To further elaborate on question 1, how does the technology help learners:
an infograhic can be used in Gagnes first event, ie gaining attention: it instantly capture's the learners attention and allows learners to derive individual relevance. Plus resonance, a well designed infographic can have impact on comprehension and understanding - which correlates with increased knowledge retention.  This is an interesting article looking at infographics to support online learning. It links to the principles of multimedia learning and reducing cognitive load that we covered in the pre course reading tasks, and the research study (using infographics as course summaries in a MOOC) looking at retention, comprehension and appeal for learners, plus downloading for future reference.  

And for teachers, creating the summary infographic helps them reflect on their own content delivery by having to represent it in a succinct visual manner - which may then improve their teaching practice.

i). Auditory cortex - which processes the incoming sounds (pitch and volume), both sides of the brain contain this region. So you can actually 'hear' both inputs at the same time.

ii). Broca/Wernicke network - This network processes and makes sense of the spoken word - however it only exists on one side of the brain.  Oral speech is therefore funneled into a singular brain network.  So if there are simultaneous oral inputs it leads to a 'bottleneck'.

iii). Left inferior frontal gyrus - This region controls the 'bottleneck'. So when we are trying to understand two oral inputs this region blocks one while the other is allowed to pass through and is decoded for understanding.

Step 2. Gain attention and present stimulus
Statement to stimulate and hook attention
Science shows people can't read and listen at the same time

(Deep within your head there is a voice reading aloud each word as your eyes pass over it - that voice is your own.)
Activity follows to present the information: reading a passage to recognise the voice in the head, this is followed by the diagram (video) explaining the concepts

...Note: if audio is added learning will be more effective (modality principle - humans learn best from visuals and spoken words)

Step 3. Learners are then provided with the flashcards to recall/retrieve the concepts - this could also be 'spaced out' and or tested the following week, in order for learners to recall from memory (retrieval practice)

THis was a post in a newsletter I subscribe to, I havent been through them yet - but would be interested if you have heard of them - particularly Blender??
