Current trends and missing links in studies on teacher professional development in science education: a review of design features and quality of research

This review provides an overview of the the current state of research on professional development in science education. An analytical frame was used, based on what is known about PD from educational research. Clarke and Hollingsworth’s model for teacher professional growth was also used to categorise the studies according to their aims and outcomes. Exemplar studies in each category are highlighted. In total, 44 recent studies were selected, all referring to science PD. The results show an increase in the number of PD studies in science education in recent years. Most PD programmes are aimed at enhancing teacher cognitions as well as classroom practice. Most recently, there seems to have been an increase in programmes that also aim at improving student outcomes through PD. All studies applied most of the characteristics drawn from research on what makes PD effective. However, school organisational conditions were not usually taken into account. Moreover, there has been a very little research on the role of facilitators and their impact on the outcomes of a PD programme.     

Fostering innovation through collaborative action research on the creation of shared instructional products by university science instructors

ABSTRACT

The purpose of this study is to profile four university science instructors who utilized action research as a means of learning how to develop and integrate a novel curriculum innovation – engineering design – in their science courses. Data included curriculum maps, lesson plans, notes from group meetings, and instructor reflections. Data analysis included document review and content analysis. Findings from this study suggest that action research effectively enabled the instructors to 1) establish shared ownership of the project goal – to improve preservice teachers’ learning of science through engineering design; 2) continuously test, revise, and recalibrate their shared instructional products; and 3) leverage multiple sources of innovation. Knowledge generated and used by the instructors represented different kinds of knowledge and distributed expertise resulting in products that were more useful and of higher quality than products created by individuals working alone. Consequently, this resulted in increased use of the products and increased instructor commitment to improve them over time. By simultaneously engaging in research and consequently taking specific action to inform their practice, science instructors in this study successfully created shared instructional products that both guided and enhanced their classroom teaching.     

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.

Spinning a Web (Case) Around Professional Standards: Capturing the Complexity of Science Teaching

This study examines the intersection of two key reform ideas in science teacher education – professional teaching standards and the use of case methods. In this article, we track the historical development of what can be called second wave teaching standards and describe how those standards can be exemplified through multimedia web cases of science teaching. We describe a web case development project in which a group of experienced secondary science teachers work together over several months to video their own classes, and assemble video and audio commentaries of their lessons based on a set of science teaching standards. We conclude that the project was a rich professional development experience for those involved. Further, as the teaching standards movement gathers momentum in Australia and elsewhere, we contend that high quality multimedia cases linked to a standards framework show considerable promise as a vehicle to assist science teachers to reflect on their practice.     

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.

Teaching about sustainability through inquiry-based science in Irish primary classrooms: the impact of a professional development programme on teacher self-efficacy,competence and pedagogy

Abstract

Research suggests that innovative and engaging professional development is instrumental in supporting teachers in developing their competence and confidence in teaching sustainability. An international initiative was developed to explore whether a competencies-oriented Education for Sustainable Development (ESD) professional development model was transferable across three different international contexts (Ireland, Germany and Mexico). This paper reports on the adaptation of this model within the Irish context, through the development of an innovative professional development programme for primary teachers. Through a mixed-methods approach which gathered data via pre- and post-programme surveys, teachers’ reflective journals and post-programme group interviews, the paper explores Irish primary school teachers’ experiences of, and attitudes towards, teaching sustainability through science education after participation in a professional development programme. The findings suggest that this programme, structured around the existing evidence for effective professional development in science education and ESD, positively influences teachers’ self-efficacy, supports teachers’ critical engagement with sustainability competencies and promotes the development of transformative pedagogies for sustainability through Inquiry-Based Science Education.     

Coherence,contradiction, and the development of school science identities

This study demonstrates the potential for collaborative research among participants in local settings to effect positive change in urban settings characterized by diversity. It describes an interpretive case study of a racially, ethnically, and socioeconomically diverse eighth grade science classroom in an urban magnet school in order to explore why some of the students did not achieve at high levels and identify with school science although they were both interested in and knowledgeable about science. The results of this study indicated that structural issues such as the school's selection process, the discourses perpetuated by teachers, administrators, and peers regarding “who belongs” at the school, and negative stereotype threat posed obstacles for students by highlighting rather than mitigating the inequalities in students' educational backgrounds. We explore how a methodology based on the use of cogenerative dialogues provided some guidance to teachers wishing to alter structures in their classrooms to be more conducive to all of their students developing identities associated with school science. Based on the data analysis, we also argue that a perspective on classrooms as communities of practice in which learning is socially situated rather than as forums for competitive displays, and a view of students as valued contributors rather than as recipients of knowledge, could address some of the obstacles. Recommendations include a reduced emphasis on standardized tasks and hierarchies, soliciting unique student contributions, and encouraging learning through peripheral participation, thereby enabling students to earn social capital in the classroom. © 2010 Wiley Periodicals, Inc.

Globalization and science education: The implications of science in the new economy

Science has seen considerable change in recent decades with the emergence of a new economic and sociopolitical contract between science, the nation, state, and private commercial interests. Generally regarded as having been precipitated by globalization, these changes in the sciences are beginning to be documented by a range of commentators. Clearly, science's changing forms hold profound implications for the development of science education. As there is little science education scholarship exploring the implications sciences' altering forms, this paper attempts to investigate the relationship at more depth. Detailing this relationship is important because it can help formulate new questions, and methods for their investigation, relevant to the work of science education in the newly global world. © 2008 Wiley Periodicals, Inc.

Studying science teacher identity: current insights and future research directions

Over the past 10?years an increasing number of articles have been published in leading science education journals that report on research about teacher identity and describe interventions that support teacher identity development. My purpose in this review paper is to examine how the construct of science teacher identity has been conceptualised and studied in science education. In doing so, I synthesise the findings of 29 empirical studies on teacher identity within the field of science education in an attempt to respond to the following questions: (a) In what ways have researchers used the construct of teacher identity to examine science teacher learning and development? (b) What approaches to supporting science teacher identity development have been documented in the literature? Following that, I identify gaps and limitations in the existing literature and I offer recommendations for future research in the area of science teacher identity and identity development: (a) studying teacher identity as a process; (b) connecting science teacher identity research and reform recommendations; (c) conducting large-scale, longitudinal and life-history studies; and (d) examining teacher identity enactment in school classrooms.     

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

Profiles of change in motivation for teaching in higher education at an American research university

The current study employed an emergent theoretical model of teaching role identity and motivation to investigate the change in conception of and motivation for teaching in higher education of research graduate students who teach in the United States. Fifteen participants took a graduate-level seminar as part of a two-course teaching professional development (PD) program. Qualitative content analysis of the participants’ pre-seminar and post-seminar reflective essays focused on change in the theoretical model’s components – participants’ goals, self-perceptions, epistemological beliefs, and action possibilities – and their alignment. The findings suggested four kinds of change in each component, ranging from dramatic change to reversed change, as well as three general profiles of change labeled ‘Transformation,’ ‘Elaboration’, and ‘Stagnation’. The model proved useful in conceptualizing the change in participants’ teaching-related conceptions and motivation and could provide a guide for future research on teaching motivation and for designing and evaluating teaching PD in higher education.
