How the internet works - information theory
Internet sends information in small parts called packets
Packet - Header (contains error correction)
Result - multiplies the big number by error number if it matches the result then it is ok
If it does not come correctly it asks for a resend of the internet
Body - basically a big number
The idea of trying to detect errors and correct them is what makes the communication possible
Communication is impossible with out the loop
The packaging of the information is truly important - the message needs to be important but if your packaging is bad it will never do any good.
When does feedback facilitate …
Common sense can not tell us everything - this is why we have so much conflicting research
Generalizability - how broadly generalizable are the findings
Book - visible learning - a book on meta meta analysis
On average we have 0.4 effect size for just putting a teacher in the room - we therefore need to judge studies based on that .4 effect size and how much it beats that.
We need to have a higher standard to which we hold our research
Page 11 - what I highlighted
p<.001 in statistics is the probability that it is by chance
P values that we generally care about - .05, .01, .001

We can be emotionally swayed in our feedback to the students
The computer sticks with the and does not make unnecessary adaptations - cleavage story..
Time honored tradition in our field is to build taxonomies
Certitude of correct response - High Low
Low certitude
David - pg 7 Persistence of belief even when data does not show it
Pg 12 While no statistical data was collected…..
There is no single type of feedback that is best for each situation - there is a way that we can narrow them down into subgroups
Played Timez Attack - look for types of feedback

Fear of failure hinders creativity -
Should we be afraid of accomplishing the things we want to accomplish in our lives
Sometimes we get caught up our assumptions about types of people and careers
How do you continue on through that fear
Create a safe distance from your work and your life - the idea of a damon or a genius
Takes you out of the responsibility
We need to work hard and hope for the moments of inspiration
Show up for our part of the job!
Shute, Valerie (2008): Focus on Formative Feedback
Error Flagging - showing where the error is - does not necessarily tell you what the problem is
Hints/Cues / Prompts
Informative tutoring - not just generic hints but hints that are based upon the errors that you made
David - cognitive apprenticeship - thinking out loud and helping them come along and learn that thinking process
If you reinforce / motivate a behavior with something when that is taken away then you risk the chance of them becoming disengaging due to the lack of the motivator
