Tamcq q17

  • Option : C
  • Explanation :

    An epidiascope is a projected teaching aid.

    • Why C fits: It uses light and lenses to project an image of material onto a viewing surface.
    • Why the others differ: A blackboard, diorama, and globe are viewed directly rather than projected onto a screen.
    • Revision point: Classify an aid by how learners see the material. A physical model can be valuable for teaching, but usefulness does not make it a projected aid.
