The twenty‐first century is characterized by multiple, frequent and remarkable scientific advancements, which have a major effect on the decisions that govern everyday life. It is therefore vital to give proper comprehensive scientific education to the population and provide it with the right tools for decision‐making. This in turn requires that we foster a positive attitude among students towards science studies and encourage them to choose sciences as their major subjects. The following study examines 10th‐grade high school students in an attempt to understand and document the influential factors underlying their attitudes towards science studies. The study is conducted through a qualitative research methodology, gathering data based on interviews. This methodology exposes the students’ feelings, views and beliefs, and explores the characteristics of the factors influencing students’ attitudes. Of these factors, we found the most significant for high school students to be interpersonal interaction between teacher and student, the relevance and authenticity of the topics being studied, and the diversity of the teaching methods. We therefore suggest that these three elements should be given particular emphasis by teachers and teacher educators.  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

Due to the implementation of a 9‐year integrated curriculum scheme in Taiwan, research on team teaching and web‐based technology appears to be urgent. The purpose of this study was incorporated web‐assisted learning with team teaching in seventh‐grade science classes. The specific research question concerned student performance and attitudes about the teaching method. Two certified science teachers and four classes of the seventh graders participated in this study. It used a mixed methods design, incorporating both quantitative and qualitative techniques. The main data included students’ scores, questionnaires, teachers’ self‐reflections, and the researcher’s interviews with teachers. The results showed that the average final examination scores of students experiencing the experimental teaching method were higher than that of those receiving traditional teaching. The two teaching methods showed significant difference in respect of students’ achievement. The research had limitations because of students’ abilities of data collection, computer use, and discussion, but more than one‐half of the students preferred the experimental method to traditional teaching. However, team teachers would encounter the problems of technology ability, time constraints, and entrance examination pressure.  相似文献

In the US, there may be few scientific concepts that students maintain preconceived ideas about as strongly and passionately as they do with regard to evolution. At the confluence of a multitude of social, religious, political, and scientific factors lies the biology teacher. This phenomenological study provides insight into the salient aspects of teaching evolution as viewed by public high school biology teachers. Transcribed interviews were coded, and data were sorted resulting in key themes regarding teachers’ views of evolution education. These themes are presented against the backdrop of extant literature on the teaching and learning of evolution. Suggestions for science teacher educators are presented such that we can modify teacher preparation programs to better prepare science teachers to meet the challenges of teaching evolution.  相似文献

The purpose of this study was to explore elementary students’ listening comprehension changes using a Web-based teaching system that can diagnose and remediate students’ science listening comprehension problems during scientific inquiry. The 3-component system consisted of a 9-item science listening comprehension test, a 37-item diagnostic test, and 107 scaffoldings of listening strategies. The diagnostic and remediation system was trialed with grade 6 students (N?= 526) from southern Taiwan who were selected by cluster sampling. The participants were asked to take the 3 components individually on a computer. The students’ responses were collected and analyzed to document performance and changes. Results indicated that the diagnostic test had a positive influence on science listening comprehension proficiency and addressed potential problems, while the scaffolding helped remediate confirmed listening difficulties. Instructional implications for classroom diagnosis–remediation applications are discussed and future research is outlined.  相似文献

Recent accounts by cognitive scientists of factors affecting cognition imply the need to reconsider current dominant conceptual theories about science learning. These new accounts emphasize the role of context, embodied practices, and narrative‐based representation rather than learners’ cognitive constructs. In this paper we analyse data from a longitudinal study of primary school children’s learning to outline a framework based on these contemporary accounts and to delineate key points of difference from conceptual change perspectives. The findings suggest this framework provides strong theoretical and practical insights into how children learn and the key role of representational negotiation in this learning. We argue that the nature and process of conceptual change can be re‐interpreted in terms of the development of students’ representational resources.  相似文献

The need for the inclusion of socio‐scientific issues (SSI) into science curricula has been generally accepted, but relatively few science teachers have incorporated SSI into their courses. Most science teachers feel that their most important task by far is to teach the principles of science, and any substantive pedagogical changes represent a burden. Reformers and researchers often point out science teachers' lukewarm reactions to the reforms as a major barrier for educational changes but pay little attention to teachers' deeper values and inspirations. However, there are some teachers who address SSI out of their own personal initiative. Detailed case studies of four such teachers showed that although the teachers were aware of Science, Technology, Society or other reform efforts, they developed their own thrust and materials for SSI based on their own values, ideals, philosophies and personal concerns. This suggests that the current curriculum reforms (Science, Technology, Society, SSI, and Nature of Science) tend to suggest theoretical ideals, but do not effectively connect with teachers' deeper values and ideals.  相似文献

English

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

Mathematics teaching and subject‐matter acquisition of two groups of linguistic minority students were studied; one in a minolingual second‐language class and the other in a traditional bilingual‐education model in the city of Oslo, Norway. The background of attempts at bilingual education in the Norwegian context is presented, and some aspects of bilingual education, bilingual pedagogy and research‐based perspectives on the role of bilingual education in subject‐matter acquisition is discussed. On the basis of an empirical study of the teaching situation of linguistic‐minority students it is concluded that linguistic‐minority students profit from bilingual mathematics teaching. The empirical research results indicate that linguistic‐minority students (LMSs) with a bilingual‐education (BE) background can achieve as good or better results in mathematics as monolingual students. The strength of bilingual education can therefore be said to reside in the favourable conditions that it creates for the comprehension of linguistic‐minority students of the content taught. By creating favourable conditions bilingual subject‐matter teaching also fulfils minorities’ expectations of participating in content‐area instruction: to understand what is being communicated in subject‐matter teaching and to learn what is normally expected to be learned in subject‐matter teaching. It is therefore legitimate to argue for bilingual education on pedagogical grounds without the support of old‐fashioned anthropological or psychological arguments.  相似文献

The present study deals with a school‐based professional development trajectory for secondary science teachers, aiming at scaffolding teachers in open‐inquiry teaching for the topic of water quality. Its design was based on the leading principle of ‘guiding by scaffolding’. Seven experienced teachers participated in institutional meetings and teaching at school. The research focused on designing scaffolding tools, addressing these tools in the meetings, and implementing them in the classroom. The main research data were obtained from meetings, classroom discussions, and observations. The results indicated that the professional development trajectory has promoted teachers’ learning of scaffolding students in open inquiry, especially the ability to know when and how to give students a well‐balanced combination of ‘structure’ for open‐inquiry learning and sufficient ‘space’ for that. The implications for science teacher 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

Fourth‐grade students’ knowledge of observable moon phases and patterns of change, as well as conceptual understanding of the cause of moon phases, was investigated before and after special instruction. Pretest and post‐test data for 48 students were used to address the research question related to observable moon phases and patterns of change. Interviews were conducted with 10 students on a post‐only basis to provide data on understanding the cause of moon phases. The researchers used the constant comparative method to analyse data. Pretest results indicate these students had not met the expectations expressed in the U.S. Science Education Standards for lunar concepts. Post‐test results reveal a very positive performance on observable moon phases and patterns of change, as well as the cause of moon phases. Interpretation and implications of these findings are provided.  相似文献

This study examined how instructional challenges presented by gifted students shaped teachers’ instructional strategies. This study is a qualitative research grounded in a social constructivist framework. The participants were three high school science teachers who were teaching identified gifted students in both heterogeneously- and homogeneously-grouped classrooms. Major data sources are classroom observations and interviews. Data analysis indicated that these science teachers developed content-specific teaching strategies based on their understanding of gifted students, including: (a) instructional differentiation, e.g., thematic units, (b) variety in instructional mode and/or students’ products, (c) student grouping strategies and peer tutoring, (d) individualized support, (e) strategies to manage challenging questions, (f) strategies to deal with the perfectionism, and (g) psychologically safe classroom environments.  相似文献

The purpose of this study is to promote more open-ended inquiry activities in junior high school science lessons in the current educational system with fixed textbooks. Researchers adapted existing curriculum-based experimental activities for more open-ended inquiry ones. In addition, the whole class was provided with more opportunities to explore complete activities in limited teaching time. This study used Hazel's proposals of levels of inquiry. The method was to carry out the current 8th grade experiments through the step-by-step teaching material modification (from levels of inquiry 0 to 2b) and to combine the experimental teaching method with the 5E (engage, explore, explain, elaborate, and evaluate) learning cycle. After a quasi-experimental study, we compared the traditional teaching method with the step-by-step open-ended inquiry teaching one on 8th graders' basic and integrated science process skills and academic achievements. The study result showed that the academic achievement in the experimental group, based on the same instructional time, was not worse than that in the control group. No significant difference was found on the total scores of the basic science process skills between the two groups, but a significant difference was found on the "predicting" dimension. There was a significant difference on the total scores of the integrated science process skills between the two groups. Significant differences were found on "interpreting data" as well as "experiment designing" dimensions. Hence, the study indicated that it could enhance students' inquiry ability through step-by-step openly inquiry levels to change the existing curricula, which served as a reference of educational reform.  相似文献

Developing scientifically literate students who understand the socially contextualized nature of science and technology is a national focus of science education reform. Science educators’ perceptions of risks and benefits of new technologies (such as biotechnology) may shape their instructional approaches. This study examined the perceived risk of biotechnology of four groups of science educators: pre-service science teachers, in-service science teachers, biology graduate teaching assistants, and biology professors (n = 91). Data sources included a survey instrument and card sort task designed to determine the respondents’ structure of risk perception and factors contributing to this structure. The perceptions of the four educator groups were compared and contrasted along these dimensions. Results showed that the teacher groups were similar along many aspects of risk perception, but university professors were more likely to view the more subtle “gray areas” between biotechnology risks. The results are discussed in the context of understanding teacher risk perception on science pedagogical practice as well as the role of content knowledge and teaching experience on risk perception formation.  相似文献

This study explores five minority preservice teachers’ conceptions of teaching science and identifies the sources of their strategies for helping students learn science. Perspectives from the literature on conceptions of teaching science and on the role constructs used to describe and distinguish minority preservice teachers from their mainstream White peers served as the framework to identify minority preservice teachers’ instructional ideas, meanings, and actions for teaching science. Data included drawings, narratives, observations and self-review reports of microteaching, and interviews. A thematic analysis of data revealed that the minority preservice teachers’ conceptions of teaching science were a specific set of beliefs-driven instructional ideas about how science content is linked to home experiences, students’ ideas, hands-on activities, about how science teaching must include group work and not be based solely on textbooks, and about how learning science involves the concept of all students can learn science, and acknowledging and respecting students’ ideas about science. Implications for teacher educators include the need to establish supportive environments within methods courses for minority preservice teachers to express their K-12 experiences and acknowledge and examine how these experiences shape their conceptions of teaching science, and to recognize that minority preservice teachers’ conceptions of teaching science reveal the multiple ways through which they see and envision science instruction.  相似文献
