An ecological approach to evaluating a special education program.
DeSouza, Eros Ramos ; Sivewright, David
About fifteen percent of all children show mild behavioral problems,
and about seven percent show moderate to severe disorders (Cotler,
1986). However, not enough has been done to treat or prevent these
problems (Levine & Perkins, 1987). Even less has been done to
evaluate existing treatment programs (Felner et al., 1983).
Historically, evaluations of special education programs have examined
deficits in student performance or capability, focusing on organismic,
cognitive, or behavioral problems such as brain damage, perception
difficulties, learning disabilities, and lack of motivation (Greenwood
& Carta, 1987). Although these individual-level factors are
important, they may lead to premature labeling and victimization. For
example, young children have been disproportionately labeled as
socially, cognitively, or behaviorally "deficient" (Drabman,
Tarnowski, & Kelly, 1987). Hence, teachers may interact with
students as if they were a bundle of deficiencies (labels), rather than
considering settings and systems as part of the problem or solution.
Further, children who live in economically and educationally
impoverished environments are at higher risk for a number of negative
educational and social-emotional outcomes (Brand, Dubois, & Felner,
1990). Thus, ecological variables need to be investigated because they
can either influence the onset of behavioral problems (Heller, 1990) or
positively affect learning behaviors (Greenwood & Carta, 1987).
The interaction of academic materials (static features of the
environment) with students and teachers (dynamic features of the
environment) forms classroom ecologies. In an effort to describe these
environments, the ecobehavioral approach to program evaluation has
emerged in the field of applied behavior analysis. This approach links
ecological factors, which may facilitate or hinder students'
academic performance, with program outcomes (Greenwood & Carta,
1987). Thus, the ecobehavioral approach is useful for providing
important information about the classroom climate and the effects of
interventions (Greenwood et al., 1985).
One indication of positive effects of special education programs is
that students engage more often in academic-related behaviors than in
disruptive ones. For example, there is evidence that active classroom
behaviors (e.g., asking or answering questions, reading, writing) are
correlates of academic achievement, whereas disruptive behaviors are not
(Rosenshine & Stevens, 1986). As Becker (1977) states, "at
risk" students need instruction that enables them to perform
academically at accelerated rates. In fact, these students need to learn
more and faster just to obtain achievement comparable to more advantaged
students. Therefore, the purpose of the present study was to examine
ecological and student behavior variables that may be linked to the
objectives of the program--increasing appropriate classroom behaviors
and decreasing inappropriate ones. Here, the ecobehavioral approach was
modified in order to describe patterns in the whole classroom rather
than patterns in one student, as originally proposed by Greenwood and
Carta (1987).
METHOD
Setting and Program Description
The setting was a private residential treatment center located in a
large midwestern city. The center serves behaviorally disturbed
adolescent males between the ages of 12 and 18 years. For those whose
educational needs cannot be met in a regular school setting, the center
offers a special education program. This program aims to alleviate
behavioral difficulties that impede academic performance, such as
chronic task incompletion, acting out, behavior problems, or social
interaction conflicts. Two important objectives are to increase
academic-related performance and decrease disruptive behaviors in the
classroom.
Participants
At the time the study was conducted, there were 84 emotionally
disturbed adolescent males in the special education program. Their
average age was 15 years, and most of them were Caucasian (90%). The
majority of the boys (71%) were diagnosed with disruptive disorders
(American Psychiatric Association, 1987).
Materials
Ecobehavioral data were collected using the Code for Instructional
Structure and Student Academic Response (CISSAR; Stanley &
Greenwood, 1981). CISSAR assesses the occurrence of ecological events
and student behavior variables that are closely associated in time. A
brief description of the CISSAR codes used in this study appears in
Table 1.
In order to permit additive frequencies, the CISSAR codes were
designed to be mutually exclusive. Observers concurrently assessed the
occurrence of one ecological event and one student behavior. This type
of assessment allowed for the creation of three hierarchical composites
from the student behavior variables: (1) active academic responses,
including writing, engaging in task participation, reading aloud,
talking about academic topics, and reading silently; (2) passive
responses, including attending to task (not actively engaged) and other
appropriate behaviors (not academically related); and (3) competing
responses (behaviors that compete with academic ones), including looking
around, being disruptive, or exhibiting other inappropriate behaviors.
Procedure
Observational data were collected using a momentary time sampling
procedure. This type of observation is analogous to taking a photograph
of the instructional process at that instant. A 15-second time interval
was used.
Before collecting usable data, observers had to become thoroughly
familiar with the CISSAR codes during a three-week training period. At
its completion, these observers achieved 98% agreement in three
consecutive 20-minute observations. Interrater reliability was computed
by comparing the records of two observers, who simultaneously, but
independently, recorded the same phenomena. If the accounts agreed
exactly or disagreed by no more than plus or minus one tally, agreement
was recorded for the cell.
Classroom observations were then randomly scheduled in math, English,
and social studies courses ("core classes" that all students
were required to take) during the academic semester. For each
observation, TABULAR DATA OMITTED one observer recorded the
instructional process for a 20-minute block, unless there was a
prolonged interruption, which resulted in a new observational block. At
the end of each 15-second interval, the observer targeted one student
and coded both the ecological event and student behavior occurring at
that precise moment. At the end of the next interval, the observer
targeted another student and recorded the ecological event and behavior
he was engaged in. Each student was targeted in a clockwise manner until
all students in the classroom had been observed (classroom size ranged
from 4 to 12 students, with an average of 10 per room). The observer
then repeated the cycle. Thus, inferences could be made about the
relative frequency of occurrence of each variable for the entire class.
In order to minimize observer bias or drift, reliability checks were
conducted every three weeks for the duration of the semester. Observers
maintained an excellent level of interrater reliability (90% or above).
RESULTS
The results of 4,612 samples of behavior from nearly 20 hours of
direct classroom observation are presented in Tables 2 and 3.
Percentages for the response composites and the student behavior
variables appear in Table 2. Active academic responses comprised 56% of
observed time, with reading silently (29%) and writing (16%) being the
most frequent behaviors. Passive responses accounted for 36% of observed
time, with attending to task (29%) being the most frequent behavior.
Competing responses made up only 9% of observed time, with looking
around (6%) being the most frequent behavior in this category.
The ecobehavioral data also allowed for determination of conditional
probabilities, which are estimations of the probability of particular
behaviors given the presence of specific materials (physical aspects) or
groups (types of relationships between persons in groups). The
conditional probabilities are shown in Table 3. The most interesting of
these conditional probabilities concerns competing responses. Although
student-student discussion (Ssd) occurred at a very low rate (5%), it
was during this time that students engaged in the highest level of other
inappropriate (Oi) behaviors (27%). Another interesting finding is that
writing and reading occurred almost exclusively during independent tasks
(e.g., when using readers, workbooks, worksheets, paper and pencil, and
other media), rather than during more interactive lessons, such as
discussions with the teacher or peers.

DISCUSSION
The ecobehavioral data reveal that these students spent over half of
the observed time engaged in active academic responses (56%) and only 9%
of the time in competing responses (inappropriate behaviors). Although
these findings indicate that the program apparently accomplished its
objectives (i.e., to increase appropriate and decrease competing
behaviors), there are intriguing ecological implications. First, most of
the active academic behaviors observed reflect engagement in busywork (static aspects of the classroom environment). For example, although
reading silently (29%) and writing (16%) comprised the most common forms
of active responding, students were working by themselves rather than
engaging in interactive lessons, such as discussions with the teacher
and peers (dynamic features of the environment).
Second, these students engaged in passive responding over one-third
of the time (36%). They spent a considerable amount of time (29%)
appearing to be paying attention in class (i.e., attending to task).
During that time, they spent 87% of the time appearing to be listening
to their teacher lecturing. That is, they were oriented toward the
teacher, but made no active responses (e.g., asking questions) that
would demonstrate comprehension or mastery. Thus, the data suggest that
these students may act as passive responders to external, perhaps
uninteresting, stimuli.
Third, these students were often restricted to highly structured
classroom activities. Such activities may provide few opportunities for
students to engage in challenging work. The literature indicates that
highly structured activities do little to enhance students'
abilities to think critically, weigh evidence, and develop independent
judgment (Dreeben & Gamoran, 1986; Greenwood, Delquadri, & Hall,
1984; Longshore & Prager, 1985). In a similar vein, there is
evidence that controlling environments often have a deleterious effect
on motivation and learning (Deci & Ryan, 1985).
In summary, these students may benefit from challenging interactions
that promote learning, such as discussions with teachers and peers (Deci
& Ryan, 1985). Specifically, they may advance faster if they receive
immediate feedback on their tasks (e.g., by asking questions or talking
about academic matters, rather than by engaging in busywork).
CONCLUSION
After disseminating these findings to administrators and teachers,
those in charge of the program have made attempts to improve it. For
example, teachers have been instructed to increase active learning
responses by providing students with more challenging tasks and greater
opportunities for immediate feedback.
There are costs as well as benefits involved in this modified version
of the ecobehavioral approach. Although generalization is increased by
assessing all students in the classroom, it is difficult to determine
the validity of this approach from a single study. Thus, more
experimental validation is warranted.
