Small-group instruction for students with learning disabilities: observational and incidental learning
Constant time delay, a near errorless learning method, effectively taught multisyllabic vocabulary to fifth graders with learning disabilities, achieving high accuracy with minimal errors.
Area of Science:
- Special Education
- Applied Behavior Analysis
- Educational Psychology
Background:
- Learning disabilities present challenges in vocabulary acquisition.
- Effective instructional strategies are crucial for students with learning disabilities.
- Small-group instruction can be an efficient delivery model.
Purpose of the Study:
- To evaluate the effectiveness and efficiency of the constant time delay procedure.
- To assess its utility in a small-group instructional setting.
- To determine its impact on vocabulary recognition, spelling, and definition for students with learning disabilities.
Main Methods:
- A multiple-probe design across behaviors (word sets) was employed.
- Three fifth-grade students with learning disabilities participated.
- Constant time delay (a near errorless learning procedure) was used to teach multisyllabic vocabulary.
Main Results:
- The constant time delay procedure was reliably implemented.
- All students achieved criterion-level performance.
- Extremely low error percentages were observed across all students.
Conclusions:
- Constant time delay is an effective and efficient strategy for teaching multisyllabic vocabulary.
- The procedure is suitable for small-group instruction for students with learning disabilities.
- This method facilitates high levels of accuracy and minimal errors in vocabulary learning.

Naturalistic Observations
Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...
