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

This study (a) assessed the influence of three history of science (HOS) courses on college students' and preservice science teachers' conceptions of nature of science (NOS), (b) examined whether participants who entered the investigated courses with a conceptual framework consistent with contemporary NOS views achieved more elaborate NOS understandings, and (c) explored the aspects of the participant HOS courses that rendered them more “effective” in influencing students' views. Participants were 166 undergraduate and graduate students and 15 preservice secondary science teachers. An open‐ended questionnaire in conjunction with individual interviews, was used to assess participants' pre‐ and postinstruction NOS views. Almost all participants held inadequate views of several NOS aspects at the outset of the study. Very few and limited changes in participants' views were evident at the conclusion of the courses. Change was evident in the views of relatively more participants, especially preservice science teachers, who entered the HOS courses with frameworks that were somewhat consistent with current NOS views. Moreover, explicitly addressing certain NOS aspects rendered the HOS courses relatively more effective in enhancing participants' NOS views. The results of this study do not lend empirical support to the intuitively appealing assumption held by many science educators that coursework in HOS will necessarily enhance students' and preservice science teachers' NOS views. However, explicitly addressing specific NOS aspects might enhance the effectiveness of HOS courses in this regard. Moreover, the study suggests that exposing preservice science teachers to explicit NOS instruction in science methods courses prior to their enrollment in HOS courses might increase the likelihood that their NOS views will be changed or enriched as a result of their experiences with HOS. © 2000 John Wiley & Sons, Inc.

Pre‐service teachers face many challenges as they learn to teach in ways that are different from their own educational experiences. Pre‐service teachers often enter teacher education courses with pre‐conceptions about teaching and learning that may or may not be consistent with contemporary learning theory. To build on preservice teachers' prior knowledge, we need to identify the types of views they have when entering teacher education courses and the views they develop throughout these courses. The study reported here focuses specifically on preservice teachers' views of their own students' prior knowledge and the implications these views have on their understanding of the formative assessment process. Sixty‐one preservice teachers were studied from three sections of a science methods course. Results indicate that preservice teachers exhibited a limited number of views about students' prior knowledge. These views tended to privilege either academic or experience‐based concepts for different aspects of formative assessment, in contrast to contemporary perspectives on teaching for understanding. Rather than considering these views as misconceptions, it is argued that it is more useful to consider them as resources for further development of a more flexible concept of formative assessment. Four common views are discussed in detail and applied to science teacher education. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 497–523, 2008  相似文献

This study utilized responses from Taiwanese preservice elementary teachers to describe and analyze their conceptions about the assessment of science learning and the extent that these conceptions were coherent with their views of learning science. A methodological framework of phenomenography was used for the study. The results revealed that the preservice teachers' mode of assessment was coherent with a traditional view of learning but their performance mode of assessment was not well developed. Improving preservice teachers' conception of assessment requires clarifying and reconstructing their conceptions of and coherence between assessment, curriculum, pedagogy, and learning.  相似文献

The purpose of the Gender and Ethnic Equity in Science Education (GEESE) program, conducted during the student-teaching semester, was to provide preservice science teachers with the opportunity to use clinical observations and reflection as vehicles for discovery of the disparate school experiences of the diverse students in their science classrooms. The preservice teachers examined curricular materials in use during their practicum, student and teacher behaviors, the quantity and quality of student–teacher interactions, and grouping and evaluative strategies before attempting self-analysis at the conclusion of the program. Interviews were used as the source of qualitative evidence of change in the preservice teachers' attitudes and teaching behaviors. While students approved of the program initially, they eventually dismissed issues of gender and ethnic equity as critical once they began struggling with the inadequate academic preparation of their students and scant material resources. Ultimately, the preservice teachers identified the GEESE program as useful in that it provided them with specific critical techniques, but inappropriately placed at the conclusion of their professional development sequence. © 1997 John Wiley & Sons, Inc.

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 mixed‐methods investigation compared the relative impacts of instructional approach and context of nature of science instruction on preservice elementary teachers' understandings. The sample consisted of 75 preservice teachers enrolled in four sections of an elementary science methods course. Independent variables included instructional approach to teaching nature of science (implicit vs. explicit) and the context of nature of science instruction (as a stand‐alone topic vs. situated within instruction about global climate change and global warming). These treatments were randomly applied to the four class sections along a 2 × 2 matrix, permitting the comparison of outcomes for each independent variable separately and in combination to those of a control group. Data collection spanned the semester‐long course and included written responses to pre‐ and post‐treatment administrations of the VNOS‐B, semi‐structured interviews, and a variety of classroom artifacts. Qualitative methods were used to analyze the data with the goal of constructing profiles of participants' understandings of the nature of science and of global climate change /global warming (GCC/GW). These profiles were compared across treatments using non‐parametric statistics to assess the relative effectiveness of the four instructional approaches. Results indicated that preservice teachers who experienced explicit instruction about the nature of science made statistically significant gains in their views of nature of science regardless of whether the nature of science instruction was situated within the context of GCC/GW or as a stand‐alone topic. Further, the participants who experienced explicit nature of science instruction as a stand‐alone topic were able to apply their understandings of nature of science appropriately to novel situations and issues. We address the implications of these results for teaching the nature of science in teacher preparation courses. © 2010 Wiley Periodicals, Inc., Inc. J Res Sci Teach 48: 414–436, 2011  相似文献

This study assessed the influence of a 3‐year professional development program on elementary teachers' views of nature of science (NOS), instructional practice to promote students' appropriate NOS views, and the influence of participants' instruction on elementary student NOS views. Using the VNOS‐B and associated interviews the researchers tracked the changes in NOS views of teacher participants throughout the professional development program. The teachers participated in explicit–reflective activities, embedded in a program that emphasized scientific inquiry and inquiry‐based instruction, to help them improve their own elementary students' views of NOS. Elementary students were interviewed using the VNOS‐D to track changes in their NOS views, using classroom observations to note teacher influences on student ideas. Analysis of the VNOS‐B and VNOS‐D showed that teachers and most grades of elementary students showed positive changes in their views of NOS. The teachers also improved in their science pedagogy, as evidenced by analysis of their teaching. Implications for teacher professional development programs are made. © 2006 Wiley Periodicals, Inc.

This study aimed to delineate the factors mediating the translation of preservice teachers' conceptions of the nature of science into instructional planning and classroom practice. Additionally, the study assessed the influence of temporally separating teaching preservice teachers about the nature of science and teaching them how to address it instructionally. This latter intervention was based on the results of a previous investigation. Prior to student teaching, the 13 participants responded to an open‐ended questionnaire designed to assess conceptions of the nature of science. Throughout student teaching, daily lesson plans, classroom videotapes, portfolios, and supervisors' weekly clinical observation notes were collected and searched for explicit instances of nature of science planning and/or instruction. Following student teaching, participants were interviewed to validate their responses to the open‐ended questionnaire, identify factors that mediate the translation of their conceptions of the nature of science into classroom teaching, and explicate their pedagogical preferences for teaching the nature of science. Participants possessed adequate understanding of several aspects of the nature of science and, contrary to the results of the earlier investigation, most did not conflate the nature of science with science processes. Furthermore, several participants explicitly addressed some aspects of the nature of science during classroom instruction. Participants, however, failed to include the nature of science among their instructional objectives and did not make a concerted effort to assess student understandings. © 2000 John Wiley & Sons, Inc.

The purpose of this study was to describe the knowledge base of a group of science teachers in terms of their knowledge of the structure, function, and development of their disciplines, and their understanding of the nature of science. The study also aimed to relate the teachers' knowledge base to their level of education, years of teaching experience, and the class level(s) that they teach. Twenty inservice science teachers were selected to respond to a modified version of the Views on Science–Technology–Society (VOSTS) questionnaire to assess their understanding of the nature of science. The teachers then constructed concept maps and were interviewed. The concept maps were scored and the interviews analyzed to assess teachers' knowledge of the structure, function, and development of their disciplines. The teachers' knowledge base was found to be lacking in all respects. Teachers held several naive views about the nature of science and did not demonstrate adequate knowledge and understanding of the structure, function, and development of their disciplines. Moreover, the teachers' knowledge base did not relate to their years of teaching experience, the class level(s) that they teach, and their level of education. It was reasoned that teacher preparation programs are not helping teachers develop the knowledge base needed for teaching science. © 1997 John Wiley & Sons, Inc.

Practicum experiences in schools are highly valued in science teacher education programs. Yet, there are few studies examining secondary preservice science teachers' practicum classrooms. This mixed-methods study explored secondary preservice science teachers' perceptions of their practicum classroom learning environments, interpreted from an open-ended survey questionnaire, as well as from an adapted version of the Constructivist Learning Environment Survey (CLES; Taylor, Fraser, & Fisher, 1997). Twenty-two preservice teachers within secondary science methods courses volunteered to complete the survey. Qualitative survey findings were corroborated by quantitative results from the CLES survey. Overall, the preservice teachers perceived their practicum classrooms to incorporate some constructivist learning environment factors, but the critical constructivist perspective underpinning the survey was not found. Additionally, innovative practices cogent with these practices were not supported by most of their co-operating teachers. Implications of how preservice education programs can better support prospective science teachers' views and practices during practicum are discussed.  相似文献

The three case studies, drawing on qualitative analysis of surveys, interviews, program artifacts, and classroom observation, describe secondary science preservice teachers' evolving expertise at providing opportunities for linguistically diverse students to learn and demonstrate what they have learned (i.e., equitable assessment). The teachers became more knowledgeable about the role of language in assessment and incorporated scientific discourse while assessing in their teaching practicum. Yet, two tensions emerged, which inform the preparation of future science teachers: (a) should language demands of science assessment be reduced or scaffolded and (b) should language use in science as well as scientific understanding be assessed?  相似文献

The purpose of this case study was to explore the ways in which 3 different informal science experiences in the context of an elementary methods course influenced a group of prospective elementary teachers' ideas about science teaching and learning as well as their understandings about the role of informal science environments to teaching and learning. In order to address this question, data were collected in a period of an academic semester through the following sources: journal entries for each of the 3 experiences, a personal teaching philosophy statement and a 2-hour long semi-structured interview with each of the 12 participants. Open coding techniques were used to analyze the data in order to construct categories and subcategories and eventually to identify emerging themes. The outcomes of the analysis showed that the inclusion of informal science experiences in the context of teacher preparation has the potential to support beginning elementary teachers' development of contemporary ideas about science teaching and learning related to inquiry-based science, the nature of scientific work and the work of scientists, connecting science with everyday life, and making science fun and personally meaningful. These findings are discussed alongside implications for policy, teacher preparation, and research under these themes: (a) addressing reform recommendations; (b) developing positive orientations toward science and science teaching; and (c) constructing understandings about scientists' work.  相似文献

This study explored whether early childhood preservice teachers' concerns about teaching nature of science (NOS) and their intellectual levels influenced whether and how they taught NOS at the preschool and primary (K‐3) levels. We used videotaped classroom observations and lesson plans to determine the science instructional practices at the preschool and primary levels, and to track whether and how preservice teachers emphasized NOS. We used the Stages of Concern Questionnaire (SOCQ) pre‐ and postinternship to determine concerns about NOS instruction, and the Learning Context Questionnaire (LCQ) to determine intellectual levels. We found that neither concerns about teaching NOS nor intellectual level were related to whether and how the preservice teachers emphasized NOS; however, we found that all preservice early childhood teachers began their internships with NOS concern profiles of “worried.” Two preservice teachers' NOS concerns profiles changed as a result of their internships; one to “cooperator” and one to “cooperator/improver.” These two preservice teachers had cooperating teachers who were aware of NOS and implemented it in their own science instruction. The main factors that hindered or facilitated teaching NOS for these preservice teachers were the influence of the cooperating teacher and the use of the science curriculum. The preservice teacher with the cooperating teacher who understood and emphasized NOS herself and showed her how to modify the curriculum to include NOS, was able to explicitly teach NOS to her students. Those in classrooms whose cooperating teachers did not provide support for NOS instruction were unable to emphasize NOS. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47:213–233, 2010  相似文献

In broad terms, this study describes preservice elementary teachers' beliefs, conceptions, and practices during the mathematics methods course and teaching practica of a teacher education program. In particular, the study employs qualitative data to investigate preservice teachers' views of mathematical and pedagogical content knowledge. The study reveals symbiotic relationships between their views of content knowledge and their instructional actions which remain problematic. With unwavering beliefs and practices, and without reconceptualizing their roles as future elementary teachers, at the end of the semester the preservice teachers emerge as poor duplicators of mathematics methods instead of initiators of learning.  相似文献

Since science became part of the core curriculum in England and Wales for children aged five upwards, primary school teachers have moved from widespread diffidence to positions of some confidence and success in teaching it. In the process, their views of the nature of science and the purposes of teaching it can be expected to have developed. The importance of the teacher in relation to the quality of students' learning, and to the ideas about and orientations towards a subject that students develop, is well documented. There are good reasons to believe that teachers' views of the nature of science form part of a ‘hidden curriculum’ in their science teaching: thus, an understanding of them is necessary to an understanding of learners' experiences of science teaching. The research reported explored such views through both case study and survey methodologies. The case studies showed the depth and subtlety of some teachers' views of science. The survey data yielded six factors, explaining 82% of the variance in respondents' views of science, provisionally named scientism, naive empiricism, ‘new-age-ism’, constructivism, pragmatism and scepticism. The views of science expressed by teachers in interview, and those inferred from and made explicit in their practice, were in most cases consistent with their positions on these factors. These enable interesting insights into the representations of science communicated by primary teachers in their science teaching, which could inform curriculum development in relation to the nature of science, at both primary and secondary levels.  相似文献

This study explored preservice elementary teachers' and their mentors' understanding of the essential features of inquiry-based teaching through the use of evidence-based reflection. The web-based video analysis tool (VAT) system was used to support preservice teachers' and mentors' evidence-based reflection during field experiences. Major data sources included VAT reflections and individual interviews. Data analysis indicated that the preservice teachers had been involved in various activities designed to support their understanding of inquiry features in a science methods class; they did not implement all of the features in their actual teaching. Both preservice teachers and mentors had difficulty connecting appropriate inquiry features to each teaching episode, which indicates their lack of understanding of inquiry. Both the preservice teachers and mentors had different levels of understanding for each feature. That is, they tended to understand certain features better than others. They interpreted each feature of inquiry-based science teaching too broadly. They also either had a teacher-centered view or tended to focus on issues unrelated to science teaching.  相似文献

Many science educators, in the US and elsewhere, suppport the idea that all students should have fair and equal opportunities to become scientifically literate through authentic, real problem-based science education. However, this challenge requires teachers to find ways to help all students feel comfortable with, and connected to, science. Despite the general consensus around the ideal of science for all, science teacher education programmes have had little or no impact on preservice teachers' philosophies of teaching and learning, especially as it relates to serving underserved populations in science. In this paper, I explore community service-learning as one way of addressing the multicultural dimension of preservice education with the following three questions: In what ways does involving pre-service science teachers in community service-learning influence their views on multicultural science education, in theory and practice? What qualities of community service-learning make multicultural science education a realistic objective? How might service-learning be used to push our collective understanding of what an inclusive and liberatory multicultural science teaching practice could be? I explore these questions and propose further areas of research by using a case study involving service-learning from my own teaching-research with preservice students.  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.

This study examines Turkish pre-service science teachers' understanding of science concepts and their confidence in its teaching. A total of 299 senior science education major students participated in the study. Data collection instruments included the Science Concepts Test, and the Science Teaching Efficacy Belief Instrument. Although findings of the study indicated that majority of the participants held misconceptions concerning fundamental science concepts, they generally felt confident about teaching it. The relationship that might exist among pre-service science teachers' confidence in their effectiveness in teaching and the number of the science courses completed in university is examined.  相似文献
