HomeNetToo research by Linda Jackson, a psychology professor at Michigan State University, gave internet access to 10-16 year olds in low-income households that had no previous access. They were free to use it as they wanted and the average turned out to be around 30 minutes per day.
The findings were consistent across both genders – the more time the children spent on the web the higher their academic achievement as measured by standard test scores.
The study concluded that the increased reading and comprehension led to increased literacy, which in turn led to improvements across the board (except in maths). Literacy has long been recognised as a predictor in other subjects.
