There are many different views on how people learn or what method helps students retain information best. One view is described as asking questions and making connections. Carl Sagan said, “There is no such thing as a dumb question.” If asking a particular question, whether you think it is worth asking, helps you understand a concept, then the question should be asked. Think about an expert in a particular field or one of your college professors; they have been studying and expanding their knowledge in that field for years. As a person learns new information and expands their comprehension of it by asking questions, it allows them to create and build connections with previously learned information. As these connections are multiplied and solidified, their knowledge base will grow, and their level of understanding will increase.
You should ask questions until you understand what is being taught or what you are trying to learn.
Another popular view on learning is characterized as “use it or lose it.” The idea behind “use it or lose it” is that repetition is vital. When new information is presented, find ways to use and reuse that information to help it make a permanent impression in your mind. Keep in mind the idea of “practice makes perfect.” The more you practice, recite, rehearse, and drill the content into your brain, the deeper that impression will be formed. Some examples of this learning view in practice would be learning multiplication tables or playing scales on an instrument. The more you repeat these actions, the more they become ingrained in your brain.
