Some classrooms in the school building are in session. In almost every class, a small number of students "play" with their mobile phones buried in their heads. But the probe and Advantage Of Cell Phone Blocker on the classroom wall are not turned on. There was no notice from the school asking them to turn on their probes and signal jammers during class. Installed mobile phone jammers and transformed it into a postgraduate examination room "The students misunderstood. The installation of probes and mobile phone signal jammers in the classroom is not to prevent students from playing mobile phones in the classroom." Due to the frequent leakage of graduate entrance examinations in my country in recent years, The Ministry of Education required the examination room to install preventive equipment, and the Jiangsu Provincial Department of Education and Finance Department decided to build a standardized examination room.
Nanlin University is an important test site for the Nanjing University Graduate Entrance Examination. Recently, cell phone jammer and monitoring probes were installed in 140 classrooms of the school, which were transformed into standard examination rooms. Each standard test room needs to install signal jammers and probes to ensure that all mobile phone signals in the test room are completely shielded, and the monitoring range has no dead ends. As a result, some large classrooms are "divided" into multiple test rooms. The 140 classrooms of Nanlin University were finally "reconstructed" into 270 standard examination rooms. In recent years, in order to ensure the fairness and impartiality of examinations, Advantage Of Cell Phone Blocker and metal detectors have been widely used in various large-scale examinations, and the college entrance examination is no exception. Most people believe that the combination of cell phone jammers and metal detectors undoubtedly provides a double guarantee for the safety of the test environment. However, an unexpected experience in this year's college entrance examination invigilation made the author feel that the scientific and rational use of mobile phone jammers and detectors is an important prerequisite for examination safety, otherwise there will be unintended consequences.
