Let’s take a look at two sample sentences from Kindergarten students:

Cute kids using complex sentence structure

Who do you predict will be the better reader by 3rd grade? Child A uses higher level vocabulary (frustrated, someone, home), more complex sentence structure (to find someone had…), and is more specific and clear.

There’s abundant research to show that children who enter Kindergarten with more developed language skills (like Child A) learn how to read more easily.

What contributes to differences in language development?

A well-known study by Hart and Risley1, professors at the University of Kansas, looked at the relationship between a baby’s language experience in the home environment and language development. They found that there was a strong relationship between language experience, vocabulary development, and socioeconomic status (SES).

30 million word gapThe researchers began by looking at language exposure of children 7 to 9 months of age. All language experiences with the children were recorded, transcribed, and analyzed during monthly one-hour recordings for about two and a half years. Researchers then extrapolated the cumulative experiences out to 48 months (4 years – the start of pre-school) and organized the data by socioeconomic status (SES). As you can see, the study shows a 32 million word difference between the children of professional families and those from welfare families.

Also, note the slope of the lines. Not only do these children differ in prior experience once they attend school, but the differences will continue to become greater over time.

When you consider that language experience and vocabulary development are a major part of the brain’s toolkit for representing, manipulating, and retaining information in learning to read, these highly varied differences present a daunting challenge for educators in the classroom.

How do these differences in language experience impact students when they begin school?

On the graph below2 we can see the effect that weakness in oral language development has on students learning to read.

Over time, small differences in oral language skill of 5 and 6 year olds grow into a significant reading gap by the time students are in middle school.

The weak language foundation manifests into a huge literacy gap.

Reversing the Trend

Here’s the best part: educators can influence a child’s language development quickly and efficiently by applying the best research on how the brain learns.

Reading is the foundation for all school success

Fast ForWord was designed specifically to improve the underlying language skills that constitute the foundation of learning and reading. Good curriculum, a language rich learning environment, and Fast ForWord create an optimal foundation to decrease the achievement gap.

Fast ForWord targets the foundational language skills children need to develop literacy. When you get right down to it, language takes us everywhere!
