The multimedia principle is a widely studied and supported theory that suggests that learners can benefit from the use of multiple modes of representation in learning materials, such as text, images, and audio.

The principles of multimedia learning are applicable to virtual immersive environments (VIEs), as these environments often rely on the use of multimedia elements to provide learners with a rich and dynamic learning experience. In this section, we will explore each of the principles of multimedia learning and how they can be applied in VIEs (Rudolph, 2017):

Multimedia principle: In VIEs, the use of multimedia elements such as videos, images, and animations can help learners better understand complex concepts and processes. For example, a VIE that teaches about the solar system can incorporate images and animations of the planets and their movements to provide a more engaging and memorable learning experience.

Coherence principle: In VIEs, it is important to organize the multimedia elements in a meaningful and logical way to avoid overwhelming learners with too much information. By structuring the learning materials into clear and concise segments, learners can better understand the connections between the various elements and how they relate to the learning objectives.

Contiguity principle: In VIEs, it is important to present corresponding words and images near each other in time and space. For example, in a VIE that teaches about the human body, images of organs and their functions can be presented alongside written descriptions of their roles to enhance understanding and memory retention.

Modality principle: In VIEs, using multiple modes of representation, such as animations and narration, can help learners better understand complex concepts. For example, a VIE that teaches about the structure and function of a cell can incorporate 3D animations and narration to provide learners with a more immersive and engaging learning experience.

Redundancy principle: In VIEs, it is important to avoid including redundant information, such as repeating information already presented in other forms. This can help to reduce cognitive load and avoid overwhelming learners with too much information.

Personalization principle: In VIEs, using a conversational style of language can help learners better engage with the learning materials and feel more connected to the content. For example, a VIE that teaches a language can incorporate conversations and interactive dialogues to help learners develop their speaking and listening skills.

Segmenting principle: In VIEs, breaking up the learning materials into shorter segments can help learners better engage with the content and avoid feeling overwhelmed by the amount of information presented.

Pre-training principle: In VIEs, providing learners with an overview of the key concepts and ideas before diving into the learning materials can help to prepare learners better and increase their engagement with the content.

Guided discovery principle: In VIEs, providing learners with opportunities to explore and discover concepts on their own can help to promote deeper understanding and critical thinking. For example, a VIE that teaches about history can incorporate interactive scenarios that allow learners to explore and understand historical events and their significance.

Practice principle: In VIEs, providing learners with opportunities for practice and feedback can help to reinforce learning and increase the retention of new information. For example, a VIE that teaches math can incorporate interactive exercises that allow learners to practice and receive feedback on their progress.

Numerous studies have shown that using multiple modes of representation in learning materials can enhance learning outcomes, particularly in terms of memory retention and problem-solving abilities. The multimedia principle is particularly relevant in VIEs, which offer a rich and dynamic environment that can include a wide range of sensory stimuli. Studies have demonstrated that using multimedia elements such as graphics, animations, and videos in VIEs can improve learning outcomes, particularly when the multimedia elements are closely aligned with the learning objectives (Wright, 2014).

However, the effectiveness of the multimedia principle in VIEs depends on various factors. One of the most important factors is the level of interactivity in the VIE. Interactive elements, such as simulations and games, can be particularly effective in engaging learners and promoting active learning (Mayer & Moreno, 2003). Studies have also shown that the use of interactive multimedia elements in VIEs can improve learning outcomes, particularly in terms of knowledge retention and transfer (Rieber, 2005).

Another important factor that can influence the effectiveness of the multimedia principle in VIEs is the level of cognitive load. Research has shown that multimedia elements can increase cognitive load, particularly if the elements are irrelevant to the learning objectives or too complex (Sweller et al., 2020).

According to Buchner et al. (2022), VIE designers can reduce cognitive load by using methods such as minimizing extraneous cognitive load, segmenting and organizing information, and emphasizing essential information. For example, reducing the number of distractions in the virtual environment, such as irrelevant visual and auditory stimuli, can help learners focus on essential information. Similarly, segmenting and organizing information can help learners better process and retain the information presented in the VIE. Designers can also emphasize essential information through highlighting, repetition, and summarization, which can help learners recognize important concepts and better integrate them into their existing knowledge structures. These techniques can help learners engage more effectively with the learning content and improve learning outcomes.

Therefore, it is important to consider the design and use of multimedia elements in VIEs to avoid overwhelming learners with too much information.
