Discrete Trial Teaching (DTT) is a teaching method that involves fast-paced trials designed to teach basic skills by breaking them into smaller components, typically conducted in a one-on-one setting. Treatment integrity has proven to be of great importance in DTT, with skill acquisition occurring at higher rates when treatment integrity is high. While research has shown that verbal and written feedback are effective in training staff to conduct DTT, there is still a need for research on the use of individualized interventions based on performance assessments. This study used a multiple-probe across participants design, and demonstrated that a one-on-one session including interventions such as feedback, practice, treatment integrity checklists, and/or antecedent interventions is an effective method for increasing treatment integrity and implementation of DTT. The three participants that took part in the individualized interventions all displayed increases in proficiency of delivering DTT trials. / Applied Behavioral Analysis

Behavioral Skills Training (BST) is an evidence-based practice used to teach a wide variety of skills to different populations (Erhard et al., 2019; Parson et al., 2012; Reed et al., 2018; Tomlinso et al., 2018). BST can be used to perform Discrete-trial teaching (DTT), which is an effective teaching procedure that simplifies teaching for children with developmental disabilities and helps to expand their repertoires (Sarokoff & Sturmey, 2004). In the past, virtual-BST, which is a cost-effective and convenient method (LeBlanc et al., 2020; Tomlinson et al., 2018), has been used to teach individuals how to implement Applied Behavior Analysis interventions (Rios et al., 2020). The purpose of the current study was to compare the effectiveness of in-person BST and virtual BST to train three caregivers and three behavior technicians to implement DTT with children diagnosed with autism spectrum disorder. Using a multiple baseline across participants design, results of the current study indicated that, after the introduction of BST, participants in both groups (i.e., in-person BST and virtual BST) showed a high improvement in DTT implementation skills compared to baseline. Findings suggest that both modalities of BST are effective methods for training individuals on how to implement DTT.

In teacher preparation, more effective pathways and practices are needed for preparing, placing, and supporting beginning teachers and principals (Darling-Hammond, 2010; U.S. Department of Education, 2009b). A common issue in the field of special education is the lack of skill transfer from one setting to another (Dieker, Hynes, Hughes, & Smith, 2008). It has been posited that “practicing up” is not ethical in that novice teachers must attempt to teach with a limited knowledge of appropriate pedagogy and skill (Dieker et al., 2008). The new challenge becomes finding an effective mechanism that provides essential learning experiences and opportunities to refine teaching techniques to the highest standards of fidelity in a safely controlled and coordinated environment (Odom, 2009). Perhaps because of the ethical concerns in honing teacher skills on actual children, and despite the strong demand for professionals who are trained in discrete trial teaching (DTT), few studies have been published on training methodologies and fidelity of implementation (Fazzio, Martin, Arnal, & Yu, 2009). The training of teachers to implement evidence-based interventions such as DTT with fidelity while they are working with students with ASD cannot be over-emphasized in a teacher preparation program (Scheuermann, Webber, Boutot, & Goodwin, 2003; Simpson, 2004; 2005). The researcher utilized the TLE TeachLivE simulation classroom laboratory at the University of Central Florida as a mechanism to infuse cutting-edge technology and learning activities within program/project coursework. The TLE TeachLivE virtual classroom serves as a venue for pre-service and practicing teachers to safely gain proficiency and iv enhance fidelity of implementation of evidence-based practices. Participants experienced an immersive, real-time environment that featured interactions with Austin, an avatar that portrayed a student with autism. A trained interactor remotely controlled the behavior and responses of the avatar with which teachers engaged for practice sessions consisting of ten discrete trials. Between sessions, participants received individualized clinical coaching (ICC) on their performance. Upon termination of the intervention, two generalization probes were conducted to measure retention of fidelity over time within actual classroom settings. Results indicated that all five participants strongly benefited from learning DTT with ICC in the TLE TeachLivE learning platform. Across participants, the overall mean gain in fidelity from baseline phase (14%) to intervention phase (80%) was 66%. The fidelity means of participants in the generalization phase held to 90%, thus supporting the use of virtual environments for teacher preparation. Mean time among participants to attain higher than mastery level performance of 90% in intervention was 1.25 hours. This resulted in shorter training times than previously researched training programs (Arnal et al., 2007; Fazzio et al., 2009; Leblanc, & Luiselli, 2005; Thiessen et al., 2009). This investigation endeavored to reduce the potential of diminished pupil learning gains as a necessary consequence when honing skills in the appropriate delivery of instruction of discrete trial teaching.

Many professionals have successfully implemented discrete trial teaching in the past. However, there have not been extensive studies examining the accuracy of discrete trial teaching implementation. This study investigated the use of Bug in Ear feedback on the accuracy of discrete trial teaching implementation among two pre-service teachers majoring in elementary education and one pre-service teacher majoring in exceptional education. An adult confederate was used to receive discrete trial teaching. Implementing a multiple baseline across participants design, this study examined whether there was a functional relationship between receiving Bug in Ear feedback and the accuracy of discrete trial teaching implementation. The discrete trial teaching evaluation form was utilized to measure the accuracy of discrete trial teaching implementation. The findings demonstrated an increase in the discrete trial teaching implementation accuracy after Bug in Ear feedback was introduced. Participants agreed that using a self-instruction manual combined with receiving Bug in Ear feedback was beneficial in learning to implement discrete trial teaching

Diploma thesis focuses on effect of positive reinforcement and it's application in the learning process. The thesis is divided into two parts - theoretical and analytical. Theoretical part describes importance of positive reinforcement in a learning process and behavior overall. How organisms acquire new skills and how effective teaching methods look like. Analytical part provides practical use of positive reinforcement in an effective teaching method called Discrete Trial Teaching. It's application, use, and correct implementation is provided through an example of teaching a motor imitation behavior.
