What phase of lesson delivery focuses on identifying and teaching main concepts for mastery?

In the context of lesson delivery, the input phase is crucial for laying the foundation of understanding and mastery of main concepts. This phase involves presenting new information and key ideas to students, ensuring they grasp the core content that will be important for their learning progression. During the input phase, educators use various instructional methods, such as direct teaching, demonstrations, or multimedia presentations, to engage students and help them develop a strong grasp of the subject matter.

Focusing on the main concepts allows students to build upon their existing knowledge and skills, which is essential for effective learning. Mastery of these concepts sets the stage for deeper understanding and application in later phases of learning, such as practice and assessment. The purpose of the input phase is to ensure that students are equipped with the necessary information and understanding before they move on to applying or evaluating that knowledge.
