Situation in Class

My lecturer in class ask us whether we all have created a blog. She became angry and disappoint with some of the students because they haven't done it yet. She told us to do that about one month ago but still some of the students didn't do it. They are giving reasons that they do not know how to do a blog and they also don't know what to write. In my opinion, i think we can't get any knowledge easily, instead we must put in effort in order to learn something that we do not know. So, i really hope that students will be more hardworking when doing their works.
