Online education: transparency and visibility

Together with two learning partners of a master's degree that I'm attending, I created this video that focuses on how transparency thought support some learning activities on the credit unit PPEL, because we believe that our course has great potentialities within cooperative learning theory. We hope that this idea is clear on the video.
Unfortunately, I'm not able to guarantee a video with a good image, by posting it on Youtube. Although the sound is perfect, it seems that some visual quality is at risk there...

Everybody cited on the video kindly allowed us to use their personal data.

Well, enjoy it and feel free to comment.
