Some people think textbooks are obsolete and should be replaced by Ipads.Don't you think that textbooks are valuable? I don't think replacing is true but we can mix replacing and stabilization and we can find a solution. In my opinion,in education system extreme technology using decreases the learning ability,because we are passing the practising process.However this process is cornerstone of learning.I don't want to cause misunderstanding.I support technology whose use is in learning.I only consider extreme level of it is dangerous.We should balance it.We should use classical techniques ,like textbooks, and technology same time.Namely replacing isn't permanent solution,it's temporary.When we use this solution we need help because we will encounter obstacles.You know breaking the routine takes time but it's not impossible. As a consequence you should try this solution because combining classical and technological techniques help you.
