Learning and Teaching in the 21st Century as PLE

To my mind, the lesson Learning and Teaching in the 21st Century that we are studying online recently is one of the best example of Personal Learning Environment (PLE from now on) judging from my experiences. Actually, there are many reasons why it is an example of PLE.
One of the very first one is the fact that we have the control of our learning and we can manage our learning. That is, I can look for the topics, which are getting more and more each day, that I'm interested in the website and blogs and pick the one I like and in this way direct my learning process.
Another important point that makes our recent learning environment a real PLE is that our website is not processing on it's own, but integrated with some other Web 2.0 technologies like blogs and forums. In this way, we can express and share our thoughts and findings with our colleagues while they also can do the same thing and we can mix our ideas and find the exact information we are looking for. In fact, with the beginning of using the forum, we have a more flexible and convenient Web 2.0 tool and it has became much easier to create a discussion environment to exchange ideas and collaborate.
As well as these, when using, sharing and trying to get the information, learning becomes more learner centered and we create and control our own knowledge that we need and we are interested in, which is the the main characteristic feature in the process of PLE phenomenon.
Lastly, thanks to Web 2.0, which also consists our website, blogs and forum, we can add, modify, change, share, collaborate, upload, download and post our ideas and impressions about a topic. In simple words, we create and form what we learn and this is what makes PLE which is not a learning system, but a learning environment.
