摘要：This theoretical paper defines and explores the concepts of transductive links and transductive chains, as part of the theoretical framework of social semiotics. Social semiotics stems from the multimodal framework, which provides a theoretical perspective, constructs, and a language to describe a shift of semiotic material within or between semiotic systems, such as rewriting a text or moving from a function to a plot. Within this framework a shift of semiotic material between two such systems is referred to as a transduction. This paper aims to expand on the concept of transduction by identifying a theoretical contribution to the modeling of this process, referred to as a transductive link. This link is suggested to affect the transduction process and the resulting learning experience. For example, when plotting measurement data, a computer program can be employed to read the data and to transform the data into pixel information. In this case, programming, or the act of programming, acts as a link between the two resources in the transduction process—a transductive link. In other cases, multiple transductions can be performed one after another resulting in these links creating what we define as a transductive chain. By observing and analyzing the use of different semiotic systems in different learning situations, transductive links and chains can be identified and examined. From this identification one has the possibility to find weak links in the transductive chain and address them accordingly. As such, we suggest that transductive links and chains are powerful tools to be able to understand students’ learning experiences.
