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.

This study investigated seventh grade learners' decision making about genetic engineering concepts and applications. A social network analyses supported by technology tracked changes in student understanding with a focus on social and conceptual influences. Results indicated that several social and conceptual mechanisms potentially affected how and why ideas were taken up in the learning system of the classroom. Mechanisms included copying or memetic processes such as “do as the smart students do” and friendship selection. Study outcomes are compared with the broader literature on memes and memetic processes to reveal general evolutionary ideas such as the development of prestige, identity versus problem‐solving strategies, extended phenotypes, and memeplexes. Educational implications for this research are also addressed. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 900–921, 2008  相似文献

The dialogue that occurs in science classrooms has been the subject of research for many decades. Most studies have focused on the actual discourse that occurs and the role of the teacher in guiding the discourse. This case study explored the neglected perspective of secondary science students and their beliefs about their role in class discussions. The study participants (N?=?45) were students in one of the three differentially tracked chemistry classes taught by the same teacher. Findings about the differences that exist among students from different academic tracks are reported. While it seems that epistemological beliefs focusing on content are common for the students in this study, the students' social framing in the different tracks is important to consider when teachers attempt to transition to more dialogic forms of discourse. Some key findings of this study are (a) students’ beliefs that science is a body of facts to be learned influenced the factors they deemed important for whole-class discussion, (b) students from the lower-level track who typically were associated with lower socioeconomic status were more likely to view their role as passive, and (c) students’ comfort level with the members of the class seemed to influence their decisions to participate in class discussions.  相似文献

How individuals come to perceive themselves in STEM is predicated on their understanding of what it means to be a member of the STEM community. This association is consequential when considering the perpetuation of white male ownership of STEM knowledge and power that forces learners identifying with groups systemically marginalized by racial and gender discrimination to adopt particular norms, values, and behaviors to gain recognition. In effect, these expectations help to maintain masculinized Discourses as STEM professionals are encultured to apply the same recognition criteria to which they were judged themselves. We examine how these Discourses are maintained even as learners who identify with groups that carry histories of systemic marginalization by racist, sexist, and elitist practices gain access to STEM communities. Specifically, we explore how university STEM students attending a Hispanic Serving Institution in the United States articulate gendered expectations of STEM membership through their characterization of themselves and others as (not) STEM people. Drawing from theories in Discourse, social identity, and feminist critiques of science, we describe how students implicitly recognize STEM identity in gendered ways. We discuss how our findings illuminate the mechanisms by which STEM recognition is afforded by pointing to its dependence on masculinized displays of STEM performances, competence, and interests, leading to a cycle of marginalization as learners are encultured to perpetuate existing STEM Discourses in their recognition of others. We discuss research implications for measurements of STEM identity that do not account for gendered Discourses and offer practical implications for the design of learning experiences that co-opt existing Discourses to inoculate gendered perceptions of a STEM person prototype. Lastly, we present a case for elevating the role of maternal caregivers and family immigration histories in STEM identity construction.  相似文献

科学哲学以及相关的自然科学在本质上是关于实在的知识。但这一结论本身只有在先验的视域中才能显示出清晰的含义,一般关于实在论的讨论也只有在先验视域中才能有逻辑的结果。然而在这一视域中的考察也表明,科学哲学的“超验性”问题又是与其实在本质直接相关的,先验哲学在研究其发生发展规律的同时又承认这一点。整个20世纪科学哲学进程都表明了一个科学的经验实在(论)的性质,同时这一进程也证实了先验哲学关于先天知识(先验逻辑)的普遍有效性的论述。  相似文献

Many personnel committees at colleges and universities in the USA use student evaluation of faculty instruction to make decisions regarding tenure, promotion, merit pay or faculty professional development. This study examines the construct validity and internal consistency reliability of the student evaluation of instruction (SEI) used at a large mid‐western university in the USA for both administrative and instructional purposes. The sample consisted of 73,500 completed SEIs for undergraduate students who self‐reported as freshman, sophomore, junior or senior. Confirmatory factor analysis via structural equation modelling was used to explore the construct validity of the SEI instrument. The internal consistency of students' ratings was reported to provide reliability evidence. The results of this study showed that the model fits the data for the sample. The significance of this study as well as areas for further research are discussed.  相似文献

This exploratory study examines the background characteristics, socio-cultural values and pedagogical beliefs that entering student teachers bring with them into the faculties of education and explores their possible implications for teacher education in the Turkish context. The study comprised 18,226 first-year student teachers from 51 faculties of education who participated in the study by responding to a three-section questionnaire developed by the research team. Their responses indicate that students entering education faculties typically come from families of lower-middle socio-economic status living in urban areas, tend to possess more traditional than secular-rational values and have not yet formed clear pedagogical beliefs.  相似文献

While supervising a student teacher in school, an incident occurred that highlighted a contradiction between my practice and my beliefs and prompted me to question why I do not always live the values I profess. The aim of this article is to investigate how self-study can help me to understand the complex and context-based situations of my practice. I draw on the work of other teacher educators to examine the potential of self-study to improve my practice. Through this exploration I have begun to transform the way that I comprehend teaching and learning in teacher education. I identify several tensions and challenges in implementing the methodology within my professional context. I believe that self-study can help us in our roles as teacher educators to develop more reflexive self-awareness and to problematize taken-for-granted assumptions relevant to our contexts of practice.  相似文献

Like many readers of this journal, I have long been an advocate of having science students introduced to philosophy of science. In particular, influenced by the Philosophy for Children movement founded by Matthew Lipman, I have advocated such an introduction as early as possible and have championed early secondary school as an appropriate place. Further, mainstream science curricula in a number of countries have, for some time now, supported such introductions (albeit of a more limited sort) under the banner of introducing students to the “Nature of Science”. In this paper, I explore a case against such introductions, partly in role as “Devil’s Advocate” and partly exploring genuine qualms that have come to disturb me. Generally speaking, my judgement is that no justification is available in terms of benefit to the individual or to society of sufficient weight to outweigh the loss of freedom of choice involved in such forced learning. One possible exception is a minimalist and intellectually passive “Nature of Science” introduction to some uncontroversial philosophical views about science. An earlier version of this paper was presented to the Seventh International Conference on the History and Philosophy of Science and Science Teaching, University of Winnipeg, Winnipeg and subsequently published in its proceedings (see my 2003). I am grateful to those who engaged in discussion of the paper upon its presentation. I am also grateful to the advice of this journal’s anonymous referees.  相似文献

科学哲学的文化转向及其对科学教育的影响   总被引:3,自引:0,他引:3  
科学哲学的文化转向使人们对科学的本质的认识由传统向现代转变。科学知识是暂时性、主观性、建构性的,它会不断地被修正和推翻。科学哲学的文化转向推动了科学教育改革。培养学生的科学素养是科学教育目标,科学教育应更加重视知识的产生和形成过程。科学学习过程要以探究为主要形式,同时注重对学生进行科学情感、态度与价值观的培养。科学哲学的文化转向将促进科学与人文的融合。  相似文献
