Pupils' expectation‐related errors oppose the development of an appropriate scientific attitude towards empirical evidence and the learning of accepted science content, representing a hitherto neglected area of research in science education. In spite of these apparent drawbacks, a pedagogy is described that encourages pupils to allow their biases to improperly influence data collection and interpretation during practical work, in order to provoke emotional responses and subsequent engagement with the science. The usefulness of this approach is borne out quantitatively by findings from a series of three randomized experiments (n = 158) which show superior gains using this pedagogy that are still significant 2 and 3 years after the initial treatment. In addition, pupils who experienced more intense emotions during treatment demonstrated the most gains after 6 weeks. This research is one element of a large‐scale study of expectation‐related observation in school science whose findings impact generally on the proper consideration of empirical evidence and the learning of science content. © 2009 Wiley Periodicals, Inc.

Social psychologists' attitude‐behavior theories can contribute to understanding science teachers' behaviors. Such understanding can, in turn, be used to improve professional development. This article describes leading attitude‐behavior theories and summarizes results from past tests of these theories. A study predicting science teachers' intention to incorporate environmental risk education based on these theories is also reported. Data for that study were collected through a mail questionnaire (n = 1336, radjusted = 80%) and analyzed using confirmatory factor and multiple regression analysis. All determinants of intention to act in the Theory of Reasoned Action and Theory of Planned Behavior and some determinants in the Theory of Trying predicted science teachers' environmental risk education intentions. Given the consistency of results across studies, the Theory of Planned Behavior augmented with past behavior is concluded to provide the best attitude‐behavior model for predicting science teachers' intention to act. Thus, science teachers' attitude toward the behavior, perceived behavioral control, and subjective norm need to be enhanced to modify their behavior. Based on the Theory of Trying, improving their attitude toward the process and toward success, and expectations of success may also result in changes. Future research should focus on identifying determinants that can further enhance the ability of these theories to predict and explain science teachers' behaviors. © 2002 Wiley Periodicals, Inc.

In this review, we explore the notion of teaching science to English language learners (ELLs) as a balancing act between simultaneously focusing on language and content development, on the one hand, and between structuring instruction and focusing on student learning processes, on the other hand. This exploration is conducted through the lens of a theoretical framework embedded in the Science Writing Heuristic approach, an approach exemplifying immersive orientation to argument-based inquiry. Three learning processes (learning through the language of science, learning about the language of science and living the language of science) and three classroom structures (collective zone of proximal development, symmetric power and trust relationships and teacher as decision-maker) are explored in relation to learning theories and empirical findings from second language acquisition and science, multicultural and teacher education bodies of work. Three themes – negotiation, embeddedness and non-threatening learning environments – to inform ELL science education emerged from the review. 相似文献

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration known as meta-analysis (Glass, 1976). A total of 27 different new science curricula involving one or more measures of student performance are included in this meta-analysis. Data were collected for 18 a priori selected student performance measures. The results of this meta-analysis reveal definite positive patterns of student performance in new science curricula. Across all new science curricula analyzed, students exposed to new science curricula performed better than students in traditional courses in general achievement, analytic skills, process skills, and related skills (reading, mathematics, social studies and communication), as well as developing a more positive attitude toward science. On a composite basis, the average student in new science curricula exceeded the performance of 63% of the students in traditional science courses. 相似文献

Post-Sputnik science curricula stress the importance of teaching science as scientists might practice it. This has been vividly illustrated in the laboratory-oriented curricula generated in the past ten years. Even more important has been the emphasis on applying learning theories to their construction. The American Association for the Advancement of Science has implemented the ideas of Robert Gagné in order to develop Science—A Process Approach. Jean Piaget's theory of intellectual development has been integrated into the Science Curriculum Improvement Study. It has been the investigator's observation that many teachers who use the newer science curricula fail to utilize to the fullest the methods implicit in a development theory; consequently, the objectives which include the products as well as the processes of science may not be achieved. This paper will report on an investigation of two types of postlaboratory discussion strategies and their effects on sixth grade children's learning of some science principles. The effects these discussion strategies had on the learning of four science processes are reported elsewhere. 相似文献

This article seeks to sharpen current conceptualizations of interests and engaged participation, and to derive lessons for the design of interest-driven science learning environments (formal and informal). The empirical basis of the research is a set of ethnographic records of two communities of amateur astronomers, as well as the details of astronomers' instantiations of the hobby. Hobbies are paradigmatic examples of interest-driven practices and thus they offer an excellent window into truly interest-related phenomena and processes. The analysis and data collection followed a grounded theoretical process, which I describe in two parts. First, I comb through the data iteratively and present a theory of persistent engagement in a hobby practice. Based on this theoretical sketch, I then explain how individuals' persistent, interest-based pursuit of amateur astronomy is made possible by 4 structural and process features of the practice, which together afford individuals the ability to continuously tailor the hobby: (a) an extensive and varied material infrastructure; (b) participating simultaneously across multiple communities/sites of astronomy practice; (c) activity structural resources that function as templates for short- and long-term activities; and (d) processes of collaboration and idea sharing. Lessons for the design of science learning environments that are truly interest-driven follow. 相似文献

Uncovering the Potential: The Role of Technologies on Science Learning of Middle School Students 总被引：1，自引：0，他引：1

There is, no doubt, untapped potential in using technological tools to enhance the understanding of science concepts. This
study examines the potential by observing 7th and 8th grade middle school students’ (n = 23) use of portable data collection devices in a nine-week elective class, Exploring Technologies. Students’ use of the data collection devices and subsequent interactions were traced through audiocassette and videocassette
recordings, field notes, and student artifacts. The culminating activity for the course was a scientific investigation that
required students to use the technologies to answer student-selected research questions. To illustrate the use of technology
as a mediatory tool, an inquiry investigation of three student groups is described. In examining the three groups of middle
school students the researchers encountered specific evidence of technology maximizing students’ science learning. The students
were able to use the portable data collection devices in their investigations as they discussed scientific ideas related to
temperature and heat. The study’s findings indicated that the three student groups were able to use the tools to conduct scientific
inquiry and engage in scientific discourse. Further research on instructional approaches that allow students to develop expertise
by using technology as tools to construct knowledge about complex phenomena is encouraged. 相似文献

The article investigates the Theory of Knowledge course of the International Baccalaureate Organization. After a short overview of the aims and objectives of the course, the assessment criteria and a popular textbook are investigated.
Shortcomings concerning the treatment of the natural sciences are highlighted and the problem is generalised to courses or
curricula that aim to reconcile agendas focusing on critical thinking and philosophical analysis on the one hand and traditional
science subject-agendas on the other. The article argues that these problems also surface in the actual teaching practice
and their implications for the curricula need to be taken more seriously. Three possible alternatives to overcome these problems
are outlined. The first is based on novel work in history and philosophy of science, the second on general theories of argumentation,
and the third on systematic exploration of student interests and stakes. 相似文献

The role of aesthetic curiosity in the manipulation of materials is often ignored or considered irrelevant in most science curricula. Contemporary practice in curriculum design emphasizes an approach that views science and art as separate types of explorations. Some historians of technology and science suggest that basic discoveries arise out of an aesthetic curiosity fostered by play with materials or ideas. Experience with certain familiar materials of aesthetic interest suggest that children will sustain play for long periods and easily mix metaphors of art and science in developing an understanding of the phenomena that are a part of the experience. Several examples are given of how this might be accomplished. 相似文献

How students come to know phenomena in terms of abstract concepts and theories through hands-on activities remains one of
the open problems in science education. In this study, we develop a theory of learning science through design activities by
employing a dialectical view of human activity that explicitly combines the mental and material in the same, irreducible unit
of analysis. Dialectical contradictions embodied by this unit, here conceptualized as resistance experienced from a first-person
perspective, constitute the inner forces that drive designing. Drawing on a large database of artifact designing constituted
during a four-month unit on simple machines, we examine how resistance, in its dialectical relation to contradiction contributes
to the unfolding design process and to the learning of scientific concepts and manual process skills during design. First,
an inner contradiction emerges in the designers' lifeworlds as an unintended outcome or a breakdown and thereby changes the
perceived world of a designer collective. Second, the dialectic of contradiction and resistance realized in this manner constitutes
a moment unfolding culture of science in its concrete form embodied in individual designers and therefore contributes to the
production and reproduction of culture. We conclude with a reflection on the implications our study makes to a non-dualist
view of knowing and learning.

This study examines young children’s ideas about natural science phenomena and explores possibilities in starting investigations
in kindergarten from their ideas. Given the possibilities inherent in how young children make sense of their experiences,
we believe it is critical to take children’s perspectives into consideration when designing any activities, and ideally, to
design activities from their perspectives and understandings. Specifically, this research focuses on 5- and 6-year old children’s explanations of
rainbows, and there are three main findings. First, our analysis demonstrates that opportunities to discuss their ideas revealed
children’s different perceptions of the phenomena of rainbows. Secondly, this research emphasizes that peer-to-peer interaction
in the co-construction of science concepts provided support to the children to learn from, and with, each other. Third, children’s initial explanations provided the teacher-researcher (second author) with a starting point
to scaffold her teaching from. Although rainbows are quite an abstract topic to try to reproduce in the classroom, the children
demonstrated their often sophisticated understandings of natural science phenomena, as well as their creative ideas as related
to rainbows. In order to foster an appreciation of themes in natural science, it is crucial to build from what children already
know and can do, and to use these emergent theories and considerations in designing curriculum. Thus, we draw implications
for the importance of teaching science at the early childhood level and for using children’s ideas as starting points in planning
instruction. 相似文献

This research compared how the scientific literacy-related goals of the current Chinese and Finnish national science curricula at primary school level are actualised using a revised Programme for International Student Assessment (PISA) scientific literacy framework in the content analysis of the curricula. The content of the curricula focuses principally on knowledge, followed by competencies and attitudes, respectively. The learning context was seen to be thoroughly integrated with the content in both countries. However, the curricula are written in different ways. Generally, the literacy objectives for both curricula are based on scientific knowledge (Vision I) and the application of knowledge-based skills in situations (Vision II). However, they are characterised by implicit views that derive from the pursuit of the value-driven transformation of individuals and society achieved through science education (Vision III). The Chinese curriculum appears to favour the Anglo-American curriculum tradition, whereas the Finnish curriculum appears to be more attached to the Bildung-Didaktik tradition in terms of core tasks and the specification of objectives. The recommendation is that Vision III should be included in the science curricula, and should explicitly relate to social and scientific topics with a view to furthering a scientifically literate public. 相似文献

In recent years, a number of curriculum reform projects have championed the notion of having students do science in ways that move beyond hands‐on work with authentic materials and methods, or developing a conceptual grasp of current theories. These reformers have argued that students should come to an understanding of science through doing the discipline and taking a high degree of agency over investigations from start to finish. This stance has occasionally been mocked by its critics as an attempt to create “little scientists”—a mission, it is implied, that is either romantic or without purpose. Here, we make the strong case for a practice‐based scientific literacy, arguing through three related empirical studies that taking the notion of “little scientists” seriously might be more productive in achieving current standards for scientific literacy than continuing to refine ideas and techniques based on the coverage of conceptual content. Study 1 is a classroom case study that illustrates how project‐based instruction can be carried out when teachers develop guidance and support strategies to bootstrap students' participation in forms of inquiry they are still in the process of mastering. Study 2 shows how sustained on‐line work with volunteer scientists appears to influence students' success in formulating credible scientific arguments in written project reports following an authentic genre. Study 3, using data from three suburban high school classes, suggests that involving students in the formulation of research questions and data analysis strategies results in better spontaneous use of empirical data collection and analysis strategies on a transfer task. The study also suggests that failing to involve students in the formulation of research can result in a loss of agency. The implications of these findings for future research and practice are discussed. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 234–266, 2004 相似文献

This article argues that reading, writing and argument are central to any conception of science as it is currently constituted. Moreover, it is through the texts of science, popular accounts or journalistic reported versions that the majority of the public interact with and consider the implications of the findings that science presents. However, the study of the language of science, science's epistemic base and the cultural norms and values that underpin its practice are currently considered only marginal to the teaching of science. Rather, the specialised laboratories provided for science teachers and the narrow conception of science embodied in the curriculum gives pre-eminence to science as an empirical activity in the naive belief that this is central to understanding the nature of science. The consequent failure to recognise the centrality of language, literacy and argument to science education leaves the majority ill equipped to become critical consumers of science. Change requires a concerted attempt to reconceptualise the priorities for science education through a mix of new curricula, new strategies and last, but not least, new modes of assessment. 相似文献

Concern is increasingly being expressed about the teaching of higher order thinking skills in schools and the levels of understanding
of scientific concepts by students. Metaphors for the improvement of science education have included science as exploration
and science as process skills for experimentation. As a result of a series of studies on how children relate evidence to their
theories or beliefs, Kuhn (1993a) has suggested that changing the metaphor to science as argument may be a fruitful way to
increase the development of higher order thinking skills and understanding in science instruction. This report is of a case
study into the coordination of evidence and theories by a grade 7 primary school student. This student was not able to coordinate
these elements in a way that would enable her to rationally consider evidence in relation to her theories. It appeared that
the thinking skills associated with science as argument were similar for her in different domains of knowledge and context.

Background: Research has primarily concentrated on adults’ implicit theories about high quality science education for all students. Little work has considered the students’ perspective. This study investigated high school students’ implicit theories about what helped them learn science. Purpose: This study addressed (1) What characterizes high school students’ implicit theories of what facilitates their learning of science?; (2) With respect to students’ self-classifications as African American or European American and female or male, do differences exist in the students’ implicit theories? Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively. Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p < .05 to ascertain ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged. Conclusions: African American and European American students’ implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students’ implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think and perceive to be important, addressing students’ implicit theories may be one way to enhance science education reform. 相似文献

This study investigated the use of a hands-on laboratory program as a means of improving student attitude toward science and increasing student achievement levels in science knowledge. Using a posttest-only control group design, curriculum referenced objective examinations were used to measure student achievement in science knowledge, and a posttest Q-sort survey was used to measure student attitude toward science. A one-way analysis of variance compared the groups' differences in achievement and attitude toward science. Analysis of covariance was used to determine the effect of the laboratory treatment on the dependent achievement variable with attitude toward science as the covariable. The findings showed that students who had regular laboratory instruction (a) scored significantly higher (p < .01) on the objective examination of achievement in science knowledge than those who had no laboratory experiences; (b) exhibited a moderate, positive correlation (r = .406) between their attitude toward science and their achievement; and (c) scored significantly higher (p < .01) on achievement in science knowledge after these scores were adjusted on the attitude toward science covariable. There were no significant differences in achievement or attitude toward science for the limited English proficiency groups. It was concluded that laboratory instruction influenced, in a positive direction, the students' attitude toward science, and influenced their achievement in science knowledge. It was recommended that science instruction include a regular laboratory experience as a demonstrated viable and effective instructional method for science teachers. This model of science instruction has been shown to be effective with students of diverse backgrounds who live within large urban centers. J Res Sci Teach 34: 343–357, 1997. 相似文献

This study examined the relationships that exist between high school science teachers' understanding of the Piagetian developmental model of intelligence, its inherent teaching procedure—the learning cycle—and classroom teaching practices. The teachers observed in this study had expressed dissatisfaction with the teaching methods they used, and, subsequently, attended a National Science Foundation sponsored in-service program designed to examine laboratory-centered science curricula and the educational and scientific theories upon which the curricula were based. The teachers who exhibited a sound understanding of the Piagetian model of intelligence and the learning cycle were more likely to effectively implement learning cycle curricula. They were able to successfully integrate their students' laboratory experiences with class discussions to construct science concepts. The teachers who exhibited misunderstandings of the Piagetian developmental model of intelligence and the learning cycle also engaged their students in laboratory activities, but these activities were weakly related to learning cycles. For example, the data gathered by their students were typically not used in class discussions to construct science concepts. Therefore, these teachers apparently did not discern the necessity of using the data and experiences from laboratory activities as the impetus for science concept attainment. Additional results comparing degrees of understanding, teaching behaviors and questioning strategies are discussed. 相似文献

This ethnographic study explored aspects of how the natural sciences were represented in a Reggio Emilia‐inspired laboratory preschool. The natural sciences as a discipline—a latecomer to preschool curricula—and the internationally known approach, Reggio Emilia, interested educators and researchers, but there was little research about science in a Reggio Emilia classroom. The current research aimed to gain insight into natural science experiences in a Reggio Emilia‐inspired classroom. To gain in‐depth information, this inquiry‐based study adapted a research design with ethnographic data collection techniques (i.e., interview, observation, document/artifact collection, and field‐notes), namely Spradley's Developmental Research Sequence Method, which was a well‐known, pioneer ethnographic method. The data were analyzed from an interpretive perspective using multiple lenses. These lenses included Spradley's DRS for the classroom culture, Corsaro's peer culture theory, the Reggio Emilia approach, and Ohio's Early Learning Content Standards. The study involved 18 preschoolers, 10 teachers, and a program director. The results indicated that the Reggio Emilia‐inspired preschool offered a science‐rich context that triggered and supported preschoolers' inquiries, and effectively engaged preschoolers' hands, heads, and hearts with science. The natural sciences learning in this Reggio Emilia‐inspired preschool classroom met and exceeded some of Ohio's prekindergarten standards. The results suggested that the Reggio pedagogy, grounded in inquiry, is compatible with science education goals. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 1186–1208, 2010 相似文献
