Identification and evaluation of reliability questionnaires. This method will provide a fast, convenient and effective method to improve the credibility and data quality of the online questionnaire survey.

The invention relates to an intelligent teaching system comprising a question setting main terminal, a question answering sub-terminal, a question database and a cloud host, wherein the question setting main terminal, the question answering sub-terminal and the question database are wirelessly connected with the cloud host. The cloud host comprises a processor, a comparison module and a statistical module. The question setting main terminal comprises a first display screen, a first identity identification module used for identifying the identity of a teacher, a question selection module used for selecting questions, a lesson preparation module used for preparing lessons, an examination module used for selecting examination questions to form an examination paper, a first input module and a printing module connected to a printer for printing. The question answering sub-terminal comprises a second display screen, a second identity identification module and a second output module. A teacher has more reference objects for selection of lesson preparation content and selection of examination paper questions, can roughly master the teaching results and thus can achieve a targeted effect and effectively improve the teaching quality. The teacher can also clearly master the learning condition of an individual student according to the statistical condition of the statistical module and provide targeted tutorship.
