what is observation

Observation can be defined as the act or instance of noticing, perceiving, or regarding attentively. It involves recognizing and noting a fact or occurrence, often through the use of instruments or the senses. In the context of the natural sciences, observation is the acquisition of information from a primary source, and it can involve the perception and recording of data using scientific instruments. Observations can be qualitative, where only the absence or presence of a property is noted, or quantitative, where a numerical value is attached to the observed phenomenon by counting or measuring. In educational settings, observation involves paying close attention to behaviors, interactions, activities, and interests, and noticing all aspects of development. Observations can be overt (subjects know they are being observed) or covert (subjects do not know they are being watched) .
