Agency at work: two beginning science teachers’ stories in a context of curriculum reform in China

In this study, a sociocultural perspective was adopted to understand the interplay between identity and agency in a context of science education reform in China. The manifestation of agency and the interaction between identity and agency were examined with two beginning science teachers teaching with practical work in high school. As part of this study, the identity formation of beginning science teachers was conceived as a site for locating and investigating teacher agency. Based on multiple data sources, we identified six spaces in which the two participants’ agency manifested: (1) personal characteristics; (2) personal beliefs; (3) interactions with students; (4) interactions with colleagues; (5) curriculum materials; and (6) high-stakes examinations. In each space, the two participants’ agency contrasted in terms of perspectives and actions: one was passive, less confident and negative, whereas the other active, more confident and positive. Moreover, it was found that their contrary actions were the result of different perspectives. Based on the findings, a model of the interplay between the identity and agency of an individual science teacher is proposed in a context of curriculum reform. The implications of this model for future research and science teacher development are discussed.     

School Innovation in Science: A Model for Supporting School and Teacher Development

‘School Innovation in Science’ represents a model, developed through working with more than 200 Victorian schools, to improve science teaching and learning. SIS works at the level of the science team and the teacher, providing resources to challenge and support the change process. Its emphasis is on strategic planning supported by a framework for describing effective teaching, materials for auditing practice and planning initiatives, and a networked support structure. Experience and results from the project, concerning the nature and extent of change, will be used to provide insight into the multidimensional nature of the change process and to suggest a number of principles concerning support for change. Arising out of this, the major elements of a School Innovation Model are identified, that supports a transformative agenda for schools more generally.     

理科教师的科学本质观对科学教育的影响

人们对科学本质的认识经历了由科学的“真理观”向科学的“建构观”的转变。不同的科学本质观将直接影响着教师对科学教育目标的不同理解,对科学知识的不同选择,对教学主题的不同设计、教学话语的不同使用,对学生学习的不同评价。教师不同的科学本质观及其教学行为影响着学生的科学本质观的形成,影响着学生对科学内容的理解以及看待问题的思维方式。     

Learning What It Takes to Teach Science: High School Students as Science Teachers for Middle School Students

This study examines the influence of St. John's University Summer Science Experience and Teacher Mentoring Program on African American and Hispanic high school students' interest in science and science teaching as career goals. In the first phase of the program, high school students from six school districts in Suffolk County, Long Island (a suburb of metropolitan New York City) engaged in investigative science experiences that emphasized environmental science, chemistry, and technology and learned about effective science pedagogy. The second phase of the program functioned as a teaching practicum for the high school students, where they planned for instruction and taught middle school students investigations similar to those that they had engaged in during the summer program. Various surveys were developed to assess high school students' attitudes about science and science teaching, knowledge of effective teaching approaches, knowledge of ways to motivate younger students, and the overall impact of the program on the high students' interest in science and/or science teaching as career goals. Program evaluations reveal that over 75% of the students expressed an interest in considering science or science teaching as career possibilities. Implications for minority teacher recruitment are discussed.     

A study of practical‐moral knowledge in science teaching: Case studies in physical science classrooms

This study further extends a conceptual framework that explores science teaching as a “practice” not reducible to the application of formal knowledge, but as informed by teachers' practical‐moral knowledge. A hermeneutic model was developed to examine practical‐moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions between them. The study also aimed to analyze teachers' actions in terms of their interpretations and commitments as they realize “internal goods” of their practice. Ethnographic case studies of three science teachers were conducted through classroom observation, in‐depth interviews and dialogues, and artifact analysis. A commitment of preparing students for national exams was common to the three teachers but was manifested differently in classroom practices. This commitment originated from interpretations about the duty of “good” teachers not letting students and schools down. Other emergent commitments were commitments: to conceptual understandings, to “challenge” learners, and to social modeling. We present each with associated interpretations and actions. The concepts of practical wisdom (phronesis) and gap closing are used to characterize teachers' practical knowledge and its development respectively. Implications for teacher education are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 929–951, 2010     

Computer,craft, complexity,change: explorations into science teacher knowledge

In this article we review the notion of teacher knowledge from four metaphorical standpoints – teacher knowledge as computer, as craft, as complexity and as change. We employ each of these metaphors to examine and analyse the work of one teacher of science. We draw implications from our analysis for teacher education, teacher development and the study of teaching.

Learning from students,inquiry into practice,and participation in professional communities: Beginning teachers' uneven progress toward equitable science teaching

In this research project, we investigated two beginning secondary science teachers' efforts to learn to teach science in ways that build from and celebrate the ethnic, gender, linguistic, and academic diversity of their students. To do so, we followed Troy and Brian from their preservice teacher education experiences through their first year of teaching 8th grade physical science at local junior high schools. We also conducted a follow‐up observation and interview with each participant after he had moved past the beginning stage of survival in the teaching profession—once in his fourth year of public school science teaching. Through qualitative analysis of interviews, classroom observations, and teachers' written work, we identified patterns and explored commonalities and differences in Troy and Brian's views and practices tied to equity over time. In particular, we examined successes and challenges they encountered in learning to teach science for all (a) from their students, (b) from inquiry into practice, and (c) from participation in professional communities. In our implications, we suggest ways teacher educators and induction professionals can better support beginning teachers in learning to teach science to all students. In particular, we highlight the central roles both individual colleagues and collective school cultures play in aiding or impeding beginning teachers' efforts to learn from students, from practice, and from professional communities. © 2006 Wiley Periodicals, Inc.

Sources of Self-efficacy in a Science Methods Course for Primary Teacher Education Students

Self-efficacy has been shown to be an issue of concern for primary teacher education students – many of them have low self-efficacy and this can negatively affect their future teaching of science. Previous research has identified four factors that may contribute towards self-efficacy: enactive mastery experiences, vicarious experiences, verbal persuasion and physiological/affective states. It could also be argued that there are additional sources of self-efficacy that apply to primary teacher education students, namely cognitive content mastery, cognitive pedagogical mastery and simulated modelling. The main purpose of the present paper was to investigate the relative importance of the various sources of self-efficacy in a primary science methods course. Data on changes in self-efficacy and sources of self-efficacy were collected throughout the course using formal and informal surveys. It was found that the main source of self-efficacy was cognitive pedagogical mastery.     

Museum Experience — a Resource for Science Teacher Education

In this study, the researcher included an extensive science museum experience for the pre-service secondary science teachers within a teaching methods course to enhance their learning to teach science. The extensive museum experience covered four aspects: the visit, discussion with museum educators, the development of lesson plans, and practising teaching in the science museum. Twenty-one pre-service science teachers attended this course. Qualitative methods were used for data collection and analysis. The data sources included field notes, reports, diaries, and interviews. The findings show that this course connecting museum resources and context had created a novel situation for pre-service science teachers to learn how to teach science. The discourses with the museum educators also provided them with innovations in education beyond the gains from traditional teacher education. Through developing and practising teaching activities, they improved their understanding of the meanings and effective ways to use museum resources in science teaching. Pre-service science teachers reported that getting feedback from peers and observing modeling teaching was helpful. This course provided an alternative way to view how scientific activities were developed for junior high students. In general, the use of museum settings provides a new profile of learning and teaching course for pre-service science teachers in Taiwan. Based on the findings, this study makes suggestions for those science teacher educators who would like to use science museum resources and contexts to nurture prospective science teachers.     

Elementary teachers’ science subject matter knowledge across the teacher career cycle

Although widely touted as important, there is little evidence regarding the influence of teaching experience on elementary teachers' science subject matter knowledge (SMK). To better understand this phenomenon, we administered an assessment of science topics taught in the fifth and sixth grades to 169 preservice teachers, 231 fifth-grade teachers, and 208 sixth-grade teachers. We then compared the mean scores of teachers at different stages in the career cycle using one-way and two-way ANOVA and explored the relationship between SMK scores and years of teaching experience using regression analysis. Findings indicate that (i) being assigned to a specific grade level had an impact on teachers' SMK for topics included in the grade level, (ii) teachers' SMK scores were lower later in their careers for both science topics they had never taught and for science topics they were responsible for teaching, and (iii) results differed for fifth and sixth grades. This study adds to the existing literature through the examination of a large sample of elementary teachers, with teachers of varying years of experience, while focusing on the science topics these teachers are responsible for teaching. The results of this study provide strong evidence that (i) years of experience teaching specific science topics is associated with the development of teachers' knowledge of these topics, and (ii) teaching experience, what teachers do in the context of their everyday practice, can be an effective means of self-directed learning for teachers. There is also evidence that this influence is not uniform across years of teaching experience or science topics taught. These findings raise important implications about future research into the mechanism of SMK development through teaching experience and teacher grade-level assignments.     

Transversal traits in science education research relevant for teaching and research: A meta‐interpretative study

This study is a meta‐interpretative analysis that focuses on research conducted and published by other researchers. Concepts central to this study include global practical relevance, curriculum design, and formative situation. We analyzed 35 studies selected from 374 published studies in the years 2000 and 2001 in three journals referenced in the International Scientific Index. Using a replicable methodology developed specifically for this research, we found evidence of s clusters of variables that suggest the existence of transversal traits in the 35 science education research studies. These results form a reference framework of theoretical and practical knowledge relevant for research and practice pertaining to teaching and learning science. © 2008 Wiley Periodicals, Inc.

Expanding computer science education in schools: understanding teacher experiences and challenges

The increased push for teaching computer science (CS) in schools in the United States requires training a large number of new K-12 teachers. The current efforts to increase the number of CS teachers have predominantly focused on training teachers from other content areas. In order to support these beginning CS teachers, we need to better understand their experiences and challenges encountered in the classroom. This study investigated U.S. CS teachers’ perspectives on the demands of teaching computer science and support needed to ensure quality teaching. Results suggested that teachers face a number of challenges, including isolation, lack of adequate computer science background, and limited professional development resources.
