ABSTRACT
Abstract This study investigated the effects of pseudoword discrimination training that either required or didn't require selection responses upon control by stimulus elements and recombination of elements, and upon stimulus observation. Eight undergraduate students were exposed to two conditions with discriminative training and stimulus control test. Condition SEL required selecting the S+, and condition OBS only required observation. Test results suggest that selection responses did not affect control by the elements or the recombination of elements in the pseudowords. Four participants presented restricted stimulus control. This control was extended in the additional DOR condition, which required differential observation of the elements, and was accompanied by increases in S+ observation. Increased stimulus control, promoted by the DOR, should still be evaluated independently of previous teaching conditions.
Resumo Este estudo investigou o efeito de treino discriminativo de pseudopalavras com e sem a exigência de resposta de seleção sobre o controle por elementos e recombinações de elementos e sobre a observação dos estímulos. Oito universitários realizaram duas condições com treino discriminativo e teste de controle de estímulos. Na condição SEL, requeria-se uma resposta de seleção do S+; na condição OBS, apenas a observação. A resposta de seleção não foi determinante no controle pelos elementos e pela recombinação de elementos. Quatro participantes apresentaram controle restrito. Esse controle foi ampliado na condição adicional DOR, que requeria a observação diferencial dos elementos, e foi acompanhado por aumento da observação do S+. A ampliação do controle de estímulos, ocasionada pelo DOR, ainda requer avaliação independente de condições de ensino anteriores.
ABSTRACT
Objective To investigate the satisfaction degree of students and teachers towards PBL teaching method and to provide a basis for continuing to carry out PBL teaching.Methods Anonymous questionnaires of PBL teaching method in teaching plan and procedure was conducted among 49students (2008 grade) and teachers.SPSS 13.0 software package was used to analyze the data and P ＜ 0.05 stands for statistically significant differences.Results Both students and teachers were satisfied.Teachers' evaluation scores of 17 projects were all higher than 4 points and students' evaluation scores of 13 projects were all higher than 4 points; scores for the rest projects were all higher than 3 points.Conclusions PBL teaching method combined with stomatology is effective and measures should be taken to strengthen the management of PBL teaching in stomatology.
