Mobile phone bans have been coming into force in schools across much of the country in recent months, with tighter restrictions expected to become widespread in 2024.
The move follows growing demands for stricter policies in the wake of a series of recent reports highlighting the damaging impact of the devices on learning.
Unesco, the UN's education, science and culture agency, warned in July that smartphones cause distraction, a risk to pupil privacy and lead to cyber-bullying.
In Scotland, a long-awaited study on deteriorating school behaviour in November found it was one of the most frequently raised issues among secondary teachers, with 88 per cent dealing daily with pupils looking at phones instead of paying attention in class.
There have also been growing concerns about the filming of violent incidents among pupils, with footage then being posted on social media.
Meanwhile, in December the Organisation for Economic Co-operation and Development (OECD) linked rising misuse of such technology to the declining performance of many countries, including Scotland, in the respected Pisa tests of the performance of 15-year-olds in maths, science and reading.
In England, Education Secretary Gillian Keegan has already unveiled plans to ban phones in schools.
