Hi Drallison, I am the co-creator. This is my biased description... My 14 year old son said that he was surprised to learn how fast 30 mins goes by when using DnsLearning. Encouraging children to come up for air every 30 mins is a good thing. My 9 year old daughter went to Khan Academy 7 times one day during the summer. This means she was watching a lot of youtube videos. I told her I was impressed how many times she went to Khan Academy. She responded. "Yea, well I got tired of doing Khan Academy so I decided to clean my room instead." So, for those 2 cases, for my 2 children, it has been effective :)
