Over the past decades, Learning & Development has become an area of growing interest and constant research. As a result, there is an abundance of studies and models that target the development of educators. However, the professional development of educators should be built on a comprehensive framework of research-based instructional strategies that help train them on how to understand, experience, practice and leave a sustainable impact on learners. This paper presents our own "FIRST Framework", a holistic framework designed on the basis of renown models and theories, such as: experiential learning; Gamification and game-based learning; facilitative learning, 6Ds model, positive psychology, experience economy and neuroscience. It is an engaging framework that helps educators bridge theory and practice to create high-quality learning environment in their classrooms. FIRST Framework consists of 5 domains with 15 principles that help leave sustainable impact on learners through promoting Active Deep Learner Experience.
