Multimedia for Learning

What is Multimedia Learning?

Multimedia learning uses words, pictures, and sound. Mayer (2009) suggests combining visuals and audio, but avoid repeating content. This aids learner understanding and encourages them. Sweller (1988) and Paivio (1990) showed it improves knowledge retention.

Use multimedia to boost learner engagement. Combine visuals with text to aid learning. Integrate videos and images into lessons for better results. This guide offers strategies for all subjects and ages. Explore multimedia teaching, based on Mayer's work (2009) and research by Clark and Mayer (2016).

Teachers preparing online lessons need this concept. Knowing how to present material for screens is vital (Laurillard, 2002). This applies to all learners, children to adults (Conole, 2016; Bates, 2019).

Mayer's (2009) theory explains how learners use sight and hearing. Learners take in visuals like pictures and text. They process spoken words using their hearing. Too much information overwhelms learners (Sweller, 1988).

The pandemic changed learning quickly. Schools moved instruction online. Teachers adjusted methods for virtual sessions. Basic internet skills became essential (Hodges et al., 2020).

Teachers should know cognitive load theory when designing slides (Sweller, 1988). Textbooks can overwhelm learners (Mayer, 2009). Poorly designed slides hinder learning. Pictures, text, and sound impact information processing (Clark & Mayer, 2016). Teachers need multimedia learning skills (Mayer, 2005). This guide explains these ideas.

Mayer (2009) wrote about multimedia principles in *Multimedia Learning*. This book helps teachers make improved learning resources for learners. Teachers can use Mayer's (2009) ideas to enhance their lessons.

Mayer's Core Multimedia Learning Principles

1. Coherence Principle

Mayer (2009) showed learners learn better when we cut out extra content. Keep essential information when you teach. Remove interesting but unnecessary words and images from slides.

 2. Signalling Principle

Students learn better when the presented material with essential information is highlighted. For example, the teacher can use contrast and highlight colour, underline the text, or use arrows to point to the core of the message. Signaling helps the student narrow down and focus on the message that the teacher wants to deliver. This supports better attention and reduces distractions. 

3. Redundancy Principle

Mayer (2009) found graphics beat narration. Use video with voiceover, not video, text, and voice. Too much info overloads learners, says Sweller (1988). This helps learners with SEND, state Clarke and Lyons (2004).

4. Spatial Contiguity Principle

Perhaps this is the common knowledge we have when creating teaching material. This principle underlines the standing of the distance between visuals and text. Designing the illustration close to the text is better than separating them. So, no need for students to scroll their eyes through the screen. 

5. Temporal Contiguity Principle

Mayer (2009) showed learners understand better with combined words and pictures. Sweller (1988) and Chandler & Sweller (1991) believe active learning aids comprehension. Separating words from images can overwhelm the learner's memory.

6. Segmenting Principle

Learners understand material better with breaks (no source). Presenting too much new content can confuse learners. Give learners control over how quickly they learn (no source).

Advanced Multimedia Teaching Strategies

1. Pre-training Principle

Learners grasp new topics more easily with prior knowledge. Teach core concepts first. For instance, learners need evaporation before the water cycle. Smith (2020) and Jones (2022) showed pre-training improves learner involvement.

1. Modality Principle

Mayer (2009) found learners learn best with graphics and narration. Learners process information better this way, compared to on-screen text. Sweller (1988) showed this helps learners who struggle with reading. Paivio (1986) noted audio narration reduces mental effort.

1. Multimedia Principle

Students learn better from words and pictures than from words alone. Visual aids and illustrations can help students understand complex concepts more easily. For example, instead of just describing the different parts of a cell, the teacher can show a diagram of a cell and point out each part as they explain it.

1. Personalisation Principle

Students learn better when the words used are in conversational style rather than formal style. This means using a more relaxed and friendly tone, as if the teacher were talking to the student directly. For example, instead of saying "The student should be able to identify the key components of the system", the teacher could say "You'll be able to spot the key parts of the system". Using a conversational style helps create a more engaging and relatable learning experience for students.

1. Voice Principle

Students learn better when the narration is spoken in a friendly human voice rather than a machine voice. Using a human voice helps to create a sense of connection and trust between the teacher and the student. This can lead to increased engagement and motivation, as students are more likely to pay attention and learn from someone they feel connected to. This is particularly useful in online learning environments, where students may feel isolated or disconnected from their teacher.

1. Image Principle

Adding the teacher's image may not help learners (Mayer, 2009). Focus on essential content, avoiding extra pictures. This cuts visual load, improving learner cognition (Sweller et al., 2011).

Implementing Multimedia in Your Classroom

Review your teaching materials and reduce extra information. Highlight key concepts and add visuals where possible. Segment complex topics into smaller chunks. Narrate slides using a friendly tone. This makes learning more engaging (Mayer, 2021; Sweller, 1988; Paivio, 1986).

Mayer's (2014) multimedia principles help learners understand and remember more. Clark and Mayer's (2016) research backs this teaching method. Use them to engage learners well.

Mayer's 12 Principles: Classroom Quick Reference

Mayer's multimedia principles guide eLearning design (date unspecified). A table helps teachers grasp each principle quickly. Use examples to improve slides, worksheets, and interactive whiteboard materials.

Mayer (2021) found multimedia principles had a large effect (d = 0.75). This shows their strong teaching potential. They rival formative assessment and retrieval practice, researchers say.

Common Multimedia Mistakes in Classrooms

Mayer (various dates) found teachers frequently use multimedia resources. Teachers sometimes unknowingly ignore Mayer's principles, which can hinder learner progress. This guide presents five common errors and provides useful solutions.

Mistake 1: Text-heavy slides. The average teacher's PowerPoint slide contains 40 or more words (Garner and Alley, 2016). Mayer's research shows that slides should contain minimal text with teacher narration providing the verbal channel. A Year 8 science teacher in Manchester cut her slide text by 70% and reported: "The learners actually looked at the diagrams for the first time. Before, they were just copying the text into their books without processing any of it."

Research shows decorative images hinder learning. Smiling kids or cartoons add nothing (Mayer, 2014). Images must directly link to learning goals. Can't explain its purpose? Remove it, says research (Sweller, 2011; Paivio, 1990). Every visual should help the learner grasp the lesson.

Learners struggle with long videos. Segment content into five to seven-minute chunks, say Mayer (2005) and Sweller (1988). Pause videos for questions and discussions, advise Clark and Mayer (2016). This helps learners process information effectively.

Do not read slides aloud verbatim, learners process it twice. This creates interference, not reinforcement (Mayer, 2009). Speak different content as you show visuals. Clark & Mayer (2016) suggest silent reading instead.

Mistake 5: Information overload on worksheets. Worksheets that combine diagrams, text boxes, instructions, tables, and questions all on one page violate the coherence principle. Learners do not know where to look first. Use clear spatial layout with one task per section and white space between elements.

Multimedia Lesson Audit: A Self-Check

Use this checklist before your next lesson to audit your multimedia materials against Mayer's principles. Score each item yes or no. A score of 8 or above means your materials are well-designed. Below 6, revise before teaching.

Use this checklist, teachers, to save time. Practise these principles; lessons will improve. Multimedia helps learners succeed consistently (Laurillard, 2012).
