Self-efficacy beliefs that relate to teachers’ motivation and performance have been an important area of concern for preservice teacher education. Research suggests high-quality science coursework has the potential to shape preservice teachers’ science self-efficacy beliefs. However, there are few studies examining the relationship between science self-efficacy beliefs and science content knowledge. The purpose of this mixed methods study is to investigate changes in preservice teachers’ science self-efficacy beliefs and science content knowledge and the relationship between the two variables as they co-evolve in a specialized science content course. Results from pre- and post-course administrations of the Science Teaching Efficacy Belief Instrument-B (Bleicher, 2004) and a physical science concept test along with semi-structured interviews, classroom observations and artifacts served as data sources for the study. The 18 participants belonged to three groups representing low, medium and high initial levels of self-efficacy beliefs. A repeated measures multivariate analysis of variance design was used to test the significance of differences between the pre- and post-surveys across time. Results indicated statistically significant gains in participants’ science self-efficacy beliefs and science conceptual understandings. Additionally, a positive moderate relationship between gains in science conceptual understandings and gains in personal science teaching efficacy beliefs was found. Qualitative analysis of the participants’ responses indicated positive shifts in their science teacher self-image and they credited their experiences in the course as sources of new levels of confidence to teach science. The study includes implications for preservice teacher education programs, science teacher education, and research.  相似文献

Across the globe, governments, industry and educationalists are in agreement that more needs to be done to increase and broaden participation in post-16 science. Schools, as well as teachers, are seen as key in this effort. Previous research has found that engagement with science, inclination to study science and understanding of the value of science strongly relates to a student's science capital. This paper reports on findings from the pilot year of a one-year professional development (PD) programme designed to work with secondary-school teachers to build students’ science capital. The PD programme introduced teachers to the nature and importance of science capital and thereafter supported them to develop ways of implementing science capital-building pedagogy in their practice. The data comprise interviews with the participating teachers (n?=?10), observations of classroom practices and analyses of the teachers’ accounts of their practice. Our findings suggest that teachers found the concept of science capital to be compelling and to resonate with their own intuitive understandings and experiences. However, the ways in which the concept was operationalised in terms of the implementation of pedagogical practices varied. The difficulties inherent in the operationalisation are examined and recommendations for future work with teachers around the concept of science capital are developed.  相似文献

This study explores American and Greek primary pupils’ visual images of scientists by means of two nonverbal data collection tasks to identify possible convergences and divergences. Specifically, it aims to investigate whether their images of scientists vary according to the data collection instrument used and to gender. To this end, 91 third-grade American (N = 46) and Greek (N = 45) pupils were examined. Data collection was conducted through a drawing task based on Chambers (1983) ‘Draw-A-Scientist-Test’ (DAST) and a picture selection task during which the children selected between 14 pairs of illustrations those that were most probable to represent scientists. Analysis focused on stereotype indicators related with scientists’ appearance and work setting. Results showed that the two groups’ performance varied significantly across the tasks used to explore their stereotypic perceptions, although the overall stereotypy was not differentiated according to participants’ ethnic group. Moreover, boys were found to use more stereotypic indicators than girls, while the picture selection task elicited more stereotypic responses than the drawing task. In general, data collected by the two instruments revealed convergences and divergences concerning the stereotypic indicators preferred. Similarities and differences between national groups point to the influence of a globalized popular culture on the one hand and of the different sociocultural contexts underlying science curricula and their implementation on the other. Implications for science education are discussed.  相似文献

Capitalizing on the comments made by teachers on videos of exemplary science teaching, a video-based survey instrument on the topic of ‘Density’ was developed and used to investigate the conceptions of good science teaching held by 110 teachers and 4,024 year 7 students in Hong Kong. Six dimensions of good science teaching are identified from the 55-item questionnaire, namely, ‘focussing on science learning’, ‘facilitating students’ understanding’, ‘encouraging students’ involvement’, ‘creating conducive environment’, ‘encouraging active experimentation’ and ‘preparing students for exam (PSE)’. Significant gaps between teachers’ and students’ conceptions on certain dimensions have been revealed. The inconsistency on the dimension ‘PSE’ is particularly evident and possible reasons for the phenomenon are suggested. This study raises the important questions of how the gap can be addressed, and who is to change in order to close the gaps. Answers to these questions have huge implications for teacher education and teacher professional development.  相似文献

To gain a better understanding of teachers’ beliefs about teaching, as compared with their in-reality classroom practices, case studies were constructed with four science teachers in different schools in Egypt. The main aims of this article were to provide an answer to the research question, ‘To what extent do science teachers’ beliefs correspond to their practices?’ and to explore the contextual factors that can explain the difference, the consistency or inconsistency, between teachers' beliefs and practices. The study collected data for each teacher using semi-structured interviews, notes taken while observing classes, and teachers’ notes, journals, and lesson plans concerned with STS lessons. The data were analysed using the constant comparative method around common themes, which were identified as distinctive features of teachers’ beliefs; these same themes were then compared with their practices. Results showed that a few of the in-service science teachers’ pedagogical beliefs aligned with constructivist philosophy. Some of the teachers’ beliefs were consistent with their practices, especially the traditional beliefs, while some of teachers’ practices were conflicted with their beliefs in different contexts.  相似文献

The introduction of standards into the education system poses numerous challenges and difficulties. As with any change, plans should be made for teachers to understand and implement the standards. This study examined science teachers’ perceptions of the effectiveness of the standards for teaching and learning, and the extent and ease/difficulty of implementing science standards in different grades. The research used a mixed methods approach, combining qualitative and quantitative research methods. The research tools were questionnaires that were administered to elementary school science teachers. The majority of the teachers perceived the standards in science as effective for teaching and learning and only a small minority viewed them as restricting their pedagogical autonomy. Differences were found in the extent of implementation of the different standards and between different grades. The teachers perceived a different degree of difficulty in the implementation of the different standards. The standards experienced as easiest to implement were in the field of biology and materials, whereas the standards in earth sciences and the universe and technology were most difficult to implement, and are also those evaluated by the teachers as being implemented to the least extent. Exposure of teachers’ perceptions on the effectiveness of standards and the implementation of the standards may aid policymakers in future planning of teachers’ professional development for the implementation of standards.  相似文献

This paper reports research from a three-year Australian science teacher professional learning project, the Science Teaching and Learning (STaL) Project, in which groups of science teacher participants (across years K – 12) worked with academics over a one-year period as teacher researchers. Through reflecting on their experiences within the STaL Project and collecting data from their classrooms related to specific science teaching concerns, teacher participants constructed cases around particular aspects of their professional learning. The cases that these participants developed elicited rich insights into their teaching and their students’ learning of science. This paper discusses how the cases were developed by the teacher researcher participants and uses exemplars as a way of illustrating the nature of the professional knowledge developed.  相似文献

Misconceptions about climate change science are pervasive among the US public. This study investigated the possibility that these misconceptions may be reflective of science teachers’ knowledge and teaching of climate change science. Florida and Puerto Rico secondary science teachers who claim to teach extensively about climate change were surveyed in regard to their conceptions of climate change science and the climate change-related topics they teach. Results show that many teachers hold naïve views about climate change (e.g. that ozone layer depletion is a primary cause of climate change) and climate change science (e.g. that it must be based on controlled experiments for it to be valid). In addition, teachers in both groups neglect crucial topics such as how evidence for climate change is developed and the social, political, and economic dimensions of climate change. Our results suggest the need for teachers to understand how to teach climate change and the nature of climate change science using authentic contexts that promote effective socioscientific decision-making and climate change mitigation.  相似文献

This article presents the results of a mixed methods study that used the Draw-a-Scientist Test as a visual tool for exploring preservice teachers’ beliefs about scientists. A questionnaire was also administered to 165 students who were enrolled in elementary (K–8) and secondary (8–12) science methods courses. Taken as a whole, the images drawn by preservice teachers reflected the stereotype of a scientist as a man with a wild hairdo who wears a lab coat and glasses while working in a laboratory setting. However, results indicated statistically significant differences in stereotypical components of representations of scientists depending on preservice teachers’ program and previous science experiences. Post degree students in secondary science methods courses created images of scientists with fewer stereotypical elements than drawings created by students in the regular elementary program.  相似文献

Recently, single-sex classes within public coeducational schools have proliferated across the USA; yet, we still know little about whether and how single-sex science classes influence adolescents’ attitude and affect toward science. This exploratory study expands upon our current understanding by investigating the extent in which female and male students’ enrollment in either single-sex or coeducational science classrooms may influence their academic self-concept in science. Utilizing a quasi-experimental research design, findings suggest that being enrolled in single-sex science classrooms influence how students in this study perceive their abilities to perform and learn in science, particularly for females in single-sex science classrooms.  相似文献

Based on our research on two Athenian daily newspapers for the first decade of the twentieth century, we present some historiographical reflections concerning the role of the daily press in the circulation of scientific knowledge, ideas and practices. From the wealth of material provided, we examine some of the ways in which scientific and technical knowledge was made available to a wider public and contributed to the creation of a general scientific literacy. Although Greece has never been in the forefront of scientific and technological research, the vast amount of newspaper articles on science and technology, but also references to science and technology in other kind of articles, show how discussions on science and technology become part of daily life in order to serve various agendas. Since newspapers address a very wide and diverse public on a daily basis they become privileged media not only for understanding the role science and technology played in the formation of modern societies, but also for examining the values and ideas attached to them and communicated to a wider public.  相似文献

Science and technology translation involves various industries and professions,with its own system of terminology and unique language features.For a translator,who is not a professional scientist or technician,it seems to be difficult to do science and technology translation accurately and properly.Consequently,it is necessary for the translator to give play to his subjectivity when translating science and technology documents or related interpretation:searching for related data to replenish necessary professional knowledge,consulting with professional technicians actively to clarify the jargon and common sayings,and thinking critically to scrutiny the source text.  相似文献

First-Year College Students’ Conflict with Religion and Science   总被引:1,自引:1,他引:0  
This study took place during a First Year Seminar course where 20 incoming college freshmen studied the central topic of the nature of science within the context of biological evolution. The instructor researched students’ understandings in the nature of science as they progressed through the course by examining a variety of qualitative and quantitative data including class writings, pre- and post-test selected items from the VOSTS (Views on Science-Technology-Society), and interviews. The intended outcomes of the course were to reduce the number of student misconceptions in the nature of science and to ease student apprehension when learning about evolution. Data were analyzed to determine whether students were moving toward a more generally accepted idea of the nature of science or toward another type of misconception.  相似文献

There is a current national emphasis on science, technology, engineering, and mathematics (STEM). Additionally, many states are transitioning to the Next Generation Science Standards (NGSS), which encourage teachers to incorporate engineering in science classrooms as well as have their students learn science by doing science. Methods courses are also shifting to adequately prepare preservice science teachers in these areas. This study examines preservice science teachers’ pre- and post-ideal inquiry-based lesson plan scenarios before and after intervention in their Secondary Science Methods I and II courses. These preservice science teachers participated in a variety of opportunities to practice authentic science inquiry (ASI) pedagogical techniques as well as integrated STEM topics, with a particular emphasis on computer programming throughout their 80 h of Methods instruction. ASI is a type of inquiry where students learn science by conducting science research in a grade-appropriate manner. Thirty-eight preservice teachers’ scenarios were analyzed using a rubric from Spuck (2014) to determine the degree to which the ten components of ASI were included in scenarios pre- to post-instruction. Trends in ASI component inclusion are discussed. These findings indicate that preservice science teachers are proficient at writing inquiry-based lessons where they planned opportunities for their future students to collaborate, use scientific instrumentation, and collect and analyze data, but need additional support with developing student activities where students create testable questions, revise their question and methods, participate in peer review, and disseminate their results to their peers or the larger scientific community. Overall, the results suggest Methods instruction should reinforce preservice teachers’ focus on planning lessons which include opportunities for all ASI components. Interventions in the aforementioned areas of weak inclusion may be beneficial to preservice teachers.  相似文献

This preliminary ethnographic investigation focused on how Indigenous traditional wisdom can be incorporated into school science and what students learned as a result. Participants included community elders and knowledge keepers, as well as 4th grade (10-year-old) students, all of Amis ancestry, an Indigenous tribe in Taiwan. The students?? non-Indigenous teacher played a central role in developing a science module ??Measuring Time?? that combined Amis knowledge and Western science knowledge. The study identified two cultural worldview perspectives on time; for example, the place-based cyclical time held by the Amis, and the universal rectilinear time presupposed by scientists. Students?? pre-instructional fragmented concepts from both knowledge systems became more informed and refined through their engagement in ??Measuring Time??. Students?? increased interest and pride in their Amis culture were noted.  相似文献

In recent years, there has been an increasing interest among educational researchers in exploring the relationships between learners’ epistemological beliefs and their conceptions of learning. This study was conducted to investigate these relationships particularly in the domain of science. The participants in this study included 407 Taiwanese college science‐major students. All of them responded to two major questionnaires, one assessing their scientific epistemological beliefs (SEBs) and the other one probing their conceptions of learning science (COLS). The SEB questionnaire included four factors: “certainty,” “source,” “development,” and “justification” of science knowledge. The COLS survey consisted of six factors in a hierarchical order, that is, learning science as “memorizing,” “preparing for tests,” “calculating and practicing,” “increasing one’s knowledge,” “application,” and “understanding and seeing in a new way.” The students’ confidence and interest toward learning science were also assessed by additional questionnaire items. Stepwise regression analyses, in general, showed coherence between students’ SEBs and their COLS, indicating that the sophistication of SEBs was consistent with less agreement with lower‐level COLS (such as “memorizing” and “preparing for tests”) as well as more agreement with higher‐level COLS (such as “understanding and seeing in a new way”). However, the SEB’s “justification” factor was positively related to almost all of COLS factors from the lower‐level to higher‐level. This study finally found that among all of the SEB and COLS factors, the “preparing for tests” factor in COLS was the solely significant variable for predicting students’ interest in science and confidence toward learning science.  相似文献

The interrelationship between senior high school students’ science achievement (SA) and their self‐confidence and interest in science (SCIS) was explored with a representative sample of approximately 1,044 11th‐grade students from 30 classes attending four high schools throughout Taiwan. Statistical analyses indicated that a statistically significant correlation existed between students’ SA and their SCIS with a moderate effect size; the correlation is even higher with almost large effect sizes for a subsample of higher‐SCIS and lower‐SCIS students. Results of t‐test analysis also revealed that there were significant mean differences in students’ SA and their knowledge (including physics, chemistry, biology, and earth sciences subscales) and reasoning skill subtests scores between higher‐SCIS and lower‐SCIS students, with generally large effect sizes. Stepwise regression analyses on higher‐SCIS and lower‐SCIS students also suggested that both students’ SCIS subscales significantly explain the variance of their SA, knowledge, and reasoning ability with large effect sizes.  相似文献
