What is the difference between curriculum teaching and instruction?

A Simple Answer The curriculum is the "what" that is to be taught. Curriculum is designed by state boards of education and education stakeholders, it is influenced by policies, mandates, and legislation. Instruction is the "how" and the "way" that the curriculum is taught. A teacher can deliver instruction in ways that make it approachable by all students, including those with disabilities, by making it accessible, called differentiated instruction. Teaching is the personal skills and professional preparation demonstrated by the "who" in the equation, the teacher. The teacher uses the curriculum to design the instruction that, hopefully, causes students to learn. Sometimes it is the other way around.
