In this paper I discuss the tension created by religion and science in one student’s understanding of knowledge and truth by exploring two questions: “How do individuals accommodate their religious beliefs with their understanding of science?” and “How does religious knowledge interact with scientific knowledge to construct meaning?” A constructivist framework sheds light on the answers to both questions in the context of process and product. 相似文献

Recent developments in the field of genomics will impact the daily practice of biology teachers who teach genetics in secondary education. This study reports on the first results of a research project aimed at enhancing biology teacher knowledge for teaching genetics in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of such a situated learning approach. What content knowledge do biology teachers need for teaching genetics in the personal health context of genetic testing? This study describes the required content knowledge by exploring the educational practice and clinical genetic practices. Nine experienced teachers and 12 respondents representing the clinical genetic practices (clients, medical professionals, and medical ethicists) were interviewed about the biological concepts and ethical, legal, and social aspects (ELSA) of testing they considered relevant to empowering students as future health care clients. The ELSA suggested by the respondents were complemented by suggestions found in the literature on genetic counselling. The findings revealed that the required teacher knowledge consists of multiple layers that are embedded in specific genetic test situations: on the one hand, the knowledge of concepts represented by the curricular framework and some additional concepts (e.g. multifactorial and polygenic disorder) and, on the other hand, more knowledge of ELSA and generic characteristics of genetic test practice (uncertainty, complexity, probability, and morality). Suggestions regarding how to translate these characteristics, concepts, and ELSA into context-based genetics education are discussed. 相似文献

Recently, theorists have raised concerns that pedagogical content knowledge (PCK) has become “a stale metaphor” that disregards diversity and equity, offers little to help teachers address students’ misconceptions, and portrays knowledge as “in the head” versus in practice. We refute these notions using grounded theory to specify ways one 7th-grade science teacher enacted PCK to advance student learning. With the definition of PCK as knowledge at the intersection of content and teaching, we utilised a framework for science PCK to explore instructional decision-making. Interviews conducted over three years revealed specific ways the teacher enacted PCK by designing and delivering instruction built on each of the seven conceptual science PCK components. The teacher enacted PCK to plan and deliver instruction that was responsive, adaptive, and considerate of changing needs of students and the changing classroom landscape. She infused PCK into instructional decision-making, instructional interactions, and mentoring of a student teacher, modelling the translation of educational theory into practice and habits of mind necessary for expert teaching. This enactment actively refutes Settlage’s critiques, and depicts PCK as a vibrant and effective stance for teaching that enhances learning. 相似文献

The Next Generation Science Standards (NGSS) strives to shift science learning from the teacher as a single cognitive agent, to a classroom community in which participants are working together in directing the classroom's communal knowledge to figure out questions about how phenomena occur, and building, testing, and refining their ideas to address those questions. To achieve this type of classroom environment, teachers should attend to students' knowledge and ideas and pay attention to how students are located within teacher-led interactions, such as being positioned as active discussants or designated listeners. In this study, we explore if and how this is occurring in the NGSS era. We used a naturalistic inquiry to explore how an experienced first-grade teacher used a new NGSS-aligned unit that called for students to use the science and engineering practices (SEP) to build content knowledge. We used a macro-analytic lens to answer the research question “how are class discussions shaped to address the SEP”? We used a micro-analytic lens to answer the research question “how are students positioned during these science discussions in this classroom?” Evidence suggests that the teachers' whole class discussions incorporated and involved the SEP which were specified in the unit lessons for content learning. However, on a micro-analytic level, we found that few students were positioned as active discussants. The teacher heavily relied on those students who could provide succinct and clearly relevant answers while positioning the remainder of the students as silent spectators. Implications from this research suggest that not only new NGSS curriculum materials need to focus on what students should know and do but they also need to address heuristics for teachers that show them how to position all of their students as active doers of science so all students have opportunities to build deeper, core science knowledge. 相似文献

The purpose of this study is to interpret and qualitatively characterise the content in some research articles and evaluate cases of possible difference in meanings of the gene concept used. Using a reformulation of Hirst’s criteria of forms of knowledge, articles from five different sub-disciplines in biology (transmission genetic, molecular biology, genomics, developmental biology and population genetics) were characterised according to knowledge project, methods used and conceptual contexts. Depending on knowledge project, the gene may be used as a location of recombination, a target of regulatory proteins, a carrier of regulatory sequences, a cause in organ formation or a basis for a genetic map. Methods used range from catching wild birds and dissecting beetle larvae to growing yeast cells in 94 small wells as well as mapping of recombinants, doing statistical calculations, immunoblotting analysis of protein levels, analysis of gene expression with PCR, immunostaining of embryos and automated constructions of multi-locus linkage maps. The succeeding conceptual contexts focused around concepts as meiosis and chromosome, DNA and regulation, cell fitness and production, development and organ formation, conservation and evolution. These contextual differences lead to certain content leaps in relation to different conceptual schemes. The analysis of the various uses of the gene concept shows how differences in methodologies and questions entail a concept that escapes single definitions and “drift around” in meanings. These findings make it important to ask how science might use concepts as tools of specific inquiries and to discuss possible consequences for biology education. 相似文献

Particular social aspects of the nature of science (NOS), such as economics of, and entrepreneurship in science, are understudied in science education research. It is not surprising then that the practical applications, such as lesson resources and teaching materials, are scarce. The key aims of this article are to (a) synthesize perspectives from the literature on economics of science (EOS), entrepreneurship, NOS, and science education in order to have a better understanding of how science works in society and (b) illustrate how such a synthesis can be incorporated in the practice of science education. The main objectives of this article are to (1) argue for the role and inclusion of EOS and entrepreneurship in NOS and re-define entrepreneurship in the NOS context; (2) explore the issues emerging in the “financial systems” of the Family Resemblance Approach (FRA) to NOS and propose the inclusion of contemporary aspects of science, such as EOS and entrepreneurship, into NOS; (3) conceptualize NOS, EOS, and entrepreneurship in a conceptual framework to explain how science works in the society; and (4) transform the theoretical knowledge of how science operates in society into practical applications for science teaching and learning. The conceptual framework that we propose illustrates the links between State, Academia, Market and Industry (the SAMI cycle framework). We suggest practical lesson activities to clarify how the theoretical discussions on the SAMI cycle framework can be useful and relevant for classroom practice. In this article, science refers to physics, chemistry, and biology. However, we also recommend an application of this framework to other sciences to reveal their social-institutional side. 相似文献

There is emerging interest on the interactions between modelling and argumentation in specific contexts, such as genetics learning. It has been suggested that modelling might help students understand and argue on genetics. We propose modelling gene expression as a way to learn molecular genetics and diseases with a genetic component. The study is framed in Tiberghien’s (2000) two worlds of knowledge, the world of “theories & models” and the world of “objects & events”, adding a third component, the world of representations. We seek to examine how modelling and argumentation interact and connect the three worlds of knowledge while modelling gene expression. It is a case study of 10th graders learning about diseases with a genetic component. The research questions are as follows: (1) What argumentative and modelling operations do students enact in the process of modelling gene expression? Specifically, which operations allow connecting the three worlds of knowledge? (2) What are the interactions between modelling and argumentation in modelling gene expression? To what extent do these interactions help students connect the three worlds of knowledge and modelling gene expression? The argumentative operation of using evidence helps students to relate the three worlds of knowledge, enacted in all the connections. It seems to be a relationship among the number of interactions between modelling and argumentation, the connections between world of knowledge and students’ capacity to develop a more sophisticated representation. Despite this is a case study, this approach of analysis reveals potentialities for a deeper understanding of learning genetics though scientific practices. 相似文献

Cognitive Research and Elementary Science Instruction: From the Laboratory,to the Classroom,and Back 总被引：1，自引：0，他引：1
Can cognitive research generate usable knowledge for elementary science instruction? Can issues raised by classroom practice drive the agenda of laboratory cognitive research? Answering yes to both questions, we advocate building a reciprocal interface between basic and applied research. We discuss five studies of the teaching, learning, and transfer of the “Control of Variables Strategy” in elementary school science. Beginning with investigations motivated by basic theoretical questions, we situate subsequent inquiries within authentic educational debates—contrasting hands-on manipulation of physical and virtual materials, evaluating direct instruction and discovery learning, replicating training methods in classroom, and narrowing science achievement gaps. We urge research programs to integrate basic research in “pure” laboratories with field work in “messy” classrooms. Finally, we suggest that those engaged in discussions about implications and applications of educational research focus on clearly defined instructional methods and procedures, rather than vague labels and outmoded “-isms.” 相似文献

Teachers need to know a great deal, in many areas and in multiple ways. Teacher knowledge is a complex tapestry, and teachers must successfully weave the multiple threads. In this article, I present a conceptualisation of teacher knowledge that provides a framework for describing the complexity of teacher knowledge. The framework describes three ways of knowing: “knowing how,” “knowing why,” and “knowing what” and then applies these three knowledge discourses across six domains of teacher knowledge. The framework was developed from a study of 14 teachers in their first year of teaching, and in this article the framework is applied to their experiences to illustrate specific gaps in their teacher knowledge. It is proposed that this conceptualisation of teacher knowledge allows those involved in teacher education and induction to more clearly identify professional learning needs and develop their programmes with specificity. 相似文献

In this paper, we build on growing conversations centered around indigenous knowledge and its parity with various ways of knowing nature including traditional ecological knowledge, indigenous ways of living in nature, a Japanese way of knowing seigo-shizen, and Eurocentric sciences. We situate our discussion in Philippine postcolonial realities, where categorical boundaries are blurred, and any attempt to create culturally relevant preservice science teacher preparation will create confusions and tensions between/among/within abovementioned discourses. The Philippines is a highly colonized country—physically, for more than 300 hundred years, and mentally, after our colonizers have long gone. The marks of colonization are still present in our consciousness, in our current local knowledge, and in our ways of living with nature. In the attempt to create a “third space” for culturally relevant science teacher preparation, tensions are highlighted and categorical boundaries are troubled. Where is science? Which one is indigenous or neo-indigenous? Which one is Filipino? Which one is foreign? Which one is ours? Which one is borrowed? These tensions and insights are highlighted through analysis of narratives drawn from interviews with and written outputs of prospective science teachers, as they attempted to make sense of the local knowledge of residents of a rural coastal village in the Philippines during Community Immersion, a community-centered, early field experience in science teacher preparation. 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

In general, mathematical representations such as formulae, numbers, and graphs are the inseparable components in science used to better describe or explain scientific phenomena or knowledge. Regardless of their necessity and benefit, science seems to be difficult for some students, as a result of the mathematical representations and problem solving used in scientific inquiry. In this regard, several studies have attributed students’ decreasing interest in science to the presence of these mathematical representations. In order to better understand student learning difficulties caused by mathematical components, the current study investigates student understanding of a familiar science concept and its mathematical component (pH value and logarithms). Student responses to a questionnaire and a follow-up interview were examined in detail. “Measure” and “concentration” were key criteria for students’ understanding of pH values. In addition, only a few students understood logarithms on a meaningful level. According to students’ understanding of scientific phenomena and mathematical structures, five different student models and the critical features of each type were identified. Further analysis revealed the existence of three domains that characterize these five types: object, operation, and function. By suggesting the importance of understanding scientific phenomena as a “function,” the current study reveals what needs to be taught and emphasized in order to help students obtain a level of scientific meaning that is appropriate for their grade. 相似文献

Is there a place for Indigenous Knowledge in the science curriculum for a Zulu community in rural Kwa-Zulu Natal, South Africa? This article argues “yes,” based on a participative research and development project that discovered relevant science learning in a Zulu community. Among community concerns for relevant factual and performative knowledge, we found that culture and worldview are critical to community identity, to visioning educational outcomes, and to learning in school science. Cultural practices may contribute to pedagogy and curriculum; curriculum, in turn, may affirm cultural practices. Further, worldview needs to be understood as an aspect of knowledge creation. By understanding key aspects of an African worldview, science educators can contribute to both meaningful science education and community well-being. By fostering culture and worldview, a rural community can make a unique contribution to science education. 相似文献

This general paper reports on the problems of intruding “modernity” into schools, both secondary and tertiary. Why? How? Various possibilities are investigated at different levels. The fundamental principle remains the opening of the school towards the outside world. The first step in the right direction is teacher training and in fact training for the science of tomorrow. Is it possible? Perhaps, but with the possibilities of modern technology (scientific and educational) the principle of the “great father” must be eliminated and knowledge must have a new definition. 相似文献

This study situated in a Southern resegregated Black middle school involved four Black teachers and two White science educators’ use of photonarratives to envision culturally relevant science pedagogy. Two questions guided the study: (1) What community referents are important for conceptualizing culturally relevant practices in Black science classrooms? and (2) How do teachers’ photonarratives serve to open conversations and notions of culturally relevant science practices? The research methodologically drew upon memory-work, Black feminism, critical theory, visual methodology, and narrative inquiry as “portraiture.” Issues of positionality and identity proved to be central to this work, as three luminaries portray Black teachers’ insights about supports and barriers to teaching and learning science. The community referents identified were associated with church and its oral traditions, inequities of the market place in meeting their basic human needs, and community spaces. 相似文献

Despite the ubiquity of the term “inquiry” in science education literature, little is known about how teachers conceptualize inquiry, how these conceptions are formed and reinforced, how they relate to work done by scientists, and if these ideas about inquiry are translated into classroom practice. This is a multicase study in which 14 preservice secondary science teachers developed their own empirical investigations—from formulating questions to defending results in front of peers. Findings indicate that participants shared a tacit framework of what it means to “do science” which shaped their investigations and influenced reflections on their inquiries. Some facets of the participants' shared model were congruent with authentic inquiry; however, the most consistent assumptions were misrepresentations of fundamental aspects of science: for example, that a hypothesis functions as a guess about an outcome, but is not necessarily part of a larger explanatory system; that background knowledge may be used to provide ideas about what to study, but this knowledge is not in the form of a theory or other model; and that theory is an optional tool one might use at the end of a study to help explain results. These ideas appear consistent with a “folk theory” of doing science that is promoted subtly, but pervasively, in textbooks, through the media, and by members of the science education community themselves. Finally, although all participants held degrees in science, the participants who eventually used inquiry in their own classrooms were those who had significant research experiences in careers or postsecondary study and greater science‐content background. © 2004 Wiley Periodicals, Inc.

Critique is central to the development of scientific knowledge. From a cognitive perspective, critique can be used to enhance understanding. From a social perspective, critique serves to maintain the standards of a professional field. In science education, it is of tremendous value to diagnose and nurture students’ critical knowledge. How students develop and apply criteria for critique, however, remains unclear. What factors influence students’ performance of critique, and how can educators incorporate technology-enhanced scaffolding strategies to help diagnose and nurture students’ critical knowledge? In this paper, I define critical knowledge as the criteria people use to evaluate other knowledge, the ability to use these criteria across contexts, and the reflective understanding of such processes. Building on existing literature, I develop a conceptual framework that describes the components and processes involved in a critique activity. Using this framework, I discuss the application of technology-enhanced scaffolding strategies to facilitate critique activities in science classrooms. 相似文献

A stand‐alone online teaching module was developed to cover an area of musculoskeletal anatomy (structure of bone) found to be difficult by students. The material presented in the module was not formally presented in any other way, thus providing additional time for other curriculum components, but it was assessed in the final examination. The module was developed using “in‐house” software designed for academics with minimal computer experience. The efficacy and effectiveness of the module was gauged via student surveys, testing student knowledge before and after module introduction, and analysis of final examination results. At least 74% of the class used the module and student responses were positive regarding module usability (navigation, interaction) and utility (learning support). Learning effectiveness was demonstrated by large significant improvements in the post‐presentation test scores for “users” compared with “non‐users” and by the percentage of correct responses to relevant multiple choice questions in the final examination. Performance on relevant short answer questions in the final examination was, on average, comparable to that for other components. Though limited by study structure, it was concluded that the module produced learning outcomes equivalent to those generated by more traditional teaching methods. This “Do‐It‐Yourself” e‐learning approach may be particularly useful for meeting specific course needs not catered for by commercial applications or where there are cost limitations for generation of online learning material. The specific approaches used in the study can assist in development of effective online resources in anatomy. Anat Sci Educ 6: 107–113. © 2012 American Association of Anatomists. 相似文献
