Drawing on the Documents Model Framework, in two studies we investigate the types of multiple text models (e.g., mush model, separate representations model, documents model) reflected in students’ written responses, composed based on multiple texts. In among the first studies to holistically code written responses for the type of multiple text models they reflect, we find evidence for all of the multiple text representations specified in the Documents Model. We further examine the types of integration, or cross-textual connections, featured in students’ responses, including evidentiary (i.e., corroborating evidence), thematic (i.e., comparing main ideas across texts), and contextual (i.e., comparing meta-textual information, like author expertise) connections. Finally, we associate the types of multiple text models reflected in students’ written responses with various measures of integration, including the number of discourse connectives and citations included and self-reports of strategy use (Study 1), as well as with integrative utterances reported during a cued think-aloud (Study 2).  相似文献

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

In response to calls for research into effective instruction in the Earth and space sciences, and to identify directions for future research, this systematic review of the literature explores research into instructional approaches designed to facilitate conceptual change. In total, 52 studies were identified and analyzed. Analysis focused on the general characteristics of the research, the conceptual change instructional approaches that were used, and the methods employed to evaluate the effectiveness of these approaches. The findings of this review support four assertions about the existing research: (1) astronomical phenomena have received greater attention than geological phenomena; (2) most studies have viewed conceptual change from a cognitive perspective only; (3) data about conceptual change were generated pre- and post-intervention only; and (4) the interventions reviewed presented limited opportunities to involve students in the construction and manipulation of multiple representations of the phenomenon being investigated. Based upon these assertions, the authors recommend that new research in the Earth and space science disciplines challenges traditional notions of conceptual change by exploring the role of affective variables on learning, focuses on the learning of geological phenomena through the construction of multiple representations, and employs qualitative data collection throughout the implementation of an instructional approach.  相似文献

Set against the backdrop of reinvigorating the study of literature and concerns about the adequate preparation of students for the world of work, this paper explores how a Singapore teacher presented a literary text in the classroom. Drawing on data from a large-scale representative sample of Singapore schools in instruction and assessment practices, we discuss some of the potential consequences of instructional choice-making from a disciplinary perspective. Our findings suggest, for example, that when teacher-dominated discourse and interpretations dominate, instructional flexibility and responsiveness are correspondingly limited and restricted. These courses of action, we contend, may occur contrary to teachers’ plans and expectations. The paper closes by making a call for further longitudinal research across multiple research sites into the nature of literature pedagogy that has a strong disciplinary focus.  相似文献

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.  相似文献

This study examined patterns of change in beliefs and practices as elementary teachers learned to establish instructional congruence, a process of mediating academic disciplines with linguistic and cultural experiences of diverse student groups. The study focused on six bilingual Hispanic teachers working with fourth‐grade, mostly Hispanic students. The results indicated that teacher learning and change occurred in different ways in the areas of science instruction, students' language and culture, English language and literacy instruction, and integration of these areas in establishing instructional congruence. The results also indicated that establishing instructional congruence was a gradual and demanding process requiring teacher reflection and insight, formal training, and extensive support and sharing. Implications for further research in promoting achievement for all students are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 41: 65–93, 2004  相似文献

The Common Core State Standards and the continued inclusion of students with learning disabilities (LD) in Tier 1 classrooms are changing how close reading of texts occurs in English Language Arts classrooms. Therefore, understanding the potential impact of literacy‐related evidence‐based practices during Tier 1 instruction that includes students with reading‐related disabilities is essential. This article reviews the research on story‐structure instruction for students with LD and at‐risk for failure. Findings across 16 studies indicate several features of strong methodological designs including random assignment and inclusion of students with LD. However, substantial limitations in the research base include contradictory outcomes, limited outcomes disaggregated for students with LD, reliance on researcher‐developed measures, a lack of instructional features to support students with LD, and limited features of feasible implementation.  相似文献

Two studies were conducted to investigate the effects of cooperative learning on second‐graders’ motivation and learning from text. In Study 1, students (n = 160) in cooperative learning groups were compared with their counterparts (n = 107) in traditional instruction groups. The results revealed a statistically significant difference between the two groups, with more favourable perceptions of teachers’ instructional practices and better reading comprehension in the instructional intervention groups than in the traditional instruction groups. In Study 2, 51 second‐graders participated in the instructional intervention programme. The results showed that students’ positive cooperative behaviour and attitudes were related to their motivation and reading comprehension. When students perceived that their peers were willing to help each other and were committed to the group, they tended to be more motivated and performed better in reading comprehension.  相似文献

Prompted by the advent of new standards for increased text complexity in elementary classrooms in the USA, the current integrative review investigates the relationships between the level of text difficulty and elementary students’ reading fluency and reading comprehension. After application of content and methodological criteria, a total of 26 research studies were reviewed. Characteristics of the reviewed studies are reported including the different conceptualizations of text, reader, and task interactions. Regarding the relationships between text difficulty and reading fluency and comprehension, for students’ reading fluency, on average, increased text difficulty level was related to decreased reading fluency, with a small number of exceptions. For comprehension, on average, text difficulty level was negatively related to reading comprehension, although a few studies found no relationship. Text difficulty was widely conceptualized across studies and included characteristics particular to texts as well as relationships between readers and texts. Implications for theory, policy, curriculum, and instruction are discussed.  相似文献

To optimize students’ learning outcomes, educators are increasingly expected to use instructional practices shown to be effective by credible research. To help make this possible, organizations and scholars are producing resources that summarize research related to various instructional practices. However, as the collection of resources grows in size and complexity, it can be difficult and frustrating for practitioners to locate and utilize this information. In this article, we describe the 6S Pyramid (DiCenso, Bayley, & Haynes, 2009), a framework for efficiently and accurately prioritizing different types of research evidence. We also identify and briefly summarize Internet resources corresponding with each level of the Pyramid that can be used to identify research‐based practices for students with learning disabilities. To illustrate how the 6S Pyramid can be used in school and classroom settings, we begin and end the article with vignettes featuring a pair of co‐teachers seeking to improve instruction for their students who struggle with reading.  相似文献

Understanding bonding is fundamental to success in chemistry. A number of alternative conceptions related to chemical bonding have been reported in the literature. Research suggests that many alternative conceptions held by chemistry students result from previous teaching; if teachers are explicit in the use of representations and explain their content-specific forms and functions, this might be avoided. The development of an understanding of and ability to use multiple representations is crucial to students’ understanding of chemical bonding. This paper draws on data from a larger study involving two Year 11 chemistry classes (n = 27, n = 22). It explores the contribution of explicit instruction about multiple representations to students’ understanding and representation of chemical bonding. The instructional strategies were documented using audio-recordings and the teacher-researcher’s reflection journal. Pre-test–post-test comparisons showed an improvement in conceptual understanding and representational competence. Analysis of the students’ texts provided further evidence of the students’ ability to use multiple representations to explain macroscopic phenomena on the molecular level. The findings suggest that explicit instruction about representational form and function contributes to the enhancement of representational competence and conceptual understanding of bonding in chemistry. However, the scaffolding strategies employed by the teacher play an important role in the learning process. This research has implications for professional development enhancing teachers’ approaches to these aspects of instruction around chemical bonding.  相似文献

Teachers’ attitudes, motivation and self-efficacy are aspects of their professional competence affecting students’ motivation and learning via instructional behavior. In the present study, school type-specific differences in these teacher competencies and their relation to instruction when teaching with texts and integrated pictures are analyzed, further focusing on effects of school subject and teaching experience. Teachers (N?=?265) of primary school, lower and upper track secondary school filled in questionnaires. Primary school teachers were less intrinsically motivated to teach text-picture integration than secondary school teachers. They showed more negative attitudes towards texts with pictures than upper track teachers and avoided discussing the picture to a higher degree. All teacher characteristics predicted instructional behavior, further school type-specific effects of the subject occurred. The results provide starting points for teacher training and the potential for further research concerning the support of students in class.  相似文献

Whether through the use of online-only or hybrid/blended formats, colleges and universities across the country are increasingly utilizing online platforms as a medium for the delivery of instruction. At the same time, we know little about how student learning outcomes are related to students’ engagement with online instructional formats. In particular, few studies have evaluated online learning in community colleges, and fewer yet have employed an experimental or quasi-experimental design to do so. In this research, we use propensity score matching to compare learning gains between community college students enrolled in blended courses, (courses that combine online instructional delivery with traditional classroom-based instruction) with gains experienced by students receiving only classroom-based instruction. Among students enrolled in blended courses, we also consider which aspects of student use of online instructional materials are most strongly associated with student learning. While some evidence has suggested significantly poorer outcomes for community college students enrolled in online-only courses, our results suggest that students enrolled in blended courses perform similarly, if not better, relative to students in a traditional instructional setting. Implications for practice and research are discussed.  相似文献

Today virtual world instruction faces many of the same educational challenges faced by Web-based instruction during its infancy. There is a lot of jargon and visions of the future being bandied about, but as Hirumi et al. note in the May/June and July/August 2010 issues of TechTrends there little understanding of how to apply pedagogical practices in video game settings. i-MMOLE is a research-based instructional design framework created specifically for designing instruction that incorporates virtual world environments. To date, i-MMOLE has been utilized by university students in the creation of more than 300 lesson plans across multiple disciplines and age groups. This article describes the underlying foundation of this framework and how to utilize i-MMOLE in the creation of one’s own virtual world based instruction.  相似文献

This qualitative investigation explored the beliefs and practices of one secondary science teacher, Diane, who differentiated instruction and studied how technology facilitated her differentiation. Diane was selected based on the results of a previous study, in which data indicated that Diane understood how to design and implement proactively planned, flexible, engaging instructional activities in response to students’ learning needs better than the other study participants. Data for the present study included 3 h of semi-structured interview responses, 37.5 h of observations of science instruction, and other artifacts such as instructional materials. This variety of data allowed for triangulation of the evidence. Data were analyzed using a constant comparative approach. Results indicated that technology played an integral role in Diane’s planning and implementation of differentiated science lessons. The technology-enhanced differentiated lessons employed by Diane typically attended to students’ different learning profiles or interest through modification of process or product. This study provides practical strategies for science teachers beginning to differentiate instruction, and recommendations for science teacher educators and school and district administrators. Future research should explore student outcomes, supports for effective formative assessment, and technology-enhanced readiness differentiation among secondary science teachers.  相似文献

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in which students use science practices as they build and apply disciplinary core ideas. We report findings from a research study on professional development (PD) to support instructional leaders' learning about the science practices. After participating in the PD, the instructional leaders' familiarity with and leadership content knowledge of the science practices significantly improved. Initially, principals used their understandings from other disciplines and content neutral visions of classrooms to make sense of science instruction. For example, they initially used their understandings of models and argument from ELA and math to make sense of science classroom instruction. Furthermore, some principals focused on content neutral strategies, like a clear objective. Over the course of the PD workshops, principals took up the language of the science practices in more nuanced and sophisticated ways. Principals' use of the language of the science practices became more frequent and shifted from identifying or defining them to considering quality and implementation in science classrooms. As we design tools to support science, we need to consider instructional leaders as important stakeholders and develop resources to specifically meet their needs. If the science feels too unfamiliar or intimidating, principals may avoid or reframe science reform efforts. Consequently, it is important to leverage instructional leaders' resources from other disciplines and content neutral strategies as bridges for building understanding in science. We argue that the science practices are one potential lever to engage in this work and shift instructional leaders' understandings of science instruction.  相似文献

To enhance the basal vocabulary instruction for kindergarten students at risk for reading difficulties, lessons provided in typical curricular materials can be supplemented with instructional elements derived from research. This article addresses how teachers can add 15 minutes of higher order instructional activities to daily reading lessons to deepen students’ understanding of target vocabulary and offer multiple exposures to the words in different contexts. This enhanced basal vocabulary instruction model was field tested in two configurations of the kindergarten reading block to refine the procedures. These experiences provide insights into how the model can feasibly be implemented in small‐ or whole‐group formats to improve students’ learning and engagement.  相似文献

ABSTRACT

This research draws on a longitudinal study in which middle school math and science teachers enacted STEAM (science, technology, engineering, art and mathematics) teaching in their classroom after participating in intensive STEAM professional development aimed at increasing effective STEAM teaching. The authors address one important aspect in STEAM teaching, technology integration practices of teachers during instruction, and theorise their work using connected learning theory. Qualitative case study is used to identify and describe technology integration themes which emerged during STEAM instruction. Results suggest 17 of the 21 teachers participating in the study demonstrated technology integration involving one or more areas of instructional approaches, assessment and student use. The research expands what we know about how technology can be integrated in STEAM instruction and suggests ways to capitalise on technology to broaden access and appeal to all students during STEAM instruction.  相似文献
