Roles of CALL

The class on the roles of CALL makes me realize on actually there are many roles of the computer. One thing for sure, the process of teaching and learning that is assisted by computer will definitely makes it more fun and meaningful. However, do the school especially the teachers use computer in their lesson? Reality check people..Not all schools are equipped with this facility..That is a actually a waste because pity those who are living in rural areas because they might not get the exposure..Hence it is still a question mark on the effectiveness of the use of computers in teaching and learning process..
