Academic language is critical for English learners (ELs) to succeed in the science classroom. This study analyzed the instructional practices centered around academic language taking place in eight, fifth-grade classrooms during a grant-funded project. Observational data collected through a classroom observation instrument were analyzed to describe and compare the instructional practices occurring in treatment and control classrooms when teachers and students used academic language. Our findings show both treatment and control classrooms using academic language during the course of the intervention study, but the instruction looked markedly different in each setting. These differences provide valuable insight for practitioners and researchers concerned with the academic language development of ELs in science classrooms.  相似文献

This study used a within-subjects design to explore two instructional conditions for developing vocabulary in second-grade Spanish-speaking English learners (ELs)—extended instruction and embedded instruction implemented during shared interactive reading. Words assigned to the extended condition were directly taught using a multifaceted approach that included visuals, bilingual definitions, examples, spelling, and partner-talk about the words’ meaning. Words assigned to the embedded condition were taught solely through brief definitions to embedded text, writing activities, and songs. In the control condition students heard the target words read aloud during shared interactive reading but without definitions or direct instruction. The study also explored the interaction between instructional condition and word type. Four types of words—abstract cognates, abstract noncognates, concrete cognates, and concrete noncognates—were randomly assigned to each condition. Nine teachers in four schools and 187 second-grade ELs participated in this within-subjects intervention, which took place in transitional bilingual classrooms. Findings indicated that across all word types, both extended and embedded instruction were more effective than the control condition in helping ELs acquire vocabulary. Findings also indicated that extended instruction was more effective then embedded instruction for all word types except concrete cognates suggesting that these young Spanish-speaking ELs were advantaged by word knowledge in their home language. Finally, while embedded instruction was less effective than extended instruction, it was much more effective than a control condition. Embedded instruction takes significantly less preparation and instructional time than extended instruction, offering teachers a practical way to teach more vocabulary to ELs.  相似文献

This year-long, quasi-experimental study investigated the impact of the use of netbook computers and interactive science software on fifth-grade students’ science learning processes, academic achievement, and interest in further science, technology, engineering, and mathematics (STEM) study within a linguistically diverse school district in California. Analysis of students’ state standardized science test scores indicated that the program helped close gaps in scientific achievement between at-risk learners (i.e., English learners, Hispanics, and free/reduced-lunch recipients) and their counterparts. Teacher and student interviews and classroom observations suggested that computer-supported visual representations and interactions supported diverse learners’ scientific understanding and inquiry and enabled more individualized and differentiated instruction. Finally, interviews revealed that the program had a positive impact on students’ motivation in science and on their interest in pursuing science-related careers. This study suggests that technology-facilitated science instruction is beneficial for improving at-risk students’ science achievement, scaffolding students’ scientific understanding, and strengthening students’ motivation to pursue STEM-related careers.  相似文献

The goal of the present study was to compare children’s word learning through print text, video, and electronic text in the context of a cross-age peer-learning program implemented in linguistically diverse kindergarten and fourth grade classrooms that included English Learners (ELs) and their non-EL peers. Children were assessed at pre- and post-test on measures of receptive and expressive vocabulary knowledge. Findings showed effects of media type on word learning. Effects differed across grades (i.e., kindergarten and fourth grade, language background (i.e., non-EL and EL), and knowledge types (i.e., receptive and expressive). In kindergarten, results suggest that video may be more helpful than electronic texts for supporting receptive and expressive vocabulary, and video may be more helpful than both print and electronic texts for supporting the expressive vocabulary of ELs. In fourth grade, results suggest that video and electronic texts may be more helpful than print texts for supporting expressive vocabulary for non-ELs but not for ELs.  相似文献

The purpose of this study was to develop a computer-based measure of elementary students’ science talk and to report students’ benchmarks. The development procedure had three steps: defining the framework of the test, collecting and identifying key reference sets of science talk, and developing and verifying the science talk instrument. The Science Talk Test (STT), consisting of semi-structured items, was developed for a framework of exemplars from inquiry classrooms representing three inquiry components (i.e. identifying questions, designing methods and presenting evidence, and drawing evidence-based conclusions) for two types of science talk (i.e. factually oriented and evaluative discourses). Grades 4 and 6 students (N = 281) were selected from three levels of urbanization representative of Taiwan to verify the STT and to establish performance benchmarks. The STT’s reliability, validity, and item parameters were found to be reasonable. Students performed better in the factually oriented talk than in the evaluative talk. Designing methods and presenting evidence was more difficult than the other two types of inquiry talk. Students’ science talk ability was predictable with prior scientific knowledge and language ability measures. Practical use of the STT, explicit instruction, and future research are recommended.  相似文献

The purpose of this study was to compare and describe 8 fifth-grade classrooms by their teachers pedagogy during a quasiexperimental, longitudinal, and field-based project focused on increasing English language learners' (ELLs') achievement in science and language. The larger study found statistically significant and positive intervention effects in favor of the treatment group on measures of science and language achievement. This study adds an in-depth analysis of the teacher pedagogical practices contributing to students' science and language achievement as captured by an observational instrument used during the project. Results from the analysis show how treatment teachers, when compared to control teachers, focused on activities promoting verbal and written interaction among the students and dense cognitive language use during science inquiry instruction. The findings support the importance of effectively using language in the science classroom to improve ELLs' science and language achievement. Implications for future research and practice are discussed.  相似文献

Reading and comprehending content area texts is important for academic and professional success as well as life skills necessary to maintain good health and quality lifestyle. Spanish speaking English language learners have shown poor performance on high-stakes assessments in reading comprehension. The number of Spanish speaking English learners (ELs) in our schools continues to increase at a fast pace, and therefore it is imperative that we address their reading comprehension needs swiftly and effectively. The text structure strategy has shown positive results on comprehension outcomes in many research studies with students at Grades 2, 4, 5, and 7. This study is the first implementation of instruction about the text structure strategy expressly designed to accommodate the linguistic and comprehension needs of Spanish speaking ELs in Grades 4 and 5. Strategy instruction on the web for English learners (SWELL) was designed to deliver instruction about the text structure strategy to Spanish speaker English learners. A randomized controlled study with pre and post-tests was conducted with 14 classrooms at fourth-grade and 17 classrooms at fifth-grade in high poverty schools where over 85% of students were Spanish speaking bilinguals or ELs. Analysis of data using multi-level models show moderate to large-effects favoring the students in the SWELL classrooms over the business as usual control classrooms on important measures such as a standardized reading comprehension test and main idea and cloze tasks. This research has practical implications for the use of web-based tools to provide high-quality and supportive instruction to improve Spanish speaking ELs reading comprehension skills.  相似文献

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based project, the sample of project teachers is stratified to select teachers with a high number of science PD hours versus those with few hours. While there were no significant differences in the mean total scores for kit-based students with low PD versus high PD teachers, the kit-based classrooms scored significantly higher than students in nonkit classrooms on both the pretest and posttest, though there were significantly more minutes of science instruction in the nonkit classrooms. Finally, nonkit teachers taught more units of shorter length and reported lower levels of preparedness to use reform pedagogical approaches.  相似文献

Considering the rising proportion of English learners (ELs) in general education, little is known about how this change in classroom composition relates to the frequency of instructional activities and skills. This study uses a multimodal perspective on learning mathematics in a multilingual context, which recognizes the diverse modes of communication that students draw on in mathematics classrooms. We examined national data using quantitative analyses and investigated the mathematics practices that were more likely to occur in kindergarten classrooms that did and did not have ELs. We found teachers reported greater frequency of manipulatives and count/calendar activities in mathematics instruction when there were EL students in the classroom. Teachers in classrooms with ELs also reported a greater frequency of mathematics content that involved teaching shapes and practical skills. The findings indicate that teachers tended towards a supportive multimodal approach to instruction when ELs were present.  相似文献

Research Findings: This study examined the potential impacts of ongoing participation (twice weekly for 30 weeks) in teacher–child managed whole-group language and literacy instruction on prekindergarten children’s social interaction with classmates. Teacher–child managed whole-group instruction that provides children with opportunities to engage with all of their classmates regularly may potentially deepen the social depth within a classroom (i.e., the frequency with which children regularly interact with each other). Provision of this type of instruction occurred via teachers’ implementation of a whole-class literacy curriculum twice weekly. Participants were 119 preschoolers who received an experimental literacy curriculum in 26 classrooms and 76 children in 17 business-as-usual control classrooms. Condition predicted the strength of children’s social interaction, suggesting that children in experimental classrooms had relatively stronger social ties with peers than children in control classrooms. Practice or Policy: The findings suggest that participation in ongoing teacher–child managed whole-group instruction could facilitate stronger social connections among preschool children.  相似文献

This meta-analysis synthesizes the last two decades of experimental and quasi-experimental research on reading instruction across academic contexts (e.g., social studies, science, mathematics, English language arts) for English learners (ELs) in grades 4 through 8, to determine (a) the overall effectiveness of reading instruction for upper elementary and middle school students who are ELs and (b) how the magnitude of the effect varies based on student, instructional, and study characteristics. The analysis included a total of 11 studies with 46 individual effect sizes and yielded a mean effect size of g?=?0.35 across all (i.e., standardized and unstandardized) reading measures, g?=?0.01 across standardized reading measures, and g?=?0.43 across unstandardized reading measures. For all reading, unstandardized reading, all vocabulary, and unstandardized vocabulary measures, results suggest that higher quality studies tended to have smaller effects, and these effects were even more evident for unstandardized measures (i.e., one unit increase in study quality was associated with decreased effects: g?=?0.21, g?=?0.30, g?=?0.24, g?=?0.30, respectively). For all comprehension measures, effects were larger for instruction that included both vocabulary and comprehension (g?=?0.39) than for instruction that focused on vocabulary alone (g?=?0.08). Results suggest the benefit of developing and refining high-impact approaches to reading instruction for ELs that can be delivered across content areas and grades.  相似文献

This paper presents the findings from a randomized control trial study of reading/literacy-integrated science inquiry intervention after 1 year of implementation and the treatment effect on 5th-grade low-socio-economic African-American and Hispanic students’ achievement in science and English reading. A total of 94 treatment students and 194 comparison students from four randomized intermediate schools participated in the current project. The intervention consisted of ongoing professional development and specific instructional science lessons with inquiry-based learning, direct and explicit vocabulary instruction, and integration of reading and writing. Results suggested that (a) there was a significantly positive treatment effect as reflected in students' higher performance in district-wide curriculum-based tests of science and reading and standardized tests of science, reading, and English reading fluency; (b) males and females did not differ significantly from participating in science inquiry instruction; (c) African-American students had lower chance of sufficiently mastering the science concepts and achieving above the state standards when compared with Hispanic students across gender and condition, and (d) below-poverty African-American females are the most vulnerable group in science learning. Our study confirmed that even a modest amount of literacy integration in inquiry-based science instruction can promote students' science and reading achievement. Therefore, we call for more experimental research that focus on the quality of literacy-integrated science instruction from which middle grade students, particularly low-socio-economic status students, can benefit.  相似文献

Positioned in the Hong Kong education context, this article evaluates the effects of teaching science through home and second languages (i.e. Chinese and English) in Secondary 2 (or eighth grade) science classrooms. A total of 479 students, divided into two language instruction groups, participated in a teaching intervention comprising 16 lessons on the topic of ‘Making Use of Electricity’. Informed by the results of a mixed-methods study with a quasi-experimental design, with data collected from science diagnostic tests, inquiry questions and focus group interviews, this article reports that Chinese is the most advantageous language of instruction for low- and middle-ability science students, whereas English is more favourable for their high-achieving peers. Whilst Hong Kong students who learnt the focal topic in English were able to rid themselves of certain naive ideas generated from the translation of science terms into Chinese (e.g. pencil ‘鉛筆’ is translated as ‘lead pen’ in Chinese), they were also found to have misconceptions about certain scientific concepts. For example, they were confused about ‘open’ and ‘closed’ circuits because they mixed up the words ‘open’ (‘放’) and ‘switch on’ (‘啟’) in English. The study’s broad implications for language support and a mixed-code approach in science teaching worldwide are discussed.

Recent calls for border crossing between reading and science have heightened the need to support science teachers in integrating reading into science and to verify the robustness of this approach in the context of inquiry‐based science. In this paper, we share what we did, found, and learned in a collaborative project in which a team of university‐based reading educators and school‐based science teachers worked together to infuse reading strategy instruction and quality science trade books into inquiry‐based sixth‐grade science classrooms. We suggest that infusing reading into middle school science enhances science teaching and learning, but is a complex, multifaceted undertaking.  相似文献

Inquiry-based science teaching involves supporting pupils to acquire scientific knowledge indirectly by conducting their own scientific experiments, rather than receiving scientific knowledge directly from teachers. This approach to instruction is widely used among science educators in many countries. However, researchers and policymakers have recently called the effectiveness of inquiry approaches into doubt. Using nationally-representative linked survey and administrative data we find little evidence that the frequency of inquiry-based instruction is positively associated with teenagers’ performance in science examinations. This finding is robust to the use of different measures of inquiry, different measures of attainment, across classrooms with varying levels of disciplinary standards and across gender and prior attainment subgroups.  相似文献

Science learning is inextricably tied to two aspects of students’ lives: literacy and culture. While English Learners (ELs) who speak a non-English native language are typically the focus in this line of scholarly inquiry, deaf and hard-of-hearing (DHH) students occupy a distinct space in this conversation. For DHH learners, literacy levels can be hindered by an early dependence on a more survival-based language learning model that postpones basic scientific inquiry. The vocabulary for curiosity is limited, which in turn affects the educational culture. DHH learners have a unique culture that demands an appropriate science curriculum, which thus far has not been explored or attempted for either DHH learners or their educators. Data collected consisted of interviews with teachers of DHH students, as well as observational data collected from a high-minority urban K-8 school for DHH students. The analysis revealed that, first, many of the teachers had limited preparation to teach science content. Second, DHH teachers used inconsistent instructional strategies ranging from drawing pictures to building models. Third, the modifications provided to DHH science learners were mostly limited to visual support and repetition. Implications for teacher education programs include instruction focused on specific supports for DHH students and co-teaching methods, and deeper investigation of inquiry-based science practices. Implications for classroom practices include providing hands-on, inquiry-based instruction, working closely with parents, and developing students’ and teachers’ understanding of scientific inquiry.

Six remedial reading teachers in a large, rural school district participated in a form of professional development called Teaching as Intentional Learning, based on an inquiry process. Their topic of inquiry was formative assessment. Professional development comprised both direct instruction and inquiry learning in teachers’ own classrooms. This study describes the strategies they experimented with, their professional growth in formative assessment, and effects on students. All six teachers showed important professional growth, as indicated by their own reflections and also by their supervisor’s observations. In First Grade, at‐risk students assigned to these project teachers had increased reading readiness scores on one measure (DIBELS PSF) compared with at‐risk students assigned to non‐project teachers.  相似文献

Scientific inquiry activities are considered as productive science instruction to improve students’ science learning and achievement. Supportive teacher-student relationships and positive disciplinary climate in the classroom are also two important factors that could facilitate student learning. This study investigates whether the association between the inquiry-based science activities and student science achievement varies by teacher support and disciplinary climate in science classrooms, particularly when taking into consideration of student gender difference and socioeconomic status (SES). This study performed regression analyses using Beijing, Shanghai, Jiangsu, and Guangdong (B-S-J-G-China) students’ science performance and background survey data of 2015 Program for International Student Assessment (PISA). Results showed that disciplinary climate, rather than teacher support, could moderate the association between inquiry-based science activities and student science achievement for both genders. Implications for instruction and further research were discussed as well.  相似文献

Based on data collected from 211 elementary school children in central Taiwan over four years, the role of temperament in science achievement was examined with multivariate analysis of covariance (MANCOVA) with repeated measures design. The results revealed that the students’ science achievement is stable over time. The task orientation characteristics (i.e., distractibility, hyperactivity, and persistence) identified by previous research as important in mathematics and reading achievement are not consistent with the findings of this study that although the impacts of distractibility and persistence are significant, the simple effect of activity level on science achievement was not significant. However, the interaction effect of activity level and persistence is significant. Further break down analyses conducted to pursuit the interaction effect revealed that: (1) persistence has a consistent significant positive effects on all children over the years, except for the ones with high activity level (the upper 25th percentile); and (2) activity level has significant negative effects on high persistence (the upper 25th percentile) children only, and the interaction effect of activity level increases over time—the older the child the more significant the influence. Also, the tendency of approach/withdraw has significant impact on science achievement The educational implications of the findings include: (1) teachers of high activity students with high persistence may need to consider the match between children’s interests and contents of instruction; (2) a good match between children’s individual differences in distractibility, persistence, and approach need to be considered in contents, expectations, and interactions of the instruction.  相似文献
