It is necessary to have objectives always in the 3 domains?

Having objectives in the three domains—cognitive, affective, and psychomotor—is essential for a holistic approach to learning and development. Cognitive objectives focus on knowledge acquisition, affective objectives address attitudes and values, while psychomotor objectives relate to physical skills. Together, they ensure that learners not only understand concepts but also develop the necessary skills and attitudes to apply them effectively in real-world situations. This comprehensive framework enhances the overall educational experience and promotes well-rounded growth.
