ABSTRACT:
A series of cards, bearing as learning units as for programmed instruction respective frames of information, questions or problems and answers or solutions, are arranged in like orientation and in ordered sequence in a stacked pack for a preferred embodiment disposed in a stack-form-maintaining container. A perforation margin of each card has a hole corresponding to a correct answer response, or additionally for incorrect responses, a slot or slots coincident with an underlying card hole. The holes or slots are arranged at answer selection locations designated adjacent the perforation margins of the cards, so that withdrawal shiftability or not of an individual exposed top card, by a response selection rod penetrating a margin concealing strip, indicates a correct or a wrong answer; or with the exposed card not withdrawable, by the rod passing through a slot thereof to a hole of an underlying further card, the withdrawability only of the latter enables branching in the instruction program, thus providing a simple, low cost apparatus, convenient for self-instruction and having reuseable frames. Variant simple containers are shown for maintaining the cards in individually removable stacked form and affording a perforation margin covering element; and the cards on one or both sides may each present plural fields of respective frame material.
