As we know, everything has a positive and a negative use these days because you don't have control over the things people do. Same thing goes for the use of technology in classrooms. If you use it for good purpose like presentation and lab experiments, it is really good for learning but if you use it for other purposes like chatting on smartphones during class and other restricted uses, it is really bad. So we can say that it is similar to any other aspect these days and we can totally describe whether it is a good thing or not.
