In week 2, one of the ideas that learning through PLN can be a lifelong learning tool in our lives has raised my interest that I want to learn more about PLN. This is one of the Wows that I want to share with others. However, there are some questions that I have for this week as follows: I wonder why the author say only relying on things learned in school will not be enough to give skills and knowledge in the forever-changing world. What other knowledge is required for such a forever-changing world? What should people do to improve their own ability to adapt to such a forever-changing world?
