What instructional strategy is being utilized when a teacher develops a unit that blends various subjects?

The chosen answer is correct because interdisciplinary instruction specifically involves integrating knowledge and skills from multiple subject areas into a cohesive learning experience. This instructional strategy encourages students to make connections between different disciplines, understanding how they interrelate and contribute to a more holistic grasp of the concepts being studied. For example, a unit on climate change could involve science (understanding the science behind climate change), social studies (impact on communities), and math (analyzing data trends), allowing students to see the topic from various perspectives and reinforcing learning across subjects.

In contrast, multidisciplinary teaching refers to the instruction of multiple subjects within a unit as separate components, where each subject is explored independently without integration. Independent instruction focuses on self-directed learning where students take initiative, which does not typically involve blending subjects. Extracurricular learning refers to activities outside the standard curriculum, such as clubs or sports, and does not encompass the blending of subjects in formal lesson planning.
