Problems solved by technology

[0002] At present, among the smart devices used in classroom teaching, there are three ways to answer questions in the classroom. One is to use paper answer sheets, but it is impossible to analyze students’ answers in real time, and teachers need to spend more time entering the system. The second is to use answer cards Clicker solution, the clicker is easy to distract the students' attention, and it is easy to be damaged by human beings. It is necessary to bind the identity of the student, and it is troublesome to change the student and re-bind it.

specific Embodiment

[0071] Using a teaching system, student information and test question information can be preset in the teaching system. Student information includes student number, class number and other identity information that can be associated. Test question information includes test questions and standard answers to test questions. Open, the data collected by the camera can also be directly transmitted to the teaching system. During class, open the teaching system on the all-in-one computer, and show the test questions that students need to practice. After the students answer the questions, they lift up the tab to display the answers. At this time, the wide-angle camera above the blackboard collects the face information of the students and the information of the selected tabs in the entire classroom, and uses face recognition technology and optical character recognition technology to carry out information recognition to complete the binding of student identities and answer results , and ...
