Systematic instruction in reading ensures that lessons build upon what?

Systematic instruction in reading is designed to facilitate a coherent and progressive learning experience for students. By building upon previously taught information, this approach ensures that new lessons are connected to what students have already learned, which reinforces their understanding and retention of reading skills.

When instruction is systematic, it follows a structured sequence that enhances skill acquisition. For example, if students first learn phonemic awareness, the next lessons can introduce phonics, using their existing knowledge to tackle reading more complex words and texts. This cumulative build-up of skills is important for developing a robust literacy foundation, enabling students to confidently engage with increasingly challenging material.

In contrast, random information, unrelated concepts, or vague anecdotes do not provide a solid framework for learning, as they lack the necessary connections to prior knowledge that help facilitate comprehension and skill mastery. Thus, building on previously taught information is essential for effective reading instruction.
