People who struggle with a task can benefit from targeted and repetitive practice. Just as a golfer might practice a pitch shot over and over until it becomes second nature, a student learning to read needs to practice key skills. In a classroom of struggling readers with different needs, teachers simply don't have time to set up tailored practice drills for every child.
Smart technology is great at this. If it's adaptive, it knows which skills a student is struggling with and can tee up the right kind of practice until it knows the student has mastered it.
