts play in scaffolding student reading comprehension of complex scientific processes, such as energy transfer. This study explored how verbal and visual resources (scaffolding level) and individual differences (reading skills) contribute to science reading comprehension. One-hundred and sixty Chilean fifth-graders were assessed on reading skills, vocabulary, and prior science knowledge. A counterbalanced design was used to test two groups: Group 1 reads a text with low multimodal scaffolding and Group 2 reads a text with high multimodal scaffolding. Level of text scaffolding was determined by (1) image function, (2) visual-verbal relations, (3) presence of an explicit explanatory structure, and (4) lexico-grammatical resources. General monomodal and multimodal science reading comprehension were assessed with multiple-choice tests. An ANCOVA analysis revealed non-significant differences between groups after controlling for prior knowledge, fluency, and vocabulary. Likewise, a two-factor ANCOVA analysis showed that the high-multimodal scaffolding text significantly boosted science reading comprehension for low-skilled comprehenders. The paper discusses the implications of these findings for pedagogy and research, aiming to foster multimodal literacy for learning in content areas.  相似文献

The present study followed a sample of first‐grade (N = 316, Mage = 7.05 at first test) through fourth‐grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and reading comprehension to test for the presence of leading and lagging influences. Univariate models indicated growth in vocabulary knowledge, and reading comprehension was determined by two parts: constant yearly change and change proportional to the previous level of the variable. Bivariate models indicated previous levels of vocabulary knowledge acted as leading indicators of reading comprehension growth, but the reverse relation was not found. Implications for theories of developmental relations between vocabulary and reading comprehension are discussed.  相似文献

One of the most important findings to emerge from recent reading comprehension research is that there are large differences between tests in what they assess—specifically, the extent to which performance depends on word recognition versus listening comprehension skills. Because this research used ordinary least squares regression, it is not clear that the findings apply similarly to poor and good readers. The current study uses quantile regression to assess whether there might be differences within tests in the relative contributions of component skills as a function of performance level. There were 834 individuals (ages 8–18) who took 5 reading comprehension tests. Quantile regression showed that, for 3 of 5 tests, the contributions of word recognition and listening comprehension vary as a function of reading comprehension skill. These quantile differences hold across both younger and older readers. Our findings show that what skills a test assesses vary not only with the specific test used but also with how well the person performs.  相似文献

This paper reports two studies that investigate differences in comprehension monitoring skills between good and poor comprehenders. Two groups of 9– to 10-year-olds, who were matched for reading vocabulary and word recognition skills but who differed in comprehension skill, were selected. In the first study, in which the children were required to find anomalous words and phrases, the skilled comprehenders engaged in more accurate monitoring of sentence level anomalies (but not word level anomalies) than did the poorer comprehenders. In the second study, the comprehension monitoring task required the children to detect pairs of sentences, in short texts, that were contradictory. In addition, the working memory demands of the task were varied by placing the two items of inconsistent information either in adjacent sentences, or in sentences that were separated in the text by several others. As in the first study, less-skilled comprehenders performed more poorly on the detection task, but the difference between the groups was considerably more pronounced when the sentences were separated than when they were adjacent. In addition, the children were given a numerical working memory test, and the poorer comprehenders performed more poorly on this test. However, although working memory performance was related to performance on some of the error detection tasks, comprehension ability was also a good, and sometimes better, predictor. The results are discussed in terms of the different cognitive abilities that might contribute to efficient comprehension monitoring.  相似文献

The purpose of this study is to apply the attribute hierarchy method (AHM) to a subset of SAT critical reading items and illustrate how the method can be used to promote cognitive diagnostic inferences. The AHM is a psychometric procedure for classifying examinees’ test item responses into a set of attribute mastery patterns associated with different components from a cognitive model. The study was conducted in two steps. In step 1, three cognitive models were developed by reviewing selected literature in reading comprehension as well as research related to SAT Critical Reading. Then, the cognitive models were validated by having a sample of students think aloud as they solved each item. In step 2, psychometric analyses were conducted on the SAT critical reading cognitive models by evaluating the model‐data fit between the expected and observed response patterns produced from two random samples of 2,000 examinees who wrote the items. The model that provided best data‐model fit was then used to calculate attribute probabilities for 15 examinees to illustrate our diagnostic testing procedure.  相似文献

The aim of this longitudinal study was to investigate the developmental antecedents of reading performance and its subcomponents from the beginning of the first year to the end of the second year of primary school. One‐hundred‐and‐fourteen seven‐year‐old Finnish‐speaking children were tested on reading‐related skills during their first week of school using a test battery designed for school entrants. Following this they were examined six times on word reading and reading comprehension skills. The results showed that the reading‐related variables predicting reading performance varied according to the phase of reading development. Moreover, partially different antecedents predicted word reading and reading comprehension. Word reading was associated with letter knowledge and listening comprehension, whereas initial word reading skill and listening comprehension were highly associated with the development of reading comprehension. The results support the development of reading instructional methods that take into account these differences in the components of reading performance and their development.  相似文献

ABSTRACT

Construct-irrelevant cognitive complexity of some items in the statewide grade-level assessments may impose performance barriers for students with disabilities who are ineligible for alternate assessments based on alternate achievement standards. This has spurred research into whether items can be modified to reduce complexity without affecting item construct. This study uses a generalized linear mixed modeling analysis to investigate the effects of item modifications on improving test accessibility by reducing construct-irrelevant cognitive barriers for persistently low-performing fifth-grade students with cognitive disabilities. The results showed item scaffolding was an effective modification for both mathematics and reading. Other modifications, such as bolding/underlining of key words, hindered test performance for low-performing students. We discuss the findings’ potential impact on test development with universal design.  相似文献

Abstract

This study investigated the contribution of linguistic comprehension to the decoding skills of struggling readers. Participants were 36 children aged between eight and 12 years, all below average in decoding but differing in linguistic comprehension. The children read passages from the Neale Analysis of Reading Ability and their first 25 miscues were categorised into syntactic, semantic, phonemic, and graphophonic similarity. Children were first grouped in terms of higher and lower linguistic comprehension levels. Analysis of miscues showed no differences between the groups in miscue similarity. They were then grouped according to pseudoword reading skill. There were significant differences between the groups for all miscue types except semantic similarity. An analysis of miscues using multiple regression showed that, after taking account of age, pseudoword reading was the best predictor of quality of miscues. In addition, linguistic comprehension contributed to syntactic similarity of miscues over and above decoding.  相似文献

Analyzing examinees’ responses using cognitive diagnostic models (CDMs) has the advantage of providing diagnostic information. To ensure the validity of the results from these models, differential item functioning (DIF) in CDMs needs to be investigated. In this article, the Wald test is proposed to examine DIF in the context of CDMs. This study explored the effectiveness of the Wald test in detecting both uniform and nonuniform DIF in the DINA model through a simulation study. Results of this study suggest that for relatively discriminating items, the Wald test had Type I error rates close to the nominal level. Moreover, its viability was underscored by the medium to high power rates for most investigated DIF types when DIF size was large. Furthermore, the performance of the Wald test in detecting uniform DIF was compared to that of the traditional Mantel‐Haenszel (MH) and SIBTEST procedures. The results of the comparison study showed that the Wald test was comparable to or outperformed the MH and SIBTEST procedures. Finally, the strengths and limitations of the proposed method and suggestions for future studies are discussed.  相似文献

Previous research has indicated a weak to moderate role for word recognition skill in contributing to reading comprehension efficiency in highly experienced adult readers. The goal of this study was to re‐evaluate the strength of this association, including assessment of the contribution of skill in discriminating unfamiliar shapes and identifying letters. Unexpectedly, the results revealed a very strong association between efficiency in reading connected text and word recognition skill, as measured by efficiency of access to the orthographic lexicon. Ability to identify letters rapidly and accurately also contributed to orthographic access skill. These associations were only minimally reduced by controlling for skill in discriminating unfamiliar shapes. The results were interpreted in terms of the verbal‐efficiency theory, according to which rapid and accurate lower‐level processing liberates resources for equally crucial higher‐level comprehension processing, ultimately resulting in more efficient text comprehension.  相似文献

Abstract

This study uses data collected from children in Hong Kong for the PIRLS international reading survey of 2001. A total of 4867 students aged 9 to 10 years from 147 primary schools were assessed. The aim of the study is to investigate the observed differences in comprehension skills displayed in the test results from students at three ability levels. Affective factors (attitudes and reading self‐concept) are also compared for the three groups. Results indicate that the lower‐ability students performed very poorly in all four processes of comprehension — even at the most basic level of retrieval of facts. This weakness at the lower level greatly impaired the students’ ability to operate at higher levels of comprehension involving inference, prediction, integration of ideas and critical evaluation. The weakest readers had extreme difficulty with test items requiring an extended written response. Even on simple multiple‐choice items their performance was inferior to the average and higher‐ability groups. Data from the supplementary questionnaires indicates that across all ability groups the children's attitude toward reading is correlated positively with reading achievement. However, data collected on the students’ reading self‐concept produced anomalous results that cast some doubt on the feasibility of using self‐evaluation and self‐report questionnaires with this age and cultural group. Practical implications from the findings are discussed.  相似文献

One of the major assumptions of item response theory (IRT)models is that performance on a set of items is unidimensional, that is, the probability of successful performance by examinees on a set of items can be modeled by a mathematical model that has only one ability parameter. In practice, this strong assumption is likely to be violated. An important pragmatic question to consider is: What are the consequences of these violations? In this research, evidence is provided of violations of unidimensionality on the verbal scale of the GRE Aptitude Test, and the impact of these violations on IRT equating is examined. Previous factor analytic research on the GRE Aptitude Test suggested that two verbal dimensions, discrete verbal (analogies, antonyms, and sentence completions)and reading comprehension, existed. Consequently, the present research involved two separate calibrations (homogeneous) of discrete verbal items and reading comprehension items as well as a single calibration (heterogeneous) of all verbal item types. Thus, each verbal item was calibrated twice and each examinee obtained three ability estimates: reading comprehension, discrete verbal, and all verbal. The comparability of ability estimates based on homogeneous calibrations (reading comprehension or discrete verbal) to each other and to the all-verbal ability estimates was examined. The effects of homogeneity of item calibration pool on estimates of item discrimination were also examined. Then the comparability of IRT equatings based on homogeneous and heterogeneous calibrations was assessed. The effects of calibration homogeneity on ability parameter estimates and discrimination parameter estimates are consistent with the existence of two highly correlated verbal dimensions. IRT equating results indicate that although violations of unidimensionality may have an impact on equating, the effect may not be substantial.  相似文献
