Measuring Behavior Introduction

Data collection is an objective method of measurement that can be used to shape and guide professional judgment. It enables teachers to verify that their behavior management plans or instructional methods are producing the desired outcomes and can also be used to identify and end the use of ineffective teaching practices based on current fads or ideologies rather than on evidence. Teachers who do not use frequent measurement are vulnerable to two types of preventable errors:

1. Continuing an ineffective behavioral or academic intervention when no real improvement in performance has occurred

2. Discontinuing an effective behavioral or academic intervention based on a subjective evaluation

Operational Definitions of Behavior

Prior to data collection, educators should define the problem behavior (also known as the target behavior) and the desired behavior (also known as the replacement behavior).

When a problem behavior is to be decreased, it is a good idea to select an incompatible replacement behavior. For example, consider a case where a student’s problem behavior involves cursing when the teacher asks him a question during class. The replacement behavior could be that the student will use appropriate language when responding to a question during class.

Educators must operationally define the target and the replacement behaviors—this is, they must state them precisely in observable and measurable terms. When a behavior is described in observable terms, it can be easily seen and documented. When it is stated in measurable terms, the behavior can be quantified in some way (e.g., counted, timed). Examples of good and poor operational definitions can be found in the table below.

Behavior Observable? Measurable?

FYI After several observations it is easy to drift from the operational definition. To reduce the likelihood of observer drift, educators should review the operational definition frequently. When observing a student’s behavior, the educator should record only what is directly observed instead of interpreting the meaning or intent of the behavior.

Measuring Behavior Level A • Case 1

Background Student: Mark

Age: 12

Grade: 6th

Scenario Mark has been diagnosed with a learning disability. He reads at a second-grade level and his math performance is deficient. He is outgoing and is often described as the class clown. Mark has many friends but often makes them the butt of his jokes. Recently, during reading class, Mark said to Felecia, “Do you think old man McGreevy changed his underwear today?” Two other friends of Mark heard him and started laughing. Felecia laughed, too, but felt kind of uncomfortable. Mr. McGreevy heard the laughter and asked the class to quiet down. A few minutes later when Mr. McGreevy was attending to other students, Mark made a loud noise simulating flatulence. The class burst out laughing. Mr. McGreevy looked at Mark, but Mark said, “I didn’t do anything.” Mr. McGreevy warned Mark that any further interruptions would lead to his being sent to in-school suspension for the rest of the class. Mark feigned indignation and got back to work, but failed to finish his assignment.

The next day, when Mr. McGreevy stepped out of the classroom for a moment, Mark put on eyeglasses and imitated the teacher’s manner. Everyone began to laugh and talk very loudly. Encouraged, Mark continued to cause a commotion. By the time Mr. McGreevy returned, a full-scale ruckus had broken out. Mr. McGreevy sent Mark to the office, the twelfth time he had done so in that school year, and it was only November.

Mr. McGreevy is worried that Mark’s inappropriate behavior will escalate as the winter holidays draw closer. He needs to determine a method that will help him collect information on Mark’s disruptive comments.

Possible Strategies • Event recording • Interval recording

Background Student: Theresa

Age: 10

Grade: 4th

Scenario Theresa rarely finishes her class work. How could she? She’s up, she’s down, she’s wandering all around. Her teacher, Ms. Lowe, seems always to be asking her to return to her desk and begin working. Theresa almost never has her book or her pencil out, and during class transitions she is the last to be ready. Ms. Lowe believes that Theresa’s out-of-seat behavior and procrastination are contributing to her poor grades. She needs to assess the situation and determine which of these behaviors is the most problematic.

Background Student: Johnny

Age: 6

Grade: Kindergarten

Scenario Johnny is a young boy with autism who receives most of his education in an inclusive classroom. He speaks in one- and two-word utterances and can say, “book,” “food,” “more,” “hi,” and “drink.” However, his main mode of communication is a picture-exchange system.

Although Johnny has demonstrated that he really enjoys group activities, he has lately begun biting his fellow students. He seems to pick on Stephen the most. As if this weren’t enough, Johnny has begun pinching his teacher during one-on-one instruction. After he engages in one of these behaviors, he yells, “It hurts!” and starts laughing.

A behavior analyst has conducted a structured interview as part of a functional behavior assessment. The teacher and parents’ responses indicate that the function of Johnny’s aggressive behaviors is to seek attention. However, the analyst needs to directly assess the behavior.

Measuring Behavior Level B • Case 2

Background Student: Alex

Age: 16

Grade: 10th

Scenario Alex has been diagnosed with a learning disability. He reads at an eighth-grade level. Although he is a star athlete, he is not very popular with his classmates. He does not cause much trouble in class, but he rarely finishes his work or turns in homework. He seems to have the capacity to do the work, but gets by with C’s. Mr. Cashman, Alex’s math teacher, spoke to Alex one day about these concerns, to which Alex responded, “I don’t need to work hard. In a few years, I’ll be set because I’m going to be a pro baseball or basketball player.”

Mr. Cashman often lets students work together to finish assignments. During math instruction, Alex works with another student on independent seat-work. One day, Alex looked at Sports Illustrated for thirteen minutes instead of helping with the assignment. When his partner asked him to lend a hand, Alex said, “Man, I don’t get this stuff. Just help me out.” The student continued working. When Mr. Cashman noticed what was going on, he told Alex to put the magazine away and to get to work. Alex complied, but five minutes later he got out the magazine again. On another day, Alex fell asleep and had to be woken up by his partner. Alex frequently asks to go to the bathroom. Each time Mr. Cashman lets him go.

Mr. Cashman needs to determine the amount of time that Alex spends off-task during class.

Measuring Behavior Level C • Case 1

Background Student: Howard

Age: 8

Grade: 3rd

Scenario Howard is showing significant signs of reading and math difficulty. Ms. Anderson—a first-year teacher—has referred him to the office six times in four months for “insubordination.”

When the bell rings, Ms. Anderson instructs the class to begin working on the math problems on the chalkboard. Instead, Howard begins to talk loudly about the rims on his dad’s car. Another student, Davis, comments, “Aw, your daddy has a hooptie and those rims are wack.” Howard responds, “Well, at least we have a car. I saw you waiting for the bus.” Other students begin to laugh, and Davis tells Howard to shut up. At this time Ms. Anderson intervenes, telling the students to quiet down. She reprimands Howard and Davis, tells them to go sit down, and reminds them of their assignment. She then returns to her desk. Howard and Davis continue to discuss their parents’ cars. After a moment, Ms. Anderson again reprimands them for talking. Howard then sharpens his pencil, gets a new piece of paper, and walks back to his seat using the longest route possible. After about fifteen minutes, the students appear to have finished their math problems and Ms. Anderson begins class. After class, Ms. Anderson looks at Howard’s paper and realizes that he only completed a few questions.

Howard has several behaviors that Ms. Anderson feels are contributing to his incomplete work, but she is most concerned about him starting his assignments when told to do so. So, the next week, Ms. Anderson collects event data on Howard’s appropriate and inappropriate comments and latency data on how long it takes him to begin his work each day (see next page).

! Assignment 1. Do you agree with Ms. Anderson’s data collection choices? Explain your answers. 2. Complete the forms below by calculating the latency and frequency of Howard’s behaviors. Next, analyze

Howard’s data. a. Are Ms. Anderson’s concerns about Howard’s latency behavior justified? Why or why not? b. Are Ms. Anderson’s concerns about Howard’s inappropriate comments justified? Why or why not?

3. Based on the scenario above, do you think there is other information that Ms. Anderson should collect? If so, list the behaviors that she might want to measure and explain possible data collection methods.

Background Student: Rachel

Age: 17

Grade: 11th

Scenario Mr. Smith co-teaches an inclusive biology course at Hamilton High School with Mrs. Patel, a special education teacher. Because the students have a wide range of reading abilities, one of the teachers frequently reads a paragraph from the text aloud and then asks listening comprehension questions. During this question-and-answer period, students are required to raise their hands and wait to be called on.

Rachel, a new transfer student, frequently talks to peers and writes notes to friends during this activity. When she does respond to questions, she blurts out the answer without waiting to be called on. Though her answers are always correct, the teachers are frustrated with her behavior. Mr. Smith reprimands her several times before sending her to the office. Upon being sent to the office for the fourth time, Rachel complained, “You’re always picking on me!” Mr. Smith spent the next two minutes explaining how fair he is with his students. Concerned about this pattern of behavior, Mrs. Patel has collected the following data (see next page).

! Assignment 1. Do you agree with Mrs. Patel’s data collection choices for each target behavior? Explain your answers. 2. Complete the forms below by calculating Rachel’s rate of calling out and her occurences of off-task

Data collection can serve as a way to gather evidence to help improve student behavior. Teachers should choose a data collection method that provides the most accurate picture of student performance in the classroom. When they select a data collection method, teachers can refer to the flowchart below:

Regardless of the data collection system implemented, students sometimes behave differently if they know they are being observed or when a new person is in the classroom. Some ways to reduce this reactivity are to observe other students as well so that the target student does not feel like he or she is being singled out, to practice observing a few times so that the student gets used to the observer before official data collection begins, and to try to be discrete to reduce the likelihood that the student will notice that he or she is being observed.

Measuring Behavior Frequency/Event Recording

What It Is Frequency or event recording is a way to measure the number of times a behavior occurs within a given period.

What the Research and Resources Say • Event recording can be used if the goal is to increase or decrease how often the behavior(s) occur (Special

Connections, n.d.). • Event recording is best for behaviors with a distinct beginning and end (Cooper, Heron, & Heward, 2007). • Event recording has been used in classrooms to measure behaviors such as:

◦ Task initiations and protests to task demands (Dibley & Lim, 1999) ◦ Inappropriate sitting and littering (Wheatley et al, 2009) ◦ Correct and incorrect academic responses (Heckaman, Alber, Hooper & Heward, 1998) ◦ Tardiness (Johnson-Gros, Lyons, & Griffin, 2008)

• Teachers have used event recording to measure their own behaviors, such as: ◦ Praise statements (Kalis, Vannest, & Parker, 2007) ◦ Response opportunities provided to students (Moore, Partin, Robertson, Maggin, Oliver, & Wehby,

2010) • Event recording is best for behaviors that occur with enough time in between to distinguish between the end

of one response and the onset of another (Cooper, Heron, & Heward, 2007).

Tips for Implementation • Comparing event or frequency data across observations allows teachers to determine whether the behavior

is increasing, decreasing, or showing no change. For this reason, it is helpful if the observa-tion periods are the same length.

• To discretely document the number of times a behavior occurs (i.e., the frequency), try one of the following procedures:

◦ Place tally marks on paper. ◦ Put a piece of masking tape on your arm and place tally marks on the tape. ◦ Purchase a small, inexpensive handheld tally counter. ◦ Put a handful of small items such as pennies or paperclips in one pocket and move one item to the

other pocket each time the behavior occurs. Add the items to determine how many times the behavior occurred.

THE

IRIS CENTER

STAR SheetH

H13http://iris.peabody.vanderbilt.edu

• When it is not possible to observe the student’s behavior for the same length of time for each observation period, calculate the rate of the behavior for each observation and compare across observations. To calculate the rate of a behavior, use the following steps.

1. Note the time the observation begins. 2. Record each occurrence of the behavior. 3. Note the time the observation ends. 4. Calculate the length of time for the observation. 5. Calculate the rate by counting the total number of times the behavior occurred and dividing by the

length of the observation.

H

• When using event recording for academic skills, count both correct and incorrect responses for a more complete evaluation of learning. Evaluating only correct responses can be misleading, especially if incorrect responses increase over time or are more frequent than correct responses.

Keep In Mind • The teacher’s actions might influence a student’s behavior. For example, if a teacher asks a student to

respond ten times during one lesson, but only three times during another, the frequency data will reflect that action rather than the student’s behaviors.

• It may be appropriate to count the subcomponents of a complex task instead of the completion of the task itself. For example, if the desired behavior is to complete ten double-digit multiplication problems during independent seat-work, the teacher might give each problem three tally marks—one for completing the ones digit column, one for completing the tens digit column, and one for completing the problem.

• Event recording provides more accurate information than does interval recording (described on Page 18).

Measuring Behavior Interval Recording

H

H What a STAR Sheet is… A STAR (STrategies And Resources) Sheet provides you with a description of a well-researched strategy that can help you solve the case studies in this unit.

What It Is Interval recording is a method of documenting whether a behavior occurred during a brief time periods (e.g., 10 seconds), refered to as intervals. At the end of each of these intervals, the observer records whether or not a behavior has occurred. There are two types of interval recording:

• Whole-interval recording – yields data on the total duration of the behavior. When utilizing whole-interval recording, an observer indicates whether the behavior occurred for the entire interval.

Example: A student worked on an assignment for an entire thirty-second interval.

• Partial-interval recording – yields data on the proportion of the observation period that the behavior occurred. When utilizing partial-interval recording, an observer indicates whether the behavior oc-curred at any point during the time interval.

Example: A student worked on an assignment for fifteen seconds of a thirty-second interval.

What the Research and Resources Say • Interval recording is used for continuous behaviors or for those behaviors whose onset and end are difficult

to distinguish because the behaviors occur at such high rates (Cooper, Heron, & Heward, 2007; Special Connections, n.d.).

16http://iris.peabody.vanderbilt.edu

THE

IRIS CENTER

STAR Sheet H

H17http://iris.peabody.vanderbilt.edu

The table below highlights research using both whole- and partial-interval recording.

Tips for Implementation • Consider using a prompt to signal the beginning and end of intervals, such as:

◦ Audio recording with beeps (headphones should be used!) ◦ Electronic device that vibrates ◦ Cellphone apps

• To use the interval recording method, use the steps outlined below: 1. Schedule the observation period at times during which the behavior is most likely tooccur. Typically,

observations last between ten minutes and an hour, although it is more accu-rate and less burdensome to use shorter periods.

2. Divide the observation period into equal intervals. These intervals are usually between five and fifteen seconds long. a. Whole interval: Record with an “x,” plus sign, or check-mark if the behavior occurred throughout

the duration of the interval (e.g., if using ten-second intervals, the behaviormust last the entire ten seconds). If the behavior did not occur for the entire interval, then record the nonoccurrence of the behavior with a minus sign or 0.

b. Partial interval: Record with an “x,” plus sign, or check-mark if the behavior occurred at any point during the interval (e.g., if using ten-second intervals, the behavior mustoccur at least once during that particular interval). If the behavior did not occur during the interval, record the nonoccurrence of the behavior with a minus sign or 0.

3. Count the number of intervals during which the behavior occurred. Divide this number by the total number of intervals and multiply by 100 to determine the percentage of intervals during which the behavior occurred.

• Only one behavior at a time should be observed when using whole-interval recording, due to the necessity of observing during the entire interval. Multiple behaviors can be observed during partial-interval recording because an observer only has to document whether a behavior occurred at all during an interval.

• If an observer is not sure whether the behavior occurred (e.g., a student walks behind a bookshelf or room divider where he or she cannot be seen), the inability to observe should be documented on the observation form, rather than attempting to guess what is occurring.

• Because whole-interval recording requires the observer’s constant attention, it can be difficult too bserve and record simultaneously. When using whole-interval recording, you might need to alternate intervals during which you observe and record (e.g., observe for ten seconds, record for five second, observe for ten seconds, record for five seconds). This gives you time to record your observation before the next observation interval. (Note: Whole-interval recording is not practical if the teacher is the observer.

Keep In Mind • Interval recording provides an estimate of behavior.

◦ Whole-interval recording typically underestimates the overall duration of the behavior because if a behavior occurs—but not for the entire interval—it is not recorded or documented as occurring.

◦ Partial-interval recording typically overestimates the overall duration and underestimates the rate of the behavior because if a behavior occurs multiple times during an interval, it is still documented as occurring only once.

The graphic below illustrates this tendency.

• If you need an accurate measure of the rate of behavior, event recording should be used. Interval recording does not provide this type of data.

• The shorter the intervals, the more accurate the recording.

Measuring Behavior Duration Recording

What it is… Duration recording is a method of documenting how long a student engages in a specified behavior.

What the Research and Resources Say… • Duration recording is appropriate for behaviors that have a distinct beginning and end or for those that

occur at such high rates that it would be difficult to get an accurate frequency count (e.g., number of taps during pencil-, finger- or toe-tapping) (Alberto & Troutman, 2006; Cooper, Heron, & Heward, 2007).

• The table below highlights research using duration recording.

Tips for Implementation • Consider using a digital stopwatch to increase the accuracy of duration recording. A wall clock or

wristwatch can be used but may not be as accurate. • To use the duration-recording method, follow the steps below:

1. When the behavior begins, start the stopwatch. 2. When the behavior ends, stop the stopwatch. 3. Record the length of time that the behavior occurred. 4. Repeat the above steps until the end of the observation period. 5. Calculate the total duration by adding the duration of each episode during the observation period.

(Note: Some digital stopwatches will automatically calculate the total time.)

• Video or audio recordings may be used to collect duration data—and viewed or listened to later—if it is impractical to collect duration data during class.

• Consider collecting frequency data for the target behavior in combination with duration data to provide a more accurate picture of the student’s behavior. It is quite different for a student to engage in five episodes of screaming that last ten minutes each than to engage in one episode that lasts fifty-five minutes.

Keep In Mind • You might also want to report duration data in terms of the average duration per observation period (total

duration / number of occurrences) if the observation period is consistent. For example, the stu-dent has five minutes at the end of a class each day to work on his homework. The student works on his homework for a total of fifteen minutes across five days. To calculate the average duration the student worked on his homework, divide fifteen minutes by five days. The average is three minutes.

• If the observation periods vary in length (e.g., the class has twenty minutes in the library the first week of the month and fifteen minutes the second week of the month), the percentage of time the student engaged in the behavior can be calculated by dividing the total minutes of the behavior’s duration (e.g., 20 minutes) by the number of minutes in the observation period (e.g., 60 minutes) and multiply-ing by 100.

Measuring Behavior Latency Recording

H

H What a STAR Sheet is… A STAR (STrategies And Resources) Sheet provides you with a description of a well-researched strategy that can help you solve the case studies in this unit.

What It Is Latency recording is a method of documenting the time between when a direction is given and when the student complies.

What the Research and Resources Say • Latency recording is appropriate when the teacher wants to measure how much time passes between when

an instruction, cue, or prompt is provided and the behavior begins or ends (Cooper, Heron, & Heward, 2007; Special Connections, n.d.).

• The table below highlights research using latency recording.

Tips for Implementation • Consider using a digital stopwatch to increase the accuracy of latency recording. A wall clock or wrist

watch can be used if a digital stopwatch is unavailable. • To use the latency recording method, follow the steps below:

1. Start the stopwatch when the prompt, directive, or instruction is provided. 2. Stop the stopwatch when student complies. 3. Record the number of seconds or minutes that elapsed between the end of the direction and the onset

of the compliance. 4. Repeat the above steps until the end of the observation period. 5. Calculate the average latency of the behavior by dividing the total latency (e.g., 60 seconds) by the

number of occurences (e.g., 3 directions).
