This paper examines the theoretical foundation and practical applications of an online intervention for children ages 5-11 with ADHD. Coding4Therapy is designed to integrate informal coding education with therapeutic goals, filling the gaps between and within existing educational, pharmacological, and non-pharmacological treatment. Coding4Therapy seeks to improve cognitive and socio-emotional functioning and promote equitable STEM outcomes through personalized courses with multifaceted instruction. This intervention builds on research highlighting the benefits of early STEM engagement, alternative therapies, gamification, and online learning, resulting in a replicable methodology and accessible application.
