How do you optimise your slides, audio or video when delivering online teaching?

There are many learning theories out there, but Mayer’s Multimedia Learning Theory is epic.

Read this thread + use his theories to improve learning transfer

Non-ideal slide to get started👇

1/17
The theory has 3 main assumptions:

1. Dual channels: there are 2 channels (auditory + visual) for processing info from sensory memory

2. Limited capacity: each channel has a limited working memory capacity

3. Active processing: multimedia learning is an active process

2/17
And 5 cognitive processes

1. Select relevant words from text/audio
2. Select relevant images
3. Organise the words into a coherent verbal representation
4. Organise images into a coherent pictorial rep
5. Integrate 3 + 4 w/ prior knowledge

Mayer's principles optimise this
3/17
Multimedia principle

People learn better from words and pictures than words alone. Words and pictures together let the learner construct both visual and verbal models which leads to better learning transfer

4/17
Coherence principle

People learn better online when unnecessary content is removed from slides.

This includes text, sounds, images.

Extra material competes for cognitive space + means the learner won’t remember it as well.

Keep it uncluttered.

See 👇

5/17
Signaling principle

We learn best when we are shown exactly what we need to pay attention to on screen

Show your audience by highlighting words/sections to indicate significant info.

This can be verbal too - with emphasis on specific words.

XR rule of twos 👇

6/17
Redundancy principle

Humans learn best with narration and graphics, rather than narration + graphics + text.

Redundant material interferes with learning, because the learner has to process multiple sources.

Key point: don’t read the text out loud from your slides.

7/17
Spatial contiguity principle

Keep words + pictures near to each other.

This makes it easier for learner not to have to scan the screen and put things together.

It reduces cognitive load and improves learning transfer.

See the example below👇

8/17
Temporal contiguity principle

It's better if images + the words accompanying them are presented simultaneously rather than successively

Rather than showing an image + THEN talking it about it, do both together.

Learners retain more this way.

See SVT example👇

9/17
Segmenting principle

People learn better when the content is split into user-paced segments. This is really for pre-recorded content on a LMS.

Rather than showing a 1 hour lecture, split it into 10 min segments + allow the user to press play to move on when they want to

10/17
Pre-training principle

Learning is better if the audience knows the core concepts in advance. Providing some pre-reading or ensuring a base line expected knowledge allows the nuance to be discussed in the session.

This is particularly effective for complex material.

11/17
Modality principle

We learn better from images + spoken word than from images + text.

This doesn't mean never use text, but if there's too much it's overwhelming + reduces learning.

Remember subtitles for accessibility though.

See auricular block example👇

12/17
Personalisation principle

People learn better in online presentations when the words used are conversational rather than formal.

Keep the language simple + casual.

Consider your audience + try to match the tone to them.

Use first person language.

Example 👇

13/17
Voice principle

People learn better when the narration is spoken in a human voice rather than a robot voice (yes, this is seriously a thing).

So put your robot away.

14/17
Image and Embodiment principle

People do not learn better when a STILL image of the speaker is shown on the screen, but they do when the speaker is on screen and displays high embodiment: hand gestures; eye contact; drawing things on screen.

Be enthusiastic.

15/17
Generative activity principle

People learn better when they have guided generative learning tasks in teaching (summarising, self-testing)

This type of activity causes the learner to process info: select what’s important; mentally organise it; integrate w/ prior knowledge
16/17
This theory isn't perfect (see litfl.com/cognitive-theo… for some criticisms), but it's a lovely model to help frame your thinking about how you use media to enhance your teaching and presentations.

Virtual conferences/presentations to larger audiences are a challenge. There are pros and cons of pre-recording sessions.

It’s not a case of:

Pre-record = bad
Live = good

There is nuance.

A thread...

1/12
Make the decision that serves the core groups' interests best (in order of priority):

1. The audience - must learn + feel connected
2. The speaker - must feel supported, empowered, + valued
3. The organiser - must be able to practically deliver

2/12
As speakers we prefer a F2F audience. We like to hear them laugh at our great jokes, gasp at the cliffhangers, + know when their eyes drift so we can pull them back.

We can’t do this in a virtual presentation. We must accept this and adapt what we do.

Minor burns are a common Paeds ED presentation.

Do you know how to assess them and treat them?
Do you deroof your blisters?
Do you know how to calculate the total body surface area of the burn?

See DFTBSkinDeep.com for more burns pictures

A thread

Get a clear history. Pulling a cup of tea off the counter is a common causes of burns in young children.

How long ago had the tea been made?
Was there milk in it?
What was the child wearing?

Get all the details including who was there at the time.

2/12
Has simple first aid been completed? Run the burn under cool water (15-18°C for 20 mins) within 3 hours.

Toothpaste/jam/honey don’t work.

The zone of stasis has potentially reversible damage. Don’t let the patient burn more. Cool the burn.

The pandemic has posed new challenges for deaf staff. Inability to lip read through masks, noisy environment, masks muffling sounds all pose new barriers. In our departments, it’s our job to provide support for trainees/staff. A thread - thanks entirely to @DocFizzabella

1/11
Embarrassingly this isn’t something I’ve had to think about before. Thanks to @DocFizzabella (who is joining us @RLHPED later this year) my awareness is higher. She has provided me with this wonderful framework for support. It's things we can all implement in our department

2/11
The trainee can apply for Access to Work, a gov funding programme of up to £60k per year per person to pay for all necessary equipment such as radio microphones, transcription service, upgraded hearing aids if required plus many other things that may meet their needs.

Tech things to consider when delivering online teaching:

1. Can your audience access it?

Is there a simple link to access and does everyone have it?

What will you do about last minute registrations?

Does the software you use have a max audience number and is that ok?

1/10
2. Do you know how to show what you need?

Can you share your slides and screen without having to say 'can you see my screen now'? Are you using polls and do they work?

Practice. Practice. Practice.

The tech should be smooth to allow the focus to be on your content.

2/10
3. Do your guests know what they are doing?

Run a tech check with them beforehand but make sure it's on THE SAME device and internet connection that they will use on the day.

Make sure they wear clothes that don't strobe on camera. Make sure you can hear & see them well.

Level up your online teaching sound quality. Allow the audience to concentrate on you and not your crackling audio. Online teaching isn't going away - embrace it.

Think about:

Choosing a mic + positioning it
Optimising your room size/echo
Reducing background noise

1/5
Don't use your comp mic. Two broad mic types to consider:

-A dynamic mic - good if you can be close to the mic & need to filter out background noise.

-A condenser mic - captures more delicate sounds, good if you want the mic to be out of shot

Range of prices for each

2/5
Room size/echo. Can you reduce the echo in the room?

This can be done just by putting a rug on your floor (if you don't have carpet) or a screen up. Foam sound panels are cheap + can go on the wall near you

Small changes but can make a big difference to sound quality

2020 is ending and it's time for me to reflect on the year for
@DFTBubbles

This is a team I truly love being part of - friendship, community, connection, learning, along with breaking new ground every week in a way that always surprises me.

A thread: 1/9
This year our website views have continued to increase, surpassing 1.5 million. This has been a labour of love over 7 years and it due to building a system where we can produce regular, quality content. Thanks to all who have contributed.

2/9
We got referenced in two WHO documents on return to school during COVID, something that I think we would have laughed at the thought of happening when we started in 2013.

This is thanks to @apsmunro leading the COVID data analysis team in what has been a spectacular effort
