This study explores how activities developed by science experts in partnership with middle school teachers were employed and interpreted. The goals of this partnership were to (a) help the science teacher meet earth science content standards in new ways, (b) expose students to ‘real world’ experiences outside their school setting, and (c) positively impact teacher practice by providing a program to be used as a catalyst for future learning. Over 300 sixth graders mostly underrepresented science students attended activities at an aquarium serving an urban West Coast urban context. Science teachers, non-science teachers, scientists, and volunteers were all engaged in pre-trip instruction, professional development opportunities, and follow-up activities as this partnership effort explored ways to enhance local literacy initiatives across the curriculum. Results suggest that teacher beliefs about informal education impacted their view and participation in the program and the level of submersion of teachers in collaboration strongly affects the ability to serve underrepresented students on informal excursions. Implications for teacher education and outreach are discussed.  相似文献

This study was conducted in a reform-based mathematics and science teacher education program in the USA, the Maryland Collaborative for Teacher Preparation(MCTP). The goal of the undergraduate program was to prepare upper elementary/middle level specialists in mathematics and science. One significant aspect of the MCTP was the expectation that the program's professors (in mathematics and science) would model a new vision of effective pedagogy based on reform-based recommendations. We determined, in general, that the program's mathematics and science content professors accepted the dual role of modeling effective instruction at the same time they were delivering content. However, this dual responsibility raised in their minds an ‘issue of appropriate balance’ between content and pedagogical foci in their courses. Previously, the professors' had not questioned a focus heavily tilted toward content coverage. We also determined that the program's teacher candidates believed that the mathematics and science professors modeled effective instruction. One of the primary reasons that the teacher candidates believed that their professors were modeling effective instruction was that the focus in the courses was primarily on conceptual understanding, not memorization. A major implication was that the professors' modeling of reform-based instruction prompted the teacher candidates to develop a new vision of mathematics and science teaching shaped by their professors' example.  相似文献

This paper focuses on a model of teacher change based on a study of a science discipline-based professional education program and on an understanding of teacher change in terms of an agency| structure dialectic. Professional education programs should expand teachers' capacity to act in a range of fields. Conducted over one year, this study used socio-cultural theory to examine the role of cultural schema and resources in the enactment of new pedagogical structures by two teachers who demonstrated widely variable responses to their experience of a professional chemistry education program. Hermeneutic and phenomenological methods of study supported the examination of teacher actions and narratives as sources of data. The analyses of these data sources resulted in greater understanding of the relationship between schema, resources and structure and the relationship between structure and teacher agency. Structures are dynamic and if a teacher uses a resource such as an inquiry-based instruction protocol without the attendant cultural schema such as the value of questioning then the structure that is implemented will be different from that the teacher experienced in the professional education program. This understanding supported an explanation of teacher change in terms of teacher agency that constituted our learning from the study and resulted in changes to aspects of the professional education program.  相似文献

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2 classrooms in rural school districts. The research specifically examined changes in (a) teachers’ content knowledge in science; (b) teachers’ self-efficacy related to teaching science; (c) classroom instructional time allotted to science; and (d) instructional strategies used in science. The study also investigated contextual factors contributing to or hindering changes in science instruction. Data sources included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and classroom observations. After one year in the program, teachers showed increased content knowledge and self-efficacy in teaching science; they spent more instructional time on science and began using different instructional strategies. Key contextual factors included curricular demands, resources, administrative support, and support from other teachers.  相似文献

The research reported in this study examines the very first time the participants planned for and enacted science instruction within a “best-case scenario” teacher preparation program. Evidence from this study indicates that, within this context, preservice teachers are capable of implementing several of the discursive practices of science called for in standards documents including engaging students in science investigations and constructing evidence-based explanations. The participants designed experiences that allowed their students to interact with natural phenomena, gather evidence, and craft explanations of natural phenomenon. The study contends that the participants were able to achieve such successes due to their participation in a teacher education program and field placement, which were designed using a comprehensive, conceptual framework. Video of the participant’s teaching and annotated self-analysis videos served as the primary data for this study. Implications for future research and elementary science teacher education are discussed.  相似文献

Given the high attrition rate of beginning science teachers, it is imperative to better prepare science preservice teachers, so that they can be successful during the early years of their teaching. The purpose of this study was to explore science preservice teachers’ views of themselves as a future teacher, in particular their hopes and fears for science teaching and the experiences that help to shape their possible selves. Employed were qualitative methods, which included open-ended surveys and face-to-face interviews. Eleven preservice teachers who enrolled in a secondary science teacher preparation program participated. Findings showed six categories of future selves with the most frequent category being for effective/ineffective science teaching. When their hoped-for and feared selves were not balanced, participants articulated more fears. Regarding the primary influence in shaping their hopes and fears, diverse past experiences related to teaching and learning appeared to be more salient factors than science teacher education program. Given the enriched understanding of the science preservice teachers’ perceptions, we provided suggestions for science teacher educators.  相似文献

This paper reports part of a larger study which was designed to investigate current practices in initial teacher education programs in Australia. The main data collection was by telephone interviews, which were carried out with science education specialists and program coordinators at all institutions which offer primary teacher education or secondary science teacher education. The interviews focused on practices in relation to program structures, science content studies, science methods studies and links to science-related school projects or to science business/industry. A large number of innovative practices were described. In addition, several case studies were carried out, which focused on particular innovations. The study identified several aspects of science teacher education which were of concern.  相似文献

The study reported here investigated experienced teachers’ views on several nature of science (NOS) issues 2 to 5 years after they completed a demanding secondary science teacher education program in which the NOS was an extensive and recurring component. Both quantitative and qualitative data were collected and analyzed to determine study participants’ NOS understanding. Study participant’s NOS views were determined to be generally accurate and robust, suggesting that experiences in their science teacher education program had a long-lasting positive impact on NOS understanding. The preservice program that study participants completed has several unique features that may account for that long-lasting impact and has implications for preservice and inservice science teacher education professional development.

Teachers’ acquisition of knowledge about English word structure   总被引：1，自引：0，他引：1  
Previous research suggests that teachers’ knowledge about English word structure (e.g., the phonological structure of words and common orthographic patterns in English) may be limited, although this knowledge is important for effective teaching of word decoding. This study examined teacher education students’ knowledge about word structure, and improvements in their knowledge as a result of instruction, using three tasks: graphophonemic segmentation, classification of pseudowords by syllable type, and classification of real words as phonetically regular or irregular. Participants came from a special education certification program and included both preservice and inservice teachers. Results indicated that prior preparation to teach reading influenced participants’ initial performance on two of the three word-structure tasks (all but graphophonemic segmentation); however, prior experience in teaching reading did not influence word-structure knowledge. A subset of participants who received specific instruction about word structure improved their knowledge relative to a comparison group of teacher education students who did not receive word-structure instruction. Prior preparation did not influence participants’ responsiveness to instruction. Conclusions support the viewpoint that teacher education must include information about English word structure for educators who will teach reading and suggest that sufficiently intensive instruction may be important in developing word-structure knowledge.  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 reports the participation of 13 secondary science teachers in informal support networks and how that participation was associated with their nature of science (NOS) teaching practices 2 to 5 years after having graduated from the same science teacher education program. The nine teachers who participated in informal support networks taught the NOS at high/medium levels, while the four non-participating teachers taught the NOS at low levels. The nine high/medium NOS implementation teachers credited the informal support networks for maintaining/heightening their sense of responsibility for teaching NOS and for helping them navigate institutional constraints that impede effective NOS instruction. Several high/medium NOS instruction implementers initially struggled to autonomously frame and resolve the complexities experienced in schools and thus drew from the support networks to engage in more sophisticated forms of teacher decision-making. In contrast, the NOS pedagogical decisions of the four teachers not participating in support networks were governed primarily by the expectations and constraints experienced in their schools. Implications of this study include the need for reconsidering the structure of teacher mentorship programs to ensure they do not promote archaic science teaching practices that are at odds with reform efforts in science education.

Every aspect of teaching, including the instructional method, the course content, and the types of assessments, is influenced by teachers’ attitudes and beliefs. Teacher education programs play an important role in the development of beliefs regarding teaching and learning. The purpose of the study was to document pre-service teachers’ views on science, scientists, and science teaching as well as the relations between these views and the offered courses over several years spent in an elementary science teacher training program. The sample consisted of 145 pre-service elementary science teachers who were being trained to teach general science to students in the 6th through 8th grades. The research design was a cross-sectional study. Three different instruments were used to collect the data, namely, the “Draw a Scientist Test”, “Draw a Science Teacher Test”, and “Students’ Views about Science” tests. The elementary science teacher training program influenced pre-service science teachers’ views about science, scientists and science teaching to different degrees. The most pronounced impact of the program was on views about science teaching. Participants’ impressions of science teaching changed from teacher-centered views to student-centered ones. In contrast, participants’ views about scientists and science did not change much. This result could be interpreted as indicating that science teacher training programs do not change views about science and scientists but do change beliefs regarding teaching science.  相似文献

We investigated curricular and pedagogical innovations in an undergraduate science methods course for elementary education majors at the University of Maryland. The goals of the innovative elementary science methods course included: improving students’ attitudes toward and views of science and science teaching, to model innovative science teaching methods and to encourage students to continue in teacher education. We redesigned the elementary science methods course to include aspects of informal science education. The informal science education course features included informal science educator guest speakers, a live animal demonstration and a virtual field trip. We compared data from a treatment course (n = 72) and a comparison course (n = 26). Data collection included: researchers’ observations, instructors’ reflections, and teacher candidates’ feedback. Teacher candidate feedback involved interviews and results on a reliable and valid Attitudes and Beliefs about the Nature of and the Teaching of Science instrument. We used complementary methods to analyze the data collected. A key finding of the study was that while benefits were found in both types of courses, the difference in results underscores the need of identifying the primary purpose for innovation as a vital component of consideration.  相似文献

Technology is not in the forefront of teacher education program thinking and planning. Yet, it is the tool dramatically changing education. Internationally, the role of technology has evolved from the role of assisting the teacher in personal management to using technology for instruction. To respond to this need, universities are altering courses to infuse the introduction and utilization of technological tools to enhance instruction. The end product is that pre-service teachers should graduate with the skills to seamlessly integrate technology to advance student learning. This study looks at a large comprehensive university’s available data on pre-service teachers regarding their utilization of technology. The focus of the study was to (a) document the technology skills within the university's capstone project, (b) examine the capstone project data to confirm or refute the premise that pre-service teachers integrate technology, and (c) review other internal data to assess pre-service teacher competencies on technology.  相似文献

It is problematic whether primary teachers benefit by completing a first degree especially when the teaching of specific subjects, here science, is the focus of attention. This study reports the comparative results of interviewing thirteen Canadian and ten Australian student teachers, both about to commence their Bachelor of Education. The Canadian students had completed an initial degree while nine of the Australian students were school leavers. The interviews, which explored views about teaching primary science, were analysed with this factor in mind. Student teacher perceptions reported include: how to recognise a “good” primary science teacher; perceptions of self as a “good” primary science teacher; expectations of how the teacher education program could assist their science teaching; and whether (for the Canadian students) the initial degree will help in becoming a primary science teacher. Analysis of the interviews suggests possible influences a first degree (among other factors) may have on perceptions related to primary science teaching and raises questions about what is the best general approach for preparing primary teachers to teach science effectivly.  相似文献

ABSTRACT

The purpose of this qualitative study was to investigate the contributions of pre-service teachers’ memories of science and science education, combined with their experiences in a STEM-focused teacher preparation programme, to their developing identities as elementary school teachers of science. Data collected over three years include a series of interviews and observations of science teaching during elementary teacher preparation and the first year of teaching. Grounded within a theoretical framework of identity and using a case-study research design, we examined experiences that contributed to the participants’ identity development, focusing on key themes from teacher interviews: memories of science and science instruction, STEM-focused teacher preparation programme, field experiences, first year of teaching, and views of effective science instruction. Findings indicate the importance of exposure to reform strategies during teacher preparation and are summarised in main assertions and discussed along with implications for teacher preparation and research.  相似文献

Between the 1980s and 2007, Portugal used to have one-stage (5-year period) initial teacher education (ITE) programs. In 2007 and consistent with the Bologna process guidelines, Portuguese teacher education moved toward a two-stage model, which includes a 3-year undergraduate program of subject matter that leads to a licenciatura (or bachelor) degree and a 3-year professional master in the teaching of a subject. The way that teacher educators perceive the ITE programs effects the education of prospective teachers and consequently the future of science education. This paper aims at analyzing how science teacher educators perceived the changes that took place in this formal way of educating junior school (7th–9th grades) and high school (10th–12th grades) science teachers in Portugal, due to the implementation of the Bologna guidelines. To attain the objectives of the study, 33 science teacher educators including science specialists and science education specialists answered an open-ended online questionnaire, which focused on the strengths and weaknesses of the pre- and post-Bologna ITE programs, the overall quality of teacher education and measures for improving ITE. The results indicate that science teacher educators were quite happy with all of the ITE models, but they expressed the belief that both the science and the teaching practice components should be strengthened in the post-Bologna masters in teaching. Meanwhile, changes were introduced in Portuguese educational laws, and they proved to be consistent with the opinions of the participants. However, the professional development of teacher educators along with evidence-based ITE programs seems to be necessary conditions for overcoming the challenges that teacher education is still facing in Portugal and worldwide.  相似文献

Science teachers from secondary schools in Tanzania were offered an in-service arrangement to prepare them for the integration of technology in a student-centered approach to science teaching. The in-service arrangement consisted of workshops in which educative curriculum materials were used to prepare teachers for student-centered education and for the use and application of Microcomputer Based Laboratories (MBL)—a specific technology application for facilitating experiments in science education. Quantitative and qualitative data were collected to study whether the in-service arrangement impacted teacher learning. Teacher learning was determined by three indicators: (1) the ability to conduct MBL-supported student centered science lessons, (2) teachers’ reflection on those lessons and (3) students’ perceptions of the classroom environment. The results of the research indicate that the teachers’ were able to integrate MBL in their science lessons at an acceptable level and that they were able to create a classroom environment which was appreciated by their students as more investigative and open-ended.  相似文献

This investigation explores the effectiveness of a teacher preparation program aligned with situated learning theory on preservice science teachers' use of technology during their student teaching experiences. Participants included 26 preservice science teachers enrolled in a 2‐year Master of Teaching program. A specific program goal was to prepare teachers to use technology to support reform‐based science instruction. To this end, the program integrated technology instruction across five courses and situated this instruction within the context of learning and teaching science. A variety of data sources were used to characterize the participants' intentions and instructional practices, including classroom observations, lesson plans, interviews, and written reflections. Data analysis followed a constant comparative process with the goal of describing if, how, and why the participants integrated technology into their instruction and the extent to which they applied, adapted, and innovated upon what they learned in the science teacher preparation program. Results indicate that all participants used technology throughout their student teaching for reform‐based science instruction. Additionally, they used digital images, videos, animations, and simulations to teach process skills, support inquiry instruction, and to enhance student engagement in ways that represented application, adaptation, and innovation upon what they learned in the science teaching methods program. Participants cited several features of the science teacher preparation program that helped them to effectively integrate technology into their instruction. These included participating in science lessons in which technology was modeled in the context of specific instructional approaches, collaborating with peers, and opportunities for feedback and reflection after teaching lessons. The findings of this study suggest that situated learning theory may provide an effective structure for preparing preservice teachers to integrate technology in ways that support reform‐based instruction. © 2013 Wiley Periodicals, Inc.
