Increasingly, researchers in the learning sciences are appealing to notions of community to shape the design of learning technologies and curricular innovations. Many of these designs, including those in the area of project-based science, show strong promise; but, it is a challenging matter to understand the influences of these innovations in a detailed enough fashion to refine them over time. This work demands sensitive, theoretically grounded ways to assess the depth to which particular facets of innovations help enculturate students into communities of discourse and practice. Taking genre theory and the sociology of science as points of departure, I demonstrate a unique approach to the problems of developing and assessing students' understanding of persuasive practices in the scientific community. The research I discuss revolves around students' use of a professional scientific genre of scientific writing, the Research Article or Introduction, Methods, Results, Discission (IMRD) report (Swales, 1990), as they compose reports about their own original research. Using data from an innovative project-based high school science class, I demonstrate how genre use provides a window on the effectiveness of a learning environment in helping use discipline-specific tools of persuasion. In the classroom studied here, students developed e-mail mentoring relationships with volunteer scientists across the United States and Canada. Working in partnership with the teacher, these "telementors" served not only as inquiry guides for students, but also as a critical audience that helped shape the arguments they made about their research. Detailed analysis of the final reports produced by teams of students in the class revealed a significant relation between their fulfillment of the customary persuasive functions of a scientific research article and sustained correspondence with their telementors. A significant relation was also observed between sustained dialogue with telementors and careful hedging of knowledge claims. I situate these findings within a body of theory that suggests the value of telementoring relationships consists not only the ongoing advice and guidance they furnish, but in the ways that a professional audience shapes students' ideas about the sorts of arguments that are called for in science class. Because the analysis of genre use is a relatively noninvasive way to examine students' understandings of scientific persuasion (as compared with survey instruments or pull-out interviews), this method can serve as a useful tool for reformers wishing to compare the outcomes from iterations or conditions of design experiments that aim to develop students' understanding of persuasive practices in the scientific community. It may also make a useful transfer measure for a wide range of classroom innovations that aim to cultivate scientific reasoning and persuasion, such as science-oriented tools for computer-supported collaborative learning. 相似文献

Instructional practices in secondary science: How teachers achieve local and standards-based success

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success. 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

In the study described in this article a questionnaire was employed that can be used to assess students' and teachers' perceptions of science teachers' interpersonal communication behaviors in their classroom learning environments. The Teacher Communication Behavior Questionnaire (TCBQ) has five scales: Challenging, Encouragement and Praise, Non‐Verbal Support, Understanding and Friendly, and Controlling. The TCBQ was used with a large sample of secondary science students in Taiwan, which provided additional validation data for the TCBQ for use in Taiwan and cross‐validation data for its use in English‐speaking countries. Girls perceived their teachers as more understanding and friendly than did boys, and teachers in biological science classrooms exhibited more favorable behavior toward their students than did those in physical science classrooms. Differences were also noted between the perceptions of the students and their teachers. Positive relationships were found between students' perceptions of their teachers' communication behaviors and their attitudes toward science. Students' cognitive achievement scores were higher when students perceived their teacher as using more challenging questions, as giving more nonverbal support, and as being more understanding and friendly. The development of both teacher and student versions of the TCBQ enhances the possibility of the use of the instrument by teachers. © 2002 John Wiley & Sons, Inc. J Res Sci Teach 39: 63–78, 2002 相似文献

We came to this study with a set of beliefs about good science teaching that had been heavily influenced by the constructivist literature of the past decade. In this article we reexamine some of our own assumptions about good teaching by exploring the classroom practices of an experienced physics teacher. This teacher did not fit the mold of the constructivist teacher and, yet, there was much to suggest that he was meeting the needs of the students in his class. His methods were almost entirely whole class—focusing mainly on physics content, examination technique and algorithm practice. Our close observation of this teacher in his Grade 11 classroom over several months suggests an alternative framework for examining his work. We examine this framework through a number of themes: teacher confidence, the structure of the discipline, student motivation, trust, and the cultural context of learning. We argue for a broader view of good science teaching than that proposed by the constructivist literature, one that takes into account teachers' and students' understandings of science in relation to their social and cultural contexts. 相似文献

Science includes more than just concepts and facts, but also encompasses scientific ways of thinking and reasoning. Students' cultural and linguistic backgrounds influence the knowledge they bring to the classroom, which impacts their degree of comfort with scientific practices. Consequently, the goal of this study was to investigate 5th grade students' views of explanation, argument, and evidence across three contexts—what scientists do, what happens in science classrooms, and what happens in everyday life. The study also focused on how students' abilities to engage in one practice, argumentation, changed over the school year. Multiple data sources were analyzed: pre‐ and post‐student interviews, videotapes of classroom instruction, and student writing. The results from the beginning of the school year suggest that students' views of explanation, argument, and evidence, varied across the three contexts with students most likely to respond “I don't know” when talking about their science classroom. Students had resources to draw from both in their everyday knowledge and knowledge of scientists, but were unclear how to use those resources in their science classroom. Students' understandings of explanation, argument, and evidence for scientists and for science class changed over the course of the school year, while their everyday meanings remained more constant. This suggests that instruction can support students in developing stronger understanding of these scientific practices, while still maintaining distinct understandings for their everyday lives. Finally, the students wrote stronger scientific arguments by the end of the school year in terms of the structure of an argument, though the accuracy, appropriateness, and sufficiency of the arguments varied depending on the specific learning or assessment task. This indicates that elementary students are able to write scientific arguments, yet they need support to apply this practice to new and more complex contexts and content areas. © 2011 Wiley Periodicals, Inc.

《Assessing Writing》1998,5(1):39-70
The Maryland School Performance Assessment Program (MSPAP) tests include an expressive writing task in which students at grades 3, 5, and 8 can choose to write about any topic they wish in the form of either a story, poem, or play. This test design feature provided the opportunity to investigate what factors contribute to students' choice of genre, how scorers apply a single expressive writing rubric to a range of genres, and whether these genres constitute equivalent tasks for measurement and reporting purposes. Our study, which combined analysis of statewide score data, 300 randomly selected student texts, questionnaires given to teacher-scorers, and interviews with students, argues strongly for the validity of this choice task as a measure of expressive writing and demonstrates that choice of genre both increases writers' engagement and enhances the fairness of the assessment by giving all students the best opportunity to demonstrate proficiency in this learning outcome. By highlighting several features of student texts that complicate scoring, the study also suggests that accuracy and consistency might be improved by
- 1.1) providing additional sample papers during training,
- 2.2) attending to scorers' assumptions regarding several key concepts, especially “originality,” and
- 3.3) adjusting the ways that training for focused holistic scoring generally takes place.

An examination was made concerning the relationships between Sudanese secondary science teachers' pupil control ideology and their students' perceptions/observations of the psychosocial environment of their science classrooms. One hundred secondary science teachers were classified as possessing humanistic (N = 20) or custodial (N = 20) control ideologies. A class (N = 40) of students was randomly selected for every teacher in both groups. The findings revealed that no significant relationships existed between the control ideologies of the teachers and their students' perceptions/observations of the classroom environment. Custodialism in control ideology was significantly related to the classroom environment psychosocial aspect of low “support.” Discussion and implications of the findings have been approached from both Sudanese and American perspectives. 相似文献

Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to understand the ways in which students' thinking can be maintained throughout the trajectory of science lessons. Past research in this area tends to foreground either the curriculum or teachers' practices. We propose a more comprehensive view of science instruction, one that requires attention to teachers' practice, the instructional task, and students' engagement. In this study, by examining the implementation of the same lesson across three different classrooms, our analysis of classroom videos and artifacts of students' work revealed how the interaction of teachers' practices, students' intellectual engagement, and a cognitively demanding task together support rigorous instruction. Our analyses shed light on their interaction that shapes opportunities for students' thinking and sensemaking throughout the trajectory of a science lesson. The findings provide implications for ways to promote rigorous opportunities for students' learning in science classrooms. 相似文献

Summary This paper explores the roles of students supporting technology in elementary classrooms. Students' primary role in the classroom is not to support teachers, but with technology, teachers take advantage of support in many forms. This paper classifies the ways in which students were found to support technology in the classroom, taking advantage of their expertise to help the teacher and other students. In some cases, students' efforts provided positive benefits to the teacher and other students, and in other cases, the students' efforts caused more problems than they solved. 相似文献

A learning unit in earth science was taught to high school students, using a jigsaw-group mastery learning approach. The sample consisted of 73 students in the experimental group and 47 students who learned the topic in an individualized mastery learning approach. The study lasted 5 weeks. Pretests and posttests on academic achievement and affective outcomes were administered. Data were treated with an analysis of covariance. The results show that students of the experimental group achieved significantly higher on academic outcomes, both normative and objective scores. On the creative essay test, the differences in number of ideas and total essay score were not significant between the groups, although the mean scores for number of words were higher for the individualized mastery learning group. On the affective domain, jigsaw-group mastery learning students scored significantly higher on self-esteem, number of friends, and involvement in the classroom. No differences were found in cohesiveness, cooperation, competition, and attitudes toward the subject learned. The results are discussed through the evaluation and comparison of the two methods of instruction used in this study. The cooperative learning movement began in junior high schools as part of the desegregation process, aiming at facilitating positive ethnic relations and increasing academic achievement and social skills among diverse students (Aronson, Stephan, Sikes, Blaney, & Snapp, 1978; Sharan & Hertz-Lazarowitz, 1980; Slavin, 1980). However, elementary teachers quickly recognized the potential of cooperative methods, and such methods were adopted freely in elementary schools before becoming widespread on the junior and senior high level. It has only been during the past few years that application of cooperative learning has been studied extensively with these older students. Cooperative learning methods generally involve heterogeneous groups working together on tasks that are deliberately structured to provide specific assignments and individual contributions from each group member. Cognitive as well as social benefits are expected, as students clarify their own understanding and share their insights and ideas with each other as they interact within the group (Deutsch, 1949). Experiments in the science laboratory have always required students to work in groups of two to four, due to the constraints of experimental processes and limited equipment and sup- plies. Thus, science courses are a natural curriculum area for examining cooperative learning practices. Now that cooperative methods are being refined to develop particular capabilities in the students, science teachers need to examine ways of structuring specific tasks to achieve the academic, affective, and socialization goals for their students. Although most of the studies of cooperative learning in the high school science classroom have centered around the cognitive outcomes of achievement testing and process skills, affective and social outcomes are also significant with students of this age. But few studies in science classes have attempted to assess such aspects of students' progress. As part of a previous revision, the science faculty at the high school where this study was conducted developed an exemplary individualized mastery learning (1ML) program for teaching science. This program seemed to alleviate the severe motivational problems and the extreme individual differences among the students in this rural/bhe-collar community. Students learned to work independently on their science studies. They had almost no lectures and few large group activities. As they worked through their assignments, however, they were free to interdct with other students. Looking in on a typical class, one would see several clusters of two or three students working together, sometimes tutoring each other, sometimes just talking through an assignment. Yet at least half of the class members would be working all alone. The importance of the overall social setting in the classroom as it relates to learning (Bruner, 1986, p. 86) and the central function of social interaction as learning occurs (Vygotsky, 1978, p. 106) seemed to have been ignored. Therefore, group mastery learning (GML), a cooperative learning tech- nique, was suggested as an antithesis to IML for teaching science over short periods. The cooperative mode of instruction considers learning as a cognitive as well as a social process, where students interact with each other as well as the teacher. To bring the social dimension back to science classrooms, the researchers chose to imple- ment GML in Grades 1 I and 12. The goal of the study was to investigate the GML's impact of the method on the individual student's academic achievement, creativity, self-esteem, and number of friends and on the overall learning environment of the classrooms. The researchers were also concerned with the students' attitudes toward earth science, the course being taught at the time of the experiment. Both cognitive and affective outcomes for students who participated in the cooperative GML approach were compared with outcomes for students who studied the same topic in an IML approach. The study addressed a number of questions related to academic and nonacademic outcomes of the two methods of study. First, it sought to determine whether academic achievement of the students taught in the cooperative GML mode would be different from the achievement of students who learned in an individualized method. Second, it sought to determine whether gains or losses would be seen in nonacademic outcomes, such as classroom learning environment, social relations, and students' self-esteem experienced by the students. The results of this study may support more use of cooperative learning in high school science. 相似文献

This study investigates classroom organisation and interaction focusing on phases of activity. The detailed in-depth case study is based on video recordings of 1 science unit consisting of 11 lessons about biological evolution in a Swedish ninth-grade class (aged 15). The study illuminates the temporality of student participation as a fundamental and practical concern for the science teaching profession. Through multiple scale analysis an activity pattern and students' contrasting positions are identified. Movements of control and agency between teacher and students in small-groups provide opportunities for the teacher to coordinate the teaching and the pace of students' participation. The implications point to challenges involved in providing all students with the learning opportunities that participation in the school science discourse affords. 相似文献

In this paper, I analyze teacher and student roles in the teaching and learning of science at an informal learning center,
The Outdoor Classroom. As a white middle class informal learning science teacher, I examine my struggles to teach science
to students across boundaries of race, class, gender, and experience with the outdoors during field trips. Through the field
trip I did not have the time or face-to-face experience to make sense of the students’ culture, see their culture in terms
of capital, and align my enactment to benefit their learning. Likewise, the students did not have the time or face-to-face
experience with me in order to adapt their cultural capital and build the essential stocks of symbolic and social capital.
This research demonstrates how the classroom teacher draws upon previous transactions and emotions to successfully engage
her students in practices that promote the participation and learning of science. Through creating culturally adaptive ways
of transacting, teachers can provide opportunities for their students to generate positive emotional energy and group solidarity
in the learning of science at an informal science center. 相似文献

We present an analysis of students' reflective writing (diaries) of two cohorts of Grade 8 students, one undergoing inquiry and the other traditional science teaching. Students' writing included a summary of what students had learned in class on that day and their opinions and feelings about the class. The entries were analysed qualitatively and quantitatively. This analysis of students' first-person accounts of their learning experience and their notes taken during class was useful in two ways. First, it brought out a spectrum of differences in outcomes of these two teaching modes—conceptual, affective and epistemic. Second, this analysis brought out the significance and meaning of the learning experience for students in their own words, thus adding another dimension to researchers' characterisation of the two teaching methods. 相似文献

Recent research reveals that students' interest in school science begins to decline at an early age. As this lack of interest could result in fewer individuals qualified for scientific careers and a population unprepared to engage with scientific societal issues, it is imperative to investigate ways in which interest in school science can be increased. Studies have suggested that inquiry learning is one way to increase interest in science. Inquiry learning forms the core of the primary syllabus in Singapore; as such, we examine how inquiry practices may shape students' perceptions of science and school science. This study investigates how classroom inquiry activities relate to students' interest in school science. Data were collected from 425 grade 4 students who responded to a questionnaire and 27 students who participated in follow-up focus group interviews conducted in 14 classrooms in Singapore. Results indicate that students have a high interest in science class. Additionally, self-efficacy and leisure-time science activities, but not gender, were significantly associated with an increased interest in school science. Interestingly, while hands-on activities are viewed as fun and interesting, connecting learning to real-life and discussing ideas with their peers had a greater relation to student interest in school science. These findings suggest that inquiry learning can increase Singaporean students' interest in school science; however, simply engaging students in hands-on activities is insufficient. Instead, student interest may be increased by ensuring that classroom activities emphasize the everyday applications of science and allow for peer discussion. 相似文献

This article explores practices of othering through formations of normative sameness in discussion-based seminar classrooms. It takes literary scholar Stanley Fish's question, ‘Is there a text in this class, or is it just us?’, back into the classroom to explore the formation of a ‘just us,’ an imagined homogeneous interpretive community which, I argue, has discriminatory effects by normalising some voices and practices. It draws on feminist and anti-oppressive theory to discuss ways to pedagogically trouble the enactment of homogeneous interpretive communities in the Gender Studies classroom. As the Gender Studies teacher, I devised pedagogical practices based on the allocation of specific roles as a way to work towards an anti-discriminatory classroom by de-mystifying academic practice and framing seminar practice as a social genre. The article critically reflects on students' subsequent reluctance to take on roles and their preference for free-flowing discussions, doing what comes naturally, a ‘doing' of academia which, I suggest, is linked to social privilege. 相似文献

This article examines classroom practices that draw upon students' understandings of race and equity as they engage in critical literature inquiry to explore issues of power in our society. Our research team, comprising a fifth-grade classroom teacher, a doctoral candidate, and a university professor, analyzed students' written and digital projects to better understand what new skills, strategies, and meaning-making opportunities emerge when race is centralized in the curriculum. We documented the various ways students were able to voice their thoughts through multimodal learning in an elementary language arts classroom. 相似文献

Teaching science as explanation is fundamental to reform efforts but is challenging for teachers—especially new elementary teachers, for whom the complexities of teaching are compounded by high demands and little classroom experience. Despite these challenges, few studies have characterized the knowledge, beliefs, and instructional practices that support or hinder teachers from engaging their students in building explanations. To address this gap, this study describes the understandings, purposes, goals, practices, and struggles of one third-year elementary teacher with regard to fostering students' explanation construction. Analyses showed that the teacher had multiple understandings of scientific explanations, believed that fostering students' explanations was important for both teachers and students, and enacted instructional practices that provided opportunities for students to develop explanations. However, she did not consistently take up explanation as a goal in her practice, in part because she did not see explanation construction as a strategy for facilitating the development of students' content knowledge or as an educational goal in its own right. These findings inform the field's understanding of teacher knowledge and practice with regard to one crucial scientific practice and have implications for research on teachers and inquiry-oriented science teaching, science teacher education, and curriculum materials development. 相似文献

Teacher expectations are associated with student academic achievement, but no research has generated new theory that explains how teacher expectation effects occur from students' perspectives. A substantive theory explaining the process through which students reconcile with their teachers' expectations is presented in this paper, emphasising the role of caring student-teacher relationships in teacher expectation effects on academic achievement. The theory was constructed with 25 grade 10 participants across three Western Australian secondary schools, with data including 100 interviews and 175 classroom observations. The analysis and synthesis of the data confirmed that the students acted in ways that they reflected improved their academic attainment when their teachers communicated high expectations of them. Noddings' enduring philosophy of the ‘ethic of care’ is used as a discussion framework, emphasising implications for how teachers practise and learn to interact with their students so that they can initiate positive teacher expectation effects on student learning. 相似文献

A considerable body of evidence highlights how inquiry-based science can enhance students' epistemic and conceptual understanding of scientific concepts, principles, and theories. However, little is known about how students view themselves as learners of science. In this paper, we explore primary children's images of doing science in school and how they compare themselves with ‘real’ scientists. Data were collected through the use of a questionnaire, drawing activity, and interviews from 161 Grade 4 (ages 9–10) students in Singapore. Results indicate that ‘doing science as conducting hands-on investigations’, ‘doing science as learning from the teacher’, ‘doing science as completing the workbook’, and ‘doing science as a social process’ are the images of learning science in school that most of the students held. In addition, students reported that they need to be well behaved first and foremost, while scientists are more likely to work alone and do things that are dangerous. Moreover, students often viewed themselves as ‘acting like a scientist’ in class, especially when they were doing experiments. Nevertheless, some students reported that they were unlike a scientist because they believed that scientists work alone with dangerous experiments and do not need to listen to the teacher and complete the workbook. These research findings further confirm the earlier argument that young children can make distinctions between school science and ‘real’ science. This study suggests that the teaching of science as inquiry and by inquiry will shape how students view their classroom experiences and their attitudes towards science. 相似文献
