Problem solving is one of interesting subject in this first semester of my course. Actually, I still curious why most of people prefer avoiding a problem including me. And to be honest, I just realise that at first time we face problem, directly we will think to solve it. So that the problem will be so difficult. But, in this course, we learn about how we understand the problem first. After understanding the problem, we can try to solve it. As a result, we will be happy and satisfy when we face problem and we can solve it easily. Furthermore, the materials or articles correlated to Problem Solving can be learned here.
