The main benefit of using technology in teaching is that it enables the teacher to present information in a variety of ways. The main disadvantage is that it is costly in set-up and maintenance, both in terms of time and money.
Teachers can use the internet to access information and help their students access it. Smartboards and document cameras allow teachers flexibility and the ability to adapt lessons on the spot in ways that chalkboards and overhead projects cannot. Handheld technology such as smartphones, touchscreens, and tablets allow students to interact with the teachers, and each other, in different ways.
The disadvantage of technology for student use is that teachers need to expend additional time and effort on tech-based classroom management. If students all have laptops, for example, teachers need to take time both to monitor use and to troubleshoot.
