Which method of arranging lesson material progresses from simple to complex?

The method of arranging lesson material that progresses from simple to complex is known as progressive arrangement. This approach is based on the principle of scaffolding, where learners are provided with foundational knowledge and skills before advancing to more complex concepts. By starting with simpler ideas, instructors can ensure that students build a solid understanding, which helps facilitate the learning of more challenging material later on. This method is particularly effective in educational settings because it helps to reduce cognitive overload, allowing students to gain confidence as they progress through increasingly complex topics.

In contrast, the other arrangement methods mentioned have different focuses or structures that do not specifically emphasize moving from simple to more complex ideas. For example, chronological arrangement organizes material based on time or sequence, topical arrangement groups concepts by subject matter, and circular arrangement might involve looping back to earlier topics rather than escalating in complexity. Thus, progressive arrangement is distinct and particularly suited for promoting understanding.
