　　New opinion studies have found a majority of teachers believe technology is helping them do a better job in the classroom. But the research also shows that many educators are concerned digital devices（设备） can cause physical and mental harm to students. While overall feelings about technology were good among college educators, an increasing number said technology could also be harmful. A total of 19 percent of those questioned said they felt technology had made their job harder or much harder. The study also looked at how technology helped teaching effectiveness（有效性）. A large majority of educators, 87 percent, said technology had positively affected their ability to teach. Eleven percent said they felt technology had no effect on the quality of their teaching. Just two percent said technology had a negative effect on teaching. Results of the survey also found teachers had good feelings about technology's effects on learning. Eighty-three percent said they felt technology had positively affected their students' learning. Just nine percent said technology did not affect student learning, while eight percent said they believed it had a negative effect. Some teachers had expressed mixed feelings about the use of technology. One noted that the learning process can suffer if students depend too much on their devices. "People can easily get addicted（上瘾的） to their devices, and using technology can change the way the brain develops - not always in a good way," the teacher wrote. Parents were mostly more supportive（支持的） than teachers of digital devices and their effects on school-age children. 87 percent of parents believe such devices are mostly helpful, while 13 percent said they are mostly hurtful.
