Preparing illustration or diagram displays in advance saves:

Preparing illustrations or diagram displays in advance saves class time by allowing the instructor to focus on the delivery of content rather than spending valuable instructional minutes creating visuals during the lesson. When instructional materials, such as diagrams or illustrations, are prepared ahead of time, they can be easily referenced, allowing for smoother transitions between topics and a more engaging learning experience. This proactive approach enhances the efficiency of the educational session, enabling the instructor to address questions, facilitate discussions, and ensure that the class stays on schedule without interruption. While there may be benefits in terms of effort, money, or materials, the primary advantage directly affecting the educational experience in this context is the preservation of class time.
