What have Online courses taught us?
Daphne Koller TED speech regarding ONLINE courses

Sixteen Minute Mark:
discusses the power of customization/personalization
Identifies Ben Bloom's 1984 study regarding
lecture method compared with mastery method compared with individual tutoring method
2 sigma benefit - 98% of students receiving an above average education

How does a world in which electronic devices proliferate in the form of hybrid/online/customized/mastery approach enable a school to achieve the 2 sigma rate of success?

Online Education PBS story - how is online learning changing traditional learning

In 1980, if you wanted to know the weather, you waited for the 6pm or 11pm news. 
In 2013, the Weather Channel and weather apps provided 24/7 access to weather information.
In 1980, if you wanted to know the score of last night's game, you waited for the 6pm or 11pm news.
in 2013, ESPN has multiple television, radio and online apps to provide the information 24/7.

In 1980, if you wanted to study the quadratic equation, a math teacher covered that topic during the third week of the second month for 45 minutes each day.
In 2013, if you want to study the quadratic equation, you can go online for a video lecture on the subject 24/7 and take interactive practice tests to assess your mastery of the material 24/7.  
Educational Productivity has evolved to 

Educational Model: 25 students with one teacher for 45 minutes 180 days a year = your opportunity to learn.  Monday - Friday at 10am.
Teacher insists on the value of attending and participating daily as necessary to learn and make progress, but the learning process requires

What is the value of the instructor?
  • guide
  • mentor
  • facilitator
  • inspirer
  • motivator
  • leads the process of learning as a structured activity
  • establishing high expectations
  • challenging & affirming
  • Promote collaboration, problem solving, creativity, communication by students
  • Catholic schools - role model, promotion of key values/virtues such as integrity, character, excellence, perseverance, faith, kindness
 What is the importance of learning together with other students?
  • collaboration
  • socialization
  • raised expectations
  • positive "tidal wave" effect
  • collective value of work ethic
 What is the importance of class size?
  • improved personalization
  • customization
  • one on one time with a teacher
  • maximize adult-student interaction

What is the value of meeting at a set time on a daily basis?
  • structure
  • organization
  • habit

Challenge: 
How does a school improve its productivity by creating the 2 sigma solution with a greater than 25 to 1 student-teacher ratio? How does a school bring to bear the benefits of online/hybrid learning without losing the benefit/value of great teachers leading the learning?

Will education look the same in 10 or 20 years?
Is the status quo going to survive?
Can the status quo survive given the economic consequences of our instructional model?
Who is going to "invent" the new model without a bleeding edge impact on students?
What are the best practices of our current instructional system?
What will be the impact on other schools?
What if tuition costs could be cut in half due to efficiencies/productivities not currently being realized by the industrial model of 180 days, 45 minutes per period, 25 students per teacher?
