A group of UK teachers are urging parents to limit their children's time on tablets and other technology, as they claim a rising number of young students lack the motor skills needed to play with building blocks while older students are unable to take written exams with pen and paper. According to The Telegraph, the Association of Teachers and Lecturers wants parents to turn off the Wi-Fi at night before bed so students get a good night's sleep instead of playing on tablets all night. The association claims that younger students as young as three or four can swipe on an iPad screen, but have little or no dexterity in their fingers to use building blocks. As for the older students, the association said their attention spans are limited in the classroom due to overexposure to technology. They further claimed that these students can't implement the skills they read in their textbooks, but have exceptional technical skills when it comes to consumer electronics.
