Q & A

What is the main principle of multimedia learning as discussed in the video?

The main principle of multimedia learning is the multimedia principle, which states that using words together with graphics, or multimedia, leads to better learning outcomes than using words alone.

What is the cognitive theory behind multimedia learning according to Professor Mayer?

Mayer's Cognitive Theory of Multimedia Learning is based on three key assumptions: the dual channel assumption, the limited capacity assumption, and the active processing assumption.

What does the dual channel assumption suggest about how learners process information?

The dual channel assumption suggests that learners process information through separate channels for audio and visual inputs, and that words and images are initially processed separately before being integrated.

How does the limited capacity assumption affect the design of educational multimedia?

The limited capacity assumption implies that both the visual and auditory channels have a limited capacity for processing information at one time, which means that overloading these channels can hinder learning.

What is the active processing assumption and why is it important for learning?

The active processing assumption states that learners must actively engage with the material by extracting relevant information and integrating it with their prior knowledge. This active engagement is crucial for effective learning.

What are the three types of cognitive processing that occur during multimedia learning?

The three types of cognitive processing are extraneous processing, essential processing, and generative processing. Extraneous processing drains cognitive capacity without contributing to learning, essential processing involves organizing relevant information in working memory, and generative processing involves building upon prior knowledge.

How can instructional design techniques be used to enhance multimedia learning?

Instructional design techniques can be used to reduce extraneous processing, manage essential processing for more efficient information intake, and foster generative processing for deeper understanding and retention.

What are Mayer's Principles of Multimedia Design and how do they relate to cognitive processing?

Mayer's Principles of Multimedia Design are a set of guidelines derived from research that aim to reduce extraneous processing, manage essential processing, and foster generative processing, aligning with the cognitive theory of multimedia learning.

Can you provide an example of a principle that reduces extraneous processing?

The coherence principle is an example that reduces extraneous processing by minimizing irrelevant information and focusing on the essential content.

What is the purpose of the segmenting principle in multimedia design?

The segmenting principle aims to manage essential processing by breaking down complex information into smaller, more manageable segments, making it easier for learners to process and understand the material.

How does the personalization principle contribute to generative processing in multimedia learning?

The personalization principle contributes to generative processing by making the material more relatable and engaging for the learner, which can encourage deeper reflection and integration of new information with existing knowledge.

Highlights

A good educational video is based on decades of research into the effect of multimedia on learning.

Professor Mayer at UC Santa Barbara has developed a set of principles from multimedia learning research.

The multimedia principle states that words with graphics lead to better learning than words alone.

Understanding the effectiveness of multimedia requires a basis in cognitive theory.

Mayer's Cognitive Theory of Multimedia Learning is based on three key assumptions.

The dual channel assumption: separate processing channels for audio/visual and words/images.

Expert learners can form mental pictures from words and descriptions of images, allowing channel crossover.

The limited capacity assumption: each channel has a limited capacity for processing information at one time.

Avoid overloading the visual channel with too much text and graphics simultaneously.

The active processing assumption: learners must actively organize and integrate information with prior knowledge.

Our brains do not passively process information; we actively decide what is relevant and important.

Three types of processing: extraneous, essential, and generative.

Extraneous processing drains cognitive capacity without contributing to learning.

Essential processing involves pulling out relevant information and organizing it in working memory.

Generative processing reorganizes new information and builds upon prior knowledge.

Instructional design techniques can alter the types of processing students go through.

The goal is to reduce extraneous processing, manage essential processing, and foster generative processing.

Mayer's Principles of Multimedia Design aim to reduce extraneous processing and manage essential processing.

Some principles foster generative processing, such as personalization, voice, and image principles.

Transcripts

When you watch an educational video it's hard to  tell how much work and thought and research went  

into that video. In reality a good educational  video has been based on research that has been  

done over decades into the effect multimedia  has on learning. In fact Professor Mayer at UC  

Santa Barbara has drawn an ever expanding set  of principles from this ever-expanding body  

of research. The key principle is the multimedia  principle which states simply that words together  

with graphics which is called multimedia leads  to better learning than simply words alone.  

In order to really understand why this would be  however we first need a basis in cognitive theory.  

So in this video we will discuss the cognitive  theory behind multimedia learning and by the end  

of this video you should be able to describe the  three key assumptions this is based on as well  

as differentiate between the different types of  processing that our brains utilize while learning  

from multimedia. Mayer's Cognitive Theory of  Multimedia Learning is based on three assumptions.  

First the dual channel assumption is that  learners process information through separate  

channels based on whether it is audio or visual  and whether it is words or images. Information  

taken in via the visual channel can be written  words or graphics for example while verbal  

words are taken in via the auditory channel.  However after they have been taken in all words  

are then thought to be processed together in a  separate channel from graphics. Interestingly  

expert learners may have the ability to form  mental pictures from words and mental descriptions  

of images thus allowing these bits of information  to cross over from one channel to the other.

Second the limited capacity assumption  states that any channel has a limited  

capacity for material at one time. The  visual channel may be overloaded by  

putting both graphics and significant  text on the screen at once. Likewise  

asking the brain to process both written and  spoken text at the same time is not ideal.

And third the active processing  assumption is that in order to learn  

learners must pull out relevant bits of  information from the information they receive  

and organize and integrate them with respect  to each other and to their prior knowledge.  

Our brains do not have the ability to passively  process all of the information we're given  

and then play it back word for word.  Rather we actively decide what parts of  

the material are relevant and important and  weave those into our knowledge scaffolds.

While trying to learn from different  sorts of material or situations  

our brains perform three  types of processing. These are  

extraneous processing which drains  cognitive capacity without learning.

Essential processing in which we are pulling  out relevant information from what we take in  

and organizing it in our working memory. And  generative processing in which our brains  

reorganize new information and build  upon our prior knowledge scaffolding.

Through use of instructional design techniques  we can alter what sort of processing our students  

go through. Our goal is to reduce extraneous  processing which wastes our cognitive capacity,  

manage essential processing allowing us  to take in information more efficiently,  

and foster generative processing which  leads to deeper understanding and retention.

So how can we apply this cognitive  theory to effective multimedia creation?  

Lots of research has led to Mayer's  Principles of Multimedia Design.  

Some of these principles work towards the goal  of reducing extraneous processing. For example  

the coherence signaling redundancy spatial  contiguity and temporal contiguity principles.  

Some of the principles work towards the goal of  managing essential processing; for example the  

segmenting pre-training and modality principles.  And some of the principles work towards fostering  

generative processing for example the  personalization voice and image principles.

To learn about these principles and how  to apply them if you haven't already
