In this second article on the theory of ‘ground rules for talk’ I extend a debate between myself and Professor Neil Mercer over the introduction of ‘ground rules’ into classrooms. I critique ground rules through the use of sociological theory and argue that advocates of the ground rules perspective need to recognise the ideological nature of their theoretical position. In making this article a clear extension of my previous argument I introduce the work of Bernstein and Fairclough to support my new arguments. I use Bernstein's theory of pedagogy as cultural relay and Fairclough's appropriateness model of language variation to critique ‘ground rules perspectives’. In doing so, I draw out the political nature of educational theory and curriculum within the context of a specific socio-economic society.  相似文献

Some people think that science is a set of facts that can be presented in plain and unadorned language. This fosters a belief that science has few stories. Actually, stories are very important in school science. In an examination of science textbooks, I have identified four different types of science stories which I call (a) heroic, (b) discovery, (c) declarative, and (d) politically correct. Each of these types of story promotes a particular set of philosophical assumptions about science. These assumptions are presented implicitly within the framework of the story as truths of science. This article specifically examines the philosophical assumptions that underpin heroic science stories and the implications of these stories in the discursive practices of the school science classroom. As teachers, we need to be critically aware of these assumptions, since they may be at odds with our beliefs about knowledge and our preferred teaching practices. © 1998 John Wiley & Sons, Inc.

This project explores conceptual continuity as a framework for understanding students’ native ways of understanding and describing. Conceptual continuity suggests that the relationship between the use of words in one genre and the scientific genre can exist at varying levels of association. This perspective can reveal the varied relationships between ideas explained in everyday or vernacular genres and their association to scientific explanations. We conducted a 2-year study involving 15 high school baseball players’ understanding of the physics involved in baseball. First, we conducted a quantitative assessment of their science understanding by administering a test prior to season one (2006) and season two (2007). Second, we examined the types of linguistic resources students used to explain their understanding. Third, we revisited our data by using conceptual continuity to identify similarities between students’ conceptual understanding in the informal contexts and their similarities to canonical scientific ideas. The results indicated students’ performance on the multiple-choice questions suggested no significant improvement. The qualitative analyses revealed that students were able to accurately explain different components of the idea by using a diversity of scientific and non-scientific genres. These results call attention to the need to reconstruct our vision of science learning to include a more language sensitive approach to teaching and learning.  相似文献

I respond to Pike and Dunne by exploring the utilization of citizen science in science education. Their results indicate that students fail to pursue science beyond the secondary level, in part, because of prior educational experiences with science education. Students lack motivation to pursue degrees and careers in science because they feel science is not relevant to their lives or they are simply not good at science. With this understanding, the science education community now needs to move beyond a discussion of the problem and move forward with continued discourse on possible solutions. Science educators need to focus on developing connections between students’ everyday lives and science so that they will have tangible reasons for continuing with the lifelong learning of science. In this response, I will show that citizen science as an educational context holds much promise, respectively. Participation in citizen science projects moves scientific content from the abstract to the tangible involving students in hands-on, active learning. In addition, if civic projects are centered within their own communities, then the science becomes relevant to their lives because it is focused on topics in their own backyards.  相似文献

This study investigated the degree that Science and Engineering Practices (SEPs) criteria from the Next Generation Science Standards (NGSS) were included in self-reported teaching practices of twelfth-grade science teachers in Jordan. This study sampled (n?=?315) science teachers recruited from eight different public school directorates. The sample was surveyed using an instrument adapted from Kawasaki (2015). Results found that Jordanian science teachers incorporate (SEPs) in their classroom teaching at only a moderate level. SEPs applied most frequently included ‘using the diagram, table or graphic through instructions to clarify the subject of a new science,’ and to ‘discuss with the students how to interpret the quantitative data from the experiment or investigation’. The practice with the lowest frequency was ‘teach a lesson on interpreting statistics or quantitative data,’ which was moderately applied. No statistically significant differences at (α?=?0.05) were found among these Jordanian science teachers’ self-estimations of (SEP) application into their own teaching according to the study’s demographic variables (specialisation, educational qualification, teaching experience). However, a statistically significant difference at (α?=?0.05) was found among Jordanian high school science teachers’ practice means based on gender, with female teachers using SEPs at a higher rate than male teachers.  相似文献

This study investigated how preservice teachers develop collective efficacy when preparing lesson plans for a science methods course, and how this collective efficacy changed over time. The data were collected from four preservice science teachers working in a group to fulfil the requirements of the course. Findings revealed that four factors, including collaborative work, sharing the same goal, attitudes towards group work and group cohesion, played an important role in the development of collective efficacy among preservice teachers. The study also showed that collective efficacy improved continuously over the semester.  相似文献

I begin by examining the natures of science and religion before looking at the ways in which they relate to one another. I then look at a number of case studies that centre on the relationships between science and religion, including attempts to find mechanisms for divine action in quantum theory and chaos theory, creationism, genetic engineering and the writings of Richard Dawkins. Finally, I consider some of the pedagogical issues that would need to be considered if the science/religion issue is to be addressed in the classroom. I conclude that there are increasing arguments in favour of science educators teaching about the science/religion issue. The principal reason for this is to help students better to learn science. However, such teaching makes greater demands on science educators than has generally been the case. Certain of these demands are identified and some specific suggestions are made as to how a science educator might deal with the science/religion issue.  相似文献

This article examines the literature on Native science in order to address the presumed binaries between formal and informal science learning and between Western and Native science. We situate this discussion within a larger discussion of culturally responsive schooling for Indigenous youth and the importance of Indigenous epistemologies and contextualized knowledges within Indigenous communities.

Resistance to more humanistic forms of science education is an endemic and persistent feature of university scientists as well as school science teachers. This article argues that science education researchers should pay more attention to its origins and to the subtleties of its stubborn influence. The paper explores some of the imperatives which dominate the continuing practices of teachers; the linkages between school and university science; and re-considers the relationships between learning science, learning to do science and learning about science. It draws on recent, prominent publications, as well as neglected and rather more contentious material, to underline the unhelpfully narrow view of science held by those who defend the traditional disciplinary influences of biology, chemistry and physics. Suggestions are made as to where those of a more radical and determined disposition should direct their attention in the interests of improved education, vital scientific progress as well as human survival. It is argued that university science must change in order to ensure that teachers better help their students to learn, do and appreciate science.  相似文献

Portrayals of science and scientists,and ‘science for citizenship’   总被引：1，自引：1，他引：0  
There are increasing calls in the science education community for ‘science for citizenship’ as an important goal for the school science curriculum of the 21st century. The potential influence of portrayals of science and scientists in popular culture on the achievement of this goal is explored in this paper through a review of the literature. We develop a framework of important questions citizens ask in considering personal and social decision making in relation to science and technology issues, and how portrayals of science and scientists might contribute to this decision making process.  相似文献

ABSTRACT

Numerous case studies suggest that integrating art and science education could engage students with creative projects and encourage students to express science in multitude of ways. However, little is known about art integration practices in everyday science teaching. With a qualitative e-survey, this study explores the art integration of science teachers (n?=?66). A pedagogical model for science teachers’ art integration emerged from a qualitative content analysis conducted on examples of art integration. In the model, art integration is characterised as integration through content and activities. Whilst the links in the content were facilitated either directly between concepts and ideas or indirectly through themes or artefacts, the integration through activity often connected an activity in one domain and a concept, idea or artefact in the other domain with the exception of some activities that could belong to both domains. Moreover, the examples of art integration in everyday classroom did not include expression of emotions often associated with art. In addition, quantitative part of the survey confirmed that integration is infrequent in all mapped areas. The findings of this study have implications for science teacher education that should offer opportunities for more consistent art integration.  相似文献

We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper.

ABSTRACT

Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students’ spoken or written argumentation. Consequently, teachers’ pedagogical practices regarding argumentation gain importance due to their impact on how they incorporate this practice into their classrooms. In this study, therefore, we investigated the instructional strategies adopted by science teachers for their argumentation-based science teaching. Participants were one elementary science teacher, two chemistry teachers, and four graduate students, who have a background in science education. The study took place during a graduate course, which was aimed at developing science teachers’ theory and pedagogy of argumentation. Data sources included the participants’ video-recorded classroom practices, audio-recorded reflections, post-interviews, and participants’ written materials. The findings revealed three typologies of instructional strategies towards argumentation. They are named as Basic Instructional Strategies for Argumentation, Meta-level Instructional ?St??rategies for ?Argumentation, and Meta-strategic Instructional ?St??rategies for ?Argumentation. In conclusion, the study provided a detailed coding framework for the exploration of science teachers’ instructional practices while they are implementing argumentation-based lessons.  相似文献

The Biology Fellows Program at the University of Washington aims to enhance diversity in science by helping students succeed in the rigorous introductory biology classes and motivating them to engage in undergraduate research. The composite Scholastic Achievement Test scores and high school grade point averages of the Biology Fellows are comparable to those of students who are not in the program; however, they earn, on average, higher grades in introductory biology classes than non-Biology Fellows. Underrepresented minorities and disadvantaged students in the program also earn higher grades in the introductory biology classes than do their non-Biology Fellows counterparts. Analysis of the performance of Biology Fellows shows that the program assists students who are not proficient in certain science process skills and that students who lack these skills are at risk for failing introductory biology. This evaluation provides insight for designing programs that aim to enhance the performance of beginning students of biology, particularly for underrepresented minorities, who want to obtain a life science degree.  相似文献

Science education literature explicitly and implicitly advocates basic tenets (criteria) for “the nature of science.” The purpose of this study was to investigate whether the science education tenets are also held by philosophers of science (those who study purported tenets of science), and furthermore, to reveal possible related philosophical positions underpinning differences in responses among the philosophers. The philosophers of science expressed significant disagreements with the tenets, and different philosophers of science varied on their views about the tenets. In addition, relationships were found among the philosophers' views of the nature of science, their views of philosophy of space, and with their philosophy of science in general. Therefore, the tenets that are advocated as basic criteria for science education's “the nature of science” must be reconsidered so that more accurate criteria may be developed for future nature of science research. © 1997 John Wiley & Sons, Inc.

Primary teachers, despite their critical role in fostering student interest in science, lack confidence and have negative attitudes towards teaching science, with this trend starting during initial teacher education. Though research on attitudes towards teaching science is well established, less is known about attitudes towards learning science. In order to advance our understanding in this area, this study mapped the entry and evolution of attitudinal profiles towards learning science of 108 primary education pre-service teachers undertaking a first-year science unit. Participants completed an online survey tapping on self-determination, grade motivation, self-efficacy, difficulty, interest, anxiety and enjoyment in science before the commencement of the unit (T1) and at the end of it (T2). Clustering methods were used to group participants into homogenous attitudinal profiles at both points in time. Subsequently, daughter profile analysis was used to examine qualitative changes in final profiles respective to entry. Four distinct attitudinal profiles were identified with 47% of the participants exhibiting the least favourable profiles at the start of the science unit. Migration (T1 to T2) was more prevalent from the least to the most favourable profiles, however, it did occur in the opposite direction. Findings revealed that, though pre-service teachers increased their confidence in their ability to learn science, their self-determination decreased in all but one of the eight resulting daughter profiles.  相似文献

The intent of the present study is to describe preservice elementary teachers’ understanding of science and how certain contextual variables contribute to this understanding.

Eighty students in three sections of an elementary science methods course participated in the study by completing a questionnaire. Six questions dealt with knowledge of science, theories and evolution. In addition, a 21‐item rating scale covering various aspects of science and science teaching was included.

The major theme arising out of the data is how beliefs affect preservice teachers’ understandings of science. The anthropocentricity in the subjects’ definitions and purposes of science, theories and evolution is the most explicit and pervasive of the beliefs influencing the conceptualizations of science. The often vague and misinformed definitions of theories add a further dimension of how science is perceived. When evolution is introduced, both the anthropocentric view of science and the misunderstood notion of theory come together to confound the subjects’ understanding. When asked about the teaching of evolution, the subjects’ confusion concerning the nature of science becomes strikingly evident.
