Why is it important for lessons to build on previously taught information?

Building lessons on previously taught information is essential because it facilitates comprehension from simple to complex concepts. When instruction progressively introduces new information that connects to the learners' prior knowledge, students can better understand and retain the material. This scaffolding approach helps bridge the gap between what students already know and what they are expected to learn next, allowing for a more coherent and integrated learning experience.

For example, in reading instruction, a teacher might first ensure that students have a solid understanding of basic phonics before moving on to more complex comprehension strategies. This logical sequence not only aids in retention but also boosts students' confidence as they see their ability to grasp increasingly challenging material.

The other options do not align with the core principle of building on prior knowledge. Creating a challenging environment, for instance, might lead to frustration if students are not adequately prepared for the complexity of new concepts. A disjointed learning experience would hinder engagement and understanding since students would struggle to make connections between lessons. Independent study, while valuable, is not the primary goal of building upon prior knowledge; rather, it is the foundation necessary for successful learning in collaborative settings and structured environments.
