Fig. 4: Key steps in the porcelain-making digital game.

a Mining interface with raw materials and a cart for collection. Students can drag porcelain-making raw materials into the cart. After dragging correct or incorrect materials, the virtual craftsman prompts and explains. b Crushing interface showing tools and assembly instructions. Students must assemble and start the water-powered trip hammer to crush raw materials. c Firing interface with kiln controls and a temperature gauge. Students need to adjust the kiln temperature to fire porcelain. d Fining interface for glazing color comparison. Students observe sample colors to determine heat control during firing. Throughout these steps, students complete tasks independently but can seek hints from the virtual craftsman when needed.
