      The reality is that the typical classroom teacher still uses a blackboard and chalk. Indeed, despite the excitement over high-tech devices, most classroom equipment is decidedly low-tech: small-screen television sets, mimeograph machines, monaural phonograph record players, overhead projectors with grease pencils, 16-millimeter projectors, reel-to-reel tape players, filmstrip projectors.


  • German: Overheadprojektor
