多主体评定青少年外化问题行为的一致性问题

以529名城乡初一学生为被试进行短期追踪研究,考察了青少年自我、同伴和教师三种主体对学校情境中的青少年外化问题行为评定的一致性问题。采用相关分析、多质多法分析、验证性因素分析和检出率分析对三种主体的评定结果进行了分析比较。结果显示,青少年自我、同伴和教师对外化问题行为的评定只存在中低程度的一致性;通过同伴评定测得的四种外化问题行为群之间的相关性高于通过教师评定和自我报告测得的结果,而自我报告测得的四种外化问题行为群之间的相关性最低。不同报告主体对青少年外化问题行为评定的跨时间稳定性存在差异,同伴评定的稳定性最高,其次为教师评定,青少年自我报告的稳定性最低。通过同伴评定测得的结果对多主体评定的解释率高于教师评定和自我报告的结果,自我报告的结果对多主体评定的解释率最低。三种主体所检出的不同形式的外化问题行为的人数比例没有呈现出规律性的差异,只有通过同伴评定检出的不同形式的外化问题行为者的人数比例随着检出标准的提高而减小     

Promoting principals' managerial involvement in instructional improvement

Studies of school leadership suggest that visiting classrooms, emphasizing achievement and training, and supporting teachers are important indicators of the effectiveness of school principals. The utility of a behavior-analytic program to support the enhancement of these behaviors in 2 school principals and the impact of their involvement upon teachers' and students' performances in three classes were examined in two experiments, one at an elementary school and another at a secondary school. Treatment conditions consisted of helping the principal or teacher to schedule his or her time and to use goal setting, feedback, and praise. A withdrawal design (Experiment 1) and a multiple baseline across classrooms (Experiment 2) showed that the principal's and teacher's rates of praise, feedback, and goal setting increased during the intervention, and were associated with improvements in the academic performance of the students. In the future, school psychologists might analyze the impact of involving themselves in supporting the principal's involvement in improving students' and teachers' performances or in playing a similar leadership role themselves.     

Teacher Training: Effects of Directed Rehearsal on the Teaching Skills of Physical Education Majors

Directed rehearsal was used to improve the teaching skills of six preservice elementary physical education teachers during a teaching practicum. The teaching skills lesson introduction, lesson closure, task presentation, and general and specific subject-matter feedback were assessed using a multiple baseline design across behaviors for each teacher. Social validity, in the form of the acceptability of directed rehearsal as a teacher training intervention, was also assessed using a questionnaire. Directed rehearsal was effective in improving the teaching skills of the teachers to either 100% correct implementation or, in the case of subject-matter feedback, to an established rate. In addition, the intervention was acceptable to the teachers and the practicum instructor. These results extend both the error correction and the research on teacher education literatures.     

Teachers' Ratings of Attention-Deficit Hyperactivity Disorder and Decisions for Referral for Services in Taiwan

We examined the relationship between elementary teachers' perceptions and ratings of Attention-Deficit Hyperactivity Disorder (ADHD) symptoms of students and their referral decisions in public schools in Taiwan. One hundred and twenty-one homeroom teachers were randomly selected from six public elementary schools in Taipei County, Taiwan, to participate in the study. The study contained two groups of children, a random sample (n — 478) and a nominated sample (n = 219). Results of the discriminant analyses showed that Chinese teachers' ratings of ADHD could predict group membership as to whether a student had been or might be referred. This study found that, despite the fact that Chinese teachers believed children with scores two standard deviations above the mean had behavior problems, teachers decided not to refer those students. Teachers were more likely to refer children whose scores were three standard deviations above the mean.     

Behavioral Characteristics of DSM-IV ADHD Subtypes in a School-Based Population

From an ethnically diverse sample of 2,744 school children, 221 attention deficit hyperactivity disorder (ADHD) [123 (4.5%) predominantly inattentive (IA), 47 (1.7%) predominantly hyperactive/impulsive (HI), and 51 (1.9%) combined type (C)] were identified using teacher ratings on a Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) symptom checklist. Subjects were compared to 221 controls on teacher ratings of behavioral, academic, and social functioning. The results revealed relatively independent areas of impairment for each diagnostic group. The IA children were impaired in all areas, but were rated as displaying more appropriate behavior and fewer externalizing problems than HI or C children. The HI group displayed externalizing and social problems, but was rated as no different than controls in learning or internalizing problems. The C group demonstrated severe and pervasive difficulties across domains. These findings support the validity of the DSM-IV ADHD subtypes; all ADHD groups demonstrated impairment relative to controls, but show different patterns of behavioral characteristics.     

CHANGES IN STUDENT AND TEACHER RESPONSES IN OBSERVED AND GENERALIZED SETTINGS AS A FUNCTION OF SUPERVISOR OBSERVATIONS

Two studies are reported in which the effects of supervisor observations of teachers' performance rate and accuracy on both teachers' and severely handicapped students' behaviors were compared with baseline supervisor observations that did not specify rate and accuracy feedback. The latter observation procedure (nonspecific feedback) was more typical of the existing practices of school supervisors. The dependent variables for the teachers were rate and accuracy of teacher behaviors to student responses in individualized instructional settings involving discrete trials or task-analysis steps. The dependent variables for students were the rates of correct and incorrect responding to teacher presentations during the supervisor observation periods. Both studies used a multiple baseline design. The results of Study 1 showed that there were educationally significant changes in teacher and, in turn, student performance as a result of the use of the rate and accuracy procedure. The results of Study 2 replicated those of Study 1 while correcting limitations of Study 1. This latter study also demonstrated that the observation effects of the procedure generalized to teacher performance throughout the day. The results are discussed in terms of the efficiency and cost effectiveness of the procedure to train, monitor, and reinforce teacher effectiveness.     

INSTRUCTIONS,FEEDBACK, PRAISE,BONUS PAYMENTS,AND TEACHER BEHAVIOR1

The study was conducted within a training and demonstration center for teachers from several different school districts. The teachers staffing the center were employees of the host school district who volunteered to serve in the center. Unfortunately, these volunteers did not always use the program materials appropriately and therefore did not always provide clear models for visiting teachers. In particular, four of the volunteer teachers did not always instruct their students from the appropriate reading text, even when encouraged to do so by the principal of the school in which the center was located. Various procedures were employed to alter this situation. The experimenter, (associate director of the training and demonstration center) provided instructions, feedback, and praise regarding use of the appropriate reading text. These procedures had clear effects with only one teacher. Then, merit or bonus payments were provided for teachers who used the appropriate reading text for criterion periods of time; a procedure that was very effective with all four teachers. The problem worked on in this study is typical of those faced by workers in public institutions where change cannot be brought about by the researcher's authority. All teachers in the present study had the necessary skills to demonstrate accurately the prescribed program procedures, but they did not always do so until the bonus payment was used. Although the bonus payment procedure might be inappropriate in some school situations, the procedure could easily be adjusted to accommodate the established practices of many schools. For example, establishment of explicit performance criterion and use of in-service stipends for meeting criterion performance during school hours, rather than attendance at meetings after school, might well be comparably effective.     

Effects of implementing a token economy on teacher attending behavior

After systematic attempts to increase a teacher's positive responding to her first-grade students, a token-economy system was implemented as a "last resort". On-task student behavior and relative frequency of positive and negative teacher comments were systematically observed. Data indicated that institution of the token system was associated with a relatively higher percentage of positive than negative comments. Termination and re-implementation of the token system caused reversals of the teacher's behavior.     

THE TIMEOUT RIBBON: A NONEXCLUSIONARY TIMEOUT PROCEDURE1

Recently, the use of timeout rooms has been questioned by various agencies, and some have adopted policies that prohibit or greatly restrict exclusionary timeout. The present study developed a timeout procedure that did not require removal of the misbehaver from the learning environment. The procedure was applied to the disruptive behaviors of five severely retarded children in an institutional special-education classroom. An observer prompted all teacher behaviors related to the procedures to assure their precise implementation. After baseline, a reinforcement-only condition was implemented. Each child was given a different colored ribbon to wear as a tie and received edibles and praise every few minutes for good behavior and for wearing the ribbon. When timeout was added, a child's ribbon was removed for any instance of misbehavior and teacher attention and participation in activities ceased for three minutes or until the misbehavior stopped. Reinforcement continued at other times for appropriate behavior. An ABCBC reversal design was used to demonstrate control of the behavior by the conditions applied. On average, the children misbehaved 42% and 32% of the time during the baseline and reinforcement conditions respectively but only 6% of the time during the timeout conditions. A followup probe during the new school year revealed that the teacher was able to conduct the procedure independently and that the children's disruptive behaviors were maintained at low levels. The practicality and acceptability of the procedure were supported further by the successful implementation of the procedure by a teacher in another state and by responses to a questionnaire given to 40 mental health professionals. The ribbon procedure appears to be a viable form of timeout, provided that disruptive behaviors during timeout can be tolerated within the setting, or a backup procedure such as exclusionary timeout is available when needed.     

Generalization of parent-training results

Two experiments were conducted to assess the generalized effects of several different parent/teacher training programs. In Experiment I it was found that a brief demonstration of how to teach an autistic child new behaviors was sufficient to teach parents how to teach those children those behaviors. However, generalization to new child-target behaviors did not take place. Another parent training program, which did not demonstrate how to teach any one specific child behavior, but was based on teaching the use of general behavior-modification procedures, was effective in teaching the parents how to teach new child-target behaviors. Experiment II then provided analyses of the individual effects of several components of the generalized training program. The results showed that videotape illustrations of the procedures, without the presence of a master teacher, were sufficient to teach the adults. However, sub-parts of the videotapes produced highly specific training results, with each component changing corresponding areas of the adults' behaviors. Viewing of the entire package was necessary before the adults were able to improve the autistic children's behaviors. The study as a whole suggests the importance of obtaining multiple measures of the effects of parent and teacher training programs, including measures of acquisition and generalization of both adult and child behaviors.
