This study analyzes six seventh grade Israeli mathematics textbooks, examining (1) the extent to which students are required to justify and explain their mathematical work, and (2) whether students are asked to justify a mathematical claim that is stated by the textbook or a mathematical claim that they themselves generated when solving a problem. Two different units of analysis were used to analyze two central topics in the seventh grade curriculum as follows: (1) equation solving in algebra and (2) triangle properties in geometry. The findings indicate that all six textbooks had considerably larger percentages of geometric tasks than algebraic tasks, which required students to justify or explain their mathematical work. Moreover, considerable differences were found among the six textbooks regarding the percentages of tasks that required students to justify and explain in both topics, but more so with the algebraic topic. Analysis of whether the textbook tasks required students to justify a mathematical claim that is stated by the textbook or a mathematical claim that the students themselves generated also revealed substantial differences among the textbooks. These findings are discussed, as well as the research methods used, in light of relevant literature.  相似文献

This study aims to analyse, based on common characteristics of the Nature of Science, how first year university Physics textbooks present the introduction of the concept and theories of magnetic field. It shows that despite the increasing number of studies into the Nature of Science in Science Education, Physics textbooks fail to adopt the results of this research. It is proposed that it would be plausible for textbooks to illustrate the characteristics of the Nature of Science by focusing on problems and changes in the development of the theory of magnetic field.  相似文献

In recent years, there has been upsurge of interest in the applications of interdisciplinary perspectives on science in science education. Within this framework, the implications of the so-called “economics of science” is virtually an uncharted territory. In this paper, we trace a set of arguments that provide a dialectic engagement with two conflicting agendas: (a) the broadening of science education to include the contextual positioning of science including economical dimensions of science, and (b) the guarding of the proliferation and reinforcement of those aspects of economics of science such as commodification of scientific knowledge that embraces inequity and restricted access to the products of the scientific enterprise. Our aim is broadly to engage, as science education researchers, in the debates in economics of science so as to investigate the reciprocal interactions that might exist with science education. In so doing, we draw out some recommendations whereby the goals of science education might provide as much input into the intellectual debates within philosophy of science on issues related to the commercialisation and commodification of scientific knowledge. We explore some implications of commodification of science in the context of modelling and argumentation in science education.  相似文献

This study has two purposes: the first is to explore experienced science teachers’ perspectives on inquiry teaching, and the second is to categorize these perspectives into patterns. Fifteen junior high school science teachers experienced at inquiry teaching were selected, and a semi-structured interview was conducted to collect the teachers’ perspectives on inquiry and inquiry teaching. The findings indicate that these experienced science teachers hold multiple perspectives on inquiry and inquiry teaching. The two patterns generated from these teachers’ perspectives of inquiry and inquiry teaching were systematic-based inquiry instruction and learning-based inquiry instructions. Suggestions for science teacher educators are discussed in this paper.  相似文献

One of the aspects science education should focus on is learning about science.Achieving a good understanding of this aspect requires, among others, the useof the history of science. There is some evidence that teachers rely heavily ontextbooks to select the historical content they include in their physical sciencelessons. On the other hand, Portuguese physical science syllabuses are not veryexplicit about the teaching of the science. Therefore, textbook writers may notfeel compelled to give enough importance to the history of science in their textbooksand consequently little history of science will pervade the science lessons. This paperaims to present a theoretically grounded checklist developed for analysing the historical content of science textbooks. Five physics textbooks that are different with regard to historical content were analysed. Inter-ratter agreement was used in order to validate the checklist. The results of the analysis show that the checklist is able to reveal differences among textbooks and that the historical content included in the textbooks is hardly able to give students an adequate image of science and scientists' work.  相似文献

生命科学教学的美育是一种教育思想、教学方法和教学模式,其核心内容是将生命科学的教学内容转化成审美的对象和内容,在生命科学的教学中始终渗透着美育教育,因此美育教育既是素质教育的需要,也是生命科学教学的需要。在生命科学的教学中要善于找到、挖掘和发现美育的各种构成要素,并将其融入教学之中,达到最佳的教学效果,满足日益增长的教学需求和需要。  相似文献

Scientists’ science differs remarkably from school science. In order to be taught to students, science is recontextualized from scientific research communities to science classrooms. This paper examines scientific discourse in scientific research communities, and discusses its transformation from an internally-persuasive and authoritative discourse to a purely authoritative discourse under recontextualization. It presents the challenges that recontextualization of science poses for achievement of science literacy goals, and discusses remedial steps that science education community can take to meet them.  相似文献

Molecular life science is one of the fastest-growing fields of scientific and technical innovation, and biotechnology has profound effects on many aspects of daily life—often with deep, ethical dimensions. At the same time, the content is inherently complex, highly abstract, and deeply rooted in diverse disciplines ranging from “pure sciences,” such as math, chemistry, and physics, through “applied sciences,” such as medicine and agriculture, to subjects that are traditionally within the remit of humanities, notably philosophy and ethics. Together, these features pose diverse, important, and exciting challenges for tomorrow''s teachers and educational establishments. With backgrounds in molecular life science research and secondary life science teaching, we (Tibell and Rundgren, respectively) bring different experiences, perspectives, concerns, and awareness of these issues. Taking the nature of the discipline as a starting point, we highlight important facets of molecular life science that are both characteristic of the domain and challenging for learning and education. Of these challenges, we focus most detail on content, reasoning difficulties, and communication issues. We also discuss implications for education research and teaching in the molecular life sciences.  相似文献

Recent research in science education has recognized the importance of history and philosophy of science. The objective of this study is to evaluate the presentation of the Thomson, Rutherford, and Bohr models of the atom in general physics textbooks based on criteria derived from history and philosophy of science. Forty-one general physics textbooks (all published in the United States) were evaluated on two criteria based on Thomson's work, three on Rutherford's work, and three on Bohr's work. Results obtained show that general physics textbooks do not systematically include a history and philosophy of science perspective. Most textbooks present an inductivist perspective in which experimental details are considered to be paramount. On the contrary, a historical reconstruction of the experimental details inevitably includes: the context in which an experiment is conducted, the theoretical framework that guides the scientist, and alternative interpretations of data that lead to conflicts and controversies. Examples are provided to show how historical reconstructions of atomic models can provide students an opportunity to appreciate how scientists work and science progresses. It is plausible to suggest that textbook presentations based on a history and philosophy of science perspective can perhaps arouse students' interest in the subject and hence lead to greater conceptual understanding.  相似文献
