Introduction Brain-based learning is becoming popular since it provides a good framework that helps to raise students’ performance. Brain–based learning provides an opportunity for the students to link their prior knowledge with the current content area learning; hence, it facilitates learning process for every student (Jensen & Jensen, 2008). The purpose of this paper is to discuss the fundamentals of the brain based learning, and the brain dominance. It will shed light on how a classroom teacher can optimize students’ learning. Fundamentals of Brain-Based Learning The Concept of How a Student’s Brain Learns Jensen & Jensen (2008) affirms that learning process of the brains depends on the emotions of the child since the power of cognition has a correlation with emotions. Emotions affects the learning process since the student under threats releases some chemicals in the brain that inhibits understanding of content. A teacher should therefore pay close attention to students with physical disabilities since these students have high chances of developing negative emotions that may result from peer rejection. This can be achieved by teaching social behavior publicly as it enhances social acceptance through emphasizing on the importance of diversity in classrooms. Through this acceptance, children with physical disabilities will demonstrate positive emotions that facilitate content area learning. The teacher should also note that there are students who have learning disabilities that are neurological in origin, hence affected in understanding the content of new concepts (Jensen & Jensen, 2008). These students demonstrate a problem in processing new information. It is therefore paramount to be flexible during teaching since the neural connection is responsible for stimulating the appropriate learning style, which is experienced when current passes along the nerve cells in the brain. Jensen & Jensen (2008) affirms that introducing of new concepts can be enhanced by accommodating prior knowledge of these students. For example, teaching students that the world is round can be introduced by accommodation the notion of students who believes that the world is flat, and then coming up with information that will help them to analyze and criticize their prior concepts. The teacher can also ask the students to compare the previous leadership with the current leadership style. Creating this link helps the students to understand the concepts of new content. Another example involves the use of body movement in order to enhance understanding of language such as standing up and sitting down to demonstrate the difference between consonants and vowels (Willingham, 2004). Brain Dominance The Paradox of the Left Side Processes and the Right Side Processes of the Brain There are diverse ways of enhancing brain dominance during the learning process. One of these ways is enhancing memory. This results from the fact that brain comprises of several parts, which are used to store different types of memories. For example, while listening to the music the brain can store the composition of the music separately. In this case, the melody of the song can be stored in a different part of the brain from the lyrics of the song (J
