Animation is widely acknowledged for dynamically visualizing information and has been increasingly used in educational context. However, the growing presence of educational animation has not been accompanied by well-informed studies that focus on the semiotic features of animation. An emerging perspective influenced by Social Semiotics and Systemic Functional Linguistics greatly complements the current trend of animation studies in the field of science education. Studies taking that perspective model animation as stratified systems (consisting of an expression plane and a content plane) (...) of meaning-making options. Building on their work, this paper further develops the systems of animation on the two planes. Besides the concept of stratification, this paper also introduces a metafunctional perspective for the modeling of animation, focusing on building the ideational meaning system and textual meaning system for animation on the content plane based on an examination of online science animations. It is found that educational animation is not homogenous: animation can construe different human experience and can be used to fulfill different functions. The paper closes with a discussion of the advantages of adopting a stratified metafunctional model in studying animation and the implications for future studies in the field of multimodal semiotics and science education.

A variety of semiotic resources makes the construction of scientific knowledge possible and meaning-making resources are conveyed by certain semiotic modes. Next, numerous studies have demonstrated the pedagogical importance of gestures in the demonstration of scientific knowledge in the classroom. Drawing on social semiotic systemic functional theory and legitimation code theory, this study explores the types and the role of gestures in the semiotic construction of scientific knowledge in pedagogic semiosis and their pedagogical values for the meaning-making of science content. (...) With this aim, a gesture observation protocol (GOP) is developed to annotate and analyze data. Two science lectures, which are broadcast remotely for middle school students including gifted students, are observed. Systemic Functional Multimodal Discourse Analysis (SF-MDA) method is employed to analyze and evaluate data. Results demonstrated that the deployment of gestures that contributes to the construction of scientific knowledge is low and deployed gestures mostly do not have pedagogical value. It is recommended that teachers should be more conscious and educated about deploying gestures to present scientific knowledge efficiently. (shrink)
