8. Titzer, R. (2010a). The Effectiveness of the YBCR Program on Reading and Vocabulary Skills: Study 1.
Funded by the company Your Baby Can, this study included participants who generally watched Your Baby Can Read (YBCR) fewer than five times per week. All of the infants and children in this study watched the DVDs for at least two months. Dozens of studies show that parental reports of their children’s language and cognitive abilities are reliable and valid measures of their children’s abilities. The study was designed so that the parents had five options for responding: a very positive response, a positive response, a neutral response, a negative response, or a very negative response. None of 440 parents in this study selected any of the negative or very negative responses.
This study found that babies, toddlers, and preschoolers learned to read according to 88% of the 296 parents even though the parents did not show the DVDs as frequently as recommended in the Parents’ Guide. Parental reports indicate increases in vocabularies and other learning from using the program for 98% of the babies (under 18 months of age), 95% of the toddlers 18-35 months), and 100% of the other children (older than 35 months). This indicates that YBCR can work even when the parents don’t follow the instructions as long as the children use the program over at least two months.
Some key findings include:
- 94% of the parents who did not follow the instructions said the YBCR program helped their 0-17 month-old babies learn physical actions.
- When asked “How do you think the YBCR program influenced your child’s overall learning?”
93% of the parents who did not follow the instructions said the YBCR program “helped significantly” or “helped more than any other activity” while none of the parents said that it hurt their child’s learning.
- When asked “How do you think the YBCR program influenced your child’s ability to read?” out of the parents who did not follow the instructions, 88% of the parents said YBCR “helped significantly” or “helped more than any other activity” and none said that it hurt their child’s ability to read.
Note: When YBC owned the data, a different name was used to describe this study. Dr. Golshan, a statistician at a top-ten public university in the US, did the statistical analyses for this study.
