This document discusses technical and operational definitions. It begins by stating the lesson objectives of defining technical and operational definitions, identifying the differences between them, and doing an activity. Examples of technical definitions, which describe physical components and characteristics, and operational definitions, which focus on practical use, are provided for objects like cars, computers, and books. Students are then instructed to identify underlined words in sample sentences as having either a technical or operational meaning. The importance of understanding both definitions in research and studies is discussed. Students are assigned to write the technical and operational definitions of various words.
