The objective was to examine the impact of different types of accommodations on performance in content tests such as mathematics. The meta‐analysis included 14 U.S. studies that randomly assigned school‐aged English language learners (ELLs) to test accommodation versus control conditions or used repeated measures in counter‐balanced order. Individual effect sizes (Glass's d) were calculated for 50 groups of ELLs and 32 groups of non‐ELLs. Individual effect sizes for English language and native language accommodations were classified into groups according to type of accommodation and timing conditions. Means and standard errors were calculated for each category. The findings suggest that accommodations that require extra printed materials need generous time limits for both the accommodated and unaccommodated groups to ensure that they are effective, equivalent in scale to the original test, and therefore more valid owing to reduced construct‐irrelevant variance. Computer‐administered glossaries were effective even when time limits were restricted. Although the Plain English accommodation had very small average effect sizes, inspection of individual effect sizes suggests that it may be much more effective for ELLs at intermediate levels of English language proficiency. For Spanish‐speaking students with low proficiency in English, the Spanish test version had the highest individual effect size (+1.45).  相似文献

Does it matter if students are appropriately assigned to test accommodations? Using a randomized method, this study found that individual students assigned accommodations keyed to their particular needs were significantly more efficacious for English language learners (ELLs) and that little difference was reported between students receiving incomplete or not recommended accommodations and no accommodations whatsoever. A sample of third and fourth grade ELLs in South Carolina (N = 272) were randomly assigned to various types of test accommodations on a mathematics assessment. Results indicated that those students who received the appropriate test accommodations, as recommended by a version of a computerized accommodation taxonomy for ELLs (the selection taxonomy for English language learners accommodations; STELLA), had significantly higher test scores than ELLs who received no accommodations or those who received incomplete or not recommended accommodation packages. Additionally, students who were given no test accommodations scored no differently than those students that received accommodation packages that were incomplete or not recommended, given the students' particular needs and challenges. These findings are important in light of research and anecdotal reports that suggest a general lack of systematicity in the current system of assigning accommodations and a tendency to give all available accommodations regardless of individual child characteristics. The results also have important implications for how future accommodation research should be structured to determine the benefits of particular accommodations and accommodation packages. This study would suggest that control and treatment groups should be assembled based on specific student needs in order for direct comparisons to be made.  相似文献

The objectives of this two-part study were to: (a) investigate English learner (EL) accommodation practices on state accountability assessments of reading/English language arts and mathematics in grades 3–8, and (b) conduct a meta-analysis of EL accommodation effectiveness on improving test performance. Across all distinct testing programs, we found that at least one EL test accommodation was provided for both test content areas. The most popular accommodations provided were supplying students with word-to-word dual language dictionaries, reading aloud test directions and items in English, and allowing flexible time/scheduling. However, we found minimal evidence that testing programs provide practitioners with recommendations on how to assign relevant accommodations to EL test takers’ English proficiency level. To evaluate whether accommodations used in practice are supported with evidence of their effectiveness, a meta-analysis was conducted. On average, across 26 studies and 95 effect sizes (N = 11,069), accommodations improved test performance by .16 standard deviations. Both test content and sampling design were found to moderate accommodation effectiveness; however, none of the accommodations investigated were found to have intervention effects that were statistically different from zero. Overall, these results suggest that currently employed EL test accommodations lack evidence of their effectiveness.  相似文献

Glossary and reading aloud test items are commonly allowed in many states' accommodation policies for English language learner (ELL) students for large-scale mathematics assessments. However, little research is available regarding the effects of these accommodations on ELL students' performance. Further, no research exists that examines how students use the accommodations. Using a randomized experimental design and think-aloud procedure, the present study explored the effects of the two accommodations. Results showed no significant effect of glossary, mixed effects of read aloud, and significant interaction effects between students' prior content knowledge and accommodations, which suggests the accommodation was effective for students with content knowledge. Think-aloud data indicated that students were not familiar with, and did not actively utilize the glossary. Implications for the effective use of accommodations and future research are discussed.  相似文献

In recent years, at the same time that performance assessments in science have become more popular, the number of English language learners (ELLs) (i.e., students whose native language is other than English) served by the U.S. educational system has also increased rapidly. While the research base is growing in each of these areas independently, little attention has been paid to their intersection. This case study of the use of a science performance assessment with 96 ELLs in five high school science classes investigated the face, construct, and consequential validity of this intersection. Qualitative and quantitative data analyses showed that both teachers and students had an overall favorable response to the assessment, although students' English comprehension and expression skills were determining factors for certain items. While most responses were reliably scored, ELL spelling and syntax on certain responses were significant sources of error. The degree of specificity of teachers' guidance also significantly affected students' scores. Recommendations from this study include increasing the clarity of an assessment's design, allowing ELLs more time to complete assessments, and scoring by raters who are knowledgeable about typical patterns in written English for this student population. Furthermore, it is recommended that the use of performance assessments with ELLs be exploratory until such time as their validity and reliability with this population can be more adequately established.

The performance of English language learners (ELLs) has been a concern given the rapidly changing demographics in US K-12 education. This study aimed to examine whether students' English language status has an impact on their inquiry science performance. Differential item functioning (DIF) analysis was conducted with regard to ELL status on an inquiry-based science assessment, using a multifaceted Rasch DIF model. A total of 1,396 seventh- and eighth-grade students took the science test, including 313 ELL students. The results showed that, overall, non-ELLs significantly outperformed ELLs. Of the four items that showed DIF, three favored non-ELLs while one favored ELLs. The item that favored ELLs provided a graphic representation of a science concept within a family context. There is some evidence that constructed-response items may help ELLs articulate scientific reasoning using their own words. Assessment developers and teachers should pay attention to the possible interaction between linguistic challenges and science content when designing assessment for and providing instruction to ELLs.  相似文献

The development of English language learners (ELLs) was explored from kindergarten through eighth grade within a nationally representative sample of first-time kindergartners (N = 19,890). Growth curve analyses indicated that, compared to native English speakers, ELLs were rated by teachers more favorably on approaches to learning, self-control, and externalizing behaviors in kindergarten and generally continued to grow in a positive direction on these social/behavioral outcomes at a steeper rate compared to their native English-speaking peers, holding other factors constant. Differences in reading and math achievement between ELLs and native English speakers varied based on the grade at which English proficiency is attained. Specifically, ELLs who were proficient in English by kindergarten entry kept pace with native English speakers in both reading and math initially and over time; ELLs who were proficient by first grade had modest gaps in reading and math achievement compared to native English speakers that closed narrowly or persisted over time; and ELLs who were not proficient by first grade had the largest initial gaps in reading and math achievement compared to native speakers but the gap narrowed over time in reading and grew over time in math. Among those whose home language is not English, acquiring English proficiency by kindergarten entry was associated with better cognitive and behavioral outcomes through eighth grade compared to taking longer to achieve proficiency. Multinomial regression analyses indicated that child, family, and school characteristics predict achieving English proficiency by kindergarten entry compared to achieving proficiency later. Results are discussed in terms of policies and practices that can support ELL children's growth and development.  相似文献

Word problems for English language learners (ELLs) at risk for math disabilities are challenging in terms of the constant need to develop precise math language and comprehension knowledge. As a result of this, ELLs may not only need math support but also reading and linguistic support. The purpose of this study was to assess the effectiveness of a word problem–solving strategy called Estratégica Dinámica de Matemáticas (EDM). This strategy was designed to provide math support in the native language based on students' math comprehension levels. A changing criterion multiple baseline design was used to instruct six second-grade Latino ELLs at risk for math disability. As compared with the baseline phase, EDM increased word problem solving for all participants. All students' level of performance were maintained and generalized during follow-up sessions. This study has implications for a native language intervention that focuses on strategy training to facilitate word problem–solving performance.  相似文献

Among the several forms of accommodations used in the assessment of English language learners (ELLs), language-based accommodations are the most effective in making assessments linguistically accessible to these students. However, there are significant challenges associated with the implementation of many of these accommodations. This article reviews studies that explain the impact of language factors on the assessment of ELLs, presents major forms of language-based accommodations, and discusses how computers can assist in the proper administration of these accommodations.  相似文献

Critical thinking is deemed as an ideal in academic settings, but cultural differences in critical thinking performance between Asian and Western students have been reported in the international education literature. We examined explanations for the observed differences in critical thinking between Asian and New Zealand (NZ) European students, and tested hypotheses derived from research in international education and cultural psychology. The results showed that NZ European students performed better on two objective measures of critical thinking skills than Asian students. English proficiency, but not dialectical thinking style, could at least partially if not fully explain these differences. This finding holds with both self-report (Study 1) and objectively measured (Study 2a) English proficiency. The results also indicated that Asian students tended to rely more on dialectical thinking to solve critical thinking problems than their Western counterparts. In a follow-up data analysis, students' critical thinking was found to predict their academic performance after controlling for the effects of English proficiency and general intellectual ability, but the relationship does not vary as a function of students' cultural backgrounds or cultural adoption (Study 2b). Altogether, these findings contribute to our understanding of the influence of culture on critical thinking in international education.  相似文献

Providing appropriate test accommodations to most English language learners (ELLs) is important to facilitate meaningful inferences about learning. This study compared teacher large-scale test accommodation recommendations to those from a literature- and practitioner-grounded accommodation selection taxonomy. The taxonomy links student-specific needs, strengths, and schooling experiences to large-scale test accommodation recommendations that differentially minimize barriers of access for students with different profiles. A blind panel of experts rated four sets of recommendations for each of 114 ELLs. Results found the taxonomy was a significantly better fit for distinguishing accommodations by student need than teacher recommendations. Further, the fit of teacher recommendations showed no difference when the teacher used a structured data collection procedure to gather profile information about each of their ELLs and when they did not, and teachers’ recommendations were not found to differ significantly from a random set of accommodations. Findings are consistent with previous literature that suggests the task of matching specific accommodations to individual needs, rather than the task of identifying individual needs, is where teachers struggle in recommending appropriate test accommodations.  相似文献

《理论付诸实践》2012,51(4):297-304
In this article, we put forward 4 pedagogic principles that we consider to be particularly important in helping English language learners (ELLs) to succeed in school. These principles are: creating multiple and varied opportunities for ELLs to use the target language in both speech and writing, promoting high engagement by building on students' interests, connecting the curriculum to ELLs' lives and their funds of knowledge, and working toward a tangible goal. We illustrate these principles in action by presenting 2 case studies drawn from our research. They show how the teachers with whom we worked used these principles to meet their students' needs in two demographically different classroom contexts.  相似文献

Despite the expectation that all students should achieve high academic standards, content area instruction and English for speakers of other languages instruction for English language learners (ELLs) have traditionally been conceptualized as separate domains, resulting in educational inequities for ELLs. This is because effective instruction to promote academic achievement for ELLs requires integration of content and language. Such inequities are more pronounced in urban schools where ELLs are disproportionately represented. In science education, research on instructional interventions to simultaneously promote science and English proficiency of ELLs has begun to emerge in recent years. Grounded in this emerging research literature, we offer specific instructional strategies to integrate science and English proficiency for ELLs in five domains: (a) literacy strategies with all students, (b) language support strategies with ELLs, (c) discourse strategies with ELLs, (d) home language support, and (e) home culture connections.  相似文献

The Critical Role of Vocabulary Development for English Language Learners   总被引:2,自引:0,他引:2  
English language learners (ELLs) who experience slow vocabulary development are less able to comprehend text at grade level than their English‐only peers. Such students are likely to perform poorly on assessments in these areas and are at risk of being diagnosed as learning disabled. In this article, we review the research on methods to develop the vocabulary knowledge of ELLs and present lessons learned from the research concerning effective instructional practices for ELLs. The review suggests that several strategies are especially valuable for ELLs, including taking advantage of students' first language if the language shares cognates with English; ensuring that ELLs know the meaning of basic words, and providing sufficient review and reinforcement. Finally, we discuss challenges in designing effective vocabulary instruction for ELLs. Important issues are determining which words to teach, taking into account the large deficits in second‐language vocabulary of ELLs, and working with the limited time that is typically available for direct instruction in vocabulary.  相似文献

Research indicates that the performance-gap between English Language Learners (ELLs) and their non-ELL peers is partly due to ELLs' difficulty in understanding assessment language. Accommodations have been shown to narrow this performance-gap, but many accommodations studies have not used a randomized design and are based on relatively small sample sizes. Addressing such issues, we administered a standard-based mathematics assessment to approximately 3,000 Grade 9 ELL and non-ELL students under five different language-based accommodations. Results indicate that many of these accommodations did not produce significant gains for the recipients. Some even had a negative impact. We believe several factors may explain these findings. First, newer assessments, including those developed for this study, may have been linguistically modified to the point that further modification has only a limited effect. Second, the language of instruction may have not adequately prepared students for the assessment. If the language of instruction (textbook, etc.) contains unnecessary linguistic complexity, then students may not have had the opportunity to learn the assessed content. A third factor is students’ unfamiliarity with these accommodations because they are seldom used in classroom instruction and teacher assessments. We discuss our findings and implications for policymakers, assessment developers, practitioners, and researchers.  相似文献

English language learners (ELLs) are the fastest growing subgroup in American schools. These students, by a provision in the reauthorization of the Elementary and Secondary Education Act, are to be supported in their quest for language proficiency through the creation of systems that more effectively measure ELLs’ progress across years. In the past, ELLs’ progress has been based on students’ prior scores measuring the same construct. To disentangle effectiveness from achievement, the reporting has generally targeted mean-group activity. In contrast, student growth percentiles (SGPs) provide a comparison of students’ growth with others who have the same achievement score history. By examining the construct measured by an English language proficiency test as manifested in student scores in Speaking, Listening, Reading and Writing, this article outlines the use of SGPs in providing information on how much each student needs to grow, which will allow educators to more effectively apply differential formative instructional strategies.  相似文献

Two studies examined students' intuitive physics ability and characteristics associated with physics competence. In Study 1, although many students did well on a physics quiz, more than 25% of students performed below levels predicted by chance. Better performance on the physics quiz was related to physics grades, highest level of math taken, and students' perceived scholastic competence, but was not related to a number of other hypothesized personality variables. Study 2 further explored personality and academic variables and also examined students' awareness of their own physics ability. Results indicate that the personality variables were again unrelated to ability, but narcissism may be related to subjects' estimates of knowledge. Also, academic variables and how important students think it is to understand the physical world are related to both measured and estimated physics proficiency. © 2002 Wiley Periodicals, Inc.

This article describes English language proficiency and bilingual verbal ability for a sample of 209 students aged 10 to 16 from three immigrant groups—Chinese, Dominican, and Haitian. Sources of data included structured student interviews, parent interviews, and individual language assessments. On average, students' English language proficiency was far below their age and grade level with significant differences among the groups. Estimates of students' language ability improved once their skills in their first language were considered as demonstrated by the bilingual verbal ability scores. Results from this study demonstrate the need to consider both English and first language skills in assessing the language abilities of these students and in promoting educational access and equity for recent immigrants.  相似文献

Considerable evidence indicates that self-efficacy, task value, anxiety, and the use of language learning strategies are related. However, there is currently an insufficient understanding about their relations in high-stakes testing contexts. The author aimed to investigate how well social factors, test value, anxiety, test performance, and learning strategies predict high school students' self-efficacy in preparing for the English listening test as part of the University Entrance Examination in Taiwan. This research involved a large-scale questionnaire survey and a collection of students' English test scores. The participants were 636 students in Grade 12 of high school in Taiwan. A quantitative analysis of the questionnaire was conducted via hierarchical regression analysis. The results show that students' recent English test performance and test anxiety were two strong predictors of self-efficacy in preparing for the high-stakes test. In addition, resource management and metacognitive listening strategies had better predictive power over prior English level and test value.  相似文献
