	Module 4: Data Collection Types of Data Duration Recording Duration recording is used to record the length of time an individual is engaged in a specific, discrete or continuous behavior. Like event recording, any behavior that you record with duration recording should have a clear beginning and ending, so that you know when to start and stop recording the time. An example might be the length of time a student reads independently during silent reading time or the length of time a student spends out of his seat during math class. Duration recording is used when the primary concern about the behavior is the length of time the student is engaged in that particular behavior. A data collection sheet for duration recording can be found here. This data sheet lists the criteria for starting to record a behavior (such as the student’s pencil begins to write on his worksheet) and the criteria for stopping recording the duration of the behavior (such as the student’s pencil leaves the paper for more than 10 seconds and the student isn’t asking the teacher a question). You can use a timer or stopwatch to record this type of data. An online stopwatch can be found here. Review: You can use duration recording to track the length of __________ a person spending doing a certain behavior (such as reading or having a "meltdown"). ____________ recording is used when you are concerned about either increasing or decreasing how long a person spends engaged in a behavior. When using duration recording, you might use a stopwatch to track how long the behavior goes on. You'll need to decide when to start timing the behavior and when to ________. In your behavior definition (that we discussed in previous module), you'll decide when to start the stopwatch. For example, when tracking how long a child spends reading before becoming distracted, you might start the stopwatch when the child opens a book and orients her eyes toward the page. You might stop the stopwatch when she looks away from the book or closes it. Next --> Types of Data Continued
