C.6 Design and apply discontinuous measurement procedures

Discontinuous measurement procedures are tools used to monitor and track behaviors effectively, especially when it's not feasible to observe continuously. These methods allow parents, teachers, and practitioners to collect valuable data about student progress while focusing on specific intervals of time. Here’s a breakdown of the main types:

Word	Definition
Time sampeling	It is a way of measuring behavior that involves recording it at specific intervals or moments of time. This can be done by dividing the observing time into intervals of equal length, such as 20 seconds, 5 minutes, or 1 hour.
Interval	Is a specific unit of time used to divide observation time. Intervals can be any length, such as 20 seconds, 5 minutes, or 1 hour.

Total Interval Recording The observer records whether a behavior occurred throughout the entire interval. When to use: Use this method for behaviors that should be continuous or sustained for the duration of the interval. Examples: Recording whether a student sat in their seat for a full 5-minute period. Checking if a child brushed their teeth for the entire 2 minutes. Observing if a student kept their eyes closed for 10 seconds during a mindfulness exercise.

Partial Interval Recording The observer notes if the behavior occurred at any point during the interval, regardless of how long it lasted. When to use: This is useful for tracking behaviors that don’t need to be continuous but occur within a specific time frame. Examples: Observing whether a student raised their hand during a 5-minute interval. Checking if a player passed the ball at least once during a game interval.

Momentary Time Sampling The observer records whether a behavior is happening at the exact moment the interval ends. When to use: This method is ideal for tracking behaviors periodically rather than continuously. Examples: Observe whether a student is looking at the teacher at the end of each 15-second interval. Checking if a participant is focused on the speaker during the final moments of a presentation.

Planned Activity Check (PLACHECK) A specialized version of momentary sampling, PLACHECK is designed for group settings. The observer checks whether the behavior occurred across a group of individuals at the end of the interval. When to use: Perfect for assessing group participation or engagement. Examples: Checking if all students in a class are seated at the end of a 5-minute interval. Observing whether children in a ballet class are dancing to the Nutcracker. Ensuring students are writing during a dictation exam.

Discontinuous measurement procedures help educators and parents:

• Save time: By focusing on specific intervals rather than continuous observation.

• Track progress effectively: Monitor behaviors in structured ways that inform decisions.

• Adjust interventions: Identify patterns to improve teaching or behavioral strategies.

🔑Key Takeaways🔑

• Total Interval: Did the behavior happen for the whole time?

• Partial Interval: Did the behavior happen at any time?

• Momentary Sampling: Did the behavior happen at the interval’s end?

• PLACHECK: Did the group meet the behavior goal?

By using these methods, you can measure behavior efficiently and ensure students are on track to succeed.

Questions to Consider:

1. Which behaviors are most important to monitor right now?

2. Which measurement method fits the goal or setting best?

3. How can this data help adjust learning strategies for success?
