A Reconstruction of Structure of the Atom and Its Implications for General Physics Textbooks: A History and Philosophy of Science Perspective 总被引：1，自引：0，他引：1
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

从当代科学哲学和科学社会学的视角出发,本分析了20世纪不同版本历史、语和物理教材中的科学化,认为其存在以下有待完善的地方：在科学观方面,应该进一步强调科学问题、科学假设作为科学活动重要的组成部分,深刻阐明科学是一种社会建制的思想;在科学价值观方面,应该充分阐明科学的负面价值与内在价值;在科学发展观方面,应当修正“科学成就史观”和“个人英雄史观”,确立“问题史观”,突出科学问题、科学论争与科学家共同体在推动科学发展中的重要作用;在科学家的形象表征方面,应该注意表现科学家从事科学工作更为重要的一些专业性品质。 相似文献

Research on understanding the full extent that an authentic science research experience engages students in how scientists think and act is sparse. ‘Learning-science-by-doing-science’ (LSDS) is an emerging self-guided process-learning model in postsecondary science education. It offers authentic science research opportunities that drive students to think and act like scientists. This study investigates the LSDS approach as a potential model for science learning at postsecondary level and aims to answer a main research inquiry – what are the students’ and teaching staff’s perceptions of students’ learning gains and the quality of their learning experiences in an authentic research environment within the LSDS model? To answer this question, data were collected from the students, alumni, instructors, teaching assistants and the program director via questionnaires, focus groups and interviews. Students’ and staff’s lived experiences and their perceptions on their authentic research experiences within the LSDS model were used to articulate the key attributes and stages of the LSDS model. The outcomes of this study can be used to help other science programs implement similar authentic research process learning approaches in their own contexts. 相似文献

Working with scientists has been suggested as an effective way for high-school students to learn authentic science. However, little research has involved students’ perceptions of science learning environments in a university internship. This study drew on the theoretical framework of community of practice with cogenerative dialogues to design an internship program that aims to build a constructivist internship for students. Students who learned science in the internship program developed stronger constructivist learning perceptions than those who learned science in school. Specifically, students perceived that they had more opportunities to think independently of the instructors and other students. Three effective principles for program design are: (a) high school students conduct open-inquiry projects with the support of scientists; (b) high school students and scientists conduct cogenerative dialogues regularly to address issues and share experiences; and (c) high school students present their project proposals and scientific findings at open house events. Implications of the results are discussed. 相似文献

The impact of scienceware and foundations on students' attitudes towards science and science classes
Steven J. Stratford Elizabeth A. Finkel 《Journal of Science Education and Technology》1996,5(1):59-67
In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems. 相似文献

Towards a Framework of Socio-Linguistic Analysis of Science Textbooks: The Greek Case 总被引：1，自引：0，他引：1

This study aims at presenting a grid for analysing the way the language employed in Greek school science textbooks tends to
project pedagogic messages. These messages are analysed for the different school science subjects (i.e., Physics, Chemistry,
Biology) and educational levels (i.e., primary and lower secondary level). The analysis is made using the dimensions of content
specialisation (classification) and social-pedagogic relationships (framing) promoted by the language of the school science
textbooks as well as the elaboration and abstraction of the corresponding linguistic code (formality), thus combining pedagogical
and socio-linguistic perspectives. Classification and formality are used to identify the ways science textbooks tend to position
students in relation to the interior of the corresponding specialised body of knowledge (i.e., in terms of content and code)
while framing is used to identify the ways science textbooks tend to position students as learning subjects within the school
science discourse. The results show that the kind of pedagogic messages projected by the textbooks depends mainly on the educational
level and not particularly on the specific discipline. As the educational level rises a gradual move towards more specialised
forms of scientific knowledge (mainly in terms of code) with a parallel increase in the students' autonomy in accessing the
textbook material is noticed. The implications concern the way both students and teachers approach science textbooks as well
as the roles they can undertake by internalising the textbooks' pedagogic messages and also the way science textbooks are
authored. 相似文献

This article presents an analysis of how scientists are portrayed in the Lebanese national science textbooks. The purpose of this study was twofold. First, to develop a comprehensive analytical framework that can serve as a tool to analyze the image of scientists portrayed in educational resources. Second, to analyze the image of scientists portrayed in the Lebanese national science textbooks that are used in Basic Education. An analytical framework, based on an extensive review of the relevant literature, was constructed that served as a tool for analyzing the textbooks. Based on evidence-based stereotypes, the framework focused on the individual and work-related characteristics of scientists. Fifteen science textbooks were analyzed using both quantitative and qualitative measures. Our analysis of the textbooks showed the presence of a number of stereotypical images. The scientists are predominantly white males of European descent. Non-Western scientists, including Lebanese and/or Arab scientists are mostly absent in the textbooks. In addition, the scientists are portrayed as rational individuals who work alone, who conduct experiments in their labs by following the scientific method, and by operating within Eurocentric paradigms. External factors do not influence their work. They are engaged in an enterprise which is objective, which aims for discovering the truth out there, and which involves dealing with direct evidence. Implications for science education are discussed. 相似文献

This study examined the nature of science (NOS) views of lower elementary grade level students, including their views of scientists. Participants were 23 third‐grade African American students from two Midwest urban settings. A multiple instrument approach using an open‐ended questionnaire, semi‐structured interviews, a modified version of the traditional Draw‐A‐Scientist Test (DAST), and a simple photo eliciting activity, was employed. The study sought to capture not only the students' views of science and scientists, but also their views of themselves as users and producers of science. The findings suggest that the young African American children in this study hold very distinct and often unique views of what science is and how it operates. Included are traditional stereotypical views of scientists consistent with previous research. Additionally, participants expressed excitement and self‐efficacy in describing their own relationship with science, in and outside of their formal classrooms. Implications for teaching and learning NOS as it relates to young children and children of color are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 49: 1–37, 2012 相似文献

Research in science education has recognized the importance of history and philosophy of science. Given this perspective, the study was designed to develop a framework for examining the way in which chemistry textbooks describe the kinetic theory and related issues. The framework was developed by a rational reconstruction of the kinetic molecular theory of gases based primarily on the interpretations of Maxwell and Boltzmann, by historians and philosophers of science. Another aspect of the framework was based on an analysis of freshman chemistry students' performance on gas problems that required the use of algorithms or conceptual understanding. Subsequently, 22 textbooks were evaluated using a framework consisting of six criteria. Results obtained showed that most textbooks lacked a history and philosophy of science framework and did not deal adequately with the following aspects: (1) Postulates of the kinetic theory were speculative and played the role of simplifying assumptions, considered to be the rule in science rather than being the exceptions; (2) Based on these simplifying assumptions, the theorists built a series of tentative models that progressively incorporated the behavior of real gases; (3) Similar to other research programs in the history of science, Maxwell's was based on inconsistent foundations; (4) Development of the kinetic theory had to compete with chemical thermodynamics, a rival research program; (5) Maxwell and Boltzmann facilitated our understanding of gas behavior beyond the observable hydrodynamical laws, by explaining the internal properties (e.g., molecular collisions). 相似文献

Visual representations are ubiquitous in modern‐day science textbooks and have in recent years become an object of criticism and scrutiny. This article examines the extent to which changes in representations in textbooks published in the USA over the past six decades have invited those critiques. Drawing from a correlational analysis of a corpus of 34 US middle school physical science textbooks, continuities are established with respect to the purposes that most textbook images serve and the numbers of schematic representations that are used. Changes are observed in the overall total number of representations in textbooks and in the proportion of representations that are photographic. Interpretive cases of individual representations over time are presented to further illustrate the continuities and changes that have taken place. Specifically, high‐fidelity images, such as photographs, are shown permeating or replacing schematic and explanatory images in the interest of promoting familiarization to students. This shifting emphasis toward familiarization is discussed as a specific cause for concern about quality and utility of representations in modern‐day US science textbooks. 相似文献

ABSTRACTFor some time now, images in science have been an object of study in the history of science. The multiple roles that images play in scientific practice have been recognised and discussed. However, little attention has been given to science related images in educational contexts. The case of geology is all the more relevant because it is considered that it has a specific visual language that is intrinsic to its own constitution as a science. This work aims to contribute to counter this situation through the analysis of geology-related images present in textbooks for Portuguese secondary education in the period between 1836 and 1974. Temporal limits correspond to the creation of secondary education in Portugal and to the end of the Estado Novo. For this period, five textbooks were chosen and their images analysed. The place of geological subjects in the context of science teaching in Portuguese secondary education was also traced. The interpretation of the results shows that images present in textbooks had other purposes besides introducing students to the typical visual language of geology. In fact, one of their main intentions was to “shape” the student’s mind into a “rational way of thinking”. 相似文献

Task orientation is currently a prominent concept under discussion in primary school didactics. It focuses on tasks along which pupils acquire competences on distinct levels of competence. The qualitative empirical study TAPSE (Textbook Analysis in Primary Science Education) pursues the question which conception of task orientation is present in current textbooks in primary science education. The study follows two foci: (a) The introduction of a new category system for the analysis of the task-orientation potential of tasks, based on the further development of existing category systems for analyzing tasks; and (b) the analysis of 994 task statements in science textbooks with respect to the didactic quality of their task orientation. The sample included nine primary science textbooks, four from Germany, and five from Luxembourg. Textbooks were selected from the most frequently sold series in the respective country. All tasks of the textbooks were analyzed deductively and inductively by four coders in three steps: (a) Identifying tasks with task-oriented potential; (b) itemizing different types of task-orientation potential; and (c) comparing the textbooks with respect to country- and period-specific manifestations of task orientation. Analysis indicated that (a) there are few tasks which meet the criteria of task orientation; (b) distinct types of task orientation can be generated, among which implicit forms dominate; and (c) differences occur in the characteristics of task orientation between older and newer textbooks as well as between German and Luxembourgish ones. Central points of discussion ensue from this: The need to develop models for social and cognitive activation for tasks, challenges for professional development for teachers, and support for pupils—in particular high achieving heterogenization. 相似文献

This research examines the effects of the Horsham Greenpower Goblin Challenge (HGGC), a hands-on science, engineering and technology (SET) project, on the attitudes of Year 5, primary-school children towards SET. The data collection centred on pre- and post-HGGC questionnaires using Likert scales and picture/word images of scientists and engineers. It was found that the HGGC did not significantly alter children's attitudes to SET and did not dispel previous negative images and attitudes. It was concluded that a greater understanding and acknowledgement of children's existing attitudes was required when designing initiatives aimed at dispelling negative and promoting positive images of SET. 相似文献

This study examines the differences between teachers' and students' perceptions of textbook usage in the science classroom.
Four categories of use were identified: teacher directed student activities; teaching/studying guidance; as a source of information
for the user and as preparation for assessment. The results of the study show that differences do occur between teachers and
students with respect to their perceptions of the extent to which textbooks are used in the classroom and the purposes for
which they are used, namely as a teaching/studying guide and as preparation for assessment. The findings of the study should
be important to all those who use, write and publish high school science textbooks.

An explicit and reflective approach to the use of history to promote understanding of the nature of science 总被引：1，自引：1，他引：0
Monk and Osborne (Sci Educ 81:405–424, 1997) provide a rigorous justification for why history and philosophy of science should be incorporated as an integral component
of instruction and a model for how history of science should be used to promote learning of and about science. In the following
essay we critique how history of science is used on this model, and in particular, their advocacy of a direct comparison of
students’ conceptions of scientific phenomena with those of past scientists. We propose instead an alternative approach that
promotes a more active engagement by inviting students to engage in the sort of reasoning that led past scientists to reach
insights about scientific phenomena. As an example we describe in detail two lesson plans taken from an eight-class unit developed
with reference to the history of research on sickle-cell anemia. These lessons demonstrate how an open-ended, problem-solving
approach can be used to help students deepen their understanding of science. Throughout the unit students are invited to explicitly and reflectively consider the implications of their reasoning about the disease for their understanding of nature of science issues. The essay
draws attention to how this alternative approach actually more closely aligns with the constructivist rationale Monk and Osborne
have articulated. It concludes with a brief summary of empirical research demonstrating the efficacy of this approach.

This paper aims at presenting the application of a grid for the analysis of the pedagogic functions of visual images included in school science textbooks and daily press articles about science and technology. The analysis is made using the dimensions of content specialisation (classification) and social-pedagogic relationships (framing) promoted by the images as well as the elaboration and abstraction of the corresponding visual code (formality), thus combining pedagogical and socio-semiotic perspectives. The grid is applied to the analysis of 2819 visual images collected from school science textbooks and another 1630 visual images additionally collected from the press. The results show that the science textbooks in comparison to the press material: a) use ten times more images, b) use more images so as to familiarise their readers with the specialised techno-scientific content and codes, and c) tend to create a sense of higher empowerment for their readers by using the visual mode. Furthermore, as the educational level of the school science textbooks (i.e., from primary to lower secondary level) rises, the content specialisation projected by the visual images and the elaboration and abstraction of the corresponding visual code also increases. The above results have implications for the terms and conditions for the effective exploitation of visual material as the educational level rises as well as for the effective incorporation of visual images from press material into science classes. 相似文献

An important objective in science education is for students to understand the nature of science. Therefore, it is important that science textbooks, which are key resources in elementary science curricula, convey an accurate conception of the nature of science. This study examined first- to fifth-grade elementary science textbooks with regard to their presentations of the nature of science. 相似文献
