It's a dynamic and often unpredictable process influenced by numerous factors including:
* Teacher's beliefs and pedagogical approaches: A teacher's philosophy on teaching and learning significantly impacts how they deliver the curriculum.
* Student characteristics: The diverse learning styles, abilities, and backgrounds of students necessitate adjustments to the planned curriculum.
* Classroom context: The classroom environment, available resources, and school culture all shape what happens in practice.
* Unforeseen events: Unexpected disruptions or opportunities can lead to deviations from the intended plan.
* Time constraints: Limited time often forces teachers to prioritize certain aspects of the curriculum over others.
Understanding curriculum-in-use is crucial for evaluating the effectiveness of a curriculum and for improving teaching and learning. Researchers often observe classrooms to analyze curriculum-in-use and identify areas where the intended curriculum is not being effectively implemented or where adjustments might be necessary. It's a valuable tool for professional development and curriculum revision.
