Individuals with an intellectual and developmental disability often require support in completing daily sociological and physiological activities. Therefore, helping individuals who are impacted by these disabilities to acquire these skills is critical to their success to live independently as adults.
avail® is an educational tool that utilizes the principles of Applied Behavioural Analysis (ABA), Video Modelling and other prompting approaches. Providing a research-based personalized programme at the fingertips of individuals with disabilities, support staff, parents, and educators, across the globe.
avail® has been developed from research and professional experience in teaching independent skills, below are some research papers and links that encompasses elements featured within the avail™ system.
Applied Behavioural Analysis
The Applied Behavioural Analysis (ABA) focuses on the principles that explain how learning takes place. Jacobson, J.W. (2000) reported that as a whole, ABA has the best-documented outcome data supporting their approach as compared with other methods”.
avail® utilizes key strategies within the ABA, specifically, task analysis, chaining, prompt-fading, and positive reinforcement.
Prompts are often defined as “artificial” stimuli that are presented immediately before or after the stimuli that will eventually cue the learner to display the targeted behavior at the appropriate time or circumstance.
Prompts can be “instructions, gestures, demonstrations, touch or other things that we arrange or do” to increase the likelihood that individuals will make the right response (McClannahan &Krantz, 1999).
Video Modelling derives from the work of Albert Bandura and his concept of social learning theory (Bellini & Akullian, 2007; Bellini, S., & Akullian, J. (2007). He stated that children learn many skills by watching other people perform the skills and then imitating the behaviours. As early as the 1960s, Bandura suggested that watching televised models was intrinsically motivating and had a strong ability to hold one’s attention. He found that new behaviours could be learned from televised models whether or not extra incentives were provided.
In the past, bulky camcorders, VCRs, and televisions were needed to produce and playback videos. Now with advances in technology, this is available using smart devices (Christine Meister & Joyce Salls, (2015).
Picture based supports are often used to create picture schedules to create an understanding of a person’s daily events and improving on-task behavior (Bryan & Gast, 2000; Spriggs, Gast, & Ayers,2007)
Pictures can be used as a means of prompting individual children to initiate and completes tasks. Such prompting systems, use pictures to depict a step in a chained response task analysis, shows a finished product or the finished location. Using pictures as a reference has been found to aid individuals to complete difficult tasks such as assembling furniture. (Linda Mechling, 2007). Picture schedules have been documented as beneficial within a working environment for people with intellectual disabilities as reported by Carson, Gast & Ayres (2008). The use of visual supports can also aid students with ASD to be incorporated into “an inclusion model”. (Bucalos, Julie Iberer, 2013)
Audio/ Verbal prompts
A review of 268 Applied Behaviour Analysis journal articles identified that verbal prompts are the most commonly reported auxiliary cues (G.S.MacDuff, 1999). These verbal prompts can also be delivered through technology. One study noted how students would listen to pre-recorded instructions on tapes and complete steps that corresponding to steps of task analysis. Two studies noted that audio prompts effectively cued students to continue working and completing employment-related tasks (Briggst et al., 1990; Davis, Brady, Williams, & Burta, 1992). This use of audio prompting on a mobile device was further documented as an aid by Davies, Stock, & Wehmeyer (2002).
While the above teaching strategies focus on creating prompts, a key element is the process of fading back prompts. When creating a prompting aid, we must envision how we can fade out the prompt or reach a level whereby the individual is using the least amount of prompts possible.
Prompt fading is defined as the systematic reduction of a prompt until it is eliminated or redefined as an integrated part of the task, promotes generalization and maintenance of skills. Most-to-least prompting is a common prompt fading procedure used to master new skills. This involved the learner receiving whatever prompt they needed to successfully perform a new skill when instructions begin (Cooper,1987a). Over success teaching, repetition and assessment, the amount of assistance is gradually reduced until no prompts are provided.
In order to reduce prompts, an assessment must be completed to note if learning has occurred. avail® has a built-in guide, that enables assessments and then assists in reducing prompts using Prompting Hierarchy guidelines.
Use of technology in teaching:
The innovation of iPads and smart devices has provided new opportunities for learning and communication for individuals with disabilities. Smart devices are more accessible than traditional PC or laptops, and the individuals enjoy their predictable responses and engaging apps.
It has been identified that individuals with Intellectual Disabilities and ASD can not only achieve significant skill acquisition when taught using mobile technologies but may also rather have the instruction delivered through a mobile device (Shane & Albert, 2008).
This was also supported by Gentry, Wallace, Kvarfodt, and Lynch (2010), they suggested that students demonstrated statistically significant improvement and increased satisfaction in performing daily skills when using the iPods. They also found that students with ASD were easily able to learn using these devices.
Comparison to live Modelling (adult directed/1:1 Modelling):
Adult directed live modelling is a commonly used teaching approach to show an individual how to complete a task or behaviour, where the adult would demonstrate the desired behaviour and allow the child to repeat. (Linda Darling-Hammond et al., 2019)
Charlop-Christy, Le, and Freeman (2000) found that video modelling resulted in quicker rates of skill acquisition and increased generalisation as compared to live modelling. Video modelling also appears to be a more efficient method for teaching skills as it requires less time and training to implement (Graetz, Mastropiera & Scruggs, 2006).
The avail® revolutionary software allows support staff, parents, and educators to monitor from a distance by receiving notifications when tasks are viewed. This empowers the individual to confidently self-manage their daily events independently, while the parent can safely monitor from a distance. A key element of avail® i.e. video modelling has been found to successfully teach independence via community skills such as purchasing among a group of students: Alcantra, P.R. (1994), Haring, T.G., Kennedy, C.H., Adams, M. J., & Pitts-Conway, V. (1987).
Independence has been observed to be achieved through the use of a video-prompting procedure on an iPod to help instruct a young man with developmental disabilities to complete vocational tasks in a competitive work setting (Van Laarhoven et al., 2009). It is important to keep in mind the various areas in an individual’s life that may benefit from such achievements.
Furthermore, Mechling et al., 2009 found a combination of prompts such as pictorial, auditory and video prompts to be successful in increasing the independent skills acquired such as cooking among students with ASD. This is extremely relative to avail™ as it provides the ability to use a single method or combination of prompts to adapt to the individual’s ability or desires whilst learning an independent goal.
While the above research supports the strategies used in avail®, it is necessary to research the effectiveness of avail® as a prompting system, that achieved and measures learning. The Irish Research Council is currently exploring this, and we welcome any other studies who wish to conduct similar research.
