Environment and environmental protection are on the forefront of political concerns globally. But how are the media and political discourses concerning these issues mirrored in the public more generally and in the discourses of school science students more specifically? In this study, we analyze the discourse mobilized in whole-class conversations of and interviews with 15- to 16-year-old Swiss junior high school students. We identify two core interpretive repertoires (each unfolding into two second-order repertoires) that turn out to be the building blocks of environmental discourse, which is characteristic not only of these students but also of Swiss society more generally. The analysis of our students’ discourse demonstrates how their use of interpretive repertoires locks them in belief talk that they have no control over ecological issues, which can put them in the danger of falling prey to ecological passivity. As a consequence of our findings we suggest that teachers should be endorsed to interpret their teaching of environmental issues in terms of the enriching and enlarging of their students’ interpretive repertoires. 相似文献

Research into classroom interactions has shown that talk that promotes reasoning can help children in their learning of science. Such talk can only be generated when teachers are willing to take a dialogic approach that is stimulating and provides opportunities for children to articulate their ideas. This research set out to determine whether the use of large puppets would help teachers to change the nature of their whole class discourse to enhance children’s talk and engagement in science. The study was carried out with sixteen teachers of children aged 7–11 years in schools in London and Manchester, UK. Through adopting a mixture of research methods, including classroom observation and teacher and child interviews, the research provides evidence that the use of puppets significantly increases the amount of teacher discourse oriented towards reasoning and argument, and decreases the amount of talk that focuses on recall. Through the puppets, teachers also use more narrative to set the science in stimulating contexts, and encourage children in their contributions to whole class discussion. Interview data also show the positive effects of puppets on children’s motivation and engagement in science. The findings have led to further major funding for professional development in the use of puppets in the UK, and research into the reasons why the use of puppets is so effective. 相似文献

This paper explores the consequences of these discourses for the ways that international students are identified and positioned within school communities. My argument is developed in four sections. The first describes my ongoing exploration into the impact of international student programmes in Australia. The second exemplifies my argument: exploring the day‐to‐day experiences of vice principals in two Victorian government state secondary schools as they market their schools, and examining the systemic and ontological discourses played out within those conversations. The third interrogates discourses of identity and difference, neo‐liberalism and naïve cosmopolitanism which I find shape teacher conversations about international student programmes. In the final section, I argue that the impact of the discourse formations implicit in teacher talk about international student programmes has been the objectification of international students and their ambivalent inclusion within the school community. 相似文献

The first objective of this study was to investigate if the experimental students’ post‐test knowledge of nutrition and plant reproduction would be improved more significantly than that of their control group counterparts based on their treatment, attitudes to science, self‐esteem, gender and socio‐economic background. Treatment involved teaching the experimental students under three learning modes—pure cooperative, cooperative–competitive and individualistic whole class interpersonal competitive condition—using concept and vee mappings and the lecture method. The control groups received the same treatment but were not exposed to concept and vee mappings. This study’s second objective was to determine which of the three learning modes would produce the highest post‐test mean gain in the subjects’ knowledge of the two biology concepts. The study’s sample comprised 932 eighth graders (12–13‐year‐olds) in 14 co‐educational comprehensive high schools randomly selected from two Jamaican parishes. An integrated science performance test, an attitudes to science questionnaire and a self‐esteem questionnaire were used to collect data. The results indicated that the experimental students (a) under the three learning modes, (b) with high, moderate, and low attitudes to science, and (c) with high, moderate, and low self‐esteem, performed significantly better than their control group counterparts. The individualist whole class learning mode engendered the highest mean gain on the experimental students’ knowledge, while the cooperative–competitive learning mode generated the highest mean gain for the control group students. 相似文献

In this theoretical article we use an interpretative study with physics undergraduates to exemplify a proposed characterization of student learning in university science in terms of fluency in disciplinary discourse. Drawing on ideas from a number of different sources in the literature, we characterize what we call “disciplinary discourse” as the complex of representations, tools and activities of a discipline, describing how it can be seen as being made up of various “modes”. For university science, examples of these modes are: spoken and written language, mathematics, gesture, images (including pictures, graphs and diagrams), tools (such as experimental apparatus and measurement equipment), and activities (such as ways of working—both practice and praxis, analytical routines, actions, etc.). Using physics as an illustrative example, we discuss the relationship between the ways of knowing that constitute a discipline and the modes of disciplinary discourse used to represent this knowing. The data comes from stimulated recall interviews where physics undergraduates discuss their learning experiences during lectures. These interviews are used to anecdotally illustrate our proposed characterization of learning and its associated theoretical constructs. Students describe a repetitive practice aspect to their learning, which we suggest is necessary for achieving fluency in the various modes of disciplinary discourse. Here we found instances of discourse imitation, where students are seemingly fluent in one or more modes of disciplinary discourse without having related this to a teacher‐intended disciplinary way of knowing. The examples lead to the suggestion that fluency in a critical constellation of modes of disciplinary discourse may be a necessary (though not always sufficient) condition for gaining meaningful holistic access to disciplinary ways of knowing. One implication is that in order to be effective, science teachers need to know which modes are critical for an understanding of the material they wish to teach. © 2008 Wiley Periodicals, Inc.

This article examines how emergent bilingual students used gestures in science class, and the consequences of students’ gestures when their language repertoire limited their possibilities to express themselves. The study derived from observations in two science classes in Sweden. In the first class, 3rd grade students (9–10 years old) were involved in a unit concerning electricity. The second class consisted of 7th‐grade students (13–14 years old) working with acids and bases. Data were analyzed by using practical epistemological analysis (PEA). When students’ language proficiency limited their possibility to express themselves, using gestures resulted in the continuation of the science activities. Furthermore, both peers and teachers drew on the used gestures to talk about the science content. In some situations, the meaning of the gestures needed to be negotiated. Regardless, the gestures were always related to language. Both students and teachers participated in this process, but the teachers directed the communication toward the goal of the lessons: learning how to talk science. The study contributes to the field by showing the importance of paying attention to and valuing bilingual students’ use of gestures as a way to express scientific knowledge. In addition, it demonstrates how teachers might draw on students’ gestures to teach science and discusses the importance of creating multimodal learning environments. © 2017 Wiley Periodicals, Inc.

There is a growing interest in using classroom response systems or clickers in science classrooms at both the university and K-12 levels. Typically, when instructors use this technology, students are asked to answer and discuss clicker questions with their peers. The existing literature on using clickers at the K-12 level has largely focused on the efficacy of clicker implementation, with few studies investigating collaboration and discourse among students. To expand on this work, we investigated the question: Does clicker use promote productive peer discussion among middle school science students? Specifically, we collected data from middle school students in a physical science course. Students were asked to answer a clicker question individually, discuss the question with their peers, answer the same question again, and then subsequently answer a new matched-pair question individually. We audio recorded the peer conversations to characterize the nature of the student discourse. To analyze these conversations, we used a grounded analysis approach and drew on literature about collaborative knowledge co-construction. The analysis of the conversations revealed that middle school students talked about science content and collaboratively discussed ideas. Furthermore, the majority of conversations, both ones that positively and negatively impacted student performance, contained evidence of collaborative knowledge co-construction. 相似文献

Children's developing reasoning skills are better understood within the context of their social and cultural lives. As part of a research–museum partnership, this article reports a study exploring science‐relevant conversations of 82 families, with children between 3 and 11 years, while visiting a children's museum exhibit about mammoth bones, and in a focused one‐on‐one exploration of a “mystery object.” Parents' use of a variety of types of science talk predicted children's conceptual engagement in the exhibit, but interestingly, different types of parent talk predicted children's engagement depending on the order of the two activities. The findings illustrate the importance of studying children's thinking in real‐world contexts and inform creation of effective real‐world science experiences for children and families. 相似文献

We investigated the role of dissent in a community of university scientists, engineers, mathematicians, and social scientists engaged in a 2‐year professional development project around issues of equity and diversity. Members of this teacher learning community explored issues related to gender and ethnicity in science education, and attempted to develop course materials and instructional strategies inclusive of students from underrepresented groups. We focused our attention on those professional development sessions (6 of the 19) devoted to a contentious yet integral topic in science education: the gendered and multicultural nature of science. We examined conversations initiated by a member's concerns to learn how dissent led (or failed to lead) to new insights into feminist science studies scholarship or to greater understanding of ways to address equity issues in undergraduate science education. We also explored how teacher learners' resulting views of feminist science studies scholarship informed (or failed to inform) changes in their own educational practices. From our qualitative analyses, we highlight the challenges in balancing respect for members' individual voices with collective progress toward project goals, and in structuring conversations initiated by dissent to provide adequate space for deliberation and movement toward deeper understanding of equity and excellence. © 2002 Wiley Periodicals, Inc.

We describe how we used puppets as tools to draw 9 to 10‐year‐old students into conversations about probability. Puppets supported classroom discourse by putting forth probabilistic arguments for critique, introducing extreme and unusual examples of concepts, and introducing an element of surprise. 相似文献

We investigated how Chinese physics teachers structured classroom discourse to support the cognitive and social aspects of inquiry-based science learning. Regarding the cognitive aspect, we examined to what extent the cognitive processes underlying the scientific skills and the disciplinary reasoning behind the content knowledge were taught. Regarding the social aspect, we examined how classroom discourse supported student learning in terms of students' opportunities to talk and interaction patterns. Our participants were 17 physics teachers who were actively engaged in teacher education programs in universities and professional development programs in local school districts. We analyzed one lesson video from each participating teacher. The results suggest both promises and challenges. Regarding the cognitive aspect of inquiry, the teachers in general recognized the importance of teaching the cognitive processes and disciplinary reasoning. However, they were less likely to address common intuitive ideas about science concepts and principles. Regarding the social aspect of inquiry, the teachers frequently interacted with students in class. However, it appeared that facilitating conversations among students and prompting students to talk about their own ideas are challenging. We discuss the implications of these findings for teacher education programs and professional development programs in China. 相似文献

This study presents a comparison between how six teachers and their 17‐year‐old students talked about texts in civics and nursing science during regular lessons and during two lessons where structured text talk in smaller groups was used. The majority of students were poor readers and attended vocational programmes. The text talks were videotaped. During the regular lessons, most of the teachers asked purely factual questions where the students just had to retrieve information from the text to be able to answer them. The students made few inferences and reflections. After the regular lessons, the teachers were invited to participate in seminars led by the investigator. In these seminars, a special model of structured text talk was practiced before videotaping a second and a third time. The results demonstrate that during the structured text talks the teachers' question types had undergone a change. The number of purely factual questions had decreased. Instead there was an increase in the number of inferences and half‐open questions. The students read more actively during the structured text talks. They clearly made an effort to explore ideas in the text and made numerous inferences and reflections. 相似文献

Young children have better math abilities when their parents engage in more math‐related conversations with them. Yet, previous studies have found that math talk occurs only very infrequently in everyday interactions. In the present study, we sought to promote adult–child conversations about math in a naturalistic context using minimal instructions. We observed 179 adult–child dyads while they shopped in grocery stores with signs prompting them to engage in math‐related conversations (math condition), signs prompting them to talk about other topics (general language condition), or without any signs (baseline condition). In the math condition, more adults talked about math compared to the general language or the baseline condition, and this finding could not be explained by demographic characteristics of the dyad or the overall amount of conversations. This study demonstrates that cost‐effective signs placed in everyday contexts can promote math‐related conversations and potentially provide math learning opportunities for children. 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

This investigation examined 10th‐grade biology students' decisions to enroll in elective science courses, and explored certain attitudinal perceptions of students that may be related to such decisions. The student science perceptions were focused on student and classroom attitudes in the context of differing learning cycle classrooms (high paradigmatic/high inquiry, and low paradigmatic/low inquiry). The study also examined possible differences in enrollment decisions/intentions and attitudinal perceptions among males and females in these course contexts. The specific purposes were to: (a) explore possible differences in students' decisions, and in male and female students' decisions to enroll in elective science courses in high versus low paradigmatic learning cycle classrooms; (b) describe patterns and examine possible differences in male and female students' attitudinal perceptions of science in the two course contexts; (c) investigate possible differences in students' science perceptions according to their decisions to enroll in elective science courses, participation in high versus low paradigmatic learning cycle classrooms, and the interaction between these two variables; and (d) examine students' explanations of their decisions to enroll or not enroll in elective science courses. Questionnaire and observation data were collected from 119 students in the classrooms of six learning cycle biology teachers. Results indicated that in classrooms where teachers most closely adhered to the ideal learning cycle, students had more positive attitudes than those in classrooms where teachers deviated from the ideal model. Significantly more females in high paradigmatic learning cycle classrooms planned to continue taking science course work compared with females in low paradigmatic learning cycle classrooms. Male students in low paradigmatic learning cycle classrooms had more negative perceptions of science compared with males in high paradigmatic classrooms, and in some cases, with all female students. It appears that using the model as it was originally designed may lead to more positive attitudes and persistence in science among students. Implications include the need for science educators to help teachers gain more thorough understanding of the learning cycle and its theoretical underpinnings so they may better implement this procedure in classroom teaching. © 2001 John Wiley & Sons, Inc.

The purpose of this study was to investigate how concept cartoons, together with other diagnostic and scaffolding tools, could be used in formative assessment, to stimulate talk and argumentation among students in small groups, as part of peer‐assessment and self‐assessment; and to provide diagnostic feedback about students’ misconceptions to the teacher for teaching towards conceptual change. Two classes of Primary 5 and 6 students worked in small groups to discuss the opposing viewpoints posed by the cartoon characters, using scaffolding tools to guide their discussions and to evaluate, challenge, and document each others’ ideas. Students also used drawings to depict their ideas. The conversation from one group was audio‐taped. These tools provided a record of students’ thinking in a form that was accessible to the teacher for monitoring and feedback purposes. Findings showed dialogic talk and interactive argumentation among students where they made their reasoning visible. Students’ assertions and questions had formative potential as they encouraged exploratory and reflective discourse by drawing upon each others’ ideas. The teacher’s discursive practices, as well as her role in designing scaffolding structures for supporting ‘assessment conversations’ when using concept cartoons and in devising strategies that take into account students’ conceptual and epistemic thinking, are emphasised. 相似文献

Students' epistemological beliefs about scientific knowledge and practice are one important influence on their approach to learning. This article explores the effects that students' inquiry during a 4‐week technology‐supported unit on evolution and natural selection had on their beliefs about the nature of science. Before and after the study, 8 students were interviewed using the Nature of Science interview developed by Carey and colleagues. Overall, students held a view of science as a search for right answers about the world. Yet, the inconsistency of individuals' responses undermines the assumption that students have stable, coherent epistemological frameworks. Students' expressed ideas did not change over the course of the intervention, suggesting important differences between students' talk during inquiry and their abilities to talk epistemologically about science. Combined with previous work, our findings emphasize the crucial role of an explicit epistemic discourse in developing students' epistemological understanding. © 2003 Wiley Periodicals, Inc.
