The key elements of teaching and learning are the teacher, learner, and learning environment. The teacher guides the educational process, while learners are the participants in learning and differ in abilities, aptitudes, interests, backgrounds, and attitudes. A conducive environment provides necessary features to link these elements and guide methodologies. Learners are equipped with cognitive and appetitive faculties like senses, intellect, emotions and will. However, these are expressed differently depending on one's abilities, aptitudes, interests, values, attitudes and family background. Learning styles also vary between mastery, understanding, self-expressive, and interpersonal styles.
