    Hi Ryan,

    Thank you for your comment!

    One of the historical lessons that I am trying to point to is that this type of the research (and the types of studies used in media comparison efforts) makes it nearly impossible to identify the variables that influence learning. The comparison between face-to-face and blended is not a comparison of 1 variable. Therefore, when significant differences have been observed for blended delivery models for example, it's generally unclear whether those were the result of technology or the result of a concomitant change in the learning environment (e.g., more time spent on task). This article discusses some of these issues and suggests an alternative research design for improving learning in these contexts: http://www.educationaldesigner.org/ed/volume1/issue4/article13/

    But this isn't pure media vs media comparison, as per those who watch a live lecture vs those who watch the same lecture on YouTube. The description states that the Khan resources will be "integrated into normal classroom activities". So the comparison will be between traditional classroom-based delivery and blended delivery, which will yield much more useful results... no?
