Principles that should be applied in the classroom or business meeting

One of the principles that I think is very effective is the Signalling principle. By applying Signalling principles, it helps students to focus on the most important part of the material that the teacher presented in class. The highlighted content will draw more attention from the learners so that they can memorize the important knowledge easier. Another one is the Animation principle. When doing a PowerPoint presentation, the animation helps a lot for the transition of different materials or topics to encourage people to distinguish the differences.

Principles I have ignored and Principles I have followed along.

Ignored principles:  Segmenting principle, Modality principle, Worked examples principle and Feedback principle.

Followed principles: Multimedia principle, Redundancy principle and Temporal Contiguity Principle.
