Which of the following characteristics must an instructional objective include regarding the audience?

An instructional objective must clearly state the specific audience for the educational activity, which ensures that the objectives are tailored to the needs and characteristics of the learners. Identifying the audience allows educators to design instruction that is relevant and appropriate for that group, taking into consideration their prior knowledge, learning styles, and developmental levels. This alignment enhances the effectiveness of teaching and learning by making sure that the content and methods used are suitable for the intended learners.

In contrast, including behavior that is not observable undermines the clarity and measurability of the objectives. Objectives should focus on observable actions that can be assessed. Describing teaching methods used or focusing solely on instructional materials are not necessary components of an objective, as they do not specify the audience's characteristics or articulate what the learners will achieve. Instead, a well-crafted objective centers on the learner's attainment and the outcomes expected from them within the educational setting.
