Thank you all for your amazing ideas in the comments on my first reflection.
There are some more ideas I would like to share with you about my project.
The second theme I see in my research about the blog reflection is about self identity and personal meanings. I wonder what does the blogs mean to them. Do they feel positive or negative about it? How they understand the identity issues in their posts? By analyzing all the data, I believe there are both positive and negative feelings among students about this issue. Some students report that they find their own voice in the post. As student A said, she was very shy, and it is still hard for her to share her ideas with a group of people openly. The blog serves as a great platform for her to overcome her shyness and express her thought. She feels that although she missed many posts, she owns each of the pieces she had there. Therefore, she does construct personal meaning for herself through the blog. However, some others feel differently. Some students, such as student O, were explicit about their carelessness about the blog. When hearing "it is not me", or "I don't remember what I have wrote about", I feel that the blog is not part of the student's identity and has no meaning for them. They are not really devoting to it and owning their work, but checking boxes for others. I feel the same way when student R said that he wrote in "professional voice" in the blog. The so-called "professional voice" is also what I have observed in their posts. In some posts, students are not talking about their own experience. There is no "I" in their post. It is more objective than subjective. The authors' feeling are alienated from the posts.
I am not sure how to evaluate this phenomenon, since it leads the discussion back to the purpose of the blog. If the goal is to let students think about their daily life and reflect on their learning experience, then "I" should be invited in their posts and their writing should be part of their identity. However, if the blog is expected to be a space where students ponder about general questions and practice academic writing, then the objectivity should be appreciated. When having these two situations, I cannot help asking myself who has the right to decide the purpose of the blog. If the instructor has the power, will it still be "learner-centered" education? If the students does, are they mature enough at this point to make the best decision for themselves? Or, as raised by Joyce, should the college also teach students to deal with tasks they have to do although they may not like it? I just keep posing questions, but cannot find the perfect solutions to them.
Also, when responding to others, students tend to be sweet smiling faces instead of challenging questioners, especially, as Student R mentioned, after two students had a conflict about the way of challenging others' ideas. Responding in writing language is the primary way for students to comment on each other's posts. They are expected to be thoughtful and respectful in their comments. Here comes the questions about the differences between personal and public speech, as well as writing and oral language. As instructors, we did start the conversations and prepare students well for the task until the conflicts happened. Due to the lack of relavant skills, students get worried about their social relationships and decide to shut their changeling ideas down. Therefore, when do it next time, we may think about what we need to do to prepare student better for the tasks they are assigned with. Also, student may get irritated when reading others comments because they misunderstand their tone or intention. Accordingly, it may be helpful to spare some class time to discuss about what is going on in the blog. By having face-to-face communication, students may understand each other better, and become genuin curious about others' ideas.
Honestly, I didn't expect to find such a rich body of information and to learn so much. At this point, I am really glad to that I did this, which gives me many ideas about what to do when I have my own class. Also, thank you, my dear professor and classmate, for your constant encouragement :)
