Types of observations

Check lists

Check lists are primarily descriptive and indicate the presence or absence of a characteristic. They provide basic information on a wide range of behavior and characteristics. Checklists are most appropriate for answering yes/no items or for documenting a large number of behaviors in a short period of time.

Example

Scaled ratings

Scaled ratings are more precise measures that indicate the degree to which a characteristic or behavior is present or true. The most commonly used scales have five points with a mid-point that indicates neutrality or "average."  [more] 

Example:

Interval observations

Interval observations record the frequency of a behavior or characteristic. An observer documents what is taking place in the classroom or instructional program at regularly timed intervals (e.g., every five minutes). Behaviors are documented using a checklist or a scaled rating system.

Example

Narrative comments

Narrative comments or notes are part of observations. Observation forms may include space after each item for the observer to explain the rating or there may be space at the end of the form for general comments. Observers may record additional comments/notes immediately following the observation to supplement those taken during class.
