Student difficulties in science learning are frequently attributed to misconceptions about scientific concepts. We argue that domain‐general perceptual processes may also influence students' ability to learn and demonstrate mastery of difficult science concepts. Using the concept of center of gravity (CoG), we show how student difficulty in applying CoG to an object such as a baseball bat can be accounted for, at least in part, by general principles of perception (i.e., not exclusively physics‐based) that make perceiving the CoG of some objects more difficult than others. In particular, it is perceptually difficult to locate the CoG of objects with asymmetric‐extended properties. The basic perceptual features of objects must be taken into account when assessing students' classroom performance and developing effective science, technology, engineering, and mathematics (STEM) teaching methods. 相似文献

For students to meaningfully engage in science practices, substantive changes need to occur to deeply entrenched instructional approaches, particularly those related to classroom discourse. Because teachers are critical in establishing how students are permitted to interact in the classroom, it is imperative to examine their role in fostering learning environments in which students carry out science practices. This study explores how teachers describe, or frame, expectations for classroom discussions pertaining to the science practice of argumentation. Specifically, we use the theoretical lens of a participation framework to examine how teachers emphasize particular actions and goals for their students' argumentation. Multiple-case study methodology was used to explore the relationship between two middle school teachers' framing for argumentation, and their students' engagement in an argumentation discussion. Findings revealed that, through talk moves and physical actions, both teachers emphasized the importance of students driving the argumentation and interacting with peers, resulting in students engaging in various types of dialogic interactions. However, variation in the two teachers' language highlighted different purposes for students to do so. One teacher explained that through these interactions, students could learn from peers, which could result in each individual student revising their original argument. The other teacher articulated that by working with peers and sharing ideas, classroom members would develop a communal understanding. These distinct goals aligned with different patterns in students' argumentation discussion, particularly in relation to students building on each other's ideas, which occurred more frequently in the classroom focused on communal understanding. The findings suggest the need to continue supporting teachers in developing and using rich instructional strategies to help students with dialogic interactions related to argumentation. This work also sheds light on the importance of how teachers frame the goals for student engagement in this science practice. 相似文献

The engagement model of reading development suggests that instruction improves students' reading comprehension to the extent that it increases students' engagement processes in reading. We compared how Concept‐Oriented Reading Instruction (CORI) (support for cognitive and motivational processes in reading), strategy instruction (support for cognitive strategies in reading), and traditional instruction in fourth‐grade classrooms differentially influenced students' reading comprehension, strategy use, and engagement in reading. Students experiencing CORI were significantly higher than both comparison groups on reading comprehension, reading strategies, and reading engagement. When students' level of reading engagement was statistically controlled, the differences between the treatment groups were not significant. We infer that the level of students' reading engagement during classroom work mediated the instructional effects on reading outcomes. © 2008 Wiley Periodicals, Inc. 相似文献

This paper reports the findings from a study of teachers and students' views regarding self‐worth in the primary school learning environment. The revised New Zealand curriculum recognises the importance of self‐worth in students' motivation and ability to learn. While the need to enhance self‐worth in the classroom has been well established in the literature, similarities and differences between teachers and students' understanding of the impact of various classroom interactions on self‐worth has not received the same attention. The purpose of the research reported on in this paper was to provide further insight for teachers, thereby enabling them to strengthen classroom relationships and their students' learning experiences in ways commensurate with enhancing students' feelings of self‐worth. 相似文献

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case‐study design and qualitative data‐collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5‐ and 6‐year‐old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5‐week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment. © 2004 Wiley Periodicals, Inc.

We set out to understand how different instantiations of inquiry emerged in two different years of one elementary teacher's classroom. Longitudinal observations from Mrs. Charles' 5th grade science classroom forced us to carefully and deliberately consider who exactly was responsible for the change in the class activities and norms. We provide empirical evidence to show how a focus on the teacher can easily overlook the complex dynamics of the classroom. The data reveal that students had a substantive and generative role in the class's arrival at the different instantiations of scientific inquiry—the nature and form of inquiry—that were constructed each year. We argue that, in an environment where a teacher carefully attends and responds to student thinking, the nascent resources students have for reasoning about phenomena can affect not only the conceptual ideas that emerge, but also influence what inquiry activities or practices become established as normative and productive over time. Our work with Mrs. Charles illuminates an important methodological concern with research on teacher development as well as the construct of teacher learning progressions; research accounts that focus primarily on the teacher may overlook the classroom norms that are negotiated between teacher and student, and thereby provide an incomplete portrayal of the teacher's activity within one classroom and the teacher's progress across multiple years. © 2012 Wiley Periodicals, Inc.

Understanding how cultural mediators and social interaction promote meaningful learning requires that each student's perspective, reasoning, and construction processes be taken into account. In my analysis of the classroom episodes, I consider individual students' progress as they use tools, discuss data distributions, and interact with their teachers and their peers. I argue that data display tools provide a partial context for discussions but do not constrain the students' interpretations or the way they reason about the data. Students' approaches to the mathematical relations discussed in the classroom result rather from the meaning they attribute to the different features of the displays, the teachers' questions, and the evolving interaction with their peers. 相似文献

The problem addressed in the study was whether 10‐ and 11‐year‐old children, collaborating within a computer‐supported classroom, could engage in progressive inquiry that exhibits an essential principal feature of mature scientific inquiry: namely, engagement in increasingly deep levels of explanation. Technical infrastructure for the study was provided by the Computer‐Supported Intentional Learning Environment (CSILE). The study was carried out by qualitatively analyzing written notes logged by 28 Grade 5/6 students to CSILE's database. Results of the study indicated that with teacher guidance, students were able to produce meaningful intuitive explanations about biological phenomena, guide this process by pursuing their own research questions, and engage in constructive peer interaction that helped them go beyond their intuitive explanations and toward theoretical scientific explanations. Expert evaluations by three widely recognized philosophers of science confirmed the progressive nature of students' inquiry. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 1072–1088, 2003 相似文献

The emergence of the incorporation of culture into EFL education is a growing trend in Taiwan. The purpose of the study was to examine: (1) the effects of the ethnographic interview project on Taiwanese students' cognitive development in understanding native English speakers and their cultures; (2) changes in students' self‐awareness and understanding of both the target culture and their own; and (3) students' perceptions of the ethnographic interview project employed in EFL college classes. Data were collected through pre–post questionnaires, oral and written reports, classroom observation and interviews. Results indicated that participation in the ethnographic interview project helped facilitate the development of cross‐cultural awareness and communication skills by providing opportunities for students to gain insight into the values of target language countries, learn to view their own culture in new ways, increase their confidence in using English to communicate and view authentic communication as the goal of EFL learning. The majority of the participants saw the ethnographic interview project as an effective means of facilitating intercultural/interpersonal communication and understanding. 相似文献

The purpose of this article is to report findings from an ethnographic study that focused on the co‐development of science literacy and academic identity formulation within a third‐grade classroom. Our theoretical framework draws from sociocultural theory and studies of scientific literacy. Through analysis of classroom discourse, we identified opportunities afforded students to learn specific scientific knowledge and practices during a series of science investigations. The results of this study suggest that the collective practice of the scientific conversations and activities that took place within this classroom enabled students to engage in the construction of communal science knowledge through multiple textual forms. By examining the ways in which students contributed to the construction of scientific understanding, and then by examining their performances within and across events, we present evidence of the co‐development of students' academic identities and scientific literacy. Students' communication and participation in science during the investigations enabled them to learn the structure of the discipline by identifying and engaging in scientific activities. The intersection of academic identities with the development of scientific literacy provides a basis for considering specific ways to achieve scientific literacy for all students. © 2004 Wiley Periodicals, Inc.

In recent years, research on students' scientific argumentation has progressed to a recognition of nascent resources: Students can and do argue when they experience the need and possibility of persuading others who may hold competing views. Our purpose in this article is to contribute to this progress by applying the perspective of framing to the question of when and how a class forms and maintains a sense of their activity as argumentative. In particular, we examine three snippets from a sixth‐grade class with respect to how the students—and the teacher—experience, or frame, what is taking place. We argue that they show dynamics of framing for individuals and for the class as a whole that affect and are affected by students' engagement in argumentation. We close the article with implications of this perspective for research, teaching, and instructional design. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 49: 68–94, 2012 相似文献

Recent curriculum design projects have attempted to engage students in authentic science learning experiences in which students engage in inquiry‐based research projects about questions of interest to them. Such a pedagogical and curricular approach seems an ideal space in which to construct what Lee and Fradd referred to as instructional congruence. It is, however, also a space in which the everyday language and literacy practices of young people intersect with the learning of scientific and classroom practices, thus suggesting that project‐based pedagogy has the potential for conflict or confusion. In this article, we explore the discursive demands of project‐based pedagogy for seventh‐grade students from non‐mainstream backgrounds as they enact established project curricula. We document competing Discourses in one project‐based classroom and illustrate how those Discourses conflict with one another through the various texts and forms of representation used in the classroom and curriculum. Possibilities are offered for reconstructing this classroom practice to build congruent third spaces in which the different Discourses and knowledges of the discipline, classroom, and students' lives are brought together to enhance science learning and scientific literacy. © 2001 John Wiley & Sons, Inc.

This teacher development study closely examined a teacher's practice for the purpose of understanding how she selected and implemented instructional materials, and correspondingly how these processes changed as she developed her problem‐based practice throughout a school year. Data sources included over 20 hours of planning and analysis meetings with the teacher and 27 video‐taped lessons with discussions before and after each lesson. Through qualitative analysis we examined the data for: students' cognitive demand for curricular materials the teacher selected and implemented; teacher's beliefs and practices for students' engagement in mathematical thinking; and teacher's and students' communication about mathematics during instruction. We found that the teacher shifted her views and use of instructional materials as she changed her practice towards more problem‐based approaches. The teacher moved from closely following her traditional, district‐adopted textbook to selecting problem‐based tasks from outside resources to build a curriculum. Simultaneously, she changed her practice to focus more on students' engagement in mathematical thinking and their communication about mathematics as part of learning. During this shift in practice, the teacher began to reify instructional materials, viewing them as instruments of her practice to meet students' needs. The process of shifting her views was gradual over the school year and involved substantial analysis and reflection on practice from the teacher. Implications include that teachers and teacher educators may need to devote more attention and support for teachers to use instructional materials to support instruction, rather than materials to prescribe instruction. This use of instructional materials may be an important part of transforming practice overall. 相似文献

Abstract This study examined how six Singapore teachers approached the design and implementation of a unit of work (topic) to demonstrate exemplary classroom practices that engage learners and use ICT in knowledge-generative rather than presentational activities. After a reflection and feedback session on the first lesson observation involving the researcher and the teacher, the teacher redesigned the lesson to enhance ICT use and involve students more actively in their learning. Our study revealed that there is a difference between students' physical engagement and cognitive engagement in a task and that the teacher, as a designer of the learning environment, needs to make explicit the cognitive processes involved in using the tool to ensure students' effective use of ICT. The teachers' understanding of what constitutes effective learning and their roles in students' learning determine how they design the learning environment. In essence, it is the teacher's skill in managing the “tripartite” partnership of IT tool, learning task, and teacher support that brings about higher levels of student engagement. 相似文献

The current study was carried out within the framework of self-determination theory and aimed to investigate specific, additive and combined effects of teachers' autonomy support and structure on students' engagement. Using multilevel analyses, main effects and interaction of autonomy support and structure provided at the classroom level were tested on behavioral, cognitive and emotional engagement. 744 ninth grade students from 51 classes completed a questionnaire about their engagement during language classes and their perceptions of the teacher's provision of autonomy support and structure. The results highlight the links between classroom context, especially structure, and the three components of engagement. Autonomy support has a complementary role as it was associated with emotional engagement. These results improve our understanding of the relationships between learning environment and engagement and provide more accurate indications to teachers and educators regarding the most effective ways to enhance students' engagement. 相似文献

In recent years, there has been a strong push to transform STEM education at K-12 and collegiate levels to help students learn to think like scientists. One aspect of this transformation involves redesigning instruction and curricula around fundamental scientific ideas that serve as conceptual scaffolds students can use to build cohesive knowledge structures. In this study, we investigated how students use mass balance reasoning as a conceptual scaffold to gain a deeper understanding of how matter moves through biological systems. Our aim was to lay the groundwork for a mass balance learning progression in physiology. We drew on a general models framework from biology and a covariational reasoning framework from math education to interpret students' mass balance ideas. We used a constant comparative method to identify students' reasoning patterns from 73 interviews conducted with undergraduate biology students. We helped validate the reasoning patterns identified with >8000 written responses collected from students at multiple institutions. From our analyses, we identified two related progress variables that describe key elements of students' performances: the first describes how students identify and use matter flows in biology phenomena; the second characterizes how students use net rate-of-change to predict how matter accumulates in, or disperses from, a compartment. We also present a case study of how we used our emerging mass balance learning progression to inform instructional practices to support students' mass balance reasoning. Our progress variables describe one way students engage in three dimensional learning by showing how student performances associated with the practice of mathematical thinking reveal their understanding of the core concept of matter flows as governed by the crosscutting concept of matter conservation. Though our work is situated in physiology, it extends previous work in climate change education and is applicable to other scientific fields, such as physics, engineering, and geochemistry. 相似文献

Student engagement in the design and implementation of inquiries is an effective way for them to learn about the inquiry process and the domain being studied. However, inquiry learning in geography can be challenging for teachers and students due to the complexity of scientific inquiry and the diversity of pupils' and teachers' knowledge and abilities. To address this, the Personal Inquiry project has designed a tool kit that includes nQuire, a Web-based tool to support students through the inquiry process. Here, we identify when, across five lessons comprising an inquiry into microclimates, nQuire was used by a teacher and a case study group of her 12 to 13-year-old students, and the ways in which they adopted nQuire as a tool to facilitate the creation of a coherent and cumulative inquiry learning experience over time. We found that students' use of nQuire supported them in capturing and representing their evolving understanding of inquiry, in defining and supporting their progression through the process of inquiry and in resourcing their cognitive engagement in data interpretation and representation. nQuire supported the students in accumulating and integrating new understandings across contexts and over time. In this way, nQuire successfully resourced and supported the students' learning journeys or trajectories. We conclude that nQuire can be an effective tool for supporting teachers' and students' understanding of the nature of inquiry and how to design and implement inquiries of their own. 相似文献

In this paper, we analyse interactions between secondary students and pre‐service teachers in an online environment in order to understand how their meaning‐making processes embody distributed cognition. We begin by providing a theoretical review of the ways in which literacy learning is distributed across learners, objects, tools, symbols, technologies and the environment in modern English language arts classrooms. This is followed by a case study where we identify how programme values, textual resources and cultural schema function as distributed tools. In traditional schools, with an emphasis on taking standardised tests, the learning environment is designed on the view that learning is a transaction that happens solely ‘inside the head’. Unfortunately, this pushes many students to the margins of classroom engagement and participation. By analysing students' and pre‐service teachers' online discourse, we argue that virtual spaces can facilitate critical dialogue and can act as catalysts for a distributed theory of mind. 相似文献

Toward implementing distributed scaffolding: Helping students learn science from design 总被引：1，自引：0，他引：1
In this article, we present two studies that helped us understand the kinds of support that students need to learn science successfully from design activities. Both were enacted in the context of an approach to learning science from design called learning by design (LBD). In our first study, we designed and integrated a paper‐and‐pencil scaffolding tool, the design diary, into an LBD unit to support students' design‐related activities. We learned two important lessons from the first study. First, we refined our understanding of the processes involved in designing and the ways we might present those processes to students. Second, and more important, we observed that in the dynamic, complex environment of the classroom, not all of the scaffolding could be provided with any one tool or agent. We found that students need multiple forms of support and multiple learning opportunities to learn science successfully from design activities. In our next study, we provided additional support through an organized system of tools and agents. Our analysis of data from the second study leads us to believe that supporting multiple students in a classroom requires us to rethink the notion of scaffolding as it applied to groups of learners in a classroom. We put forth the notion of distributed scaffolding as an approach to supporting hands‐on inquiry learning in a classroom. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 185–217, 2005 相似文献
