There is much research conducted on training teachers to use the evidence-based teaching strategies known as system of least prompts. However, there is little research conducted on using a modified system of least prompt. This study examined the fidelity of implementation by two early childhood teachers using a modified system of least prompts with preschool aged children. A multiple-probe design across participants was used to determine the effect of fidelity of implementation of a modified system of least prompts strategy on the level of on-task student engagement. The results showed that early childhood teachers could implement the modified teaching strategy with fidelity while also increasing the level of on-task engagement.

The purpose of this study was to examine the effectiveness of using the system of least prompts and concrete representations to teach students with moderate and severe disabilities (MSD) to solve simple linear equations. A multiple-probe (days) across participants, single case research design was used to evaluate the effectiveness of task analytic instruction along with concrete representation on teaching students with MSD to solve algebraic equations. The results showed the system of least prompts and concrete representations were effective in teaching students with MSD to solve simple linear equations.

The purpose of the study was to evaluate the effects of a system of least prompts procedure and use of a graphic organizer to teach an academic standard for elementary students with moderate intellectual disabilities. A multiple probe (days) across participants design was used to evaluate the effectiveness of using a system of least prompts and a graphic organizer to teach students how to compare two characters from adapted text. The results showed a system of least prompts and the use of graphic organizer was effective in teaching an academic standard for students with moderate intellectual disabilities.

This study examined the fidelity of implementation by four Head Start teachers using the teaching strategies of constant time delay, enhanced milieu teaching, and system of least prompts with children with and without disabilities in an inclusive early childhood setting. The teachers worked with the researcher to determine appropriate skills to target for each teaching strategy. A multiple probe across behaviors design replicated across four teachers was used to determine the effects of teachers’ fidelity of implementation of evidence-based teaching strategies. The results showed that Head Start teachers could implement systematic teaching strategies with fidelity. The study also examined if children with and without disabilities can make progress towards their target skills. The results showed that children were able to make progress towards their target skills.

For students with physical and health disabilities, the development of self-advocacy skills is critical to their future success. Characteristics that may inhibit the development of self-advocacy skills in this population include reliance on others for assistance across multiple areas requiring physical abilities, deficits in communication skills, and the development of learned helplessness. Instruction in self-advocacy is needed for this population of students in order to maximize future success and decrease learned helplessness (Angell, Stoner, and Fulk, 2010; Macdonald & Block, 2005; Roberts, 2007). For this study, the researcher provided instruction to four elementary age students with physical disabilities who exhibited characteristics of learned helplessness, including ineffective initiation of requests. Students used speech, sign, or gestures as their primary form of communication, and were able to use this form of communication as a reliable means of response during typical classroom activities, including social interactions and when responding to questions. When they needed to initiate a request for required materials during classroom activities, they made no response, ineffectively gestured, or made unrelated comments when prompted to complete an activity. Students who initiated requests ≤ 50% of presented opportunities were eligible to participate in this study. The intervention consisted of combined use of environmental arrangement and the system of least prompts in a multiprobe multiple baseline across participants design. Environmental arrangement strategies included missing materials or materials that were out of reach. The system of least prompts involved the following levels of prompting: (a) independent, (b) verbal – restatement of direction, (c) indirect verbal, and (d) verbal/model. Analysis of the data indicated that three of the four students increased their effective initiation of requests during intervention, and generalized this skill to new materials and novel settings. The fourth student exhibited noncompliant behaviors that interfered with his ability to reach criteria during intervention. These results support the effectiveness of this intervention in decreasing learned helplessness and increasing the self-advocacy skill of initiating requests with students with physical disabilities who have no interfering behaviors.

Although household product, such as pharmaceuticals and cleaning chemicals, are part of a child’s everyday life, accidental poisonings can occur as a result of ingestion. Children diagnosed with developmental disabilities are even more susceptible to being injured when they come into contact with these poisonous agents. Behavioral approaches have been used extensively to teach safety skills to children with disabilities. However, those that targeted poison prevention skills required additional methods that were more intrusive for the child to acquire the skills. Thus, the purpose of this study was to evaluate the efficacy of a modified behavioral skills training package that incorporates a system of least prompts. Results showed that BST and system of least prompts increased poison prevention skills for all three participants and the skills maintained at follow-up.

The purpose of this study was to determine if there was a functional relation between a peer-delivered modified system of least prompts procedure (SLP) and an increase in level and trend of performance on finding the area of polygons or finding the volume of cylinders, spheres, and cones, and could the peer tutor reliably implement the modified SLP procedure with middle school students with mild to severe disabilities. A multiple probe days across participants design was used. Results from this study show that there was a functional relation across students in which students were able to make progress on academic math skills when taught by a peer tutor using the modified SLP procedure. The peer tutor was able to reliably implement the procedure to multiple students. Limitations and implications for practice are discussed.

We are currently in an era of accountability, so the need for measuring fidelity of implementation is gaining attention. However, there is little research in the area of fidelity of implementation and an inclusive early childhood classroom. In addition, most of the research is conducted using teachers. This study examined the fidelity of implementation by two teaching assistants using the teaching strategies of time delay and system of least prompts with children with and without disabilities in an inclusive early childhood setting. A multiple-probe design with conditions across two behaviors and across two participants design was used to determine the effects of teaching assistants’ fidelity of implementation of evidence-based teaching strategies. Also a multiple probe across two behaviors, replicated across children was used. Most importantly, the results showed that teaching assistants could implement systematic teaching strategies with fidelity. Secondly, the children were able to make progress towards their target skills.

The purpose of this study was to examine the effects of training peer models to implement the system of least prompts and model augmentative and alternative communication (AAC) on expressive language in children with developmental delays. Using a multiple probe across participants design, 4 students with developmental delays were trained to use a language output app on the iPad to communicate five common phrases. Results for 3 participants indicated a functional relation between the peer modeling and expressive language. One student did not complete the intervention due to excessive absences. In most cases, students increased verbal language. Two participants made progress with the intervention as it was planned. One student needed for the intervention to be adapted, then progressed. All three students were able to maintain these language skills. Future research should be carried out with students with different disabilities, older students, and further studies with preschool-aged students.

Students with disabilities often face difficulty throughout their lives. One of these common challenges for students with severe disabilities is they often struggle with routine skills — for example, significant time spent helping students transition to activities throughout the day. The student's performance to complete required daily school routines increased when the researcher applied the picture activity schedules. Also, one strategy to enable students with disabilities to increase independence is through assistive technology. Therefore, many studies support the use of technology-based visual supports to teach daily school routines. Teachers increasingly have started to adopt an electronic visual activity schedule (eVAS) as a means to provide clear and consistent support for students with disabilities. Although the above studies are positive, there is still a need to more fully examine the various outcomes of eVAS. Therefore, this study is to investigate the effects of using eVAS (i.e., FIRST THEN application) on the latency period that the student spends for checking the schedule independently and prompts needed to transition throughout the day. Also, the value that the teacher and student place on the use of an eVAS to teach daily life and school routines instead of using typical instruction (e.g., traditional visual schedule), and the student’s ability to generalize the use of the eVAS across instructors and materials (display). The participant was a 10-year-old male in the fifth grade with intellectual disability and autism. This study was conducted in an intermediate school in the southeastern United States. An ABAB single case design was used to investigate the effects of the app. The dependent variables (DV) included: 1) The percent of independent correct responding to the natural cue “timer went off, or the teacher said: “Time to Switch”; 2) The amount of time the participant took to respond to the natural cue and check a schedule. The independent variable (IV) was applying the system of least prompts (SLP) along with the First Then application on iPad. Both DV and IV were collected five sessions in five days, during the transition period between activities in each baseline, intervention, maintenance, and generalization phases. The second observer recorded 25% of the data collection of the inter-observer agreement and procedural fidelity. By the end of the study, the social validity survey was provided one for the teacher and another one for the participant. The result indicated a functional relation between DV and the IV. Also, the limitation and the suggestion for future research were discussed. In conclusion, this study extended the result of prior studies by emphasizing the effectiveness of using the eVAS with students to independently complete the routine skills and applying SLP to give the student the opportunity to do the task with less prompts. The study will guide teachers use of such support tool and apply the intervention in the classroom with students with disabilities.
