How do we learn? What makes us smart and how do we remember what we have learned, what can I do to motivate myself and others, what makes us do the things we do? These are all questions that a student teacher needs to have answered in order to be able to teach effectively. Following are some explanations that have guided my understanding of how I have learned and how I can become more effective in my teaching practice.
The brain is a good place to start when we talk about learning. “It is sometimes referred to as a muscle of thinking.” (Biology about.com)There are lots of different parts to the brain, but the forebrain, midbrain and hindbrain are the biggest parts of the brain. There are billions of nerve cells starting to form, from when we are born. Cells or (neurons) receive messages through what is called a dendrite, which I envision to look like the crown of a tree in winter. These messages get passed through the Axon, I envision these to look like the trunk of a tree), and then across a gap called a synapse, which is the gap in between two dendrites. These messages transmit from one cell to another, via a chemical neurotransmitter. To improve the speed of the connecting messages, a process called myelination occurs; this is a fatty casing surrounding the axon in order to speed up the process of connections of the brain. The neurons start to develop and form more and more connections, as the child get’s introduced to different experiences. Some of the connections that are not used in time will be severed. There are aspects that affect brain development, such as good nutrition, genetics and experiences the person has been exposed to. Different parts of the brain develop at different times .When a child reaches a certain milestone we can be sure that the brain has again formed a large amount of neurons in the appropriate part of the brain. The area that controls language (forebrain) shows most development in infancy and early childhood, when children are starting to gain more and more language (Krause,2010).In my years of working as a child care worker I have observed that, some children of the same age seemed to arrive at different developmental stages at different times. For example one child aged twelve months , could walk and move around obstacles with ease, her language was average for a child of her age ,yet another child of the same age was only able to sit on her bottom, did not attempt to walk or even crawl, but her language was outstanding. The brain is such a complex organ, I have learned the basic structure of the brain, and am able to better understand why some children in childcare were able to do things, others could not. It seems childhood is a crucial time for children and brain development, even though genetics play a great part in the way our brain is structured, a healthy diet, plenty of sleep and a good variety of experiences all play a part in the way our brain develops from early...
