That being said, there is one way to cheat twitter's adhd inducing characteristics that can make it a useful tool for educators and other professionals; provided they have a smartphone... Tweets can be tracked, (as mentioned in the "28 Creative Ways Teachers are Using Twitter" article, 28 Creative Ways teachers are using Twitter) to discover trends and to see students' and other teachers' progress and findings.
Other than this, however, the rest of the article seems to suggest classroom-disrupting and distracting behaviors for the 21st century student. I hope I am not hurting anyone's feelings by taking this stance, but tweeting the answers to questions in the middle of class seems to be detrimental to the learning process. I feel that if the teacher and students are meeting in a classroom on a regular basis, it stands to reason that the students ought to be expected to raise their hands to answer a question posed. Also, God forbid a student should have to use a pen and paper to take a quiz or test.
I understand that Twitter can be helpful for someone with enough technology on-hand to look like an 80's action movie villain, but for most people, especially in the ESL field, money isn't the most plentiful thing in life, and twitter may be a bit unreasonable for the classroom. That being said, the opportunity for the exchange of new ideas and classroom activities is endless, and for a teacher making a lesson plan, or seeking help on how to reach a struggling pupil, Twitter may just provide you with some quick answers.
