Grasping the dynamics of molecular phenomenon appears to be rather challenging for
students in the context of life science. To pursue the origin of such difficulties this paper
investigates students’ (n=43) meaning making, in interaction with peers and an animation,
of the dynamic process of ATP-synthase. To support this inquiry we introduce the CharMframework
(Characteristics of Metaphors), which accounts for students’ experiences of
metaphors while interacting with external representations (ERs) when trying to make
meaning of molecular phenomena. Student-expressed metaphors are outlined and related to
the animator’s intentions while designing the animation. The analysis shows that some of
the used metaphors possess in-built problematic characteristics that could act as potential
problems for learning. For example, the metaphors machine and watermill possess
problematic characteristics that are a possible reason for students’ difficulties with understanding
the ATP-synthesis as a reversible and non-deterministic process. Furthermore, we
also conclude that students’ use of metaphors is highly influenced by the ER, which is
designed according to the animator’s internal representation of the scientific phenomenon
and his intentions. The challenge associated with designing educational representations that
sufficiently represent molecular processes is somewhat similar to the challenge student face
while linking the characteristics of metaphors to the molecular processes. The CharMframework
can assist in the design process by allowing designers to reflect on how ERs
could be interpreted or misinterpreted and also guide teachers’ choice of educational
representations.
