Why Video Evidence is Reliable and Valid
Videos are reliable because they can be viewed by numerous people with the same or very similar findings. The videos can be viewed repeatedly to determine whether the child was reading. Videos are valid because they can capture what the camera sees and the microphone hears. Unaltered home videos made by parents are reliable and valid evidence that babies can learn to read from consistently seeing and hearing language. Videographic evidence is reliable and valid and it is already used in many studies. In many sports, it is considered more valid and reliable than referees’ direct observations and it can be used to overturn their decisions. In fact, retrospective videographic evidence has been used in scientific studies even in cases where no specific skills were being videotaped.
Many parents videotape their babies, toddlers, or preschoolers reading books after using Your Baby Can Read! (YBCR). Some parents specifically mention that their child is reading a new book. Other parents show their children reading signs, birthday cards, or something else that likely was not memorized. In some cases, the reading appears to happen spontaneously. In addition, some of the children read for long periods and there are times where parents write down words and the children sound them out as they are being written.
While it is possible to memorize a storybook that has been read to the child many times, it is a statistical improbability that a child would memorize the order of 10 words that are drawn in a random order. I’ll quickly illustrate the number of permutations of how the words could appear. If one of the words is “clap” it could be in any of the ten positions from first to last. For each position, there is a 1/10 chance that it would be drawn for that position – that would be multiplied by 1/9 X 1/8 X 1/7 and so on, for the other 9 words. Do the calculations – it comes to a 1 out of 3,628,800 chance that a child would be able to guess the order of 10 words drawn at random.
In many ways, this would be more impressive than the baby reading the words. If the baby is reading in the videotape and if the parents taught the baby to read using YBCR, the reasonable assumption is that using YBCR during infancy had a “treatment effect.” A control group for babies reading is not needed since the probability that any of the babies in the control group would be reading is very close to zero. For children who are age four or older, then standardized data could be used as a control.
NOTE: The results in many of the following videos are exceptional. This does not mean that your baby will end up reading at the same levels as the babies and toddlers in the videos. The typical results of using YBCR are that babies and toddlers who consistently use YBCR for at least 6 months learn to read some words and they learn vocabulary skills from using the program. There are many factors that influence how well your child will do with YBCR including your child’s age when starting, whether your child was focused on the words, how many times the child saw words while hearing them, genetic factors, the parents’ strategies while teaching reading, whether or not the parents showed their babies a lot of mindless entertainment-based programs as well as numerous other factors.
