Behavior-analytic procedures have been identified as effective for training teachers working in special education. However, most are implemented in a face-to-face and individualized manner, leading to a lower cost-benefit ratio compared to online training. This study evaluated the efficacy of a Personalized Online Instruction System (POIS) in teaching declarative knowledge about autism diagnosis, basic concepts of Behavior Analysis, and the implementation of three behavior-analytic procedures (Multiple Stimulus Without Replacement Preference Assessment, Brief Functional Analysis, and Functional Communication Training) to thirty-five special education teachers. All teachers completed the POIS modules, organized sequentially and individually, including video instruction, written material, and written and computerized feedback. Progression between modules was contingent on meeting minimum performance criteria in posttests. Nine participants underwent generalization tests to verify the practical application of procedural knowledge in simulated trials with confederates. These tests involved implementing the three learned behavior-analytic procedures, assessing the accuracy of correct responses. Results indicated that the POIS was effective in teaching declarative knowledge. However, in the generalization test, no participant met the criterion to independently implement the procedures, thus requiring additional training with feedback. This study contributes to the development of efficient and accessible teacher training methodologies, which highlights the importance of combining online instructional systems with in-person strategies to maximize learning and practical application of behavior-analytic repertoires in special education.

Procedimento de observação de pareamentos de estímulos com e sem exigência de resposta ecoica: efeitos na emergência de intraverbais em crianças com autismo
(Universidade Federal do Pará, 2019-04-04) COSTA, Malena Russelakis Carneiro; SOUZA, Carlos Barbosa Alves de; http://lattes.cnpq.br/1264063598919201
The teaching of intraverbals is mainly studied through procedures that involve differential reinforcement such as tact training and listener training. However, another procedure called ‘Stimulus Pairing Observation Procedure’ (SPOP) emerged as an alternative to verify the emergence of verbal repertoires. This procedure consists of observation of stimuli presented contiguously, where the only response required is the observation and does not involve differential reinforcement of any responses. Studies have shown that verbal operants can be established through SPOP, and have also emphasized the role of echoic behavior as an mediator in tact, listener, and intraverbal responses emergence. The present study compared the efficacy of the SPOP with and without requirement of echoic response in emergence of intraverbals in three children with autism. A multiple probe design with alternating treatment between participants was used. The procedure had seven phases: 1) Evaluation of syllable articulation; 2) Initial Intraverbal Probe; 3) Tact Training; 4) Baseline; 5) Implementation of treatments; 6) Generalization test; 7) Maintenance test. The results showed the SPOP’s efficacy for intraverbals induction and suggested a facilitating role of the echoic. Possible carry-over effects of treatments, extinction of responses in the experimental context and the use of conditioned reinforcers as part of the SPOP are discussed.
