Over 120 Years of Treating Learning Difficulties Through Psychology
More than 120 years ago, Dr. Lightner Witmer of the University of Pennsylvania—widely known as a pioneer of American psychology—was heartbroken to discover that many young students were facing severe learning difficulties in school. He began scientifically assessing their intellectual and psychological challenges, and through the clinical-scientific methods of his time, offered step-by-step treatment and customized learning plans tailored to their individual needs.
The Tree Group’s Active Learning Program
The Tree Group’s Active Learning Program supports children suffering from delayed language development, attention deficits, emotional and behavioral disorders, developmental delays, and difficulties in social functioning. Our program empowers these children to build a new life.
Unlike standard educational curricula, the Active Learning psycho-educational program has two key differences.
A Psycho-educational Program is a Clinical Treatment Program
The Active Learning Program is rooted in psychology and designed as a clinical treatment program. Every participant undergoes a comprehensive psycho-educational assessment and an initial diagnostic interview to precisely measure cognitive, intellectual, academic, language, emotional-behavioral, and neuropsychological functioning.
These psychological data are not only used to understand the child’s current academic level but also to diagnose functional difficulties in each domain. Based on this, we develop and apply individualized psycho-educational strategies that serve both treatment and learning goals.
