This course provides learners with a strong foundation in the fundamental principles and concepts of Applied Behavior Analysis (ABA) and their practical application in everyday settings. It explores how behavior is influenced by environmental factors and how behavior-analytic principles can be used to understand, teach, strengthen, and reduce behaviors in meaningful and socially significant ways. Students will examine essential ABA concepts, including, reinforcement, punishment, extinction, prompting, shaping, chaining, stimulus control, motivating operations, and discrimination. The course also introduces the seven dimensions of ABA and highlights the importance of observation, measurement, data collection, and functional assessment in making informed decisions about behavior. Through practical examples and real-world scenarios, learners will develop an understanding of how these principles can be applied across educational, clinical, home, and community settings. Emphasis is placed on ethical, individualized, and evidence-based practice, including the importance of client dignity, effective intervention, generalization, and collaboration with families and other professionals.
