In this week lecture, we learn about learning theories. Learning theories are an organized set of principles explaining how individuals acquire, retain and recall knowledge. We can understand well on how learning occurs by studying learning theories because we as a future teacher that need to face various kind of students. There are four learning theories which are, behaviorism, cognitivism, connectivism and constructivism. Behaviorism reacts on a principles of "stimulus response" and the behavior caused by operant conditioning and it shaped through the positive and negative reinforcements. The learning process is based on objectively observable changes in behaviour. Other than that, cognitivism focuses on mental process. It shows how people perceive, think, remember, learn and solve problems. Next, Connectivism is actually a newest learning theory it is where people learn and grow by forming connections. Connectivism is a learning theory that explains how Internet technologies have created new opportunities for people to learn and share information across the world and among themselves. Last but not least was constructivism. Constructive theorists found that human beings are unique in their ability to construct unique understandings of their immediate environments and the world beyond them. Every individual experiences life differently based on an immeasurable number of physiological and emotional factors.
