Online Education - Introducing the Microlecture Format by Thomas Most college students would likely concur - fifty minute lectures can be a bit much. With current research indicating that attention spans (measured in minutes) roughly mirror a students age (measured in years), it begs the question as to the rationale behind lectures of such length. teddY-riseDGiven that it is tough to justify the traditional lecture timeframes, it is no surprise to see online educational programs seeking to offer presentations that feature shorter podcasts. But in an astonishing switch, David Shieh of the Chronicle of Higher Education recently took a look at a community college program that features a microlecture format, presentations varying from one to three minutes in length.

What it Means to Educate Today's Students February 4th, 2009 Comments The Carnegie Foundation is focusing on where and how technology can add value as we seek to advance more ambitious learning goals for all students, and where we can assist educators as they move toward making these new learning goals universal. The Foundation has enlisted expert advisers to help us look at how technology is transforming how we educate. One of these advisors is Nichole Pinkard, Director of Innovation at the Urban Education Institute, University of Chicago.

The Meyer and Land Threshold Concept "The idea of threshold concepts emerged from a UK national research project into the possible characteristics of strong teaching and learning environments in the disciplines for undergraduate education (Enhancing Teaching−Learning Environments in Undergraduate Courses). In pursuing this research in the field of economics, it became clear to Erik Meyer and Ray Land [1−6, 7−12], that certain concepts were held by economists to be central to the mastery of their subject. These concepts, Meyer and Land argued, could be described as 'threshold' ones because they have certain features in common." Glynis Cousin, An introduction to threshold concepts Over the past five years this concept has been embraced by many disciplines outside economics; indeed the above quote is from Glynis Cousin's excellent short introduction to the concept written for earth scientists. The threshold concept has been seen as a valuable tool, not only in facilitating students' understanding of their subject, but in aiding the rational development of curricula in rapidly expanding arenas where there is a strong tendency to overload the curriculum (Cousin, [1, 13]). This web page will describe, briefly, the characteristics of a threshold concept and list selecteted references to the work of those examining its value in the engineering and computer sciences, the physical and biological sciences, economics, accountancy, mathematics and statistics.
