摘要： An educational apparatus, of the language laboratory type, includes a master control unit operated by the teacher and which is associated with a plurality of student terminal control units so that the teacher can monitor the student's responses and immediately answer any questions by the students. Each terminal control unit includes any information signal input for receiving an information signal, such as a question from a student, an information signal transmitting circuit adapted to receive the information signal from the respective input and to transmit the same to a monitoring device, such as a headphone set, at the master control unit and a call signal input for supplying a call signal, as when a student has a question, to the respective transmitting circuit and also to a respective indicating device, such as a light emitting diode, at the master control unit, for indicating that a student has a question. The master control unit includes an incoming call switch for making operative the respective transmitting circuit when a call signal is supplied thereto, whereby to pass the respective information signal through the operated transmitting circuit to the monitoring device of the master control unit. The educational apparatus also includes a mobile control unit for controlling the operation of the master control unit, in the same manner as described above, while the teacher walks among and observes the students.
