The document discusses operational definitions. It begins by stating the expected learning outcomes, which are to identify process skills like defining operationally, understand how these skills are used in teaching and everyday life, and appreciate their importance. Next, it provides examples of operational versus conceptual definitions and explains that operational definitions are based on observable actions rather than abstract concepts. The document emphasizes that operational definitions are important for collecting accurate data and outlines steps for developing them, such as identifying the characteristic of interest and selecting a measuring instrument. Several examples are then given demonstrating how to operationally define variables like enjoyment of reading, temperature effects on evaporation, and size of a person. Finally, the definitions provided are identified as either conceptual or operational.
