I would not say that one is better than the other. It is just that we use them with different purposes. Both of them are web 2.0 tools that aim at promoting collaboration on the web. These tools offer the possibilities to easily share ideas or experiences to the world. In my experience, blogs are more unidirectional than wikis.

Short video lectures are viewed by students at home before the class session, while in-class time is devoted to exercises, projects, or discussions.

I listened to lectures before the class on my own pace and could even start doing homework while listening. I really enjoyed that. Also coming to classes and having to work on posters in groups was engaging and very motivating. I wish we could do more of that. I found it more meaningful, a
