Thanks to new technology, going to school these days can be a pleasant experience. No longer having to rely on 'chalk and talk', teachers can give pupils the opportunity to play a more active role in their own learning. This makes learning a more individual experience and students with different learning styles can take in knowledge more easily. This can motivate students (1).

Nowadays students can learn individually or in groups to improve their skills. Using technology is said to develop students' critical thinking, cooperative learning (2).

Students can also learn at their own pace with the use of computers.

However, not all schools are taking full advantage of these opportunities. Sometimes schools cannot afford to buy the equipment (3).

In other cases, schools have the resources (4). Schools need to decide which types of technology can improve teaching to make learning (5).

In addition, teachers need to become familiar with new products, software and on-line resources (6). Only

in this way will schools be able to function effectively in the future

A but lack clear goals

B more attractive and valuable to students

C and communication skills

D and discuss them with their colleagues

E or teachers are insufficiently trained to use it in their classes

F although it makes them feel more comfortable using technology

G especially as most students enjoy using computers
