教学实验中的处理忠实度

实验处理的忠实度是指主试在实验中实际施加的处理与预定处理之间的一致程度,它是影响实验研究效度和结论的重要因素。教学实验的处理忠实度受实验设计、培训、教学情境、教师、学生等多种因素影响,完善实验设计、进行系统培训、实施预备试验、监控实验过程是提升教学实验处理忠实度的重要途径。教学实验的处理忠实度可以通过现场观察、作品分析、教师报告等方式进行评估。     

Providing Practicing Teachers Classroom Management Professional Development in a Brief Self-Study Format

This study examined the impact of a time efficient self-study method for providing practicing teachers with job-embedded professional development targeting specific classroom management skills. The training method employed print packets and videotapes that provided models of effective classroom management strategies for instruction-giving, praise, and time out. Participants were three master’s level speech therapists certified to teach speech and language delayed preschool children. The training materials were evaluated through observations of the teachers’ implementation of targeted practices in a multiple baseline across participants. Results indicated increases in all participants use of the management skills after training. The results suggest that this type of training method may help teachers increase their use of effective classroom management procedures. It is potentially noteworthy that the training program examined herein was largely teacher managed and was quite brief. Future directions and limitations of the study are discussed.Natalie J.

Do secondary school students make use of effective study strategies when they study on their own?

Although there is a large body of evidence for the utility of particular study strategies such as retrieval practice and distributed practice as memory‐enhancing instruments, they are seldom used by learners in educational practice. Thus far, the research on the use of these study strategies has focused only on undergraduate university students, oftentimes only investigating a set of predefined strategies. The question, thus, remains whether these results are generalisable to secondary school students. The present study is the first to explore the use of different study strategies by secondary school students. With the use of an open question, 316 secondary school students from three different secondary school levels were asked how they prepare for an exam when they are studying by themselves. The results show that secondary school students use study strategies considered to be suboptimal. In the discussion, we compare our findings with results of previous studies among undergraduate university students.     

宫内生长受限分娩时间决策

宫内生长受限（IUGR）是导致围产儿死亡的常见原因之一。分娩时间是IUGR临床决策的关键问题,IUGR分娩时间的临床决策需对其病因、病理生理、健康效益、医疗代价、产前检测等进行辩证综合分析,采用循证医学的方法,科学决策,个体化决策,力求减少不良后果发生。     

A preliminary analysis of instructional control in the maintenance of appropriate behavior

This bridge study evaluated the effects of contingency-specifying instructions (CSIs) and incomplete instructions (IIs) in terms of establishing instructional control of appropriate behavior. Results suggested that instructional control and maintenance were achieved with CSIs but not with IIs. Results are discussed in terms of the potential use of instructional control in the maintenance of appropriate behavior for children with attention deficit hyperactivity disorder.     

Instructional effects on performance in a matching-to-sample study

Conducting studies using an undergraduate participant pool is fraught with difficulties. Among them are problems with adequately motivating subjects both to come to the study, and once there, to actively engage the experimental task. Thirty-one college students participated in a matching-to-sample (MTS) study involving substantial training, testing, retraining, and retesting of conditional discriminations and equivalence relations among four 4-member classes of nonsensical words. The study was conducted during the end of the semester, when performance often had been observed to be poorer than at other points in the semester. Eleven of the participants, in addition to standard instructions about the task, received additional instructions specifying molar consequences for high rates of "correct" responses throughout the procedure. This subset of participants displayed markedly improved performance as compared to those who did not receive the additional instructions. Results suggest that specification of molar contingencies improves participants' sensitivity to molecular contingencies within the study. Instructions that specify and increase the consequential functions of feedback provided during MTS trials may be one means of reducing unwanted variability in human MTS performance.     

心理学毕业生专业技能调查及其对专业改革的启示

通过对204名心理系历届本科毕业生的调查,结论如下：(1)毕业生对心理学专业教学总体满意度一般,其中对专业实践安排的满意度最低;(2)毕业生认为最重要的技能是“进行心理活动课程”和“心理咨询”,最欠缺的技能是“心理治疗”和“心理咨询”;(3)心理学应用技能课程包含“心理咨询及治疗”、“心理课程及教育”、“心理测评及应用”三个因素。在调查基础上,本文提出了心理学专业改革的设想。     

Ageism in Mental Health and Health Care: A Critical Review

Discussions of aging and mental health widely assume that ageism among mental health providers is an important factor limiting access to mental health services for older adults. Given the widespread citation of ageism as a problem, we critically review the history of the ageism construct, and evidence for its existence in both mental health and medical professionals. There is surprisingly little empirical evidence for age bias among mental health providers. Considerable evidence does suggest differential medical treatment for older adults in such diverse areas as physician–patient interaction, use of screening procedures, and treatment of varied medical problems, although it is unclear whether age bias accounts for these differences. We suggest that innovations in delivery of psychological services, such as collaborative medical/psychological care in primary care settings, may ultimately prove more useful in improving access to mental health services than efforts to combat ageism.     

Cracks in a postdisaster service delivery network

Poor linkage cracks are defined and identified empirically in a postdisaster service delivery network. These cracks exist when essential services are provided only by isolated or peripheral clusters of organizations. Network analysis is used to identify the isolated and peripheral clusters of organizations. Measures of experience in responding to disasters and service capacity are used to identify the organizations whose services are essential in the network. Cracks prevent the network from responding effectively in the aftermath of a disaster. Suggestions are made for using network analysis to identify cracks and to improve planning and coordination in all kinds of service networks.

Contingency and choice: The implications of matching theory for classroom instruction

This paper describes a mathematical account of behavior known as matching theory. Matching theory evolved out of basic operant research and assumes that individuals can engage in a variety of behaviors at any moment, but they choose one to the exclusion of others. According to the matching equation, choices in behavior match the relative amount of reinforcement provided for each alternative. Although the principles of matching theory have proven useful in developing novel treatment strategies, few data exist validating the matching equation in natural human environments. Recent applications of matching theory to children's classroom behavior are described, and the implications of matching theory for classroom management and effective teaching are discussed.
