A very interesting aspect of blogging was presented at the German teacher conference this year in Athens.
From what I understood, the project was divided into two kinds of blogs. Firstly, the students' blogs and secondly a summer-blog with excersises, texts and interesting stuff (links) for the students to read and do during the summer in order not to keep in touch with the language during the holidays.
The students' blogs is a very big project and needs lots of work and guidance by the teacher. In order for this project to work, most of it must be done in the classroom. This means that there has to be access to computers, which makes it really difficult for state school teachers or small language schools to go ahead with it.
Students are encouraged to work on their page layout, choose their subjects and write on their own without corrections by the teacher.
Teacher only gives them the tasks, which can be a text, a link, a picture or even a video.
Having experimented with blogging and students, I can only add that this work can only be a success, if the teacher steadily controls the students work and gives them input and feedback all the time.
On the other hand, can this be an obstacle in the creativity of the students?
I give you some links with the work of the students of Goethe Institut Athen and their teachers.
I must admitt that they worked really hard and with lots of enthusiasm...
