This study investigated Emirates pre-service and in-service teachers' views about the nature of science. A questionnaire was developed and administered to 31 female pre-service science teachers, and 224 inservice chemistry teachers. The questionnaire covered five aspects of the nature of science identified by Palmquist and Finley (1997). These are: scientific theories and models; role of a scientist; scientific knowledge; scientific method; and scientific laws. The results indicated that Emirates teachers' views are neither clearly traditional nor clearly constructivist - they held mixed views about the nature of science. The study attributed the existence of the traditional views to historical reasons and the educational system. The presence of constructivist views was attributed to religious factors, where some of students' religious beliefs agree with some constructivist views. The study argued that the traditional view about the nature of science is in conflict with the teachers' religious beliefs. Teaching science in the Arab culture using the traditional view about science creates what Tobin (1996) called 'symbolic violence'. The study concluded that introducing science from the constructivist point of view and using what Jegede (1996) called 'collateral learning' would help to diminish such violence.  相似文献

The purpose of the study was to determine what percentage of Palestinian science teachers held beliefs about knowledge and learning that are congruent with the recent constructivist/conceptual change epistemological basis of science education, what factors influence these beliefs, and if the beliefs about knowledge and learning were related. Two questionnaires were developed to probe teachers' beliefs in these two areas, and a sample consisting of 91 teachers with varying educational background and teaching levels responded to these questionnaires. The study showed that only a small percentage of Palestinian teachers subscribed to the recent views of learning and scientific knowledge (25% and nine percent respectively). With regard to the views of learning, this was mainly due to very few teachers believing or realising that students hold alternative preconceptions and that science learning entails conceptual change. Very few teachers also believed that science itself develops through conceptual change. Indeed, more than 80% believed that science develops through accretion and about 40% preferred the inductive model of science to the hypothetico-deductive one which only 11% preferred. It was found that these views were not related to the teachers' years of schooling, years of experience, level at which they taught, or teacher specialisation. The two views of learning and knowledge were moderately related. The results and implications for future studies are discussed.  相似文献

This study tracked the influence of explicit reflective instructional methods on cultural values, ethical and intellectual development, and the relationship of these with preservice teachers' views of nature of science (NOS). The researchers used the Views of Nature of Science Form B (VNOS B) to describe NOS views, the Learning Context Questionnaire (LCQ) to classify preservice teachers' ethical and intellectual positions using Perry's scheme, and the Schwartz Values Inventory (SVI) to measure preservice teachers' cultural values. The interventions took place in two concurrent courses: a science methods course, and a foundations of early childhood course. The science methods course explicitly emphasized NOS throughout the semester, and the foundations of early childhood course reinforced these ideas through cultural activities that stressed empirical evidence. Analysis of data showed relationships between preservice teachers' Perry positions and responses on the VNOS B with those at higher positions exhibiting more informed NOS views. Relationships between preservice teachers' NOS views and their cultural values were identified, such as those at the dualism position holding achievement more highly for scientists than those at other Perry positions. The values preservice teachers held personally were different from those they held as important for scientists. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 748–770, 2008  相似文献

This study explored environmental worldviews of selected undergraduate students in Taiwan and located the associations of these worldviews with science. The “environment” is represented as nature or the natural world, as opposed to the social and spiritual world. The participants were undergraduate students (14 science and 15 nonscience majors) enrolled in a general science course at a southern Taiwanese university. A questionnaire and individual interviews were conducted in parallel to elicit in depth the students’ ideas/beliefs about nature, such as, to what construes nature, how it works, and how humans relate to nature. The responses were analyzed using a phenomenographic approach to emphasize the qualitative variation of the students’ views. The key findings based on their relations to science and science education were the following: (1) Most students seemed to immediately relate the topic of nature to science and thus sought to explain nature from a scientific perspective, yet their understanding of scientific concepts or metaphors, such as the balance of nature, was problematic; (2) a value-free perspective is evident among some students in viewing human-induced natural crises: What we should do is merely look at facts and let science tell us what we should and should not do. (3) The students generally expressed trust in science and technology and believed it to be the key to improving the condition of nature as well as human life.  相似文献

This study was conducted to explore the interplay between students’ scientific epistemological beliefs and their perceptions of constructivist learning environments. Through analysing 1,176 Taiwanese tenth-graders’ (16-year-olds) questionnaire responses, this study found that students tended to perceive that actual learning environments were less constructivist orientated than what they preferred. Students having epistemological beliefs more orientated to constructivist views of science (as opposed to empiricist views about science) tended to have a view that actual learning environments did not provide sufficient opportunities for social negotiations (p < 0.01) and prior knowledge integration (p < 0.01); and moreover, they show significantly stronger preferences to learn in the constructivist learning environments where they could (1) interact and negotiate meanings with others (p < 0.001), (2) integrate their prior knowledge and experiences with newly constructed knowledge (p < 0.001) and (3) meaningfully control their learning activities (p < 0.001). The main thrust of the findings drawn from this study indicates that teachers need to be very aware of students’ epistemological orientation towards scientific knowledge, and to complement these preferences when designing learning experiences, especially to provide constructivist-based lessons to enhance science learning for students who are epistemologically constructivist orientated.  相似文献

ABSTRACT

In recent years, there has been increasing interest within the engineering education research community to prepare engineering students to address wicked problems (WPs) such as climate change, resource scarcity and violent conflict. Previous research suggests that engineering students are able to address WPs if they are given adequate support, but there is a lack of research on what kinds of support are needed. This paper aims to reduce this gap by reporting on students’ performance in, and approaches to, addressing WPs when different scaffolding strategies were used in different parts of a rubric-based intervention. The intervention aimed to provide undergraduate engineering students with an understanding of the nature of WPs and with a structured way of addressing them. For each part of the intervention, we discuss affordances for learning provided by the different scaffolding strategies. The results suggest that strong cognitive scaffolding can support students’ understanding of the nature of WPs and students’ performance in written responses to WPs, but possibly also limits deep engagement with WPs and transfer of learning to other contexts.  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.

This study examined the views, and the retention of these views, of 19 preservice elementary teachers as they learned about nature of science (NOS). The preservice teachers participated in a cohort group as they took a science methods course during which they received explicit reflective instruction in nature of science. Through Views of Nature of Science version B (VNOS‐B) surveys and interviews it was found that most preservice teachers held inadequate ideas of nature of science prior to instruction, but improved their views after one semester of instruction in the science methods course. However, 5 months after instruction, the graduate preservice teachers were again interviewed and it was found that several of the students reverted back to their earlier views. The results are interpreted through Perry's scheme, and implications and recommendations for elementary science teacher education are made. © 2005 Wiley Periodicals, Inc.

This study explored views held by pre-service and in-service science teachers regarding the nature of science and technology particularly: (a) the characteristics of science and technology; (b) the aim of science and scientific research; (c) the characteristics of scientific knowledge and scientific theories; and (d) the relationship between science and technology. The views held by science teachers at pre-service and in-service levels were assessed using a questionnaire. The findings revealed that generally science teachers at both pre-service and in-service levels showed similar views in relation to the nature of science and technology. While the participants displayed mix views regarding science as content oriented or process oriented, technology was viewed as an application of science. Implications of these views for classroom teaching and learning are presented.  相似文献

An understanding of current views of the nature of science continues to be regarded as an important outcome of school science. Studies of the conceptions of the nature of science held by primary school teacher education students is therefore important. This article reports the conceptions held by 73 preservice primary teachers. There were elements in the conceptions of the nature of science articulated by this group which clearly were not in accord with modern views. For example, one in five, in many instances, chose responses which would be unacceptable to many modern philosophies of science. Further, many chose 'don't know' as a response to a variety of specific propositions about science, ranging from a low of 1.5% to 3.15% of respondents. The responses of school leavers and mature age students did not differ in any substantial way. In addition, the use of newspaper science reports is described as a novel means to probe conceptions of the nature of science.  相似文献

The study investigated the degree of ambiguity harbored by four different response modes used to monitor student beliefs about science-technology-society topics: Likert-type, written paragraph, semistrue tured interview, and empirically developed multiple choice. The study also explored the sources of those beliefs. Grade-12 students in a Canadian urban setting responded, in each of the four modes, to statements from Views on Science-Technology-Society. It was discovered that TV had far more influence on what students believed about science and its social, technological context than did numerous science courses. The challenge to science educators is to use the media effectively in combating naive views about science. Regarding ambiguity in student assessment, the Likert-type responses were the most inaccurate, offering only a guess at student beliefs. Such guesswork calls into question the use of Likert-type standardized tests that claim to assess student views about science. Student paragraph responses contained significant ambiguities in about 50% of the cases. The empirically developed multiple choices, however, reduced the ambiguity to the 20% level. Predictably, the semistructured interview was the least ambiguous of all four response modes, but it required the most time to administer. These findings encourage researchers to develop instruments grounded in the empirical data of student viewpoints, rather than relying solely on instruments structured by the philosophical stances of science educators.  相似文献

This study explores the relationship, if any, between an individual’s culturally based worldviews and conceptions of nature of science. In addition, the implications of this relationship (or lack of relationship) for science teaching and learning are discussed. Participants were 54 Taiwanese prospective science teachers. Their conceptions of nature of science and their worldviews specific to humans’ relationship with the natural world were assessed using two open‐ended questionnaires in conjunction with follow‐up interviews. Their understandings of nature of science were classified into informed and naïve categories based upon contemporary views of these constructs and those stressed in international reform documents. An anthropocentric–naturecentric continuum emerged and is used to explain the participants’ views about humans’ relationship with Nature. Participants who recognized the limitations of scientific knowledge, and accept the idea that science involves subjective and cultural components, were more likely to emphasize harmony with Nature. In contrast, participants who possessed narrow views about the scientific enterprise and described science as close to technology and as of materialistic benefit tended to provide an anthropocentric perspective regarding the human–Nature relationships. The findings illustrate the interplay between participants’ sociocultural beliefs and conceptions of nature of science. Concisely, people with different worldviews may have concurrently different views about nature of science. The study suggests the need for incorporating sociocultural perspectives and nature of science in the science curriculum.  相似文献

The international science education community recognises the role of pre‐service science teachers’ views about the interdependence of Science, Technology, and Society (STS) in achieving scientific literacy for all. To this end, pre‐service science teachers’ STS views signal the strengths and the weaknesses of science education reform movements. Turkey, a country that follows the international reform movement, aims at improving citizen’s understanding of the STS interdependence to enable them to fully participate in an industrialised, democratic society. This study explores the Turkish pre‐service science teachers’ views (n = 176) on STS issues and discusses the ongoing reform efforts’ strengths and weaknesses within the context of the study findings. Data were collected through an adopted “Views on Science–Technology–Society” instrument. Analysis revealed that many participants held realistic views on science, technology, and society interdependence, while their views on technology and the nature of science were differed. Some viewed technology as an application of science, and some viewed science as explanatory and an interpretation of nature. Most agreed that the scientific knowledge is tentative but they did not present a thorough understanding of the differences between hypotheses, laws, and theories.  相似文献

Written and oral communications and the processes of writing and reading are highly valued within the scientific community; scientists who communicate well are successful in gaining recognition and support from members of their own communities, the research funding agencies, and the wider society. Yet how do scientists achieve this proficiency? Are expert scientists equally expert writers in and of science? Do scientists' perceptions of the nature of science influence their writing strategies and processes, and their beliefs about the role of writing in knowledge construction? This study used a questionnaire and semistructured interviews to document these perceptions, strategies, processes, and beliefs in a nonrandom sample of Canadian university scientists and engineers. The results indicate that the scientists subscribed to a contemporary evaluativist view of science, used common writing strategies, held similar beliefs about scientific writing and nonscientific writing, and agreed that writing generates insights and clarifies ambiguity in science. The engineers held a different view of technology than the common views of science or technology as simply applied science. These findings were slightly different than those found for American scientists from a large land‐grant university. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 338–369, 2004  相似文献

This study aimed to assess grade 10 Turkish students' and science teachers' conceptions of nature of science (NOS) and whether these conceptions were related to selected variables. These variables included participants' gender, geographical region, and the socioeconomic status (SES) of their city and region; teacher disciplinary background, years of teaching experience, graduate degree, and type of teacher training program; and student household SES and parents' educational level. A stratified sampling approach was used to generate a representative national sample comprising 2,087 students and 378 science teachers. After establishing their validity in the Turkish context, participants were administered a questionnaire comprising 14 modified “Views on Science‐Technology‐Society” (VOSTS) items to assess their views of certain aspects of NOS. A total of 2,020 students (97%) and 362 teachers (96%) completed the questionnaire. Participant responses were categorized as “naïve,” “have merit,” or “informed,” and the frequency distributions for these responses were compared for various groupings of participants. The majority of participants held naïve views of a majority of the target NOS aspects. Teacher views were mostly similar to those of their students. Teacher and student views of some NOS aspects were related to some of the target variables. These included teacher graduate degree and geographical region, and student household SES, parent education, and SES of their city and geographical region. The relationship between student NOS views and enhanced economic and educational capitals of their households, as well as the SES status of their cities and geographical regions point to significant cultural (specifically Western) and intellectual underpinnings of understandings about NOS. © 2008 Wiley Periodicals, Inc.

In this study, we produced a documentary which portrays scientists at work and critically evaluated the use of this film as a teaching tool to help students develop an understanding of the nature of science. The documentary, “Life as a Scientist: People in Love with Caenorhabditis elegans, a Soil Nematode” encompasses the entire process of a scientific investigation by exploring the everyday life of a particular group of scientists. We explored the effectiveness of this documentary in teaching the nature of science by examining the epistemological views of college students toward science before and after viewing. In addition, we collected written responses from the students where they described which aspect of the nature of science they learned from the documentary. The scores of epistemological views toward science increased between the pretest and the posttest (p < 0.01) with the most significant increase being in their views of the role of social negotiation. In the written responses, approximately half of the students suggested that they had learned more about the role which cooperation and collaboration play in the development of scientific knowledge by watching the documentary. The documentary overall provides a valuable instructional context so that students are able to discuss and reflect on various aspects of nature of science within authentic scientific research.  相似文献

In his article Scientists at Play in a Field of the Lord, David Long (2010) rightly challenges our presumptions of what science is and brings forth some of the disjunctures between science and deeply held American religious beliefs. Reading his narrative of the conflicts that he experienced on the opening day of the Creation Museum, I cannot help but reconsider what the epistemology of science is and science learning ought to be. Rather than science being taught as a prescribed, deterministic system of beliefs and procedures as it is often done, I suggest instead that it would be more appropriate to teach science as a way of thinking and making sense of dialectical processes in nature. Not as set of ultimate “truths”, but as understandings of processes themselves in the process of simultaneously becoming and being transformed.  相似文献

Although recent studies have shown that the sociocultural characteristics which children in non-western society bring into the classroom from their environment create a wedge between what they are taught and what they learn, very little has been done to solve the problem. A learner who is not positively disposed to, or has a socio-cultural background that is indifferent to, learning science would find it hard to learn science effectively. This study investigated whether instruction through the use of the socio-cultural mode has any significant effect on students' attitude towards the learning of science. The sample consisted of 600 senior secondary year-one students (442 boys, 158 girls) from 15 secondary schools in Nigeria. The Socio-Cultural Environment Scale (SCES) and the Biology Achievement Test (BAT) were used to measure the change in attitude and achievement of subjects in a pretest-posttest situation after a six-week treatment. Evidence was found to support the hypothesis that science instruction which deliberately involves the discussion of socio-cultural views about science concepts engenders positive attitudes towards the study of science. The findings also indicate that anthropomorphic and mechanistic views can be presented in such a way as to promote positive attitudes towards the study of science in traditional cultures.  相似文献

This article describes views about the nature of science held by a small sample of science students in their final year at the university. In a longitudinal interview study, 11 students were asked questions about the nature of science during the time they were involved in project work. Statements about the nature of science were characterized and coded using a framework drawing on aspects of the epistemology and sociology of science. The framework in this study has three distinct areas: the relationship between data and knowledge claims, the nature of lines of scientific enquiry, and science as a social activity. The students in our sample tended to see knowledge claims as resting solely on empirical grounds, although some students mentioned social factors as also being important. Many of the students showed significant development in their understanding of how lines of scientific enquiry are influenced by theoretical developments within a discipline, over the 5–8 month period of their project work. Issues relating to scientists working as a community were underrepresented in the students' discussions about science. Individual students drew upon a range of views about the nature of science, depending on the scientific context being discussed. © 1999 John Wiley & Sons, Inc.
