  Digital educational games have demonstrated large variations in learning
outcomes and transfer. Furthermore, educational games are usually embedded in a
larger educational setting. This case study evaluates in detail a lesson around
an educational game designed to foster transfer. The game, Newtons Race, is an
intrinsically integrated game on Newtonian mechanics. The learning goal of the
lesson is understanding and applying the relationship between forces and
motion. Outside of the game, lesson activities include a debriefing session, a
generalisation assignment, and an assignment on transfer situations. This
lesson was evaluated using a mixed-methods approach. A pre-post test design
(N=27) demonstrated a large significant learning effect (p = .002, d = .908).
Transfer, as measured within the posttest, was also fostered significantly. In
the qualitative part of the study, students written statements on the
worksheets and students utterances during the discussion were analyzed using
open coding. 79 percent Of all quotes were coded as scientifically correct.
