Definition
Epistemic feedback is a feedback provided by a learning environment specific to the piece of knowledge at stake and its learning characteristics. The computation of an epistemic feedback involves data from the learner, the pedagogical models, and the knowledge domain.
Comments on the history
The origin of the expression “epistemic feedback” can be traced in the philosophy of science (Margeneau 1978 p.287) where it denotes the feedback whose meaning requires interactions between tangible characteristics of the environment and users' knowledge or expectations. It is used in HCI research which takes into account three functional roles of human gestures: semiotic, ergotic and epistemic; the latter referring to the epistemic function of gesture which “allows humans to learn from the environment through tactile experience.” (Crowley and Martin 1997 p.1). The concept of epistemic feedback was introduced in TEL research, in the context of the design and study of virtual reality and simulation for professional training, to characterize feedback which allow learner to perceive and analyze his or her action in relation to the knowledge at stake (Luengo 2009 p.26 sqq).

Stellan Ohlsson (1996) coined the term epistemic activities, to account the fact that “human beings employ their understanding, not in action, but in the generation of symbols” (ibid.p.95). He included activities such as describing, explaining, predicting, arguing, etc. In line with this approach, CSCL research adopted the term epistemic interaction for those interactions which are “potentially concerned with the expression and critical examination of foundations for proposals” (Baker et al. 2001).
The development of high quality simulations and their use for learning opens a new possibility to support the acquisition of tacit knowledge, which as well is potentially concerned by a critical examination of foundations for action. Epistemic interactions related to tacit knowledge, often ill-defined (Lynch et all. 2009), in the context of the use of simulation, aim at taking into account epistemic activities, especially controls during the action, in generating an epistemic feedback. For example, in the case of visual and haptic perceptions, the identification of the visual controls and their rational (what knowledge is mobilized to allow this visual verification) makes possible generating an epistemic feedback linked to the associated knowledge. For this kind of interaction it is not necessary to propose a complete description of the action—what is actually impossible in ill-defined domains—but to identify the relevant controls of the actions from a learning perspective.
