What is a key characteristic of the curriculum design for adult learners?

A key characteristic of the curriculum design for adult learners is the focus on application of a single concept. Adult learners typically bring a wealth of experiences to the classroom, and effective educational approaches build upon these experiences. This learning model emphasizes practical relevance and the application of knowledge to real-world situations, rather than mere rote memorization or passive learning.

By concentrating on a specific concept and its application, the curriculum can directly address the needs and interests of adult learners, facilitating deeper understanding and retention. This approach encourages critical thinking and problem-solving, which are essential skills in adult education.

In contrast, the other choices do not align with the principles that are effective for adult learners. For example, focusing on passive learning techniques does not engage adult learners who benefit from active participation. Similarly, group memorization doesn't leverage the experiential background of adults, and strict adherence to a set schedule can be restrictive, as adult learners often have varying commitments and need flexibility in their learning processes.
