A local primary school is considering using tablet computers(平板电脑)in all classrooms from next year. The following text has been written by a teacher at the school.

Should we use tablet computers in the classroom?

The use of tablet computers(or simply“tablets”)in the classroom has become an increasingly popular choice in many primary schools across the country, including many in our local area. It is important that we consider this opportunity, but we must also be a 1. of the problems.

On one hand, there are many a2.to use tablets in the classroom.

Firstly, tablets could improve productivity( 效 率 )during the school day. Because of their familiarity with computers and mobile phones, many of our students can type faster than they can write by hand. T3. , using tablets in the classroom could reduce the time it takes for them to complete tasks. Additionally, there are endless tablet functions(功能)which could provide interesting teaching a4.. For example, we could play computer games to teach Maths, or make simple flashes to show how magnets behave. Also, students could take photos outdoors and then use them for writing tasks.

However, we must also consider the possible problems with introducing tablets to our classrooms. Some students may play with the tablets instead of f 5. on their work. Another problem is that, while many students can use tablets already, many of our teachers are not good at it and would need to be trained. We may also have problems with the tablets breaking, which would be very expensive to r6. . This is in addition to the cost of buying the tablets in the first place.

All in all, even though using tablets in the classroom may have many problems, it seems that it would be a wonderful opportunity for students and teachers at our school. There are a lot of costs indeed, but it would c7.prove to be a worthwhile investment(物有所值的投资).
