Teachers, online communities, and its negativity atmosphere

Community of Practice, Affinity spaces, Personal Learning Networks, Personal Learning Environments

Pros: Teachers can seek advice and even share their thoughts on educational practices. The online spaces can help teachers feel a sense of belonging.

However, I found that the atmosphere of a teachers' online community is filled with negativity atmosphere. Users (most of them are teachers) are sharing ideas and thoughts by asking questions or posting their experiences. However, there are too many negative postings. Why?

• I recently accepted a job teaching high school woodshop class and am doing a transition to teaching program. I've been excited to shift my career but am worried about all the negativity in the teaching field. Is it all that bad? I read so many posts here that describe how terrible the profession is. What are some positive aspects of the field?

• I graduate with my masters next month and I accepted a position teaching a freshman level class at the same university next semester. Depending on how much I like it, I may make teaching a career. I don't expect to get my doctorate and keep teaching at the college level. So I would eventually go to K-12. But is it really as bad as yall make it out to be? This sub is very negative and I was wondering does this reflect reality or is this more of a place to just let off steam? Is the negativity of this sub the average experience for K-12 teachers?
