salantis [7]

La respuesta correcta para esta pregunta abierta es la siguiente.

Las situaciones más comunes en las que los estudiantes usan el teléfono celular de la manera incorrecta son las siguientes.

-Se la pasan perdiendo el tiempo jugando sus juegos de video.

-Se la pasan viendo videos de sus series favoritas.

-Se la pasan escuchando música.

-Se la pasan ch*teando gran parte del tiempo.

-Se la pasan en las redes sociales, entrando a las páginas de los demás.

Todas estas actividades los distraen y no les proporcionan nada productivo. Les quitan el tiempo y no les aportan nada que valga la pena.

Por esa razón, tanto en casa como en la escuela, padres y profesores deben ser muy estrictos en monitorear el uso que los hijos le dan al teléfono celular.
