DIDACTIC AID IN PARTICULAR THAT FOR USE AT PRIMARY SCHOOLS

摘要

A didactic learning device representing a development of the state of the art because of the immediate self control provided to users upon completion of tasks. Thus the users are encouraged to continue their work if the solution is correct or to rethink the solution if wrong. The learning device comprises a plurality of foils (9) with various tasks (addition, subtraction, lower multiplication tables etc). According to the specific task complex, the learning device, which consists of a base plate (1) and various disks (3,4,5,6), is covered by the foil (9). Fundamental to the invention is the use of a rotatable disk for units and tens (4, 3) to adjust the obtained result according to the usual computational process organized in units and tens. If the solution is right and the corresponding adjustment of the learning device has been effected a drop pin moves through the holes in task foil (9) over the holes in the disks (1, 3, 4, 5, 6) and indicates to the user the right solution to the task. The learning device can be used for subjects such as mathematics, but also, for example, for German (correct spelling), geography, biology etc (correct correspondence of results to given facts). The knowledge acquired can be checked by using the device in a playful manner.
