Olá Gabriel. Eu vou intentar ajudá-lo com o seu texto. (Asim você vai ver as palabras correctadas) (Most) students own a cellphone. Competing (against) such a device has not been easy for teachers, (mostly because of) the increasing access to social media. However, if used (correctly/wisely), it has much to add to the education in general. It is well known that it can make classes more interesting and studying a little more fun, since it (can) enable students to take pictures, watch and record videos, take tests, etc. Besides, its advantages are undeniable: the student does not need to copy off the board - just a click and all the necessary (information is) in a photo, which can save them some time. In addition to that, it can be an ally in the search of (more additional information) that help improve the learning. For (these) reasons , teachers and professors should tap (on their) cell phones rather than (forbid their) use in class.
