Since SSR involves substantial amounts of natural reading, it is probable that this practice fosters vocabulary growth. The researchers state that the findings indicate that reading is a most effective way to produce large-scale vocabulary growth. This study supports the hypothesis that incidental learning from context during free reading is the major mode of vocabulary acquisition during the school years. They also checked the books out and were encouraged to read at home. The Gates MacGinite Reading Test was administered before the study and 9 months later.
Results show that all students have improved in their reading level.
Compared with the control groups, students participating in the project demonstrated better reading strategies when having trouble reading a book. Coley thinks that the result of Project READ lends strong support for the inclusion of a period of non-stop reading daily. Shifts in Attitudes Attitude changes towards reading have also been observed. They had read a lot more since SSR was implemented into their reading classes. They monitored the summer reading habits of both students who had, and those who has not been exposed to SSR during the previous school year.
