Methodology is a system of methods and principles used to do something, especially to study a subject or solve a problem. Think of it as the organized approach someone takes to figure things out or accomplish a goal.

Scientists use scientific methodology when they conduct experiments: they form a hypothesis, design tests, collect data carefully, and draw conclusions based on evidence. A teacher might use a specific methodology for teaching math, like starting with concrete objects (actual blocks to count) before moving to abstract numbers. A detective investigating a crime follows a methodology too, systematically gathering clues, interviewing witnesses, and eliminating possibilities.

The word emphasizes having a logical plan rather than doing things randomly. If you're trying to memorize your multiplication tables, you might develop your own methodology: practicing the hardest ones first, using flashcards, or creating songs to help you remember them. Someone studying how kids learn to read might compare different teaching methodologies to see which works best.

Methodology differs from a single method because it describes the entire framework or philosophy behind your approach. It includes what you do, plus how and why you do it that way. When researchers describe their methodology, they're explaining their whole system so others can understand, evaluate, or repeat their work.
