The teacher's use of jammers to improve student performance is an improvement in the classroom
I feel sorry for a Florida teacher who used cell phone GPS jammers to intercept students' calls in class so they could focus. When children look at the screen instead of the landscape.
The jammer blocked communications with the cell tower on Fivay College's campus, and both the service provider and the school became concerned about safety. Liptak bought the jammer online and found it was legal to use.
According to WTSP-TV: Pasco County School District spokeswoman Linda Cobb said, "Verizon came to the school and said someone was jamming the device because of a disruption in cell service in the area."
The school believes that students should not be allowed to bring cell phones to class as parents believe cell phones are necessary and can increase safety.
However, a new study in the UK shows that using cellphones in the classroom is not conducive to learning, especially for students with poor academic performance.
The study was published in May and read:
We found that students' test scores increased by 6.41% (standard deviation) after using wifi jammer to ban cell phones. Our results show that the academic performance of students will not improve significantly if the ban is not implemented across the board. Moreover, this influence is borne by the most disadvantaged and poorest students. The student with the lowest score in the previous quarter received 14.23% of the standard deviation, and the student in the quarter with the highest call was unaffected by call blocking, either positively or negatively. The results show that underperforming students are more likely to be disrupted by cellphones, while excelling students are able to focus on class regardless of cellphone policy. Schools can significantly reduce the academic inequality by banning the use of cell phones in schools. Therefore, by allowing cell phones in schools, New York may inadvertently increase inequality of outcomes. We offer several robust controls, such as event studies, placebo bans, student enrollment change tests, and a range of alternative outcome indicators.
