A Possible Research Topic

As the mobile learning is become more and more popular in modern education, students are able to grab a piece of information so quickly through their iPhone/iPad or any other Internet-connected digital devises, do they still bother to make efforts to remember something?
At “ancient times”, we used pens and paper notebooks to record what teachers were taught in classes, when writing took place, to some extent, it helped students to take the first step in remembering the contents; when they reviews the class, things written on notebook could remind the learning contents again and they may think more deeper, then they might add more notes on. It’s better to understand the whole thing and remember what you have learned now, otherwise, it would be a huge task before the exam when you basically need to start from zero.
According to cognitive theory, two things are very important:
(1) The memory system is an active organized processor of information and
(2) Prior knowledge plays an important role in learning.
If students are so easy to get the information from Internet through their mobile devices, they may feel there is not a necessity to remember everything, since their mobiles made it possible for information-on-demand (or knowledge-on-demand). However, one’s knowledge is expended based on what they have now (what they remember), if you don’t have the previous knowledge base, you cannot absorb new knowledge. It can be explained that why we have prerequisites for different courses.
So what I feel will be an interesting research topic is that “Will the use of Internet – connected mobile devices weaken the memory ability for students?”
To conduct a research, a comparative experiment can be conducted. For one group of students, they are allowed to use iPhone/iPad during the class, and for the other group, they can only use pens and paper during the class. We can ask them to have a quiz right after class to see what happen to their short-term memory, and of course, we can also wait until the end of semester to see which group did better job in the exam.
Still, I think the result might be different when conduct experiment in primary school, secondary school and in the university. But I may have the hypothesis that it matters more in primary level.
