The field of special education's focus on moderate and severe disabilities (MSD) has undergone a number of changes in the past five decades. Some have been philosophical, some based on research, some based on mandated practices through U.S. law, and some based on the development of better technologies. While pioneers in the field first established…

Within the context of a multiple baseline design, the researchers in this investigation used a constant time delay (CTD) procedure to teach two classroom support personnel (i.e., paraprofessional, peer tutor) to use a simultaneous prompting (SP) procedure when teaching a high school student with a moderate intellectual disability to (a) identify…

In this study, we used an instructional package consisting of a constant time delay procedure with multiple exemplars to teach five elementary students with moderate intellectual disability to identify geometric shapes listed in their state's core content standards and included on their state's alternate assessment. In addition, we included four…

Distance education services are an effective way to meet the needs of students with disabilities, but few special educators get the preparation they need to conduct high-quality instruction remotely. All the fundamentals are in this one-of-a-kind guide, the first dedicated book on distance learning for special educators. With contributions from…

Response-prompting procedures are a form of systematic direct instruction based on the principles of ABA. Researchers have identified six specific and distinct response-prompting procedures for teaching both academic and functional skills: (1) graduated guidance; (2) most-to-least prompting; (3) system of least prompts; (4) progressive time delay;…

Preliminary research shows promise for the use of supported electronic text (eText) combined with explicit instruction in facilitating comprehension for students with intellectual disability. Researchers used a multiple probe across participants design to evaluate effects of supported eText including explicit instruction on measures of vocabulary,…

An important part of quality of life for people with moderate and severe disabilities (MSDs) is being involved in extracurricular and community activities. However, volunteers, who may not have experience with including people with MSDs, lead most community activities. The purpose of this study was to demonstrate the effectiveness of teacher…

This investigation focused on the systematic instruction of a science skill from the core content standards in accordance with the Kentucky Alternate Assessment for students with moderate and severe disabilities (MSD). Specifically, this study examined the effectiveness of using a constant time delay procedure with multiple exemplars in teaching…

To ensure the best outcomes for students with moderate and severe disabilities, K-12 educators need to understand what constitutes good instructional practices and how to apply them in any classroom, with any curriculum. All the how-to guidance they need is in this accessible text on systematic instruction, a highly effective teaching approach…

This investigation compared the effectiveness and efficiency of constant time delay (CTD) and simultaneous prompting (SP) procedures in teaching discrete social studies facts to 4 high school students with learning and behavior disorders using an adapted alternating treatments design nested within a multiple probe design. The results indicated…

Special education teachers often search for effective strategies to teach a variety of skills to students with moderate to severe disabilities through small group instruction. The investigators examined the acquisition of academic skills as well as chained and discrete tasks presented as nontargeted information by a small group of students with…

Many students identified as having moderate and severe disabilities (MSD) benefit from a curriculum that includes instruction on the functional skills that they will need to successfully transition to adulthood. In particular, this includes students with cognitive disabilities who are most likely to qualify in the 1% who are eligible for the…

In this investigation, the acquisition of both functional and core content sight words was compared as replicated across three formats: direct massed trial instruction in a special education resource room, direct distributed trial instruction in a general education classroom, and embedded distributed trial instruction in a general education…

This article reviews current literature on small group instruction with moderately to severely disabled students, discussing such components as group size, homogeneous/heterogeneous groupings, task selection, instructional strategies, attentional cues, presentation of the discriminative stimulus, trial presentation, choral and individual…

This study evaluated the effectiveness of the constant time delay procedure, while comparing the efficiency of using teacher-selected and student-selected material prompts, in teaching multiplication facts to 4 male students with learning disabilities (ages 9 to 13). Results indicated that the time delay procedure was most efficient when students…
