The Guided Discovery Principle in multimedia learning refers to a teaching approach that combines the use of multimedia materials with guidance and scaffolding to help learners actively discover and construct their knowledge. It is based on the theory of constructivism, which suggests that individuals actively build their understanding of the world through interactions with their environment.
Guidance is an essential component of the guided discovery principle. Educators or instructional designers provide support and structure to help learners navigate the learning materials effectively. For example; learners are provided with multimedia resources such as videos, interactive simulations, or online modules that present information or demonstrate concepts.

The Worked-Out Example Principle in multimedia learning is a cognitive learning strategy that involves presenting learners with a step-by-step solution or demonstration of a problem-solving task. It is based on the idea that learners can effectively learn by studying fully worked-out examples that provide explicit guidance on how to solve a problem.
