Single subject research has long been employed to evaluate intervention effectiveness with students with learning or behavioral disabilities. Typically, the results of single subject research are presented on graphic displays and analyzed by a method of visual inspection, in which analysts simultaneously consider such data elements as level change, slope change, and variability in baseline and treatment data. However, over the years several concerns regarding visual inspection have emerged, including relatively low inter-rater reliabilities. This chapter reviews the arguments in favor of visual inspection as an analytic tool, and also summarizes the arguments favoring statistical analysis of single case data. The use of randomization tests is recommended, and an example is provided of its use in research with students with learning and behavioral disorders.

Children with autism spectrum disorder (ASD) face difficulty with educational attainment because of to their inability to interact with others. One intervention that is used to increase social skills in individuals with ASD is social stories. This study aimed at exploring the impact of digital social stories in improving social skills of two students with ASD in the UAE.

An experimental AB single-subject study was conducted to investigate the impact of digital social stories on nonverbal communication, targeting two specific behaviors: raising hands before leaving one’s seat (TB1) and playing and sharing toys with peers (TB2). Two digital social stories (DSS1 and DSS2) were developed for the purpose of this study and transformed using a digital platform to be displayed on an iPad (tablet).

This study involved two male participants with ASD (10 and 11 years old). Participant one demonstrated improvement in TB1 (mean of 1.11) because of DSS1 in the intervention phase. Participant two demonstrated improvement of 18% in TB2 ( mean of 0.18) as a result of DSS2 in the intervention phase.

Both students that participated in the study showed a positive change in their target behaviors during the intervention phase intervention at different levels. Using an ABA study design would have been stronger in establishing a more valid causal relation in this single-subject design study. However, due the COVID-19 closures and curfews, the researchers had to switch to the AB design.

This study demonstrated how social stories had a positive impact on ASD social skills. Further, it indicated the potential effectiveness of using digital social stories to reduce undesirable behaviors or increase a desirable behaviors in children who have ASD.

Individuals with severe speech and language impairment as a result of chronic severe Broca's aphasia may rely on non‐speech communication aids to augment or replace speech. These aids include speech‐generating devices and graphic symbol software programs that produce synthetic speech upon activation. Previous research has indicated that individuals with chronic severe Broca's aphasia are able to identify, manipulate, and combine graphic symbols to produce simple phrases and sentences. The primary aim of this study is to evaluate the ability of three individuals with chronic severe Broca's aphasia to produce graphic symbol sentences of varying levels of complexity using a speech generating device. A single‐subject multiple‐baseline design across behaviours replicated across three participants was used to assess the effect of AAC intervention on the production of sentences using graphic symbols. Findings indicated that individuals with chronic severe Broca's aphasia were able to combine graphic symbols to produce sentences of varying levels of complexity. The results of this study suggest that technologically‐based AAC intervention approaches can be effective in facilitating communication for individuals with chronic severe Broca's aphasia. The overall findings are discussed in terms of clinical and public policy implications.

With the national emphasis on the use of evidence-based practices in educational settings, intervention research within the field of special education is being scrutinized. No Child Left Behind (NCLB) has defined evidence-based practices primarily by research that is based on quantitative, experimental designs (i.e., RCT). Although the use of appropriate experimental designs has an important place in educational research, defining evidence-based practices based on research design alone is limiting. One critical aspect of research that has not received much attention is the importance of rigorous and precise measurement and systematic replication of research findings. The purpose of this chapter is to review issues surrounding measurement and its effect on validity in intervention research in the field of behavioral disorders. Specifically, we discuss how more rigorous measurement can positively influence the internal, external, construct, and social validity of research findings. A review of current trends in behavioral disorders intervention research is discussed as well as implications for future research.

The purpose of this paper is to report a pilot experiment to test if multi-player online video games could provide a measurable cognitive therapeutic benefit for brain-injured people.

Single-subject research design with n=3 brain-injured participants. Four alternating intervention and non-intervention weeks. Battery of cognitive tests taken at the start of the experiment and at the end of each week.

Widely varying results with large standard deviation overall.

The experimental design was heavily reliant on multiple participants logging in at the same time. Server logs showed that this happened relatively rarely.

Implications for the next iteration of the experiment are to refine the game design to avoid the need to synchronise the participants. The findings presented may be of practical use to other researchers in this area.

Acquired brain injury has been described as an epidemic, and is rising, with stroke being a leading cause. Traumatic brain injury (e.g. due to road traffic accident) has increasing prevalence in low-middle income countries. This research aims to provide a form of therapy to people for whom physical access to rehabilitation services is limited.

The use of multi-player online video games as rehabilitation is a relatively unexplored area. A positive result in an experiment of this nature would indicate the potential for a new, complimentary form of cognitive therapy for brain-injured people.

Federal education laws increasingly seem to expect educational research to follow the same processes, approaches, and designs as all scientific research. Scientific inquiries typically are based on empiricism, seen as methodical and producing results that are reliable and generalizable, all of which are appealing when examining educational approaches (National Research Council, 2002). The implementation of scientific inquiry uses experimental conditions, comparison of control groups to groups who received the educational intervention, and clearly measurable outcomes. Experimental conditions require random assignment, which means that participants are just as likely to be selected for the control condition as they are for the experimental/intervention condition. In most educational settings, research rarely achieves random assignment of participants to control and experimental conditions because students are grouped into classrooms with teachers who have different teaching styles, communication styles, and relationships with individual students (Odom et al., 2005).

The purpose of this paper is to present the results of a pilot trial, investigating the accessibility provided by a tablet computer (Apple iPad) to individuals with visual impairment. The study was designed around an N-of-1 randomised controlled trial (RCT), which was replicated for 12 participants. It served as an opportunity to evaluate the use N-of-1 trials in studies involving people who are visually impaired.

The study centred round an N-of-1 RCT, comparing the accessibility provided by control equipment (Windows computer) against the intervention equipment (Apple iPad). Twelve participants conducted six tests on the equipment as per randomisation, followed by a quantitative-based evaluation and short interviews.

One-sided individual randomisation tests showed a significant result for overall satisfaction in favour of the tablet at the 0.05 significance level for seven of the participants. Participants identified several strengths of the iPad in helping a partially sighted user in accessing the internet: inbuilt zoom and magnification options; increased control as a result of the touch screen; and accessibility tools being built into the operating system. The main limitation suggested was the way the zoom function operates by enlarging the onscreen keyboard. This caused difficulties for those with more severe visual impairments using this function in inputting text.

There has been limited research to substantiate positive reviews of the tablet computer for low-vision users. The results of this pilot study gives evidence in support of these potential benefits, and demonstrates the importance of a more thorough investigation.

In this chapter, we examine the current research on how technology is applied to benefit students with emotional and/or behavioral disorders (EBD). First, we describe the iterative yet unpredictable nature of technological innovation to suggest that incremental successes are qualified by the creation of often unforeseen consequences. We then identify commonly used nonelectronic technologies in education to emphasize that the hoped-for advances in electronic technology have failed to deliver on their decades-old promise of educational revolution. We continue with our review of the literature on empirical studies examining how technology is used to support students with EBD. These findings indicate that the research design primarily employed in this field is single-subject. Examples of specific findings include web-based graphic organizers for student writing, virtual self-modeling for targeting student behaviors, and virtual coaching for teachers of students with EBD. We conclude by reviewing how leaders in the field of special education predict the field will change in the future. Overall, with an increased emphasis on research accessibility and practitioner-validated knowledge, and advances in neuroscience and artificial technologies, practitioners may hold a more central role to the creation and dissemination of knowledge.

Research has documented post-school outcomes for students with emotional and behavioral disabilities and learning disabilities continue to be poor. To improve student outcomes for these populations, research has recommended implementing evidence-based practices and predictors in the classroom. The purpose of this chapter is to identify evidence-based practices and predictors targeted for students with emotional and behavioral disorders and learning disabilities in the area of secondary transition. We identify and briefly describe 12 evidence-based practices and 14 evidence-based predictors for students with emotional and behavioral disorders and learning disabilities. Implications for practice and suggestions for future research are also discussed.

Autism spectrum disorder (ASD) refers to a group of complex neurodevelopmental disorders characterized by repetitive and characteristic patterns of behavior and difficulties with social communication and interaction. Puberty is an important period for teenagers with ASD. The purpose of this study was to investigate the effect of educational program on increasing social skills (SS) and sexual knowledge (SK) in adolescent boys with high-functioning autism (HFA) disorder.

This study was conducted using a single-subject design. Participants were three boys diagnosed with HFA disorder, selected using purposive sampling. The social skills improvement system scale and the sexual knowledge questionnaire were used to measure SS and SK. The training program consisted of 49 sessions.

Results showed that, given the comparison of scores before and after the intervention, the training program was effective in improving SS and SK.

With regard to the importance of puberty, training programs for parents and adolescents play an effective role in increasing SS and SK of adolescents with HFA disorder.
