Influencing Intended Teaching Practice: Exploring pre-service teachers’ perceptions of science teaching resources

Título do artigo: Influencing Intended Teaching Practice: Exploring pre-service teachers’ perceptions of science teaching resources

Abstract
Many researchers have identified and expressed concern over the state of science education internationally, but primary teachers face particular obstacles when teaching science due to their poor science background and low confidence with science. Research has suggested that exemplary resources, or units that work, may be an effective way to support primary teachers. This study explores the effect of one such resource on the intentions of pre-service primary teachers to teach science. The resource in question is Primary Connections, a series of learning resources produced by the Australian Academy of Science specifically designed for primary science. Evaluative studies of Primary Connections have indicated its efficacy with practising primary teachers but there is little evidence of its impact upon pre-service teachers. The purpose of this study was to investigate how effective these quality teaching resources were in influencing the intentions of primary pre-service teachers to teach science after they graduated. The theory of planned behaviour  highlighted the linkage between the intentions of the pre-service teachers to teach science, and their awareness of and experiences with using Primary Connections during their education studies. This enabled key factors to be identified which influenced the intentions of the pre-service teachers to use Primary Connections to teach science after they graduate. The study also provided evidence of how quality science teaching resources can be effectively embedded in a teacher education programme as a means of encouraging and supporting pre-service teachers to teach science.

Abstract:
This study deals with the participation of 10 upper secondary chemistry students, aged 16–17, and their chemistry teacher in a pharmacochemistry research community on anti-allergy medicines at VU University, Amsterdam, The Netherlands. Participation of students in scientific research raises the question of how to bridge the gap between an upper secondary school inquiry practice and a scientific research practice. To bridge this gap, a design based on 6 principles derived from an educational model of a community of learners was proposed. The study first aimed at revealing whether the proposed principles were necessary according to the students, their teacher and three pharmacochemistry researchers for successful participation of the students in the research community. Second, the study examined whether the students' understanding of discipline-specific content knowledge, interest in scientific research and knowledge about the nature of science changed during the course of the study. Data were obtained from questionnaires, interviews and video tapes. The results indicated that according to the teacher all 6 principles were necessary to bridge the gap, whereas according to the students 1 principle and according to the pharmacochemistry researchers 2 principles were necessary but difficult to achieve. Furthermore, all students gained discipline-specific content knowledge. Their interest in scientific research exhibited a positive change and their knowledge about the nature of science increased. The implications for further research and practice are discussed.

Abstract:
Science education reform documents identify nature of science (NOS) as a critical component of scientific literacy and call for universities, colleges, and K-12 schools to explicitly integrate NOS learning into science curricula. In response to these calls, this study investigated the classroom practices of nine graduate assistants (GAs) who taught expository and inquiry laboratories that implemented an explicit and reflective (ER) pedagogy to teach NOS. The purpose of this qualitative study was to better understand the experiences that enabled or inhibited GA implementation of an ER strategy in a college setting. The findings revealed that achieving quality implementation in this setting was very difficult. Factors such as GAs' ability to foster meaningful classroom discussions, laboratory logistics (e.g. lack of time and supplies), and the value undergraduates and GAs saw in learning about NOS were identified by GAs and observed by the researchers as barriers to the technique maximizing its potential. Thus, for meaningful infusion of NOS into science curricula, pedagogical support for GAs to manage meaningful classroom discussions in support of NOS or other complex topics is recommended for an ER approach to NOS learning to be successful in college settings.
