Abstract:
Many preservice primary teachers have inadequate science knowledge, which often limits their confidence in implementing the subject. This paper proposes a new way for preservice teachers to learn science by designing and making a narrated stop-motion animation as an instructional resource to explain a science concept. In this paper, a simplified way for preservice teachers to design and make an animation called ‘slowmation’ (abbreviated from ‘slow animation’) is exemplified. A case study of three preservice primary teachers creating one from start to finish over 2 h was conducted to address the following research question: How do the preservice primary teachers create a slowmation and how does this process influence their science learning? The method of inquiry used a case study design involving pre- and post-individual interviews in conjunction with a discourse analysis of video and audio data recorded as they created a slowmation. The data illustrate how the preservice teachers’ science learning was related to their prior knowledge and how they iteratively revisited the content through the construction of five representations as a cumulative semiotic progression: (i) research notes; (ii) storyboard; (iii) models; (iv) digital photographs; culminating in (v) the narrated animation. This progression enabled the preservice teachers to revisit the content in each representation and make decisions about which modes to use and promoted social interaction. Creating a slowmation facilitated the preservice teachers’ learning about the life cycle of a ladybird beetle and revised their alternative conceptions.

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.
