Which type of instruction focuses on a logical sequence from simple to complex concepts?

The type of instruction that emphasizes a logical sequence from simple to complex concepts is systematic instruction. This approach ensures that educators introduce foundational skills and knowledge first, enabling students to build on these essentials as they progress to more intricate ideas. By following a structured path, systematic instruction promotes a clear understanding and retention of the material, allowing learners to connect newly acquired information to prior knowledge. This is particularly important in multi-sensory structured language education, where the clarity of instructional progression can significantly impact student learning outcomes.

Cumulative instruction, while also building on previously learned concepts, may not always represent a strict sequence from simple to complex, and it can vary based on the specific skills being taught. Randomized instruction disrupts this ordered flow, leading to potential confusion and gaps in learning. Flexible instruction, on the other hand, accommodates individual learner needs but does not necessarily adhere to a standardized order of complexity, which makes it distinct from the systematic approach.
