山东省泰安市东平高中2021届高三上学期英语第一次月考试卷
Each post on Twitter or Tweet to this online social network can run no more than 140 characters. Explaining a scientific concept in only 140 characters can be almost impossible.
Ryan Becker teaches physical science. He didn't discover Twitter until 2011, when he attended a technology conference with a session on using the network to connect with other teachers. “I knew nothing about Twitter or Facebook,” he recalls. “But the description sounded interesting.”
Becker soon realized that he didn't want to limit Twitter to teachers interacting with other educators. “I thought, 'Why can't kids realize all of these uses? '” And to find out, he began including Twitter into his classes.
Becker's school provides all of its students with netbooks. Becker let the kids set up Twitter accounts. For kids who do get accounts, Becker makes sure those accounts are protected. By that he means each student has to approve all followers, and his or her tweets will not be visible to people outside that protected-follower list.
Once his class had signed up, Becker had them Tweet during class time. He used Twitter himself to share science videos and articles with his students as he ran across them—things he might not have had time to load and share during class periods.
“One of my big reasons for using Twitter is that I try to get students to connect science to their own lives.” he says.
Becker stresses that his use of Twitter is only in the classroom. “Usually if I'm asking them to use it. I'm giving them time in class,” he notes. “It's not meant to supplant (代替) classroom learning. It's meant to complement and extend it. ”
But teachers will need to be careful that the students who use Twitter in class don't have their horizons expanded too broadly, says DeRosier. If inappropriate things end up filling students' feeds, the teachers may pay the price, she warns, because “When things go wrong on the Internet, they go catastrophically wrong.” She recalls the case of a high school teacher who was being filmed using Twitter with his class.
