In science classes, teachers must consider the need for explicit, systematic reading instruction for students with learning disabilities (LD) while navigating the constructivist and activity‐oriented methods typically employed in science instruction. The complexity of scientific information conveyed through print may make reading science texts the greatest challenge that students with LD encounter in school. Fortunately, researchers have established that, by fostering students’ prior knowledge, providing text enhancements, and teaching reading comprehension strategies, students’ understanding of science text is improved. Effective instructional approaches and strategies for reading are reviewed and implications for teaching students with LD noted. 相似文献

Researchers have shown a growing interest in science teachers’ professional knowledge in recent decades. The article focuses on how chemistry teachers impart chemical bonding, one of the most important topics covered in upper secondary school chemistry courses. Chemical bonding is primarily taught using models, which are key for understanding science. However, many studies have determined that the use of models in science education can contribute to students’ difficulties understanding the topic, and that students generally find chemical bonding a challenging topic. The aim of this study is to investigate teachers’ knowledge of teaching chemical bonding. The study focuses on three essential components of pedagogical content knowledge (PCK): (1) the students’ understanding, (2) representations, and (3) instructional strategies. We analyzed lesson plans about chemical bonding generated by 10 chemistry teachers with whom we also conducted semi-structured interviews about their teaching. Our results revealed that the teachers were generally unaware of how the representations of models they used affected student comprehension. The teachers had trouble specifying students’ difficulties in understanding. Moreover, most of the instructional strategies described were generic and insufficient for promoting student understanding. Additionally, the teachers’ rationale for choosing a specific representation or activity was seldom directed at addressing students’ understanding. Our results indicate that both PCK components require improvement, and suggest that the two components should be connected. Implications for the professional development of pre-service and in-service teachers are discussed. 相似文献

ABSTRACTReading is a tool that promotes the learning of science across schooling. Scientific texts are conceptually and linguistically complex, especially for students from low-income contexts because they have neither the experience with the language nor the literacy skills to face the challenges of scientific knowledge. This study used a mix method approach to compare the cognitive scaffolding practiced by teachers during science reading activities in high- and low-performing schools. Three teachers and 141 fourth grade students from low socioeconomic background schools participated in 48 class sessions. Classes were video-recorded and transcribed. The data were analyzed using Sanchez’ Pedagogic Practice Analysis System. The results show that teachers from both types of schools continuously use reading as a tool for learning. The effective teacher uses reading with non-invasive scaffolding and varied verbal participation to elaborate knowledge, promoting literal and inferential comprehension and more opportunities for the students to construct knowledge. By contrast, less effective teachers use reading with invasive scaffolding and little verbal participation of the students to consolidate knowledge, promoting mainly literal comprehension. This study shed light on different approaches teachers use to foster reading comprehension for science learning. 相似文献

There are few research studies on the effects of teaching comprehension strategies to young children in the primary grades. Using a Dominant–Less Dominant Mixed Model design employing both qualitative and quantitative data collection, we evaluated two approaches for teaching comprehension strategies to 7- and 8-year-old children in four second-grade classrooms using science information texts. The first approach focused upon explicitly teaching a series of single comprehension strategies, one-at-a-time (SSI). The second approach focused on teaching a “set” or “family” of transacted comprehension strategies within a collaborative, interactive and engaging routine (TSI). Results showed no difference between teaching young children a “set” of comprehension strategies and teaching comprehension strategies explicitly, one-at-a-time on their reading comprehension performance as measured by a standardized test of reading comprehension, recall of main ideas from reading two 200 word passages from information texts, a reading motivation survey and a strategy use survey. Results showed significant differences between students taught a set of comprehension strategies on measures of elaborated knowledge acquisition from reading science books (detail idea units recalled), retention of science content knowledge, and significantly improved criterion or curriculum-based reading comprehension test scores. These benefits favoring TSI over SSI are important because the learning curve is relatively steep for teachers to develop the ability to teach and for young children to develop the ability to coordinate a “set” of transacted comprehension strategies. 相似文献

ABSTRACTReading 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 study examined the relationships between teachers’ metacognitive knowledge of reading strategies and their students’ metacognitive knowledge and reading comprehension. The study was carried out among language art teachers (N?=?34) and their students (N?=?534) in the last year of primary school (ninth grade) in Estonia. Multilevel modeling was used to test the hypotheses of relationships between students’ metacognitive knowledge and reading comprehension, while controlling for students’ previous reading comprehension (in eighth grade) as well as the relations between teachers’ metacognitive knowledge of reading strategies and students’ metacognitive knowledge and comprehension. The results showed that students’ metacognitive knowledge of reading strategies related to their reading comprehension, concurring with previous findings. The main finding was that teachers’ metacognitive knowledge of reading strategies significantly related to their students’ metacognitive knowledge, but not to reading comprehension. These results indicate that students’ reading comprehension may be supported by improving their metacognitive knowledge of reading strategies. In addition, the findings highlight the importance of teachers’ metacognitive knowledge in students’ metacognitive knowledge. 相似文献

The language used in environmental education texts has linguistic features that affect students' comprehension of concepts and their ability to envision solutions to environmental education problems. This paper shows what 143 middle school students focused on and what they failed to focus on when reading texts about biodiversity issues and identifies linguistic features of the texts that can account for this. Since much evaluation of students' knowledge of academic subjects, including environmental education, is done through reading and writing assignments, it is important to examine how environmental education texts present issues to students and what students write after reading environmental education texts. We suggest that features of texts such as abstract nouns and lack of explicit agents impede students' full comprehension of complex issues and obscure the causes and solutions to environmental problems. We present guidelines for teachers and materials writers to make abstract concepts more accessible to middle school students. 相似文献

Previous research has documented the role of readers’ existing topic knowledge in supporting students’ comprehension of text; yet, we know less about how to build students’ knowledge in order to support comprehension and vocabulary learning. In the current study, we test the hypothesis that knowledge can be built and leveraged simultaneously in the interest of students’ literacy development through the use of conceptually coherent text sets. Fourth grade students (N = 59) were randomly assigned to read either a set of six informational texts that cohered around a set of concepts related to the topic birds (CC texts) or a set of texts that addressed a range of topics (NCC group texts). After reading, we assessed students’: (1) knowledge of the concepts in the conceptually coherent text set, (2) knowledge of target concept-related words that appeared in their respective text sets, (3) knowledge of general academic words that appeared in both texts sets, (4) comprehension of a novel text on a related topic, and (5) interest in the topic of the conceptually coherent texts. Results revealed that students who read the conceptually coherent texts demonstrated more knowledge of the concepts in their texts, more knowledge of the target words in their texts, and had better recall of the novel text compared to students who read unrelated texts. Findings suggest that there is potential for knowledge and vocabulary to be built during English language arts through a focus on conceptual coherence in the design of reading experiences for students. 相似文献

Many primary grade students are not afforded nonfiction-rich opportunities, with fiction comprising the majority of books read aloud in classrooms. With the Common Core Standards recommending that half of the texts made available to students be nonfiction, educators are increasing their use of informational text. The present study explored the impact of explicitly teaching reading comprehension and vocabulary strategies with nonfiction text compared to fiction text in primary-grade classrooms. Two first-grade (n = 39; 25 male, 14 female) and one second-grade class (n = 20; 13 male, 7 female) participated in the quantitative study that followed a repeated measures design in which the students alternated every 2 weeks between fiction-based instruction and nonfiction-based instruction for a total of 8 weeks. Vocabulary and use of comprehension strategies were assessed at the end of each 2-week period. Overall findings indicated that students were better able to apply the comprehension strategies and define vocabulary following nonfiction-based instruction; they also were more motivated to read informational text. The authors recommend that teachers use more nonfiction texts in the primary grades to support students’ reading comprehension and vocabulary development. 相似文献

Many struggling readers, students with English as a second language, and children with disabilities do not engage in the strategies that good readers use when reading for understanding. Reading comprehension depends upon the students’ ability to successfully use strategies to monitor and control their own comprehension. Teachers need to help students develop skills that will aid in reading comprehension. The think-aloud is one strategy that can help struggling readers improve fluency and comprehension. One of the most important components to determine the success of the think-aloud is the teacher’s ability to model and facilitate the think-aloud procedure. The teacher needs to have a basic understanding of what is meant to be accomplished using this method. This article profiles how three teachers model and facilitate a think-aloud with three struggling readers. 相似文献

The language used to construct knowledge, beliefs, and worldviews in school science is distinct from the social language that students use in their everyday ordinary life. This difference is a major source of reading difficulty for many students, especially struggling readers and English‐language learners. This article identifies some of the linguistic challenges involved in reading middle‐school science texts and suggests several teaching strategies to help students cope with these challenges. It is argued that explicit attention to the unique language of school science should be an integral part of science literacy pedagogy. 相似文献

Knowledge foundations for teaching reading and spelling 总被引：1，自引：0，他引：1

Changes in education policy, the accumulation of research evidence that skilled instruction prevents and ameliorates reading
failure, accountability requirements, and a new emphasis on multi-tiered interventions in schools are all causing a growing
interest in improving teacher knowledge and skill in reading instruction. Consensus frameworks that explain reading development
and individual differences provide an outline for what teachers need to know. The details of that content, however, including
the English phonological system, the organization of English orthography, and the language structures that are processed during
reading and writing, are challenging for teachers to learn. Recent studies are reviewed that investigate the relationship
between teacher knowledge, practice, and student outcomes. The paper argues that teachers must have considerable knowledge
of language structure, reading development, and pedagogy to differentiate instruction for diverse learners. Policy mandates
for improvement of reading achievement should provide for more effective teacher education, as the knowledge base is not learned
casually or easily. Research on how teachers best develop expertise should inform our licensing and professional development
programs. 相似文献

- Connectives (words such as moreover, because and although) help the reader in establishing coherence between text parts.
- In primary school, for fifth graders, knowledge of connectives has been shown to be uniquely related to English text comprehension controlling for reading fluency and general vocabulary knowledge.
- For fifth graders, the relationship between knowledge of connectives and English text comprehension was higher for English‐only students than for their peers who learned English as a second language.
- The present study found that knowledge of connectives also has a unique relation with Dutch expository text comprehension for eighth graders above and beyond reading fluency, general vocabulary knowledge and metacognitive knowledge (about text structure and reading and writing strategies).
- The relationship between knowledge of connectives and text comprehension was not moderated by reading fluency, general vocabulary knowledge and language background (monolingual versus bilingual Dutch).
- Metacognitive knowledge did impact the relationship between knowledge of connectives and text comprehension: the higher the metacognitive knowledge, the higher the association between knowledge of connectives and text comprehension.
- Secondary school readers are assumed to benefit from knowing connectives because these words are frequent in expository texts and signal relationships that students may often not infer without the help of these devices (i.e., with the use of background knowledge). This seems to apply in particular for expository texts that are intended to convey new information and relationships to students (see also Singer & O'Connell, 2003 ).
- We found a significant interaction between knowledge of connectives and metacognitive knowledge, which seems to indicate that knowing more connectives does not help much in improving expository text comprehension when metacognitive knowledge about text structure and reading strategies is low. This result suggests that it may be wise to couple instruction on the meaning of connectives with instruction about the structure of expository texts and ways to strategically deal with these texts.
- More specifically, besides instruction on the meaning of connectives, we advise teachers in secondary school to get students to understand the importance of connectives as markers of local and global coherence in texts, and to teach them how to strategically use connectives during reading.

This article discusses the lingering problem of poor and inappropriate preparation of professional teachers of reading and learning disabilities – why it exists and what we can do about it. Because most students classified as having learning disabilities experience primary difficulties with language-based learning, teachers must know how to teach the forms and processes of language on which literacy depends, but most teacher preparation programs fail to teach this content at a level that supports teachers' implementation of effective instruction. The evidence suggests that teachers may cling to unproductive philosophies of teaching not only because science-based instruction is neglected in many teacher training programs, but also because the requisite insights are elusive and the content is difficult for many to grasp, even with some exposure. While ideologies can be blamed for much resistance to explicit, systematic methodologies, we must ask why they develop in the first place. Although there is a substantial body of research on the relationship between teacher knowledge, practice, and student outcomes in reading on which to build reform in teacher training and mentoring, more thought should be given to how prospective teachers are taught. First, the disciplinary knowledge base required to teach students with reading and related difficulties must be unambiguously explained in the standards by which teachers are educated and evaluated, and then programs must be set up to build teachers' insight as well as their knowledge of basic reading psychology, language structure, and pedagogy. Those who teach teachers in university settings or who provide professional development must be included in a supportive educational process, as wars of ideology are having only limited positive effects. 相似文献

There has been a considerable suggestion in the literature that syntactic adaptation of a text would simplify it. This empirical study determined that the complexity of the syntax does not significantly affect the level of reading comprehension. While a complete conceptual and lexical analysis may be necessary for reading comprehension, a thorough syntactic analysis is not. This should be true for both expert and novice readers in a particular professional field, herein computer science. Using American (L1 or E1, English as a native language) and Dutch (L2 or E2, English as a second, nonnative language) computer science and humanities majors reading in EST (English for Science and Technology), it was found that there were no significant differences between subgroups reading an authentic (in original, unadapted form) computer science text and those reading a syntactically adapted text either in comprehension or in time across the four groups of subjects. These results indicate that syntactic simplification of an EST text is not a real simplification. Hence, technical writers and EST teachers might give priority to other more conceptual ways of rewriting texts. 相似文献
