The point is that this approach can be done on scale and automated.

...FYI - This is the Abstract of the mentioned paper<br />which we would like to share here, in the hope we all together can improve the algorithm:<br /><br />"On-line Certification for All: The PINVOX Algorithm"<br /><br />A protoype algorithm: PINVOX (“Personal<br />Identification Number by Voice") for on-line certification is<br />introduced to guarantee that scholars have followed, i.e.,<br />listened and watched, a complete recorded lecture with the<br />option of earning a certificate or diploma of completion<br />after remotely attending courses. It is based on the injection<br />of unique, randomly selected and pre-recorded integer<br />numbers (or single letters or words) within the audio trace<br />of a video stream at places where silence is automatically<br />detected. The certificate of completion or “virtual<br />attendance” is generated on-the-fly after the successful<br />identification of the embedded PINVOX code by a video<br />viewer student.<br /><br />To apper on: Intern.

The paper does not speak about all these issues, but just about providing a way to be able to tell whether someone <i>watched</i> a video, or sat in front of a screen.<br /><br />In an offline world we can perfectly tell the difference between attending an event and making the best of it. And that is why we sign certificates of attendance to everyone in the room and grades only to the ones that completed an assessment based on what was talked about inside that very same room. And to some of them we will even give degrees if other conditions are met.<br /><br />And that is the idea of PinVOX, to try and certificate just the first phase of the whole process.<br /><br />And I think it works quite good :)<br /><br />i.ismael peña-lópezhttp://ictlogy.netnoreply@blogger.comtag:blogger.com,1999:blog-21077063.post-69115265316900722332012-06-11T13:34:32.629+00:002012-06-11T13:34:32.629+00:00I disagree.

To simply listen to a one hour lecture just to hear the codes would be more effort than to listen to the content attentively. The cognitive overload is tiny - a few numbers over one hour. However, I do agree that this needs to be tested. These guys have a good track record on researching students use of recorded lectures.Donald Clarkhttps://www.blogger.com/profile/00796341486328270474noreply@blogger.comtag:blogger.com,1999:blog-21077063.post-63634982758823234722012-06-11T11:23:32.376+00:002012-06-11T11:23:32.376+00:00I don't really agree with this.

If we're talking online learning we need to consider cognitive load and this is certainly extraneous cognitive load.teaandorangeshttps://www.blogger.com/profile/00478265337840062888noreply@blogger.comtag:blogger.com,1999:blog-21077063.post-6712888517324406252012-06-10T14:01:12.226+00:002012-06-10T14:01:12.226+00:00Nick.

The bottom line is that lecturers rarely ever bother to make any effort to assess within or beyond lectures - I suppose that's the problem that this addresses.Donald Clarkhttps://www.blogger.com/profile/00796341486328270474noreply@blogger.comtag:blogger.com,1999:blog-21077063.post-88916324150084888372012-06-10T08:45:05.220+00:002012-06-10T08:45:05.220+00:00This doesn't sound too great to me.

I've just been trying a free service called Vialogues which i think could work well: https://vialogues.com/ I reviewed it here http://quickshout.blogspot.co.uk/2012/06/engage-students-with-flipped-video.html It enables you to add questions and polls at specific times as the video progresses. Students can then add their comments and respond to the polls as they listen. This makes listening much more active.<br /><br />Best<br /><br />Nik PeacheyNik Peacheyhttps://www.blogger.com/profile/13397596906147004693noreply@blogger.comtag:blogger.com,1999:blog-21077063.post-73703999668139457532012-06-10T07:30:06.844+00:002012-06-10T07:30:06.844+00:00This is an interesting idea, but why not simply pu...This is an interesting idea, but why not simply put them through a quick online assessment based on the lecture?
