DEFINITION

Classification: 434/327

Correctness of response indicated to examinee by self-operating or examinee-actuated means:

(under subclass 322) Subject matter wherein after an examinee has responded to a presented question or problem, such as by manipulation of some means (e.g.., key, etc.), an indication of the correctness of the response is given.

(1) Note. The indication may be direct, such as by illumination of a green light, or indirect, such as by presentation of a new question, or it may be a negative indication, for example, the illumination of a red light or the failure to present a new question after an incorrect response.
