When students collaboratively design and build artifacts that require relevant understanding and application of science, many aspects of scientific literacy are developed. Design-based inquiry (DBI) is one such pedagogy that can serve these desired goals of science education well. Focusing on a Projectile Science curriculum previously found to be implemented with satisfactory fidelity, we investigate the many hidden challenges when using DBI with Grade 8 students from one school in Singapore. A case study method was used to analyze video recordings of DBI lessons conducted over 10 weeks, project presentations, and interviews to ascertain the opportunities for developing scientific literacy among participants. One critical factor that hindered learning was task selection by teachers, which emphasized generic scientific process skills over more important cognitive and epistemic learning goals. Teachers and students were also jointly engaged in forms of inquiry that underscored artifact completion over deeper conceptual and epistemic understanding of science. Our research surfaced two other confounding factors that undermined the curriculum; unanticipated teacher effects and the underestimation of the complexity of DBI and of inquiry science in general. Thus, even though motivated or experienced teachers can implement an inquiry science curriculum with good fidelity and enjoy school-wide support, these by themselves will not guarantee deep learning of scientific literacy in DBI. Recommendations are made for navigating the hands- and minds-on aspects of learning science that is an asset as well as inherent danger during DBI teaching.  相似文献

Previous research has shown that indigenous students in Australia do not enjoy equal educational outcomes with other Australians. This secondary analysis of PISA 2006 confirmed that this continues to be the case in science literacy for secondary students. However, the analysis also revealed that indigenous Australian students held interest in science equal to that of their non‐indigenous peers, and that observed variations in science literacy performance were most strongly explained by variations in reading literacy. These findings hold important implications for teachers, teacher educators, policy‐makers, and researchers. Firstly, acknowledging and publicly valuing indigenous Australian science knowledge through rethinking school science curriculum seems an important approach to engaging indigenous students and improving their literacy in science. Secondly, appropriate professional learning for practising teachers and the incorporation of indigenous knowing in science methods training in teacher preparation seems warranted. Additionally, we offer a number of questions for further reflection and research that would benefit our understanding of ways forward in closing the science literacy gap for indigenous students. Whilst this research remains firmly situated within the Australian educational context, we at the same time believe that the findings and implications offered here hold value for science education practitioners and researchers in other countries with similar populations striving to achieve science literacy for all.  相似文献

Teacher education is in the grip of change. Due to the new Australian Curriculum, no longer is it possible to plan and implement lessons without considering the inclusion of Information and Communication Technologies. Simply knowing about the latest technology gadgets is not enough. Information literacy is essential in today’s information-rich learning and working environment. Students and teachers must be able to engage with diverse learning technologies efficiently and effectively in the search for the “right information” at the “right time” for the “right purpose”. Key information literacy and inquiry skills have been recognised as vital learning goals by the Australian Curriculum Assessment and Reporting Authority and the International Society for Technology in Education and are thus critical in science teacher education. This paper examines the overlap of technology, pedagogy and science content in the Technological Pedagogical and Content Knowledge (TPACK) framework and its affordances for science educators, at the intersection between technology knowledge, science pedagogy (information literacy and inquiry) and science content knowledge. Following an introduction of the TPACK framework for science education, the paper reports the research findings, which illustrate that 90% of pre-service teachers thought the experimental unit improved their understanding of the inquiry process, 88% reported more confidence in their understanding of science concepts and 94% of students reported an increase in their knowledge and confidence of Web 2.0 tools in supporting scientific inquiry in science. The implications of this study are that the online inquiry improved students’ knowledge and confidence in the skills and processes associated with inquiry and in science concepts.  相似文献

The ongoing reform in science education in many countries, including Israel, has attainment of scientific literacy for all as one of its main goals. In this context, it is important to provide teachers with the opportunity to construct meaning for the term science literacy and by doing so to obtain a clear understanding of the new teaching goals. Here we report on a study in which teachers, as part of their professional development, were involved in defining the term ‘chemical literacy’; they discussed the need for it, and suggested educational experiences that are necessary in order to attain it. The programme was conducted as part of a reform in the content, as well as in the pedagogy, of chemistry education in Israel. The collected data provide some insights regarding the process by which the teachers’ perception of ‘chemical literacy’ developed and the way actual school practice influences teachers’ perception of ‘chemical literacy’.  相似文献

In line with a current global trend, junior secondary science education in Bangladesh aims to provide science education for all students to enable them to use their science learning in everyday life. This aim is consistent with the call for scientific literacy, which argues for engaging students with science in everyday life. This paper illustrates Bangladeshi science teachers’ perspectives of scientific literacy along with their views on teaching practices. Participating teachers held a range of perspectives of scientific literacy, including some naive perspectives. The paper also reports that whilst teachers’ verbalised practices in relation to their emphasis on engaging students with science in everyday life follows the emphases as required in teaching for promoting scientific literacy, their assessment practices may not be useful to promote it. The discussion explores the meaning of these findings and provides implications for school science educational practice in Bangladesh.  相似文献

A research study, mainly based on the notion of ‘scientific literacy’ from the Programme for International Student Assessment (PISA) 2003 assessment framework, was carried out obtaining data from the administration of an open written questionnaire with items covering three central scientific processes—describing, explaining and predicting scientific phenomena; understanding scientific investigation; and interpreting scientific evidence and conclusions—to 30 experienced in‐service secondary school science teachers. The purpose was to analyse their views regarding the competences on the mentioned scientific processes assessed by Science PISA tests: which of the competences assessed were the most frequently identified by teachers, which of the competences they considered presenting difficulties for their students, and, finally, which activities they used in their classes to promote similar competences. Our results indicated that teachers had different perceptions of one or other scientific processes considered relevant for scientific literacy in the PISA framework. Their awareness of the expected students’ difficulties did not necessarily match the competences intended to be assessed by either PISA or what they thought to be assessed. Moreover, their views differed depending not only on the type of scientific process but also on the underlying subject. Concern about the students’ need of reading fluently with understanding and of paying special attention during the test time was also observed.  相似文献

The Southwest Regional Laboratory, through major funding from the National Science Foundation (ESI-9450235), has developed a series of eight instructional modules for use in common secondary school physical science that address three central goals of U.S. science literacy education: (1) to motivate students who have previously shown little interest in science; (2) to accomplish deep change in students' internalized conceptions of the structure and workings of the physical world; and (3) to build greater understanding, in both teachers and students, of the process and culture of scientific activity.Beginning with a discussion of the conceptual scaffolding that undergirds the project's pedagogical approach, the paper presents an overview of MindWorks' goals, the materials that have been developed to achieve these goals, and the progress of the pilot implementation and project evaluation.  相似文献

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.

Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.

Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.

Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.

Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.

Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion.  相似文献

Although the term “scientific literacy” has been increasingly used in recent years to characterise the aim of school science education, there is still considerable uncertainty about its meaning and implications for the curriculum. A major national project in England, Twenty First Century Science, is evaluating the feasibility of a more flexible science curriculum structure for 15‐year‐old and 16‐year‐old students, centring around a core course for all students with a scientific literacy emphasis. Over 12,000 students in 78 schools have followed this course since September 2003. The development of a detailed teaching programme is an important means of clarifying the meanings and implications of a “scientific literacy” approach. Questionnaire data from teachers at the end of the first and second years of the project (N = 40 and N = 51) show a strongly positive evaluation of the central features of the course design. Teachers perceive the scientific literacy emphasis as markedly increasing student interest and engagement. Key challenges identified are the language and reasoning demands in looking critically at public accounts of science, and the classroom management of more open discussion about science‐related issues.  相似文献

The ubiquitous goals of helping precollege students develop informed conceptions of nature of science (NOS) and experience inquiry learning environments that progressively approximate authentic scientific practice have been long-standing and central aims of science education reforms around the globe. However, the realization of these goals continues to elude the science education community partly because of a persistent, albeit not empirically supported, coupling of the two goals in the form of ‘teaching about NOS with inquiry’. In this context, the present paper aims, first, to introduce the notions of, and articulate the distinction between, teaching with and about NOS, which will allow for the meaningful coupling of the two desired goals. Second, the paper aims to explicate science teachers’ knowledge domains requisite for effective teaching with and about NOS. The paper argues that research and development efforts dedicated to helping science teachers develop deep, robust, and integrated NOS understandings would have the dual benefits of not only enabling teachers to convey to students images of science and scientific practice that are commensurate with historical, philosophical, sociological, and psychological scholarship (teaching about NOS), but also to structure robust inquiry learning environments that approximate authentic scientific practice, and implement effective pedagogical approaches that share a lot of the characteristics of best science teaching practices (teaching with NOS).  相似文献

Globally, science curricula have been described as outdated, and students perceive school science as lacking in relevance. Declines in senior secondary and tertiary student participation in science indicate an urgent need for change if we are to sustain future scientific research and development, and perhaps more importantly, to equip students with the knowledge and skills to make informed decisions related to scientific research. This paper argues that a good starting point would be the inclusion of more contemporary areas of science in middle school curricula. One such area with continually emerging developments is biotechnology. This paper further argues the need for research into the impact of biotechnology education that would allow students to go beyond learning about biotechnological processes and products to explore their benefits and risks through an integrated approach, where biotechnology education were extended to include subject areas beyond science, such as social sciences, health education, and English. Such an approach is important, in light of research that suggests that the general public has a limited understanding of biotechnology and that public dissemination of information is insufficient to allow individuals to make informed decisions about or to develop attitudes towards, the varied applications of biotechnology. If we are to educate students to be tomorrow’s informed decision-makers, we must start by addressing their understanding of and attitudes towards emerging sciences. Further research is needed to broaden our understanding of how to achieve these goals.  相似文献

Holding scientific conceptions and having the ability to accurately predict students’ preconceptions are a prerequisite for science teachers to design appropriate constructivist-oriented learning experiences. This study explored the types and sources of students’ preconceptions of electric circuits. First, 438 grade 3 (9 years old) students were surveyed about their pre-instructional ideas on electric circuits and where they developed these ideas. Then, 76 elementary school teachers with master’s degrees in science education were selected and their content knowledge of electric circuits was documented. Next, they were asked to make predictions about the kind of preconceptions most grade 3 students would have about electric circuits and the most dominant source of these preconceptions. The results revealed that these skilled teachers held scientific conceptions for most of the questions surveyed; however, they inaccurately predicted the types and sources of the students’ prominent alternative preconceptions. Specifically, they underestimated the possibility of students holding scientific concepts and neglected the effect of students’ intuition on their conceptions. Implications for teaching and teacher education are discussed.  相似文献

Research Findings: The study examined the beliefs of kindergarten teachers (K-teachers) regarding the goals of kindergarten. We asked K-teachers to reflect on their own beliefs, their understanding of parents’ beliefs, and their understanding of the beliefs that guide agents of the education system. We further examined differences between K-teachers based on the type of kindergarten in which they worked (religious or secular) and the socioeconomic status of children’s families (middle-high or middle-low). A total of 120 K-teachers responded to closed questionnaires, and 12 teachers also participated in a semistructured interview. The results revealed an incongruence between K-teachers’ perspectives and their understanding of the positions of parents and of agents of the education system. K-teachers evaluated fostering children’s positive self-esteem as the most important goal and promoting literacy and mathematics skills as the least important. They believed, however, that parents and agents of the education system regard children’s advancement in literacy and mathematics skills as the most important goal. Practice or Policy: Recognizing this incongruence facilitates understanding of the rationale behind K-teachers’ actions and their relationships with parents and professional partners. It enables identification of topics that need to be addressed by the professional education community in order to create a dialogue among K-teachers, families, and policymakers.  相似文献

Science learning is inextricably tied to two aspects of students’ lives: literacy and culture. While English Learners (ELs) who speak a non-English native language are typically the focus in this line of scholarly inquiry, deaf and hard-of-hearing (DHH) students occupy a distinct space in this conversation. For DHH learners, literacy levels can be hindered by an early dependence on a more survival-based language learning model that postpones basic scientific inquiry. The vocabulary for curiosity is limited, which in turn affects the educational culture. DHH learners have a unique culture that demands an appropriate science curriculum, which thus far has not been explored or attempted for either DHH learners or their educators. Data collected consisted of interviews with teachers of DHH students, as well as observational data collected from a high-minority urban K-8 school for DHH students. The analysis revealed that, first, many of the teachers had limited preparation to teach science content. Second, DHH teachers used inconsistent instructional strategies ranging from drawing pictures to building models. Third, the modifications provided to DHH science learners were mostly limited to visual support and repetition. Implications for teacher education programs include instruction focused on specific supports for DHH students and co-teaching methods, and deeper investigation of inquiry-based science practices. Implications for classroom practices include providing hands-on, inquiry-based instruction, working closely with parents, and developing students’ and teachers’ understanding of scientific inquiry.

Science literacy includes understanding technology. This raises questions about the role of technology in science education as well as in general education. To explore these questions, this article begins with a brief history of technology education as it relates to science education and discusses how new conceptions of science and technological literacy are moving beyond the dichotomies that formerly characterized the relationship between science and technology education. It describes how Benchmarks for Science Literacy, the National Science Education Standards, and the Standards for Technological Literacy have been making a case for introducing technology studies into general education. Examples of specific technological concepts fundamental for science literacy are provided. Using one example from the design of structures, the article examines how understanding about design (i. e., understanding constraints, trade‐offs, and failures) is relevant to science literacy. This example also raises teaching and learning issues, including the extent to which technology‐based activities can address scientific and technological concepts. The article also examines how research can provide guides for potential interactions between science and technology and concludes with reflections on the changes needed, such as the creation of curriculum models that establish fruitful interactions between science and technology education, for students to attain an understanding of technology. © 2001 John Wiley & Sons, Inc.

This paper reports on a large scale study that investigated the quality of teaching and learning in science in Australian schools. Its purposes were first, to describe ideal practice in the teaching and learning of school science; second, to describe the nature of teaching and learning of science in Australian schools; and third, to make recommendations to move the actual closer to the ideal.Fundamental to the research was the belief that scientific literacy is a high priority for all citizens, helping them to be interested in, and understand the world around them, to be sceptical and questioning of claims made by others about scientific matters, to be able to identify questions, investigate and draw evidence-based conclusions, and to make informed decisions about the environment and their own health and well-being.Based on national and international reports and research literature, and substantial new data collected from teachers, students and other Australian stakeholders in science education, the ideal picture was described in nine themes relating to the curriculum, teaching and learning strategies, professionalism of teachers and their career path, resources and facilities, and the value of science and science education to the community. The actual picture was one of great variability, but overall, it was bleak. The actual curriculum implemented in most schools differs from the intended curriculum, which is focused on developing scientific literacy and helping students progress towards achieving the stated outcomes. Science in primary schools is generally student-centred and activity-based. When students move to high school, many experience disappointment, because the science they are taught is neither relevant nor engaging and does not connect with their interests and experiences. Disenchantment with science is reflected in the decline in science subjects taken by students in upper secondary school. Many science teachers feel undervalued, under-resourced and overloaded with non-teaching duties.The recommendations developed to improve the status and quality of science education were underlain by five fundamental premises: the purpose of science education is to develop scientific literacy, the focus for change is closing the gap between the actual and ideal, teachers are the key to change, change takes time and resources, and collaboration is essential for quality science education. Preliminary recommendations were prepared and scrutinised by members of a government-appointed Steering Committee for the project, critical friends, and teacher focus groups. Recommendations concerning awareness, teachers, resources, assessment, and national collaboration were developed incorporating feedback from the process described, each including a range of suggested actions for implementation that were feasible in the Australian context. If Commonwealth and State governments choose to act on these recommendations, the gap between the actual picture of science teaching and learning in Australia and the ideal will be significantly reduced.  相似文献

Most American colleges and universities offer gateway biology courses to meet the needs of three undergraduate audiences: biology and related science majors, many of whom will become biomedical researchers; premedical students meeting medical school requirements and preparing for the Medical College Admissions Test (MCAT); and students completing general education (GE) graduation requirements. Biology textbooks for these three audiences present a topic scope and sequence that correlates with the topic scope and importance ratings of the biology content specifications for the MCAT regardless of the intended audience. Texts for “nonmajors,” GE courses appear derived directly from their publisher''s majors text. Topic scope and sequence of GE texts reflect those of “their” majors text and, indirectly, the MCAT. MCAT term density of GE texts equals or exceeds that of their corresponding majors text. Most American universities require a GE curriculum to promote a core level of academic understanding among their graduates. This includes civic scientific literacy, recognized as an essential competence for the development of public policies in an increasingly scientific and technological world. Deriving GE biology and related science texts from majors texts designed to meet very different learning objectives may defeat the scientific literacy goals of most schools’ GE curricula.  相似文献

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.  相似文献

Teaching science as explanation is fundamental to reform efforts but is challenging for teachers—especially new elementary teachers, for whom the complexities of teaching are compounded by high demands and little classroom experience. Despite these challenges, few studies have characterized the knowledge, beliefs, and instructional practices that support or hinder teachers from engaging their students in building explanations. To address this gap, this study describes the understandings, purposes, goals, practices, and struggles of one third-year elementary teacher with regard to fostering students' explanation construction. Analyses showed that the teacher had multiple understandings of scientific explanations, believed that fostering students' explanations was important for both teachers and students, and enacted instructional practices that provided opportunities for students to develop explanations. However, she did not consistently take up explanation as a goal in her practice, in part because she did not see explanation construction as a strategy for facilitating the development of students' content knowledge or as an educational goal in its own right. These findings inform the field's understanding of teacher knowledge and practice with regard to one crucial scientific practice and have implications for research on teachers and inquiry-oriented science teaching, science teacher education, and curriculum materials development.  相似文献
