"Can the expertise we have developed over the past 25 years enable us to produce technologies that enhance learning? The answer-an enthusiastic Yes-came only after deliberating with educators. SAS Curriculum Pathways is the result of those deliberations."
Lodge McCammon's technique for flipped teaching, involving hand-drawn boards and personal lectures. Interesting and potentially powerful, but remember that this is just one perspective on how to accomplish flipped teaching. There are others out there.
Online learning system used by High Tech High. Seems similar to Carnegie Learning.
"Assessment and LEarning in Knowledge Spaces is a Web-based, artificially intelligent assessment and learning system. ALEKS uses adaptive questioning to quickly and accurately determine exactly what a student knows and doesn't know in a course. ALEKS then instructs the student on the topics she is most ready to learn. As a student works through a course, ALEKS periodically reassesses the student to ensure that topics learned are also retained. ALEKS courses are very complete in their topic coverage and ALEKS avoids multiple-choice questions. A student who shows a high level of mastery of an ALEKS course will be successful in the actual course she is taking."
"Here is the problem with the term "Flipped Class:" it implies version one of our screencasting model: that which used to be done in class is now done at home, and that which used to be done at home, is now done in class. In a nutshell, that IS "The Flipped Classroom," but it does not end there, which is why the term "The Flipped Classroom" does not do justice to the many models being used."
