PURPOSE:To improve the understanding and level of students by arranging transmitters which differ in frequency on desks and operating them by the students for answering, and then displaying the answering state as well as statistics of all the students in a classroom on the platform. CONSTITUTION:Answering machines 1 which has a substrate 2 with a circuit operated by a charging type battery 3 for a power source and a transmitting antenna 4 for sending an electromagnetic wave internally and selection switches 5 for selecting answers externally and differ in frequency are placed on the respective student's desks. An electromagnetic wave sent by each answering machine is received by a receiving antenna 14 and selected with a control switch 18, and a center control computer 19 performs calculation on the basis of respective data held in a data holding circuit 24 to display commanded statistics, etc., on a graphic display screen 20. Consequently, total data is displayed in percentage representation and the deviation value of individual statistics from the total data is displayed to know the learning states of the students, thereby improving education.
