What does it mean for students to scan the code backwards?

Reverse code scanning means that students shoot the QR code provided by the teacher through the mobile phone camera and convert it into digital or text information in order to participate in classroom interaction, answer questions or obtain courseware and other resources.

This kind of classroom has certain advantages, such as enhancing students' ability to screen, judge and use Internet resources, and at the same time improving students' participation and enthusiasm and stimulating learning motivation.

Of course, there are also some problems and hidden dangers in reverse scanning code. For example, students may use other QR code scanning software to analyze QR codes, but not all of them are safe and feasible. Therefore, schools and teachers need to strengthen classroom management and guide students to use anti-code scanning technology correctly.
