Adults enjoy applying what they learn to the real world. It is not always obvious how a math problem pertains to the real world beyond simple arithmetic. For this reason, it is important explain how a particular math problem can be related to a real-life experience. An example with money might involve calculating how much simple interest can be earned over time using algebra.
Learning speed tends to decrease as a person gets older. However, the depth and scope of learning increases as adults grasp subjects on a more relevant level than children. Educators can accommodate adult learners by introducing new mathematical concepts one at a time and in a slow, thorough manner. Confusion and frustration can be avoided by making sure every student fully grasps the subject at hand before moving on to a new topic.
Adults enjoy knowing why they are learning something and are less likely than children to accept information they feel is irrelevant. Teachers can accommodate adults by outlining lesson plans and explaining what they expect each student will have learned by the end of the lesson. Doing this adds perspective to adult learners and may help them understand subjects faster. Goals also provide a sense of motivation and satisfaction when they are met.
Whereas children may be disciplined and treated authoritatively, adults should be treated as equals. Educators should think of adult students as peers who have requested help on a particular topic. A math problem that seems obvious to one person may be bewildering to another. Feelings of guilt and shame can be eliminated by treating everyone with equal respect. Reassure adult learners that there are no "stupid questions."
