Description

CosmiClean is a game "designed ... to teach secondary school and university students the principles of separation processes for recycling materials", in which players build separation chains of conveyors, separators, and receptors across cargo levels with corrective feedback. For the intervention, three recorded videos (about 23 minutes each, 13 game levels) showed a male peer model playing the same script with enjoyment, frustration, or a neutral expression, filmed from a first-person perspective and hosted on Edpuzzle.

  • Participants watch the video carefully and cannot skip it; a manipulation check after the posttest verifies perceived emotion

Constraints

Target Learners

  • Secondary school and university students

Learning Goals

  • Chemistry separation processes: using nine separators, twelve materials, and eight properties
