Reflection is an essential concept in cultural-historical psy- chology, developed by Lev Vygotsky and his colleagues in the 1920s and 1930s. For Vygotsky individual development hap- pens in interaction with others, and conscious reflection on that interaction. (Vygotsky 1978) Social-constructivist learn- ing theories emphasize the significance of discourse and knowledge building in the light of activities such as returning to and reflecting on (e.g., Paavola et al., 2004; Senge, 2006). Schön (1983) discusses the ability of experts to reflect on their activity in and on action. Carefully designed new media tools may support reflection, as they can be used to record dialogue, to step back, evaluate and compare it. This poster presents three new media reflection tool prototypes for learning, and illustrates one of them below.
