@RAHEELSAHITO Dear Raheel, I partially agree with you. Even though, mobile phones in the classroom distract the students, it's also concerned with the teacher and how he/she allows or guides students to use that (powerful, innovative, resourceful, and on-demand device) called mobile for some big purpose.
There are pros and cons to everything in the world, and it depends on how we use/consume it. Suppose I as a teacher, assign my students to prepare a 2-minute presentation by choosing any five topics from your eighth-grade science book's first chapter, and xyz will be the main topics that will marked as your sessional grades. Here, I divide three student per group and each one will receive equal marks on their collective as well as individual efforts. Now comes an extra instruction for all of the students: "Everyone of you will use your mobile phone and internet connection, and all of you are authorized to use any app or internet resources to make or prepare your presentation content unique and engaging.
This way, students will start interacting with each other and will also fill the gap if someone does not have a mobile phone. Now, they may have learned how to work in groups and carry out meaningful discussions, technical skills, exposure to vast, unlimitedly available resources, and many more.
These activities of using phones in a controlled environment where everyone works with peers provide a better learning experience for both students and teachers.
There are many things, which may be opposite to my stance and opinion but I would also add that excessive availability and allowance of digital tools in 6thβ8th grade levels must be operated in focused way.
Thank you for reading my comment.
