Class Notes 6-29-10

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
   

Jacob leading the discussion on the Mason & Bruning

    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
   
    Similar game tux command
   
TED TALK

Elizabeth Gilbert

    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
