The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011 相似文献

This paper sets out an argument and approach for moving beyond a primarily arts‐based conceptualization of cultural capital, as has been the tendency within Bourdieusian approaches to date. We advance the notion that, in contemporary society, scientific forms of cultural and social capital can command a high symbolic and exchange value. Our previous research [Archer et al. (2014) Journal of Research in Science Teaching 51, 1–30] proposed the concept of “science capital” (science‐related forms of cultural and social capital) as a theoretical lens for explaining differential patterns of aspiration and educational participation among young people. Here, we attempt to theoretically, methodologically, and empirically advance a discussion of how we might conceptualize science capital and how this might be translated into a survey tool for use with students. We report on findings from a survey conducted with 3658 secondary school students, aged 11–15 years, in England. Analysis found that science capital was unevenly spread across the student population, with 5% being classified as having “high” science capital and 27% “low” science capital. Analysis shows that levels of science capital (high, medium, or low) are clearly patterned by cultural capital, gender, ethnicity, and set (track) in science. Students with high, medium, or low levels of science capital also seem to have very different post‐16 plans (regarding studying or working in science) and different levels of self‐efficacy in science. They also vary dramatically in terms of whether they feel others see them as a “science person.” The paper concludes with a discussion of conceptual and methodological issues and implications for practice. © 2015 The Authors.

Working at scientists’ elbows is one suggestion that educators make to improve science education, because such “authentic experiences” provide students with various types of science knowledge. However, there is an ongoing debate in the literature about the assumption that authentic science activities can enhance students’ understandings of scientific practice. The purpose of the study is to further address the debate in terms of the ethnographic data collected during an internship programme for high school students right through to their public presentations at the end. Drawing on activity theory to analyse these presentations, we found that students presented scientific practice as accomplished by individual personnel without collaboration in the laboratory. However, our ethnographic data of their internship interaction show that students have had conversations about the complex collaborations within and outside the laboratory. This phenomenon leads us to claim that students experienced authentic science in their internships, but their subsequent representations of authentic science are incomplete. That is, participating in authentic science internships and reporting scientific practice are embedded activities that constitute different goals and conditions rather than unrefracted reflections of one another. The debate on the influence on students’ understanding of science practice is not simply related to situating students in authentic science contexts, but also related to students’ values and ideology of reporting their understanding of and about science. To help students see these “invisible” moments of science practice is therefore crucial. We make suggestions for how the invisible in and of authentic science may be made visible. 相似文献

This study further extends a conceptual framework that explores science teaching as a “practice” not reducible to the application of formal knowledge, but as informed by teachers' practical‐moral knowledge. A hermeneutic model was developed to examine practical‐moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions between them. The study also aimed to analyze teachers' actions in terms of their interpretations and commitments as they realize “internal goods” of their practice. Ethnographic case studies of three science teachers were conducted through classroom observation, in‐depth interviews and dialogues, and artifact analysis. A commitment of preparing students for national exams was common to the three teachers but was manifested differently in classroom practices. This commitment originated from interpretations about the duty of “good” teachers not letting students and schools down. Other emergent commitments were commitments: to conceptual understandings, to “challenge” learners, and to social modeling. We present each with associated interpretations and actions. The concepts of practical wisdom (phronesis) and gap closing are used to characterize teachers' practical knowledge and its development respectively. Implications for teacher education are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 929–951, 2010 相似文献

This article explores Complexity Theory and applications of nonlinear dynamics in physical education (PE). The authors of this article discuss Complexity Theory and its applications to students and student learning. Additionally, there will be discussion of how the networking learning process associated with socio-coordinated mimicry creates a “movement conversation” between learners rooted in the relational complexity of students within a PE lesson. Finally, the authors discuss research opportunities within PE, allowing for a close collaboration between pedagogical researchers and biomechanists to examine the emergent qualities within the “movement conversations” between students. Overall, this article seeks to illustrate the possibilities of utilizing Complexity Theory within PE pedagogy and research. 相似文献

When evaluating equity, researchers often look at the “achievement gap.” Privileging knowledge and skills as primary outcomes of science education misses other, more subtle, but critical, outcomes indexing inequitable science education. In this comparative ethnography, we examined what it meant to “be scientific” in two fourth‐grade classes taught by teachers similarly committed to reform‐based science (RBS) practices in the service of equity. In both classrooms, students developed similar levels of scientific understanding and expressed positive attitudes about learning science. However, in one classroom, a group of African American and Latina girls expressed outright disaffiliation with promoted meanings of “smart science person” (“They are the science people. We aren't like them”), despite the fact that most of them knew the science equally well or, in one case, better than, their classmates. To make sense of these findings, we examine the normative practice of “sharing scientific ideas” in each classroom, a comparison that provided a robust account of the differently accessible meanings of scientific knowledge, scientific investigation, and scientific person in each setting. The findings illustrate that research with equity aims demands attention to culture (everyday classroom practices that promote particular meanings of “science”) and normative identities (culturally produced meanings of “science person” and the accessibility of those meanings). The study: (1) encourages researchers to question taken‐for‐granted assumptions and complexities of RBS and (2) demonstrates to practitioners that enacting what might look like RBS and producing students who know and can do science are but pieces of what it takes to achieve equitable science education. © 2011 Wiley Periodicals, Inc., Inc.

This paper reports the results of a study of the relationship of robotics activity to the use of science literacy skills and the development of systems understanding in middle school students. Twenty‐six 11–12‐year‐olds (22 males and 4 females) attending an intensive robotics course offered at a summer camp for academically advanced students participated in the research. This study analyzes how students utilized thinking skills and science process skills characteristic of scientifically literate individuals to solve a robotics challenge. In addition, a pre/post test revealed that course participants increased their systems understanding, t (21) = 22.47, p < .05. It is argued that the affordances of the robotics environment coupled with a pedagogical approach emphasizing open‐ended, extended inquiry prompts the utilization of science literacy‐based thinking and science process skills and leads to increased systems understanding. © 2008 Wiley Periodicals, Inc.

禅门机缘语与中唐的尚奇之风 总被引：1，自引：0，他引：1
李壮鹰 《北京师范大学学报(社会科学版)》2001,(3):39-45
禅门机缘语的产生有其历史渊源和现实背景。从历史上说 ,魏晋清谈的“赌理”,是禅家机缘对话的滥觞。禅门的一些基本辩论方式以及所辩论的内容 ,在魏晋清谈之中早有端倪。从中唐以后的社会状况来看 ,由于战乱频仍 ,大量流民涌入禅门 ,迫使禅门授徒方针由原来的招揽改为拒斥 ,所以也就造成了机缘语的隐晦与诡怪。此外 ,中唐以后 ,由于社会和人们心态的变化 ,整个文化界出现一种尚奇和“解构”之风 ,机缘语的奇特 ,也是这种思潮的反映 ,它是与当时的文化语境密切相关的。 相似文献

Animated pedagogical agents (APAs) have the potential to provide one‐on‐one, just‐in‐time instruction, guidance or mentoring in classrooms where such individualized human interactions may be infeasible. Much current APA research focuses on a wide range of design variables tested with small samples or in laboratory settings, while overlooking important practical issues relating to large‐scale, school‐based implementations. The present study provides an early step in addressing this gap by investigating the patterns, affordances and challenges of sustained classroom use of APAs. During a 15‐class‐period science curriculum, middle school students in the treatment groups (nDr C‐1 = 191; nDr C‐2 = 181) had uninterrupted classroom access to one of the two APAs, while control group students (n = 149) completed the same curriculum without APA access. Usage patterns indicate that students accessed the APAs on a fluctuating, “as needed,” basis corresponding to the introductory, information‐gathering, and synthesis and reporting segments of the curriculum. Survey results revealed no statistically significant difference in student feelings toward the APAs between the two treatments. While treatment students reported that the APAs were unique, reliable, timely resources, interviews indicate little difference between their experiences with the curriculum and those of the control group. Results presented here provide guidance for researchers and practitioners. 相似文献

Maughn Rollins Gregory 《Educational theory》2014,64(6):627-648
Recent articles on teaching controversial topics in schools have employed Michael Hand's distinction between “directive teaching,” in which teachers attempt to persuade students of correct positions on topics that are not rationally controversial, and “nondirective teaching,” in which teachers avoid persuading students on topics that are rationally controversial. However, the four methods of directive teaching discussed in the literature — explicit directive teaching, “steering,” “soft‐directive teaching,” and “school ethos endorsement” — make rational persuasion problematic, if not self‐defeating. In this essay, Maughn Rollins Gregory argues that “procedurally directive teaching” offers an alternative to such approaches because it derives from the intention to guide inquiry rather than to persuade. He demonstrates that the conceptual frameworks of perfectionism and antiperfectionism, which have been proposed for directive teaching on same‐sex marriage, can instead be used to generate open questions for student inquiry, as can a third, civil rights framework. Given these considerations, Gregory maintains that pedagogical guidance on this topic should be procedurally directive rather than substantively directive. Further, the fact that legal, political, and ethics scholars disagree about which framework is more appropriate to the issue of same‐sex marriage indicates that such arguments cannot be dispositive of the pedagogical issue of how to frame classroom discussions about it. Rather, students should inquire into this meta‐level framing dispute for themselves. 相似文献

Research in science education confirms the importance of self-efficacy in students' persistence and success in the sciences. The current study examined the role of science self-efficacy in nonspecialist, arts and communication-oriented students encountering science in a general education context. Participants (N = 275) completed a beginning- and end-of-semester survey including a Science Self-Efficacy Scale, a “connection to science” measure—the Inclusion of Science in Self Scale—and a Science Anxiety Scale. Participants also responded to two open-ended “sources of science efficacy” questions, and provided background/demographic information and access to their academic records. Results showed a significant increase in science self-efficacy and connection to science—although no change in science anxiety—over the course of the semester. The observed shift in self-efficacy for minority and international students was of particular note. These students started the course with lower confidence but, by the end of the semester, reported comparable science self-efficacy, and achieved similar grades to their White/Non-Hispanic and US resident classmates. Contrary to expectations, science self-efficacy did not predict performance in the class. However, students' self-reported sources of efficacy indicated increased confidence in using science in daily life, and confirmed the value of mastery experiences and of personally meaningful, student-centered course design in scaffolding student confidence. Results are discussed in terms of the individual and instructional factors that support science self-efficacy and student success in this unique, general education science environment. 相似文献

Modeled after Horace Miner's classic article “The Body Ritual of the Nacirema,” an explanation of modern day Nacirema undergraduates as “academic deviants” is used as a pedagogical tool for negotiating criminological theory. Similar to the question, why do people commit crime, this paper asks why are some students “criminal”, i.e., poor students? 相似文献

In light of the perceived national need for more science and math teachers, this study was conceived to:
- 1. Identify “teaching oriented” students among freshmen at a mid-western engineering school, who have chosen NOT to become teachers;
- 2. Find out what reasons these “potential” science and math teachers have for deciding not to pursue teaching careers;
- 3. Determine what amelioration of these problems would be necessary for them to no longer be factors which would inhibit students from becoming teachers.

Large enrollment foundational courses are perceived as “high stakes” because of their potential to act as barriers for progression to the next course or admittance to a program. The nature of gateway courses makes them ideal settings to explore the relationship between anxiety, pedagogical interventions, and student performance. Here, two‐stage collaborative examinations were implemented to improve test‐taking skills and address widespread test anxiety in an introductory human anatomy course. Test anxiety data were collected (using the Motivated Strategies for Learning Questionnaire) before the first examination and last examination. Most students experienced decreased test anxiety over the course of the semester; however, some students may have experienced performance limiting conditions due to test anxiety at the end of the semester based on academic ability in the course (in “C” students when compared to “A” students: P < 0.00006 and “B” students: P < 0.05), overall academic ability (in academically weaker students: P < 0.025), and demographic factors (in women: P < 0.025). The strongest performances on examinations were primarily observed in already academically strong students (mean individual performance: P < 0.000, mean group performance: P < 0.000). Furthermore, changes in test anxiety were not significantly associated with the group portion of the examinations. Patterns of changes in test anxiety over the course of the semester underscore a complex interaction between test anxiety, student background, and student performance. Results suggest that pathways for test anxiety in “high stakes” courses may be separate from the mechanisms responsible for the benefits of collaborative testing.

Computing is anticipated to have an increasingly expansive impact on the sciences overall, becoming the third, crucial component of a “golden triangle” that includes mathematics and experimental and theoretical science. However, even more true with computing than with math and science, we are not preparing our students for this new reality. It is appropriate and compelling therefore to consider how computer science can be fundamentally integrated into science education. This study is a ten-year review (1998–2008) of the Journal of Science Education and Technology, with the following research questions in mind: What are the intersections at the K-16 level between science and computing? What do K-16 science educators already know about the newly emerged field, computational science? 相似文献

The role that family communication patterns (FCPs), sex, and Facebook® use play in young adults' decisions to “friend” their parents on Facebook was examined, as well as whether students who friend parents adjust their privacy settings. Results from an online survey of college students (N = 189) indicated that young adults who friend their parents are more likely to be female and report higher conversation FCPs than those who do not friend their parents. In addition, young adults who adjust privacy settings after friending parents (25.3%) update their profiles more often and report lower conversation and higher conformity FCPs than young adults who do not adjust privacy settings. 相似文献

In my technical writing class, I examine two “meanings” from the Challenger disaster to illustrate the social contingency of meaning even in science and technology. These instances are the “anomalous” charring of the O‐rings and the reconceptualized assumption of flightworthiness the night before the launch. The social contingency of these meanings shows that the “object” of technical communication is not the material object as a pre‐existent isolate but in its social interpretation, significance, and meaning. Ultimately, technical communication is about people communicating about and to the interests of other people. 相似文献
