A 30-item questionnaire was designed to determine Omani science teachers’ attitudes toward teaching science and whether or not these attitudes differ according to gender and teaching experiences of teachers. The questionnaire items were divided into 3 domains: classroom preparation, managing hands-on science, and development appropriateness. The questionnaire was administered to 139 randomly selected science teachers who teach science in grades 5–10. The sample consisted of 72 male teachers and 67 female teachers, 57 teachers with teaching experience between 1 and 5 years and 82 teachers with teaching experience of 6 and more years. The sample was selected from 7 schools in 1 Educational Governorate in the Sultanate of Oman. The questionnaire reliability was calculated by an internal consistency method, using Cronbach’s alpha, which gave the value of 0.73 for all the items. The findings indicated that science teachers’ attitudes toward teaching science were positive. Furthermore, the results showed that there were statically significant differences in teachers’ attitudes due to gender in favor of the female teachers and in teaching experience in favor of teachers with long experience. The study proposed some recommendations to improve the science teachers’ attitude, especially male teachers towards science teaching. Paying more attention to in-service professional development programs, encouraging new teachers to attend some classes to observe experienced colleagues, and finally rewarding teachers morally, socially, and financially are some of these recommendations.  相似文献

This study explored views held by pre-service and in-service science teachers regarding the nature of science and technology particularly: (a) the characteristics of science and technology; (b) the aim of science and scientific research; (c) the characteristics of scientific knowledge and scientific theories; and (d) the relationship between science and technology. The views held by science teachers at pre-service and in-service levels were assessed using a questionnaire. The findings revealed that generally science teachers at both pre-service and in-service levels showed similar views in relation to the nature of science and technology. While the participants displayed mix views regarding science as content oriented or process oriented, technology was viewed as an application of science. Implications of these views for classroom teaching and learning are presented.  相似文献

This study aims to explore preschool teachers’ attitudes toward science teaching and its impact on classroom practices through the frequency of science activities provided in the classroom. In addition, the study investigates if their attitudes are related to factors such as educational level, years of teaching experience, and the school type they work in. The present research was conducted with 292 preschool teachers who work in public and private schools in different districts of Ankara, Turkey. The data were collected by administering the Early Childhood Teachers’ Attitudes toward Science Teaching Scale. Our analyses indicate that there is a significant but weak link between preschool teachers’ attitudes toward science teaching and the frequency of science activities that they provide in the classroom. Further, while teachers’ characteristics such as educational level and experience are found to play an insignificant role on the overall measures of the scale, type of school appears to be a major factor in explaining the attitudes toward science teaching.  相似文献

This study investigated contextual changes in perceptions of science teaching self-efficacy through pre-, post- and retrospective administrations of the Science Teaching Expectancy Belief Instrument (STEBI-B) among preservice elementary teachers when exposed to a science teaching methods course. Findings revealed that the number of postsecondary science courses completed, and prior school science experiences had a significant main effect on personal science teaching efficacy (PSTE) but not science teaching outcome expectancy (STOE). There was no evidence for significant interaction effects between variables on both efficacy subscales. The implications of this study relate to organization, structure, and dynamics of elementary science teacher preparation.  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

The purpose of this study was to obtain data on United States K-5 elementary school teachers’ self-reported instructional practices with graphical representations. Via an electronic survey, 388 elementary teachers, from throughout the US, reported about their teaching of the interpretation and the production of graphics within science. The main findings indicate that: (1) pointing to or referring to graphical representations in books (92% of respondents) was the most frequently used instructional practice across the disciplines and grade levels; (2) five of nine graphical representations (over 90%) were more frequently used in science instruction than in other content areas, and (3) students’ graphical productions involving drawings, labeling, and oral and written explanations were very infrequent. The findings indicate that while teachers may tacitly use graphics within science instruction, they may not be explicitly teaching about this visual form of communication.  相似文献

This research examines the problems that religious Jewish science teachers in Israeli high schools have in coping with science subjects (such as geological time) which conflict with their religious beliefs. We do this by characterizing the philosophical approaches within Judaism that such teachers have adopted for dealing with such controversy. Thus, we surveyed 56 religious teachers using a Likert‐type questionnaire developed for this research, as well as interviewed 11 teachers to more deeply probe their approaches. In addition, we surveyed 15 religious scientists, so that we could both contrast their views with our teacher samples as well as to better understand their coping strategies when confronted by scientific topics that challenge their beliefs. Results indicated that no single philosophical approach earned overwhelming support from the teachers or scientists. Instead, most of the subjects relate separately to each source of possible conflict in accordance with the philosophical approach that appears to be the most fruitful for resolving such conflicts. Moreover, both the scientists and the teachers felt less conflicted toward the specific subject of geological time, in comparison to issues connected to creation of the earth and (especially) evolution. The teachers did differ from the scientists in their preference toward philosophical approaches which help them better integrate the domains of science and religion. Based on our findings, we are able to suggest a set of strategies to help teachers overcome their difficulties in teaching ‘controversial’ science topics to a religiously oriented student population.  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

Drawing from the phenomenographic perspective, this study investigated Chinese science teacher educators’ conceptions of teaching nature of science (NOS) to preservice science teachers through two semi-structured interviews. The subjects were twenty-four science teacher educators in the developed regions in China. Five key dimensions emerged from the data on the conceptions of teaching NOS, including value of teaching NOS, NOS content to be taught, incorporation of NOS instruction in courses, learning of NOS, and role of the teacher. While some of these dimensions share much similarity with those reported in the studies of conceptions of teaching in general, some are distinctively different, which is embedded in some unique features of teaching NOS to preservice science teachers. These key dimensions can constitute the valuable components of the module or course to train science teachers or teacher educators to teach NOS, provide a framework to interpret the practice of teaching NOS, as well as lay a foundation for probing the conceptions of teaching NOS of other groups of subjects (e.g., school teachers’ conceptions of teaching NOS) or in other contexts (e.g., teaching NOS to in-service teacher).  相似文献

In case studies of two first-year elementary classroom teachers, we explored the influence of informal science education (ISE) they experienced in their teacher education program. Our theoretical lens was identity development, delimited to classroom science teaching. We used complementary data collection methods and analysis, including interviews, electronic communications, and drawing prompts. We found that our two participants referenced as important the ISE experiences in their development of classroom science identities that included resilience, excitement and engagement in science teaching and learning–qualities that are emphasized in ISE contexts. The data support our conclusion that the ISE experiences proved especially memorable to teacher education interns during the implementation of the No Child Left Behind policy which concentrated on school-tested subjects other than science.  相似文献

In this paper, the development of sixth grade students’ critical thinking skills in science courses is discussed relatively to the contribution of the integration of aspects of History of Science into instruction. Towards this direction a project on electromagnetism was designed and implemented aiming to engage primary school students in a critical examination of knowledge (importance, complexity and human implications) by generating argumentation and discussion in their classrooms. The “Test of Everyday Reasoning (TER)”, which targets the core critical thinking skills identified in “The Delphi Report” consensus, was translated and standardized for the Greek population in order to be used for the project’s assessment. A pre-post analysis was conducted for the experimental group and the control group. The encouraging results regarding critical thinking skills development are supportive to the integration of aspects of History of Science in science courses.  相似文献

In this short paper, the author looks back over the past few years at the experience gained in English schools of mixed‐ability teaching in science, and makes some personal interpretation of the lessons to be learned from that experience. It is hoped that some of these issues will be of relevance to other countries too.  相似文献

This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher–students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants’ instruction with computer technology was (Teacher) initiation–(Student and Teacher) response sequences–(Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers’ learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers’ own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.  相似文献

A characterization of the modelling process in science is proposed for science education, based on Mario Bunge’s ideas about the construction of models in science. Galileo’s Dialogues are analysed as a potentially fruitful starting point to implement strategies aimed at modelling in the classroom in the light of that proposal. It is argued that a modelling process for science education can be conceived as the evolution from phenomenological approaches towards more representational ones, emphasizing the role of abstraction and idealization in model construction. The shift of reference of theories—from sensible objects to conceptual objects—and the black-box models construction process, which are both explicitly presented features in Galileo’s Dialogues, are indicated as highly relevant aspects for modelling in science education.  相似文献

This paper presents the results of a case study involving 282 Taiwanese elementary science teachers at the elementary level. These teachers provided responses to the science efficacy instrument (STEBI-A) and also provided personal data regarding how their years of general (YTE) and science (YTS) teaching experience may have influenced student achievement in science. Researchers used two multivariate analysis of variance (MANOVA) to investigate the interaction and influence of YTE and YTS upon the personal science teaching efficacy (PSTE) and science teaching outcome expectations (STOE) of these teachers. The results advocate the position that the years of general teaching experience of elementary science teachers in Taiwan have a significantly greater impact upon their personal science teaching efficacy and science teaching outcome expectations than years of teaching science. This evidence calls into question whether Bandura and Tschannen-Moran’s view of teacher efficacy as both context and subject matter specific at the elementary level can be applied to Taiwan elementary teachers who teach science. The results of this study should benefit educators and policy-makers with respect to future elementary teacher education throughout Taiwan and other developing nations.

This paper describes procedures by which two types of measures of Pedagogical Content Knowledge (PCK) were developed and validated: (a) PCK Survey and (b) PCK Rubric. Given the topic-specificity of PCK, the measures centered on photosynthesis as taught in high school classrooms. The measures were conceptually grounded in the pentagon model of PCK and designed to measure indispensable PCK that can be applied to any teacher, in any teaching context, for the given topic. Because of the exploratory nature of the study, the measures focus on two key components of PCK: (a) knowledge of students’ understanding in science and (b) knowledge of instructional strategies and representations. Both measures have established acceptable levels of reliability as determined by internal consistency and inter-rater agreement. Evidence related to content validity was gathered through expert consultations, while evidence related to construct validity was collected through analysis of think-aloud interviews and factor analyses. Issues and challenges emerging from the course of the measure development, administration, and validation are discussed with strategies for confronting them. Directions for future research are proposed in three areas: (a) relationships between PCK and teaching experiences, (b) differences in PCK between science teachers and scientists, and (c) relationships between PCK and student learning.  相似文献

This paper discusses the findings of an evaluative and interpretive study into the potential of in‐service education to improve science education in Swaziland. Short‐term and long‐term effects of an in‐service intervention are evaluated in terms of changes in classroom processes. The teaching approach of participating teachers has been monitored and analysed before, during and 1 year after the in‐service intervention, to assess whether changes occurred. The study revealed the subjective interpretations of teachers about those changes, also in relation to contextual factors. Recommendations are put forward to enhance the potential of in‐service education in comparable contexts.  相似文献

The aim of this research is to ascertain teachers’ opinions on what elements of nature of science (NOS) and science–technology–society relationships (STS) should be taught in school science. To this end an adapted version of the questionnaire developed by Osborne et al. is used. Our results show that experts consulted by Osborne et al. and Spanish teachers confer similar importance on the provisional, experimental, and predictive nature of scientific knowledge based on some of the procedures used such as the drawing up of hypotheses and the analysis and interpretation of data. We also look into the relationship between the teachers’ views and their educational background. 1 1. In this article, Educational Background means the scientific training gained by teachers at university. Results suggest that philosophy teachers are more concerned with the inclusion of NOS and STS topics in science curricula than science teachers, although further studies will be necessary. Some suggestions concerning the university training of science teachers are also discussed.  相似文献
