This study evaluated the efficacy of a personalized system of instruction to teach checking account skills to persons with mild disabilities. Using a self-paced manual, 8 participants in two groups were taught to write checks, complete deposit slips, and reconcile monthly bank statements. Four participants were assessed for generalization from the classroom to community sites and demonstrated nearly perfect performance. A multiple probe design showed that acquisition occurred sequentially for each skill only after training using the self-paced manual. Follow-up sessions demonstrated that participants maintained the checking account skills. The results provide evidence of the effectiveness and adaptability of a personalized system of instruction for teaching complex monetary skills to persons with mild disabilities.  相似文献

We evaluated the effects of two procedures for teaching four developmentally disabled children to respond yes/no appropriately. During baseline, tutoring was conducted in which five known items were individually presented with the question, “Is this a_____?”, followed either by access to requested items or by remedial prompting contingent on responding. When tutoring did not improve performance, instruction was embedded in the regular classroom activities. In this condition, items requested by students were either presented or withheld on the basis of their response to the question, “Do you want ______?”. Increases in correa responding were confirmed by a multiple-baseline design across all four students and were maintained with the introduction of new items. However, generalization to “Is this a_____?” questions did not occur in the tutoring setting until specifically programmed. Subsequently, students also demonstrated appropriate yes/no responding to questions involving actions, possession, and spatial relations.  相似文献

Three experiments analyzed the effectiveness of a textbook incorporating "concept programming" in producing concept formation in university students. The concept programming portion of each lesson requires students to determine which concept is illustrated by each of 20 short fictional stories about everyday behavioral situations. The stories are selected to illustrate and contrast the concepts of that lesson. Student responses are heavily prompted during the initial stories of each lesson. The first experiment demonstrated that students generalize to entirely novel examples from the examples in the textbook. The second experiment demonstrated that the concept programming portion of the textbook is a critical component in producing generalization. The third experiment demonstrated that the amount of concept formation produced by the concept programmed textbook is greater than that produced by a widely used standard textbook.  相似文献

Reading comprehension, indicated by motor behavior and multiple-choice picture selection called for in written instructions, was taught to an autistic child using verbal prompts, modelling, and physical guidance. The child was rewarded for correct behaviors to training items; nonrewarded probes were used to assess generalization. Probable maintaining events were assessed through their sequential removal in a reversal design. Results showed: (a) following acquisition, performance was maintained at a near-100% level when candy, praise, attention, and training were removed, (b) absence of other persons was correlated with a marked decrease in performance, whereas their presence was associated with performance at near 100%, and (c) performance generalized to probes and across experimenters. Rewards, which may have been reinforcing during acquisition, did not appear necessary to maintain later performance. Instead, presence of others (a setting event) was demonstrated to have control over maintained performance.  相似文献

We present a review of the existing research on instructive feedback. Instructive feedback is a method of presenting extra, non-target stimuli in the consequent events of instructional trials (e.g., during praise statements). Students are not required to respond to those additional stimuli and are not reinforced if they do. The research is reviewed in terms of the characteristics of participants involved, the settings and instructional variables used, and the findings that emerged. The findings indicate that a wide range of students by age and disability were included and that most studies occurred in special education contexts. When used with response prompting procedures in a variety of direct instructional arrangements, students acquire and maintain some of the instructive feedback stimuli. Thus, teachers are encouraged to use instructive feedback in their direct instructional activities. Areas of future research include using instructive feedback in new contexts and examining methods for presenting instructive feedback. In addition, the use of instructive feedback to influence future learning and stimulus class formation should be investigated.  相似文献

We examined 24 studies to determine the effects on word recognition and reading comprehension of correcting errors during oral reading. Corrective feedback improved students' word reading accuracy on words in lists, and accuracy in reading words in passages. Some correction procedures had greater benefits than others. Successful error correction procedures share common characteristics, leading to recommendations about instruction: Teachers should (a) correct errors immediately; (b) require students to repeat the correct response; and (c) match correction procedure to the instructional situation and the learner. Several research recommendations are outlined.  相似文献

Increasingly, behavior analysts are attempting to develop interventions based on precision assessments of the situational factors surrounding a behavior of interest, those requiring reduction (as in functional analysis) or those requiring acceleration (as in ecobehavioral analysis). Using ecobehavioral assessments of naturalistic classroom instruction, we sought to identify a set of potentially effective procedures and to test their function. Using as selection criteria students' gains in academic achievement, and their observed academic behavior, we identified potentially effective versus ineffective instructional procedures used to teach language arts skills to students with learning disabilities (Study I). Subsequently, we sought to test and replicate the functionality of the identified procedures within a series of single-subject experiments. Results from a resource room application (Study II) indicated that the targeted effective procedure surpassed the targeted ineffective procedure in terms of both content mastery and the quality of students' written language samples. Results from a regular classroom application (Study III) indicated that the targeted effective procedure was also more effective than the conventional instructional procedure employed naturally by the regular education teacher. The implications of these findings are discussed.  相似文献

Two experiments are reported which test the effect of increased three-term contingency trials on students' correct and incorrect math responses. Experiment 1 included two junior high school students in need of special instruction in mathematics while in Experiment 2 two other students with similar instructional needs from the same classroom were studied. In the first experiment the increased rate of presentation (3 times the baseline rate) was done without regard to whether the antecedent teacher presentations to the student were presented vocally or in written form; in the second experiment, the rates of presentation were systematically rotated across written and vocal presentations. The dependent variables were rate per minute of correct and incorrect responses of students (vocal or written). The experiments used designs incorporating features of the multiple baseline (Students A and B) and reversal (Students B, C, and D). The data showed that increasing the number of three-term trials increased correct rates while incorrect rates remained relatively low. The second experiment replicated these findings with two other students and found that the treatment effect occurred independently with vocal and written antecedents when each was isolated. The results warrant further research to test whether or not rates of presentation of three-term contingency trials are predictors of effective instruction.  相似文献

Computers were used to evaluate the effects of supplying answers to programmed instruction frames. A group experimental design compared passive reading, covert responding to frame blanks, and actively typing answers to blanks with and without immediate confirmation of correctness. Effects of a 315-frame program, teaching elements of programmed instruction design, were evaluated by analyzing answers to posttest generalization questions and an application test. Results strongly supported the effectiveness of requiring the student to supply fragments of a terminal repertoire while working through a program. Students who could either covertly respond to frame blanks or who were required to type frame answers performed significantly better on the frame generalization posttest and, more importantly, carefully followed program rules when preparing elements of a new instructional program.  相似文献

A standardized estimation of Rorschach interrater agreement is needed. Percentage agreement, although widely used, is found to be unsuitable. Forty-one protocols from adults in both a normal and a psychiatric sample were scored by two or three scorers, making 85 scoring pairs. Percentage agreement, correlations (phi and Pearson's r ), and kappa were computed on single response, total score, and category level. Percentage agreement shows minimal variation. Even when exceeding 0.80, it can obscure major disagreements. Kappa and correlations both vary in a similar way with level of disagreement. Total score level does not give additional information compared to single score and category levels. Kappa proved to be conservative and reliable and is therefore suggested as a standard estimate.  相似文献
