PROMOTING RECIPROCAL INTERACTIONS VIA PEER INCIDENTAL TEACHING

This study evaluated peer incidental teaching as a strategy for increasing reciprocal peer interactions by children with autism. Three typical preschoolers were trained as peer tutors for 3 young children with autism. During a classroom free-play session, peer tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. A multiple baseline across the 3 target children showed replicated positive effects of the intervention. Adult supervision and assistance were then faded systematically, with resulting maintenance of increased reciprocal interactions. Multiple measures of the extent and limits of generalization suggested that 1 child increased interactions in free-play periods throughout the day, but none of the children showed increases at lunch. Teacher and peer ratings supported the social validity of positive findings.     

AN ANALYSIS OF A GROUP TEACHING PROCEDURE FOR PERSONS WITH DEVELOPMENTAL DISABILITIES

This study evaluated whether a concurrent group teaching procedure, in which all students respond simultaneously, could be used for persons with moderate or severe mental retardation. The teaching procedure used was the Task Demonstration Model, a program based on stimulus-control research and the fading techniques of behavioral psychology. Three teachers and three groups of students participated. Results showed that the teachers increased their rates of questions and instructions, positive feedback, and use of functional materials, but they reduced their rate of prompts to almost zero. Students increased their percentage and rate of correct responding as well as their engaged time. In addition, maladaptive responding, for which there were never any direct consequences, decreased from 45% to 10% for 8 of the 14 students. Results are discussed primarily in two areas: (a) changing stimulus control from teacher prompts to critical elements of the items being taught, and (b) reasons for the reduction of maladaptive behavior for 8 of the subjects.     

GENTLE TEACHING AND APPLIED BEHAVIOR ANALYSIS: A CRITICAL REVIEW

In recent years, there has been a growing controversy surrounding gentle teaching. This paper explores the nature of this controversy with particular reference to the relationship between gentle teaching and applied behavior analysis. Advantages and disadvantages of this approach are discussed, and it is suggested that gentle teaching and applied behavior analysis need not be regarded as mutually exclusive approaches to working with persons with mental retardation.     

11—14个月儿童的语言获得——成人的言语教授和儿童的模仿学习

对儿童言语记录个案的分析表明:儿童在11—14个月期间开始获得词。此时儿童所获得的词,主要是与儿童日常生活或动作相联系的名词和动词,其次是象声词。这些词语87.5％来源于成人的言语教授和儿童相应的模仿学习。 成人的言语教授和儿童相应的模仿学习总是由成人结合情景进行的,具有很高的选择性。儿童对成人言语的学习并不是简单地模仿,而是有一定的主动性和创造性,这在一定程度上规定着成人言语教授的作用。由此可见,儿童言语的获得是在人类特有的大脑以及言语器官发育的基础上,在与人们交际过程中,经过成人的言语教授,并经儿童有选择的模仿学习和概括而成的。     

American Legal argumentation: The Law and Literature/rhetoric movement

This essay discusses the most recent manifestations of the debate of the law and literature movement. The essay traces the evolution of the Law and Literature schools and identifies some of their adherents and conclusions, shows how these schools have influenced the conceptual development and teaching of American law, presents connections between the Critical Legal Studies and Law and Economics movements in the U.S., and raises questions about the Law and Literature movement.     

The Nctm Standards and the Philosophy of Mathematics

It is argued that the philosophical and epistemological beliefs about the nature of mathematics have a significant influence on the way mathematics is taught at school. In this paper, the philosophy of mathematics of the NCTM's Standards is investigated by examining is explicit assumptions regarding the teaching and learning of school mathematics. The main conceptual tool used for this purpose is the model of two dichotomous philosophies of mathematics-absolutist versus- fallibilist and their relation to mathematics pedagogy. The main conclusion is that a fallibilist view of mathematics is assumed in the Standards and that most of its pedagogical assumptions and approaches are based on this philosophy.     

Towards a new image of science: Science teaching and non-analytical philosophy of science

This paper describes an attempt to develop a pedagogy for teaching philosophy in science rather than a philosophy of science to be taught in the Bulgarian educational system.     

CONTINGENT OBSERVATION: AN EFFECTIVE AND ACCEPTABLE PROCEDURE FOR REDUCING DISRUPTIVE BEHAVIOR OF YOUNG CHILDREN IN A GROUP SETTING1

Since a major task of childhood is learning to get along in a group without disrupting other children's activities, caregivers need explicit guidelines for gentle but effective procedures for dealing with disruptive behaviors in child-care settings. In a day-care center for normal 1- and 2-yr-old children, an effort was made to develop a procedure that appeared sufficiently humane and educational to be acceptable to parents and daycare workers, and yet effective in reducing disruptive play behaviors. Caregivers used the occasion of disruptive behavior to instruct the child in appropriate alternatives, then had the child sit on the periphery and observe the appropriate social behavior of the other children, “sit and watch”, for a brief period before inviting him or her to rejoin the play activities. The effectiveness of this procedure was compared with a method commonly recommended for use with young children: instructing the child, then distracting or redirecting the child to an alternative toy or activity. Contingent observation, combining instruction with a brief timeout (from being a participant in an activity to becoming an observer of the activity), proved considerably more effective in maintaining low levels of disruptions and was considered by caregivers and parents to be an appropriate and socially acceptable method of dealing with young children's disruptive behaviors. Therefore, contingent observation can be recommended for general use in day-care programs for young children.     

AN EVALUATION OF GENTLE TEACHING AND VISUAL SCREENING IN THE REDUCTION OF STEREOTYPY

Gentle teaching and visual screening techniques have been used to control severe behavior problems in persons with mental retardation. An alternating treatments design was used to compare gentle teaching, visual screening, and a task-training condition in the reduction of the high-level stereotypy of 3 persons with mental retardation. Following a baseline phase, a task-training condition using standard behavioral techniques was implemented to establish the effects of training the subjects on the tasks. Results showed a modest decrease in stereotypy. This phase was followed by an alternating treatments phase in which visual screening, gentle teaching, and baseline conditions were compared. Both procedures were superior to the control condition in reducing stereotypic behavior, with visual screening being more effective than gentle teaching. When compared with data from the prior phase, gentle teaching was found to be more effective than task training for 2 subjects but less effective for the 3rd, whose stereotypy increased during gentle teaching. Two succeeding phases in which visual screening was implemented across two and then all three daily conditions reduced stereotypy further to near-zero levels. An additional phase with 1 subject demonstrated that the treatment effects of visual screening were easily replicated across therapists. Mixed and idiosyncratic changes in collateral behaviors occurred. For example, “bonding,” the goal of gentle teaching, occurred at the same low levels under both treatments, contrary to the predictions of gentle teaching's proponents. The results indicate that gentle teaching may not be the universal treatment of choice for stereotypy its proponents suggest, and that it requires further empirical evaluation.     

THE FACILITATIVE EFFECTS OF INCIDENTAL TEACHING ON PREPOSITION USE BY AUTISTIC CHILDREN

In a comparison of incidental teaching and traditional training procedures, three language-delayed autistic children were taught expressive use of prepositions to describe the location of preferred edibles and toys. Traditional highly structured training and incidental teaching procedures were used in a classroom setting, and generalization was assessed during free-play sessions. Results clearly indicate that incidental teaching promoted greater generalization and more spontaneous use of prepositions. These findings have important implications for language programming and teacher training, suggesting that incidental teaching should be included as a standard component of language development curricula for autistic and other developmentally delayed children.
