In curriculum development, which approach emphasizes the integration of…

Concept: A curriculum approach is identified by its organising centre — the thing around which content is arranged. When separate academic disciplines are that centre, every subject keeps its own boundary, syllabus and sequence. When a theme, problem or real-life issue is that centre, content is deliberately drawn from two or more disciplines at once, so the learner meets the topic as a single whole instead of as unrelated periods. Other terms in this field answer a different question altogether: a learning theory describes how learning is engineered, while an unplanned influence describes what is picked up without being taught.

Application: The stem supplies two markers — integration of various subjects, and addressing social issues so that understanding is holistic. Both point to an organising centre that is an issue rather than a discipline: the content of several subjects is pulled towards one social problem. That is exactly what the interdisciplinary approach does. A theme such as water scarcity is taken up through science (the water cycle), geography (rainfall and rivers), economics (cost and distribution) and language (reporting and persuasion) at the same time, with the subject boundaries deliberately crossed so the concepts of one subject are used inside another.

Cross-check: Testing the other approaches against the same two markers separates them clearly.

• Subject-centered approach — arranges the curriculum as discrete subjects with their own periods and logical order; the disciplines are kept apart, so integration across them is not its design.

• Hidden curriculum — the unplanned values, norms and habits absorbed from school routines and relationships; it names an unintended influence on learners, not a way of organising subject content.

• Behaviorist approach — builds learning through measurable objectives, stimulus-response practice and reinforcement; it prescribes how content is delivered and tested, not how subjects are combined.

Conclusion: The approach that integrates various subjects around social issues to foster holistic understanding is the interdisciplinary approach. (A related term worth keeping distinct: a multidisciplinary design places each subject's view of the theme side by side, whereas an interdisciplinary design merges their concepts and methods into a single enquiry.)
