First, before the college entrance examination, the teacher checked carelessly, and the metal detector did not detect the mobile phone on the students. The college entrance examination is called the fairest exam in China. In order to maintain the fairness of the exam, before entering the college entrance examination, a teacher will search you and a metal detector will scan you all over. And as early as a few years ago, silent entry into the examination room was implemented, which means that you can't have a trace of metal on your body, otherwise you can't enter the college entrance examination room. However, in Gansu, there is such a candidate. In the process of taking the college entrance examination, he photographed the college entrance examination paper with his mobile phone and sent it to QQ group, even paying a high price to buy the answer. This kind of behavior is illegal. A large part of the reason why candidates can bring their mobile phones into the examination room and log on to QQ is that the invigilator didn't check carefully before the entrance of the college entrance examination, and the metal detector didn't detect the mobile phones on the candidates, so candidates can bring their mobile phones in quietly. After the student's cheating incident was exposed, the Ministry of Education said that it had reported the case and eventually punished the student, declaring that his math score was invalid and he could not take the next exam. The Ministry of Education also said that it would thoroughly investigate the irresponsible behavior of the invigilator.
Second, the reason why cheating candidates can bring their mobile phones into the examination room and log in to QQ may be that the shielding instrument in the examination room has been forgotten to open. There are no electronic products in the college entrance examination room, so students are not allowed to bring anything into the examination room. Gansu candidates cheated with their mobile phones during the math exam, and photographed the questions and sent them to QQ group, indicating that there was a signal in the college entrance examination room. The reason for this phenomenon may be that the invigilator forgot to turn on the shielding instrument in the college entrance examination room. This is also the responsibility of the invigilator, so we should punish the invigilator in the examination room.
To sum up, Gansu college entrance examination students cheat in mathematics, and the reasons why candidates can bring their mobile phones into the examination room to log in to QQ are as shown above.
