The reliability of test scores for the pervasive developmental disorders rating scale

The Pervasive Developmental Disorders Rating Scale (PDDRS; Eaves, 1993) is a screening instrument used in the assessment of autistic disorder. In this study, the reliability of test scores for the PDDRS was examined with three samples. The first sample consisted of 456 participants ranging in age from 1 to 12 years old and the second sample consisted of 111 participants in the 13 to 24 year‐old range. Additionally, the test‐retest reliability of scores for the PDDRS was examined with a sample of 40 participants. The results indicated that coefficient alpha for the PDDRS Total Score was adequate for screening purposes (r = .89) for both age groups. The results of the test‐retest study also suggested that PDDRS had adequate test‐retest reliability (r = .92) for the PDDRS Total Score. © 2002 Wiley Periodicals, Inc.

一个关于工作场所学习的建议性概念框架:对人力资源开发理论建设与研究的启示

人力资源开发领域的学者和实践者都非常关注工作场所学习。关于正式培训和非正式学习,一直以来形成了大量的研究和讨论。本文从人力资源开发角度,结合已有的大量文献,提出了一个工作场所学习的概念性框架,框架包括三个互相作用的变量:学习的场所、在发展和传授学习经验时所制定的计划的程度和学习过程中培训者、推动者和其他人的角色。本文还讨论了这一框架对人力资源开发领域中理论建设和研究的启示。     

An Assessment of the Nonparametric Approach for Evaluating the Fit of Item Response Models

As item response theory has been more widely applied, investigating the fit of a parametric model becomes an important part of the measurement process. There is a lack of promising solutions to the detection of model misfit in IRT. Douglas and Cohen introduced a general nonparametric approach, RISE (Root Integrated Squared Error), for detecting model misfit. The purposes of this study were to extend the use of RISE to more general and comprehensive applications by manipulating a variety of factors (e.g., test length, sample size, IRT models, ability distribution). The results from the simulation study demonstrated that RISE outperformed G² and S‐X² in that it controlled Type I error rates and provided adequate power under the studied conditions. In the empirical study, RISE detected reasonable numbers of misfitting items compared to G² and S‐X², and RISE gave a much clearer picture of the location and magnitude of misfit for each misfitting item. In addition, there was no practical consequence to classification before and after replacement of misfitting items detected by three fit statistics.     

Classroom Discipline without Punishment

Regrettably, cheating is widespread on all levels of our educational system. Effective monitoring and judicial review processes that ensure that students who cheat are subjected to appropriate disciplinary action are essential. However, policing is not enough. We must go beyond policing to change the culture of the classroom in ways that discourage cheating. This includes doing a better job of explaining why cheating is unacceptable, structuring exams and writing assignments in ways that make it difficult for students to cheat, and fostering an environment of mutual respect in the classroom that encourages students to buy into the educational process, rather than attempt to subvert it.     

FACULTY WORKLIFE: Establishing Benchmarks Across Groups

Pressures on colleges and universities have spawned numerous studies to improve our understanding of faculty and their worklives, including examinations of faculty satisfaction, morale, motivation and productivity, reward, and retention and turnover. In response to external pressures for improved accountability in higher education, institutional leaders seek to identify outcome measures and generate benchmarks that can be used to assess change over time. The purpose of this study is to propose a structural model of faculty worklife and to test its generalizability by examining possible differences in the model across three cross-sectional samples of probationary faculty at a major research university. Identified trends in faculty perceptions about their worklife over time can be used as benchmarks to aid institutions in retaining faculty by monitoring and improving aspects of their worklives.     

Does creativity have a place in classroom discussions? Prospective teachers’ response preferences

The purpose of this study was to examine prospective middle and secondary teachers’ preferences for unique versus relevant student responses during classroom discussions. Results indicate that, on average, prospective teachers (N = 70) preferred relevance to uniqueness in student responses. In addition, results of regression analysis indicate that prospective teachers’ preference for unique responses varied as a function of grade level and academic subject area. Finally, analysis of written explanations revealed nuanced reasons for prospective teachers’ preferences ranging from viewing unique responses as potentially distracting to viewing any response as acceptable because of a desire to encourage student participation. Implications for future research and teacher education are discussed.     

Predicting reading level in grades 1 to 6 from listening level and decoding level: Testing theory relevant to the simple view of reading

The relationships among pronunciation level (decoding), verbal level (listening), and accuracy level (reading) were investigated in grades 1 to 6, and for students who are in the advanced phase of decoding. The data collected were used to investigate the validity of the simple view of reading and the causal model of reading achievement which holds that pronunciation level (P_L) and verbal level (V_L) are the proximal causes of accuracy level (A_L). A total of 135 students in grades 1-6 were given measures of nonword decoding, real word decoding, listening, and reading. All of the reliable variation in an indicant of the level of reading ability, A_L, could be predicted from an indicant of the level of ability to decode real words, P_L, and an indicant of listening level, V_L. Furthermore, the strong relationship between pronunciation level, P_L, and accuracy level, A_L, did not evaporate for the students who had mastered basic decoding skills, as measured by nonword decoding tests. The correlations between pronunciation level, P_L, and accuracy level, A_L, were high even for students in grades 5 and 6, most of whom probably had progressed beyond the alphabetic phase (phonological recoding). Correlational support was found for the simple view of reading and the causal model which holds that A_L is equal to the square root of the product of V_L and P_L. The above theory and supporting data were interpreted as suggesting that the level of reading accuracy, A_L, of students can be improved the most throughout grades 1 to 6 by emphasizing instruction that will improve pronunciation level, or decoding, even for children who have progressed beyond the beginning to read phase which involves learning the alphabetic principal, or phonological recoding.     

Commentary: Advances in research on sourcing—source credibility and reliable processes for producing knowledge claims

In our commentary on this excellent set of articles on Sourcing in the Reading Process, we endeavor to synthesize the findings from the seven articles and discuss future research. We discuss significant contributions related to source memory, source evaluation, use of sources in action and belief, integration of information from multiple sources, and instruction in sourcing. Next we discuss several issues for future research raised by these articles, including expert sourcing, embedded sources, epistemic justice, and explanations of disagreement. Finally, we argue that the credibility of sources and their claims is determined by the reliability of the processes used by the sources to produce their claims. Our focus on the reliability of processes used by sources has implications for understanding sourcing processes, for evaluating normative claims about which sources are most reliable, for explaining how people evaluate sources, and for developing instruction on sourcing.
