Abstract

This device uses an IBM Port-A-Punch board as a teaching device. The standard Port-A-Punch board and stylus are altered to allow the use of three types of cards simultaneously: a question card 10, a pre-scored Port-A-Punch answer card 11 and a master card 12 with the correct answer choices prepunched. Card 11 is inserted at its regular location on the rubber tee strips 13. For convenience, card separator plate 14 is positioned over card 11. Plate 14 contains a matrix of holes 15, one for each card hole position, and edge guides 16 which allow the question card to be placed in registration above card 11. Question cards 10 can be successively placed and removed from the top of plate 14 without dislocating card 11. Plate 17 is fitted to the bottom of the Port-A-Punch board to support master card 12.

11. Question cards 10 can be successively placed and removed from the top of plate 14 without dislocating card 11. Plate 17 is fitted to the bottom of the Port-A- Punch board to support master card 12. Holes corresponding to Port-A-Punch hole positions are in plate 17 and the plate and frame member 18 hold card 12 in registration below the other cards. The Port-A-Punch stylus 19 is elongated to provide the penetration into the holes in plate 17.

In the teaching application, the student reads the statements and facts or both, the questions and the answer choices on card 10. After selecting an answer, the student places stylus 19 in the corresponding prepunched hole 20 in card 10. Stylus 19 passes through the card 10 hole and plate 14. The student's answer is recorded, with a slight resistance, as it pushes out the Port-A-Punch chad in the f...
