I believe that a twitter discussion is more effective than a blackboard discussion and an in-class discussion because of the fact that it is a socializing website and now a day, more people are into technology. By using twitter discussions, students that are usually quiet in class can even have their voices heard. It makes participating in class discussions less intimidating. I believe twitter can enhance discussions and can bring more student interaction than in-class discussions. Even in small or medium size classes, only a small number of students actively participate in class discussions. If people started using twitter instead, more will be heard and everyone would be participating since people can go on twitter using their tablets, cell phones, or any type of technology.
A blackboard discussion may not be as effective as a twitter discussion but is definitely way more effective than in-class discussion. Just like twitter discussions, more people participate and respond to others than in the classroom. The differences between this and twitter is that only colleagues that belong in the specific class can respond to your responses or comments. You can think of it as a virtual version of the classroom. It is also more of an educational environment because in twitter, other strangers are able to respond to your comments.
An in-class discussion is the least effective because students don’t participate as much as they are supposed to do. Let’s be honest, there are only those certain people who always raise their hands while the others are either sleeping, not in class, or just doing something else. Overall, discussions using technology is way more effective.
