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

Periódico: International Journal of Science Education

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:
While a solid understanding of science content knowledge is important in developing expertise in science teaching, it is not necessarily a sufficient condition to teach science effectively in elementary schools. Teachers need to have the ability to transform their knowledge into forms learnable by students. Based on this perspective, the current study explored how science content knowledge was pedagogically transformed in Korean elementary classrooms. Data sources included video-recorded science lessons of five elementary teachers in a metropolitan city of Korea. The analysis of the data revealed that the Korean teachers often engaged in transforming science content knowledge by means of different semiotic modes, including language, pictures, materials, actions, and their complex combinations. Further, their representations of scientific knowledge were in diverse forms, such as personifications, analogies, quiz questions, pictorial models, diagrams, animations, real-life examples, hand demonstrations, videos, flash tools, and songs-and-dances. Future research involving a wider range of participants, such as students, content specialists, and teachers with weak and strong content understanding, was suggested to confirm the findings of this study and find more various ways of pedagogical transformation of science subject matter knowledge.
