Schema theory in psychology is a conceptual framework that posits our knowledge of the world is organized into units called schemas, which are mental structures that represent some aspect of the world. Schemas are acquired over time through learning and experience, and they help us categorize and interpret new information by providing a structure for understanding the events and situations we encounter.

They are the building blocks of cognition, influencing our attention, perception, memory, and problem-solving activities. When we encounter new experiences, our brain tries to match them with existing schemas, which can then be modified to accommodate the new information (accommodation) or used to assimilate the new information into our existing knowledge framework (assimilation).

Schemas also play a crucial role in filling in gaps in our understanding, allowing us to create a coherent narrative from partial information. However, this can lead to cognitive biases if our existing schemas are too rigid or if we overly rely on them, causing us to ignore or distort information that does not fit.

In educational psychology, schema theory is applied to understand how students learn and apply knowledge. It suggests that effective learning involves connecting new information to existing schemas and that educators should facilitate this process by helping students relate new concepts to what they already know. Understanding schema theory is fundamental for educators to design learning experiences that build on students' prior knowledge and encourage the construction of new, more complex schemas. It's a pivotal concept that underpins the cognitive processes involved in learning, memory, and comprehension.
