This document examines learning theories of behaviorism, cognitivism, and constructivism. It provides an overview of each theory and how they relate to the author's teaching philosophy. The author believes constructivism and cognitivism align most with creating a meaningful learning environment where students can build on prior knowledge and experiences to develop a deep understanding of new concepts. The author plans to incorporate aspects of these theories, such as hands-on learning activities and organizational strategies, in their own classroom instructional design.
